Abstract
The utility model discloses a refuge chamber door wall structure in the pit, this structure includes the refuge chamber door wall and the explosion vent entrance to a cave, refuge chamber door wall is embedded in the refuge chamber wall, the position punishment that the big lane of refuge chamber wall outside refuge chamber leads to the existence room in the refuge chamber do not sets up twice refuge chamber door wall, tunnel in the middle of the twice refuge chamber door wall forms the transition room, the refuge chamber wall is embedded in the rock stratum, refuge chamber door wall is equipped with the blast pipe, the built -in prefabricated steel fibre of the refuge chamber door wall concrete slab that excels in, the steel fibre excels in and pours the high -strength concrete around the concrete slab, arrange prestressing force steel stock along explosion vent entrance to a cave radiation in the refuge chamber door wall, refuge chamber door wall, refuge chamber wall, rock stratum are passed to double -deck setting of prestressing force steel stock, with whole refuge chamber door wall structure anchor in the rock stratum, double -deck prestressing force steel stock is by drawknot steel bar connection. The utility model provides a refuge chamber door wall assault the problem that takes place structural distortion, shifts, caves in down receiving the explosion, this kind of refuge chamber door wall structure can form a whole with refuge chamber wall synergism, when downhole accident takes place, keeps apart the blast shock wave and the hazardous gas of explosion production, the personnel in messenger's accident hide the disaster safely, win the quality time for fleing for one's life in refuge chamber.
Description
Technical field
This utility model relates to mine safety rescue safety guarantee facilities and equipment technical field, particularly belongs to for underground refuge chamber door wall construction.
Background technology
Existing underground mining mine typically requires configuration to take refuge facility (refuge chamber, survival capsule, refuge), general refuge chamber is positioned near shaft station, the degree of depth has 600 to 900 meters of depths sometimes, and underground work personnel cannot flee the scene and can inside wait for rescue by temporary shelter.These facilities of taking refuge generally close space, are connected with refuge chamber Wai great lane by arranging explosion proof door wall construction.Existing refuge underground chamber door wall typically passes through concreting, owing to concrete material is the moulding material of a kind of bullet, elastic relatively small, body of wall may be made to be deformed, ftracture, cave in when blast occurs, and underground structure stress is more complicated, the country rock district connecting refuge chamber in down-hole is frequently present of stress mutation, transfer phenomena, it is easier to making explosion proof door wall be deformed by surrouding rock stress extruding, ftracture, this is the most unsafe for needing completely enclosed refuge chamber.Therefore using novel refuge underground chamber door wall construction effectively can form a rigidity entirety, synergism more preferable suitable for surrounding rock stress with whole refuge chamber wall, the design of double-deck chamber door wall is more safe and effective.
Summary of the invention
This utility model solves the problem that refuge underground chamber door wall occurs malformation under by blast impulse, shifts, caves in, this refuge underground chamber door wall construction can form an entirety with refuge chamber wall synergism, when down-hole accident occurs, isolation blast produce explosion wave and toxic and harmful, make the personnel in accident in refuge chamber safe harbor disaster, win the quality time for escape.
The technical solution adopted in the utility model is as follows:
nullA kind of for underground refuge chamber door wall construction，This structure described includes refuge underground chamber door wall and explosion proof door hole，Described refuge underground chamber door is embedded in refuge chamber wall within the walls，The position of described refuge chamber wall existence room within refuge chamber Wai great lane leads to refuge chamber is respectively provided with twice refuge underground chamber door wall，Tunnel in the middle of described twice refuge underground chamber door wall forms transition chamber，Described refuge chamber wall is embedded in rock stratum，Described refuge underground chamber door wall is provided with exhaustor，Described refuge underground chamber door puts pre-manufactured steel fiber high-strength concrete slab within the walls，Described high strength steel fibre concrete panel area pours high-strength concrete，Described refuge underground chamber door radiates arrangement prestress steel anchor rod within the walls along explosion proof door hole，Described prestress steel anchor pole bilayer is arranged through refuge underground chamber door wall、Refuge chamber wall、Rock stratum，By whole refuge underground chamber door wall、Refuge chamber wall is anchored in rock stratum，Described double-layer prestressed steel anchor rod is connected by steel tie.
This structure described includes refuge underground chamber door wall and explosion proof door hole.
Described refuge underground chamber door is embedded in refuge chamber wall within the walls.
The position of described refuge chamber wall existence room within refuge chamber Wai great lane leads to refuge chamber is respectively provided with twice refuge underground chamber door wall.
Tunnel in the middle of described twice refuge underground chamber door wall forms transition chamber.
Described refuge chamber wall is embedded in rock stratum.
Described refuge underground chamber door wall is provided with exhaustor.
Described refuge underground chamber door puts pre-manufactured steel fiber high-strength concrete slab within the walls.
Described high strength steel fibre concrete panel area pours high-strength concrete.
Described refuge underground chamber door radiates arrangement prestress steel anchor rod within the walls along explosion proof door hole.
Described prestress steel anchor pole bilayer is arranged through refuge underground chamber door wall, refuge chamber wall, rock stratum, whole refuge underground chamber door wall, refuge chamber wall is anchored in rock stratum.
Described double-layer prestressed steel anchor rod is connected by steel tie.
Compared with the prior art, the beneficial effects of the utility model are as follows:
This utility model refuge underground chamber door wall construction uses composite due to it, and intensity is high, good integrity, total cooperative bearing works, and can be effective against sudden change and the transfer of surrouding rock stress, and be not easy to be destroyed in blast, the advantages such as low cost of manufacture, technique are simple, by extensive concern.This utility model refuge underground chamber door wall construction built-in vent pipe, refuge chamber outside atmosphere can be detected, foul smell and waste gas are discharged refuge chamber, and refuge underground chamber door wall construction uses built-in pre-manufactured steel fiber concrete slab, solves bulk strength, problem that rigidity is inadequate；Use prestress steel anchor pole through refuge underground chamber door wall, refuge chamber wall, the mode of rock stratum, solve the collaborative opposing surrouding rock stress of composite, the problem of blast impulse, and the setting of double-layer prestressed steel anchor rod, solve the stability problem of composite inner.The solution of problem above can make refuge underground chamber door wall construction be used widely in down-hole.
