The pressure on the retaining structure inside and outside the wall caused by excavation of the foundation pit, as well as the settlement and excavation of the foundation steel sheet pile pit structure caused by horizontal displacement, lateral deformation of the retaining structure, soil type, and unloading, will cause the soil at the bottom of the pit to rise. The movement of the surrounding rock in the foundation pit is mainly caused by deformation and frost heave of the support structure. The most direct reason for trench excavation construction is the geological movement that affects the horizontal displacement of the wall. When shallow trench excavation has not yet set up rigid support, the horizontal displacement direction of the body or flexible wall is triangular, and cracks on the steel sheet piles at the top of the trench do not occur outside the pit. As the depth increases, the excavation of the trench and the rigid wall continue to move laterally towards the triangular or parallel steel sheet piles inside the trench, including the price of cold-formed steel sheet piles, the displacement of the flexible wall gradually moves towards the outer upper part of the trench wall, and the protruding groove on the abdomen. The main reason for this phenomenon is mainly due to the steel piles. Non elastic horizontal displacement in passive zone soil cracks.
With the continuous progress of the project, the construction technology of steel sheet piles has been summarized and on-site management has been strengthened. Scientific methods have been adopted to optimize the construction plan proposed by the construction party, ensuring construction costs and quality control. The construction personnel have worked tirelessly on the heating network and thermal protection station project in Wuxi, and the quality and quantity must be completed.
The construction of Larson steel sheet piles is very important in Larson's steel sheet piles. The construction of Larson's steel sheet pile cofferdam is strict, and we must ensure that Larson's steel sheet piles and steel sheet piles correctly play Larson's vertical axis. It is necessary to control the accuracy of Larson steel sheet piles, prevent deformation and buckling of steel sheet piles, and improve the penetration ability of Larson steel sheet piles. It must be installed on the Larson steel sheet pile guide frame and steel sheet piles, The following is an introduction to how to install Larson steel sheet piles for Wuhan guide frame construction.
