Description

Technical Field

[0001] The present application relates to the technical field of deep foundation pit support, and specifically to a welded pile-free structure for deep foundation pit support. Background Art

[0002] Deep foundation pit refers to a foundation pit project with an excavation depth of more than 5 meters (including 5 meters), or a project with a depth of less than 5 meters but with particularly complex geological conditions, surrounding environment and underground pipelines. This type of project usually involves earth excavation, support and precipitation, etc., aiming to ensure the safety and stability of the construction process. The excavation and support of deep foundation pits are important links in construction projects, especially in urban construction. Due to the influence of underground pipelines and surrounding buildings, the safety and stability of deep foundation pit projects are particularly important.

[0003] The existing deep foundation pit needs to be supported by pile boards and enclosures during the excavation process. However, the sealing effect of the existing pile boards when they are connected is poor, the overall stability of the pile boards is low, and it is not convenient to connect the corners of the pile boards. Utility Model Content

[0004] In response to the shortcomings of the prior art, the present application provides a welded pile-free structure for supporting deep foundation pits, which has the advantages of being easy to connect and seal the pile plates, and convenient to connect and install the pile plates at the corners. It solves the problem that the existing deep foundation pits need to use pile plates and enclosures for support during the excavation process, but the existing pile plates have poor sealing effects when connected, and it is not convenient to connect the pile plates at the corners.

[0005] To achieve the above-mentioned purpose, the present application provides the following technical solutions: a welded pile-free structure for supporting a deep foundation pit, comprising a pile plate, both ends of the pile plate are provided with interlocking grooves, the pile plates are slidably connected through the interlocking grooves, the inner wall of the pile plate is fixedly connected with two first enclosures, the inner wall of the pile plate is fixedly connected with two second enclosures, four inner supports are arranged inside the pile plate, the two ends of the inner supports are respectively fixedly connected to the outer surfaces of the first enclosure and the second enclosure, and two pairs of supports are fixedly connected between the two first enclosures.

[0006] Through the above scheme, since the existing deep foundation pit needs to be supported by pile plates and enclosures during the excavation process, the sealing effect of the existing pile plates when docked is poor, and it is not convenient to dock the pile plates at the corners. By arranging interlocking grooves at both ends of the pile plates, the pile plates can be interlocked and docked, thereby improving the sealing effect of the pile plate docking installation and increasing the overall stability of the pile plates. By arranging docking plates at the corner docking points of the pile plates, the two pile plates at the corners can be connected, thereby facilitating the docking of the corners of the pile plates.

[0007] Furthermore, the corner joints of the pile plates are all provided with docking plates, and the docking plates are respectively slidably connected to the pile plates through interlocking grooves.

[0008] Through the above scheme, the two pile plates at the corner are connected by the butt joint plate, which facilitates the butt joint operation of the pile plates at the corner and improves the overall sealing effect of the pile plates.

[0009] Furthermore, two reinforcement plates are provided inside the pile plate, and two ends of the reinforcement plates are respectively fixedly connected to the outer surface of the support.

[0010] Through the above scheme, the support is reinforced, the supporting capacity of the support is increased, and the stability of the first enclosure is increased.

[0011] Furthermore, two first bottom plates are fixedly connected to the inner wall of the pile plate, and the upper surfaces of the first bottom plates are respectively in contact with the bottom surface of the first enclosure.

[0012] Through the above solution, the first enclosure is supported, which facilitates the welding and installation of the first enclosure and also increases the stability of the first enclosure.

[0013] Furthermore, two second bottom plates are fixedly connected to the inner wall of the pile plate, and the upper surfaces of the second bottom plates are respectively fixedly connected to the bottom surfaces of the second enclosures.

[0014] Through the above solution, the second enclosure is supported, which facilitates the welding and installation of the second enclosure and also increases the stability of the second enclosure.

[0015] Furthermore, both ends of each pair of supports are fixedly connected with a first mounting block, and each of the first enclosures is provided with four first mounting grooves inside, and the first mounting blocks are respectively slidably plugged into the first enclosures through the first mounting grooves.

[0016] Through the above solution, the support can be installed through the first installation block and the first installation groove, which is convenient for welding the support.

[0017] Furthermore, both ends of each inner support are fixedly connected with a second mounting block, and each second enclosure has two second mounting grooves formed inside, and the second mounting block is slidably connected with the first enclosure and the second enclosure through the first mounting groove and the second mounting groove respectively.

[0018] Through the above solution, the inner support can be installed through the second installation block and the first installation groove and the second installation groove, which is convenient for welding the inner support.

[0019] Furthermore, the outer surface of the pile plate is coated with an anti-rust coating, and the outer surface of the docking plate is coated with an anti-rust coating.

[0020] Through the above scheme, the pile plate and the butt joint plate are protected to prevent the pile plate and the butt joint plate from being easily corroded.

[0021] Compared with the prior art, the technical solution of this application has the following beneficial effects:

[0022] The welded pile-free structure for supporting a deep foundation pit has interlocking grooves at both ends of the pile plates to enable the pile plates to interlock and butt together, and has butt plates at the corner butt joints of the pile plates to enable the two pile plates at the corner to be connected, thereby improving the sealing effect of the pile plate butt joint installation, increasing the overall stability of the pile plates, and facilitating butt jointing of the corners of the pile plates, thereby solving the problems of poor sealing effect when the existing pile plates are butt jointed and the inconvenience of butt jointing at the corners of the pile plates.
