Embodiment Construction

[0035] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0036] refer to Figure 1~3 As shown, the construction method of the present invention's top-pull combination rectangular pipe jacking tunnel specifically includes the following construction steps:

[0037] S001. Determine the position of the faulty pipe jacking machine 11, such as figure 1 shown.

[0038] When determining the position of the faulty pipe jacking machine 11, measure the elevation, slope and rotation angle of the faulty pipe jacking machine 11 as the data basis for subsequent construction, and continue to track and measure during the subsequent construction process.

[0039] S002. Provide a pair of pipe jacking machines 12, such as figure 2 As shown, the starting base and guide rails of the docking pipe jacking machine 12 are arranged in the original receiving shaft 14 . Determine the jacking axis of the butt pipe ...

Abstract

The invention discloses a jacking pulling combined rectangular jacking pipe tunnel construction method. The lacking pulling combined rectangular jacking pipe tunnel construction method comprises the following steps that a the position of a fault jacking pipe machine is determined; b a butt jacking pipe machine is arranged in an original receiving well; c the butt jacking pipe machine jacks towards the fault jacking pipe machine, and the butt jacking pipe machine temporarily stops the jacking at a first set distance from the fault jacking pipe machine; d the fault jacking pipe machine is pulled back towards an original starting well for a second set distance, and the tunnel gap formed in the back pulling is reinjected while the back pulling is conducted; e when the reinjection is finished, the butt jacking pipe machine jacks forwards; f the steps from c to e are repeated until the two jacking pipe machines reach the original starting well, the two jacking pipe machines are lifted out of the well, and the tunnel is communicated through. A road surface large excavation repair fault jacking pipe machine is replaced by the jacking pulling combined rectangular jacking pipe construction through the tunnel axis line design, the back pulling rejection system, fault jacking pipe machine reform and special construction parameter set and control, influence to the surrounding environment is reduced, construction cost is saved, and construction period is shortened.

Description

technical field [0001] The invention relates to a rectangular pipe jacking method tunnel construction method in the field of engineering construction, in particular to a jacking combination method that utilizes two rectangular pipe jacking machines of the same size to realize the coexistence of inverted pulling, refilling and jacking on the measured axis Construction method of rectangular pipe-jacking tunnel. Background technique [0002] At present, the shallow buried urban road tunnels and tunnels in soft soil are mostly constructed by open-cut method, under-cut method and rectangular pipe jacking method. [0003] The open and cut construction method will lead to overturning and diversion of ground traffic, overturning and diversion of river channels, relocation of pipelines, etc., which will have a greater impact. The owner needs to coordinate more units in the early stage, delaying the construction period and increasing investment. At the same time, due to the impact of...
