Problems solved by technology

The rodent control method with instruments does not pollute the environment and is simple and easy to implement, but the effect of the mousetrap decreases rapidly when the mousetrap is used continuously, and the work efficiency is low; the drug rodent control has high efficiency and wide application, but may accidentally injure natural enemies or pollute the environment; biological methods advocate the use of natural enemies to control pests Rats, but limited by the insufficient number of natural enemies; ecological rodent control to control, transform and destroy the living environment and conditions that are conducive to the survival of rodents, making it difficult for rodents to survive and reproduce

Abstract

The invention relates to an arid desert region soil engineering slope bandicoot-caused damage prevention and control method. Reinforced concrete grid beams are embedded into a slope foundation layer, and sand gravels are filled in the reinforced concrete grid beams to destroy bandicoot nidification environments so as to achieve slope surface bandicoot-caused damage prevention and control effect. The method is simple, convenient, ecological and long-acting. According to ecological habits, living environments and other characteristics of levee slope bandicoots, a slope surface layer changed foundation structure is adopted, and a loose earth's surface structure which does not facilitate bandicoot nidification is created so as to achieve the purpose of effectively controlling damage caused by the levee slope bandicoots. A concrete grid beam structure is constructed on the ground slope to reinforce a slope soil body and ensure the slope stability. Sand gravel fillers are filled into concrete beam grids so as to inhibit bandicoot nidification and reduce the erosion scouring effect of rainwater. By means of the method, the problem that the bandicoot-caused damage prevention and control effect in the desert environment is low is solved, the ecological environmental protection requirements of a large canal system for slope bandicoot-caused damage prevention and control are met, and technical support is provided for bandicoot-caused damage prevention and control of arid desert region soil engineering facilities.

Description

technical field [0001] The invention discloses a method for preventing and controlling rodent damage on soil slopes, in particular to the control of rodent damage on slopes formed during the construction of roads and water conservancy projects in desert areas, especially the ecological prevention and control technology for rodent damage on clay slopes. Background technique [0002] In the arid region of Northwest China, the desert area is vast, and the oasis resides in the form of patches. Due to economic and social development, some large-scale engineering projects, such as railways, highways and water diversion projects, inevitably have to pass through the desert area with harsh environmental conditions. The improvement of the ecological environment along the project line has attracted some desert animals to gather and migrate here, especially rodent animals mainly such as large gerbils. Compared with the huge desert environment, it is difficult for some equipment and drug...
