Cement pipe jacking machine open pipe jacking machine for hydraulic engineering construction

Bazhou Tongda cement pipe jacking machine main structure and operation manual I main structure: 1: a set of double acting hydraulic pipe jacking machine main body
2: One set of high-pressure pump station (motor pump station) 3: one top block
4: One stop
5: One track
6: One unearthed car
II
Construction methods: 1
First dig the operation pit according to the size of the model, and support it after going to jail
If the operation pit meets soft soil or quicksand layer, support it around to ensure the safety of the machine and personnel
2: After digging the operation pit, first put the track into the operation pit, align the direction along the construction route and adjust the level
3: Lift the pipe jacking machine into the operation pit stably and put it on the track
4: According to the pipe diameter, the clay shall be excavated forward along the track direction, 2
5m and 2
8m 5: the cement pipe shall be stably lifted into the operation pit
6: Fasten the iron tile on the rear end face of the cement pipe (add hemp in the middle)
7: Place the stopper horizontally at the iron tile at the rear end of the cement pipe
8: Start the high-pressure pump station and check whether the rear support is firm when the oil cylinder and stop are forced
After confirming that the rear support is firm, push the cement pipe forward
If there is silt, push it forward after removal, and so on until completion
III
precautions in construction 1
The excavation technology of clay personnel is the key to the smooth and accurate jacking of cement pipe
Therefore, clay personnel are required to not only pay attention to safety, but also select the size and horizontal direction of clay according to the soil and pipe diameter
2
During the jacking process, the main body of the pipe jacking machine must be jacked along the track smoothly with the piston rod, jacking block and cement pipe
In case of any abnormality, continue the jacking after the abnormality is discharged
3
The rear support is a very important link in the pipe jacking facilities
If the rear support is not firmly made, the jacking work cannot be carried out smoothly
Therefore, strengthening the rear support is very important in the pipe jacking project
The rear support * * is 200mm & mdash; 300mm square timber shall be arranged in a single row or double rows, and cement pouring is required if necessary
4
The electric pump station shall be equipped with a safety protection electric box and another 36V low-voltage line (for lighting during soil excavation in the pipe)
5 in order to ensure the construction quality and safety, the construction personnel must strictly abide by the operating procedures, bold and careful, so as to ensure the smooth progress of the project
6 pay attention to the maintenance of the machine, check the operation of the machine at any time, and solve the problems in time
7 when the machine is running, the operator cannot leave the machine, and the normal working pressure cannot exceed 6 MPa
8 when installing the oil pipe, check whether there is rubber ring at the interface, otherwise there will be oil leakage
9
Cylinder ejector rod (stroke 1
1m)
The safe travel shall not exceed 1
05 meters
After exceeding the travel, the machine will be damaged or injured
10 after the ejector rod returns to its original position, the machine must be shut down and the operating rod returns to its original position (the machine can no longer pump oil for pressurization)
The machine will be damaged or hurt people
Attention must be paid to the above 9 and 10, otherwise the oil cylinder will break the screw and damage or hurt people
12 after the work is completed, the pressure must be relieved before unloading the oil pipe (just push the operating rod back and forth), otherwise the hydraulic oil will spray out and hurt people
13 seal both ends of the oil pipe after construction
