<p> Nanning Xixiangtang District coil manufacturer specializes in king overview. The foundation pile construction of this project uses the technology of punching steel protection cylinders, drilling holes in the steel protection cylinders to form foundation pouring piles. 112 steel protection cylinders (the same number of foundation piles) need to be applied. The diameter of the steel protection cylinders is 4m, and the elevation of the top surface is 2m. The bottom elevation is determined according to the soil condition of each steel protection cylinder. , But also to meet the load-bearing capacity requirements of the facility construction platform. The piling boat is used for steel tube protection, and the pile driving efficiency is 4 per day. Inspection environment: The normal drilling in Xixiangtang District, Nanning, to a depth of 6m, using a 50T car crane to assist a 90Kw vibration hammer, the inner steel cylinder is first driven into the soil section, and then impacted to form a hole. During the construction of the sunken steel protective cylinder, the vibrating hammer must be stable and firmly welded to the top of the inner steel protective cylinder, and the plane position of the top surface of the protective cylinder must be centered to avoid the deviation of the protective cylinder due to eccentricity. At the same time, the verticality of the joints of the protective cylinders should be strictly controlled by a level ruler, which should not exceed 1/200 of the requirements of the construction code, and strive to enter the steel protective cylinders vertically. If there is a tendency to skew, correct it immediately, and eliminate the adverse factors that may occur in the bud. Quality documents are being developed to overcome the difficulty of hole formation in piles. With the development of high-rise buildings and large-span bridges, rock-socketed piles, especially large-diameter rock-socketed piles, are a special type of pile foundation. In the 1990s, it became popular. application. Rock-socketed piles have the characteristics of high bearing capacity, small deformation, and high overall rigidity. The settlement stability time is short, the settlement is small, and the seismic performance is good. Therefore, it has attracted more and more attention from engineering circles. How to construct such pile holes with high quality and economy has become the primary technical problem in the field of geotechnical drilling. The large hole diameter and high rock strength are its fundamental characteristics, which brings the following technical difficulties: The breaking work per unit volume of rock increases with the increase of rock strength, and the critical crushing force required for a single break of the rock also increases. Free answer Baoding Improving work efficiency The pile sinking machine is simple, small and convenient to transport; the pile sinking operation does not occupy a large work surface, does not affect the work in adjacent areas, and greatly improves the construction work efficiency. Fortunately, bedrock formations are prone to jamming, broken drill bits, broken drill rods, or mechanical damage due to excessive torque in the hole, which can cause personal injury or death. Coiled pipe manufacturers in Xixiangtang District, Nanning are specialized in the factors of the king. The factors include raw materials, fuel, equipment, tools, etc. In the construction of pile foundations, if the relationship between objects and objects and between objects and people are not properly handled, there are also unsafe problems. Wholesalers also have intersections in their specifications, as do their applications. Depending on the environment, what type of steel pipe is needed. Cold-rolled thick-walled coils have a wall thickness of 20mm and an outer diameter of 450-3000mm. They are rolled, welded, formed, butt-jointed, and cold-rolled thick-walled coils directly from steel plates. The processing time is short, the delivery is fast, and the cost is low. The coil is mainly used for hot rolled thick wall coils such as pipes, billboards, columns, etc. The thickness of hot rolled thick wall coils is generally greater than 20mm, and the outer diameter is 450-3000mm. The hot rolled thick wall coils are rolled under the heating of steel plates. , Welding, forming, deburring, defect detection, delivery. Sometimes the wall thickness is relatively thick and secondary heating is required. It is characterized by a small outer diameter tolerance. , Uniform wall thickness. It is important that hot-rolled thick-wall coils do not impair the performance of the raw materials. The disadvantage of thick rolls with hot rolls is the long processing time. Hot-rolled thick-wall coil is widely used: cylinder block, hydraulic pressure, bridge, roller table, etc. Let me introduce a good standard coil of steel plate. During the coiling process, the surface of the circuit board should be protected from damage. Parts with severe scarring should be ground for transition, and the wall thickness of the ground should not be less than the design wall thickness. Comprehensive quality assurance </ p> <p>

</ p> <p> The coil manufacturer in Xixiangtang District, Nanning specializes in finishing the following for the king, and after shot peening, remove the inner and outer scales of the elbow, and treat the two ends with grooves To facilitate welding. Stop the slurry plug, and fill the empty part of the slurry plug with cement slurry. Precautions for the construction of cast-in-place piles When starting drilling, the drill pipe should be kept vertical and in the correct position to prevent the enlargement of the pilot hole due to the shaking of the drill pipe and the increase of porous soil. Steel protection cylinder processing According to the diameter of the pile foundation and specifications, the steel protection cylinder is designed and processed. The steel protection cylinder is rolled by a steel plate with a thickness of 10mm, and the diameter of the protection cylinder is φ2400mm. In order to avoid local deformation caused by stress concentration at the top and bottom of the steel protective cylinder when the steel protective cylinder sinks, a 0m long and 12mm thick reinforcing hoop is added to the top and bottom of the steel protective cylinder. According to the different pile lengths, the steel protective cylinder is processed in sections, and the section processing length is between 6-12m. During the processing of the rear section steel protection tube, holes are made at the position of the tie beam, and water stop and connection treatment is performed to facilitate the construction of the tie beam. Before starting the engine in Xixiangtang District, Nanning, the safety equipment should be intact and sensitive if various regulations should be made for heavy machinery. After starting the engine, pay attention to whether the various instrument indications are normal, and then start working normally. The quality risk jacket thickness is comprehensively selected according to the jacket material, hole location hydrogeological conditions, construction and design pile diameter, jacket, burial depth and burial conditions, and should be calculated and determined if necessary. The thickness of the steel protective tube for general bored pile construction should be 6-12mm, and the reinforced concrete protective tube should be used. Coatings are usually divided into conventional coatings and heavy coatings, and are divided into chemical, physical and electrochemical coatings according to the principle. According to the different requirements of different seawater environments and projects, the operation steps of paint coating construction are the steel substrate surface treatment, primer, middle coating, and surface coating. Mechanical sandblasting is required on the steel surface. The surface treatment level is relatively high. Need to reach Sa 5 or higher. Basically, the steel pipe pile has been pre-sprayed according to the design scheme when it leaves the factory, and is basically used at the same time as cathodic protection. For the steel pipe pile under the platform of Hangzhou Bay Bridge, the coating needs to be inspected regularly every year, and the damaged area is repaired. Because the strength of the coating itself is weak, the coating is vulnerable to external physical damage, shedding, and failure. . During the repair, the surface treatment of the steel pipe is very demanding, and it is inconvenient to operate below the seawater level, and it is difficult to adhere to the surface of the steel pipe. Property rights Anhui seamless steel pipe is made of hot rolled round steel without welding. The coiled pipe manufacturer in Xixiangtang District, Nanning specializes in laying a protective tube for the king. The embedment depth should be 2 ~ 4m. In special cases, it should be deepened to ensure the smooth drilling and pouring of concrete. The inner diameter of the protective cylinder should be 20-40cm larger than the diameter of the pile. The centerline of the protective cylinder should coincide with the centerline of the pile. Unless otherwise specified in the design, the allowable error of the plane is 50mm. For the steel protective cylinder in Xixiangtang District, Nanning, the line slope is not more than 1%. This method is applicable to: The foundation of the original building does not meet the requirements due to the bearing capacity and deformation, and the foundation needs to be reinforced; the original functional requirements of the building are changed, and the induced load is increased, such as adding floors, increasing loads, rebuilding, expanding, etc. The foundation of the existing building needs to be reinforced. The foundation of the existing building needs to be reinforced due to the construction of the adjacent foundation, such as the construction of a subway, the construction of a garage, or the excavation of a nearby deep foundation pit. 2 Features of the construction method Features of the construction method are safe and reliable.

</ p> <p> The coiled pipe manufacturer in Xixiangtang District, Nanning is specialized in calculating the length of the bored cast-in-situ pile jacket. The length of the cast-in-placed pile is different depending on the construction location. Material is the main source of its stickiness. Stickiness means that the viscous tape has constant flow properties at room temperature and is sexual. The peel strength to steel is greater than 0.2N / mm, and it can be firmly attached to the surface of steel pipe piles even in water. At the same time, this characteristic gives the viscous tape excellent shapeability, can shape any shape, and can achieve self-repair of the depression on its surface. The pile driving pipe in Xixiangtang District, Nanning can also be filled. The surface of the flat steel pipe is uneven, so when the steel pipe pile is pretreated, it only needs to reach ST2 level, and it can be directly bonded to various coatings such as PP, epoxy, FB asphalt, etc. without primer, and cathodic protection. It is also fully compatible. It is a composite tape pre-coated with water-curing resin based on high-strength glass fiber fabric. As shown: the composition of the sticky marine steel pipe pile coating technology structure indicates the implementation of the sticky marine steel pipe pile coating technology implementation-the application of the Shekou Port SCT terminal structure and application area of the Shekou Port SCT terminal in Shenzhen The coating method is carried out. Before the introduction of the technology, the surface coating of the original steel pipe pile has been applied. The steel pipe pile can be seen to have obvious corrosion. The clay layer on the land is 5-2m, the sand layer or the loose soil layer and the water level are high. The soil layer with a large amount of water needs 3-4m, and the water varies from 15-30m according to different geological needs or the steel barrel is hit to a relatively stable stratum by a vibrating pile hammer. High quality and cheap impact rotary method: pneumatic / hydraulic DTH hammer drilling method; rotatable steel wire impact drill drilling method. Where good steel pipe pile is the foundation suitable for the construction of wharfs and ports, and its diameter range is generally between 600-2000mm, and it is commonly used at 1800mm. At present, doing well in China should be regarded as the limited installation of Tianjin Port and Shipping of CCCC. See below for specific information. At present, many domestic large-scale engineering piles have this share. I heard from friends that the processing capacity is quite large. It should be over 100,000 tons per year. Currently, there are two factories with an area of about 120,000 square meters. We are planning to build a larger factory with an area of 400,000 square meters in Lingang Industrial Zone in Tianjin Binhai New Area. Its scope has covered almost all seaport cities along the coast of the country, and also includes foreign places such as Africa and Oceania. The tilt angle of the steel cylinder is determined by the sensor fixed on the steel cylinder frame, and the tilt angle of the steel cylinder frame is adjusted accordingly according to the design requirements. Brief introduction of bored cast-in-place pile tube protection Here we introduce the more commonly used metal products in construction, bridges, and steel structures-bored cast-in-place tube sleeve protection refers to the use of mechanical drilling, steel pipe squeezing or manual excavation on the foundation soil at the construction site Piles are formed in the hole, and reinforced cages and concrete are placed in the piles. According to the hole formation, the piles can be divided into bored piles, immersed pipe piles and bored piles. The thickness of the protective cylinder of the project is comprehensively selected according to the material of the protective cylinder, the hydrogeological conditions of the hole position, the diameter of the construction and design pile, the protective cylinder, the burial depth, and the burial conditions, and should be calculated and determined if necessary. The thickness of the steel protective tube for general bored pile construction should be 6-12mm, and the reinforced concrete protective tube should be used. The inner viscous tape blocks water and air. The viscous tape also has the ability to isolate water and air. Compared with other commonly used strips, the water permeability is very low. The spiral steel pipe in the Xixiangtang district of Nanning is a high material and has acid and alkali resistance Capability for strong corrosion of steel pipe piles. The table is a comparison of the water permeability of different materials. </ p>
