A structure on a muddy beach and its construction method

Abstract

The invention discloses a building on a mud flat and a building method thereof. The building comprises a prefabricated body. A plurality of watertight compartments and ballast compartments are arranged in the body through bulkhead in a divided mode. An explosive pipeline communicated with the exterior of the bottom of the body is arranged in the body. The building method comprises the steps that 1, the body is pulled to a preset installation position, water is injected into the ballast compartments to enable the bottom of the body to be located on a mud layer; 2, an explosive is placed from the explosive pipeline into the mud layer at the bottom of the body; 3, the explosive is detonated, drainage consolidation is made to be achieved on the mud layer at the bottom of the body, body sedimentation is carried out, and bottom supporting is rapidly achieved for the building body on a mud foundation. The building on the mud flat and the building method thereof have the advantages that uneven sedimentation of the mud layer can be avoided, the bottom of the building can resist slide, rapid solidification and sedimentation are achieved for the mud layer, and operation on the mud is convenient and rapid without mechanical equipment or personnel.

Description

technical field [0001] The invention relates to the technical field of construction, in particular to a rapid construction technology on muddy tidal flats. Background technique [0002] Silt soft foundations are widely distributed in river delta areas. With the development of economic construction, more and more large-scale engineering projects are built on such soft foundations, such as highways, airports, docks and water conservancy projects. The biggest problem encountered in this type of project is the treatment of muddy soft soil foundation. Soft foundation engineering problems are mainly deformation problems, that is, settlement problems. Because silt soil has the characteristics of low strength, low permeability coefficient, high water content, large void ratio, and high compressibility, its consolidation deformation is generally large, and some even exceed 40% of the thickness of its compressed layer, which is difficult for mechanical equipment and personnel.

AI Technical Summary

Problems solved by technology

[0003] At present, the methods for dealing with silt soft foundation in engineering mainly include surcharge preloading method and vacuum preloading drainage consolidation method, but these two methods have a long construction period and require mechanical equipment and personnel to operate on the silt, which increases the difficulty of construction, and There will be uneven settlement of silt soil, making construction more difficult
