Assembled jacking pipe relaying intermediate

Abstract

The invention relates to an assembled jacking pipe relaying intermediate. According to the assembled jacking pipe relaying intermediate, bottom plates and oil cylinder activating and locating boxes are mounted at the middle of an outer shell body of the relaying intermediate, the two ends of the oil cylinder activating and locating boxes are respectively in contact connection with a front bottom plate and a rear bottom plate, the front bottom plate and a concrete pipe section are connected together in a contact manner so as to support relay oil cylinders and provide counter force for the relay oil cylinders; the rear bottom plate and a concrete pipe section are in contact connection with each other; and the relay oil cylinders are mounted in the activating and locating boxes. Due to the oil cylinder activating and locating boxes, after a jacking pipe runs through, the dismounting of the relay oil cylinders is facilitated, the intra-pipe cutting is avoided, the generation of a lot of smoke and dust is avoided, the operation is safe and fireproof, and the dismounted relay oil cylinders can be reutilized. Compared with the existing traditional jacking pipe relaying intermediate, the assembled jacking pipe relaying intermediate is different in structure and mainly formed in a manner that the activating and locating boxes are assembled, relay rings are manufactured by directly using the prolongation of steel bushings of the concrete pipe sections, no other additional components exist, each oil cylinder corresponds to each activating and locating box, a sealing device can be replaced online, the cost is low, the performance is reliable, and the mounting / dismounting is convenient.

Description

technical field [0001] The invention relates to a pipe jacking relay room for building construction, in particular to an assembled pipe jacking relay room. Background technique [0002] In the pipe jacking construction, the pipe jacking relay room is a very important link, especially in the long-distance pipe jacking construction. In the long-distance pipe jacking project, the relay room is generally used , the relay room technology is one of the key technical measures to overcome the huge jacking force of long-distance jacking construction. Due to the maturity and wide application of intermediate technology in pipe jacking construction, the pipe jacking method has been developed rapidly, and a large number of large-diameter and long-distance pipe jacking projects have emerged. [0003] Due to the unpredictability of pipe jacking, there are many random factors affecting the jacking force. For the sake of safety, the design of relay rooms is usually conservative at present, ...

AI Technical Summary

Problems solved by technology

[0004] The present invention is to provide an assembled pipe jacking relay room, which is used to solve the problem that the existing pipe jacking relay room adopts an all-steel structure, and the production cost is relatively high. It is not easy to cut and dismantle oil cylinders, and the slow speed of dismantling affects the construction period. There are fire safety hazards and a large amount of smoke will pollute the air in the pipeline, which will affect the health of the cutting construction workers. It is difficult to replace the sealing device on-line and other technical problems.
