Description

Technical Field

[0001] The utility model relates to the field of construction platforms, and specifically to the technical field of an assembled pile foundation construction platform. Background Art

[0002] In the construction of pile foundations, it is crucial to ensure construction efficiency and precision. Most traditional pile foundation operation platforms rely on on-site construction. This method not only takes a long time and requires a lot of effort, but also has weak functionality, affecting construction quality and safety. And usually, it needs to be customized and built according to the specific project requirements. This process involves a large amount of manual labor and on-site material allocation, which is not only costly, but also greatly restricted by weather conditions and prone to project delays.

[0003] In actual operation, a series of processes such as the positioning and lowering of the pile foundation casing, the protection during the punching (drilling) process, the remeasurement and positioning, the lowering of steel bars, the cleaning of the bottom of the hole, and the pouring of concrete all need to be completed on the platform, which poses extremely high requirements for the stability and versatility of the platform. Especially in the remeasurement and positioning link, ensuring accuracy is crucial for the safety and stability of the entire pile foundation structure, while traditional temporarily built platforms often have difficulty providing continuous and stable support and precise positioning auxiliary facilities.

[0004] Regarding this problem, for example, Chinese Patent CN202122895860.4 discloses a multi-functional operation platform for the construction of highway bridge pile foundations, which uses a scheme of building an operation platform through multiple symmetrically arranged vertical support steels and horizontal support steels, as well as longitudinal support steels between the horizontal support steels. However, the functional expansion of such a scheme is limited. It mainly solves the problem of the stability of concrete pouring, and only alleviates the quality hidden dangers brought by the terrain, and also needs to be built on-site.

[0005] In view of the above problems, there is an increasingly urgent need in the prior art for a pile foundation platform that can adapt to various construction conditions, is easy to assemble, and can efficiently support the full process of operation. Summary of the Utility Model

[0029] The features of the present utility model and other related features are further described in detail through the following embodiments for the understanding of those skilled in the same industry:

[0030] Please refer to Figure 1 , an assembled pile foundation construction platform in this case includes a casing 100 and a positioning panel 200 vertically and fixedly connected to the top of the casing 100. The casing 100 can be customized according to the size of the pile foundation, which is 10 - 15 cm larger than the diameter of the pile foundation. Please refer to Figure 4 for the preferred case. In order to facilitate hoisting, lifting rings 110 are arranged at the top opening position. Specifically, 4 lifting rings 110 are evenly arranged at its circular top opening, and U - shaped 16 - round steel can be welded to the top of the casing 100 for hoisting the platform.

[0031] Please refer to Figure 3 , the side wall of the casing 100 is provided with a mud drainage hole 120, and the mud can be drained out through the mud drainage hole 120. Specifically, referring to Figure 9 , a mud drainage port 120 with a diameter of 20 cm can be set at 30 cm below the lower edge of the top of the casing 100. The mud drainage port 120 can be welded with a funnel - shaped outlet to facilitate connecting the mud drainage pipe 121 and accessing the mud pit 122. This method can effectively solve the impact of mud on the surrounding environment during pile foundation construction, ensure that there is no silt around, and strengthen the on - site safety and civilized construction. The mud drainage port 120 can be customized according to the size of the pile foundation and the pouring rate. For the mud drainage pipe 121, it can be selected according to the terrain conditions and economic conditions, and plastic pipes or cloth - bag pipes can be used.

[0032] For the sizing panel 200, please refer to Figure 1 and Figure 4, the shaping panel 200 is a square panel, and a hollow portion 210 corresponding to the casing 100 is provided in the middle. During operation, the casing 100 is operated through the hollow portion 210. Therefore, the hollow portion 210 can at least cover the casing 100. In this way, the casing 100 and the shaping panel 200 are vertically fixedly connected, and the hollow portion 210 corresponding to the casing 100 is provided in the middle of the shaping panel 200, so that the working platform and the casing 100 can be assembled, which makes it convenient to disassemble and assemble on site and also convenient for transportation. Specifically, the shaping panel 200 can use 50 square steel as the main keel, 30 square steel as the secondary keel, and the top is fully covered with steel mesh.

[0033] At this time, the top of the shaped panel 200 is the work surface, so safety measures are needed. An outer shaped guardrail 220 is arranged on the periphery of the shaped panel 200, and the outer shaped guardrail 220 includes an outer positioning upright 221 respectively arranged at the corners of the shaped panel 200, that is, it is arranged at the four corners of the square panel. In addition, the outer shaped guardrail 220 also includes a protective railing 222 of not less than 1.5m on the outside, a pull plate of not less than 1.2m on the inside, and a skirting board 20cm below. The pull plate is a device widely used in industrial fields such as the construction industry and the manufacturing industry. In simple terms, the pull plate is a rectangular iron plate, which is usually used in the fields of renewable resource utilization, shipbuilding, railway and bridge construction, and construction. The surface of the guardrail should be painted with red and white interval warning paint. The guardrails are bolted together, and the inner and outer guardrails can be rotated and opened to facilitate workers to go up and down. The external positioning pole 221 plays the same role as the guardrail 222 in protection, and also belongs to the guardrail 222. In order to describe its role as a fixed point in the re-survey process, it is named differently. In this way, the external positioning pole 221 is used as a fixed point, and the four-point cross line method can be used to confirm whether the pile foundation construction is offset during the re-survey process.

[0034] Similarly, please combine Figure 2 , an inner shaped guardrail 230 is provided on the outer periphery of the hollow portion 210. In a preferred embodiment, the hollow portion 210 is also a square hollow, and the inner shaped guardrail 230 includes an inner positioning rod 231 provided at the inner corner of the hollow portion 210, and the inner positioning rod 231 can also be used as a fixed point for re-measurement. The design of other guardrail configurations is consistent with the outer shaped guardrail 220, and will not be repeated here.

[0035] The four-point crosshair method, also known as the four-point positioning method, is a technique for image correction or geometric rectification. This method is mainly used to determine the geometric deformation in an image. By precisely selecting four control points on the image and knowing their accurate positions in the actual space coordinate system, the geometric transformation parameters of the image are calculated, thereby achieving precise correction of the entire image. In this embodiment, the outer positioning vertical rod 221 and the inner positioning vertical rod 231 are fixed points and are used as the control points as described above.

[0036] The following details the vertical fixing method of the casing 100 and the shaping panel 200. Please refer to Figure 4 and Figures 6 to 8 , there is an inclined support 300 for supporting the shaping panel 200 between the outer periphery of the casing 100 and the outer periphery of the bottom of the shaping panel 200. Its arrangement direction can be set towards the four corners in view of the square characteristics of the shaping panel 200. At the same time, a chute 130 for installing the inclined support 300 is provided on the casing 100, which facilitates the disassembly and assembly of the inclined support.

[0037] The inclined support 300 is specifically made of channel steel and serves as the main load-bearing member of the platform. The lower end is obliquely cut and welded with steel plates that are slightly larger on each side, and the protruding part can be inserted into the chute 130 for matching use. The upper end is welded with a horizontal steel plate 310 and is bolted to the shaping panel 200, which is convenient for disassembly and installation.

[0038] The chute 130 is formed by welding an L30*30 angle steel on the side wall of the casing 100, and a section of steel bar is welded at the bottom of the angle steel for use as a limit. The main function of the chute 130 is to make the inclined support 300 convenient for disassembly and assembly, facilitate transportation, and be assembled on-site.

[0039] Please refer to Figure 2 and Figure 4 , in some embodiments, as a support for the inner side of the shaping panel 200, a top-opening bracket 400 is provided between the top of the casing 100 and the bottom of the shaping panel 200. Specifically, it can be evenly arranged corresponding to the four sides of the hollow part 210.

[0040] Please refer to Figure 6 , to ensure the quality of pile foundation steel bar processing, the steel reinforcement cage 1 is processed in sections, and each section is welded or mechanically connected. At this time, after lowering a section, support needs to be given to the steel reinforcement cage 1.

[0041] Please refer to Figure 5 , therefore, a steel reinforcement cage support 500 is also provided in this case. After lowering a section, the steel reinforcement cage support 500 is used at the position of the steel reinforcement cage's reinforcing stirrup, and another section is lifted and butt-connected, ensuring the quality and safety of the pile foundation steel reinforcement cage during lowering. Preferably, the steel reinforcement cage support 500 is a telescopic square steel.

[0042] Please refer to Figure 4 andFigure 5 , in some embodiments, the casing 100 is provided with an openable and closable cover plate 140. The inner fixing guardrail 230 is welded with hinges at one time, and the steel mesh is customized according to the pile foundation diameter and connected to the hinges. It can be opened and closed. When installing the steel reinforcement cage without performing punching operations, the protective net should be covered. During construction, the protective net can be opened and fixed to the inner guardrail. A conduit hole is reserved in the middle of the protective net, and the conduit can extend into it during the pile foundation pouring of hole cleaning without opening the protective net, which is safer.

[0043] As described above, the present case protects an assembled pile foundation construction platform, and all technical solutions identical or similar to the present case should be regarded as falling within the protection scope of the present case.
