Abstract

The invention discloses a fast strengthening method for ultra-soft earth, comprising the following steps: (1) arranging the separation curtains to divide a plurality of construction areas in the area of waiting for strengthening; pouring water at the field; using the device of artificial inserting plate to insert and arrange the short plastic drainage plate; arranging the horizontal drainage pipeline and then paving a layer of sealing film on the pipeline; forming the strengthening device for shallow layer of ultra-soft earth through the vacuum pumping equipment connected with the pipeline; (2) vacuuming the strengthening device for shallow layer of ultra-soft earth; (3) integrally strengthening the foundation of the device. The fast strengthening method for ultra-soft earth has the advantages that the method can rapidly and effectively solve the problem of strengthening the ultra-soft foundation on the shallow layer, so as to supply the favorable conditions for the construction, suchas drainage sand cushion, plastic drainage board or bag sand-well, and supply an advanced art used for strengthening rapidly the foundation on silt or ultra-soft foundation on the filled silt with saving costs greatly.

Description

technical field

[0001] The invention relates to the technical field of foundation treatment of fixed buildings such as construction engineering, port engineering, and highway engineering, and in particular relates to an engineering technology for rapid reinforcement of ultra-soft soil foundations. Background technique

[0002] With the development of economic construction, the demand for ports in coastal cities has been significantly strengthened. In recent years, the construction of Tianjin Port, Lianyungang Port and Guangzhou Nansha Port has developed rapidly, and land reclamation projects have gradually increased. The dredger filling material used in land reclamation projects is mainly sand, but due to the large amount of sand consumed in construction projects, and for the protection of the environment and water conservancy safety requirements, local water conservancy, environmental protection and other departments restrict or prohibit sand mining, resulting in sand Due...
