[0002] When constructing steel sheet piles on water, a pile driving barge is generally used and is equipped with a pile driving frame. However, sometimes limited by local resources and the high cost of ship dispatching, the water composite sheet piles generally adopt the construction process of combined use of a crawler crane, a vibratory hammer and a positioning frame. Therefore, there is a problem of the design selection of the positioning frame in the construction process. In the prior art, a single-layer frame structure is used to control the HZ-type sheet pile by restricting the four corner points thereof. In the process of pile sinking, when encountering a relatively hard soil layer, the sheet pile is prone to tilt and the verticality is difficult to control. Summary of the Invention

[0005] Each group of H-sheet pile fixing structures is provided with at least two layers, and each layer is located in the horizontal plane. Each layer includes an outer frame that is consistent with the outer contour of the cross-section of the H-sheet pile for the H-sheet pile to be inserted vertically. Steel plates are provided at both ends of the outer frame, and the steel plates and the ends of the outer frame form a leg space for the H-sheet pile. A vertical slit is formed through the middle of the steel plate, and spaced steel bars are provided on both sides of the slit to form a waist space and a pile sinking slideway for the H-sheet pile. The horizontal positioning of the H-sheet pile is realized through the leg space and the waist space, the vertical positioning of the H-sheet pile is realized through at least two layers of H-sheet pile fixing structures, and the common positioning of multiple H-sheet piles is realized through multiple groups of H-sheet pile fixing structures arranged at intervals.

[0006] Further, the lattice frame columns include four columns arranged in a rectangular plane, and the columns are fixedly formed by cross-welding through lattice members. Each layer in each group of H-sheet pile fixing structures is vertically corresponding.

[0007] Further, it further includes: support piles, which are vertically inserted into the water and at least two pairs are arranged at intervals in pairs. A horizontal support rod is fixed to each pair of support piles, and the lattice frame columns are horizontally placed between each pair of support piles and placed on the horizontal support rods.

[0010] Beneficial effects: Compared with the prior art, the advantages of the present utility model are as follows: The horizontal and vertical positioning of the H sheet pile is realized through the combination of section steels. The steel bar designed for waist positioning forms a waist slip while positioning, which can effectively improve the pile driving efficiency of the H sheet pile; The subsequent assembly and positioning of the Z sheet pile are also facilitated by the rapid and accurate installation of the H sheet pile.
