Abstract

The utility model provides a hole and fissure water drainage device. A main body is a double-layer round pipe with holes, internal threads are arranged at the left end of the double-layer round pipe, external threads are arranged at the right end of the double-layer round pipe, the inner pipe wall and the outer pipe wall are wound with stainless steel wire meshes and wrapped by anticorrosion screen meshes, and quartz sand uniform in grain size is filled between two pipes of the double-layer round pipe. The double-layer round pipe and the quartz sand filled in the middle have good permeability. The hole and fissure water drainage device has the functions of water drawing, water seeping, water draining and blockage preventing.

Description

The unrestrained device of a kind of hole-crevice water

Technical field:

The utility model relates under a kind of double-porosity model condition, the unrestrained device of mine water.

Background technology:

Characteristics such as it is little that the coal measure strata sandstone pores-the crack water outlet has permeability, and the water seepage time is long, and EXIT POINT is many, and the tunnel is under the mutual effect of water petrofacies often cause that roadway surrounding rock is softening, Surrounding Rock Strength sharply reduces, and roadway support is produced adverse influence.

Be to reduce hole-crevice water to the emollescence of roadway surrounding rock, must instant unrestrained hole-crevice water, the unrestrained water hole of site operation is naked hole at present, and along with the prolongation of unrestrained time, naked hole country rock occurs softening, and cause collapsing hole, plug-hole affect unrestrained effect.For this reason, need research a kind of unrestrained sandstone pores-crevice water device, avoid above-mentioned accident to occur.

The utility model content:

The purpose of this utility model provides the unrestrained device of a kind of hole-crevice water, the generation of avoid collapsing hole, plug-hole accident.

The apparatus main body that the utility model provides is double-deck pipe with holes.

Above-mentioned double-deck pipe is tied with stainless steel cloth at inside and outside tube wall, twines anticorrosion silk screen outward.

Fill the uniform quartz sand of particle diameter in the middle of the above-mentioned double-deck pipe.

Said apparatus is threaded connection.

Pipe in this device can effectively be avoided the hole that collapses; The quartz sand triplen of double-deck pipe and middle filling has good permeability, can play draw water, infiltration, hydrophobic and prevent the effect of stopping up; The silk screen tool corrosion resistance of most external parcel, and prevent that the fine graineds such as flour sand, mud from entering in the unrestrained hole, thus effectively prevent the plug-hole phenomenon.

The utility model is simple in structure, the hole-crevice water in can effective unrestrained porous media, thus avoid the generation of roadway surrounding rock ruckbildung.

Description of drawings:

Fig. 1 is the utility model three-dimensional structure diagram.

Fig. 2 is the utility model sectional drawing.

Fig. 3 is the utility model job site figure.

Among the figure: the double-deck pipe of 1-; The 2-internal thread; The 3-external screw thread; 4-internal layer pipe; The outer pipe of 5-; 6-quartz sand; The 7-sieve aperture; The 8-stainless steel cloth; The anticorrosion silk screen of 9-; 10-boring; The 11-aquifer; The 12-sleeve pipe.

The specific embodiment:

Below in conjunction with description of drawings the utility model performance.

The unrestrained device of the utility model hole-crevice water, main body are the double-deck pipe 1 with sieve aperture 7, and its left end has internal thread 2, and right-hand member has external screw thread 3.Double-deck pipe 1 is comprised of internal layer pipe 4 and outer pipe 5, is tied with stainless steel cloth 8 on the inside and outside tube wall, and wraps up with anticorrosion silk screen 9.Fill the uniform quartz sand 6 of particle diameter in the middle of the double-deck pipe 1.By screw thread, many pipes can connect from beginning to end.

The utility model constructure scheme is: in roadway construction boring 10, behind the pore-forming, a plurality of above-mentioned pipe 1 head and the tail are connected, make its length and relative rich water aquifer 11 water exit end equal in length, then connect the sleeve pipe 12 that does not have sieve aperture, make pipe 1 just be positioned at water exit end, then boring is installed firmly.Hole-crevice water enters pipe by the double-layer tube wall sieve aperture, and flows out along pipeline, thereby has reduced the emollescence of hole-crevice water to roadway surrounding rock.

Claims

1. unrestrained device of hole-crevice water, it is characterized in that: main body is double-deck pipe with holes, and its left end has internal thread, and right-hand member has external screw thread.

2. device according to claim 1 is characterized in that: described double-deck pipe, be tied with stainless steel cloth at inside and outside tube wall, and with anticorrosion silk screen parcel.
