Description

Technical Field

[0001] This utility model relates to the technical field of wave pile installation, and in particular to a wave pile head limiting device for river channel restoration. Background Technology

[0002] Wave piles are a new type of prestressed concrete component widely used in water conservancy projects, river management, and bank protection reinforcement. Their cross-sections are typically semi-circular or arc-shaped, possessing high flexural strength, durability, and aesthetic appeal, making them suitable for various geological conditions and engineering requirements. In river construction, precast wave piles play a crucial role in riverbank and slope protection.

[0003] However, the traditional method of constructing wave piles involves manual correction of the verticality of the waves by workers, which results in large positioning deviations, affecting the stability of the riverbank and the progress of the project. Utility Model Content

[0017] To enable those skilled in the art to better understand the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings.

[0018] As described in the background section, the traditional method of constructing wave piles involves manual correction of the verticality of the waves by workers, which results in large positioning deviations, affecting the stability of the riverbank and the progress of the project.

[0019] To solve this technical problem, this utility model provides a limiting device for the first pile of a wave pile for river channel restoration, which is applied to the construction and installation of the first pile of a wave pile.

[0020] It should be noted that, unless otherwise specified, the embodiments and features and technical solutions in the present invention can be combined with each other.

[0021] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0022] Example 1

[0023] Please refer to Figure 1-3 A wave pile head positioning device for river channel restoration specifically includes: a wave pile body 1 and a positioning mechanism for straightening and installing the wave pile body 1. The positioning mechanism includes a positioning frame 2, multiple positioning cones 3 installed at the bottom of the positioning frame 2, and two abdominal support positioning rods 4 installed inside the positioning frame 2. The wave pile body 1 is provided with two arc-shaped concave portions 5 facing opposite directions. The edge of the wave pile body 1 is tangent to the inner wall of the positioning frame 2. The end of the abdominal support positioning rod 4 extends into the corresponding arc-shaped concave portion 5 and slides in contact with the inside of the arc-shaped concave portion 5.

[0024] For details, please refer to Figure 1 Both sides of the wave pile body 1 are provided with axially extending grooves 6, and the inner wall of the positioning frame 2 is provided with positioning blocks 7 that fit with the grooves 6; furthermore, the positioning blocks 7 can slide up and down along the grooves 6.

[0025] For details, please refer to Figure 2The end of the abdominal support positioning rod 4 is rotatably mounted with a first roller 8, and the end of the abdominal support positioning rod 4 slides in contact with the arc-shaped concave part 5 of the wave pile body 1 through the first roller 8; furthermore, the first roller 8 is used to reduce the friction between the abdominal support positioning rod 4 and the inner wall of the arc-shaped concave part 5 on the wave pile body 1.

[0026] The first pile limiting device for river channel restoration provided in this embodiment, under the action of the positioning block 7, allows the sliding groove 6 on the wave pile body 1 to slide vertically up and down along the positioning block 7, further improving the installation verticality of the wave pile body 1, and at the same time preventing the wave pile body 1 from rotating in the horizontal direction, so as to further improve the installation accuracy of the wave pile; under the action of the first roller 8, the frictional resistance of the bracing positioning rod 4 on the wave pile body 1 during the downward movement of the wave pile body 1 can be reduced, improving the smoothness of the downward movement of the wave pile body 1.

[0027] Example 2

[0028] The wave pile head limiting device for river channel restoration provided in Example 1 has been further optimized. For details, please refer to... Figure 1 and Figure 3 Multiple adjustment supports are installed around the bottom of the positioning frame 2. These supports are used for leveling the positioning frame 2 and for auxiliary support. Each adjustment support includes a slide rail 9 fixedly installed at the bottom of the positioning frame 2, two slide blocks 10 slidably installed on the slide rail 9, two scissor braces 11 hinged together at their midpoints, and a drive component 12 that provides power for the synchronous, opposite-direction sliding of the two slide blocks 10. The upper ends of the scissor braces 11 are hinged to the slide blocks 10. Furthermore, the drive component 12 is preferably a threaded screw, which contacts the two slide blocks 10. The threads at the points are reversed, and a rocker wheel is fixedly installed at the end of the threaded screw; the driving component 12 can be other equivalent components that can drive the two slide blocks 10 to slide synchronously in opposite directions; furthermore, there are at least two sets of adjusting supports. When there are two sets of adjusting supports, the two adjusting supports are symmetrically arranged on both sides of the bottom of the positioning frame 2; there can also be four sets of adjusting supports. When there are four sets of adjusting supports, the adjusting supports are evenly distributed around the bottom of the positioning frame 2; the scissor support 11 is composed of two support rods that are hinged to each other in the middle, and the two support rods are arranged in a cross shape.

[0029] For details, please refer to Figure 1 or Figure 3 Two second rollers 13 are rotatably mounted at both ends of the bottom of the scissor lift member 11; furthermore, the bottom ends of the scissor lift member 11 roll in contact with the ground through the second rollers 13.

[0030] For details, please refer to Figure 3 The bottom of the positioning cone 3 is at least 20cm lower than the bottom of the scissor brace 11 to ensure that the positioning cone 3 is inserted into the ground at least 20cm, thereby ensuring the installation stability of the first pile limiting device on the ground.

[0031] For details, please refer to Figure 1 or Figure 2 Bubble level 14 is installed on both sides of the top center of the positioning frame 2.

[0032] The first pile limiting device for river channel restoration wave piles provided in this embodiment can distribute the force at the positioning frame 2 by adjusting the support member, and provide upward support for the positioning frame 2 to reduce the load-bearing pressure on the positioning cone 3. This prevents the positioning frame 2 from moving down synchronously with the wave pile body 1 during the installation process. By activating the drive member 12, the two sliding blocks 10 are brought closer or further apart. After being driven by the scissor support member 11, the height of one side of the positioning frame 2 can be adjusted. Under the action of the adjusting support member, the positioning frame 2 can be adjusted to a horizontal state, and the bubble level 14... It can help operators determine whether the positioning frame 2 is in a horizontal state; after the wave pile is installed, the driving component 12 drives the two sliding blocks 10 to move closer to each other, and the two second rollers 13 at the bottom of the scissor support 11 move closer to each other and generate an upward force between them and the ground. The rotation of the second rollers 13 can greatly reduce the frictional resistance between the scissor support 11 and the ground, so that the positioning frame 2 can move upward smoothly, and the positioning cone 3 can be gradually pulled away from the ground, so that the operator can remove the first pile limiting device more easily, improve the convenience of removing the first pile limiting device, and shorten the removal time.

[0033] The usage process of the wave pile first pile limiting device for river channel restoration provided by this utility model is as follows: Mark the installation position of the first wave pile on the ground, move the first pile limiting device to the marked position, and hammer the positioning cone 3 into the soil with a hammer. Adjust the various adjustment supports so that the second roller 13 contacts the ground until the positioning frame 2 is in a horizontal state as observed by the bubble level 14. Insert the wave pile body 1 into the positioning frame 2 from the top of the positioning frame 2, with the outer wall of the wave pile body 1 tangent to the inner wall of the positioning frame 2. The belly support positioning rod 4 limits the arc-shaped concave part 5 of the wave pile body 1 through the first roller 8. Press the wave pile body 1 vertically into the ground below the ground with an external pile driver.
