Embodiment 1

[0029] Embodiment 1: A guide device for a group of rectangular tunnels that adopts pipe jacking close-fitting construction, including the following steps:

[0030] 1. Combine image 3 and Figure 4 Explain that a guide device for a group of rectangular tunnels of the present invention adopts pipe jacking construction closely, including guide female grooves 1-1, 1-1', guide male tenons 1-2, and guide female grooves 1-1, 1-1' It is made of channel steel, and the guide male tenon 1-2 is made of steel plate. The contact end of the guide male tenon 1-2 and the guide female groove 1-1 are polished into a smooth convex surface, and the guide female groove 1-1, 1 -1'The cavity is filled with sealing grease 1-6, which plays a waterproof role;

[0031] 2. If image 3 As shown, the guide trough 1-1 and the guide trough 1-1' are respectively pre-buried at the design positions of the rectangular pipe section 1-3 of the preceding tunnel and the rectangular pipe section 1-4 of the followi...

Embodiment 2

[0036] The present invention is further specifically described below with Embodiment 2. Embodiment two comprises the following steps:

[0037] 1. Combine Figure 7 Illustrate that a rectangular tunnel group of the present invention adopts a guide device for pipe jacking construction, including a guide trough 2-1, a guide male tenon 2-2, and the guide trough 2-1 is made of a steel plate. A reinforcing plate 2-5 can also be provided on the top, and the reinforcing plate 2-5 is connected to the inside of the groove of the guide trough 2-1. The reinforcing plate 2-5 is made of long iron blocks, and the guiding male tenon 2-2 Made of steel plate, the guide male tenon 2-2 and the contact end of the guide trough 2-1 are polished into a smooth convex surface, and the cavity of the guide trough 2-1 is filled with sealing grease 2-6 to play a waterproof role;

[0038] 2. If Figure 7 As shown, the guide trough 2-1 is pre-embedded at the design position of the rectangular pipe section...

Abstract

The invention belongs to the field of underground construction, and in particular relates to a guiding device for pipe-jacking close contact construction of rectangular tunnel groups, mainly solves the technical problems that during the pipe-jacking close contact construction process of the rectangular tunnel groups, the guiding is not easy to control, and the construction precision is low, and provides the guiding device for pipe-jacking close contact construction of the rectangular tunnel groups. The guiding device mainly consists of a guiding female groove and a guiding male tenon, the guiding female groove is arranged at the outer side wall of a rectangular pipe section of an existing tunnel, and the guiding male tenon is arranged on the outer side wall of a rectangular pipe section of a following tunnel close attaching to the existing tunnel by pre-burying and is located at a position corresponding to the guiding female groove, a fixed walking gap is kept between the rectangular pipe section of the existing tunnel and the rectangular pipe section of the following tunnel during the process that the guiding male tenon on the rectangular pipe section of the following tunnel slides forwards at the inner part of the guiding female groove in a matching manner. By adoption of the guiding device, the technical problems that during the pipe-jacking close contact construction process of the rectangular tunnel groups, the guiding is not easy to control, and the construction precision is low are solved.

Description

technical field [0001] The patent of the present invention belongs to the field of underground engineering, and in particular relates to a guide device for a group of rectangular tunnels that adopts close-fitting construction of pipe jacking. Background technique [0002] With the deepening of people's utilization of underground space, especially urban underground space, more and more underground engineering construction technical problems need to be solved urgently. When two or more tunnels with rectangular cross-sections are constructed at the same time with pipe jacking and close-fitting construction is required, they are generally constructed in a certain order. tunnel". In order to prevent damage to the preceding tunnel structure during the construction of the subsequent tunnel, it is necessary to strictly control the deviation of the tunnel centerline. The conventional control method is generally realized by controlling the attitude of the pipe jacking equipment, but ...
