Problems solved by technology

Because the production of brick and tile factories requires a large amount of clay, a large number of deep pits will be dug, and a large amount of mud will be filled into the pits to form mud pools. The idle mud pools will not only have a negative impact on groundwater and surface water, but will also seriously endanger the surrounding ecology. ...

Embodiment 1

[0027] A method of backfilling large-area mud sites, taking a mud pool in Shaoxing as an example, the mud storage pool is the soil borrow pool of the original brick factory, and there is a lot of waste mud generated during construction, as shown in the attached figure 1 As shown, the treatment area is 125,688 square meters, the volume of pool water is 201,547.1 cubic meters, and the thickness of the stored mud is about 2 to 15m. It is about 300m long and 400m wide; the surface layer of the mud pool is mud sewage 1, and the lower part is mud 2 with extremely low bearing capacity. If people and machinery fall into it, life and property will suffer heavy losses, and the pollution in the mud pool is serious, and animals and plants cannot live naturally. To survive, in order to ensure safety and restore the ecological environment, it is necessary to carry out ecological treatment on the mud pool.

Abstract

The invention relates to a soil backfilling method for a large-area mud site. The soil backfilling method for the large-area mud site is mainly used for soil backfilling of the surface layer of a mudpond which is treated ecologically. The soil backfilling method for the large-area mud site comprises the following implementation steps: (1) preparing before construction; (2) laying a first layer ofgeotechnical cloth; (3) laying a pressure-bearing bamboo net; (4) laying anti-sliding non-woven geotechnical cloth; (5) driving machinery to enter the site, and carrying out block landfilling according to the design, wherein the landfilling sequence is symmetric landfilling; and (6) carrying out leak filling, flattening the surface layer and slightly compacting the surface layer. By the method, it can be ensured that by soil backfilling of the surface layer, the mud pond which is treated ecologically can be isolated from mud, and after the mud pond is filled with water, agricultural and fishery activities such as breeding and lotus root planting can be carried out.

Description

technical field [0001] The invention belongs to the technical field of ecological construction, and in particular relates to the ecological treatment of a mud field, in particular to a method for backfilling a large-area mud field. Background technique [0002] With the acceleration of China's urbanization process, there are a large number of construction projects in urban areas every year, and the waste mud generated by construction is also increasing significantly. Because the production of brick and tile factories requires a large amount of clay, a large number of deep pits will be dug, and a large amount of mud will be filled into the pits to form mud pools. The idle mud pools will not only have a negative impact on groundwater and surface water, but will also seriously endanger the surrounding ecology. environment, and the country puts heavy pressure on environmental protection issues, so how to safely dispose of the landfilled mud pools and protect the ecological envir...
