Abstract

The invention relates to a macromolecular polymer filling / sealing grouting material for underground engineering and a construction technique thereof. The macromolecular polymer filling / sealing grouting material for underground engineering is prepared from two low-viscosity liquid substances, including resin and catalyst, wherein the resin comprises 75 parts of phenolic resin, 18-25 parts of foaming agent CFC141b, 5 parts of foam stabilizer SH-193 and 20 parts of urea-formaldehyde resin; and the catalyst comprises 50 parts of 65% methylbenzenesulfonic acid, 20 parts of polyethylene glycol, 35 parts of isopropyl ether and 5-7 parts of 85% phosphoric acid. Since the grouting material provided by the invention is prepared from the two low-viscosity liquid substances, including resin and catalyst, the product has the advantage of low consumption for filling, is convenient for underground transportation, can implement hollow filling and tunnel / face fall filling, can form a sealing wall or fire wall within a set range, can quickly block off underground harmful gas, and can implement permanent sealing, thereby enhancing the safety level, work efficiency and economic benefit of underground engineering, such as coal mines, tunnels and the like.

Description

technical field [0001] The invention relates to the technical field of underground engineering safety, in particular to a grouting material for underground engineering, which is mainly used in coal mine underground safety engineering, and is also used in subway tunnels, submarine tunnels, railway tunnels, water conservancy and hydropower projects, dams, etc. security area. Background technique [0002] In underground engineering disasters such as coal mines and tunnels, the problems of stratum conditions, water gushing, gas and underground fire fighting have always been hidden dangers and problems that people take seriously and need to be solved urgently. At present, coal mine safety accidents still account for a high proportion of all kinds of safety accidents. Coal mine disasters such as: roof fall, partial side, flood, fire, gas outburst, explosion and other treatment measures and preventive measures urgently need to be improved. Traditional coal and rock mass reinforcem...
