The newly developed hollow square pile has completely overcome this disadvantage by combining centrifugal and prestressed technology with internal hollow. In the market, prestressed concrete pipe piles are used more frequently in industrial and civil buildings. They overcome the shortcomings of the previous pile types and have their own characteristics, but the disadvantages are also obvious: the appearance is smooth and round, especially when used as friction piles, the friction force with soil is small, and many projects have to use pipe piles with large outer diameter or simply use solid square piles, Increased project cost; The bending resistance of thin-walled pipe piles is poor, especially the shear resistance and tensile resistance of the pile body, which has buried hidden dangers in the foundation of the building

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. Before application, be sure to check whether each part is normal, and ensure the safety factor of each rubber hose connection. With the continuous and sustainable development trend of cement pipes and the increasing number of applications, problems such as pipeline leakage of cement pipes due to design, production and manufacturing or lack of maintenance have arisen.

1. Centerline setting of pipeline: before construction, the starting point, end point, plane break point, longitudinal break point and straight line control center pile of the centerline can be measured on the site according to the center line control point given in the design, and the direction control pile can be set at the appropriate position outside the groove of the starting point and end plane break point, and the pile number can be determined through measurement. 2. Establish temporary bench marks: temporary bench marks are often required for pipeline works, which should be set at a stable place that is not easy to be collided, and the spacing should not be more than 30 meters. The closure error of temporary benchmark shall meet the specified standards. 3. Trench excavation is mainly conducted by excavator, supplemented by manual bottom cleaning, and the connection pipe and branch pipe of rainwater hopper are excavated manually. During excavation, pay attention to the change of soil quality, and support the sections with signs of collapse.

Cement pipe drainage pipe body has many characteristics. Its heat resistance, flame retardancy and resilience are outstanding features. It is not metal but pipe. No magnetism. Therefore, when placed in the cement tank, no vortex will occur. Cement pipes can be used in many fields, such as rainwater drainage, sewage drainage, industrial wastewater drainage and community drainage. As well as the buried pipelines of highways, or for protecting cables, optical cables, etc. Then the cement pipeline has the following characteristics: 1. Generally speaking, it has rigidity, flexibility and excellent mechanical properties. And it has strong compressive properties. 2. The chemical property is stable, generally corrosion resistant, but non-toxic, and it is an excellent environmental protection pipe.

The closure error of temporary benchmark shall meet the specified standards. 3. Trench excavation is mainly carried out by excavator, supplemented by manual bottom cleaning. Rainwater bucket connecting pipes and branch pipes are manually excavated. During excavation, pay attention to the change of soil quality, and support and enclosure the sections with signs of collapse. 4. Excavate by excavator until the elevation of the trench bottom is about 10cm. Do not excavate the reserved trench bottom soil, and then remove it manually to trim the trench bottom. Manually clean the tank, carefully check the soil at the bottom of the tank for disturbance, and if there is any disturbance, special treatment shall be carried out.
