[0026] like Figure 1 to Figure 3 As shown, a deep foundation pit wall support assembly comprises:

[0027] The enclosure assembly is provided with two rows of enclosure assemblies, and the two rows of enclosure assemblies are arranged opposite to each other. Each row of enclosure assemblies includes an assembly pillar 1, and a plurality of assembly pillars 1 are provided, and the assembly pillars 1 are arranged in an array. Two clamping rails 101 are symmetrically arranged on each assembly pillar 1, and baffles 5 are clamped between two adjacent assembly pillars 1 in each row of enclosure assemblies through the clamping rails 101. When in use, each assembly pillar 1 is inserted into the soil and rocks at the bottom of the foundation pit, so that each assembly pillar 1 is arranged in an array, and then the baffles 5 are clamped between the opposite clamping rails 101 on the adjacent assembly pillars 1, so that the assembly forms an enclosure to cover the soil and rocks on the side wall of the foundation pit;

[0028] See also Figure 2 and Figure 3 , a reinforcement component is arranged between two rows of enclosure components, and the reinforcement component includes a stabilizing pillar 2, and a plurality of stabilizing pillars 2 are arranged in an array, and each stabilizing pillar 2 is located between the baffles 5 in the two rows of enclosure components; each stabilizing pillar 2 is provided with four hinged seats 201, and each hinged seat 201 is hingedly provided with a pulling rod 3, and each pulling rod 3 is provided with a pulling rod 2 4 through a support 301; each assembly pillar 1 is provided with two buckles 102, and each stabilizing pillar 2 is inserted into the soil and stone at the bottom of the foundation pit, and an assembly pillar 1 is arranged between two adjacent stabilizing pillars 2, and then each pulling rod 3 and each pulling rod 2 are connected. One end of each of the pull rods 1 3 and 4 is respectively clamped in the corresponding buckle 102, and the clamping end of each pull rod 1 3 and each pull rod 2 4 is in a dovetail shape, and the clamping groove of each buckle 102 is in a dovetail shape, so that after the clamping end of each pull rod 1 3 and each pull rod 2 4 is respectively clamped in the clamping groove on the corresponding buckle 102, the clamping end of the pull rod 1 3 and the pull rod 2 4 can be prevented from slipping out of the clamping groove on the buckle 102, thereby enhancing the clamping stability therebetween, so that each pull rod 1 3 and the pull rod 2 4 can finally be abutted against the corresponding assembly pillar 1 to support the enclosure assembly, thereby preventing the two rows of enclosure assemblies from being squeezed by soil and rocks and deforming toward the inside of the foundation pit or even collapsing;

[0029] When the clamping ends of each pulling rod 1 3 and each pulling rod 2 4 are respectively clamped in the clamping grooves on the corresponding buckles 102, the pulling rods 1 3 between two adjacent stable pillars 2 can be combined to form a rhombus shape; the two pulling rods 1 3 on the same stable pillar 2 and the corresponding pulling rods 2 4 arranged thereon can be combined to form a rhombus shape; each pulling rod 1 3 and the corresponding pulling rod 2 4 arranged on the pulling rod 1 3 and the corresponding baffle plate 5 can be combined to form an equilateral triangle shape. The rhombus structure formed by each pulling rod 1 3 and the rhombus structure formed by the corresponding pulling rod 1 3 and the corresponding pulling rod 2 4 can be used. The rods 1 3 and the corresponding pulling rods 1 3 and the corresponding pulling rods 2 4 can play a role of mutual traction and pulling, so that each pulling rod 1 3 and each pulling rod 2 4 are not easy to move and misalign, thereby enhancing the stability of each component; at the same time, the equilateral triangle structure formed by the corresponding pulling rods 1 3, the corresponding pulling rods 2 4 and the corresponding baffles 5 also has high stability, which enables the support strength of the entire reinforcement assembly to be enhanced under the action of the diamond structure combined with the equilateral triangle structure, thereby preventing the assembly pillar 1 from tilting toward the inside of the foundation pit when a certain assembly pillar 1 is squeezed, thereby improving the support effect on the two rows of enclosure components.

[0030] See also Figure 1 and Figure 2 Each pulling rod 1 3, each hinge seat 201 and each pulling rod 2 4 in the reinforcement component are arranged with two layers in the vertical direction. Arranging them into two layers enables each assembly pillar 1 to have a supporting force point at the upper and lower parts, thereby enhancing the supporting effect of the assembly pillar 1.
