Abstract
The invention relates to a method for treating a system on the back surface of an underground pipe gallery after water leakage; underground pipe gallery (2) are because stratum (1) differential settlement leads to misplacing between multisection underground pipe gallery (2) to form the crack, get slip casting hole (3) through boring on the wall of underground pipe gallery (2), pour into the thick liquid in slip casting hole (3), after the thick liquid solidifies connect underground pipe gallery (2) and stratum (1) of the peripheral certain limit of pipe gallery as a whole, reach and improve stratum (1) of the peripheral certain limit of pipe gallery and be the homogeneous stratum, and then weaken the differential settlement. And meanwhile, the permeable channels in the stratum (1) and the pipe gallery (2) can be sealed, and the channel for water in the stratum (1) to permeate into the pipe gallery (2) is cut off. The invention blocks the water seepage channel in the stratum (1) by the slurry, thus solving the water seepage problem from the source; and the underground pipe gallery (2) can not be cracked again in a short time.
Description
Technical Field
The invention relates to the technical field of underground pipe gallery water seepage construction, in particular to a treatment method for a backwater surface system for underground pipe gallery water seepage.
Background
The underground pipe gallery is also called as an underground city pipeline comprehensive corridor, namely a tunnel space is built underground in a city, various functional pipelines such as electric power, communication, gas, heat supply, water supply and drainage and the like are integrated, a special overhaul port, a special hoisting port and a special detection system are arranged, unified planning, unified construction and management are implemented, and the underground pipe gallery is an important infrastructure and a life line for city operation. The underground pipe gallery contains various pipelines and needs to provide a passing road for maintenance personnel. Because the underground pipe gallery is built in sections, after the underground pipe gallery is built, the settlement speeds of the underground pipe galleries are different due to different materials of foundations, different compositions below the foundations or different stresses above the pipe galleries, so that the joints of the underground pipe galleries are staggered to generate cracks; because the piping lane is located the underground, during the water infiltration that exists in the stratum reached crack department and flowed into the underground pipe gallery from the crack, the damage of piping lane interior conduit was caused easily in the piping lane infiltration to hinder maintenance personal's the current, the infiltration caused the incident more easily at the power line pipeline part. The existing maintenance method aiming at the water seepage of the underground pipe gallery is to expand the crack at the crack, cut the crack flat by a cutting tool and fill the crack by concrete so as to achieve the purpose of preventing the water seepage. However, the method cannot solve the problem of inconsistent settlement speed of the underground pipe gallery, and the newly repaired crack is a weak part and can be stretched and cracked again under the continuous settlement of the underground pipe gallery. The prior art is therefore not able to serve the purpose of preventing water penetration for a long time.
Disclosure of Invention
The invention aims to overcome the defects of the prior art and provide a treatment method for underground pipe gallery water seepage.
The purpose of the invention is realized by the following technical scheme: a method for treating a backwater surface system of an underground pipe gallery after water leakage seepage comprises the following steps:
s1, measuring the length of the sinking section of the underground pipe gallery, and determining a sinking area; the regional process that sinks that detects promptly underground pipe gallery is whole sinks for the region, sinks one section that the speed is faster for the rest of underground pipe gallery, sinks fastly and geology is more loose, exists rivers in the stratum more easily.
S2, drilling holes, namely drilling a plurality of grouting holes on the water leakage surface of the underground pipe gallery; the depth of the plurality of grouting holes requires drilling into the stratum connected with the back water surface of the underground pipe gallery.
S3, grouting, namely grouting slurry into the grouting holes to fill the gap on the back surface side of the underground pipe gallery with the slurry; the surface of a back of the body of underground pipe gallery is for being close to one side of stratum, after the thick liquid is injected, the thick liquid fills up the space of injected hole and surface of a back of the body one side, after the thick liquid solidifies, then will be with the sunken stratum connection of different speeds as a whole, make to have the effort between the stratum, through the mutual containment between the stratum, slow down the sunken relative velocity difference between the stratum, even the underground pipe gallery sinks under this condition, also sink as a whole, make the underground pipe gallery can not appear the dislocation in the short time, lead to the crack to enlarge or the crack of having repaired splits once more. And the injected slurry will simultaneously block the passage of the water flow, fundamentally preventing the infiltration of water into the formation.
S4, expanding the seam, and cutting and flattening the seam at the water leakage position by a cutting tool; the cut and leveled cracks are convenient for filling concrete, and the weak points of the cracks can be cut off by cutting the cracks, so that the newly filled concrete is stably supported.
S5, filling the crack, grouting in the cut and leveled crack, filling the space and the water seepage channel in the crack with the poured grout, completely blocking the water seepage channel at the crack after the grout is solidified, preventing the water seepage even if the crack cracks again, and then plugging the crack with concrete.
Preferably, the plurality of grouting holes are drilled in the direction of the trend of the underground pipe gallery.
Preferably, grouting holes are drilled in the underground pipe gallery wall surface of the sinking area. The wider the slurry is diffused after the whole grouting, the larger the connection range between the stratums is, the larger the interaction force between the stratums is after the slurry is solidified, and the more stable the whole stratum is.
Preferably, the underground pipe gallery wall surface comprises the wall surfaces of the left side, the right side and the upper side of the underground pipe gallery. Fill and repair the underground pipe gallery that sinks the region all-roundly, it is that all stratum around the underground pipe gallery link as an organic whole through the thick liquid, reduce the stratum and sink the speed difference, avoid underground pipe gallery's dislocation.
The invention has the following advantages:
1. the problem of water seepage is solved from the source by plugging a water seepage channel in the stratum by slurry;
2. after the poured slurry is solidified, the whole stratum is connected into a whole, so that the sinking speed of the whole stratum around the underground pipe gallery is consistent, and the repaired crack can not be cracked again in a short period even if the sinking speeds are inconsistent.
