Description

Technical Field

[0001] The invention relates to the technical field of water conservancy and hydropower engineering slopes, and in particular to a water conservancy and hydropower engineering slope excavation pre-support device. Background Art

[0002] It involves the stability and safety issues during the slope excavation process. In water conservancy and hydropower projects, slope excavation is an important link, but the stability of the slope during the excavation process often faces challenges, and disasters such as landslides and collapses may occur, which will not only affect the progress of the project, but may also pose a serious threat to the safety of personnel and equipment. In order to solve this problem, technicians have developed a slope excavation pre-support device, which usually includes baffles, drilling components, fixed components and other parts, which can provide effective support before or during slope excavation.

[0003] According to a slope excavation pre-support device disclosed on the patent website (authorization announcement number: CN 219261049U), "a slope excavation pre-support device is described as "including a base plate, a vertical plate fixed to one side of the base plate, and a diagonal brace hinged to the side wall of the vertical plate close to the base plate; an extension plate is vertically slidably connected to the top of the vertical plate; an extension rod is fixed to the bottom of the extension plate; an extension groove that can be slidably connected to the extension rod is opened on the top surface of the vertical plate; and a fixing component that can be used to fix the extension rod is arranged around the extension groove."

[0004] In view of the above description, the applicant believes that there are the following problems:

[0005] During use of the utility model, when it is necessary to support a higher slope, the extension rod is pulled upward to increase the height of the extension plate relative to the vertical plate, and the extension rod is fixed by a fixing assembly, so that the purpose of increasing the support range can be achieved, thereby meeting the support needs of slopes of different heights. However, in actual use, in different environments, due to the different slope angles and the extension plate of the device being fixed to the base plate, it is impossible to adjust the appropriate slope protection angle according to the slope angle, and thus it is impossible to make the extension plate fit the slope, resulting in poor slope protection effect and the slope is prone to loosening during work.
