Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of reinforcement devices, and more specifically, particularly relates to a pile foundation reinforcement device. Background Technique
[0002] In the construction industry, the load-bearing of large highways, railways, and bridges depends on the pile foundations below them. If the entire pile body is buried in the soil and the bottom surface of the bearing platform contacts the soil, it is called a low-capacity pile foundation. Due to the influence of the natural geographical environment and the service life, the internal structure of the pile foundations of most existing bridges changes, and the stability decreases, posing a safety hazard to the entire project. Therefore, there is an urgent need to reinforce them through a reinforcement device.
[0003] The existing device needs to be reinforced by ground nails. After reinforcement, due to the weak bonding strength between the ground nails and the soil, the bearing capacity is reduced. After the existing device is used for a period of time, the reinforcement device will tilt following the tilt of the pile foundation, and at this time, it needs to be reinstalled, and the operation is cumbersome. Content of the Utility Model
[0004] In order to solve the above technical problems, the utility model provides a pile foundation reinforcement device to solve the problems that the existing device needs to be reinforced by ground nails, and after reinforcement, due to the weak bonding strength between the ground nails and the soil, the bearing capacity is reduced; after the existing device is used for a period of time, the reinforcement device will tilt following the tilt of the pile foundation, and at this time, it needs to be reinstalled, and the operation is cumbersome.
[0005] The purpose and effect of a pile foundation reinforcement device of the utility model are achieved by the following specific technical means:
[0006] A pile foundation reinforcement device includes a pile foundation; the pile foundation is fixed in the soil, and a connection component is installed on the pile foundation.
[0007] Further, the connection component is composed of a seat body, a fixing screw, a locking nut, and a limiting seat. Two seat bodies are clamped on the pile foundation, and the two seat bodies are fixed by two fixing screws and two locking nuts.
[0008] Further, two limiting seats are welded on the right seat body. Both limiting seats are concave structures, and the two limiting seats are clamped with the hexagonal blocks on the two fixing screws. At this time, the fixing screws are in a limited state.
[0009] Further, a support component is installed on the seat body. The support component is composed of a connection block, a threaded rod, a support seat, and an adjusting nut. A connection block is rotated on each seat body, a threaded rod is threadedly connected to each connection block, and a support seat is threadedly connected to the lower end of each threaded rod. The two support seats are fixed on the ground through a fixing component.
[0010] Further, the thread directions of the upper end and the lower end of the threaded rod are opposite, and an adjusting nut is welded to the middle part of the threaded rod.
[0011] Further, the fixing component is composed of ground nails, auxiliary plates and retaining rings. A ground nail is inserted into each support seat, and both ground nails are inserted into the soil.
[0012] Further, two auxiliary plates are welded to each ground nail. The two auxiliary plates are both in the shape of a right trapezoid, and the two auxiliary plates together form a structure for enhancing the stability of the ground nail.
[0013] Further, a retaining ring is welded to each ground nail. The bottom end faces of the two retaining rings are respectively in contact with the top end faces of the two support seats. Under the support of the two support seats, the stepped parts at the tops of the two ground nails are not in contact with the top end faces of the support seats.
[0014] Compared with the prior art, the utility model has the following beneficial effects:
[0015] In this application, through the arrangement of the support component, when the pile foundation is inclined, a wrench can be directly clamped on the adjusting nut and rotated. At this time, because the thread directions of the upper end and the lower end of the threaded rod are opposite, on the one hand, the pile foundation can be righted, and on the other hand, the adjustment efficiency is high.
[0016] In this application, through the arrangement of the fixing component, on the one hand, after the ground nail is inserted into the support seat, the auxiliary plate is synchronously inserted into the soil. At this time, the bonding strength between the ground nail and the soil can be improved through the two auxiliary plates, reducing the probability of the ground nail tilting under force; on the other hand, when disassembling the ground nail, a crowbar can be directly inserted into the stepped part between the support seat and the ground nail and pried, and the disassembly is convenient.
[0017] In this application, through the arrangement of the connecting component, when the seat body is tightened, a wrench can be directly clamped on the locking nut and tightened, and there is no need to use another wrench to limit the fixing screw. BRIEF DESCRIPTION OF THE DRAWINGS

[0032] Embodiment 1
[0033] As shown in the attached Figure 1 to the attached Figure 6 as follows:
[0034] The utility model provides a pile foundation reinforcement device, including a pile foundation 1; the pile foundation 1 is fixed in the soil, and a connection component 2 is installed on the pile foundation 1.
[0035] Among them, the connection component 2 is composed of a seat body 201, a fixing screw 202, a locking nut 203 and a limit seat 204. Two seat bodies 201 are clamped on the pile foundation 1, and the two seat bodies 201 are fixed by two fixing screws 202 and two locking nuts 203.
[0036] Among them, two limit seats 204 are welded on the right seat body 201. The two limit seats 204 are both concave structures. The two limit seats 204 are clamped with the hexagonal blocks on the two fixing screws 202. At this time, the fixing screw 202 is in a limited state. When fastening the seat body 201, directly use a wrench to clamp on the locking nut 203 and tighten it, without using another wrench to limit the fixing screw 202.
[0037] Among them, a support component 3 is installed on the seat body 201. The support component 3 is composed of a connection block 301, a threaded rod 302, a support seat 303 and an adjustment nut 304. A connection block 301 is rotated on each seat body 201, a threaded rod 302 is threadedly connected to each connection block 301, a support seat 303 is threadedly connected to the lower end of each threaded rod 302, and the two support seats 303 are both fixed on the ground through a fixing component 4.
[0038] Among them, the thread directions of the upper end and the lower end of the threaded rod 302 are opposite. An adjustment nut 304 is welded to the middle part of the threaded rod 302. When adjusting the length of the support component 3, use a wrench to clamp on the adjustment nut 304 and rotate it. At this time, because the thread directions of the upper end and the lower end of the threaded rod 302 are opposite, the adjustment efficiency can be improved.
[0039] Among them, the fixing component 4 is composed of a ground nail 401, an auxiliary plate 402 and a retaining ring 403. A ground nail 401 is inserted into each support seat 303, and the two ground nails 401 are both inserted into the soil.
[0040] Among them, two auxiliary plates 402 are welded on each ground nail 401. The two auxiliary plates 402 are both right-angled trapezoidal plate structures. The two auxiliary plates 402 together form a structure for enhancing the stability of the ground nail 401. After the ground nail 401 is inserted into the support seat 303, the auxiliary plates 402 are synchronously inserted into the soil. At this time, the bonding strength between the ground nail 401 and the soil can be improved through the two auxiliary plates 402, and the probability of the ground nail 401 being inclined under force is reduced.
[0041] Embodiment 2:
[0042] On the basis of Embodiment 1, a retaining ring 403 is welded to each ground nail 401. The bottom end surfaces of the two retaining rings 403 are respectively in contact with the top end surfaces of the two support seats 303. Supported by the two support seats 303, the stepped parts at the tops of the two ground nails 401 are not in contact with the top end surfaces of the support seats 303. When disassembling the ground nail 401, directly insert a crowbar into the stepped part between the support seat 303 and the ground nail 401 and pry it, and the disassembly is convenient.
[0043] Working principle: When fixing, snap the two seat bodies 201 onto the pile foundation 1 and lock them with two fixing screws 202 and two locking nuts 203; when the seat body 201 is tightened, directly use a wrench to snap onto the locking nut 203 and tighten it, without the need to use another wrench to limit the fixing screw 202; after the ground nail 401 is inserted into the support seat 303, then strike the ground nail 401 to drive the ground nail 401 into the soil, and at this time the auxiliary plate 402 is synchronously inserted into the soil; when the pile foundation 1 is tilted, at this time it is necessary to adjust the length of the support assembly 3. When adjusting the length of the support assembly 3, use a wrench to snap onto the adjusting nut 304 and rotate it.
