Embodiment Construction

[0019] Below by embodiment and in conjunction with accompanying drawing, the present invention will be further described:

[0020] A method for quickly dismantling tunnel lining concrete, comprising the following steps:

[0021] Step 1, making an automatic circumcision trolley.

[0022] Such as figure 1 — figure 2 As shown, the automatic circular cutting trolley is mainly composed of a traveling mechanism 1, a stand 2, a wall saw machine 3, an arch support frame 4, an arc track 5, a horizontal jack 6, and a vertical jack 7.

[0023] The traveling mechanism 1 is arranged under the stand 2, and is used to realize the automatic walking of the automatic circumcision trolley. The rail trolley can be used as the running mechanism below the stand 2, and the automobile with rubber tires can also be used as the running mechanism. The stand 2 can be stretched left and right and up and down, and the trolley used in the tunnel can usually be stretched left and right and up and down i...

Abstract

The invention discloses a rapid tunnel lining concrete dismounting method. The rapid tunnel lining concrete dismounting method comprises the following steps that an automatic ring cutting trolley is manufactured; the automatic ring cutting trolley enters an existing disease tunnel in a contraction state, and the automatic ring cutting trolley is in an unfolded state after arrival; a saw web is arranged on a wall sawing machine, the wall sawing machine is started to conduct deep cutting and ring-direction cutting, and the cutting depth cannot be smaller than the thickness of the tunnel lining concrete; after cutting is finished, the automatic ring cutting trolley restores to the contraction state, and the saw web on the wall sawing machine is dismounted; the automatic ring cutting table moves forwards, and longitudinal cutting of the next position is conducted at the interval of one section of distance in the tunnel mileage direction; and after complete cutting is finished, dismountingof the tunnel lining concrete is conducted. The wall sawing machine is applied to an arc track of the walking track, three motors are combined to make the saw web rotate, go deep and walk along the arc track correspondingly, rapid tunnel lining concrete dismounting is achieved, the rapid tunnel lining concrete dismounting method is initiated, and wide application and popularization prospects are achieved.

Description

technical field [0001] The invention relates to the technical field of tunnel construction methods, in particular to a method for quickly removing tunnel lining concrete. Background technique [0002] Due to various reasons, diseases and problems in operating tunnels occur from time to time, and the typical situation is that the cracking of lining concrete needs to be removed and repaired in time. However, due to the high strength of the lining concrete, it brings certain difficulties to the demolition project. At present, the commonly used method is to use blasting or mechanical pneumatic pick to destroy, but the efficiency is low and the safety risk is great. Contents of the invention [0003] In view of the above technical problems, the present invention aims to provide a method for quickly removing existing tunnel lining concrete with defects, so as to improve construction efficiency and ensure construction safety. [0004] For this reason, the technical solution ado...
