Anti-flaming bag-packing small coal fast building material capable of flexibly bearing pressure

Abstract

The invention discloses quick a laying material capable of realizing the flexible load bearing and the fire retardation of bagged crushed coal, belonging to the building material. The quick laying material is made of various crushed coals, 20kg debris (less than 3cm, the finer the better), 10kg to 15kg water and 2kg to 4kg composite additive which are evenly stirred and then are packed in a woven bag. The invention has the advantages that: the material adopts composite viscose to fill in the gap between the coal and the debris inside the bag, thereby having good airtightness and preventing the slide between bags during building various wall bodies; when the quick laying material is under the pressure of a top plate and a bottom plate, the material can increase compressive resistance by means of contraction deformation, thereby obtaining the engineering effects that the material realizes deformation without air leakage and is tighter under increasing pressure; and the material which is time-saving, trouble-saving, labor-saving and material-saving, is convenient for construction. The quick laying material can quickly seal a goaf, an old underground chamber and a laneway; moreover, the material which has excellent sealing effect and can resist the pressure of the top plate, is of great significance to the disaster prevention in a gassy mine.

Description

technical field [0001] The invention relates to a building material, in particular to a flexible pressure-bearing, flame-retardant bagged crushed coal quick-build material. Background technique [0002] Due to the needs of production and safety in underground coal mines, a lot of work such as wall building, sealing, heat insulation filling, and upper and lower corners of roadways must be carried out. The characteristics are: fast, flexible pressure bearing, no cracking or collapse after pressure, and maintaining the integrity of the ventilation system. In the past, such materials were mainly transported from the ground to the underground, such as bricks, stones, cement, sand and gravel. Not only the transportation volume is large and there are many links, but some places in the underground are unable to enter the vehicle because there are no tracks, and pedestrians are difficult, which makes this transportation more difficult. Time-consuming, labor-intensive, and labor-inte...

Problems solved by technology

[0004] In order to overcome the need for long-distance transportation of raw materials such as bricks, stones, cement, sand, loess, etc. from the ground to the underground in order to overcome the existing technology of underground building, wall building, and sealing, it is time-consuming, laborious, labor-intensive, and sometimes cannot be transported due to poor underground conditions. Disadvantages and shortcomings of brick and stone masonry, the present invention provides a flexible pressure-bearing, flame-retardant bagged crushed coal quick-laying material, which is made of crushed coal or crushed coal gangue in underground coal mines.
