[0032] The specific implementation of the present invention is described in detail below in conjunction with specific embodiments.

[0033] In one embodiment, see Figure 1 to Figure 3 , a support frame for underground engineering construction is provided, comprising a vertical support frame 11, a top support base plate 12 arranged on the vertical support frame 11, and a plurality of side wing support assemblies 13 installed on the top support base plate 12, and a frame-type support top frame 14 is supported and installed on the top of each side wing support assembly 13; the main body of the frame-type support top frame 14 is a support frame box 21, and the support frame box 21 is a frame structure, and a frame box top frame 22 is arranged on the top of the frame of the support frame box 21, and a soil layer support assembly 23 is installed on the frame plate of the frame box top frame 22;

[0034] The wing support assembly 13 includes a mounting base 31, a hydraulic support assembly 32 mounted on the mounting base 31, and a support bracket 33 arranged on the hydraulic support assembly 32. The mounting base 31 is provided with two frame plates respectively mounted on both sides of the top support base plate 12, and the support bracket 33 is supported on the bottom of the frame plate of the support frame box 21; the mounting base 31 is rotatably mounted on the top support base plate 12, and a bottom support frame 34 and a synchronous driving member 35 arranged on the bottom support frame 34 are also fixedly mounted on the top support base plate 12.

The soil layer support assembly 23 is installed on the top frame 22 of the frame box at the top, which is used to directly bear and disperse the pressure from the upper soil layer to improve the pressure bearing capacity and adaptability of the support structure. The soil layer support assembly 23 is provided with a plurality of support components, and the synergistic effect of the support components can effectively disperse and transmit pressure to prevent structural damage or collapse caused by excessive pressure.

[0036] The wing support assembly 13 is used to support the support frame 21, and the mounting base 31 serves as the basis of the entire wing support assembly 13. Specifically, two mounting bases 31 are provided, which are respectively mounted on the frame plates on both sides of the top support base plate 12, and are fixedly connected to the support frame 21 through high-strength connectors to ensure its stability during work. In addition, the mounting base 31 adopts a rotatable mounting method to ensure that the wing support assembly can be flexibly turned and adjusted according to construction needs.

[0038] In one embodiment, see Figures 4 to 6 Based on the contents of the above embodiment, the relevant implementation structure of the soil support assembly 23 is designed as follows:

[0039] The side wing fixing plates 43 are arranged on both sides of the frame wall of the support frame 21, and the side wing supporting top plates 45 are installed on the upper sides of the side wing fixing plates 43 through the outward curved convex plates 44, and the support brackets 33 support and are fixed to the bottoms of the corresponding side wing fixing plates 43. The side wing fixing plates 43 are respectively connected to the installation of the side wing support brackets 33, thereby increasing the support range on both sides of the frame wall of the support frame 21 and enhancing the stability and safety of the support frame 21.

[0040] The soil layer support assembly 23 includes a straight plate support assembly 41 and a folding plate support assembly 42, and the straight plate support assembly 41 and the folding plate support assembly 42 are arranged on the frame box top frame 22. It should be noted that, in this embodiment, the number of the straight plate support assembly 41 and the folding plate support assembly 42 can be determined according to the specific construction environment of the underground project.

[0041] The straight plate supporting assembly 41 includes a side edge base plate 61 fixed on the frame box top frame 22, a straight plate adjusting rail 63 arranged on the side edge base plate 61, and a supporting straight plate 62 installed on the straight plate adjusting rail 63. The supporting straight plate 62 is slidably installed on the straight plate adjusting rail 63. A second adjusting cylinder 64 is also provided on the side edge base plate 61. A second adjusting rod 65 is installed at the pushing end of the second adjusting cylinder 64. The second adjusting rod 65 is connected to the plate body of the supporting straight plate 62.

[0042] Through the design of the straight plate adjustment track 63 and the second adjustment cylinder 64, the support straight plate 62 can adjust its support position as needed to adapt to soil pressure of different shapes and sizes, thereby improving the flexibility and adaptability of the support frame and enabling construction personnel to better cope with complex construction environments. The support straight plate 62 is made of high-strength, deformation-resistant material, and the auxiliary support frame 21 withstands the huge pressure from the soil layer above.

[0043] The folding plate support assembly 42 includes a frame corner track frame 51 and a frame edge track frame 52, the frame edge track frame 52 is arranged at the frame edge position of the frame box top frame 22, and the frame corner track frame 51 is arranged at the frame corner position of the frame box top frame 22; the folding plate support assembly 42 also includes a frame corner support top plate 53 and a frame edge support top plate 54, the frame corner support top plate 53 is installed on the frame corner track frame 51, and the frame edge support top plate 54 is installed on the frame edge track frame 52, the frame corner support top plate 53 is an L-shaped structure and is arranged along the frame corner of the frame box top frame 22; a first adjusting cylinder 55 is also provided on the frame edge of the frame box top frame 22, and a first adjusting rod 56 is installed at the movable end of the first adjusting cylinder 55, and the first adjusting rod 56 is connected to the plate body of the frame corner support top plate 53, and the frame edge support top plate 54 is integrally connected with the frame corner support top plate 53.

[0044] Through the design of the frame angle track frame 51, the frame side track frame 52 and the first adjustment cylinder 55, the folding plate support assembly 42 can adjust its position as needed to adapt to soil pressures of different shapes. The frame angle support top plate 53 adopts an L-shaped structural design and is arranged along the frame angle of the frame box top frame 22. This design not only enhances the stability of the structure, but also enables the top plate to better adapt to the complex and changeable soil pressure. The frame angle support top plate 53 and the frame side support top plate 54 are connected, and the two may not be plates of different heights to adapt to the uneven soil conditions. In this way, the frame side support top plate 54 complements the frame angle support top plate 53. The design greatly improves the flexibility and adaptability of the support frame, allowing construction personnel to better cope with complex construction environments.

[0045] During the specific implementation process, the construction personnel can first determine the number and position of the folding plate support assembly 42 according to the actual situation of the underground project. Then, the frame corner track frame 51 and the frame side track frame 52 are respectively installed at the frame corner and frame side positions of the frame box top frame 22. Next, the frame corner support top plate 53 and the frame side support top plate 54 are respectively installed on the corresponding track frames, and they are firmly connected together through an integrated connection. Finally, by adjusting the first adjustment cylinder 55, the frame corner track frame 51 and the frame corner support top plate 53 are adjusted to a suitable position and height to adapt to different construction environments and requirements.
