[0037] Embodiment 1

[0038] Figure 1 This is a structural schematic diagram of an assembled steel sheet pile support structure according to an embodiment of the present invention. Figure 1 This assembled steel sheet pile support structure includes a standard section steel sheet pile 2 and a steel sheet pile universal connector 1 for connecting two adjacent standard section steel sheet piles; both left and right ends of the steel sheet pile universal connector 1 are provided with a clamping groove that can be clamped and matched with the end of the standard section steel sheet pile 2, and a detachable positioning block is provided at the position corresponding to the clamping groove on the steel sheet pile universal connector 1, and at least two positioning blocks are arranged at intervals along the length direction of the clamping groove, and one end of the standard section steel sheet pile 2 extending into the clamping groove is provided with a positioning groove that can be plugged and matched with the positioning block.

[0039] Exemplarily, two, four or more positioning blocks can be arranged at intervals along the length direction of the snap-in groove. Technical personnel in this field can select the number of positioning blocks to be arranged according to actual needs. By installing multiple positioning blocks, multi-point positioning of the steel sheet pile universal connector 1 and the standard section steel sheet pile 2 can be achieved, which is beneficial to improve the structural stability of the connection between the standard section steel sheet pile 2 and the steel sheet pile universal connector 1, prevent the standard section steel sheet pile 2 from loosening, and ensure the structural strength and safety of this support structure after construction.

[0040] In actual application, the support structure can be formed by plugging and matching the three components of the standard section steel sheet pile 2, the steel sheet pile universal connector 1, and the positioning block, which is conducive to reducing the construction difficulty and improving the construction efficiency. By installing the positioning block on the steel sheet pile universal connector, the positioning block can not only realize the positioning of the standard section steel sheet pile 2 on the steel sheet pile universal connector 1, but also improve the connection strength between the steel sheet pile universal connector 1 and the standard section steel sheet pile 2, which is conducive to improving the overall structural strength and stability of the support structure.

[0041] Figure 2 This is a schematic diagram of the structure of a positioning block in an assembled steel sheet pile support structure according to the first embodiment of the present invention. Figure 2 Preferably, an assembly groove for installing a positioning block 9 is provided on the universal connector of the steel sheet pile, the assembly groove is connected to the clamping groove, and a conical end portion 10 is provided at one end of the positioning block 9 facing the assembly groove, and both the assembly groove and the positioning groove are conical grooves.

[0042] In actual use, by adopting the tapered groove to cooperate with the tapered end 10 of the positioning block 9, it is not only convenient for the installation of the positioning block 9, but also conducive to improving the stability of the positioning block 9 after installation, ensuring that the positioning block 9 can continuously and stably support the standard section steel sheet piles, so that each standard section steel sheet pile is tightly connected with the steel sheet pile universal connector at its left and right ends, ensuring the sealing of this support structure after construction.

[0043] Figure 3 This is a schematic diagram of the structure of a standard section steel sheet pile in an assembled steel sheet pile support structure according to the first embodiment of the present invention. Figure 3 Preferably, the standard section steel sheet pile 2 is a wave-shaped structural member, and at least two positioning grooves 3 are arranged vertically at intervals along the standard section steel sheet pile 2. Compared with the standard section steel sheet piles 2 of other structures, the standard section steel sheet piles 2 of the wave-shaped structure not only have higher structural strength, but also facilitate the construction personnel to bend the standard section steel sheet piles 2 as needed, and are easy to operate, which improves the applicability of the standard section steel sheet piles 2 to different constructions, helps to reduce the construction difficulty, and improves the construction efficiency.

[0044] Preferably, both left and right ends of the standard section steel sheet pile 2 are provided with a tenon head 4 that cooperates with the clamping groove. In actual use, the tenon head 4 and the clamping groove are clamped together to form a stable mortise and tenon structure, which is conducive to further improving the stability of the connection between the standard section steel sheet pile 2 and the steel sheet pile universal connector. By using the tenon head 4 to cooperate with the clamping groove, not only can the two components be stably connected, but also the assembly construction is convenient.

[0045] The assembled steel sheet pile support structure described in this embodiment has the advantages of good applicability, simple structure, and easy construction. The support structure can be formed by plugging and matching the three components of standard section steel sheet piles, steel sheet pile universal connectors, and positioning blocks, which is conducive to reducing the difficulty of construction and improving construction efficiency. At the same time, by installing positioning blocks on the steel sheet pile universal connector, the positioning blocks can not only realize the positioning of the standard section steel sheet piles on the steel sheet pile universal connector, but also improve the connection strength between the steel sheet pile universal connector and the standard section steel sheet pile, which is conducive to improving the overall structural strength and stability of the support structure.

[0047] Figure 4 This is a schematic diagram of the structure of a universal steel plate connector in an assembled steel sheet pile support structure according to the second embodiment of the present invention. Figure 4 This embodiment is improved on the basis of the above embodiment, and the specific improvement is as follows: a bendable deformation portion 7 is provided in the middle of the steel sheet pile universal connector 1.

[0048] Exemplarily, the left and right ends of the steel sheet pile universal connector 1 are provided with snap-in grooves 5, and assembly grooves 6 are provided at positions corresponding to the snap-in grooves 5. The middle deformation portion 7 is a hollow corrugated structure, and a cavity 8 for facilitating deformation is provided in the deformation portion 7. Corrugated structures are provided on the front and rear sides of the deformation portion 7. By arranging the deformation portion 7 in the middle of the steel sheet pile universal connector 1, construction personnel can also bend the steel sheet pile universal connector 1 according to construction needs. For example, the steel sheet pile universal connector 1 can be bent to 90 to 180 degrees according to different construction and installation ranges to facilitate the subsequent installation and construction of standard section steel sheet piles, thereby further improving the applicability of this support structure in actual construction.

[0049] In actual application, in order to improve the structural strength and stability of the steel sheet pile universal connector 1 after bending, the construction personnel can also insert a positioning column in the cavity 8 of the steel sheet pile universal connector 1, and use a pile driver to drive the positioning column into the soil layer, so as to use the positioning column to further limit the steel sheet pile universal connector 1 and improve the stability of the steel sheet pile universal connector 1.

[0059] S3. Adjust the length of the standard section steel sheet pile according to the preliminary positioning of the steel sheet pile universal connector, and insert the adjusted end of the standard section steel sheet pile into the clamping groove of the steel sheet pile universal connector to achieve the connection between the steel sheet pile universal connector and the standard section steel sheet pile, and obtain the enclosed area of ​​the support structure.

Construction personnel can conduct visual inspection of the support structure after the construction is completed, and use sandbags or steel sheet piles to repair the leaks according to the inspection results. Technical personnel in this field can also choose other inspection methods and repair methods to repair the support structure according to actual needs to ensure the stability of the support structure.
