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.

How is Jiaxing cement pipe made? First of all, the items needed for the production of cement pipes: steel bars, fine aggregate concrete, seam slots, steam chambers, reinforced shelves, cement pipe molds. Manufacturing process of cement pipe: first bind the reinforcement of cement pipe on a shelf, then wrap the reinforcement cage with a special mold, then pour fine aggregate concrete from a slot, seal the slot, then turn on the motor, make the rotary shaft in the cement pipe run to drive the cement pipe to rotate, make the concrete gradually dense through centrifugal operation, and then put it into the steam chamber for curing, Take it out when the strength of formwork removal is reached.

4) When mixing and sinking, start the rotary table of the deep mixing pile machine. When the speed of the mixing head is normal, the drill pipe can be mixed while sinking along the guide frame. The sinking speed can be adjusted by the gear, and the working current should not be greater than the rated value. 5) When the grout is mixed and lifted and sunk to the design depth, start the mortar pump, send the grout through the pipeline to the grout outlet of the mixing head, start the mixing pile machine and tighten the chain device after the grout is discharged, and lift the drill pipe while spraying and mixing according to the designed lifting speed (0.50~0.8m/min) to fully mix the grout and soil. 6) Repeat mixing and sinking. After the mixing bit is lifted to 500mm above the pile top, turn off the mortar pump, repeat mixing and sinking to the design depth, and the sinking speed shall be in accordance with the design requirements.

The common problem of cement pipe is erosion. The erosion problem of cement pipe mainly includes crevice corrosion and corrosion. These two erosion methods belong to diffuse erosion and are not easy to be detected by inspectors. The other kind of intergranular corrosion cracking is the pipeline cracking caused by erosion and other external effects of support force and ground stress, causing huge damage. At this time, the pipeline shall be removed and replaced in time. There is also a common problem of mechanical equipment damage. This kind of damage mainly includes chisels and pits containing chisels, which is generally caused by mechanical equipment damage. External cracks are also a problem of cement pipes. These problems belong to the plan problem and can be easily detected. Peeling is a relatively serious damage condition, and perforation will lead to fracture or leakage.
