5. On both sides of the trench and 1m above the bottom of the trench, elevation piles shall be set symmetrically, and elevation nails of equal height shall be nailed on them. The center line of the pipe channel and the elevation of the elevation pile shall be re measured before the bottom of the trench is reached and the pouring is leveled. 6. The height of soil piling on one side of the trench shall not be more than 2 meters, and the distance from the trench edge shall not be less than 1 meter. The protection of underground pipelines for trench construction shall be disclosed to the relevant departments first to clarify the basic location of underground facilities. If necessary, sample holes shall be excavated first to find out the exact location, facilitate construction, and ensure the safety of various embedded pipelines, Support protection measures shall be taken for exposed pipelines.

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.

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.

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. Cement pipes have been widely used in industrial production and urban planning and construction, and have played a key role, such as coating pipes used for drinking water, electric power engineering communication equipment, natural gas camp, etc., which must be laid underground. The quality assurance of infrastructure is the foundation of engineering construction in all big cities, so more stringent regulations must be made on the construction materials.
