[0021] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments.

[0022] The present embodiment includes a plurality of identical right-angled trapezoidal blocks 1, which are wide at the top and narrow at the bottom. Preferably, the width of the upper surface of the right-angled trapezoidal blocks 1 is between 30-40 cm, and the width of the lower surface is between 1-3 cm. The plurality of right-angled trapezoidal blocks 1 are evenly spaced, and the spacing between adjacent right-angled trapezoidal blocks 1 is equal. An L-shaped plate 2 is welded on the upper surface of the plurality of right-angled trapezoidal blocks 1, and the L-shaped plate 2 fixes and connects the plurality of right-angled trapezoidal blocks 1 together. The size of the L-shaped plate 2 is preferably consistent with the size of the plurality of right-angled trapezoidal blocks 1 after being connected and combined. In addition to connecting the plurality of right-angled trapezoidal blocks 1 together, the L-shaped plate 2 can also facilitate the taking of the right-angled trapezoidal blocks 1. A circular hole A3 is provided on the bottom surface of each right-angled trapezoidal block 1, and the circular hole A3 vertically penetrates the right-angled trapezoidal block 1 and the upper L-shaped plate 2 upward. In the present embodiment, the right-angled trapezoidal block 1 is preferably a closed body, which is hollow inside, and the right-angled trapezoidal block 1 is welded from steel plates. In the drawings of this embodiment, there are two right-angled trapezoidal blocks 1.

[0023] This embodiment also includes a right-angled trapezoidal shell 4, which corresponds to the right-angled trapezoidal block 1. The right-angled trapezoidal shell 4 is narrow at the top and wide at the bottom. The right-angled trapezoidal shell 4 is a non-enclosed body, and the upper end of the right-angled trapezoidal shell 4 is open. The side opposite to the vertical rectangular surface of the right-angled trapezoidal shell 4 is also open. The internal space of the right-angled trapezoidal shell 4 is evenly divided by a plurality of right-angled trapezoidal plates 5, and the thickness of the right-angled trapezoidal plates 5 is equal to the spacing between adjacent right-angled trapezoidal blocks 1. A plurality of right-angled trapezoidal blocks 1 can be inserted one by one from top to bottom into the divided space inside the right-angled trapezoidal shell 4, and the right-angled trapezoidal plates 5 can just be inserted into the gap between adjacent right-angled trapezoidal blocks 1. Preferably, the right-angled trapezoidal shell 4 is welded from a steel plate with a thickness of 3 mm. A plurality of circular holes B6 corresponding to the circular holes A3 are provided on the bottom surface of the right-angled trapezoidal shell 4, and long bolts 7 vertically pass through the circular holes A3 and B6 to connect the right-angled trapezoidal block 1 with the right-angled trapezoidal shell 4, and nuts 8 are provided above and below the long bolts 7. Preferably, the long bolts 7 are 60 cm long.

[0024] Construction process: The number of right-angle trapezoidal blocks 1 is determined according to the length of the gap between the steel sheet pile and the surrounding purlin. Multiple devices of the present invention can be manufactured to select according to the length of the gap between the steel sheet pile and the surrounding purlin. When the gap between the steel sheet pile and the surrounding purlin is small, for example, the gap is within 5 cm, the right-angled trapezoidal shell 4 of the present invention may not be used, and the right-angled trapezoidal block 1 may be directly inserted from above the gap between the steel sheet pile and the surrounding purlin, and hammered and tightened with a tool such as a hammer; when the gap between the steel sheet pile and the surrounding purlin is large, the right-angled trapezoidal shell 4 is first placed below the gap between the steel sheet pile and the surrounding purlin, and then the right-angled trapezoidal block 1 is placed above the gap between the steel sheet pile and the surrounding purlin, and the right-angled trapezoidal block 1 is inserted into the space separated by the right-angled trapezoidal shell 4, and hammered up and down to tighten, and the long bolt 7 is passed from bottom to top through the circular hole B6 and the circular hole A3, and the upper and lower nuts 8 are tightened, and the right-angled trapezoidal block 1 and the right-angled trapezoidal shell 4 are socketed together and tightened in the gap between the steel sheet pile and the surrounding purlin. Of course, when the gap between the steel sheet pile and the surrounding purlin is small, the right-angled trapezoidal block 1 and the right-angled trapezoidal shell 4 can also be used at the same time.

[0025] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit them. Those skilled in the art should understand that they can still modify the technical solutions described in the above embodiments, or replace some of the technical features therein with equivalents. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the embodiments of the present invention.
