Tunnel blocking silos can be divided into circular, rectangular, and polygonal shapes according to the plane shape. Currently, circular and rectangular silos are widely used. "Design Specification for Reinforced Concrete Silos" (GB 50077 & mdash. Shallow silos are mainly used for short-term storage. As the natural collapse line of loose materials stored in shallow silos does not intersect the opposite silo wall, generally no material supply is formed (Figure, automatic unloading) ) .What is tunnel blocking and polishing? O room plugging PE type enamel coating is suitable for residential building, office building, interior and exterior wall decoration and waterproof, bathroom, kitchen room, swimming pool waterproof and anti-seepage. It can be used for room plugging decoration of enterprise workshop. .Brushing, the dosage range is 0.5 kg per square meter. XXianxian County, Baoding City, Hebei Province eliminates the waterproof coating and thermal insulation layer and digs out the old caulking material; if the caulking material was not originally filled, it will be along the crack A 20 × 20mm V-shaped seam is cut and cut; Leakage of water through the wall pipe: Measures to prevent leakage of the wall pipe: a. All wall pipes are buried in advance to avoid excavation afterwards. B. Increase the length of water seepage. Water flange, fixed concrete before pouring concrete. When constructing wall concrete structure, try not to use or less wall bolts to reduce leakage. When wall bolts must be installed, Lixian County, Baoding City, Hebei Province Leakage of joints must be set in the middle of the bolt. Watertight belts must be set in the middle of the road. C. Treat the surface of the wall pipe, mortar, residue and rust layer must be cleaned. D. Strengthen the vibration of concrete around the wall pipe, necessary Large flow concrete or other special treatments are used to ensure that no cracks are generated. E. The vibrator does not touch the wall pipe during pouring. For the deformation of the wall pipe due to temperature difference and uneven settlement, the gap between the wall pipe and the concrete is good. Adopt flexible connection. Firstly, the thickness of the buried joint is equal to the thickness of the wall, and the diameter is 10cm larger than the wall pipe. Then the gap between the wall pipe and the pipe is filled with asbestos cement or oil paste to suit the wear. The wall tube is deformed. Due to the large population of urban centers in modern times, the urban population is dense and the space resources are scarce. In order to alleviate this problem, we need to repair the buildings higher or deeper, so rooms and shopping malls have slowly begun to appear. But With this problem began to appear slowly. Room leaks must be related to room leak plugging measures. The room leaks can solve the hidden dangers caused by the leak. Let's take a look at the related notes of room leaks. The first part of the note: the characteristics of water Water is impenetrable, it gradually penetrates into the building by the force of wind pressure, convection, impact, adhesion, capillary and other forces, and it is not easy to detect from the surface during the penetration process. In other words, the cause of water leakage must be found In-depth analysis of "visceral" analysis and judgment can only be symptomatic. Q Zhongshan High Pressure Grouting In the future, if leakage is found in the surrounding area, it should be expanded to use samples, and the leaking point will be used for grouting. Seam glue, FUP polyurethane sealing series water-proof material is inserted into the repaired groove and filled until the surface of the segment is flat. After filling, it should also be scraped to strengthen the bonding of the sealing paste to the concrete. The interface next to the waterproof material must not have Drums, sand, honeycombs, wood chips, paper scraps, sludge, small stones, etc. must not be made on loose objects. The reason is poor adhesion, coupled with the sun's ultraviolet rays, the building's thermal expansion and contraction, and water Vapor pressure can easily cause aging and failure of the waterproof layer. The front is excellent in waterproof, such as roof waterproofing, directly on the roof surface, wall waterproofing should be directly on the external wall, leaking water tank directly on the inner layer of the water tank, water pressure will spread to other places, the dead corner of the house is not easy to construct. The "outperforms" mentioned here are relative, not absolute. Because with the development of science and technology, people on the market have introduced water-repellent materials for construction on the water surface and high-low pressure synthetic resin to produce crystals, which can also be waterproof. However, not all occasions can be successfully constructed. Therefore, it is a must, Baoding City, Hebei Province. County plugging companies should adopt frontal waterproof construction. Tunnel leak plugging is very important, especially for some room leak plugging, waterproof leak plugging, etc. Reasonable leak plugging projects have very positive significance for indoor and outdoor waterproofing. So what are the characteristics of waterproof leak plugging projects? Plugging will introduce the common crack treatment methods in waterproof plugging engineering: 1 Surface repair method For small cracks (<0.2mm), surface repair method is a simple and common repair. It is mainly suitable for the treatment of surface cracks that are stable and have no effect on the bearing capacity of the structure. Traditional treatment measures are to apply grout, epoxy cement or paint on the surface of cracks. At present, a new type of waterproof, coating-polymer modified cement-based penetrating spherical crystalline product has been widely used. It can bridge static cracks below 0.3mm, has high bonding strength with the construction surface, good weather resistance, and resistance to ultraviolet radiation. As long as the structure is not damaged, it is effective. The waterproof coating is not tight on the wall, and the water flows back into the coating. The Vu tunnel plugging reinforcement method, the tunnel plugging rectangular pool pool wall and the integral floor towel are made of mesh reinforcement. The reinforcement principle of the siding is the same as that of the two-way plate, but usually only separate reinforcement is used.

d. Pre-buried grouting pipe: To prevent water leakage between the water supply pipe and the buried casing seam, first cut the depth of the hair at the leak point to be less than 70mm. After flushing with water, install hemp ropes, and then use plugging materials for plugging Pre-buried 1-2 grouting pipes for diversion. y The white-grey wall or wool mortar should be removed, and the bathroom wall tiles should not be used in conjunction with porous masonry materials such as aerated concrete and hollow bricks. Yin and Yang Angle should be arc angles. Wall flooding height: bathroom: wash basin households The waterproofing of the balcony .X tunnel is better than waterproofing directly applied to the roof. The external wall waterproofing should be painted directly, and the leakage of the water tank should be directly painted on the inner layer of the water tank. Water pressure will spread to other places, and the dead end of the house is not easy to construct. The "ratio" mentioned here is comparative, not absolute. With the development of science and technology, some people in the market have introduced waterproof materials for back construction, and high- and low-pressure synthetic resins are good for crystals. Crystals can also be waterproof, but not all places can be successfully constructed, so positive waterproof construction must be adopted. In the honeycomb area, drill holes every 25-30cm, the depth should be the thickness of the structure, and then bury and tighten the water stopper. W Details For new masonry built with lime mortar and mixed mortar, the gray joints of the masonry need to be cut to a right angle of 10mm to enhance the adhesion between the waterproof layer and the masonry. For masonry built with cement mortar, the gray joints do not need to be removed, but those that have been jointed need to be removed. oH 2 caulking plugging method [3] Channel leakage For cracks exceeding 0.3mm, especially moving cracks, it is necessary to block, and if necessary, combined with grouting. Vv for underground engineering: Plugging underground: Plugging underground: Fracturing and plugging of oil and water wells in oil fields. Undertake: Room plugging, tunnel plugging, sewage pond plugging, culvert plugging, pool plugging, water plugging, dock plugging, mine plugging, cable trench plugging, air defense plugging, expansion joint plugging, Plugging of joints, plugging of broken cracks, plugging of pump rooms, plugging of settlement joints, plugging of dams, plugging of engineering, plugging of elevator shafts, plugging of joints, plugging of cooling towers, plugging of construction joints Leakage, underwater plugging and other waterproof plugging projects. Due to the current traffic construction needs, especially the construction of railways and cross-sea tunnels, various mountain-crossing tunnels and cross-sea tunnels are gradually increasing, and the construction requirements of various tunnels are also divided into strict and high requirements. However, there may still be tunnel leakage. For the safety of the tunnel or the safety of tunnel construction, it is necessary to plug the tunnel. The author will introduce the commonly used grouting and plugging methods in tunnel plugging. : Grouting is a new type of chemical grouting plugging technology, which uses two-liquid grouting. The proportioned seed materials are mixed with water to form a solution A, and the proportioned solid sulfur and water are stirred to make a solution B. When the two types are mixed, a polymerization reaction occurs, and the mixture is initially coagulated in 30 seconds and reacted in 2-3 minutes. When finished, it finally gels. The grouting uses a water-soluble structural layer. The slurry has a low viscosity and good permeability, and can crack under 0.1mm. The slurry can be coagulated under conditions of high water speed and large amount of water. The gel also has good impermeability, water resistance, and water resistance. Features such as erosion, colloid compressive strength is 0.01-0.06MPa, tensile strength is 0.02-0.04MPa.

The front is excellent in waterproof, such as roof waterproofing, directly on the roof surface, wall waterproofing should be directly on the external wall, leaking water tank directly on the inner layer of the water tank, water pressure will spread to other places, the dead corner of the house is not easy to construct. The "outperforms" mentioned here are relative, not absolute. Because with the development of science and technology, people on the market have introduced water-repellent materials for construction on the water surface and high- and low-pressure synthetic resins to produce crystals, which can also be waterproof. However, not all occasions can be successfully constructed. . Tunnel leak plugging is very important, especially for some room leak plugging, waterproof leak plugging, etc. Reasonable leak plugging projects have very positive significance for indoor and outdoor waterproofing. So what are the characteristics of waterproof leak plugging projects? Plugging will introduce the common crack treatment methods in waterproof plugging engineering: 1 Surface repair method For small cracks (<0.2mm), surface repair method is a simple and common repair. It is mainly suitable for the treatment of surface cracks that are stable and have no effect on the bearing capacity of the structure. Traditional treatment measures are to apply grout, epoxy cement or paint on the surface of cracks. At present, a new type of waterproof, coating-polymer modified cement-based penetrating spherical crystalline product has been widely used. Lexian pools in Baoding, Baoding, Hebei Province can plug leaks. It can bridge static cracks below 0.3mm and adhere strength to the surface being constructed. High weather resistance, UV resistance, effective as long as the structure is not damaged. Manufacturing costi In the past, white latex was painted before wallpapering, but because of its poor environmental protection, it is no longer used. Basically, the base film is applied because if the wallpaper is directly pasted, the adhesive of the glue is very strong. Strong, it is possible to pull off the base layer of the wall directly. If you first brush the base film (also called wallpaper companion), the base film can close the wall, waterproof and moisture, and increase the adhesion between the wall and the wallpaper. N requires the use of rigid and flexible combination, multi-layer fortification, key treatment, and full-section closed waterproof plugging measures, strict, strict management, and careful construction to ensure that the desired waterproof effect is achieved. As long as we do a good job of these waterproof problems, I believe that waterproofing is not so difficult, and it is easy to solve the leakage of the house. Leak plugging tells you the key points of leakage management in various parts of the room, parking lot or civil air defense works --- at the position where the settlement joints and leaks are relatively heavy, drilling is used to drill through the liner and leak the damaged position of the waterproof board The water coming to the back of the lining reduces the water pressure behind the lining, reduces the possibility of leakage in other parts, restores the drainage channel behind the tunnel lining, and cuts the vertical direction on the lining surface of the hole for the aesthetics of the lining surface. The drain groove under the pipe is made into a tubeless cavity by using a suction pipe method, and the water is drained into the gutter. It is necessary to study the location and angle of drainage holes, the performance and portability of drilling equipment. Due to severe air pollution around the country, acid rain is frequent throughout the country, especially in central and southern China. The acid rain will corrode the building and cause leakage, and even prone to room plugging. There is no exception in the cable trench, and there may be room leakage due to other complicated factors. What kind of measures should we take in this case? Let's take a look below: Enter the cable trench, And according to the water storage conditions in the cable trench and the depth of the soil, drain the water with a drainage pump, and then clean up the dirt and other debris. After the drainage and mud is cleared, the cable trays, cables and trenches in the cable trench The internal lighting and other related facilities are arranged and used normally. Records should be recorded for those that have been abnormally treated. For the arrangement of cables, the main purpose is to bridge the cables that are not arranged neatly and damaged. Fire doors, fire box, etc. should also be supplemented. 蠡 Xi County, Baoding City, Hebei Province, because it is built by the family and is a half-room, this method can meet the needs of use. The main thing is not knowing the structure of your home. If it is made of brick, it is very important to level the inside and outside plastering. It is necessary to ensure the quality and flatness, which is conducive to the construction of the room plugging process. rY Insert the matched 851 tar polyurethane sealing paste or 888 bentonite caulking glue and FUP polyurethane sealing series water-proof material into the repaired groove and fill it until the surface of the segment is flat. After the caulking is completed, it should be scraped to enhance the adhesion of the sealing paste to the concrete. The interface with the waterproof material must be free of bulging, sand, honeycombs, wood, paper scraps, sludge, small stones, and it can not be made on the loose and unstable surface, because of poor adhesion and the sun Ultraviolet rays, thermal expansion and contraction of the building itself, and water vapor pressure can easily cause aging and failure of the waterproof layer. d. Diversion and pressure relief, local water stop. Make the construction procedure conform to the water flow movement law in porous media, change from passive to active, create construction conditions that are conducive to treatment, and reduce the seepage pressure around the point. At present, due to the construction of Daxing Railway, tunnels passing through mountains, highways passing through mountains, and even sea-crossing tunnels often encounter tunnel leakage during construction. Maybe the tunnel is blocked? In your opinion, it is not necessary at the beginning because the leakage Leakage is not serious and there is no immediate huge hazard. In fact, tunnel leakage is divided into dangers. Let ’s take a look at the necessity of tunnel plugging? In the absence of tunnel plugging, the danger of continuous leakage of tunnels: Leakage in the water conveyance tunnel will not only cause the loss of water conveyance and increase the cost of water conveyance, but also cause the soil around the tunnel to collapse and form a cavity, endangering the structural safety of the water conveyance tunnel. Jg 2. PA10 polyurethane waterproof adhesive: suitable for all kinds of roofs, waterproof, 6 kg per square meter, cloth coating.
