Description

Technical Field

[0001] The utility model relates to the technical field of municipal building materials, and more specifically to a prefabricated pipe pile for municipal construction. Background Art

[0002] In the field of municipal engineering construction, prefabricated pipe piles are widely used in various foundation projects. Their main function is to provide stable and reliable support for the upper buildings. Prefabricated pipe piles usually need to be connected at the construction site to achieve the pile length required by the design. At the same time, it is necessary to ensure that under complex geological conditions and variable external loads, the entire pile foundation structure has sufficient stability, durability and construction convenience.

[0003] Traditional prefabricated pipe pile connection methods mostly use simple welding or rely on a single connection component for connection. When facing lateral forces, such as in earthquake-prone areas or sites with large soil lateral pressure, traditional connection methods are difficult to provide sufficiently strong lateral constraints. Due to the lack of a stable lateral connection structure, pipe piles are prone to deformation, dislocation or even fracture at the connection parts under the action of lateral forces, which seriously threatens the safety and stability of the upper buildings. This problem of insufficient lateral stability may not only lead to engineering quality accidents, increase maintenance costs and project delays, but may also cause serious safety disasters in extreme cases, causing huge losses to the surrounding environment and people's lives and property. For this reason, we propose a prefabricated pipe pile for municipal construction. Utility Model Content

[0004] The technical problem to be solved by the utility model is to overcome the deficiencies of the prior art and provide a prefabricated pipe pile for municipal construction to solve the problem of insufficient lateral constraints of the prefabricated pipe pile for municipal construction during pile connection operations.

[0005] The technical solution adopted by the utility model to solve the above technical problems is:

[0006] A prefabricated pipe pile for municipal construction, comprising a cement pile, both ends of the cement pile are fixedly installed with a connection block, the connection block is symmetrically provided with two groups of connection grooves at one end away from the cement pile, the connection grooves are respectively provided with connection arc plates, the height of the connection arc plates is twice the depth of the connection grooves, the two groups of connection arc plates can be connected by a side locking assembly, one end of the connection block is provided with a positioning groove, the positioning groove is a trapezoidal slot hole, the positioning groove gradually narrows from the side away from the cement pile to the side close to the cement pile, the other end of the connection block is fixedly installed with a positioning block, the positioning block is a trapezoidal block, the size of the positioning block is adapted to the size of the positioning groove, and the positioning block gradually widens from the side away from the cement pile to the side close to the cement pile;

[0007] A latch assembly is arranged on the connecting arc plate, and the latch assembly includes a card slot and a card plate. A card slot is opened on the inner side of the connecting slot, and the card slot is an arc-shaped slot hole. Two groups of card plates are symmetrically fixedly installed in the middle position of the inner side of the connecting arc plate, and the position of the card plate is matched with the position of the card slot on the connecting slot, and the size of the card plate is matched with the size of the card slot.

[0008] The side locking assembly includes a connecting slot and a locking screw. The two groups of connecting slots are respectively opened at the two ends of the upper part of the connecting block, and the connecting slots pass through the connecting block and are connected with the two groups of connecting slots. The locking screw is fixedly installed at one end of the connecting arc plate. The position of the locking screw corresponds to the position of the connecting slot, and the outer diameter of the locking screw is adapted to the inner diameter of the connecting slot.

[0009] The side locking assembly also includes a locking groove and a locking screw. The locking groove is opened on the outer side of the connecting arc plate. The locking groove and the locking screw are respectively arranged at both ends of the connecting arc plate. The position of the locking groove corresponds to the position of the connecting slot hole. A locking screw is arranged in the locking groove. The locking screw slides through the connecting arc plate and extends to a position corresponding to the connecting slot hole. Threads are arranged on the outer side of the locking screw and the inner side of the locking screw tube. The locking screws on one group of connecting arc plates can be threadedly connected with the locking screw tubes on another group of connecting arc plates.

[0010] There are multiple locking grooves spaced apart on the wall surfaces on both sides of the card plate, and the locking grooves are truncated cone-shaped slots. The locking grooves gradually narrow from both sides of the card plate to the middle position of the card plate. There are multiple locking blocks fixedly installed on the inner side walls of the card slots at intervals, and the locking blocks are truncated cone-shaped blocks. The size of the locking blocks is adapted to the size of the locking grooves at the corresponding positions on the card plate.

[0011] A prefabricated pipe pile for municipal construction also includes a pile tip, and a connecting block is fixedly installed on the top of the pile tip.

[0012] The gaps between the two groups of connection blocks and the two groups of connection arc plates can also be welded by welding rods.

[0013] Compared with the prior art, the utility model has the following beneficial effects:

[0014] 1. In the utility model, the side locking assembly provides a strong lateral constraint for the connection of the cement pile. The connecting arc plate is threadedly connected to the locking screw and the locking screw tube to tightly fix the upper and lower connecting blocks together, forming a stable lateral connection structure, which effectively ensures the overall stability of the pipe pile in a complex lateral force environment.

[0015] 2. In the utility model, the locking action of the latch assembly in the vertical direction cooperates with the side locking assembly, the close fit between the clamping plate and the clamping slot, and the buckle between the locking block and the locking slot prevent the relative displacement of the upper and lower cement piles in the vertical direction. This all-round locking mechanism enables the pipe piles to be evenly and stably transferred between each section of the pipe piles when they are subjected to vertical loads, thus avoiding damage to the pipe piles due to local stress concentration, and further enhancing the overall stability and bearing capacity of the pipe pile structure.

[0016] 3. In the utility model, the positioning groove and positioning block design on the connecting block play an auxiliary positioning role when two groups of cement piles are connected. The positioning block enters the positioning groove from the narrow end, and gradually completes the connection as the upper cement pile descends. This unique shape coordination eliminates the need for overly complicated measurements and precise adjustment of equipment during the pile connection process. Construction workers can initially position the upper and lower cement piles relatively quickly, which improves the efficiency of the pile connection operation to a certain extent and promotes the smooth progress of the overall construction process.

[0017] 4. In the utility model, the pile tip and the cement pile are connected by the side locking assembly and the latch assembly which are the same as the ordinary connection, so that the installation process of the pile tip is simple and convenient. Before the piling construction, it is only necessary to connect the pile tip and the cement pile according to the operation process of pile connection. This unified connection method reduces the complexity of construction equipment and processes, and is convenient for construction personnel to quickly and accurately complete the installation of the pile tip at the construction site, thereby improving the overall efficiency of the piling operation. Whether in municipal engineering projects with soft soil foundation or hard soil foundation, the connection operation between the pile tip and the pipe pile can be carried out smoothly, thereby enhancing the construction adaptability of the pipe pile under different geological conditions.

[0018] 5. In the utility model, welding is used as an additional reinforcement method to further enhance the connection strength between the connecting block and the connecting arc plate, so that the mechanical properties of the entire pipe pile connection are significantly improved, and it can withstand greater loads and more complex stress environments, thereby improving the safety and reliability of the pipe pile structure during long-term use. At the same time, welding can fill the tiny gaps in the connection parts to form a continuous metal connector, further improving the sealing of the pipe pile, reducing the erosion and damage to the connection parts by external factors, and extending the service life of the pipe pile.
