Description

A kind of resistance to compression waterproof fireproofing fire dam

Technical field

It the utility model is related to security technology area, and in particular to a kind of resistance to compression waterproof fireproofing fire dam.

Background technology

It is well known that in mine working engineering construction, the disaster such as gas, coal dust, top plate, fire, water is to influence tunnel peace The subject matter used entirely, to prevent spontaneous combustion of coal seam, harmful gases diffusion, gas explosion, mine water disaster etc. from influenceing production safety, Usually need to establish fire dam, can timely and effectively construct closed structure be influence one of mine safety operation it is main because Element.

Fire dam building is in the UNICOM tunnel of shaft production area and enclosed area, in order to cut off air circulation and be forbidden Pedestrian and the isolation structures being open to traffic.Traditional fire dam is brick mix structure, and pseudo-ginseng or four or eight are built by laying bricks or stones with common brick, cement or yellow mud Brick wall, although the cheap compression strength of cost is big, there is also the weak point that can not be ignored, such as labor intensity are big, process Complexity, thickness of thin, globality poor, easily ftracture, breathe freely ventilative under dynamic pressure effect, it is impossible to effectively prevent the diffusion of toxic gas Deng therefore, being badly in need of that a kind of air-tightness is good, the closed wall construction of the high improvement of safety coefficient.

The content of the invention

In view of the above-mentioned problems, the utility model provides a kind of resistance to compression waterproof fireproofing fire dam, simple in construction, obturation effect is good It is good and can effectively measuring body flexible encapsulated wall construction, there is preferable seal, can waterproof fireproofing, there is self-regeneration energy Power, local shock wave energy is absorbed, realize the purpose of resistance to compression waterproof fireproofing.

The utility model use design be：A kind of resistance to compression waterproof fireproofing fire dam, including：Slotting, bar-mat reinforcement with And three closed defence line.The slotting is to be formed on fire dam periphery with sledgehammer, hammer drill, pickaxe or mechanical execution, and slotting needs to see Hard bottom side firmly connects reality, cut depth with coal petrography：End cut 300mm, kerve 300m, inverted draw cut 100m；First of the fire dam is close It is after the heading sizes formwork of citadel, to be formed needed for self-healing concreting, thickness 200mm to close defence line, highly with Distance between inverted draw cut and kerve is equal, and apart from equal, lime stone can be produced by including in self-healing concrete for width and two end cuts Bacterium, activated by the corrosivity rainwater for acting on structure, repair that concrete is long-term use of and caused minute crack, Good leak tightness；The closed defence line of second of the fire dam is stacked by filling bag and formed, thickness 600mm, and filling bag shape is Cuboid, length are 1.2 times of tunnel inverted draw cut and kerve height, and width is 300mm with thickness tool, and there is material selection waterproof to subtract The polyurethane leather of shake effect, fill and grouting port and blow vent are provided with bag, adjacent filling bag is connected by the chain of rings, and the chain of rings is Circular stainless steel structure, filler are light foam concrete, and the porous of the filler makes it have low springform Amount so that its impact loading has a good absorption and dispersion, fill between bag and with it is first and third closed anti- Gap between line is filled by spraying negative poisson's ratio foam, can preferably absorb shock wave during pressing, while can play more Good sealing function；3rd closed defence line of the fire dam is equally formed by self-healing concreting, and thickness is also 200mm, height is equal with the distance between inverted draw cut and kerve, and width is with two end cuts apart from equal；The bar-mat reinforcement is located at the 3rd On the outside of the closed defence line in road, it is identical that size and surrounding slotting surround size, and reinforcing bar mesh is rhombus, and mesh size is 5 × 5mm, energy It is enough effectively to keep out rubble caused by impact load, reduce personnel's injury.

The beneficial effects of the utility model are：A kind of resistance to compression waterproof fireproofing fire dam, by slotting, bar-mat reinforcement and three close Close defence line composition.First of closed defence line forms with the 3rd closed defence line by self-healing concreting, self-healing coagulation penus In inorganic material, there is good fire protecting performance, while the self-healing feature of self-healing concrete, make fire dam that there is fine seal Energy；Negative poisson's ratio material between the filling bag material in the closed defence line of second, filler and filling bag has good close Close and absorb shock wave performance, resistance to compression can have been played well, block poison gas circulation and the effect of waterproof；3rd is closed Bar-mat reinforcement outside defence line can effectively keep out rubble caused by impact load, reduce personnel's injury.Whole fire dam is simple in construction, Easy for construction, thickness, resistance to compression, waterproof, fire prevention, sealing effectiveness etc. can meet that safety in production requires, have comprehensive well imitate Benefit.
