Description

Technical Field

[0001] The utility model relates to the technical field of water conservancy projects, in particular to a trench excavation supporting device. Background Art

[0002] Trench excavation is a common construction link in the fields of civil engineering, municipal construction and underground pipeline laying. With the acceleration of urbanization, the depth and width of trench excavation continue to increase, which puts higher requirements on safety support during the excavation process.

[0003] Traditional trench excavation support methods mostly use wooden or steel support structures. These methods not only have low construction efficiency, but the support effect is greatly affected by environmental factors (such as soil quality, groundwater level, etc.), and there are safety hazards. In addition, traditional support devices often lack flexibility and are difficult to adapt to the excavation needs of trenches of different shapes and sizes. The installation and disassembly of the support structure is time-consuming, which increases the construction period and cost. Therefore, a trench excavation support device is proposed.

A drill bit 11 that fits the groove surface is rotatably installed on the outer end of the fixed bottom frame 1.

[0033] It should be noted that the support plate 3 is tightly connected to the fixed plate 9 through the locking shaft 6, ensuring the stability and firmness of the support structure during the trench excavation process. This design effectively prevents soil collapse caused by insufficient support and ensures the safety of construction workers and the surrounding environment.

[0034] In this embodiment, a row of limit slots are provided on the outer surface of the positioning slide plate 2, a positioning slot block 4 is fixedly installed at the bottom of the support plate 3, the positioning slot block 4 is slidably installed on the top of the positioning slide plate 2, and the outer side of the positioning slot block 4 is threadedly connected to a limit column 14, and the limit column 14 can be clamped on the inner side of the limit slot.

[0035] It should be noted that the sliding installation of the positioning slot block 4 on the positioning slide plate 2 ensures that the support plate 3 can be accurately positioned at the desired position. The limit clamping column 14 is connected to the outer side of the positioning slot block 4 through a thread and can be clamped in the limit clamping slot of the positioning slide plate 2. This locking mechanism effectively prevents the support plate 3 from accidentally moving or tilting during the excavation process, thereby enhancing the stability and reliability of the support structure.

The tight fit can also reduce the safety hazards caused by insufficient support and improve the construction safety.

[0038] In this embodiment, expansion positioning grooves 12 are provided on both the front and rear sides of the clamping plate 5, and another group of support plates 3 can be clamped with adjacent clamping plates 5.

[0039] It should be noted that through the design of the expansion positioning grooves 12, the support device can be flexibly expanded according to the actual width of the groove. When encountering a wider groove, the number of support plates can be conveniently increased to ensure that the entire side wall of the groove can be fully supported.

[0040] The clamping component includes a rotating bolt 7. The rotating bolt 7 is arranged at the connection of the clamping shaft 6 and the fixing plate 9. A threaded telescopic shaft 8 is rotatably installed at one end of the rotating bolt 7 close to the fixing plate 9.

This design enables the entire clamping component to be adjusted in height according to specific requirements, increasing the flexibility and adaptability of use.

[0043] When the rotating bolt 7 is tightened, it can be firmly fixed on the threaded rod 13, thus ensuring the stability and reliability of the clamping component. This fixing method is not only simple and fast but also can effectively prevent loosening or falling off during use.

[0044] The beneficial effects of the above embodiment are as follows:

[0045] By providing expansion positioning grooves 12 on both the front and rear sides of the clamping plate 5, adjacent support plates 3 are clamped together to form a longer support structure. At the same time, the threaded connection between the rotating bolt 7 and the threaded rod 13 and the threaded connection between the threaded telescopic shaft 8 and the fixing plate 9 make the connection between the support plates 3 not only stable but also the position of the support plates can be finely adjusted by adjusting the rotating bolt 7, further enhancing the flexibility of the support device.

[0046] Through the design of the sliding installation and matching limit card slots and limit card posts 14 between the positioning slide plate 2 and the support plate 3, the support plate 3 can be accurately positioned at the required position and fixed by means of the limit card posts 14, preventing the accidental movement of the support plate during construction and improving the stability of the support structure.
