Description

Technical Field

[0001] The utility model relates to the technical field of pile foundation construction, in particular to a prefabricated concrete reinforcement pile. Background Art

[0002] According to the manufacturing method of pile foundation, it can be divided into precast piles and cast-in-place piles. Precast square piles are a kind of precast piles, that is, piles with a rectangular cross-section. They are widely used in various fields such as roads and bridges. Precast square piles are directly transported to the construction site after being manufactured in the factory, and then the precast piles are pre-buried in the foundation by mechanical vibration. However, since concrete square piles are made by pouring concrete and steel bars, although the strength is not low, the conical surface of the bottom is easy to be damaged due to the high pressure during the embedding process, and it does not have the function of reinforcing and supporting the top and bottom openings, which makes the overall strength low, resulting in deformation and cracking problems during the installation process. Utility Model Content

[0003] In view of this, in order to solve the problems existing in the technical background, the utility model proposes a prefabricated concrete reinforcement pile, and the specific technical solution is as follows:

[0004] A precast concrete reinforcement pile comprises a pile body, wherein the pile body is formed by connecting an inner steel cage and an outer steel cage, concrete is poured into the inner and outer steel cages to form the pile body, a conical block is provided below the pile body, the block is connected to supporting steel bars, the supporting steel bars are located in the middle of the pile body, and one end of the supporting steel bars, the inner steel cage and the outer steel cage are all connected to a pad.

[0005] Furthermore, the cone block and the pad are both made of metal.

[0006] Furthermore, the inner steel cage is arranged inside the outer steel cage, and the contact surfaces of the inner steel cage and the outer steel cage are fixed by welding.

[0007] Furthermore, the outer steel cage and the inner steel cage are both woven from main bars and stirrups.

[0008] Furthermore, a groove is formed on the top side wall of the pile body to increase the contact surface between the pile body and the soil, thereby improving the friction force and increasing the resistance of the pile body.

[0009] The above technical solution has the following beneficial effects:

[0010] The utility model adopts an inner steel cage and an outer steel cage and a pile body formed by pouring concrete. In addition, a pad is provided on the top of the pile body to improve the deformation resistance of the top. The cone block under the pile body and the pad on the top are made of metal material. The metal cone block has higher strength. When the pile body is buried in the ground, it is easy for the cone surface part of the bottom end surface of the precast concrete pile body to be damaged.

[0015] The utility model is further described below in conjunction with the accompanying drawings.

[0016] Example 1: Figure 1-3 A precast concrete reinforcement pile shown includes a pile body 1, which is formed by connecting an inner steel cage 5 and an outer steel cage 4. Concrete is poured in the inner steel cage 5 and the outer steel cage 4 to form the pile body 1. A conical block 2 is provided under the pile body 1. The block 2 is connected to a supporting steel bar 7. The supporting steel bar 7 is located in the middle of the pile body 1. The supporting steel bar 7, the inner steel cage 5 and one end of the outer steel cage 4 are all connected to a pad 6.

[0017] The cone block 2 and the pad 6 are both made of metal. The inner steel cage 5 is arranged inside the outer steel cage 4. The contact surface between the inner steel cage 5 and the outer steel cage 4 is fixed by welding. The outer steel cage 4 and the inner steel cage 5 are both woven with main bars and stirrups. The top side wall of the pile body 1 is provided with a groove 3 for increasing the contact surface between the pile body 1 and the soil, thereby improving friction and increasing the resistance of the pile body 1.

[0018] The cone block 2 and the pad 6 in this embodiment are made of alloy steel. The cross-sections of the outer steel cage 4 and the inner steel cage 5 in this embodiment are both square. The diagonal length of the square of the projection surface of the inner steel cage 5 is equal to the side length of the square of the projection surface of the outer steel cage 4. The inner steel cage 5 is overlapped in the inner cavity of the outer steel cage 4, so that the inner steel cage 5 is connected to the outer steel cage 4, and the contact between the inner steel cage 5 and the outer steel cage 4 is welded together.

[0019] During specific use, the pile body 1 is inserted into the soil with the cone facing downward, and the pile body 1 is pushed downward. When the lower end of the pile body 1 reaches the predetermined working position, the downward push is stopped, and the top of the pile body 1 is exposed to the ground. It can be determined according to actual construction needs, and this embodiment does not make specific limitations on this.

[0020] The utility model adopts a pile body 1 formed by an inner steel cage 5 and an outer steel cage 4 and poured with concrete. In addition, a pad 6 is provided on the top of the pile body 1 to improve the deformation resistance of the top. The cone block 2 below the pile body 1 and the pad 6 on the top are made of metal material. The cone block 2 made of metal material has higher strength. When the pile body 1 is buried in the ground, it is easy for the cone surface part of the bottom end surface of the precast concrete pile body 1 to be damaged.
