[0002] Hybrid prestressed reinforced concrete pipe piles are a new type of prestressed concrete pipe piles, also known as precast concrete piles. They are a new type of pipe piles that use a mixture of prestressed steel bars and non-prestressed steel bars. They combine the advantages of prestressed concrete and traditional reinforced concrete, and have higher strength, bearing capacity and earthquake resistance.
[0003] In the prior art, when the designed depth of the construction site is deep, bolts are usually used to connect two or more precast concrete piles together for use. However, the precast concrete piles usually do not have a good positioning device, and continuous adjustment is required to align the connection holes on the connecting flange, which increases the difficulty of docking. In addition, in the early stage of bolt connection, in order to avoid the connection holes from offset, workers are usually required to fix the precast concrete piles by hand or press them, which is inconvenient. Therefore, a hybrid prestressed reinforced concrete pipe pile is needed. Utility Model Content

[0006] Four limiting rods are fixedly connected to the inner surface of the positioning block, and the same slider is slidably connected to two corresponding limiting rods. Both sliders are fixedly connected to a fixed block, and springs are slidably sleeved on the outer surfaces of the four limiting rods.
[0007] According to the hybrid prestressed reinforced concrete pipe pile, the docking block is matched with the positioning groove, and the first flange plate and the second flange plate are both provided with a plurality of docking holes, so as to facilitate the docking between the two precast concrete piles.
[0008] According to the hybrid prestressed reinforced concrete pipe pile, one end of the spring is fixedly connected to the side surface of the slider, and the end of the spring away from the slider is fixedly connected to the side inner wall of the positioning block, so that the fixing block can quickly enter the fixing groove.
[0009] According to the hybrid prestressed reinforced concrete pipe pile, a slide groove is provided on the positioning block, and the outer surface of the sliding block is slidably connected to the slide groove, so that the sliding block can only move in the horizontal direction.
[0010] According to the hybrid prestressed reinforced concrete pipe pile, a movable hole is provided on the positioning block, and the outer surface of the fixed block is slidably connected to the movable hole, so that the fixed block can move smoothly.

[0023] This section will describe in detail the specific embodiments of the utility model. The preferred embodiments of the utility model are shown in the accompanying drawings. The purpose of the accompanying drawings is to supplement the description of the text part of the specification with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the utility model, but it cannot be understood as a limitation on the protection scope of the utility model.
[0024] Reference Figure 1-6 The utility model embodiment is a hybrid prestressed reinforced concrete pipe pile, which includes a precast concrete pile 1. The outer surfaces of the precast concrete pile 1 are respectively fixedly connected with a first flange 2 and a second flange 3. The first flange 2 and the second flange 3 are each provided with a plurality of docking holes 4. The inner surfaces of the precast concrete pile 1 are respectively fixedly connected with a connecting block 5 and a positioning block 8. The upper surface of the connecting block 5 is fixedly connected with a docking block 6. The docking block 6 is provided with a fixing groove 7. The positioning block 8 is provided with a positioning groove 9. The docking block 6 is adapted to the positioning groove 9.
[0025] Four limit rods 10 are fixedly connected to the inner surface of the positioning block 8, and the same slider 11 is slidably connected to the corresponding two limit rods 10. The two sliders 11 are fixedly connected to a fixed block 12. The outer surfaces of the four limit rods 10 are slidably sleeved with springs 13, one end of the spring 13 is fixedly connected to the side surface of the slider 11, and the end of the spring 13 away from the slider 11 is fixedly connected to the side inner wall of the positioning block 8. A slide groove 14 is provided on the positioning block 8, and the outer surface of the slider 11 is slidably connected to the slide groove 14. A movable hole 15 is provided on the positioning block 8, and the outer surface of the fixed block 12 is slidably connected to the movable hole 15. The movable hole 15 is adapted to the fixed groove 7. There are two movable holes 15 and they are distributed on the left and right, and the movable hole 15 is connected to the slide groove 14.
[0026] Working principle: When two precast concrete piles 1 need to be butt-jointed, the butt-jointing block 6 on the precast concrete pile 1 is inserted into the positioning groove 9 on another precast concrete pile 1 of the same type, so that the butt-jointing holes 4 of the first flange 2 and the second flange 3 on the two precast concrete piles 1 can correspond to each other, thereby realizing rapid positioning of the butt-jointing holes 4. At the same time, in the process of inserting the butt-jointing block 6 into the positioning groove 9, it will contact the inclined surfaces of the two fixing blocks 12. When the butt-jointing block 6 is gradually inserted into the positioning groove 9, the butt-jointing block 6 will squeeze the two fixing blocks 12 along the inclined surfaces of the fixing blocks 12 to move away from each other, so that the moving fixing block 12 can drive the slider 11 to move horizontally on the limit rod 10, and the fixing block 12 will squeeze the inner wall of the positioning block 8 during the movement. The spring 13 is then put in a tightened state. When the docking block 6 is fully inserted into the positioning groove 9, the movable hole 15 can be connected with the fixing groove 7, and the fixing block 12 can correspond to the fixing groove 7, and the docking block 6 can no longer contact the fixing block 12, so that the spring 13 is no longer restricted to rebound, so that the rebounding spring 13 can drive the slider 11 to reset in the slide groove 14, and then the moving slider 11 can drive the fixing block 12 to move. When the moving fixing block 12 enters the fixing groove 7, the docking block 6 can be fixed, so that the docking block 6 can no longer be separated from the positioning groove 9, so that the fixation between the two precast concrete piles 1 can be achieved, and then bolts are used to further reinforce the two precast concrete piles 1.
[0027] The embodiments of the present invention are described in detail above in conjunction with the accompanying drawings, but the present invention is not limited to the above embodiments. Various changes can be made within the knowledge scope of ordinary technicians in the technical field without departing from the purpose of the present invention.
