Description
Technical field
The present invention relates to water hole protection technique field, specifically a kind of drain hole protects equipment.
Background technology
During shaft construction, the drain hole of pit shaft is critically important, and especially pit shaft blows out drain hole in preceding and discharge refuse
Protection.When there is sluicing hole plug, it is necessary to take open-work measure rapidly.Some existing coal mines are put into using self-control reinforcing bar
In drain hole, prevent from blocking drain hole with broken spoil when discharge refuse because blowing out.This kind of measure, although a degree of can prevent
Sluicing hole plug, but its blocking-proof result is unsatisfactory, and also it is inconvenient.
Invention content
In order to overcome the disadvantages of the above prior art, the present invention provides a kind of pit shaft drain hole protection equipment, can be effective
Pit shaft sluicing hole plug is prevented, and easy to operate.
The present invention is realized with following technical solution：A kind of pit shaft drain hole protection equipment, including lid is laid one's hand on, it is complete to lay one's hand on lid
Cover pit shaft drain hole；The upper surface for laying one's hand on lid is equipped with protection cap；The center for laying one's hand on lid and protection cap is equipped with preformed hole, preformed hole
It is interior to be equipped with core pipe, it lays one's hand on and is uniformly provided with reinforcing rib in the core pipe of lid lower section；The upper end of core pipe is equipped with upper end cover, the lower end peace of core pipe
Equipped with bottom end cover, a steel wire penetrating core pipe is pierced by from upper and lower end cap, and the both ends of steel wire rope are equipped with clamp.
The beneficial effects of the invention are as follows：This equipment is put into drain hole, effectively prevents broken spoil from blocking drain hole；Knot
Structure is simple, easy to operate.
Description of the drawings
Fig. 1 is schematic structural view of the invention；
Fig. 2 is the vertical view of Fig. 1；
Fig. 3 is mounting structure schematic diagram of the present invention.
In figure:1, core pipe, 2, drain hole, 3, steel wire rope, 4, protection cap, 5, lay one's hand on lid, 6, reinforcing rib, 7, clamp.
Specific implementation mode
As shown in Figure 1, a kind of pit shaft drain hole guard method, including lid 5 is laid one's hand on, lay one's hand on the drain hole that pit shaft is completely covered in lid 5
2；The upper surface for laying one's hand on lid 5 is equipped with protection cap 4；The center for laying one's hand on lid 5 and protection cap 4 is equipped with preformed hole, and core is equipped in preformed hole
Pipe 1 lays one's hand on and is uniformly provided with reinforcing rib 6 in the core pipe 1 of 5 lower section of lid；The upper end of core pipe 1 is equipped with upper end cover, the lower end installation of core pipe 1
There are bottom end cover, a steel wire rope 3 to be pierced by from upper and lower end cap across core pipe, clamp 7 is equipped on the steel wire rope outside upper and lower end cap.
By taking Tang Kou coal industrys Co., Ltd south downcast project as an example, drain hole is Φ 325X12mm.The lid of laying one's hand on is
Circle is made of the steel plate of δ 30mm × Φ 350mm；The protection cap is circle, the steel plate of δ 50mm × Φ 330mm；Institute
The a diameter of 159mm for the preformed hole stated；The reinforcing rib uses length 400mm, the steel plate of thickness 30mm, the reinforcement
There are four muscle, is welded in core pipe, using two-sided welding, improves welding quality, welding uses 506 welding rods.The core pipe is adopted
With diameter 159mm, length is the drill collar of 9m.Steel wire rope uses Φ 30mm steel wire ropes.Clamp uses ingot card, is conveniently operated.
The present invention installs as shown in figure 3, drain hole protection process is as follows：
1, lid installation is laid one's hand on
Drain hole installs drain hole after disclosing and lays one's hand on lid immediately, is directly inserted after laying one's hand on lid decentralization to working face by secondary hoisting gear
Enter in drain hole, encased the floral tube part of core pipe and exposing with one section of conveyer belt, binding is secured, prevents blasting impact by broken cash
In stone access aperture.
2, the height control of tapping pipe
Within the scope of 2.5m, it is 0.4m that drain hole is exposed away from clear bottom working face for the clear high control of bottom section every time when normal driving,
Snubber drilling arrangement is determined with the hole site that sluices when drilling every time.
3, sluice protection of pipe when the clear bottom of working face
After the completion of the clear basic skill or training of working face makees, drain hole is laid one's hand on into lid using secondary hoisting gear and is pulled out, gas cutting drain water circuit sluices
Pipeline height is controlled in 300mm-400mm（Drain water circuit is suitable for reading apart from face height after gas cutting）Between.Secondary hoisting gear will
It lays one's hand on lid decentralization to be inserted directly into drain hole, be encased the floral tube part of core pipe and exposing with one section of conveyer belt, binding is secured, prevents
Blasting impact will be in broken spoil access aperture.
4, sluice protection of pipe when working face is levelling
After the completion of the levelling work of working face, drain hole is laid one's hand on into lid using secondary hoisting gear and is pulled out, gas cutting drain water circuit sluices
Pipeline height is controlled in 300mm-400mm（Drain water circuit is suitable for reading apart from face height after gas cutting）Between, secondary hoisting gear will
It lays one's hand on lid decentralization to be inserted directly into drain hole, carries out borehole wall concrete casting and constructing.
