The closed pressure-bearing easily-detached brick is characterized in that the hollow brick body is of a cube shape, wherein two insulation walls are arranged in the hollow brick body, and the thickness of the insulation walls is 20mm; and holes are formed in the insulation walls, fixed bulges are respectively arranged at four corners at the upper part the hollow brick body, grooves are respectively formed in four corners at the lower part of the hollow brick body and are matched with the bulges, the thickness of a sealing wall at the upper part of the hollow brick body is 10mm, the thickness of a sealing wall at the lower part of the hollow brick body is 20mm, hollow brick body is filled with sand, one-way teeth are arranged on the outer side of the hollow brick body, and the angles of the one-way teeth are 20-45 degrees.
Description
Technical field
The present invention relates to when down-hole fire sealing, it is possible to the one readily removable fragment of brick of special pressure-bearing that Rapid Implementation is closed.
Technical background
Removing fire dam is ambulance corps when processing mine fire accident, a regular safe practice sex work.At present, each underground coal mine mostly carries out block with work stone or square brick and closes.When removing fire dam, due on market but without special instrument of decoding preferably, broken close particularly difficult；Particularly highly gassy mine, for instance: in 2005 Nian Fumei companies 3 during 217 airtight dismounting, due to what make with work stone, rescue team member when breaking seal airtight, continuous operation 12 hours, just removed, broken to close the time long, and security risk is big, affects the safety of rescue team member.When implementing to abolish airtight, key is how quickly to be beaten by fire dam to open a gap, and then quickly removes fire dam.
Summary of the invention
It is an object of the invention to the work efficiency that can improve ambulance corps when breaking seal fire dam, strengthen unpacking fire dam technical merit, make the airtight work of unpacking more quick rapidly, to achieve these goals, the technical scheme is that the mine laneway readily removable fragment of brick of airtight pressure-bearing, including hollow brick, it is characterized in that: hollow brick is cubic shaped, being provided with two dividing walls in hollow brick, the thickness of dividing wall is 20mm；Dividing wall is with porose, above four corners of hollow brick are respectively arranged with fixed lobe, four corners below hollow brick are respectively provided with fluted, groove and male cooperation, sealed wall thickness above hollow brick is 10mm, and the sealed wall thickness below hollow brick is 20mm, is provided with sand in hollow brick, hollow brick arranged outside has unidirectional tooth, the angle of unidirectional tooth to be 20 ° ~ 45 °.
Advantages of the present invention:
1, ambulance corps's work efficiency when breaking seal fire dam can be improved, strengthen unpacking fire dam technical merit, make the airtight work of unpacking more quick rapidly；
2, can reducing rescue team member's working time in disaster area, for rescue team member, in disaster area, work improves safety guarantee；
3, can shortening the time of unpacking fire dam, in the past unpacking is airtight will 4-5 hour, it is now desired to about 30 minutes just passable, produces for mine recovery and gains time, the economic benefit of raising mine, it is achieved safety and stability.
4, this mine laneway readily removable fragment of brick of airtight pressure-bearing can be directly utilized when building fire dam, the effect of work stone, fragment of brick can be played；Carrying easy to use, cost is relatively low, and work stone fragment of brick price difference is few；Save and remove the airtight time, safety guarantee is provided when removing airtight for rescue team member.
Accompanying drawing illustrates:
Fig. 1 is the structural representation of the present invention；
Fig. 2 is the structural representation of the present invention；
Fig. 3 is the structural representation of the present invention.
In accompanying drawing: 1, sand；2, unidirectional tooth；3, hole；4, fixed lobe；5, groove；6, dividing wall；7, sealed wall.
Detailed description of the invention:
Below in conjunction with Figure of description, 1 ~ 2 couple of present invention is further described:
1, size: 240mm(length) × 240mm(width) × 11mm(height)；370mm(length) × 240mm(width) × 11mm(height)；
2, bearing pressure: 20 tons；
3, square brick frame wall gauge: 10mm；Divider wall gauge: 20mm；The end: 20mm；Face: 10mm；
4, raw material composition: 425# portland cement, sand (or microlith)；Different according to intensity, cement and sand proportioning are typically chosen 1:2 or 1:3；
Charges: sand.
Three, processing technology
Production machine is utilized to be divided into three steps: to make framework 1；Carry out filling sand 2；Carry out capping 3；Then compacting forms.
Four, target is reached
When fire dam built by mine, it is possible to serve as plugging material and directly build in fire dam；When removing fire dam, directly the mine laneway readily removable fragment of brick of airtight pressure-bearing is abolished, it is possible to quickly remove fire dam, ensure the safety of rescue personnel.
Just utilize the special fragment of brick of part when fire dam starts to construct, be embedded in fire dam, implement to close.This special fragment of brick is when breaking seal airtight, it is easy to abolish, it is possible to quickly break an aperture by force by airtight, then quickly by airtight strong all dismountings.This special fragment of brick we term it: the readily removable fragment of brick of the airtight pressure-bearing of mine laneway.The readily removable fragment of brick of the airtight pressure-bearing of this mine laneway have resistance to compression, antiknock, intensity height, high temperature-proof, fire-retardant, be easy to carry, the function such as easy to use, cost is low, size according to mine sealing wall, design 240,370 two kind of model, it is easy to the construction of underground airtight wall.The readily removable fragment of brick cement of the airtight pressure-bearing of this mine laneway, sand and microlith are raw material, according to special industrial mould, make fragment of brick hollow frame, and hollow position has partition wall to be isolated into some spaces, carry out sand filling in space, and after filling, compacting forms further.
When underground construction fire dam, just can, according to the design of fire dam, airtight for the mine laneway readily removable fragment of brick of pressure-bearing be carried out airtight together with other plugging material in advance.Due to the internal sand for filling of the readily removable fragment of brick of the airtight pressure-bearing of this mine laneway, when abolishing fire dam, utilize ambulance corps's instrument just can easily by airtight dismounting in 30 minutes.Reduce the work risk of rescue team member, it is ensured that the safety of rescue personnel.
The readily removable fragment of brick of the airtight pressure-bearing of this mine laneway, has reached advanced international level, has filled up domestic blank.
