Abstract
The utility model discloses a kind of tunnel assembled air sac sealing block wall, main body is made up of pre-cast concrete block, filled with air bag on periphery, main body wall lays temperature monitoring hole, gas monitor hole, water quantity monitoring hole from top to bottom, connected between cement block with joinery and its construction, intake valve, air outlet valve and air gauge are connected on air bag.Cement block used in the utility model main body wall can pour pre-formed in factory, therefore be not take up construction site and save material, green, efficiency of construction is high, saves the duration, and reusable edible is cost-effective.
Description
Technical field
The utility model belongs to mining equiment, a kind of tunnel assembled air sac sealing block wall.
Background technology
In mineral industry, after exploiting field exploitation terminates, oxidation of coal poisonous high-temperature gas can be produced because more than in goaf, for a long time
Coal spontaneous combustion tendency can be increased by being contacted with oxygen, and under action of underground, goaf tunnel easily produces to existing block wall
Moderate finite deformation destroys, and cracks, weakens the seal of block wall, adds the insecurity of coal production.
Utility model content
For existing laneway plugging in technical problem, the purpose of this utility model existing for closure operation and plugging effect
It is：Solve that the laneway plugging wall closure activity duration is long, the weak problem of non-deformability, entered by designing joinery and its construction pre-cast concrete block
Row splicing operation, has saved blocking time, and main body wall outside is filled the gap between tunnel with air bag, maintains main body wall
Seal.To achieve these goals, the utility model adopts the following technical scheme that：
A kind of tunnel assembled air sac sealing block wall, including pre-cast concrete block, air bag, gas monitor hole, temperature monitoring
Hole, water quantity monitoring hole, standby monitoring holes, air gauge, air outlet valve, intake valve.
Described block wall wall is made up of pre-cast concrete block, is obstructed between pre-cast concrete block by joinery and its construction splicing
Gluing knot forms.
Described air bag is made up of toughness air bag, and for filling the gap between block wall wall wall, air pressure can be by
Air outlet valve and air inlet valve regulation.
Described gas monitor hole, temperature monitoring hole, water quantity monitoring hole, standby monitoring holes are interior in pre-cast concrete block in advance
Cloth.
Advantageous effects of the present utility model are：
Using the tunnel assembled closure wall device of above-mentioned technical proposal, simple in construction, easy to process, introducing this device makes
With rear, the closure activity duration is shortened, oxidation of coal is alleviated, improves the overall non-deformability of block wall, substantially improve
Underground work environment, saves cost, the different degrees of generation for avoiding unsafe incidents, improves site safety quality water
It is flat.
