Abstract
The invention relates to an underground cavern drainage blind ditch device and a construction method. A plurality of circular small holes are arranged on the wall of a rubber tube, and are arranged in a plum blossom mode or rectangularly along the length direction of the wall of the rubber tube; water filtering geotextile and waterproof geotextile wrap the outer wall of a joint of the rubber tube and a three-way or four-way rubber tube, one side, which is wrapped by the water filtering geotextile, of the rubber tube clings to a water seeping rock wall, and the other side, which is wrapped by the waterproof geotextile, of the rubber rube is far away from the water seeping rock wall; the rubber tube wrapped with the geotextile is fixed on a rock surface by stainless steel fixing clamps; the fixing clamps are mounted at intervals ranging from 20cm to 40cm; and two ends of each fixing clamp are nailed on the rock surface by drive pins. Construction is convenient, efficiency is high, construction procedures of a rubber drainage blind ditch are few, construction quality is reliable, a drainage effect is good, and the rubber tube has certain flexibility and can be laid along a water seeping belt of the rock wall closely. Seeped water can be ensured to be drained into an appointed drainage open ditch or a water-collecting well along the rubber drainage blind ditch.
Description
Technical field
The invention belongs to the Hydraulic and Hydro-Power Engineering technical field, be specifically related to a kind of underground chamber weeper drain device and job practices.
Background technology
At present, the weeper drain of water conservancy and hydropower underground chamber adopts the plastics french drain, and the plastics french drain can not well contact with the infiltration crag, and joint location is difficult fixing, is difficult to the drainage effect that reaches good; Plastics french drain fitting operation is inconvenient in addition.
Summary of the invention
The present invention has overcome the weak point that existing underground chamber weeper drain adopts the plastics french drain; A kind of weeper drain material of cheap, easy for installation, reliable construction quality is provided, improves efficiency of construction, reduce construction cost, guarantee the drainage effect of underground chamber weeper drain thereby reach.
Technical scheme of the present invention is: on the rubber tube tube wall, open several circular apertures; Circular aperture is blossom type or square type layout along the tube wall length direction; Rubber tube and threeway or four-way rubber tube connector outer wall parcel drainage type geotextile and waterproof type geotextile; The side that rubber tube is being wrapped up in the drainage geotextile is close to the infiltration crag, and a side of wrapping up in waterproof geotextile is away from the infiltration crag; Be fixed on the rubber tube of wrapping up in geotextile on the scar with the stainless steel fixed card, whenever a fixed card be installed, follow closely the fixed card two ends on scar with nailing at a distance from 20～40cm.
The present invention and prior art relatively have the following advantages: constructing operation is convenient, efficient is high; The rubber tube cutting is simple; Rubber tube outer wall parcel geotextile is easy to operate, follows closely the fixed card two ends on scar through the ail gun nailing, thereby is fixed on the rubber weeper drain on the crag.Rubber weeper drain working procedure is few, technology is simple, only needs two people just can carry out operation; The reliable construction quality drainage effect is good, and rubber tube has certain flexibility, can be close to crag infiltration band and lay.In addition, the side that rubber tube is being wrapped up in the drainage geotextile is close to the infiltration crag, and a side of wrapping up in waterproof geotextile is away from the infiltration crag, and can guarantee to seep water is discharged to the open drain or the collecting well of appointment along the rubber weeper drain.It is bonding that rubber weeper drain joint connects the employing all-purpose adhesive, and adhesive effect is good.Adopt the stainless steel fixed card to be fixed on the rubber weeper drain on the crag fixation, difficult drop-off.
