Method for treating quicksand stratum drainage ditch slope collapse and purifying and recycling ditch water

Abstract

The invention belongs to the technical field of drainage ditch slope treatment, and discloses a method for treating quicksand stratum drainage ditch slope collapse and purifying and recycling ditch water. Geotextile is sewn into geotechnical bags, the geotechnical bags are filled with corresponding fillers to form geotechnical filling bags, and the drainage ditch slope is built and protected. The method specifically comprises the following steps that filling preparation of the geotechnical filling bags is conducted, specifically, white artificial leather base cloth is selected as the geotextile to be sewn into the geotechnical bags, and the geotechnical bags are filled with the corresponding fillers to form the geotechnical filling bags which are used for building and protecting the drainage ditch slope; and a foundation is paved. According to the method, a new geosynthetic material, a new plastic steel composite sheet pile material, miniature concrete piles, timber piles and farmland drainage ditch slope treatment are successfully combined, the problems of collapse, slippage and the like of the ditch in an irrigation area are effectively solved, field infiltration water drained into the ditch can be filtered and purified, and ditch water recycling is achieved.

Description

technical field [0001] The invention belongs to the technical field of drainage ditch slope treatment, and in particular relates to a method for controlling drainage ditch slope collapse in quicksand strata and purifying and reusing ditch water. Background technique [0002] Geotechnical bag refers to filling soil, stone and other materials into geosynthetics to form a bag that meets the engineering filling requirements. The sewn geotextile woven bag is filled with soil, sand, gravel, construction waste or other materials. The material is formed into a bag, and then paved according to a certain arrangement to reinforce the foundation geotechnical bagging technology and its derivative technology. [0003] Land salinization is a serious problem facing the world's agricultural development, and it is also one of the important reasons for land degradation and soil desertification. In arid and semi-arid areas, in order to ensure the development of irrigated agriculture, it is nec...
