Embodiment Construction

[0043] 1. Project overview

[0044] China Merchants Zhangzhou Development Zone is a reclamation area. There are many silt areas that are locally enriched due to cofferdam restrictions during reclamation. The silt is 10-20 meters thick and has a water content of 60-80%. It is in a flow-plastic state and belongs to low Strength, high compressibility, high sensitivity soil, extremely low physical and mechanical strength. Due to the needs of site construction, China Merchants Zhangzhou Development Zone Co., Ltd. plans to carry out soft foundation treatment on the 2# pit (silt enrichment area) in the first area, with an area of ​​about 64,000 square meters, which is divided into three areas: A, B, and C. In the outcropping area, the silt thickness is 15.2-18.4m; in B area is the filling area, the cover layer thickness is more than 3m, and the silt thickness is 12.0-14.2m. Area C is also filled with soil, and the proposed road is covered with a thickness greater than 6m and a silt ...

Abstract

The invention discloses a rapid drainage and consolidation treatment method for soft soil foundations, which comprises the following steps: (1) digging the silt to 2-3m below the delivery elevation, and backfilling the first layer of sand to 0.8-3m below the delivery elevation while digging 1.2m, insert the plastic drainage board to a depth of 8m below the handover elevation, cover the second sand cushion to 0.5-1.5m above the handover elevation, set up a drainage system to pump water continuously; (2) start the first dynamic load after 12-18 days after the backfill is in place , the energy is 500-650 kJ, and the depth of the ramming pit does not exceed 1.5m; (3) The second dynamic load after 5-8 days, the energy is 700-900 kJ, and the depth of the ramming pit does not exceed 1.5m, (4) 5-8 Start the third dynamic load after 5-8 days, the energy is 1100-1500 kJ, and the depth of the ramming pit does not exceed 1.5m; m; (6) After 5-8 days, excavate excess filler, perform 600 kilojoule full-field dynamic load once, and level and hand over the work twice. The invention can reduce the cost by 75%, and shorten the construction period from more than 360 days to about 90 days.

Description

technical field [0001] The invention relates to a soft soil foundation treatment method, in particular to a soft soil foundation rapid drainage consolidation treatment method. Background technique [0002] With the development and construction, the treatment of soft soil foundation, especially the tidal flat foundation treatment in coastal areas is also very important. Soft soil refers to fine-grained soil in a soft plastic state with high natural water content, large void ratio, high compressibility, low shear strength and bearing capacity, and large thixotropy deposited on coasts, lakes, valleys, and river beaches, such as silt , muddy soil, peat, peaty soil, and other highly compressible saturated clay, silt, etc. For saturated silty clay or silt, due to its high water content, high clay content, low coarse particle content, and poor permeability, at present, drainage preloading, vacuum preloading, dewatering preloading, electroosmosis, etc. are usually used. Consolidat...
