Description
Technical field
This utility model relates to coal mining field, is specifically related to a kind of mine sealing wall.
Background technology
The coal production complicated condition of China, geological conditions is various, and a large amount of coal minings are all carry out under extremely complex structural environment.Along with China's rapid economic development, energy shortage problem highlights, and promotes coal mining industry to develop rapidly, puts into production one after another in the underground coal mine of many large-scale high-yield and high-efficiencies, and the problem efficiently produced that therefore ensures safety is also following.In progress of coal mining, often it is subject to the threat of the disasters such as fire, water, coal dust, roof fall, gas.Production safety is affected, it is often necessary to set up fire dam in order to prevent spontaneous combustion of coal seam, harmful gases diffusion or gas explosion.
Fire dam building, in the UNICOM tunnel with enclosed area, the shaft production district, is used to cut off the air stream in UNICOM tunnel, prevents the isolation structures that personnel enter simultaneously.
Conventional containment wall is that brick mix structure, cement or yellow mud are wiped one's face, and its advantage is that cost is low, comprcssive strength is big.But it also has irresistible shortcoming, as: under dynamic pressure effect, very easily cracking leaks out, and construction is mainly by craft, when drift section is 5～6m2If building 6～7m2Fire dam, the time needs 4～5h the soonest；When drift section is 10m2Above, if building 12～13m2Fire dam, the time needs 8～10h the soonest, forms the material weight of fire dam simultaneously and quantity is all very big, the mine deep up to hundreds of rice for being in underground, transport extremely difficult, cause that utilization and recycle rate is unsatisfactory.And the airtight effect that substantially cannot resist gas explosion shock wave of lightweight.Therefore conventional containment wall arranges unreasonable because of it, causes needing to expend substantial amounts of human and material resources, and the engineering time is oversize, it is impossible to meet instructions for use.
Utility model content
In order to solve above-mentioned technical problem, this utility model provides a kind of mine sealing wall, and this fire dam safety is good, and resistance explosion wave performance is good, and saves human and material resources, and the engineering time is short, and construction cost is low.
The purpose of this utility model implements by the following technical programs:
A kind of mine sealing wall, bar-mat reinforcement that is identical including two structures and that be arranged in parallel, the outside of every bar-mat reinforcement is arranged with multiple reinforcing bar ladder beam in parallel successively along its width, reinforcing bar ladder beam on two bar-mat reinforcements is corresponding in turn to, two mutually corresponding reinforcing bar ladder beams are respectively connected with many Counter-pulled bolts, many Counter-pulled bolts are parallel to each other and two all corresponding reinforcing bar ladder beams are vertical, sequentially build inside by laying bricks or stones and be filled with the filling bag of building materials between two bar-mat reinforcements.
Further, the distance between two Counter-pulled bolts adjacent on two mutually corresponding reinforcing bar ladder beams is identical.
Further, described Counter-pulled bolts two ends are outwards provided with extension.
This utility model one mine sealing wall, this fire dam includes two bar-mat reinforcements, bar-mat reinforcement arranges multiple reinforcing bar ladder beam, corresponding reinforcing bar ladder beam is connected to Counter-pulled bolts, adopts the form of the internal filling bag being filled with building materials to build by laying bricks or stones simultaneously, improve the structure of conventional containment wall and build form by laying bricks or stones, effectively raise fire dam security performance and resist explosion wave performance, and saving human and material resources, the engineering time is short, and construction cost is low.
Accompanying drawing explanation
Below according to drawings and Examples, this utility model is described in further detail.
Fig. 1 is the structural representation of a kind of mine sealing wall of this utility model；
Fig. 2 is the right view of Fig. 1.

Detailed description of the invention
As shown in Figure 1-2, a kind of mine sealing wall described in this utility model embodiment, bar-mat reinforcement 1 that is identical including two structures and that be arranged in parallel, the outside of every bar-mat reinforcement 1 is arranged with multiple reinforcing bar ladder beam 2 in parallel successively along its width, reinforcing bar ladder beam 2 on two bar-mat reinforcements 1 is corresponding in turn to, two mutually corresponding reinforcing bar ladder beams 2 are respectively connected with many Counter-pulled bolts 3, many Counter-pulled bolts 3 are parallel to each other and two all corresponding reinforcing bar ladder beams 2 are vertical, sequentially build inside by laying bricks or stones and be filled with the filling bag 4 of building materials 5 between two bar-mat reinforcements 1.
This utility model is in use, according to the demand thickness of fire dam, closing place section etc., bar-mat reinforcement 1, reinforcing bar ladder beam 2 are installed, make correspondingly sized filling bag 4, be filled with building materials in the inside of filling bag 4, build by laying bricks or stones between two bar-mat reinforcements 1, and do drawing firm with Counter-pulled bolts 3, which improve the structure of conventional containment wall and build form by laying bricks or stones, effectively raise fire dam security performance and resist explosion wave performance, and saving human and material resources, engineering time is short, and construction cost is low.
Preferred embodiment, the distance between two Counter-pulled bolts 3 adjacent on two mutually corresponding reinforcing bar ladder beams 2 is identical for one, it is possible to the effective stability improving fire dam.
Simultaneously, Counter-pulled bolts 3 two ends are outwards provided with extension, Counter-pulled bolts 3 lever strength is higher than airtight body of wall, it is made up of the bidirectional fastening body of rod, the extension at its two ends can form friction (or bonding) resistance with Rock And Soil close contact, it is positioned at the extension outside body of wall and can form the Radial resistant force to body of wall, form actively pretension.
In order to save manpower further, material resources, save engineering time and construction cost, when Specific construction, can first according to the demand thickness of fire dam, close place section and bar-mat reinforcement 1 is installed, reinforcing bar ladder beam 2, make correspondingly sized filling bag 4, build by laying bricks or stones between two bar-mat reinforcements 1, and do drawing firm with Counter-pulled bolts 3, then building materials is selected further according to user demand, it is mixed the building materials being formed uniformly liquid, and the building materials of liquid is pumped in filling bag 4 by filling, complete to build by laying bricks or stones after material solidification, filling bag 4 can be made difformity and model according to tunnel specification and construct requirement to adapt to tunnel.
This utility model one mine sealing wall, for the isolation between mine, exploiting field, the main air entering and returning of coal-face or the closing to exploiting field and flame range, this fire dam safety is good, resist explosion wave performance good, and saving human and material resources, engineering time is short, and construction cost is low, it is easy to promote the use of.
Last it is noted that the foregoing is only preferred embodiment of the present utility model; it is not limited to this utility model; for a person skilled in the art; technical scheme described in foregoing embodiments still can be adjusted by it; or wherein portion of techniques feature is carried out equivalent replacement; all within spirit of the present utility model and principle, any amendment of making, equivalent replacement, improvement etc., should be included within protection domain of the present utility model.
