Abstract
The utility model relates to a rubber drainage blind drain device for an underground chamber. A plurality of round small holes are formed in the wall of a rubber pipe, the cross section of the rubber pipe is of an isosceles trapezoid, a line of round holes are distributed in the wall of an upper downside pipe, the pitch of holes is 8 centimeters, three arrays of round holes are distributed in the wall of a lower downside pipe, the array pitch is 4 centimeters, the pitch of holes is 8 centimeters, two arrays of round holes are respectively distributed in the walls of two waist side pipes, the array pitch is 4 centimeters, the pitch of holes is 8 centimeters, and the outer walls of the rubber pipe and a three-way or four-way rubber pipe joint are wrapped by a water filtration type geofabric and a water-resistant geofabric. A rubber drainage blind drain has less construction processes, is simple in technology and has reliable quality and a good drainage effect, and the rubber pipe has certain softness and can be laid close to the soaked zones of rock walls, and the rubber drainage blind drain device can ensure that seep water can flow along the rubber drainage blind drain to be discharged into a designated open drain or a water collecting well.
Description
Technical field
The utility model belongs to the Hydraulic and Hydro-Power Engineering technical field, is specifically related to a kind ofly install for underground chamber weeper drain (trapezoidal cross-section).
Background technology
At present, the weeper drain of water conservancy and hydropower underground chamber adopts plastic blind-ditch, and plastic blind-ditch and infiltration crag can not good contacts, and joint location is difficult for fixingly, is difficult to the drainage effect that reaches good; The plastic blind-ditch fitting operation is inconvenient in addition.
Summary of the invention
The utility model has overcome the weak point that existing underground chamber weeper drain adopts plastic blind-ditch, a kind of weeper drain device of cheap, easy for installation, reliable construction quality is provided, thereby reaches the drainage effect that improves efficiency of construction, reducing construction cost, assurance underground chamber weeper drain.
The technical solution of the utility model is: open several circular apertures at the rubber tube tube wall, the rubber tube section is isosceles trapezoid, upper base side pipe wall cloth is put row's circular hole, the side pipe wall cloth of going to the bottom is put three row's circular holes, two waist side pipe walls are respectively arranged two row's circular holes, rubber tube and threeway or four-way rubber tube connector outer wall parcel drainage type geotextile and waterproof type geotextile.
The utility model has the following advantages compared with the prior art: constructing operation makes things convenient for efficient high, the rubber tube cutting is simple, rubber tube outer wall parcel geotextile is easy to operate, by the ail gun nailing fixed card two ends is followed closely on scar, thereby the rubber drainage french drain is fixed on the crag.Rubber drainage blind ditch construction operation is few, technique 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, is wrapping up in a side of waterproof geotextile away from the infiltration crag, and can guarantee to seep water is discharged to open drain or the collecting well of appointment along the rubber drainage french drain.It is bonding that rubber drainage french drain joint connects the employing all-purpose adhesive, and adhesive effect is good.Adopt the stainless steel fixed card rubber drainage french drain to be fixed on the crag fixation, difficult drop-off.
