Windproof heat-preservation hood for microorganism solidification process in low-temperature environment and use method for windproof heat-preservation hood

Abstract

The invention provides a windproof heat-preservation hood for a microorganism solidification process in low-temperature environment and a use method for the windproof heat-preservation hood. The windproof heat-preservation hood is composed of a double-layer air inflation hood, a pressing-covering thin film and ground nails. In a cold and dry season, the requirements for temperature and humidity ofmicroorganism accumulation can be maintained utilizing a maintenance hood, a reinforcement reaction is made to proceed continuously, and certain strength and reinforcement effect are obtained. The windproof heat-preservation hood for the microorganism solidification process in low-temperature environment and the use method for the windproof heat-preservation hood can be used in a microorganism sand-fixation wind-protection engineering and can also be used in a desert management engineering.

Description

technical field [0001] The invention relates to a windproof and heat-preserving cover used in the microbial solidification process in a low-temperature environment and a method for using the same. The windproof and heat-preserving cover is used for afforestation in deserts or windproof and sand-fixing projects in desert areas. The inflatable double-layer inflatable cover is used to The soil that needs to be protected is separated from the outside world, and the air in the inflatable interlayer is used for heat preservation, and the microbial sand fixation project is carried out under cold and dry climate conditions to ensure the activity of microorganisms, prolong the applicable time of construction, and save time and cost. The invention belongs to the technical fields of microbial sand fixation and soil reinforcement.

AI Technical Summary

Problems solved by technology

[0002] Microbial grouting reinforcement technology is a technology that uses microorganisms to induce calcium carbonate crystallization. Through the low-pressure transmission of microbial cells and nutrients to the loose sandy soil foundation, calcium carbonate gel crystals are quickly precipitated in the sandy soil pores to improve the mechanical properties of the soil. Among them An important application is to use this technology in desert control, mainly to prevent wind and fix sand, and accelerate vegetation regeneration. However, the microbial reinforcement process needs to be carried out at a relatively high temperature. When the average temperature is lower than 10 degrees Celsius, the basic reinforcement reaction will stop. Therefore, in the northwestern and western regions of my country, the annual construction suitable temperature time is concentrated in the period from early summer to early autumn, usually from May to October, which greatly limits the time cost of windbreak and sand fixation.
