Embodiment 1

[0029] Please refer to figure 1 , figure 2 and image 3 As shown, a kind of high-speed rail and subway tunnel leakage water repair process provided by the embodiment of the present invention includes:

[0030] Judging the current water leakage situation of high-speed rail and subway tunnels;

[0031] According to the situation of water leakage, corresponding repair methods are adopted to repair the water leakage; among them:

[0032] When it is judged that the water seepage situation is water seepage in the segment splicing joint 1, the repair method of deep water stop and shallow layer reinforcement is adopted to repair the water leakage.

[0033] When it is judged that the leakage water is water gushing from segment joint 1, the repair method of curtain consolidation, deep water stop and shallow reinforcement is adopted to repair the leakage water.

[0034] When it is judged that the water leakage is water leakage from the bolts of the segments, the repair method of str...

Embodiment 2

[0057] The device obtained through the above design can basically solve the problem of water leakage at the segment joints and segment bolts of high-speed rail and subway tunnels. To carry out repairs, in line with the purpose of further improving its functions, the designer further perfects the repair system. For brief description, for the parts not mentioned in this embodiment, reference may be made to the corresponding content in Embodiment 1.

[0058] refer to figure 2 and Figure 4 As shown in Fig. 1, when water gushing occurs in segment joint 1, the repair method of curtain consolidation, deep water stop, and shallow reinforcement is adopted. Curtain consolidation includes the following steps: filling soil into the soil cavity 6 on the outside of the segment 3, and then using cement-water glass double slurry 61 formed by cement slurry and water glass slurry to pass through the plum blossom grouting pipe 7 to the soil cavity 6 Perform double liquid grouting, and final...

Embodiment 3

[0064] The device obtained through the above design can basically solve the problem of water leakage at the joints of the high-speed rail and subway tunnel segments and the segment bolts. For the purpose of further improving its functions, the designer further improved the repair system. For brief description, for the parts not mentioned in this embodiment, reference may be made to the corresponding content in Embodiment 1.

[0065] refer to Figure 5 As shown, when there is a chipping angle in the segment 3, the following steps are also included after step S19 or step S26:

[0066] S31. Chisel the concrete at the chipped corner of the segment until it is dense. For example, use steel chisels and hammers to manually chisel out the loose concrete, and it is required to chisel out a new section, and no loose concrete blocks are allowed to remain.

[0067] S32. Rinse the chipped part of the segment with clean water.

[0068] S33, using an interface treatment agent to harden t...

Abstract

The invention provides a high-speed rail and subway tunnel leakage water repairing system and a process thereof. The process comprises the steps that the current leakage water condition of a high-speed rail and subway tunnel is judged; according to the leakage water condition, a corresponding repairing method is adopted for repairing leakage water; when that the leakage water condition is segmentsplicing joint water leakage is judged, a repairing method of deep water stopping and shallow reinforcing is adopted for repairing the leakage water; when that the leakage water condition is segment splicing joint water gushing is judged, a repairing method of combining curtain solidification, deep water stopping and shallow reinforcing is adopted for repairing the leakage water; and when that theleakage water condition is segment bolt part leakage water is judged, a repairing method of structural blocking is adopted for repairing the leakage water. According to the high-speed rail and subwaytunnel leakage water repairing system and the process thereof, corresponding waterproof and leakage-stopping schemes are determined according to different leakage water parts, a plurality of materials and a plurality of processes are combined, and the problem of segment leakage water of the high-speed rail and subway tunnel is systematically solved.

Description

technical field [0001] The invention relates to the technical field of construction engineering, and in particular to a water leakage repair system for high-speed rail and subway tunnels and a process thereof. Background technique [0002] Water leakage in high-speed rail or subway tunnels is currently the most common engineering defect in the field of tunnel engineering at home and abroad. During the operation of high-speed rail or subways, if the water leakage problem is not properly dealt with, it will not only directly affect the durability of the tunnel structure, but may also As a result, related equipment and facilities in the tunnel have been damaged to varying degrees, seriously affecting the normal operation of high-speed rail and subways, and even driving safety hazards in severe cases. After on-site investigation and analysis, the leaking parts are mainly the splicing joints and anchor bolts of tunnel segments. 2. The shoe plate squeezes the water-stop strip of ...
