Description

Technical Field

[0001] This invention relates to the field of reinforcement equipment technology, specifically a grouting reinforcement device for bridge foundation piles. Background Technology

[0002] Foundation pit engineering is a crucial aspect of infrastructure construction, especially in bridge pile foundation construction. To ensure the stability and bearing capacity of the piles, grouting reinforcement of the surrounding soil is often necessary. Grouting technology fills soil pores and binds loose particles by injecting grout, thereby improving the physical and mechanical properties of the soil and increasing the lateral resistance and end bearing capacity of the piles. As bridge engineering develops towards longer spans, deeper water, and more complex geological conditions, higher demands are placed on the reliability, construction efficiency, and economy of pile reinforcement.

[0003] Traditional grouting reinforcement processes rely heavily on manual experience, leading to problems such as imprecise control of grouting pressure and uneven grout diffusion, resulting in highly inconsistent reinforcement effects. Furthermore, existing reinforcement devices lack flexibility in adapting to different pile diameters, depths, and inclination angles, often requiring multiple people to adjust the equipment's posture, increasing construction difficulty and labor costs. Some devices also have weak structural designs, with stress-concentrated components prone to fatigue damage, requiring frequent maintenance, impacting project progress, and driving up total life-cycle costs.

[0023] Please see Figures 1-4 In this embodiment of the invention, a grouting reinforcement device for bridge foundation piles includes a base plate 1 for bottom laying and a side protection mechanism 2 for pile reinforcement. The base plate 1 and the side protection mechanism 2 are supported by a support mechanism 3. The base plate 1, the side protection mechanism 2, and the support mechanism 3 constitute a reinforcement structure for pile reinforcement, enabling reinforcement of piles at different depths and angles.

[0024] The side guard mechanism 2 consists of a side plate 21, an extension plate 22, and a limiting component 23. The extension plate 22 is slidably connected to the side plate 21, and the limiting component 23 is disposed on the extension plate 22.

[0025] The support mechanism 3 consists of a slide rail 31, a pull rod 32, and a locking assembly 33. Each slide rail 31 has two components, and the locking assembly 33 is located between the two slide rails 31. The support mechanism 3 provides auxiliary support after the side guard mechanism 2 has been adjusted in angle.

[0026] The limiting component 23 includes a through groove formed on the extension plate 22. Holes are formed on both sides of the shell wall of the through groove, and an adjusting rod 231 is movably connected in the holes. The two ends of the adjusting rod 231 are respectively equipped with a plug-in member 232 for insertion and limiting and a force-bearing wedge 233 for compression adjustment.

[0027] Multiple force-bearing wedges 233 are slidably connected to a force-applying wedge 234 for drive adjustment. A threaded rod 235 is rotatably connected to the side wall of the force-applying wedge 234 via a bearing. A T-shaped groove is formed on the inclined surface of the force-bearing wedge 233, and a T-shaped slide bar is integrally formed on the inclined surface of the force-applying wedge 234. The T-shaped slide bar and the T-shaped groove are slidably connected. Both the force-bearing wedges 233 and the force-applying wedges 234 are slidably connected to the inner wall of the through groove, ensuring the stability of their displacement.

[0028] A groove is formed on the left side shell wall of the base plate 1, and the side plate 21 is connected to the groove by a pin. A receiving cavity is formed on the side plate 21, and the extension plate 22 is slidably connected to the receiving cavity. The sliding arrangement of the extension plate 22 in the receiving cavity allows for stable lifting and lowering adjustment during adjustment.

[0029] The front and rear side walls of the receiving cavity are provided with through slots, and multiple limiting slots for insertion and positioning are linearly distributed on the sides of the through slots. The outer ends of multiple adjusting rods 231 pass through the corresponding through slots. The insertion component 232 includes a connecting plate fixedly connected to the outer end of the adjusting rod 231. An insertion block for insertion and positioning is integrally provided on the side wall of the connecting plate. The insertion block in the insertion component 232 is inserted and positioned with the limiting slot to ensure that the extension plate 22 is locked after adjustment.

[0030] Above the through slot are a handrail and an L-shaped plate located on the outer wall of the extension plate 22. The handrail is located above the L-shaped plate, which has a threaded hole. The threaded rod 235, with one end away from the force-applying wedge 234, passes through the threaded hole and is equipped with an adjustment handle. The threaded rod 235 adjusts the displacement of the force-applying wedge 234 through the threaded hole on the L-shaped plate.

[0031] Two slide rails 31 are symmetrically arranged on the top of the base plate 1, and sliders are slidably connected to the slide rails 31. Each pull rod 32 has a support at both ends connected by a movable pin; the upper support is fixedly connected to the corresponding side wall of the side plate 21, and the lower support is respectively set on the corresponding slider. The pull rod 32 adjusts the angle of the side guard mechanism 2 as the slider moves. Multiple slots for limit locking are linearly distributed on the slide rails 31.

[0032] The locking assembly 33 includes a crossbeam 331 with multiple guide slots. A guide block is slidably connected in the guide slot, and a limiting rod 333 for locking and limiting is provided at the bottom of the guide block. The limiting rod 333 is inserted into the slot for limiting and fixing, thereby achieving the limiting and fixing of the support mechanism 3.

[0033] A handle and a support base are provided on the top outer wall of the crossbar 331. The support base is located between multiple guide slots. A bidirectional lead screw 332 for driving adjustment is movably connected to the support base, and multiple fixing plates are sleeved on the bidirectional lead screw 332. The bottom ends of the multiple fixing plates pass through the corresponding guide slots and are fixedly connected to the corresponding guide blocks. By adjusting the bidirectional lead screw 332, the multiple fixing plates on it are driven to move accordingly, thereby realizing the displacement adjustment of the corresponding guide blocks.

[0034] The working principle of this invention is as follows: Before operation, the following preparatory work must be completed: Pit cleaning and leveling: Clean and level the bottom of the pit on the side of the working pile to provide a stable foundation for the base plate 1. Place the entire device (base plate 1, side protection mechanism 2, support mechanism 3) at the predetermined position on the side of the pile, ensuring that the base plate 1 is in contact with the bottom of the pit, and the inner side of the side plate 21 is initially aligned with the outer wall of the pile. When the product is used, the height of the side protection mechanism 2 placed at the bottom of the pit is adjusted according to the depth of the pile. During the adjustment process, the threaded rod 235 in the limiting component 23 is adjusted first. The operator rotates the adjusting handle on the outside of the extension plate 22 to rotate the threaded rod 235. Because the threaded rod 235 engages with the threaded hole on the L-shaped plate, its rotation is converted into linear motion of the force-applying wedge 234 within the through groove, causing the force-applying wedge 234 to displace. The displacement adjustment of the force-applying wedge 234 drives the corresponding force-receiving wedge 233 to displace as well. The inclined surface of the force-applying wedge 234 fits against the inclined surfaces of the two force-receiving wedges 233. When the force-applying wedge moves, its inclined surface presses against the two force-receiving wedges, causing them to move simultaneously in a direction away from each other. The lateral displacement of the force-receiving wedge is converted into precise radial motion via the adjusting rod 231, pulling the connector 232 away from the limiting groove beside the through groove of the side plate 21, thereby releasing the locking of the extension plate. After the force-receiving wedge 233 displaces, the corresponding adjusting rod 231 moves, thereby causing the connector 232 on it to release the insertion limit between itself and the corresponding limiting groove. Then, the height of the extension plate 22 is adjusted using the handrail to reinforce the sidewall of the pit. After adjustment, the threaded rod 235 in the reverse adjustment limit assembly 23 is used to reverse the displacement of the force-applying wedge 234, driving the force-bearing wedge 233 again. The adjusting rod 231 then drives the corresponding connector 232 to insert into the corresponding limit groove, achieving limit fixation. After height adjustment, the adjusting handle is rotated in the reverse direction, causing the threaded rod 235 to move the force-applying wedge 234 inward. The pressure between the inclined planes is released, and the force-bearing wedge is reset under the assistance of spring force or gravity (or through precision fitting). The adjusting rod 231 pushes the connector 232 into the limit groove corresponding to the current position, achieving a stable mechanical pin lock and ensuring that the extension plate does not settle or loosen during subsequent reinforcement work.

[0035] When the angle of the side guard mechanism 2 needs to be adjusted, the locking component 33 in the support mechanism 3 is first adjusted to open its limit. The displacement of the sliding adjustment slider on the slide rail 31 is adjusted by the action of the pull rod 32 to achieve the adjustment of the support mechanism 3, thereby adjusting the angle of the side guard mechanism 2.

[0036] After the adjustment is completed, the bidirectional lead screw 332 in the locking assembly 33 is adjusted, which in turn drives the fixed plate sleeved with it to move the corresponding guide block, so that the limit rod 333 is inserted into the slot opened on the slide rail 31 to complete the limit locking, ensuring the limit of the side protection mechanism 2 after the angle is adjusted, and realizing the reinforcement of the foundation pile.

[0037] The above description is merely a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
