A kind of quick crust structure of soft foundation and its manufacturing method

Abstract

The invention discloses a quick crusting structure for soft foundation reclamation and a production construction method thereof. The structure at least comprises a penetration base layer, a negative pressure drainage layer, a soft base dredging layer and a penetration pit, wherein the soft base dredging layer is characterized in that silt is dredged and backfilled to a reclamation base, the drying and curing time of the soft base dredging layer is accelerated by the penetration base layer and the negative pressure drainage layer, and finally the crusting reclamation is completed. According to the reclamation construction method provided by the invention, a curing agent is added into dredging silt to increase the particle size of mud, and the drainage of the soft base dredging layer is accelerated to shorten the crusting time; after the reclamation is completed, the penetration base layer can be further used as a underground reservoir for storing water, so that natural resources can be utilized more effectively.

Description

technical field [0001] The invention is a construction method for soft ground, which uses the concept of rapid crusting to form a solidified land structure, and especially refers to a construction method for soft soil such as various silt areas and swamps. Background technique [0002] In an era where every inch of land is extremely expensive, how to effectively utilize land resources is a problem that human beings must face. Generally, the traditional land reclamation method for coastal low-lying areas needs to excavate a large amount of sea sand, backfill it to the land reclamation block, and use The negative pressure method removes water and dries the wetland. This construction method not only needs to use a large amount of sediment, but also causes a lot of excavation, transportation, mixing and other transportation and equipment costs, and causes the consumption of earth and rock resources in other areas. It is not suitable for resource application. It is in line with e...

AI Technical Summary

Problems solved by technology

[0004] Although the land reclamation method disclosed in the previous case can save resources more than the previous method of backfilling with sand and gravel, mixing a certain proportion of tailings sand and cement in the silt can only be applied to a specific range and has a relatively large use At the same time, the problems of ground drainage and water resource recovery cannot be solved after land reclamation is completed. Therefore, the present invention proposes an innovative manufacturing method and land reclamation structure for quick crusting of soft foundation land, and effectively solves the above problems at the same time. As a A land-making method that efficiently utilizes resources
