[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] refer to Figure 1 As shown, the utility model provides a support and positioning device for a combination of steel sheet piles and steel pipe piles, comprising: a plurality of steel pipe pile bodies 1 and steel sheet pile bodies 3 distributed at equal intervals, a lock buckle 2 for waterproofing is provided between the steel pipe pile body 1 and the steel sheet pile body 3, a positioning assembly is installed between two adjacent steel pipe pile bodies 1, the positioning assembly comprises two clamping seats 8 and an adjusting member installed between the two clamping seats 8, the adjusting member is used to adjust the axial length between the two clamping seats 8, and the two clamping seats 8 are respectively clamped on the steel pipe pile bodies 1 on both sides.

[0024] Combination Figure 1-2 As shown, the adjusting member includes a screw rod 6 and screw tubes 7 screwed to both ends of the screw rod 6 , and ends of the two screw tubes 7 facing away from the screw rod 6 are respectively installed on opposite sides of two clamping seats 8 .

[0025] As mentioned above, when using the steel pipe pile body 1, steel sheet pile body 3, lock 2 and positioning assembly provided by the utility model, after multiple steel pipe pile bodies 1 are inserted into the soil, the two clamping seats 8 on the positioning assembly are respectively clamped on two adjacent steel pipe pile bodies 1. At this time, the distance between the two clamping seats 8 is adjusted by the adjusting member, so as to adjust the distance between the two locks 2. When the position adjustment of the tops of the two locks 2 is stable, it is convenient to allow the bottom ends of the steel sheet pile body 3 to be respectively inserted into the two locks 2, so as to avoid crushing of the steel sheet pile body 3 by multiple locks 2.

[0026] Further, in order to facilitate the synchronous inward or outward movement of the spiral tube 7 on the screw rod 6, refer to Figure 3As shown, the two screw tubes 7 have a first threaded hole 12 and a second threaded hole 15 with opposite thread directions at opposite ends, and the two ends of the screw rod 6 are respectively screwed into the first threaded hole 12 and the second threaded hole 15. Since the threads of the first threaded hole 12 and the second threaded hole 15 are opposite, when the screw rod 6 rotates, the two screw tubes 7 move closer to or farther away from each other on the screw rod 6, thereby facilitating the adjustment of the overall length of the screw rod 6 and the two screw tubes 7.

[0027] Further, in order to facilitate the rotational drive of the screw 6, refer to Figure 1-4 As shown, a plurality of levers 5 for rotational driving are also mounted on the screw rod 6, a mounting seat 4 is provided in the middle of the screw rod 6, and a plurality of levers 5 are respectively distributed in a circular array on the outer wall of the mounting seat 4. The plurality of levers 5 are arranged in a circular array on the screw rod 6 through the mounting seat 4, and the plurality of levers 5 are convenient for driving the screw rod 6 for rotational adjustment.

[0028] In the present utility model, combined with Figure 3 As shown, in this embodiment, a slot 10 is formed at the bottom of each holder 8 , and at least a portion of the top of the steel pipe pile body 1 is inserted into the slot 10 .

[0029] Combination Figure 2-3 As shown, each of the slots 10 is provided with a clamping plate 11 for clamping the steel pipe pile body 1, the outside of the holder 8 is provided with a mounting hole 13 for connecting the slots 10, the outside of the holder 8 is provided with an adjusting bolt 9 screwed in the mounting hole 13, and the clamping plate 11 is provided with a rotating groove 14, one end of the adjusting bolt 9 is rotatably installed in the rotating groove 14.

[0030] As mentioned above, when using the clamping slot 10 and the clamping plate 11 provided by the utility model, the clamping seat 8 is easily clamped on the steel pipe pile body 1 through the clamping slot 10. At this time, the adjusting bolt 9 is rotated to push the clamping plate 11 to one side of the steel pipe pile body 1 through the rotating groove 14, so that the steel pipe pile body 1 is clamped in the clamping plate 11 and the clamping slot 10, preventing the clamping seat 8 from being separated from the steel pipe pile body 1.

[0031] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
