Description
Technical field
The present invention relates to and belong to colliery, iron ore, tunnel and mine tunnel engineering water hazard prediction field, specifically, relate to a kind of top board and drench water burst collection combination unit and assembly method thereof.
Background technology
Along with coal in China demand constantly rises and the exhaustion of coal resources, the coal seam of hydrogeological relative complex is obliged to go to exploit in increasing colliery.Some coal mine roadways are in digging process, and because the original mechanical balance of top board is broken, roof fracture constantly to deep expansion, is directly communicated with water producing fractures or aquifer, causes top board to occur large area trickle phenomenon.
Rig is also as easy as rolling off a log when playing anchor pole, anchor cable boring to be got through containing water producing fractures, causes anchor pole, anchor cable hole water burst serious.Top board large area trickle and anchor pole (rope) hole large discharge water burst be difficult to administer, safeguard to roadway construction and some corrosion-prone hardwares and cause very large difficulty, especially the working environment of underground labour can be worsened further, not only certain hidden danger is caused to the safety of workman, cause certain shade at heart more to underground labour, affect efficiency of construction.
In prior art, drench water burst gathering-device and method from top board and mainly contain two kinds:
One is publication number is that CN103075167A lays top board water-stop sheet or water proof cloth method, and top board trickle flows directly on water-stop sheet or water proof cloth, flows directly into gutter along coal side.Its major defect has four: 1. because closure when every block water-stop sheet or the splicing of water proof cloth is poor, complex process, top board trickle easily flows out in stitching portion, and secondary causes top board to drench water burst and flows directly into tunnel; 2. be not suitable for top board, anchor pole (rope) holes the water outlet of large area large discharge, very easily on water-stop sheet or water proof cloth, forms string bag phenomenon, to wire lath build-up of pressure; 3. water-stop sheet or water proof cloth are very easily broken in top board exterior portion by anchor pole, anchor cable, cause water proof to lose efficacy; 4. top board trickle along coal side enter gutter by directly causing side portion's anchor pole, wire lath gets rusty, and brings new potential safety hazard to tunnel.
The top board trickle collector of the second to be publication number be CN202039899U, this kind of top board trickle collector major defect has three: 1. volume is larger, not too be applicable to the working environment that down-hole coal road is narrower and small, especially the gutter of its underpart causes larger difficulty by directly to transport, pedestrian; 2. this water collector gathering-device be mainly applicable to back drenching area not quite, particularly single anchor pole (rope) to hole the situation of water outlet, to large area top board trickle because cannot combinationally use no longer applicable; 3. adopt magnet to hang on wire lath, tunnel safety hidden danger will be caused, do not meet safety of coal mines regulation.
Therefore, how to design a kind of brand-new device, solve the problems referred to above, be those skilled in the art faced by.
Summary of the invention
The object of the invention is for overcoming above-mentioned the deficiencies in the prior art, providing a kind of top board to drench water burst and collecting combination unit and assembly method thereof.This device is in down-hole and/or tunnel after installation, and the problem that water burst is collected is drenched in solution that can be good, and it is less to take construction space.
In order to reach above-mentioned purpose, the present invention adopts following technical scheme:
A kind of top board drenches water burst collects combination unit, comprising:
Trapezoidal cylinder, the top edge of this trapezoidal cylinder is provided with frange plate, and the bottom of trapezoidal cylinder is connected with flange through sleeve pipe, and flange is connected with mozzle again, and the other end of mozzle is connected with collecting pipe through threeway.
Preferably, described trapezoidal cylinder is that tin plate rolling forms.
Preferably, described frange plate is provided with multiple bolt hole.
Preferably, frange plate is also tin plate material.
Preferably, the collecting pipe that described collecting pipe connects rear least significant end by threeway or two-way is positioned at gutter.
Preferably, described mozzle and collecting pipe are pvc pipe.
Preferably, described trapezoidal cylinder is forge piece of step type structure.
Present invention also offers above-mentioned top board and drench the assembly method that water burst collects combination unit, comprise the steps:
A, trapezoidal cylinder, frange plate, sleeve pipe, flange, mozzle, threeway and collecting pipe are transported in tunnel;
B, according to be followed successively by from top to bottom trapezoidal cylinder, frange plate, sleeve pipe, flange, mozzle and threeway order assemble, form top board and drench water burst and collect combination unit, two other interface of threeway is connected with collecting pipe;
C, assemble multiple top board and drench water burst and collect combination unit, adjacent top board being drenched water burst, to collect the frange plate of combination unit overlapping, utilizes securing member that frange plate is fastening;
D, utilize two-way and/or threeway to be connected collecting pipe, the delivery port of the collecting pipe of least significant end is positioned at gutter.
The invention has the beneficial effects as follows: the present invention has the following advantages:
1, a difficult problem for back large area, large discharge pouring water burst is solved.This captation is connected between two by bottom pvc plastic conduit, pouring water burst in the most any one section of tunnel length is pooled to a place, be discharged in default gutter, portion of side, solve and the difficult problem that water burst cannot collect place discharge is drenched for tunnel large area, large discharge in the past;
2, closure is good.Multiple bolt hole is reserved with in this captation top frange plate, by bolt, the frange plate that adjacent four top boards pouring water burst collects combination unit is overlaped, so exposed at the basic no-top plate of the surrounding of this captation, top board drenches water burst and substantially all falls in trapezoidal cylinder, and sealing is also good between bottom pvc plastic pipe and threeway, overflow without the globule, solve a difficult problem for device closure difference in roof water improvement in the past;
3, reusable edible, long service life.Captation of the present invention detachably reuses, and after the top board pouring water burst in one section of tunnel terminates, this captation in this section of tunnel can be removed, when required in the tunnel being installed to another section of water outlet;
4, lane space is taken little.Captation upper design of the present invention becomes three notch cuttypes, greatly reduces device volume, and the present invention only takies very little space, top, tunnel, can not counteract effect to bottom pedestrian and transport;
5, any one section of tunnel inside ceiling panel unit area trickle amount can accurately be measured.Captation in any one section of tunnel is linked together by bottom pvc plastic pipe and pvc Three-way Union, pouring water burst in this section of tunnel is pooled to a place, namely carry out accurate measurement by corresponding measurement mechanism, solve is all the difficult problem blindly guessed by experience in the past;
6, a whole set of captation structure is simple, and be easy to processing and install, and the material that this device adopts is cheap material common on market, processing cost is low, economical rationality.
