Abstract
With a tunnel water-stopping structure for blind pipe, it contains splash guard and geotechnique weaves cotton cloth, waterstop, fluid sealant, band blind hole conduit, attachment fastener.When in country rock, the water-enriched layer water yield is larger, have comparatively juicy to move in lining cutting, first certain inhibition is played by the migration of water-stop sheet and geotechnological 5 pairs of underground water of weaving cotton cloth, there is the partition effect of fluid sealant 7 in addition, flow into the moisture accumulation of lining cutting in the seam of adjacent lining cutting, finally be gathered in the water in seam, by with the fixing gutter 10 with holes of attachment fastener 15, moisture is guided in the gutter 13 of orbital plane less than 1, so just make the moisture of hydrous fluids near lining cutting reduce, reduce the destruction of moisture to country rock and tunnel internal facility.The utility model can stifled, cut, on anti-basis, when the facilities such as the splash guard arranged in the early stage lost efficacy, strengthened the effect of draining by water guide blind pipe, the final water content reduced around lining cutting.
Description
Technical field
The present invention relates to a kind of waterproof/drainage structure, belong to a kind of novel tunnel guarded drainage facility.
Technical background
Keep the drying in tunnel to be make one of its essential condition normally run, but tunnel internal often there will be ground water seepage disease, especially at shrinkage joint, the position such as settlement joint, aseismatic joint is more serious.Mainly be waterproof, water blockoff for tunnel waterproof and water drainage system at present, intercept water measure, drainage measure just arranges gutter at track basifacial batter place, better can not meet the requirement keeping tunnel drying.When in country rock, underground water is more, the waterstop laid and splash guard often lost efficacy, underground water can protect through these sealings, cause and in constuction joint, to produce a large amount of underground water alluvials even enter tunnel internal through lining cutting, percolating water often causes electric leakage, corrosion of metal, at Han Qu and low temperature season, the underground water of alluvial freezes, and destroys lining cutting and ancillary facility thereof further.If build in process at tunnel lining mould, be embedded into draining blind pipe, the underflow of infiltration splash guard can be made to be guided in gutter by blind pipe, thus reduce the alluvial of underground water in constuction joint, tunnel internal is kept dry, also can alleviate the generation of freeze injury simultaneously.
Summary of the invention
The purpose of this utility model is for tunnel provides a kind of guarded drainage facility, avoids underground water to enter to be seeped within tunnel lining, causes the destruction of tunnel internal facility and liner structure further.In the place that underground water is more, after splash guard forms one waterproof measure inefficacy, by laying water guide blind pipe or guiding gutter in constuction joint, in time the underground water of alluvial in constuction joint being discharged, maintaining tunnel inner drying, ensure traffic safety.
The purpose of this utility model is achieved in that it contains that splash guard and geotechnique weave cotton cloth 5, waterstop 8, fluid sealant 7, it is characterized in that: the overall water guide pipeline also formed containing blind pipe 2 with holes or guiding gutter 14 and attachment fastener 15.Wherein, water guide blind pipe 2 is diameters is 10.0cm, length is the plastic flexible pipe of 50cm.Guiding gutter 14 is width is 10cm, and the degree of depth is 10cm, and both sides install the wide edge of a wing of the 3cm that is fixedly installed for convenience, and length is 50cm plastics guiding gutters.By being assemblied to form whole section of water guide blind pipe or guiding gutter during use, and with outside geotextiles parcel water guide blind pipe or guiding gutter after assembled completing, avoid the foreign material blocking blind holes such as sand.By prefabricated conduit pipe, the location larger to groundwater run off or rainy season, when the facilities such as the splash guard arranged in the early stage lost efficacy, to the underground water water conservancy diversion entered near preliminary bracing to gutter 13, eventually through the drainage of drainage duct, strengthen the block-water effect of tunnel water handling facility comprehensively.

Detailed description of the invention
With reference to Fig. 1 ~ Fig. 5, in the present embodiment, after supporting in the early stage 4 completes, laying water-stop sheet and geotechnique weave cotton cloth 5, are carrying out the construction of lining cutting 6, the seam crossing filling fluid sealant 7 occurred in the junction of adjacent two pieces of lining cutting in construction, and waterstop 8, and reserve at seam top or dig out drainage pipe mounting groove 10, finally the circular cross-section draining blind pipe 11 or rhone that are provided with water seepage hole 12 are placed in mounting groove, and with fastener 15, it are fixed.
Operating principle: as shown in Figures 1 to 5, when in country rock, the water-enriched layer water yield is larger, have comparatively juicy to move in lining cutting, first certain inhibition is played by the migration of water-stop sheet 5 pairs of underground water, there is the partition effect of fluid sealant 7 in addition, flow into the moisture accumulation of lining cutting in the seam of adjacent lining cutting, finally be gathered in the water in seam, by gutter 10 with holes, moisture is guided in the gutter 13 of orbital plane less than 1, the moisture of hydrous fluids near lining cutting is so just made to reduce, by the drainage of drainage, the block-water effect of comprehensive reinforcement tunnel water handling facility, reduce the destruction of moisture to country rock and tunnel internal facility.
