Description

Technical Field

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

[0002] Construction engineering refers to the engineering entity formed by the construction of various types of buildings and their ancillary facilities and the installation of supporting lines, pipelines, and equipment. "Buildings" refer to projects with roofs, beams, columns, walls, foundations, and internal spaces that can meet people's needs for production, living, learning, and public activities. Since buildings require foundation pits, the slope coefficient of the slope is greatly affected when the foundation pit is excavated, which will inevitably affect the surrounding environment, and this requires the use of a new deep foundation pit slope support structure.

[0003] The prior art document CN212452695U provides a foundation pit retaining structure, which includes a slope, a plurality of anchor holes are provided on the slope, a side of the slope away from the deep foundation pit is inserted with an I-shaped steel, a plurality of rectangular holes are provided on the I-shaped steel, an anchor is inserted into the anchor hole, one end of the anchor extends out of the slope, a V-shaped hook is provided on the other end, burrs are evenly provided on the surface of the anchor, a steel pipe is connected between the ends of two adjacent anchors extending out of the slope, and a baffle is connected between the steel pipes. The utility model enhances the overall stability of the deep foundation pit slope support structure, can avoid the slope from sliding and instability, and thus eliminates the potential safety hazards of the foundation pit project.

[0004] The above-mentioned equipment is a steel pipe connected between the ends of the slope through two sets of anchor rods. Since baffles are connected between the steel pipes, the slope can be prevented from sliding and becoming unstable when encountering rain or excessive external pressure near the upper end of the slope, thereby eliminating potential safety hazards in foundation pit projects. However, when installing the equipment, the fixed structure is inserted into the soil layer and concrete is poured. The installation steps are relatively cumbersome, and the fixed structure will inevitably loosen during the solidification of the concrete, which requires staff to improve their equipment. Utility Model Content

[0005] Therefore, the technical problem to be solved by the utility model is to overcome the problem that the installation steps of a foundation pit retaining structure in the prior art are relatively complicated, thereby providing a foundation pit retaining structure.

[0006] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0007] A foundation pit retaining structure, comprising:

[0008] A fixed rod, the fixed rod is rotatably connected to a threaded rod, the surface of the threaded rod is threadedly connected to a slider, the surface of the slider is provided with a fixed block, the inner wall of the fixed block is rotatably connected to a support rod, one end of the support rod is rotatably connected to a support plate, and one side of the support plate is rotatably connected to the surface of the fixed rod, one end of the threaded rod is provided with a handwheel, and one side of the handwheel is rotatably connected to one end of the fixed rod.

[0009] As an optional technical solution, a ring is provided on the surface of the fixing rod, a first connecting plate is provided at the bottom of the ring, a rotating shaft is provided at the bottom of the first connecting plate, and a second connecting plate is rotatably connected to the surface of the rotating shaft.

[0010] As an optional technical solution, a card slot is provided on one side of the first connecting plate, and a card block is provided on one side of the second connecting plate, and the surface of the card block overlaps the inner wall of the card slot.

[0011] As an optional technical solution, a thread groove is provided on one side of the inner wall of the fixing rod, and a connecting component is threadedly connected to the inner wall of the thread groove.

[0012] As an optional technical solution, a plug is provided on one side of the connecting assembly, and one side of the plug is rotatably connected to one side of the fixing rod.

[0013] As an optional technical solution, movable grooves are provided on both sides of the fixing rod, and a first rotation groove is provided on the inner wall of the fixing rod.

[0014] As an optional technical solution, second rotation grooves are opened on both sides of the support plate, and both sides of the second rotation grooves are overlapped with the inner wall of the fixing rod.

[0015] The utility model technical solution has the following advantages:

[0016] 1. The utility model drives the threaded rod to move by rotating the hand wheel, and the movement of the threaded rod drives the slider on the surface to move, and the movement of the slider drives the surface fixed block to move, and the movement of the fixed block drives the bottom of the support rod to move, and the movement of the bottom of the support rod causes the support rod to tilt, and after the support rod is tilted, the support plate is pushed out of the movable groove. Since one side surface of the support plate is inclined, after the support plate is pushed out, the fixing rod is pulled toward the outside of the soil so that the other side of the support plate can contact the back soil layer, thereby fixing the equipment in the soil layer. The equipment does not need to be fixed with other equipment, and the installation structure can provide a better fixing effect for the equipment, and the expansion angle of the support plate can be adjusted by rotating the threaded rod, so that the support plate can be adjusted according to the thickness of the soil.

[0017] 2. The utility model fixes the equipment to the slope and then opens the second connecting plate through the rotating shaft, so that the first connecting plate and the second connecting plate are unfolded. When it is necessary to climb to the slope surface to work, the grooves on the surfaces of the first connecting plate and the second connecting plate can be stepped on to climb to the slope surface. This structure is convenient for the staff to work on the slope surface, and the connecting plates can be stored through the blocks and the slots. The unfolded connecting plates can protect the slope surface and effectively prevent some sand and stones from rolling down. BRIEF DESCRIPTION OF THE DRAWINGS
