Description

TECHNICAL FIELD

[0002] Pipe jacking construction is a trenchless construction method, which is a pipe laying construction technology without or with less excavation. The pipe jacking construction is to overcome the friction between the pipe and the surrounding soil by means of the jacking force generated by the jacking equipment in the working pit, and to push the pipe into the soil according to the designed slope, and to transport the earth. After one section of pipe is pushed into the soil layer, the second section of pipe is lowered to continue jacking. The principle is to use the thrust force between the main jacking cylinder and the pipe and the relay to push the tool pipe or the tunneling machine from the working pit through the soil layer to the receiving pit. The pipe is buried between the two pits after the tool pipe or the tunneling machine.

[0003] The concrete drainage pipe refers to the pipe made of concrete or reinforced concrete, which is used for conveying fluids such as water, oil and gas. It can be divided into plain concrete pipe, ordinary reinforced concrete pipe, self-stress reinforced concrete pipe and prestressed concrete pipe.

[0004] In the pipe jacking construction process of the concrete drainage pipe, two sections of pipes are usually connected by hoisting equipment and sliding rail equipment in the starting pit, and then jacking equipment is used to press and push into the soil. The connection of the two sections of pipes relies too much on hoisting operation, and the sliding rail equipment is easily deformed due to the long-time bearing of the pipe, which causes the misalignment of the two sections of pipes, increases the difficulty of the connection of the two sections of pipes, and increases the connection time of the two sections of pipes in the actual pipe jacking construction process, thereby increasing the construction period of the pipe jacking.
