Description

Technical Field

[0001] The invention belongs to the technical field of pile foundation protection, and in particular relates to a bridge pile foundation protection device for bridge construction. Background Art

[0002] Bridge pile foundation is an indispensable part of bridge construction. It bears the weight of the bridge and transfers the load to the foundation to ensure the stability and safety of the bridge. Bridge pile foundation protection refers to a series of measures taken to protect the pile foundation of the bridge from external environmental factors or other damage. Damage or corrosion to the bridge pile foundation will directly affect the stability and safety of the bridge.

[0013] The present invention has the following beneficial effects: 1. The present invention gradually moves downward by rotating the gravity pushing rod. The downward moving gravity pushing rod pushes the semicircular transmission seat downward and compresses each first elastic member. The lower pull rod that moves downward synchronously with the first elastic member drives the lower pushing part to move downward. After the lower pushing part contacts the connecting part, it drives the axial moving part to move downward along the axial groove. During the downward movement of the axial moving part, the oblique pushing part is driven to rotate. The oblique pushing part that rotates counterclockwise drives the radial locking part to move toward the bridge pile foundation. In this process, the radial limit plate moves along the radial groove. The second elastic member is stretched by the force until the threaded structure on the gravity pushing rod just leaves the outer extension seat. At this time, the gravity pressure-bearing part is close to the outer extension seat, and the inner surface of the radial locking part is close to the inner protective pad. When the gravity pressure-bearing part continues to be pressed down until it abuts against the top of the outer extension seat, the radial locking part continues to move radially under the thrust of the gravity pushing rod until it is tightly pressed against the inner protective pad. In this way, the inner protective pad is tightly attached to the bridge pile foundation through the circumferentially arranged radial locking parts. The combination of internal and external protection can greatly improve the protection effect of the bridge pile foundation.

[0014] 2. In the present invention, after an outer protective cover is sleeved and installed on the bridge pile foundation, another outer protective cover is aligned with the above outer protective cover so that the first positioning portion is aligned with the first positioning groove. Then, when both outer protective covers are sleeved and fitted on the bridge pile foundation, each first positioning portion is inserted into the corresponding first positioning groove to realize the clamping assembly of the two cushion layer installation components on the bridge pile foundation. Then, the inner protective pad is wound and installed between each cushion layer winding rod, thereby completing the sleeve installation of the inner protective mechanism on the bridge pile foundation. Then, the inner protective mechanism is inserted from the upper port of the outer protective cover into the inner part of the outer protective mechanism until the inner protective mechanism is The arc-shaped positioning seat at the bottom of the mechanism is plugged into the arc-shaped positioning groove, so that the inner protection mechanism is installed and fixed in the outer protection mechanism. During this process, the gravity pushing rod is gradually inserted into the first fixing hole on the outer protection cover. When the first mounting ring abuts against the top of the outer protection cover, the lower end of the gravity pushing rod passes through the first fixing hole on the semicircular bearing seat and abuts against the top of the semicircular transmission seat. In this way, the two gravity pushing rods on the inner protection mechanism are used to fix the two outer protection components that are clamped together, which can effectively avoid the problem of loosening of the bolt fixing method in the prior art due to long-term use, resulting in reduced stability.

[0037] In this embodiment of the present invention, the transmission assembly also includes an arc-shaped support seat 703, which is fixedly arranged on the inner wall of the outer protective cover 301, the semicircular transmission seat 701 is arranged below the semicircular bearing seat 302 and the lower pull rod 702 is slidably matched with the semicircular bearing seat 302, the arc-shaped support seat 703 is arranged below the semicircular transmission seat 701 and the two are connected by a first elastic member 704, and a push-down portion 705 is fixedly arranged on the top of the lower pull rod 702; the gravity locking assembly 8 also includes an axial moving portion 8 03, the axial moving part 803 is slidably connected with the corresponding axial groove 304, a connecting part 804 slidably sleeved on the corresponding lower pull rod 702 is fixedly arranged on one side of the axial moving part 803, a plurality of groups of ear seats 805 corresponding to the axial moving part 803 are fixedly arranged on the top of the semicircular bearing seat 302, a guide shaft 806 is fixedly arranged between each group of ear seats 805, a guide channel 807 is opened inside the oblique pushing part 801, and the guide shaft 806 is slidably fitted inside the guide channel 807; The side of the oblique pushing portion 801 away from the radial locking portion 802 is rotatably connected to the corresponding axial moving portion 803, and the side of the radial locking portion 802 close to the oblique pushing portion 801 is symmetrically fixed with two radial limit plates 808, and the radial limit plates 808 are slidably matched inside the corresponding radial groove 303. An arc-shaped fixing seat 809 is fixed on the inner wall of the outer protective cover 301, and the arc-shaped fixing seat 809 is connected to the corresponding radial locking portion 802 through a second elastic member 810; in the initial state The semicircular transmission seat 701 is supported by each first elastic member 704. At this time, the push-down portion 705 at the top of each pull-down rod 702 is located above the connecting portion 804, and the axial moving portion 803 abuts against the top of the corresponding axial groove 304. Under the action of the second elastic member 810, the radial locking portion 802 is fitted in the corresponding limit opening 305, and the radial limit plate 808 slides in the corresponding radial groove 303, and the semicircular transmission seat 701 just abuts against the bottom of each arc-shaped fixed seat 809.

[0038] After an outer protective cover 301 is sleeved and installed on the bridge pile foundation, another outer protective cover 301 is aligned with the above-mentioned outer protective cover 301, so that the first positioning portion 306 is aligned with the first positioning groove 307. Then, when the two outer protective covers 301 are sleeved and fitted on the bridge pile foundation, each first positioning portion 306 is inserted into the corresponding first positioning groove 307. Subsequently, the two cushion installation components 5 are snap-fitted and assembled on the bridge pile foundation through the same assembly method mentioned above, and then the inner protective pad 6 is wound and installed between each cushion winding rod 506.

During the downward movement of the axial moving portion 803, the oblique pushing portion 801 is driven to rotate (in this process, the guide shaft 806 slides along the guide channel 807), and the radial locking portion 802 is pushed toward the direction of the bridge pile foundation by the counterclockwise rotating oblique pushing portion 801. The second elastic member 810 is stretched by the force during the movement, until the threaded structure 502 on the gravity pushing rod 501 just breaks away from the outer extension seat 507, at which time the gravity pressure-bearing portion 503 is close to the outer extension seat 507 (there is a certain distance between the gravity pressure-bearing portion 503 and the outer extension seat 507), and the inner surface of the radial locking portion 802 is close to the inner protection pad 6. When the gravity pressure-bearing portion 503 is continuously pressed down until it abuts against the top of the outer extension seat 507, the radial locking portion 802 continues to move radially under the thrust of the gravity pushing rod 501 until it is tightly pressed against the inner protection pad 6, thereby achieving the inner protection pad 6 being tightly attached to the bridge pile foundation through the circumferentially arranged radial locking portions 802.This combination of internal and external protection can greatly improve the protection effect of bridge pile foundations.
