Abstract
The invention discloses a method and a device for solving water seepage and leakage on the surface of a lining of an underground cavern, wherein a blocking structure is adopted to block underground water by a waterproof layer arranged at the position where a concrete lining is connected with a rock wall; then the underground water above and at two sides of the concrete lining is led to drainage ditches in the concrete lining for concentrated drainage through a longitudinal blind pipe arranged outside the waterproof layer and a group of arch-shaped blind pipes longitudinally and uniformly distributed along the concrete lining. The invention utilizes the waterproof layer to effectively prevent the groundwater in the drain hole from eroding and infiltrating the underground cavern to realize the function of blocking, and then utilizes the longitudinal blind pipe to lead the groundwater in the drain hole to the drainage system in the cavern to realize the drainage function; the water seepage and water leakage phenomena on the lining surface of the underground cavern are well solved, and the good environment in the cavern in the engineering construction period and the operation period is ensured.
Description
Technical field
the present invention relates to a kind of underground chamber lining cutting surface that solves to seep water the method for leaking and device, belong to Hydraulic and Hydro-Power Engineering technical field.
Background technology
at present, the waterproof of underground plant chambers mainly arranges drain hole at crown, and drain hole is connected with cavern's bottom discharge ditch by recycling blind pipe, causes in gutter by the underground water infiltrating drain hole, and recycling underground chamber drainage system carries out ejectment.Because rock cranny, the isotonic water spot distribution randomness in crack are very large, the drain hole arranged according to array pitch between certain can not discharge the infiltration in rock mass completely, and when causing power station to be run, underground chamber inner concrete lining cutting top layer often exists infiltration, leaks.Therefore, seeping water the mode of leaking or not ideal enough in the existing underground chamber lining cutting surface that prevents, can not meet the requirement of use.
Summary of the invention
the object of the invention is to, there is provided a kind of and solve the surperficial method and device of leaking of seeping water of underground chamber lining cutting, to eliminate the infiltration of underground chamber inside lining concrete surface, the phenomenon such as to leak, the operation for power station provides good environment, thus overcomes the deficiencies in the prior art.
technical scheme of the present invention is achieved in that
a kind of surperficial method of leaking that seeps water of underground chamber lining cutting that solves of the present invention is that the method adopts the mode of stifled row's structure, is blocked by underground water by the waterproofing course being located at concrete lining and crag connecting position; And then by the longitudinal blind pipe be located at outside waterproofing course and the concentrated discharge in gutter will caused with the underground water of both sides above concrete lining in concrete lining along one group of arch form blind pipe that concrete lining is longitudinally uniform.
in preceding method, described longitudinal blind pipe top and arch form blind pipe being equipped with one group for collecting the water seepage hole of underground water, being tied with one deck outside water seepage hole for stopping the geotextiles of silt; The underground water infiltrated in longitudinal blind pipe flows into the gutter in concrete lining through arch form blind pipe nearby.
according to said method form of the present invention a kind of to solve the seep water device that leaks of underground chamber lining cutting surface be that this device comprises the waterproofing course be located at outside concrete lining; Between waterproofing course and crag gunning concrete layer, be provided with the one group of arch form blind pipe longitudinally arranged along concrete lining, one group of arch form blind pipe connects along longitudinally uniform longitudinal blind pipe through one group; Arch form blind pipe two ends are connected with the gutter being located in the ground cavern's concrete lining inner bottom part through bend pipe.
in aforementioned means, described arch form blind pipe and longitudinal blind pipe are equipped with uniform water seepage hole, outside water seepage hole, are provided with filtration beds.
in aforementioned means, described filtration beds is the geotextiles be wrapped in outside water seepage hole.
owing to have employed technique scheme, the present invention compared with prior art, under the Groundwater that the present invention utilizes waterproofing course effectively to stop in drain hole, cavern corrodes and infiltrates and realizes stifled function, recycling longitudinal blind pipe causes in the inner water drainage system of hole by the underground water in drain hole, the function of the row of realization; The infiltration well solving underground chamber lining cutting surface, the phenomenon of leaking, ensure that the good environment in construction phase of project and runtime hole.
Accompanying drawing explanation
fig. 1 is structural representation of the present invention.
being labeled as in accompanying drawing: the longitudinal blind pipe of 1-waterproofing course, 2-arch form blind pipe, 3-, 4-gutter, 5-bend pipe, 6-crag gunning concrete layer, 7-concrete lining, 8-water seepage hole, 9-filtration beds.
Detailed description of the invention
below in conjunction with drawings and Examples, the present invention is described in further detail, but not as any limitation of the invention.
a kind of method solving the infiltration of underground chamber lining cutting surface and leak of the present invention, as shown in Figure 1: the method adopts the mode of stifled row's structure, is blocked by underground water by the waterproofing course being located at concrete lining and crag connecting position; And then by the longitudinal blind pipe be located at outside waterproofing course and the concentrated discharge in gutter will caused with the underground water of both sides above concrete lining in concrete lining along one group of arch form blind pipe that concrete lining is longitudinally uniform.Longitudinal blind pipe top and arch form blind pipe being equipped with one group for collecting the water seepage hole of underground water, being tied with one deck outside water seepage hole for stopping the geotextiles of silt; The underground water infiltrated in longitudinal blind pipe flows into the gutter in concrete lining through arch form blind pipe nearby.
according to of the present invention a kind of device solving the infiltration of underground chamber lining cutting surface and leak that said method is formed, as shown in Figure 1: this device comprises the waterproofing course 1 be located at outside concrete lining 7; Between waterproofing course 1 and crag gunning concrete layer 6, be provided with one group of arch form blind pipe, 2, the one group of arch form blind pipe 2 longitudinally arranged along concrete lining 7 connect along longitudinal uniform longitudinal blind pipe 3 through one group; Arch form blind pipe 2 two ends are connected with the gutter 4 being located in the ground cavern's concrete lining 7 inner bottom part through bend pipe 5.As shown in the enlarged fragmentary portion in Fig. 1, arch form blind pipe 2 and longitudinal blind pipe 3 are equipped with uniform water seepage hole 8, outside water seepage hole 8, are provided with filtration beds 9.Filtration beds 9 is the geotextiles be wrapped in outside water seepage hole.Clean and tidy in order to drawing, only depict the signal of water seepage hole on a blind pipe and filtration beds in Fig. 1, the partial enlarged drawing of all the other each Guan Jun in Fig. 1 is identical.
