Abstract

The invention relates to a soft foundation fast separating and punning method, which comprises the following technical steps: step 1, water and gas separating integral tube well layout; step 2, water and soil separating and water descending; step 3, water and gas separating construction after dynamic reinforcement; step 4, tube well backfilling. The soft foundation fast separating and punning method has the advantages that water and gas separating tube well water descending is combined with a dynamic reinforcement method, the requirement on water descending depth is met, pore water pressure generated after dynamic reinforcement can also be rapidly dispersed, and the soft foundation fast separating and punning method is applicable to the requirement of dynamic reinforcement of low-permeability soil.

Description

technical field

[0001] The invention relates to a soft ground treatment method, in particular to a soft ground rapid separation and compaction method suitable for large-area weak ground reinforcement treatment. The utility model is applicable to the site of sand and mud dredging that cannot meet the required bearing capacity and compaction degree of the design, and belongs to the technical field of foundation treatment. Background technique

[0002] At present, land reclamation along the river and coastal tidal flats is used to solve the land shortage. Due to the high water content, high rheology, high compressibility and low strength of the new dredged fill. After the filling is completed, it is difficult to enter the mechanical equipment to start the follow-up construction. In order to speed up the construction, the methods of well point dewatering combined with dynamic ramming, tube well dewatering combined with point ramming and vacuum preloading are commonly used. It ma...
