Problems solved by technology

[0003] However, in long-distance or ultra-long-distance pipe jacking construction, when re-jacking is required, it is difficult to push because of the high friction between the long-distance pipe jacking and the inner wall of the soil layer, and it will be difficult to advance the construction at this time

Embodiment Construction

[0034] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0035] A kind of F-type reinforced concrete trunk pipe jacking, refer to figure 1 As shown, it includes a front shell 1 and a rear shell 2 coaxially arranged, the front shell 1 is plugged with the front top pipe, the rear shell 2 is socketed with the rear top pipe, and the front shell A plurality of hydraulic cylinders 3 are arranged between the body 1 and the rear shell 2. During the construction process, a relay pipe jacking is provided at intervals of multiple jacking pipes, so that after the long-distance laying of the jacking pipes, the front shell 1 The hydraulic cylinder 3 between it and the rear shell 2 pushes the front jacking pipe forward, and then the external jacking cylinder pushes the rear jacking pipe forward, thereby resetting the hydraulic cylinder 3, thereby avoiding After the long-distance jacking pipe is laid, it is difficult to push the ...

Abstract

The invention discloses an F type reinforced concrete intermediate jacking station jacking pipe. The F type reinforced concrete intermediate jacking station jacking pipe comprises a front housing anda rear housing which are coaxially arranged; the front housing is in plug-in fit with the rear housing; a plurality of hydraulic cylinders are arranged between the inner parts of the front housing andthe rear housing in the circumferential directions of the front housing and the rear housing; the two ends of the hydraulic cylinders are connected with the front housing and the rear housing correspondingly; oil inlet pipes communicate between oil inlet ports of the adjacent hydraulic cylinders; and oil outlet pipes communicate between oil outlet ports of the adjacent hydraulic cylinders. By means of the F type reinforced concrete intermediate jacking station jacking pipe, a jacking pipe can be smoothly jacked forward step by step in long-distance jacking pipe construction.

Description

technical field [0001] The invention relates to the technical field of pipe jacking construction, in particular to an F-shaped reinforced concrete intermediate pipe jacking. Background technique [0002] The pipe jacking construction technology is a non-excavation underground pipeline laying construction technology that uses hydraulic pressure as the power to jack the pipe jacking machine and the pipe joints to be laid underground one by one until the pipe jacking receiving well. It has the advantages of high construction precision, wide application of soil quality, wide range of applicable pipe diameters, low construction cost, and small impact on the surrounding environment. With the acceleration of urbanization in my country, pipe jacking technology is widely used in urban water supply and drainage, gas, electric power, communication and other underground pipe networks, as well as road and railway tunnel construction. [0003] However, in long-distance or ultra-long-dist...
