Jacking equipment capable of preventing pipeline deflection

Abstract

The invention discloses jacking equipment capable of preventing pipeline deflection. The jacking equipment comprises a fixing plate, a fixing assembly and a guide sleeve in a conical structure, wherein the fixing plate is arranged on the inner wall of a deep well; a driving mechanism is arranged on the fixing plate and comprises a pressure equalizing plate; the fixing assembly is positioned at theinner bottom of the deep well and comprises a bottom plate; a vertical rod is arranged at the top of the bottom plate; an upper pressing plate and a lower pressing plate are arranged on the verticalrod; both of the upper pressing plate and the lower pressing plate are capable of moving along the direction of the outer wall of the vertical rod, and provided with arc-shaped recesses for placing apipeline; a through hole is formed in the guide sleeve in the conical structure; the pipeline is capable of penetrating through the through hole in the guide sleeve; a plurality of connecting rods arranged circumferentially are further arranged on the side wall, facing the direction of a positioning assembly, of the guide sleeve; movable rods are arranged on the connecting rods; the movable rods penetrate through the connecting rods; rollers and limiting rings are further arranged on the movable rods; the limiting rings are connected with the movable rods through threads; and the rollers are positioned on the tail ends of the movable rods and capable of rotating on the movable rods.

Description

Technical field [0001] The invention relates to a woodworking tool, in particular to a jacking device capable of preventing pipeline deflection. Background technique [0002] With the development of urban construction, the problem of water conservancy pipe network construction has become more and more prominent. Traditional slotting construction is becoming less and less suitable for urban construction due to damage to roads, impact on traffic, and environmental pollution. The construction of small-diameter drag pipes has gradually Can not meet the needs of rapid social development and urban expansion, and pipe jacking construction has effectively solved the existing problems, and has been more and more used in the construction of water conservancy pipe networks. Pipe jacking construction technology is a kind of trenchless technology for laying underground pipelines with better environmental protection. Under the condition of not disturbing or slightly disturbing the soil struct...

AI Technical Summary

Problems solved by technology

[0003] At present, when pipe jacking technology is used to install drainage pipes, when the propulsion equipment moves the pipe, due to the different soil properties of the underground soil layer, the pipe jacking process will be subjected to force through the soil layer due to the different soil properties. The phenomenon that the pipeline is offset from time to time will cause the pipeline to deviate, and it will be more troublesome to correct the pipeline in the later stage
