[0002] Currently, during the excavation of deep trenches, it is often necessary to adopt supporting structures to prevent the soil walls on both sides of the trench from collapsing.

[0003] Traditional support devices typically include sheet piles, earth wall supports, beams, etc., but these methods often have the following disadvantages: (1) complex installation: traditional support systems require a lot of manual operation and have a long construction period; (2) poor adaptability: as the depth and width of the trench change, the support structure is difficult to adapt to different excavation requirements; (3) difficult disassembly: the disassembly of traditional support structures is cumbersome and affects the construction progress.

[0004] Therefore, this application is hereby submitted. Summary of the Invention

[0023] The support device for deep trench excavation disclosed in this embodiment uses multiple support modules that can be detachably stacked to adapt to the trench depth by selecting the appropriate number of modules. Each support module includes a pair of support walls 10, which abut against the side walls of the trench to provide support and positioning. Multiple hydraulic telescopic rods 20 are connected at both ends to the two support walls 10. The hydraulic extension of the telescopic rods 20 compresses the two support walls 10 from the inside out, pressing them firmly against the side walls of the trench, thus securing the trench. The trench walls provide lateral support, and the length of the hydraulic telescopic rod 20 can be adaptively adjusted according to trenches of different widths. By setting a slide rail 11, the end of the hydraulic telescopic rod 20 slides and engages with the slide rail 11, allowing the height of the hydraulic telescopic rod 20 to be adjusted according to actual conditions. By setting a fixing member 30, the end of the adjusted hydraulic telescopic rod 20 can be detachably and fixedly connected to the slide rail 11, ensuring the stability of the entire device. Through the cooperation of the above features, this support device for deep trench excavation can effectively solve the problem of poor adaptability of existing support devices to trench depth and width, and is simple and convenient to install and disassemble.

[0027] In order to position the rotation angle of the hydraulic telescopic rod 20 so that the through hole 211 and the connecting hole 113 are arranged in parallel, the slider 21 is prismatic and is coaxially arranged with the hydraulic telescopic rod 20. The side wall of the slider 21 is provided with at least a pair of parallel sliding surfaces. The distance between the two sliding surfaces matches the distance between the pair of guide plates 111. The through hole 211 perpendicularly penetrates the sliding surface.

[0028] To improve the stability of the support structure, each of the support wall 10 is provided with two slide rails 11, which are symmetrically arranged on both sides of the width direction of the support wall 10.

[0029] To provide a specific explanation of the detachable connection structure between the support modules, the aforementioned support device for deep trench excavation also includes multiple pins 40, the two ends of which can be detachably inserted between two pairs of guide plates 111, so that the two support modules can be detachably stacked through the two pins 40.

[0030] With the above setup, the two ends of the pin 40 are inserted into the upper and lower slide rails 11 respectively, thereby fixing the two support modules together as one unit.

[0031] To further explain the specific structure of the pin 40 so that the shape of the pin 40 matches that of the slide rail 11, thereby further improving the structural stability after connection, the pin 40 is in the shape of a cuboid strip, the width of the pin 40 matches the distance between the pair of guide plates 111, and the thickness of the pin 40 matches the width of the guide plate 111.

[0032] To further improve the stability of the connection between the pin 40 and the slide rail 11, the side wall of the pin 40 is evenly spaced with a plurality of fixing holes 41 along the length direction, and the outer diameter of the fixing member 30 matches the diameter of the fixing holes 41 and the through hole 211.
