Description

Technical Field

[0001] The utility model relates to the technical field of pipe pile driving, and in particular discloses a large-diameter pipe pile safety device. Background Art

[0002] With the development of urbanization in my country, high-rise buildings and underground projects have also entered a stage of rapid development. The scale of underground projects is increasing, and the problems of safety and economy in deep foundation pit support design are becoming increasingly prominent. Various foundation pit support types will appear in the same foundation pit, such as slope reduction + mixed reinforced prestressed concrete pipe pile support type.

[0003] Because the diameter of the mixed reinforced prestressed concrete pipe piles used as support piles is generally 600-800mm, there are problems with pile delivery in the original ground piling. The large-diameter pipe pile has a cavity in the middle of 540mm, and there is a risk of people falling in. After the pile is delivered, it is necessary to install a cover plate and then backfill to ensure safety. The current general treatment method is to cover the formwork after delivering the pile and then backfill. The formwork is easily damaged during the backfilling process and the hole is prone to collapse subsequently. A better treatment method is to weld the steel mesh and then cover the formwork and then backfill, which is time-consuming and labor-intensive. In addition, the soil is easy to fall out of the pipe pile during subsequent excavation to make the crown beam, increasing the workload of cleaning the hole.

[0004] Therefore, the above-mentioned defects of the existing mixed reinforced prestressed concrete pipe pile support type are currently urgent technical issues. Utility Model Content

[0026] In order to better understand the above technical solution, the above technical solution will be described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0027] like Figure 1 and Figure 2As shown, the first embodiment of the utility model proposes a large-diameter pipe pile safety device, including a bottom support plate 10, a support member 20 and a connector 30, wherein the bottom support plate 10 is arranged in the pile hole of the prestressed pipe pile 100, and is used to prevent soil and large rocks from falling into the pile hole of the prestressed pipe pile 100; the support member 20 is arranged above the prestressed pipe pile, and is used to support the pipe pile safety device; the connector 30 is vertically arranged between the bottom support plate 10 and the support member 20, and is used to connect the bottom support plate 10 and the support member 20. Among them, the bottom support plate 10, the support member 20 and the connector 30 can adopt existing mechanical parts, such as steel plates or steel bars, which are all within the protection scope of this patent.

[0028] Please see Figures 1 to 3 The large-diameter pipe pile safety device provided in this embodiment has a bottom support plate 10 in a circular shape. The bottom support plate 10 adopts a steel cage bottom support steel plate. The support member 20 is arranged in a triangular or square shape. The connecting member 30 is arranged in a U-shape or an eight-shape. The support member 20 and the connecting member 30 adopt steel rings. The support member 20 is arranged in the middle of the bottom support plate 10. The length of the support member 20 is greater than the inner diameter of the prestressed pipe pile 100, and the diameter of the bottom support plate 10 is smaller than the inner diameter of the prestressed pipe pile 100. The bottom support plate 10 and the connecting member 30 are fixedly connected by welding, and the connecting member 30 and the support member 20 are fixedly connected by welding.
