Main structure and instruction manual of large-diameter cement pipe jacking machine - Main structure: a set of double-action hydraulic pipe jacking machine main body. One set of high-pressure pump station and one top block of electric motor pump station. One block. One track. One car was unearthed. 2. Construction method: First dig the working pit according to the size of the machine model, and then support it. If the working pit encounters soft soil or quicksand layer, support must be built around it to ensure the safety of the machine and people. After digging the working pit, first put the track into the working pit, find the correct direction along the construction route, and adjust the level. Lift the pipe jacking machine smoothly into the working pit and place it on the track. According to the needs of the pipe diameter, the clay is unearthed forward along the track, and the cement pipe is smoothly hoisted into the working pit. It is necessary to add oil to the middle of the rear end face of the cement pipe when the iron tile is buckled. Place the block horizontally at the iron tile at the rear end of the cement pipe. Start the high-pressure pumping station, and when the oil cylinder and the block push against the force, check whether the rear support is firm. After confirming that the rear support is firm, you can push the cement pipe forward. If there is silt, remove it and then push forward and so on until completion. 3. Precautions during construction: The excavation technique of clay workers is the key to smooth and accurate jacking of cement pipes. Therefore, clay workers are required to not only pay attention to safety, but also select the size and horizontal direction of clay according to the soil quality and pipe diameter. During the jacking process, the main body of the pipe jacking machine must work with the piston rod to push the cement pipe smoothly along the track. If an abnormality occurs, continue jacking after the abnormality is discharged. The back support is a very important part in the pipe jacking facility. If the back support is not firm, the jacking work cannot proceed smoothly. Therefore, strengthening the back support is very important in the pipe jacking project. It is best to use square wood for the back support. Arrange in single or double rows and pour cement if necessary. The electric pumping station needs to be equipped with a safety protection electrical box and a low-voltage line for lighting when digging out soil in a pipe. In order to ensure construction quality and safety, construction personnel must strictly abide by operating procedures and be both bold and careful to ensure the smooth progress of the project. The machine should be maintained regularly, check the machine's operating condition at any time, and solve problems in a timely manner if any problems are found. When the machine is running, the operator cannot leave the machine, and the normal working pressure cannot exceed MPa. When installing the oil pipe, you must check whether there is a rubber ring on the interface, otherwise oil will leak. Cylinder ejector stroke. The safe stroke cannot be exceeded. If the stroke is exceeded, the machine may be damaged or people may be injured. After the ejector rod is returned to its original position, the machine must be stopped. When the operating rod is returned to its original position, the machine can no longer pump oil. The supercharged machine may be damaged or injure people. Above, you must pay attention, otherwise the cylinder will break the screw and cause damage or injury. After the work is completed, the pressure relief operating lever must be pushed back and forth a few times before unloading the oil pipe, otherwise the hydraulic oil will spray out and injure people. After construction is completed, seal both ends of the oil pipe.
