Description

Technical Field

[0001] The utility model relates to the technical field of civil engineering construction, in particular to a foundation pit construction structure. Background Art

[0002] Deep foundation pit excavation is a common construction process in modern urban development, especially with the increasing development and utilization of underground space. This process is growing in scale and depth, particularly with the increasing development and utilization of underground space. However, this comes with higher geological stability requirements and more complex challenges in protecting the surrounding environment. Traditional support methods, such as steel sheet piles and concrete retaining walls, often exhibit problems such as insufficient support rigidity and severe leakage in weak strata or high groundwater levels. This not only increases construction risks but also results in wasteful resources. Therefore, a new deep foundation pit support technology that comprehensively considers both economic benefits and environmental protection is urgently needed.

[0003] Patent publication number CN219157703U discloses a foundation pit construction protection structure, including a protective plate. The protection structure also includes an active support component, and the active support component includes: a first drive block, fixedly connected to the protective plate; a linkage hole, arranged on the first drive block, and an internal thread is provided on the inner wall of the linkage hole, which passes through the first drive block; a first sleeve, with an external thread on the circumferential wall, which is passed through the linkage hole, and the first sleeve is threadedly connected to the first drive block through the external thread and the internal thread.

[0004] In order to solve the problem that the existing protective structure can only support the left and right side walls of the foundation pit, and the front and rear side walls of the foundation pit cannot be supported, the existing technology is to use the protective structure of this application to set up symmetrically along the left and right sides of the foundation pit. There is no component between the left and right protective structures that will occupy the space of the foundation pit. In this way, space will be left in the middle position of the foundation pit to set up other protective structures for processing. However, there will be a situation where the protective structure cannot adjust the use angle, which leads to the problem that the protective structure has limitations. Utility Model Content

[0025] The present invention is further described in detail below with reference to the embodiments:

[0026] Example 1

[0027] like Figure 1-5 As shown, the utility model provides a foundation pit construction structure, including a device base 1, a support plate 2 is provided at the upper end of the device base 1, an adjustment mechanism 3 is provided at one end of the support plate 2, the adjustment mechanism 3 includes a main rod 31, and rotating rods 32 are fixedly connected on both sides of the main rod 31, one end of the main rod 31 is fixedly connected to a clockwise threaded rod 33, one end of the clockwise threaded rod 33 is threadedly connected to a first adjusting rod 34, the bottom end of the first adjusting rod 34 is fixedly connected to a first plug column 35, the other end of the main rod 31 is fixedly connected to a counterclockwise threaded rod 36, one end of the counterclockwise threaded rod 36 is threadedly connected to a second adjusting rod 37, and one end of the second adjusting rod 37 is fixedly connected to a second plug column 38.

[0028] In this embodiment, by inserting the first plug 35 into the first connecting column 18 and the second plug 38 into the second connecting column 25, the second connecting column 25, the main rod 31 and the first connecting column 18 are connected as a whole to support the support plate 2. The main rod 31 is rotated by the rotating rod 32 to rotate the clockwise threaded rod 33 and the counterclockwise threaded rod 36, so that the first adjustment rod 34 and the second adjustment rod 37 extend to the two ends of the main rod 31, thereby strengthening the supporting force of the support plate 2 and making the support more stable.

[0029] Example 2

[0030] like Figure 1-5As shown, on the basis of Example 1, the utility model provides a technical solution: preferably, the device base 1 includes a fixed ground nail 14, a first connecting shaft 16, and a first connecting member 17. A fixing hole 11 is provided at the upper end of the device base 1, and a connecting block 12 is fixedly connected to the other side of the upper end of the device base 1. A lower connecting plate 13 is fixedly connected to the upper end of the device base 1. The upper end of the fixed ground nail 14 is fixedly connected to the ground nail handle 15. The fixed ground nail 14 is plugged into the device base 1 through the fixing hole 11. Both ends of the first connecting member 17 are fixedly connected to the first connecting shaft 16.

[0035] The following is a detailed description of the working principle of the foundation pit construction structure.

[0036] like Figure 1-5 As shown, when the present structure is in use, the position of the device base 1 can be fixed by nailing the fixed ground nail 14 into the ground through the fixing hole 11, thereby preventing the device base 1 from being offset by the reaction force when it is supported by the support plate 2, resulting in invalid support of the support plate 2. By inserting the first plug 35 into the first connecting column 18 and the second plug 38 into the second connecting column 25, the second connecting column 25, the main rod 31 and the first connecting column 18 are connected as a whole, thereby supporting the support plate 2. By rotating the main rod 31 through the rotating rod 32, the clockwise screw The threaded rod 33 and the counterclockwise threaded rod 36 rotate, so that the first adjustment rod 34 and the second adjustment rod 37 extend to the two ends of the main rod 31, thereby strengthening the supporting force of the support plate 2 and making the support more stable. The angle between the support plate 2 and the device base 1 can be adjusted by setting the connecting shaft 21, so that the support plate 2 can support foundation pits at different angles. Through the setting of the second connecting shaft 23 and the first connecting shaft 16, in conjunction with the adjustment mechanism 3, the support plate 2 at different usage angles can be supported, which increases the practicality of the device.
