Description

Technical Field

[0001] This utility model relates to the field of bridge construction technology, and in particular to an underwater concrete pouring device. Background Technology

[0002] In the construction of underwater bridge pile foundations, it is necessary to first perform preliminary positioning of the pile foundation's planar position, and then use a total station to accurately lay out the center of the steel pipe. After meeting the design and specification requirements, the pilot hole is started. The pilot hole is drilled by a rotary drilling rig to create a grouting hole on the underwater surface. After the pilot hole is completed, the steel pipe is placed in the grouting hole. After placement, concrete is poured into the steel pipe. During the placement process, the planar position and elevation of the top of the steel pipe need to be measured and checked to ensure the accuracy of the steel pipe pile and to ensure that the steel pipe does not deviate due to water flow factors. Since the diameter of the steel pipe is smaller than the diameter of the grouting hole, and the steel pipe is lifted and transported by crane, the steel pipe is prone to swaying during placement, requiring multiple positioning, which greatly affects the construction progress. Utility Model Content

[0003] In view of the technical problems existing in the background art, the purpose of this utility model is to provide an underwater concrete pouring device that facilitates the positioning of steel pipes and makes underwater concrete pouring more efficient and faster.

[0005] An underwater concrete pouring device includes a steel pipe, a limiting component, and several sets of positioning components connected to the steel pipe. The positioning components are disposed on one side of the steel pipe and include positioning posts and several positioning clamps. The positioning clamps are connected to the outer wall of the steel pipe, and the positioning posts are disposed between adjacent positioning clamps. The positioning posts and the steel pipe are perpendicular to each other, and the positioning posts and positioning clamps are slidably connected. The limiting component is disposed at the upper end of the positioning components and connects the several sets of positioning components. The steel pipe is inserted into the pouring hole, and the positioning posts are connected to the outside of the pouring hole. Concrete is poured into the steel pipe.

[0006] Preferably, a positioning ring is also included, which is disposed on the outside of the steel pipe and is concentrically arranged with the injection hole.

Obviously, the described embodiments are some embodiments of this utility model, but not all embodiments.

[0021] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0022] Example

[0023] like Figures 1-4 As shown, an underwater concrete pouring device includes a steel pipe 2, a limiting component B, a positioning ring 4, and several sets of positioning components A connected to the steel pipe 2. The positioning components A are located on one side of the steel pipe 2. The positioning components A include positioning posts 6 and several positioning clamps 5. The positioning clamps 5 are welded to the outer wall of the steel pipe 2. The positioning clamps 5 in a set of positioning components A are arranged parallel to each other. The positioning posts 6 are located between adjacent positioning clamps 5. The positioning posts 6 and the steel pipe 2 are arranged perpendicular to each other. The positioning clamps 5 are provided with sliding grooves 51. The two sides of the positioning posts 6 are provided with protrusions 61. The protrusions 61 are slidably arranged in the sliding grooves 51. The positioning posts 6 and the positioning clamps 5 are slidably connected. One end of the positioning posts 6 is fitted with the steel pipe 2, that is, one end of the positioning posts 6 has an arc surface that fits with the outer wall of the steel pipe 2. When the positioning post 6 slides on the outside of the steel pipe 2, the positioning post 6 will not rotate. The positioning post 6 adopts a hollow structure, which can greatly reduce the weight of the overall structure and facilitate disassembly and assembly. When assembling the positioning component A, the position of the positioning clamp 5 is designed according to the depth of the grouting hole 1. After welding two adjacent positioning clamps 5 to the wall of the steel pipe 2, the positioning post 6 is placed between the adjacent positioning clamps 5. Protrusions 61 are welded on both sides of the positioning post 6 and the protrusions 61 are placed in the sliding groove 51. At this time, the positioning post 6 can slide on the outer wall of the steel pipe 2. Multiple positioning components A are set on the outer wall of the steel pipe 2 in this way, and multiple positioning components A are set in parallel. The steel pipe 2 and the positioning post 6 are connected by a sliding connection. The positioning post 6 is fixed to the ground. During the concrete pouring process, the steel pipe 2 cannot be connected to the bottom of the grouting hole 1. During the concrete pouring process, the steel pipe 2 needs to continuously extend out of the grouting hole 1 so that the concrete leaks from the bottom of the steel pipe 2 into the grouting hole 1, avoiding the accumulation of concrete in the steel pipe 2.

[0024] like Figure 1 , Figure 2As shown, the positioning ring 4 is set on the outside of the steel pipe 2. When installing the positioning component A, the positioning ring 4 is first placed on the outside of the grouting hole 1 using a total station, so that the positioning ring 4 and the grouting hole 1 are concentric. After the position of the positioning ring 4 is determined, the positioning ring 4 is snapped into the ground. The diameter of the positioning ring 4 is larger than the diameter of the grouting hole 1. One end of the positioning column 6 abuts against the positioning ring 4. The purpose of the positioning ring 4 is to position the steel pipe 2. When several positioning columns 6 abut against the position of the positioning ring 4 at the same time, the steel pipe 2 and the grouting hole 1 are concentric. The positioning columns 6 are connected to the ground by pressing. The mass of the pressing object is greater than the mass of the steel pipe 2, such as the I-beam 3. The pressing method not only greatly reduces the difficulty of installation, but also makes it easy to disassemble the positioning component A after grouting.

[0025] like Figures 1-4 As shown, the limiting component B is located on the upper end of the positioning component A and connects several sets of positioning components A. The limiting component B includes a limiting plate 7, which is located on the upper end of the positioning clamping plate 5. The two sides of the limiting plate 7 are respectively attached to the adjacent positioning posts 6. One end of the limiting plate 7 is provided with several limiting blocks 71, which are located between adjacent positioning components A. A protrusion 61 extends from the slide groove 51, and the limiting block 71 is connected to the lower end of the protrusion 61. The limiting component B is C-shaped. When the limiting plate 7 and the positioning clamping plate 5 are attached, the limiting block 71 and the protrusion 61 abut against each other, so that the protrusion 61 is located at the uppermost end of the slide groove 51. The limiting component B makes the adjacent positioning posts 6 parallel. The limiting component B and the positioning component A are detachably connected and connected by a plug-in method. The ground outside the injection hole 1 is uneven, and the positioning posts 6 are not parallel to each other during installation. When the I-beam 3 is pressed on top of the positioning posts 6, it is easy to generate large stress on the positioning posts 6, causing the steel pipe 2 to twist. After setting the limiting component B, when installing the steel pipe 2, the limiting component B keeps each positioning post 6 in a parallel position. When installing the steel pipe 2, the installation position can be observed by checking the parallel state of the positioning posts 6 and the ground. If there is a large undulation between the positioning posts 6 and the ground, the ground debris should be cleared or the installation position changed to make the positioning posts 6 parallel to the ground. At this time, the I-beam 3 can be pressed onto the upper end of the positioning post 6, which can greatly increase the installation accuracy and avoid the steel pipe 2 and positioning posts 6 from twisting during the installation process, thus preventing damage to the positioning component A.

[0026] Working principle: After the injection hole 1 is set, a positioning ring 4 is installed on the outside of the injection hole 1. The positioning clamp 5 is welded to the steel pipe 2. Protrusions 61 are welded on both sides of the positioning column 6, allowing the positioning column 6 to slide within the positioning clamp 5. Pulling the positioning column 6 causes the protrusions 61 to slide to the upper end of the slide groove 51. The limiting plate 7 is connected to the upper end of the positioning clamp 5, so that the limiting block 71 abuts against the lower end of the protrusion 61, connecting the positioning component A and the limiting component B. At this time, the positioning column 6 is at the upper end of the positioning clamp 5. Place the positioning column 6 on the ground. Align the positioning post 6 and positioning ring 4, select a suitable installation position based on the parallelism between the positioning post 6 and the ground, press the I-beam 3 onto the upper end of the positioning post 6, and remove the limiting component B after pressing. At this time, the steel pipe 2 and the grouting hole 1 are concentric. Pour concrete into the steel pipe 2. The concrete leaks from the bottom of the steel pipe 2 into the grouting hole 1. As the concrete is continuously poured, the concrete at the bottom of the steel pipe 2 continuously lifts the steel pipe 2, causing the steel pipe 2 to slide towards the upper end of the grouting hole 1, preventing the concrete from blocking the steel pipe 2, making the underwater concrete pouring more efficient and faster.

[0027] This is merely a preferred embodiment of the present invention and is not intended to limit the present invention. For those skilled in the art, the present invention can have various modifications and variations. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
