Abstract
The utility model discloses a kind of antiseepage fire prevention mine shaft, comprise outer layer of concrete, impervious barrier, back-up coat, inner concrete layer and fireprotection layer, inside described outer layer of concrete, impervious barrier is set, inside impervious barrier, back-up coat is set, arrange inner concrete layer inside back-up coat, the inwall of inner concrete layer arranges fireprotection layer, described impervious barrier is polyethylene polypropylene fiber waterproof coiled material layer, described back-up coat is oven wire mesh blanket, and described fireprotection layer is foaming modification phenolic aldehyde layer.Antiseepage fire prevention mine shaft of the present utility model, effectively can prevent infiltration phenomenon and the breaking out of fire phenomenon of country rock, compressive strength is high, and safety is good.
Description
Technical field
The utility model relates to coal mine construction technical field, particularly relates to a kind of antiseepage fire prevention mine shaft.
Background technology
When digging vertical in colliery, be generally that down explosion is excavated from ground, carry out borehole wall supporting with concrete.Because pit shaft geological conditions is comparatively complicated, if crack appears in concrete shield, the borehole wall just there will be infiltration phenomenon, affects the use of pit shaft.In addition, in the process of fluting vertical, Mine Dust, gas explosion accident occur sometimes, can cause huge personnel and property loss, when gas explosion time in mine, the flame surface temperature of high-temperature gas raises, increased flame speeds, combustible is easily lighted breaking out of fire.Current mine shaft is scarcely prevented fires, non-watertight, and compressive strength is low.
Utility model content
The purpose of this utility model there is provided a kind of antiseepage fire prevention mine shaft, and effectively can prevent infiltration phenomenon and the breaking out of fire phenomenon of country rock, compressive strength is high, and safety is good.
The technical solution adopted in the utility model is as follows:
A kind of antiseepage fire prevention mine shaft, comprise outer layer of concrete, impervious barrier, back-up coat, inner concrete layer and fireprotection layer, inside described outer layer of concrete, impervious barrier is set, inside impervious barrier, back-up coat is set, arrange inner concrete layer inside back-up coat, the inwall of inner concrete layer arranges fireprotection layer, described impervious barrier is polyethylene polypropylene fiber waterproof coiled material layer, described back-up coat is oven wire mesh blanket, and described fireprotection layer is foaming modification phenolic aldehyde layer.
The thickness of described impervious barrier is 2-5mm.
The thickness of described back-up coat is 0.2-0.3mm.
The thickness of described fireprotection layer is 0.1-0.3mm.
Compared with the prior art, the beneficial effects of the utility model are as follows:
Antiseepage fire prevention mine shaft of the present utility model, by arranging outer layer of concrete, impervious barrier, back-up coat, inner concrete layer and fireprotection layer, inside described outer layer of concrete, impervious barrier is set, inside impervious barrier, back-up coat is set, inner concrete layer is set inside back-up coat, the inwall of inner concrete layer arranges fireprotection layer, effectively can prevent the infiltration phenomenon of country rock and avoid fire phenomena, greatly strengthen the overall construction intensity of mine shaft, make it meet the safety requirements of coal mine.Described impervious barrier is polyethylene polypropylene fiber waterproof coiled material layer, polyethylene polypropylene fiber waterproof coiled material be by after the melting such as polyethylene, auxiliary agent in a kind of flexible waterproof sheet that nonwoven polypropylene fabric is composited, its rough surface, can bond together securely with outer layer of concrete, form the water-proof system of a rigid flexible system, the geological conditions of pit shaft complexity can well be adapted to, avoid pit shaft to seep water; Described back-up coat is oven wire mesh blanket, and compressive strength is high; Described fireprotection layer is foaming modification phenolic aldehyde layer, foaming modification phenolic aldehyde layer is when running into naked light, and its surface carbonization can occur, carburization zone by the material of inside and oxygen completely isolated, there is heat insulation and fireproof function, can effectively isolate thermal source and dust when breaking out of fire.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Detailed description of the invention
See accompanying drawing, a kind of antiseepage fire prevention mine shaft, comprise outer layer of concrete 1, impervious barrier 2, back-up coat 3, inner concrete layer 4 and fireprotection layer 5, inside described outer layer of concrete 1, impervious barrier 2 is set, back-up coat 3 is set inside impervious barrier 2, inner concrete layer 4 is set inside back-up coat 3, the inwall of inner concrete layer 4 is arranged fireprotection layer 5, described impervious barrier 2 is polyethylene polypropylene fiber waterproof coiled material layer, described back-up coat 3 is oven wire mesh blanket, described fireprotection layer 5 is foaming modification phenolic aldehyde layer, the thickness of described impervious barrier 2 is 3mm, the thickness of described back-up coat 2 is 0.3mm, the thickness of described fireprotection layer 5 is 0.2mm.Antiseepage fire prevention mine shaft of the present utility model, effectively can prevent the infiltration phenomenon of country rock and avoid fire phenomena, greatly strengthen the overall construction intensity of mine shaft, it is made to meet the safety requirements of coal mine, impervious barrier 2 is polyethylene polypropylene fiber waterproof coiled material layer, polyethylene polypropylene fiber waterproof coiled material is by polyethylene, in a kind of flexible waterproof sheet that nonwoven polypropylene fabric is composited after the meltings such as auxiliary agent, its rough surface, can bond together securely with outer layer of concrete 1, form the water-proof system of a rigid flexible system, the geological conditions of pit shaft complexity can well be adapted to, pit shaft is avoided to seep water, back-up coat 3 is oven wire mesh blanket, and compressive strength is high, fireprotection layer 5 is foaming modification phenolic aldehyde layer, foaming modification phenolic aldehyde layer is when running into naked light, and its surface carbonization can occur, carburization zone by the material of inside and oxygen completely isolated, there is heat insulation and fireproof function, can effectively isolate thermal source and dust when breaking out of fire.
