Description

Technical Field

[0001] The utility model relates to the technical field of foundation pit support, in particular to a foundation pit support device for a soft foundation reinforcement water gate. Background Art

[0002] The water gate pit support device for soft foundation reinforcement is an innovative technology for reinforcing soft foundations. It aims to ensure the safety of water gate pit construction and improve the bearing capacity of the foundation. The device effectively resists soil pressure and water pressure by setting up support structures around the foundation pit, preventing foundation pit collapse and ensuring construction safety. The water gate pit support device for soft foundation reinforcement provides strong technical support for my country's water gate projects and helps my country's water conservancy infrastructure construction reach new heights.

[0003] According to the search of China Utility Model Publication No.: CN220335916U, a foundation pit support device for water gate engineering construction is disclosed. (1) During operation, by setting a foundation pit support composite layer consisting of a concrete spraying base, a support reinforcement grid, a concrete support surface, a number of support piles and a concrete bottom layer, the overall support strength and stability can be improved to avoid the occurrence of slope collapse. By setting a water gate base consisting of a water gate base, an inclined support seat and a horizontal lap seat, the foundation pit support composite layer can be reinforced on the basis of installing the water gate, thereby further improving the overall strength; (2) by setting short piles and grid limit pressure plates, the support reinforcement grid can be limited and supported. The support reinforcement grid can be used to improve the strength of the concrete spraying base and the concrete support surface layer. By setting a drainage pipe and a filter net, the water inside the foundation pit slope can be easily discharged while avoiding clogging of the drainage pipe.

[0004] However, there are some issues that need to be considered when implementing the above technical solutions: First, the sluice foundation pit is deep. When the excavation is deeper at one time, the slope protection is prone to collapse. The support device is an integral structure and cannot be supported as the excavation is carried out step by step, which poses a safety hazard. Secondly, the soft foundation will slowly deepen during construction. If the seepage water is not removed in time, it will affect the construction operation and reduce efficiency.
