Abstract
The utility model discloses a kind of device solving the infiltration of underground chamber lining cutting surface and leak, 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.Under the Groundwater that the utility model utilizes waterproofing course effectively to stop in drain hole, cavern corrodes and infiltrates and realizes stifled function, recycles longitudinal blind pipe and 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.
Description
Technical field
the utility model relates to a kind of device solving the infiltration of underground chamber lining cutting surface and leak, and belongs 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.
Utility model content
the purpose of this utility model is, a kind of device solving the infiltration of underground chamber lining cutting surface and leak is provided, 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.
the technical solution of the utility model is achieved in that
it is of the present utility model that 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 utility model compared with prior art, under the Groundwater that the utility model 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 utility model.
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 utility model is described in further detail, but not as to any restriction of the present utility model.
the utility model seeps water constructed by the method for leaking according to following a kind of underground chamber lining cutting surface that solves, 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 utility model 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.
