Description

Technical Field

[0001] The utility model relates to the technical field of building construction, and more particularly to an anti-collapse supporting structure for a deep foundation pit. Background Art

[0002] In the real estate and construction industries, deep foundation pit is a specialized term that refers to a deep pit excavated to support and protect underground structures during the construction of high-rise buildings or other large structures. The construction of a deep foundation pit is a critical step in construction projects, involving complex technical and management issues. Deep foundation pits typically exceed 5 meters in depth, and excavation at this depth requires strict technical specifications and safety measures to ensure safety during construction and structural stability. The design and construction of deep foundation pits require consideration of multiple factors, including geological conditions, groundwater levels, the surrounding environment, and expected loads.

[0003] Deficiencies of existing technology: Under existing technology, in order to prevent the collapse of deep foundation pits, a commonly used method is to install multiple bored piles on the pit wall of the deep foundation pit. To ensure the stability of the bored piles, the staff will connect and fix the multiple bored piles with anchor cables. This method can improve the anti-collapse ability of the bored piles to a certain extent, but the bored piles themselves still lack a certain supporting force, and their stability and strength are still insufficient.

A fixed shaft is fixedly connected to the moving frame, one end of the connecting rod is rotatably connected to the surface of the fixed shaft, and the other end of the connecting rod is fixedly connected to the surface of the rotating rod.

[0010] Preferably, a threaded rod is provided between two adjacent moving frames, and both ends of the threaded rod are rotatably connected to the support plate. The threaded rod passes through the connecting bar, and a sleeve is provided at the top and bottom of the connecting bar.

In addition, the forms of the various structures recorded in the following embodiments are merely examples. The anti-collapse support structure for deep foundation pits involved in the present invention is not limited to the various structures recorded in the following embodiments. All other implementations obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0023] The utility model provides an anti-collapse support structure for a deep foundation pit, comprising a base plate 1 and cast-in-place piles 3, a support plate 2 being rotatably installed on the top of the base plate 1, a support assembly 4 being installed between the base plate 1 and the support plate 2, the support plate 2 being used to support the cast-in-place piles 3, and the support assembly 4 being used to provide supporting force for the support plate 2.

[0024] The support assembly 4 includes a mounting frame 41 and a built-in groove 44. The mounting frame 41 is fixedly installed on the top of the base plate 1. The built-in groove 44 is opened on one side of the support plate 2. There are multiple built-in grooves 44 evenly arranged. A moving frame 42 is slidably installed in the built-in groove 44. A connecting rod 43 is installed between the moving frame 42 and the mounting frame 41. The two adjacent moving frames 42 are fixedly connected by a connecting strip 46.

[0025] Furthermore, a fixing bar 21 is fixedly connected to the bottom of the support plate 2, and a rotating rod 22 is fixedly connected inside the fixing bar 21. The two ends of the rotating rod 22 are rotatably connected to the bottom plate 1. The staff can push the support plate 2 to rotate the support plate 2 around the axis of the rotating rod 22.

[0026] Furthermore, a guide rod 45 is provided in the built-in groove 44, and both ends of the guide rod 45 are fixedly connected to the groove wall of the built-in groove 44, and two guide rods 45 are provided in each built-in groove 44. The moving frame 42 is sleeved on the surface of the guide rod 45, and the moving frame 42 and the guide rod 45 form a sliding guide cooperation along the axis direction of the guide rod 45. A rotating rod 411 is rotatably installed on the mounting frame 41, and a plurality of connecting rods 43 are provided corresponding to the moving frame 42. A fixed shaft 421 is fixedly connected to the moving frame 42, and one end of the connecting rod 43 is rotatably connected to the surface of the fixed shaft 421, and the other end of the connecting rod 43 is fixedly connected to the surface of the rotating rod 411. When the support plate 2 rotates around the axis of the rotating rod 22, the moving frame 42 can slide synchronously along the guide rod 45, and the connecting rod 43 can rotate around the axis of the rotating rod 411.

[0027] Furthermore, a threaded rod 47 is provided between two adjacent moving frames 42. The two ends of the threaded rod 47 are rotatably connected to the support plate 2. The threaded rod 47 passes through the connecting bar 46. There is no connection relationship between the connecting bar 46 and the threaded rod 47. A sleeve 48 is provided at the top and bottom of the connecting bar 46. The inside of the sleeve 48 is threadedly connected to the surface of the threaded rod 47. The staff can screw the sleeve 48 to make the sleeve 48 move along the axial direction of the threaded rod 47.

[0028] Furthermore, multiple bored piles 3 are evenly arranged, and a receiving plate 31 is provided on the surface of the bored pile 3. The receiving plate 31 is fixedly connected to the bored pile 3 by bolts 32. The bored pile 3 is an existing technology in the field of construction and will not be described in detail here. The receiving plate 31 can interfere with the support plate 2, thereby realizing the support of the bored pile 3 by the support plate 2.

[0029] Furthermore, a positioning rod 11 is fixedly connected to the bottom of the base plate 1, and a plurality of positioning rods 11 are evenly arranged. The positioning rods 11 can be inserted into the bottom of a deep foundation pit.

[0030] The working principle of the present utility model: During actual work, the staff inserts the positioning rod 11 into the bottom of the deep foundation pit to fix the position of the bottom plate 1, and then pushes the supporting plate 2 to rotate the supporting plate 2 around the axis of the rotating rod 22. While the supporting plate 2 rotates, the moving frame 42 slides synchronously along the guide rod 45, the connecting rod 43 rotates around the axis of the rotating rod 411, and the connecting bar 46 also moves along the threaded rod 47. When the supporting plate 2 and the receiving plate 31 on the bored pile 3 conflict with each other, the staff screws the sleeve 48 to make the two sleeves 48 on each threaded rod 47 move toward the direction close to the connecting bar 46, and the connecting bar 46 is restricted between the two sleeves 48 and cannot move. At this time, the position of the supporting plate 2 is fixed, and the supporting plate 2 supports the bored pile 3.
