[0033] The features and performance of the precast pipe piles and precast pipe pile systems of this application will be further described in detail below with reference to embodiments.
[0034] Example 1
[0035] like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5As shown, this application embodiment provides a precast pipe pile, including a prestressed reinforced concrete pile body 100 and two end steel plates 110 respectively connected to both ends of the prestressed reinforced concrete pile body 100. Four arc-shaped bolt holes 120 are respectively provided inside both ends of the prestressed reinforced concrete pile body 100. Each arc-shaped bolt hole 120 penetrates the corresponding end face and one side wall of the prestressed reinforced concrete pile body 100 at both ends. Four steel plate bolt holes 130 are respectively provided on the two end steel plates 110, communicating with the corresponding arc-shaped bolt holes 120. The arc shape of the precast pipe pile... Bolt holes 120 and corresponding steel plate bolt holes 130 are used for the arc bolts 200 to pass through and connect with the arc bolt holes 120 and corresponding steel plate bolt holes 130 of an adjacent precast pipe pile. In this embodiment, the four arc bolt holes 120 inside each end of the prestressed reinforced concrete pile body 100 are symmetrically arranged on both sides inside the prestressed reinforced concrete pile body 100. The four arc bolt holes 120 inside each end of the prestressed reinforced concrete pile body 100 are symmetrically arranged and respectively penetrate the two oppositely arranged side walls of the prestressed reinforced concrete pile body 100.
[0036] This application embodiment also provides a precast pipe pile system, which includes two precast pipe piles as described above and four arc bolts 200. The end steel plates 110 at one end of the two precast pipe piles press against each other. The four arc bolts 200 pass through the four arc bolt holes 120 and four corresponding steel plate bolt holes 130 at the end of one precast pipe pile and are then connected to the four arc bolt holes 120 and four corresponding steel plate bolt holes 130 at the end of another adjacent precast pipe pile by nuts.
[0037] The precast pipe pile and precast pipe pile system provided in this application embodiment have arc-shaped bolt holes 120 respectively set inside both ends of the prestressed reinforced concrete pile body 100 of the precast pipe pile, and the two ends of the arc-shaped bolt holes 120 respectively penetrate the corresponding end face and one side wall of the prestressed reinforced concrete pile body 100. The end steel plate 110 is provided with steel plate bolt holes 130 that communicate with the corresponding arc-shaped bolt holes 120. The arc-shaped bolt 200 can pass through the arc-shaped bolt hole 120 and the corresponding steel plate bolt hole 130 at the end of one precast pipe pile and then connect with the arc-shaped bolt hole 120 and the corresponding steel plate bolt hole 130 at the end of another adjacent precast pipe pile through a nut. In this way, the connection force of the two precast pipe pile ends is transmitted to the interior and side of the precast pipe pile through the arc-shaped bolt 200. On the one hand, it can effectively improve the overall structural strength, front and rear force coordination and resistance to structural deformation of the precast pipe pile system. On the other hand, it can also facilitate cross-construction installation and construction by operators, save construction time and improve construction efficiency.
[0038] In other alternative embodiments, the two ends of the prestressed reinforced concrete pile body 100 may be provided with two, three, four or more arc-shaped bolt holes 120 respectively.
[0039] In other alternative embodiments, the arc-shaped bolt holes 120 provided inside each end of the prestressed reinforced concrete pile body 100 can also be arranged symmetrically or asymmetrically.
[0040] Example 2
[0041] like Figure 6 As shown, this application provides a precast pipe pile, which has a structure that is roughly the same as the precast pipe pile provided in embodiment 1. The difference is that in this embodiment, the end steel plate 110 at one end of the prestressed reinforced concrete pile body 100 protrudes to form a columnar positioning part 140, and the end steel plate 110 at the other end of the prestressed reinforced concrete pile body 100 is recessed to form a positioning groove 150 that is correspondingly engaged with the positioning part 140.
[0042] The precast pipe piles provided in this application embodiment have protruding positioning parts 140 and positioning grooves 150 corresponding to the positioning parts 140 respectively provided on the end steel plates 110 at both ends of the prestressed reinforced concrete pile body 100. This allows for convenient positioning of the ends of two adjacent precast pipe piles when they are pressed together. When the positioning part 140 at the end of the precast pipe pile is engaged with the positioning groove 150 at the end of another adjacent precast pipe pile, the bolt holes 130 on the steel plate at the end of one precast pipe pile are aligned with the bolt holes 130 on the steel plate at the end of another precast pipe pile, allowing the arc bolts 200 to pass through for connection. This effectively improves the construction efficiency of aligning and connecting two adjacent precast pipe piles.
[0043] Example 3
[0044] like Figure 7 As shown, this application provides a precast pipe pile, which has a structure that is roughly the same as the precast pipe pile provided in embodiment 1. The difference is that in this embodiment, an arc bolt tube 160 corresponding to the arc bolt hole 120 is embedded in the prestressed reinforced concrete pile body 100, and an arc bolt hole 120 is formed inside the arc bolt tube 160.
[0045] The precast pipe piles provided in this application form arc bolt holes 120 by pre-embedding arc bolt pipes 160 in the prestressed reinforced concrete pile body 100. This facilitates the processing of arc bolt holes 120 in the prestressed reinforced concrete pile body 100, and uses arc bolt pipes 160 in conjunction with arc bolts 200 to connect two adjacent precast pipe piles to form a stable whole.
[0046] Example 4
[0047] like Figure 8 and Figure 9As shown, this application embodiment provides a precast pipe pile, which has a structure that is roughly the same as the precast pipe pile provided in embodiment 3. The difference is that in this embodiment, the two ends of the prestressed reinforced concrete pile body 100 are respectively provided with embedded steel plates 170. The arc-shaped bolt pipes 160 embedded in the corresponding ends of the prestressed reinforced concrete pile body 100 pass through and are connected to the embedded steel plates 170. The embedded steel plates 170 are connected to four ribs 171 embedded in the prestressed reinforced concrete pile body 100. The outer wall of the arc-shaped bolt pipe 160 protrudes to form two stiffening plates 180.
[0048] The precast pipe pile provided in this application embodiment uses pre-embedded steel plates 170 embedded in the prestressed reinforced concrete pile body 100 and sleeved on each of the corresponding arc bolt pipes 160. The pre-embedded steel plates 170 can connect each arc bolt pipe 160 into a whole and tightly connect it with the prestressed reinforced concrete pile body 100, thereby improving the structural strength of each arc bolt pipe 160 and ensuring the stable limitation of the position of the arc bolt 200 passing through each arc bolt pipe 160.
[0049] The embedded steel plate 170 is connected to four ribs 171 embedded in the prestressed reinforced concrete pile body 100. The outer wall of the arc bolt pipe 160 protrudes to form two stiffening plates 180. The ribs 171 and stiffening plates 180 can be used to further improve the connection tightness between the embedded steel plate 170 and the arc bolt pipe 160 and the prestressed reinforced concrete pile body 100, and improve the overall structural strength of the precast pipe pile.
[0050] In other alternative embodiments, each arc bolt hole 120 is provided with an elastic rubber sleeve fitted on the corresponding arc bolt 200. The elastic rubber sleeve can protect and limit the corresponding arc bolt 200 passing through the arc bolt hole 120, thereby buffering the arc bolt 200 when it is under force and playing a protective role, improving the stress coordination and deformation resistance of the precast pipe pile system.
[0051] The embodiments described above are some, but not all, of the embodiments of this application. The detailed description of the embodiments of this application is not intended to limit the scope of the claimed application, but merely to illustrate selected embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of this application without inventive effort are within the scope of protection of this application.
