[0020] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. These drawings are simplified schematic diagrams that only illustrate the basic structure of the present invention in a schematic manner, and therefore only show components related to the present invention.

[0021] like Figure 1 、 Figure 2 and Figure 3 As shown, a pile foundation pit support structure includes: a supporting structure and an adjustment structure movably connected together, the supporting structure includes: two upper fixed plates 1 and two lower fixed plates 2 arranged symmetrically, a number of adjusting rod groups 3 are arranged between the two upper fixed plates 1 and between the two lower fixed plates 2, the adjusting rod group 3 includes: a rotating sleeve 301 and a fixed screw rod 302 threadedly connected to both ends of the rotating sleeve 301, the fixed screw rod 302 is hingedly connected to a docking base 303, a support rod group 4 is arranged between the upper fixed plate 1 and the lower fixed plate 2, and the two ends of the support rod group 4 are respectively hingedly connected to the upper fixed plate 1 and the lower fixed plate 2; through the slopes on both sides of the pile foundation pit, the length of the adjusting rod group 3 between the two upper fixed plates 1 and the length of the adjusting rod group 3 between the two lower fixed plates 2 can be flexibly adjusted to ensure that the support structure can adapt to pile foundation pits with different slopes, thereby effectively improving the practicality of the support structure. Furthermore, because the fixed screw 302 is hingedly connected to the docking base 303, and the upper and lower fixing plates 1 and 2 are hingedly connected via the support rod assembly 4, the two assembly base plates 6 can be adapted to complex slopes of varying gradients within the same pile foundation pit, further enhancing the practicality of the overall support structure.

[0022] In a preferred embodiment of the present invention, a plurality of docking blocks 11 are arranged in an array on the inner side surfaces of the upper fixing plate 1 and the lower fixing plate 2, and positioning holes are provided on the sides of the docking blocks 11. The positioning holes cooperate with the docking base 303 to flexibly disassemble the adjustment rod group 3. Moreover, when the length of the adjustment rod group 3 needs to be fine-tuned in the later stage, the length of a single adjustment rod group 3 can be gradually adjusted, and the overall design is more reasonable.

[0023] like Figure 4As shown, the adjustment structure includes: two rotating rods 5 hinged together, the two rotating rods 5 are hingedly connected to the assembly base plate 6 and the movable plate 7 respectively, two sliders 8 are symmetrically arranged on the top surface of the assembly base plate 6 and the bottom surface of the movable plate 7, the sliders 8 are hingedly connected to the rotating rods 5 respectively, and the bottom surface of the movable plate 7 is integrally provided with an assembly block 9, the assembly block 9 is rotatably connected to the transmission screw 10, two screw threads with opposite spiral directions are symmetrically arranged at both ends of the transmission screw 10, and the transmission screw 10 is threadedly connected to the sliders 8, the top surface of the assembly base plate 6 and the bottom surface of the movable plate 7 are provided with guide rail grooves 13, and the guide rail grooves 13 are slidably connected to the sliders 8. By setting the adjustment structure below the lower fixed plate 2, the height state of the adjustment structure itself can be changed according to the depth of the pile foundation pit, so as to better support the support structure for installation and positioning, ensure that the support structure is accurately installed in the specified position, and effectively improve the accuracy and convenience of the support structure during installation.

[0024] In a preferred embodiment of the present invention, a plurality of fixing cones 12 are arranged in an array on the outer side surfaces of the upper fixing plate 1 and the lower fixing plate 2. When the upper fixing plate 1 and the lower fixing plate 2 support the pile foundation pit, the fixing cones 12 can assist in limiting the position, effectively preventing the upper fixing plate 1 and the lower fixing plate 2 from moving, and improving the stability of the overall support structure.

[0025] The working principle of the present invention is as follows: according to the depth of the pile foundation pit, the transmission screw 10 is rotated forward, and the slider 8 moves relative to the transmission screw 10 to increase the height state of the adjustment structure itself, and the lower fixed plate 2 is placed above the movable plate 7. The rotating sleeve 301 in each adjusting rod group 3 is rotated forward respectively, and the adjusting rod group 3 is extended accordingly, holding the two upper fixed plates 1 and the two lower fixed plates 2, so that the outer side surfaces of the upper fixed plate 1 and the outer side surfaces of the lower fixed plates 2 are both close to the slope of the pile foundation pit. At the same time, the fixing cone 12 is completely embedded in the soil to assist in limiting the upper fixed plate 1 and the lower fixed plate 2. After the support structure is fixed, the transmission screw 10 is rotated in the opposite direction to remove the overall adjustment structure.

[0026] The above description is based on the ideal embodiment of the present invention. Based on the above description, relevant personnel can make various changes and modifications without departing from the technical scope of the present invention. The technical scope of the present invention is not limited to the content of the specification, but must be determined according to the scope of the claims.
