AI Technical Summary
In existing technologies, the sleeve is prone to collision with the inner wall when inserted into the hole, making insertion difficult and affecting the accuracy of the test results.
The support plate assembly is connected by a spring hinge assembly. The support plate automatically expands within the hole and is fixed by a limiting assembly, reducing the probability of collision and enhancing the support effect.
It reduces the probability of hole collapse, improves the support effect and overall strength of the sleeve in the hole, and simplifies the installation process.

Abstract
Claims
1. A borehole collapse prevention support device for surveying, characterized by, include: The support assembly includes N support plates connected end to end in sequence. Two adjacent support plates are rotatably connected by a spring hinge assembly. Adjacent support plates and the first and last support plates are also connected by a limiting assembly. N is a natural number greater than or equal to 3.
2. The borehole collapse prevention support apparatus of claim 1, wherein: The cross-section of the support plate is arc-shaped, and multiple support plates have the same radius, and multiple support plates can be formed into a tube shape.
3. The borehole collapse prevention support apparatus of claim 2, wherein: The curvature of the multiple support plates increases sequentially from beginning to end.
4. The borehole collapse prevention support apparatus of claim 2 or 3, wherein: A first mounting seat is fixedly provided at the top of one end of the inner sidewall of the support plate, and a second mounting seat is fixedly provided at the upper part of the other end of the inner sidewall of the support plate. The second mounting seat is located below the first mounting seat. The first mounting seat of each support plate and the second mounting seat of the adjacent support plate are arranged coaxially. Both the first mounting seat and the second mounting seat are provided with prism-shaped through holes along the vertical direction. The limiting component includes a limiting rod that is fitted into the two upper and lower opposite through holes.
5. The anti-collapse support device for survey boreholes as described in claim 4, characterized in that: The limiting component also includes a limiting plate fixedly disposed at the other end of the outer side wall of the support plate, the limiting plate extending to the outer side of the other end of the support plate.
6. The borehole collapse prevention support apparatus of claim 5, wherein: The limiting plate has an arc-shaped cross-section, and the inner sidewall of the limiting plate can fit against the outer sidewall of the adjacent support plate.
7. The borehole collapse prevention support apparatus of claim 6, wherein: Multiple sets of spring hinge assemblies are arranged vertically between two adjacent support plates, and multiple sets of limiting plates are arranged vertically alternately.
