Bored cast-in-place pile has strong vitality because of its high bearing capacity and adaptability to complex geology. However, this pile type needs to deal with the mud pumped out during construction, which causes serious environmental pollution. It has been less used in urban construction at home and abroad, and its production cost is quite high, so it is relatively less used in general industrial and civil buildings. The advantages and disadvantages of precast concrete square piles have been described, which will not be repeated, but it is worth mentioning that its construction damage rate is very low, which is also one of the starting points for our development and production of prestressed hollow square piles; At the same time, because it is solid and has a large dead weight, cracks often appear on the pile body during construction, resulting in poor durability of the pile

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.

Before the cement pipe is laid in the ground, professionals should check whether the cement pipe is in good condition and whether there are cracks. Small cracks can be repaired on the spot. If large cracks affect the construction safety, return to the factory and replace the qualified cement pipe. The foundation for pipeline laying must be strictly controlled. The cement pipe manufacturer shall be responsible for the construction and the quality department shall supervise the construction. The problems must be checked layer by layer. The problems shall not be buried underground, otherwise, the quality will directly affect the later construction, and further maintenance will consume more human and material resources. When laying the pipeline, the manufacturer's construction team shall strictly follow the construction scheme, and shall not change the construction scheme or cut corners without authorization, otherwise the hidden dangers of engineering quality left after laying will be seriously affected.

The center of gravity of the lifting object shall be properly selected, and the power generating point of the electric jack shall be effectively selected. The bottom edge must be paved, and the standard of hard and soft pavement shall be fully considered. Whether to pad the tough wood, whether to place it stably, and avoid weight depression or skew. If the residual oil of the pump body is not enough, the pump must be filled with oil during operation before application. The application of electric oil pump must refer to the manual of electric oil pump. In case of use, the requirements in the key main parameters should be followed very well. Do not be overweight. After arriving at the travel arrangement, pressure should be applied. Otherwise, when the height width ratio of lifting or the lifting tonnage exceeds the requirements, the top of the hydraulic cylinder may have serious oil leakage.

Principle of intercepting tank method: in the sewage drainage system, the intercepting tank is used to block the substances that are easy to deposit in the sewage, so as to prevent pipe blockage caused by the reduction of pipe slope and flow rate, so as to reduce the value of smaller planned flow rate and smaller planned slope of the cement pipe as appropriate, so as to reduce the buried depth of the cement pipe. During detailed planning, ordinary septic tank can be used as interception tank. Since the intercepting tank mainly blocks the easy sediment in the sewage and does not need anaerobic fermentation to purify the sewage, the volume of the sewage part can be taken as 1/3 of the normal septic tank, while the volume of the whole intercepting tank is about 1/2 of the normal septic tank.

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.
