The shape of square pile is easier to develop a non welded quick connector, which can truly achieve all-weather construction, and construction is faster, which can avoid cracking of welded pile head in high groundwater level. 1) Positioning, centering and leveling of the pile driver. After the mixing pile position is placed, move the mixing pile driver to the designated pile position, centering and leveling (leveling with a level). 2) Adjust the verticality of the guide frame, and use a theodolite or plumb bob to control the verticality of the guide frame in both directions. According to the design and specification requirements, the verticality is less than 1.0% of the pile length. 3) The slurry is premixed in advance. While the deep mixer is premixing and sinking, the cement slurry is mixed in the background and put into the aggregate hopper before grouting. The cement grade 425 # ordinary silicate cement is used to mix the slurry, the water cement ratio is controlled in the range of 0.45~0.50, and the cement consumption per meter of deep mixing pile is not less than 50Kg according to the design requirements.

7) The grout is repeatedly stirred and lifted. After sinking to the design depth, the grout is repeatedly stirred and lifted until it reaches the ground. 8) The pile driver is moved. After the construction of one pile, move the pile driver to the next pile position, and repeat the above steps for the construction of the next pile. Jiaxing cement pipeline, also known as cement pressure pipe and reinforced concrete pipe, can be used as sewer pipe in urban construction, sewage drainage, flood control and drainage, as well as water supply pipes and farm motor wells used in some special factories and mines. Generally, it is divided into: plain end reinforced concrete cement pipe, flexible rebated reinforced concrete cement pipe, socket reinforced concrete cement pipe, F-shaped steel socket cement pipe, plain end ring joint cement pipe, rebated cement pipe, etc.

Before the cement pipe is laid down, the elevation of the pipe top shall be controlled with a level gauge. The pipes shall be arranged from low to high. The pipes shall be placed in place and then corrected manually with excavator. The socket and spigot shall face the upstream direction, and the inner wall of the socket and spigot shall be coated with washing water, so that the rubber ring can slide in smoothly when inserting pipes and facilitate installation. In addition, the cement pipes passing the installation inspection shall be backfilled immediately, and the pipes with larger specifications shall be backfilled to at least one time the pipe diameter above the pipe top to ensure that the cement pipes can avoid directly loading the ground pressure. After backfilling, the ground shall be cleaned. In this way, the laying of a cement pipeline can be completed, and a complete underground pipeline system can be officially put into use, making its due contribution to the environmental protection construction of the city.

The theoretical calculated shear resistance of square pile is 2-3 times of that of the same pipe pile. According to the actual test of Japan's Ministry of Construction, it is 4.5 times of that of the pipe pile. This shows that the seismic performance of hollow square pile is very superior, and it is worth popularizing in earthquake prone areas, high-rise buildings, and building foundations with large areas of basements; The hollow square pile inherits and develops the low construction damage rate of the original concrete square pile. The high-strength concrete with a square head has better impact resistance than the pipe pile, and a much smaller damage rate of the pile head; The square has a larger welding perimeter than the round, fully ensuring the effective welding strength between each section of the pile, greatly reducing the joint desoldering or displacement of the square pile during construction, and making the pile quality better
