Description

Technical Field

[0001] The utility model relates to the technical field of construction engineering, in particular to a double-row prefabricated pipe pile supporting and binding device. Background Art

[0002] At present, the double-row prefabricated pipe pile support technology used in the field of water conservancy construction worldwide generally has some problems that need to be improved. The conventional practice is to use concrete beams or steel beams. However, the existing coupling beam design and installation process have obvious limitations:

[0003] First, the concrete beam structure is often complex and the construction process is cumbersome. The ring beam of the supporting structure needs to be roughened, and the construction process is complicated, which not only prolongs the construction period, but also consumes a lot of manpower and material resources in the installation and disassembly process. Especially in the case of emergency repairs or temporary support needs, this type of connecting beam cannot be quickly deployed or removed, which greatly restricts the progress and flexibility of the project.

[0004] Secondly, the steel structure beam is not ideal in terms of load-bearing capacity transmission. The displacement of the upper structure is the focus of monitoring in the construction of prefabricated pipe pile support. The upper stiffness of the steel structure beam does not meet the requirements, making it difficult to fully ensure the uniform force and coordinated work between the double rows of prefabricated pipe piles, thus limiting the overall support effect and safety.

[0005] In addition, the prior art also uses a steel-concrete casting integrated construction structure to solve the above-mentioned construction troubles or low structural strength problems, but this integrally cast structure has the problem of being troublesome to dismantle later. Utility Model Content

[0006] The purpose of the utility model is to provide a double-row prefabricated pipe pile support and tie device, which, by combining channel steel with a steel-concrete structure, creates a novel structure that has the characteristics of rapid installation and convenient dismantling, while ensuring effective load transfer and common support between the double-row piles.

[0007] To achieve the above purpose, the utility model is implemented through the following technical solutions:

[0008] A double-row prefabricated pipe pile support and anchoring device includes a connecting beam assembly connecting the prefabricated pipe piles, the connecting beam assembly includes channel steel and a steel-concrete structural beam, at least one channel steel is fixedly installed on each row of prefabricated pipe piles, and the installation direction of the channel steel is parallel to the arrangement direction of the prefabricated pipe piles; the steel-concrete structural beam is fixedly arranged on the channel steel perpendicular to the channel steel.

[0009] Furthermore: a plurality of steel-concrete structural beams are provided, and the plurality of steel-concrete structural beams are evenly spaced and arranged in the intervals between the prefabricated pipe piles.

[0010] Furthermore: each row of prefabricated pipe piles is provided with an upper and lower layer of channel steel.

[0011] Furthermore: 4 channel steels are arranged on each row of prefabricated pipe piles, including two channel steels on the upper layer and two channel steels on the lower layer.

[0012] Further: the channel steel is installed on the top of the prefabricated pipe pile.

[0013] Furthermore: the channel steel is welded and installed on the prefabricated pipe piles.

[0014] Furthermore: the steel-concrete structural beam is installed on the channel steel by welding.

[0015] Compared with the original technology, the utility model has the following beneficial effects:

[0016] 1. The structural design of the overlapping middle channel steel and steel-concrete structural beam of the utility model ensures that the load can be effectively transferred between the double rows of prefabricated pipe piles, realizes common force, enhances the overall stability of the support system, and meets the requirements of water conservancy projects for high bearing capacity and reliability.

[0017] Second, the tie-tying device of the utility model has a simple structure and is easy to build. The welded fixed channel steel structure and the layered and spaced steel-concrete structural beams significantly simplify the on-site installation process of the connecting beam, allowing the connecting beam to be quickly and accurately assembled in place, greatly shortening the construction period. Similarly, due to the clear structure and clear connection, the later dismantling work can also be more convenient, reducing the project cost and improving the construction efficiency.

[0018] 3. The modular design of the tie-down device of the utility model can adjust the number of layers of the connecting beam assembly and the spacing of the steel-concrete structural beams according to actual engineering needs. It has good adaptability and flexibility and is suitable for double-row prefabricated pipe pile support application scenarios with different geological conditions and engineering scales.

[0026] like Figure 1-3 As shown: a double-row prefabricated pipe pile support and anchoring device, including a connecting beam assembly connecting each prefabricated pipe pile 1, and a channel steel 2 welded and installed on the top of the prefabricated pipe pile 1.

[0027] The connecting beam assembly includes a channel steel 2 and a steel-concrete structural beam 3. At least one channel steel 2 is fixedly installed on each row of prefabricated pipe piles 1. The installation direction of the channel steel 2 is parallel to the arrangement direction of the prefabricated pipe piles 1; the steel-concrete structural beam 3 is fixedly arranged on the channel steel 2 perpendicularly to the channel steel 2.

[0028] There are four steel-concrete structural beams 3, which are evenly spaced and arranged in the intervals of the prefabricated pipe piles 1. Each row of prefabricated pipe piles 1 is provided with two layers of channel steels 2, two of which are in the upper layer and two in the lower layer. The steel-concrete structural beams 3 are installed on the channel steels 2 by welding.

[0029] The working principle of the utility model is as follows:

[0030] First, according to the design plan, channel steels 2 and steel-concrete structural beams 3 of corresponding specifications are manufactured. The number and position of the channel steels 2 are configured such that two layers are arranged on each row of prefabricated pipe piles 1, with two channels on each layer.

[0031] Install channel steel 2: At the preset position on the top of the double-row prefabricated pipe piles 1, weld and fix the channel steel 2 to the top steel sleeve of each row of prefabricated pipe piles 1, ensuring that the channel steel is parallel to the arrangement direction of the prefabricated pipe piles 1, so as to serve as the basic structure of the connecting beam assembly.

[0032] Installing steel-concrete structural beams 3: On the channel steel 2, multiple steel-concrete structural beams 3 are installed according to the principle of evenly spaced arrangement. These steel-concrete structural beams 3 are fixedly arranged perpendicular to the channel steel and can be firmly installed on the channel steel 2 by welding to ensure that a connecting beam assembly with the channel steel 2 is formed in a stable connection.

[0033] Adjustment and adaptive installation: According to the needs of the actual project, the number of layers of channel steel 2 can be increased or decreased and the spacing between the steel-concrete structural beams 3 can be adjusted to flexibly adapt to changes in different geological conditions and project scales, thereby achieving modular rapid installation and adjustment.

[0034] The working principle of the utility model is mainly to form a connection system with good mechanical properties and high construction convenience through the effective combination of channel steel 2 and steel-concrete structural beam 3. In practical applications, when an external load is applied to a single prefabricated pipe pile 1, the connecting beam assembly composed of channel steel and steel-concrete structural beam 3 can quickly and effectively disperse the load to adjacent prefabricated pipe piles 1, ensuring that the double-row pile bodies are subjected to common force, thereby improving the bearing capacity and stability of the overall support structure.

[0035] During the construction process, the use of welded channel steel 2 and layered and spaced steel-concrete structural beams 3 greatly simplifies on-site installation and removal operations, significantly reducing construction time and costs. At the same time, due to the characteristics of modular design, the tie-in device can be quickly and accurately installed and disassembled according to the specific requirements of the project, thus being widely adapted to various water conservancy project application scenarios.

[0036] The above implementation is only to illustrate the technical concept and features of the utility model, and its purpose is to enable people familiar with this technology to understand the content of the utility model and implement it accordingly, and it cannot be used to limit the protection scope of the utility model. Any equivalent changes or modifications made according to the spirit of the utility model should be included in the protection scope of the utility model.
