Shallow soft soil foundation solidifying structure and construction method thereof

Abstract

The invention discloses a shallow soft soil foundation solidifying structure which includes a shallow solidifying body arranged under a beach shallow raw mud surface, a deep replacement body is arranged at the bottom of the shallow solidifying body, and the edge of the shallow solidifying body is provided with an anti-sliding wall for preventing the shallow solidifying body from sliding. The invention also provides a construction method of the shallow solidifying body, the anti-sliding wall and the deep replacement body in the shallow soft soil foundation solidifying structure. The shallow soft soil foundation solidifying structure and the construction method have the beneficial effects that the process can take materials on site, can make full use of weak mud or mucky soil on site, is lowin cost, environment-friendly and ecological and can be widely used in dams, roads, docks, storage yards, underground continuous walls, cement mixing piles and other fields.

Description

technical field [0001] The invention relates to the fields of water conservancy and water transportation and coastal marine engineering, in particular to a shallow soft soil foundation solidification structure and a construction method thereof. Background technique [0002] Soft soil has the characteristics of high water content, high compressibility, low mechanical strength, etc., especially the silt or muddy soil in a flow-plastic state, which is the soil layer that needs to be treated emphatically in the project. For this kind of soft soil foundation, the commonly used treatment methods include drainage consolidation method, replacement method, pile foundation method and so on. [0003] The drainage consolidation method shortens the drainage path of the foundation soil by setting drainage channels in the soil body, and accelerates the drainage consolidation speed of the soil body by using self-weight or preload to increase the strength of the foundation soil. This method...
