Description

Technical Field

[0001] The utility model relates to the technical field of engineering construction, and particularly relates to a deep foundation pit slope support structure. Background Technique

[0002] Foundation pit maintenance is a method for developing and utilizing underground space and constructing various underground buildings such as multi-story basements, subways, and underground commercial streets. There are gravity-type mixing pile retaining walls, diaphragm walls, pile-type retaining walls, etc. It is not only necessary to ensure the stability of the foundation pit and the safety and convenience of operations inside the pit, but also to control the soil displacement at the bottom and outside the pit within a certain range to ensure the normal use of adjacent buildings and municipal facilities. Deep foundation pit slope support is a support, reinforcement, and protection measure for the side walls of the foundation pit and the surrounding environment to ensure the safety of underground structure construction and the surrounding environment of the foundation pit. Usually, a support structure can be used to strengthen the structural strength of the slope. During the installation and use of the existing deep foundation pit slope support structure, the slope can be supported, but generally, with the increase of the service time, certain deformation occurs, and after the deformation occurs, it will directly lead to a decrease in the supportability of the reinforcement structure, and there are often certain potential safety hazards. Content of the Utility Model

[0003] The purpose of the utility model is to provide a deep foundation pit slope support structure to solve the problems raised in the above background technique.

[0004] To achieve the above purpose, the utility model provides the following technical solution: A deep foundation pit slope support structure includes a sleeve shaft, a fixed seat, and two baffles. The top of the fixed seat is installed with a threaded rod through a bearing. The top of the threaded rod is installed with a limit seat. The outer part of the threaded rod is movably provided with a sleeve shaft. The two sides of the sleeve shaft are installed with connecting rods through rotating shafts. One end of the connecting rod is installed with a stress seat through a rotating shaft. One side of the stress seat is fixedly installed with a baffle. The inside of the baffle is installed with reinforcing ribs.

[0005] Preferably, a ground plug is installed at the bottom of the fixed seat, and fixing bolts are installed on both sides of the fixed seat.

[0006] Preferably, a turntable is arranged below the outer part of the threaded rod, and anti-slip lines are arranged on the outer part of the turntable.

[0007] Preferably, a reflective strip is installed outside the reinforcing ribs.

[0008] Preferably, fixing bolts are installed at both ends of the baffle.

[0009] In summary, this application includes the following beneficial technical effects:

[0010] By using the cooperation of the threaded rod, the fixed seat and the baffle, when it is necessary to improve the supporting force of the device on the slope, the threaded rod can be rotated. By rotating the threaded rod, the movable sleeve shaft can move vertically. When the movable sleeve shaft moves vertically downward, the supporting force on the baffle will be increased through the connecting rod, and the supporting force of the device can be adjusted, which can avoid the deformation of the device due to long-term use, and then lead to the attenuation of the supporting force of the device. By continuous adjustment, the supportability of the reinforcement structure can be maintained, and the practicability of the device is improved. BRIEF DESCRIPTION OF THE DRAWINGS

[0016] The following further describes the present application in detail Figures 1-4 in conjunction with the attached

[0017] It should be noted that the drawings are schematic and not drawn to scale. For the sake of clarity and convenience in the figure, the relative dimensions and ratios of the parts shown in the figure are exaggerated or reduced in size for illustration, and any dimensions are only exemplary and not limiting. In addition, the same reference numerals are used for the same structures, elements or fittings appearing in more than two figures to reflect similar features.

[0018] An embodiment of the present application discloses a deep foundation pit slope support structure, including a sleeve shaft 1, a fixed seat 4 and two baffles 3. The top of the fixed seat 4 is installed with a threaded rod 2 through a bearing. The top of the threaded rod 2 is installed with a limit seat 201. The outer part of the threaded rod 2 is movably provided with a sleeve shaft 1. Both sides of the sleeve shaft 1 are installed with connecting rods 101 through rotating shafts. One end of the connecting rod 101 is installed with a force-bearing seat 5 through a rotating shaft. One side of the force-bearing seat 5 is fixedly installed with a baffle 3. The inside of the baffle 3 is installed with a reinforcing rib 301

[0019] The fixing seat 4 and the threaded rod 2 are installed through bearings, so that the threaded rod 2 can rotate when the fixing seat 4 is fixed, and the limit seat 201 can limit the moving position of the sleeve shaft 1. The connecting rod 101 can play a supporting role. The connecting rod 101 and the sleeve shaft 1 are movably connected by a rotating shaft. When the sleeve shaft 1 moves vertically, the angle of the connecting rod 101 will change, thereby adjusting the supporting force for the baffle 3. The supporting force of the connecting rod 101 will be transmitted to the baffle 3 through the force seat 5.

[0020] A ground plug 401 is installed at the bottom of the fixing seat 4, and fixing bolts are installed on both sides of the fixing seat 4. The fixing seat 4 can be installed on the ground inside the foundation pit through the cooperation of the ground plug 401 and the fixing bolts.

[0021] A turntable 202 is provided at the lower part of the outside of the threaded rod 2, and anti-slip grooves are provided on the outside of the turntable 202. The turntable 202 is convenient for the staff to rotate the threaded rod 2. The anti-slip grooves can increase the friction of the turntable 202. When the staff cannot rotate it manually, they can choose to use tools to clamp the turntable 202 for rotation.

[0022] A reflective strip 302 is installed outside the reinforcing rib 301 .

[0023] Fixing bolts are installed at both ends of the baffle 3.

[0024] The implementation principle of the embodiment of the present application is as follows: when in use, the two baffles 3 are installed on the vertical slope protection on both sides of the pit foundation and fixed. The baffles 3 are fixed to the wall on one side and to the ground on the other side. The reinforcing ribs 301 can form a stable triangle, which can reinforce the retaining wall and supporting structure in the pit foundation. The reinforcing ribs 301 are of a half-moon design, which can reduce the space occupied by the pit foundation by this structure, and at the same time can avoid the support structure from tripping over the workers to the greatest extent, thereby improving the safety of the device. Rotating the threaded rod 2 can make the sleeve shaft 1 move vertically, and the vertical movement of the sleeve shaft 1 can drive the connecting rod 101 to be linked, and the connecting rod 101 can move vertically. It is connected to the sleeve shaft 1 through a rotating shaft, and its angle can be changed. Through the coordinated use of the sleeve shaft 1 and the connecting rod 101, the supporting strength of the device can be adjusted, which can prevent the device from being deformed due to long-term use, thereby causing the supporting force of the device to decay, and can maintain the supporting property of the support structure, thereby improving the practicality of the device. Through the reflective strip 302, the conspicuousness of the support structure can be increased when the workers shuttle through the construction site at night, and the support structure can be prevented from being tripped by the workers because they fail to find the reinforcement structure due to the dim lighting at the construction site at night after the reinforcement structure is installed, thereby preventing the device from affecting the activities of the workers and improving the safety of the device.
