Abstract

A method for reinforcement of yielding soil of large area or hollow land includes the following procedures in order: 1. low position vacuum pre-press procedure as building cofferdam, filling in sludge to certain height, paving cloth and bamboo fence on the top, vertically inserting in water emission plastic boards, laying horizontal vacuum pipe net, installing vacuum pre-press system and sealing with mud layer of 0.8-1.5 m thick then vacuum bumping for pre-press; 2. high vacuum rate well point water reduction procedure as applying a high vacuum rate well point water reduction system on the mud sealing layer, removing well point pipe after the first round of water reduction; 3. low power strong tamping procedure as paving a layer of filling material on the mud sealing layer then tamping. Roller compact the surface after 2-3 rounds of procedure 2 and 3.

Description

Technical field:

[0001] The invention relates to a comprehensive reinforcement method for large-area soft ground. Suitable for silt, silt soil foundation. It is especially suitable for land reclamation or low-lying land filling projects where a large area of ​​soft soil is reinforced and its elevation is raised by dredging and filling mud. Background technique:

[0002] With the reform and opening up, construction land is becoming more and more scarce. For this reason, land reclamation is generally carried out in various coastal areas. These beaches not only have low bearing capacity, but also have a low ground elevation. According to the traditional method, sand blowing and earth-rock filling are required first. Consolidate the soft soil foundation and backfill materials on the beach. The traditional method is not only expensive, but also has a long construction period and seriously damages the ecological environment, which is not conducive to sustainable development. In...
