Description

Technical Field

[0001] This utility model relates to the field of foundation pit engineering support technology, and more specifically, to a support device for anchor bolts in deep foundation pit soil layers. Background Technology

[0002] Foundation pit support technology is a complex and crucial branch of geotechnical engineering. Its core objective is to ensure the safety and stability of the foundation pit itself and its surrounding environment (adjacent buildings, roads, pipelines, etc.) during foundation pit excavation and underground structure construction. Support devices using soil anchors for deep foundation pits are mainly used in deep foundation pit projects. Through anchors, the load on the sidewalls of the foundation pit is transferred to the deep, stable soil layer, thereby maintaining the stability of the foundation pit slope.

[0003] For existing deep foundation pit soil anchor support devices, if multiple scattered support devices can be quickly connected into a whole, the load can be evenly distributed, stress concentration can be avoided, they can work together to improve overall rigidity, and foundation pit deformation can be effectively controlled to protect the surrounding environment. Utility Model Content

[0004] The purpose of this utility model is to provide a support device for anchor bolts in deep foundation pits, so as to solve the problem of inconvenient connection of multiple scattered devices in the existing support devices for anchor bolts in deep foundation pits mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides a support device for anchor bolts in deep foundation pits, which is achieved through the following specific technical means: A support device for anchor bolts in deep foundation pits includes: a first support rod, a second support rod, a fixing sleeve, a limiting block, a first vertical plate, a second vertical plate, a horizontal plate, a locking block, a connecting plate, a screw, and a nut; two first support rods are provided, and a second support rod is inserted into the inner wall of each first support rod; a first vertical plate is fixedly connected to the outer wall of each of the two first vertical plates; a second vertical plate is attached to the outer wall of each of the two first vertical plates, and the inner wall of each of the two second vertical plates is attached to the outer wall of each of the two first support rods; a horizontal plate is fixedly connected to the upper and lower sides of one side of the outer wall of each of the two second vertical plates; a locking block is fixedly connected to the outer wall of each of the multiple horizontal plates; a connecting plate is locked to the outer wall of some of the locking blocks, and the outer wall of each of the two connecting plates is attached to the outer wall of a portion of the horizontal plate; a screw is inserted into the inner wall of each of the two connecting plates; nuts are threaded to both ends of the outer wall of each screw, and the outer walls of the two nuts abut against the outer walls of the two connecting plates.

[0006] As a further optimization of this technical solution, in the support device for anchor rods in deep foundation pits of this utility model, one end of each of the two second support rods is fixedly connected to a fixing sleeve, and the inner wall of the two fixing sleeves respectively fits into one end of the outer wall of the two first support rods.

[0007] As a further optimization of this technical solution, the inner walls of the two fixing sleeves, the two first vertical plates and the two second vertical plates of the support device for anchor bolts in deep foundation pits of this utility model are all machined with threaded holes.

[0008] As a further optimization of this technical solution, the support device for anchor rods in deep foundation pits of this utility model has multiple limiting blocks inserted into the inner walls of the two first support rods.

[0009] As a further optimization of this technical solution, in the support device for anchor bolts in deep foundation pits of this utility model, one side of each of the limiting blocks has an inclined structure.

[0010] Due to the application of the above technical solution, this utility model has the following advantages compared with the prior art: 1. The arrangement of the first support rod, first vertical plate, second vertical plate, horizontal plate, clamping block, connecting plate, screw rod, and nut in this utility model can connect the scattered support devices into a whole, thereby evenly distributing the load, avoiding stress concentration, and greatly improving the safety redundancy of the system. At the same time, the entire support structure becomes a continuous and rigid integral wall structure. The bending and shear stiffness of this whole is much greater than the simple sum of the stiffness of all the independent piles, which can more effectively resist the deformation caused by soil pressure. The integral system has high stiffness and extremely strong deformation control capability. It can control the lateral displacement of the foundation pit within a very small range, thereby minimizing the disturbance to the surrounding environment.

[0011] 2. This utility model improves the support device for anchor bolts in deep foundation pits, which can connect multiple scattered support devices into a whole, distribute the load evenly, avoid stress concentration, work together to improve overall rigidity, and effectively control the deformation of the foundation pit and protect the surrounding environment. Thus, it effectively solves the problems and shortcomings of existing devices. Attached Figure Description

Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0018] Please see Figures 1 to 4 This utility model provides a specific technical implementation scheme for a support device for anchor bolts in deep foundation pits: A support device for anchor bolts in deep foundation pits includes: a first support rod 1, a second support rod 2, a fixing sleeve 3, a limiting block 4, a first vertical plate 5, a second vertical plate 6, a horizontal plate 7, a locking block 8, a connecting plate 9, a screw rod 10, and a nut 11; two first support rods 1 are provided, and a second support rod 2 is inserted into the inner wall of each of the two first support rods 1; a first vertical plate 5 is fixedly connected to the outer wall of each of the two first vertical plates 5; a second vertical plate 6 is attached to the outer wall of each of the two first vertical plates 5, and the inner wall of each of the two second vertical plates 6 is respectively attached to the outer wall of each of the two first support rods 1; a horizontal plate 7 is fixedly connected to the upper and lower sides of one side of the outer wall of each of the two second vertical plates 6; and the outer walls of multiple horizontal plates 7 are fixedly connected to... There are locking blocks 8, and the outer walls of some locking blocks 8 are locked with connecting plates 9. The outer walls of two connecting plates 9 are respectively attached to the outer walls of some horizontal plates 7. The inner walls of the two connecting plates 9 are inserted with screws 10. The outer ends of the outer walls of the screws 10 are threaded with nuts 11, and the outer walls of the two nuts 11 are respectively abutted against the outer walls of the two connecting plates 9. When connecting, the operator can use an appropriate number of connecting plates 9, screws 10 and nuts 11 to connect multiple second vertical plates 6 to realize the connection work of the device. The locking blocks 8 can lock and limit the connecting plates 9 to ensure the stability of the connecting plates 9.

[0019] Each of the two second support rods 2 has a fixed sleeve 3 fixedly connected to one end, and the inner wall of the two fixed sleeves 3 respectively fits into one end of the outer wall of the two first support rods 1; the fixed sleeve 3 can be fitted onto the outer wall of the first support rod 1 when the second support rod 2 is fully inserted into the inner wall of the first support rod 1, thereby isolating and protecting the connection between the first support rod 1 and the second support rod 2.

[0020] The inner walls of the two fixing sleeves 3, the two first vertical plates 5, and the two second vertical plates 6 are all machined with threaded holes; the workers can connect and fix the fixing sleeves 3, the first vertical plates 5, and the second vertical plates 6 with bolts, so that when the second support rod 2 is fully inserted into the inner wall of the first support rod 1, the second support rod 2 and the first support rod 1 can be fixed and limited.

[0021] Multiple limiting blocks 4 are inserted into the inner walls of both first support rods 1; the limiting blocks 4 can increase the movement resistance between the first support rod 1 and the soil layer when the first support rod 1 is inserted into the soil layer, so as to improve the insertion stability.

[0022] One side of each of the multiple limiting blocks 4 has an inclined structure; the inclined design allows the limiting blocks 4 to be pushed out better when the second support rod 2 is pushed to move along the inner wall of the first support rod 1.

[0023] Specifically, the distance between the two first support rods 1 can be determined based on specific factors such as soil properties, pit depth, surrounding environment, and construction feasibility. Correspondingly, a suitable length of screw rod 10 needs to be selected for better connection and use. Those skilled in the art should understand this in a broad sense.

[0024] Specific implementation steps

[0025] During use, the workers first drill installation holes inside the foundation pit using an external drilling rig or other equipment. Then, the first support rod 1 is inserted into the installation hole, and the fixing sleeve 3 is pushed, which in turn drives the second support rod 2 to insert into the inner wall of the first support rod 1. At this time, the limiting block 4 moves along the inner wall of the first support rod 1. When the second support rod 2 is fully inserted into the inner wall of the first support rod 1, the fixing sleeve 3, the first vertical plate 5, and the second vertical plate 6 are then connected and fixed using external bolts. Then, the connecting plate 9 is snapped onto the outer wall of the clamping block 8, and the screw 10 is inserted into the inner wall of the two connecting plates 9. Finally, the connection and fixation are achieved through the cooperation of the nut 11 and the screw 10, and the assembly work is completed.

[0026] In summary, this support device for deep foundation pit soil anchors, through the arrangement of a first support rod, a first vertical plate, a second vertical plate, a horizontal plate, a locking block, a connecting plate, a screw rod, and a nut, can connect scattered support devices into a whole, thereby evenly distributing the load, avoiding stress concentration, and greatly improving the system's safety redundancy. Simultaneously, the entire support structure becomes a continuous, rigid, integral wall structure. The bending and shear stiffness of this whole is far greater than the simple sum of the stiffness of all individual piles, enabling it to more effectively resist deformation caused by earth pressure. The overall system has high stiffness and extremely strong deformation control capability, controlling the lateral displacement of the foundation pit within a very small range, thus minimizing disturbance to the surrounding environment. This utility model, through improvements to the support device for deep foundation pit soil anchors, has the advantages of connecting multiple scattered support devices into a whole, evenly distributing the load, avoiding stress concentration, enabling collaborative work, improving overall stiffness, and effectively controlling foundation pit deformation, thus ensuring the safety of the surrounding environment. Therefore, it effectively solves the problems and shortcomings of existing devices.

[0027] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
