Problems solved by technology

[0009] Moreover, the shield excavator itself is a cylindrical excavator. In addition, as mentioned above, since the cylindrical tunnel is built by assembling blocks on the ring, when it is used inside a tunnel with a rectangular cross-section such as an underground passage, due to the circular The difference between the shape and the rectangle creates a useless part inside the tunnel that cannot be used, additional excavation is required, and additional concrete must be used, and the construction cost also increases at this time

Embodiment Construction

[0045] Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. Fig. 1 is a longitudinal sectional view showing the first embodiment of the method for constructing a tunnel by advancing an underground box body of the present invention, figure 2 is the sectional view of line A-A in Fig. 1, image 3 It is a sectional view of line B-B in Fig. 1 .

[0046] The present invention is an infinite self-advancement method, suitable for constructing tunnel-like underground buildings across these roads at positions where the cover soil layer thickness is relatively shallow, such as directly below roads or railway lines 38 .

[0047] Multiple (more than 3) concrete boxes 1 are arranged side by side, and intermediate jacks 2 are arranged between the boxes 1 .

[0048] And the front end of the box body 1 in front is equipped with cover shape knife edge 3, is provided with PC steel rope 4 as traction part to run through whole box body 1, ...

Abstract

A method for constructing tunnel by driving underground case body to advance includes installing cutting tools to front end of said case body, passing the drawing member (such as PC-steel cable) through the case body, arranging the fixing part or driving jack to the back end of case body, arranging the driving jack or fixing part at another end, and digging segment by segment.

Description

technical field [0001] The present invention relates to a method and device for constructing a tunnel by advancing an underground box, which advances a concrete box underground to construct a tunnel-like underground structure. Background technique [0002] Under the railway lines and under the highway pavement, it is necessary to build underground buildings that cross these roads underground, but the most common construction method is the so-called open-cut ditch construction method, that is, using a shovel such as a backhoe to move from the ground to the ground. Underground excavation, open excavation and ditching, constructing concrete underground buildings in the ditch by assembling formwork, setting up concrete boxes, and then backfilling with soil. [0003] However, due to digging down from the ground, the open-cut ditch construction method has to block the train operation and road traffic. On the contrary, when the train operation and road traffic are prioritized, the ...
