In the application of cement pipe, after the electric jack is used to jack in the lifting object, the supporting point of the lifting object shall be fixed with the support column immediately to avoid using the electric jack as the support column. 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.

In the existing market, cast-in-place pipe sinking piles, precast concrete piles, bored cast-in-place piles and prestressed concrete pipe piles are widely used. Among the above pile types, prestressed concrete pipe piles are widely used due to the advantages of factory prefabrication, high concrete strength, convenient construction, and fast cycle, while cast-in-place pipe sinking piles are difficult to ensure their quality due to the need for on-site production, Due to serious environmental pollution, it is not suitable for geological conditions with thick soft soil layer, which is prone to necking, and the construction period is very long, so it has gradually been eliminated by the market. For example, the Guangdong Provincial Construction Commission has clearly stipulated that the use of immersed cast-in-place piles is not allowed, and the Zhejiang Provincial Department of Construction has also restricted the use of immersed cast-in-place piles.

The bending resistance of thin-walled pipe piles is poor, especially the poor shear resistance and tensile resistance of the pile body, which has buried hidden dangers in the foundation of the building. Therefore, some national prestressed concrete pipe pile research meetings have clearly sent out information that the shear resistance and tensile resistance of pipe piles should be specified, and pipe piles should be carefully used in key projects, At the meeting, various experts demonstrated and looked forward to the pile type with square or polygonal external surface, hoping that China could move closer to the western developed countries and develop the foundation pile material with polygonal or variable diameter external surface. The prestressed concrete hollow square pile was developed for this purpose.

Another is artificial intervention, which is called macro-control in economics. This is mainly the measures taken by relevant government departments when the commodity price fluctuates greatly during this period. Just like buying a house a long time ago, the house price is too high for most people to afford, so the government may need to take measures to regulate the house price to return it to a normal curve. Another possibility is monetary policy, which is mainly due to the fact that the central bank has carried out some regulation against the situation of too intense price fluctuations.

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. Cement pipes have the following characteristics: 1. Generally speaking, they have 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. 3. For the connection, as long as the flexible rubber ring is used, the street seal can work well. Long term operation. High quality, no leakage 4. The inner wall of the pipeline is flat and yellow, and the fluid friction is relatively small. If used on the ground, the service life will exceed 20 years.

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.
