Emergency covering material, and construction method and application thereof

Abstract

The invention discloses an emergency covering material, and a construction method and an application thereof. The problems that an emergency site with complex site conditions is extremely difficult toconstruct, and cannot be quickly covered are solved. The emergency covering material comprises a curing agent, an adsorbent, a gelatinizing agent, a deodorizing disinfectant, a dye and a solvent. Theinvention further provides a construction method and an application of the covering material. The covering material can be used for carrying out emergency rapid covering on an emergency pollution event site, so that rapid rain and sewage diversion, toxic and harmful substance isolation and safety warning effects on the emergency event site are realized, and secondary and chain environmental hazards of the emergency event are greatly reduced. A covering layer has good rain-proof and seepage-proof effects and good peculiar smell and pollutant isolation effects, and is environmentally friendly.In addition, the covering material can also play a role in fire prevention and dust prevention when applied to fields of fire disasters, earthquakes and the like, and also has the advantages of wide application, high economic feasibility and high practicability.

Description

technical field [0001] The invention relates to the technical field of emergency disposal of emergencies, in particular to an emergency covering material, construction method and application applied to pollution sources of emergencies. Background technique [0002] At present, emergencies occur frequently, and their emergency response has become an important problem to be solved by the current society. Common emergencies include factory safety production accidents (explosions, fires, leakage of dangerous chemicals, etc.) and accompanying environmental emergencies, urban or forest fires, earthquakes, etc., resulting in building collapses and epidemics. The secondary environmental hazards of these events include dust, volatilization of toxic and harmful gases, and soil and groundwater pollution caused by the infiltration of dangerous goods, which seriously threaten the ecological environment and human health. Although the use of dust-proof or waterproof materials can alleviat...

AI Technical Summary

Problems solved by technology

Although the use of dust-proof or waterproof materials can alleviate the above hazards to a certain extent, although geotextile materials are both economical and dust-proof, they cannot prevent the infiltration of sewage and rainwater, and cannot control the volatilization of odors or even toxic and harmful gases. Moreover, the construction process is complicated, and it is not suitable for long-distance operations; although anti-seepage materials such as HDPE membranes can meet the functions of waterproof, anti-seepage and anti-odor, they need to be laid manually like geotextiles, and it is extremely difficult to construct on-site construction in complex emergencies Large and cannot be covered quickly

In addition, the ground temperature of accident sites such as explosions and fires is relatively high, and the above materials cannot meet the relevant requirements for fire protection and flame retardancy.
