The key to the reinforcement structure of the rectangular pool is at each corner. Chuang 19 is several ways of horizontal steel bar arrangement at the corner of the pool wall. The general principle is to have fewer types of steel bars, to avoid excessive cross re-fragrance, room plugging, pool plugging, expansion joint plugging, plugging spot, advanced technology, excellent quality! Accept customized, direct sales. And ensure tunnel plugging Rebar anchors are the same length. Special attention should be paid to the steel bars at the corners. If it must bear the bending moment of the edge induced by the water pressure in the pool, the length of the anchor group in the bearing side should not be less than JA. In order to meet this requirement, it is often necessary to bend it into the adjacent pool. At this time, it should be bent to the compressed area, that is, outside the pool wall, and then bent into fi. If continuous reinforcement is used for the horizontal reinforcement of two adjacent pool walls, the bending method shall be adopted. It is necessary to deal with the cracks in the wall of the renovated house. Y Smoking is strictly forbidden at the construction site, and there are fire-fighting equipment on site. o Some project departments in Tianjin Binhai New Area stipulate how many tasks are completed in the contract plan, but there are no clear requirements for the consumption of materials and the use and maintenance of the equipment. It was completed, but the material cost was overrun, the performance of the equipment decreased, and the entire project lost money. For old masonry, use a wire brush or chop to remove the loose pine skin and residues until the brick surface, and rinse with water. Smoking is strictly prohibited at the construction site of E Datong. Fire protection equipment is also provided on the site. The leakage of the Yc project requires the use of mechanical drainage and dehumidifiers or dehumidifiers for dehumidification all year round, which will cause loss of energy consumption and soaring costs. Interface agent: Apply the interface agent to the wall. The interface agent must be completely brushed and evenly brushed. Financial management confusion Mn e. Grouting: After the plugging material waterproof mortar reaches a certain strength, grout from the grouting tube; judge the grouting effect according to the slurry condition of the corresponding grouting tube next to it, and strive to fill the gap and distribute uniformly; grouting pressure At 0.3-0.4MPa, it is generally determined by field test; after the grouting is completed, the grouting pipe mouth is fastened with iron wire to prevent grout; when the grout is hardened, cut the grouting pipe.

Ingredients: Mix several reagents into a group of mixed slurry, and determine the setting time of the ingredients according to the amount of water leakage. x has high self-adhesive strength, and can also be firmly adhered to other materials such as concrete, brick, rock, etc. W In order to ease the huge pressure of living in urban spaces, smart architectural designers now look at the space, and rooms, shopping malls, etc. have emerged. However, a common problem in the room is the big problem of room plugging. When it comes to the problem of room plugging, the root cause is still water. Yesterday we have briefly introduced the first part of the characteristics of room plugging. Introducing Water Characteristics Part I: The interface between the base layer and 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. The reason is Poor adhesion, coupled with the sun's ultraviolet rays, the building's heat and cold, and water vapor pressure can easily cause aging and failure of the waterproof layer. Where is J? According to different situations, you can choose the appropriate plugging plugging. But sometimes in the face of complex leakage situations, you need to use a combination of two types of plugging. Due to the crowded urban space, most residential buildings or shopping malls have begun to expand, such as modern shopping malls, subways, garages, etc., the type of space building is Huamen, and it can be found everywhere in the city. However, due to the complexity of various environmental factors nowadays, the phenomenon of unknown causes of room leaks often occurs. Today, we will briefly introduce the common reasons for plugging in the lower chamber: the reasons are complicated. Leakage of expansion joints in Tianjin Binhai New Area can be divided into hole leakage and crack leakage. From the perspective of water leakage, it can be divided into slow permeability and fast permeability. , Rapids, high pressure rapids. Hole leakage repair: When the water pressure is not large and the leaking hole is small, the "direct plugging method" is adopted. When the water pressure is large and the leaking holes are large, Tianjin Binhai New Area Plugging Company adopts the "downpipe plugging method". When the water pressure is large and the leaking holes are not large, it uses the "wood wedge plugging method". When the water pressure is large, the water leakage is serious, and when the holes are large, the "prefabricated box plugging method" is adopted. Repair of leaking cracks; when cracks with low water pressure appear, slow seepage, fast seepage or rapids can be treated by "direct plugging method". Slow seepage, fast seepage and water leakage with large water pressure are treated by "offline plugging method". The rapid water leakage with large water pressure is treated by the "lower half-round iron sheet plugging method". Leakage at the wall roots and female corners is treated by the "corner pressing method". After the leaking holes and cracks are blocked, you should use waterproof materials to make more waterproof and fruit. The daily room plugging is important and cannot be ignored, even because of the special environment in which it is located. It is recommended that you use a combination of "flexible and flexible" to prevent leakage. cF b. Cutting or drilling: Use a cutting machine to cut a seam with a depth of 6-8cm at each of the left and right sides of the seepage gap to prepare for grooving. Scratch-coating waterproof layer: follow the guidelines of detailing first and then large surface. Ha must be used for tunnel plugging. If leakage occurs, the calcium hydroxide of the reinforced concrete will be lost, and the PH value will become smaller, which will easily cause the steel bars in the concrete to rust. It will accelerate the alkali aggregate reaction of structural concrete, which will affect the structural safety and reduce the service life of the project.

Ingredients: Mix several reagents into a group of mixed slurry, and determine the setting time of the ingredients according to the amount of water leakage. Packaging strategy m Leakage of water in the project will dissolve the calcium hydroxide existing in the reinforced concrete, reduce the pH value, easily lead to corrosion of the steel bars in the concrete structure, and accelerate the alkali aggregate reaction of the structural concrete, thereby affecting The structural safety shortens the service life of the project. The caulking material in the S seam is cracked, or the sealing material filled in the deformation seam is poor in water tightness; within a width of about 20 cm on both sides of the segment joint, use a wet grinder. Eliminate uneven debris, floating dust, etc., and lay the foundation for the next step of coating waterproof coatings, plugging and grinding the fresh concrete pavement. x Cracks in Tianjin Binhai New Area: Under normal circumstances, kraft paper tape and white latex will be used to seal the cracks. dF The grouting method blocks water out of the masonry, thereby solving the problem of pool leakage. 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, tunnel leakage may still occur. 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 plugging techniques in tunnel plugging: Corrosion, perforation, leakage, leakage, leakage, etc. of the pressure-plugging pipeline container are constantly stopped and the pressure is stopped, and the fire is blocked quickly. In order to alleviate the huge pressure of living in urban spaces, smart architectural designers now look at the space, and rooms, shopping malls, etc. have emerged.
