Marine foundation treatment method

How to do the sea foundation treatment method? The ground treatment on land in order to lay the foundation in the soft soil, for the thick soft soil is usually used pile machine structure, lay a few piles as reinforcement in the soil layer; For shallow soil, the replacement method is used to excavate the soft soil and fill with solid material. In order to effectively solve the construction and maintenance problems of soft subsoil, it is necessary to use deep cement mixing vessel (DCM vessel).

Foundation pit supporting construction unit

Foundation pit supporting construction unit, foundation pit supporting plays the role of retaining soil, stabilizing the bottom of the pit and intercepting water in the engineering construction, ensuring the safety of the surrounding environment and the safety of the engineering construction. In order to ensure the construction safety of structural engineering and the safety of the surrounding environment, it is necessary to rely on the foundation pit support to control the soil surface. Its main function is to fix and ensure the stability of the bottom of the pit by blocking water flow, soil resistance and other ways. The retaining structure of foundation pit plays the role of temporary retaining structure during construction.
