Abstract
The invention discloses the supporting construction that shaft of vertical well passes through the old dead zone in coal seam, belong to vertical supporting field；The technical problem to be solved is that being filled after providing a kind of Shaft Linings to shaft of vertical well, top plate and bottom plate are reinforced, prevent back and two from helping the supporting construction destroyed, be caving；Solve technical solution that the technical problem uses for：Shaft of vertical well passes through the supporting construction of the old dead zone in coal seam, and wall seat is increased newly in the excessively mined out section base slab stability rock stratum of vertical；It crosses empty well wall and wall seat and supporting is poured into a mould using armored concrete, work stone pier is set in goaf, the dead zone between work stone pier and the borehole wall carries out grouting filling to roof absciss layer area using slabstone slurry placement using high molecular bonding material；It the composite can be widely applied to vertical supporting field.
Description
Technical field
Shaft of vertical well of the present invention passes through the supporting construction of the old dead zone in coal seam, belongs to vertical support technology field.
Background technology
Existing shaft of vertical well passes through the old dead zone in coal seam, generally using drain hole draining and excludes pernicious gas, wedge of driving piles
Advance support is carried out, anchor net is studied and walling crib backboard carries out gib, pouring reinforcement concrete arch carries out permanent support, simultaneously
Carry out grouting behind shaft or drift lining, prevent the borehole wall from water drenching occur, but the top plate in old dead zone tunnel is not reinforced, after Shaft Linings dead zone not into
Row filling causes back and two to help the phenomenon that appearance is destroyed, is caving in construction more, has made shaft of vertical well and constructed
Can not be according to normal supporting in engineering, supporting is not in place, be easy to cause safety accident.
Invention content
The invention overcomes the deficiencies of the prior art, and provides being filled after a kind of Shaft Linings to shaft of vertical well,
Top plate and bottom plate are reinforced, prevent back and two from helping the supporting construction destroyed, be caving.
In order to solve the above-mentioned technical problem, the technical solution adopted by the present invention is：Shaft of vertical well passes through the old dead zone in coal seam
Supporting construction, including wall seat, work stone pier, grouted anchor bar and concrete, wall seat is arranged on the stabilization rock stratum below seat earth
On, work stone pier is arranged in coal seam goaf, and grouted anchor bar is disposed on roof absciss layer area, carries out bolt grouting,
Shaft wall and wall seat are poured using concrete；
Work stone pier is 3m ~ 5m apart from shaft wall outer distance, and the goaf between work stone pier and shaft wall carries out
Filling.
Reinforcing bar is provided in the shaft wall, the concrete Quan labels are not less than C30, the Concrete Thick
It spends for 50mm.
Goaf filling between the work stone pier and shaft wall uses slabstone mortar.
Roof absciss layer area's slip casting uses high molecular bonding material.
Pre-buried drainpipe is provided between the shaft of vertical well wall seat and work stone pier.
The present invention has the advantages that compared with prior art.
The 1st, work stone pier is set in goaf, work stone pier and the borehole wall outer distance are 3 ~ 5m, while work stone pier with
Borehole wall outer goaf is filled, and increases stability and safety of the tunnel in old dead zone.
2nd, grouted anchor bar is set in roof absciss layer area, to roof delamination area slip casting high molecular bonding material, increases
The stability of top plate, prevents roof caving, convenient for construction, increases safety.
Description of the drawings
The present invention is described further below in conjunction with the accompanying drawings.
Fig. 1 is the structural diagram of the present invention.
Fig. 2 is the structure diagram of wall seat.
1 it is wall seat in figure, 2 be work stone pier, 3 be grouted anchor bar, 4 be concrete, 5 be roof delamination area, 6 is mined out
Area, 7 be bottom plate, 8 be stablize rock stratum, 9 be pre-buried drainpipe, 10 be slabstone mortar, 11 be shaft wall.
Specific embodiment
As shown in Figure 1 and Figure 2, shaft of vertical well of the present invention passes through the supporting construction of the old dead zone in coal seam, including wall seat 1, work stone wall
Pile 2, grouted anchor bar 3 and concrete 4, wall seat 1 are arranged on the stabilization rock stratum 8 of 7 lower section of seat earth, and work stone pier 2 is arranged on
In coal seam goaf 6, grouted anchor bar 3 is disposed on 5th area of roof absciss layer, carries out bolt grouting, shaft wall 11 and wall
Seat 1 is poured using concrete 4, and work stone pier 2 is 3m ~ 5m apart from shaft wall outer distance, to work stone pier 2 and vertical
Goaf 6 between the borehole wall 11 is filled, and reinforcing bar is provided in shaft wall 11, and the 4 Quan labels of concrete are not low
In C30,4 thickness of concrete is 50mm, and the filling of goaf 6 between work stone pier 2 and shaft wall 11 uses piece
Stone sand slurry 10,5 slip casting of roof absciss layer area uses high molecular bonding material, shaft of vertical well wall seat 1 and work stone pier 2 it
Between be provided with pre-buried drainpipe 9.
In the use of the present invention, being symmetrical arranged wall seat 1 in stabilization rock stratum 8 below seat earth 7, wall seat 1 uses steel
Reinforced concrete pours, and disclosed broken, soft coal body rock mass is taken down, and carries out gib using anchor net, carries out
It constructs in next step, the setting work stone pier 2 in the goaf 6, work stone pier 2 is 3m ~ 5m apart from 11 outer of shaft wall distance, wall
The height and thickness of pile are adjusted according to field condition, and the dead zone between work stone pier 2 and shaft wall 11 uses slabstone
Mortar 10 is filled, and the borehole wall is poured using armored concrete, and borehole wall surface uses gunite concrete strengthening supporting, together
When reduce ventilation resistance, strength grade of concrete is not lower than C30, thickness 50mm, and anchor is carried out in roof absciss layer area 5
Bar slip casting injects high molecular bonding material, the rock in roof delamination area 5 is bonded, and prevents destruction and slump, influences construction peace
Entirely, the safety of shaft of vertical well is increased.
The embodiment of the present invention is explained in detail above in conjunction with attached drawing, but the present invention is not limited to above-mentioned implementations
Example, within the knowledge of a person skilled in the art, can also make under the premise of present inventive concept is not departed from
Go out various change.
