[0019] 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.

[0020] See also Figures 1 to 5The utility model provides a technical solution: a foundation pit support structure, including a main guard plate 1, a fixing plate 11 is installed at both sides of the top of the main guard plate 1, and cement nails 12 are movably screwed inside the two sets of fixing plates 11, the main guard plate 1 is fixedly installed with the top of the foundation pit by the two sets of fixing plates 11 and the two sets of cement nails 12, and the main guard plate 1 is fixedly installed with the top of the foundation pit by the two sets of fixing plates 11 and the two sets of cement nails 12. The main guard plate 1 is provided with installation grooves 13 at the bottom of both sides, and the inner walls of the two sides of the two sets of installation grooves 13 are provided with sliding grooves 14 at the bottom of the two sets of installation grooves 13. The positions of the two ends and one side are both open-type settings, electric push rods 15 are installed on the top inner walls of the two groups of mounting grooves 13, and mounting plates 16 are installed on the bottom ends of the two groups of electric push rods 15, sliders 17 are installed on both sides of the two groups of mounting plates 16, and magnet rods 18 are installed on the bottom ends of the two groups of mounting plates 16, one end of the slider 17 extends into the interior of the corresponding slide groove 14 and is slidably connected thereto, splicing holes 19 are opened at the bottom of the main guard plate 1 on both sides, and splicing rods 21 are movably spliced ​​inside the two groups of splicing holes 19.

[0021] The bottom ends of the two groups of splicing rods 21 are installed on the top of the splicing guard plate 2, and fixing holes 22 are opened on both sides of the top of the splicing guard plate 2. The outer diameter of the magnet rod 18 is adapted to the inner diameter of the corresponding fixing hole 22, and the magnet rod 18 and the fixing hole 22 are arranged correspondingly.

[0022] When in use, the main guard plate 1 can be fixedly installed at one side of the top of the foundation pit through two sets of fixing plates 11 and two sets of cement nails 12, so that the main guard plate 1 can be evenly distributed on the inner walls of both sides of the foundation pit. Figure 1As shown, at this time, the arrangement of several groups of main guard plates 1 can play a corresponding protective role on the inner walls on both sides of the foundation pit, and this arrangement method makes it possible for the bottom end of the foundation pit to be free of supporting structures, thereby facilitating normal construction for construction workers at the bottom end of the foundation pit. When the existing foundation pit needs to be dug deeper according to actual construction needs, after the deep digging operation is completed, the construction workers can align the two groups of splicing rods 21 arranged on the top of the splicing guard plate 2 with the splicing holes 19 opened on both sides of the bottom end of the corresponding main guard plate 1, thereby completing the preliminary positioning and installation between the splicing guard plate 2 and the corresponding main guard plate 1. After that, the user can align the two groups of splicing rods 21 arranged on the top of the splicing guard plate 2 with the splicing holes 19 opened on both sides of the bottom end of the corresponding main guard plate 1. The two groups of electric push rods 15 are started accordingly, so that under the operation of the two groups of electric push rods 15, the corresponding mounting plates 16 can move downward accordingly, so that the magnet rods 18 can move downward accordingly, so that the corresponding magnet rods 18 can respectively extend into the corresponding fixing holes 22 and perform corresponding adsorption and fixing settings with the bottom inner walls of the corresponding fixing holes 22, so that the top of the splicing guard plate 2 can be fixed to the bottom end of the corresponding main guard plate 1, and so on, the bottom ends of all main guard plates 1 can be correspondingly spliced ​​and installed with the tops of the splicing guard plates 2, so that the inner walls of the foundation pit after deep excavation can be effectively protected accordingly.
