Description

Technical Field

[0001] This utility model patent relates to the field of water conservancy engineering and bridge foundation construction technology, specifically to Larsen VI type steel sheet piles suitable for deep water areas. Background Technology

[0002] Currently, steel sheet pile cofferdams, commonly used in the foundation construction of hydraulic engineering projects in deep water areas, suffer from problems such as insufficient water-stopping performance and weak resistance to water flow impact. Traditional single-row steel sheet piles are prone to deformation and leakage in deep water environments, and the construction risk is particularly high under complex geological conditions.

[0003] Although double-row steel sheet pile structures are used in existing technologies, they mostly adopt conventional connection methods and have not been fully optimized to take into account the characteristics of deep water areas, resulting in low construction efficiency and high costs. Utility Model Content

[0004] The purpose of this invention is to provide Larsen VI type steel sheet piles suitable for deep water areas, aiming to solve the problems of improving construction efficiency, ensuring construction safety and improving project quality in the existing technology.

[0005] This utility model is implemented as follows: Larssen VI type steel sheet piles are applicable to deep water areas. The structure includes a first transverse steel sheet pile group, a second transverse steel sheet pile group, and a partition steel sheet pile group. The partition steel sheet pile group is connected between the first transverse steel sheet pile group and the second transverse steel sheet pile group by two half-width steel sheet piles and connecting components. The ends of the first or second transverse steel sheet piles are connected to the partition steel sheet pile group by corner piles. Two steel support structures are set between the first transverse steel sheet pile group and the second transverse steel sheet pile group. A walkway is connected to the uppermost steel support structure. The walkway is a 10mm patterned panel. Two sets of railings are set on the top of the walkway.

[0006] Specifically, in this embodiment, the first transverse sheet pile group and the second transverse sheet pile group are arranged in parallel to each other.

[0007] Specifically, in this embodiment, the connecting component includes a diaphragm buckle welded to the first transverse sheet pile group and the second transverse sheet pile group.

[0008] Specifically, in this embodiment, the partition buckle is composed of two symmetrical channel steels, each channel steel being 6m long.

[0009] Specifically, in this embodiment, the channel steel is closely attached to the outer wall of the conventional sheet pile and the half-width sheet pile to be welded, and single-sided welding is performed on all four sides, with a weld height of 12mm.

[0010] Specifically, in this embodiment, the steel support structure includes multiple corbel stiffening plates welded to the inner sides of the first and second transverse sheet pile groups. H-beam walers are welded to the top of the multiple corbel stiffening plates, and multiple H-beam supports are welded between the two H-beam walers.

[0011] Specifically, in this embodiment, the top of the corbel stiffening plate is provided with a protrusion, the size of which is adapted to the groove of the H-beam waler.

[0012] Specifically, in this embodiment, the dimensions of the H-beam waler are H300*300*10*15.

[0013] Specifically, in this embodiment, rubber sealing strips are provided inside the locking mechanism of the sheet piles in the first transverse sheet pile group, the second transverse sheet pile group, and the partition sheet pile group.

[0014] Compared with existing technologies, the Larssen VI type sheet piles provided by this utility model, suitable for deep water areas, adopt a double-row, six-type Larssen sheet pile structure. By combining the first transverse sheet pile group, the second transverse sheet pile group, and the partition sheet pile group, the first and second transverse sheet pile groups can be connected into a whole, enhancing the stability and rigidity of the overall structure. This significantly improves the water-stopping performance and resistance to water flow impact of the cofferdam. Furthermore, by using multiple partition sheet pile groups to divide the space between the first and second transverse sheet pile groups, the construction area can be defined, facilitating construction operations and management, while reducing water flow interference. The double-layer steel support structure can effectively control cofferdam deformation, improving the safety and stability of construction in deep water areas. Attached Figure Description
