DETAILED DESCRIPTION OF THE EMBODIMENTS

[0022] Next, the technical solutions in the embodiments of the utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the utility model. Obviously, the described embodiments are only a part of the embodiments of the utility model, rather than all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the utility model.

[0023] Please refer to Figures 1-4, the present utility model provides a technical solution: a positioning bracket for L-shaped sheet pile construction, mainly composed of a positioning steel pin 1, a horizontal limiting frame 2, and a support frame 3. Among them, before placing the positioning bracket, a pile driver is required to drive the first V-shaped sheet pile 4, and then, according to the laying trajectory of several V-shaped sheet piles 4, the positioning steel pin 1 is driven into the stable soil layer. After these two fulcrums are determined, the entire positioning bracket is placed on the first driven V-shaped sheet pile 4 and the driven positioning steel pin 1. The top of the positioning steel pin 1 is provided with a reinforcing connecting plate 11, and the reinforcing connecting plate 11 can support the horizontal limiting frame 2. A limiting hole 21 is reserved in the middle of the horizontal limiting frame 2, and the top end of the positioning steel pin 1 is located in the limiting hole 21. The first driven V-shaped sheet pile 4 supports the support frame 3. When driving the subsequent multiple V-shaped sheet piles 4, they are inserted into the limiting hole 21 and then driven into the soil layer downward. The limiting hole 21 restricts and limits the driving process of the V-shaped sheet pile 4, so that the V-shaped sheet pile 4 can be vertically driven into the soil layer;

[0024] On the left and right sides of the horizontal limiting frame 2, a first limiting hole 22 and a second limiting hole 23 are respectively provided. The first limiting hole 22 and the second limiting hole 23 are fixed by a connecting fixing rod 24. Fixing the first limiting hole 22, the second limiting hole 23 and the connecting fixing rod 24 can strengthen the stretching and fixing effect of the horizontal limiting frame 2.

[0025] In addition, the support frame 3 includes a second limiting rod 31 connected to the other end of the horizontal limiting frame 2. A first limiting rod 32 is slidably connected inside the second limiting rod 31. The tops of the first limiting rods 32 are commonly connected to a cross bar 33. The second limiting rod 31 also reserves a limiting hole 21. The two limiting holes 21 are communicated. The already constructed sheet pile is located inside the limiting hole 21, and its top end supports the cross bar 33. A plurality of first pin holes 34 are reserved on both sides of the second limiting rod 31, and a plurality of second pin holes 35 are reserved on both sides of the first limiting rod 32. A pin shaft rod 36 is commonly inserted into the first pin holes 34 and the second pin holes 35;

[0026] The height of the support frame 3 can be adjusted. During the adjustment process, the pin shaft rod 36 is pulled out, and the height of the first limiting rod 32 inside the second limiting rod 31 is adjusted, so that the height of the entire support frame 3 can be changed. After adjustment, the pin shaft rod 36 is reinserted into the corresponding first pin holes 34 and second pin holes 35.
