Description
Technical field
The utility model is related to coal mine construction technical field, more particularly to a kind of pitshaft water-tight device.
Background technology
When digging vertical in colliery, it is usually that down explosion is excavated from ground, borehole wall supporting is carried out with concrete.At present only
It is to carry out supporting with concrete, compression strength is low, and because pit shaft geological conditions is complex, if concrete shield goes out
Infiltration phenomenon just occurs in existing crack, the borehole wall, influences the use of pit shaft.
Utility model content
The purpose of this utility model there is provided a kind of pitshaft water-tight device, and compression strength is high, and can effectively prevent
The only infiltration phenomenon of country rock, security is good.
The technical solution adopted in the utility model is as follows：
A kind of pitshaft water-tight device, including outer concrete layer, cotton fibriia layer, cement expanded perlite layer and interior mixed
Solidifying soil layer, the outer concrete layer is built by laying bricks or stones on pit shaft matrix, and outer concrete layer madial wall sets cotton fibriia layer, cotton fibriia
Several shaft orientation reinforcing ribs are set, and shaft orientation reinforcing rib is fitted together on outer concrete layer madial wall, in the cotton fibriia layer in the middle of layer
Layer sets cement expanded perlite layer, and the inner side of cement expanded perlite layer sets inner concrete layer.
The reinforcement, which is uniformly distributed, to be fitted together in outer concrete layer inner peripheral.
The reinforcement is made of bamboo bar.Bamboo bar, is not afraid of tide, will not burn, and has good waterproof, fire line
Can, anti-folding, bending strength is high.
The reinforcement is provided with 8.
The utility model is in construction, after explosion terminates, and vertical concrete blinding is propped up in pit shaft matrix, is close to template outer wall
If laying dried layer cotton fibriia, the vertical reinforcement of branch in the middle of the cotton fibriia layer after laying, then in cotton fibriia layer and pit shaft
Casting concrete forms the outer borehole wall between matrix, then removes concrete blinding, is smeared plus suitable quantity of water on the inside of cotton fibriia layer
Cement expanded perlite, after dry, vertical concrete blinding is propped up again in pit shaft matrix, in concrete blinding and cement and expanded treasure
Inner concrete is poured between pearl rock and forms the interior borehole wall, construction is finished.
Compared with the prior art, the beneficial effects of the utility model are as follows：
Pitshaft water-tight device of the present utility model, compression strength is high, and can effectively prevent the infiltration phenomenon of country rock,
Security is good.By setting cotton fibriia layer in outer concrete layer madial wall, when there is the excessively outer concrete layer of water penetration, into linen-cotton
During fibrous layer, water runs into cotton fibriia and absorbed, and cotton fibriia absorbs water and sends out and rise, and the gap of external concrete layer is filled out
Fill and seal, so as to reach waterproof effect；Several shaft orientation reinforcing ribs are set in the middle of cotton fibriia layer, and shaft orientation reinforcing rib is chimeric outside
On concrete madial wall, the overall construction intensity of mine shaft is greatly enhanced；The cotton fibriia layer internal layer sets cement and expanded
Pearl rock stratum, improves fire resisting, acid and alkali-resistance effect.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.

Several shaft orientation reinforcing ribs 5 are set in the middle of flaxen fiber layer 2, cotton fibriia layer 2, and shaft orientation reinforcing rib 5 is fitted together in the outer inner side of concrete layer 1
On wall, 2 internal layer of the cotton fibriia layer set mixed in cement expanded perlite layer 3, the inner side setting of cement expanded perlite layer 3
Solidifying soil layer 4；The reinforcement 5, which is uniformly distributed, to be fitted together in the outer inner peripheral of concrete layer 1；The reinforcement 5 uses bamboo bar
It is made, bamboo bar is not afraid of tide, will not burn, there is good waterproof, fire protecting performance, anti-folding, bending strength is high；The reinforcement 5
Provided with 8.
The utility model is in construction, after explosion terminates, and vertical concrete blinding is propped up in pit shaft matrix, is close to template outer wall
If laying dried layer cotton fibriia, the vertical reinforcement of branch in the middle of the cotton fibriia layer after laying, then in cotton fibriia layer and pit shaft
Casting concrete forms the outer borehole wall between matrix, then removes concrete blinding, is smeared plus suitable quantity of water on the inside of cotton fibriia layer
Cement expanded perlite, after dry, vertical concrete blinding is propped up again in pit shaft matrix, in concrete blinding and cement and expanded treasure
Inner concrete is poured between pearl rock and forms the interior borehole wall, construction is finished.
Pitshaft water-tight device of the present utility model, compression strength is high, and can effectively prevent the infiltration phenomenon of country rock,
Security is good.By setting cotton fibriia layer in outer concrete layer madial wall, when there is the excessively outer concrete layer of water penetration, into linen-cotton
During fibrous layer, water runs into cotton fibriia and absorbed, and cotton fibriia absorbs water and sends out and rise, and the gap of external concrete layer is filled out
Fill and seal, so as to reach waterproof effect；Several shaft orientation reinforcing ribs are set in the middle of cotton fibriia layer, and shaft orientation reinforcing rib is chimeric outside
On concrete madial wall, the overall construction intensity of mine shaft is greatly enhanced；The cotton fibriia layer internal layer sets cement and expanded
Pearl rock stratum, improves fire resisting, acid and alkali-resistance effect.
