Description

Technical Field

[0001] This utility model relates to the field of concrete pipe pile technology, specifically to a building concrete pipe pile. Background Technology

[0002] Concrete pipe piles are a type of precast pile widely used in building foundation engineering. They have many advantages and characteristics. Concrete pipe piles can be divided into prestressed concrete pipe piles, prestressed thin-walled concrete pipe piles, and prestressed high-strength concrete pipe piles. The production process of concrete pipe piles requires the selection of steel bars that meet the requirements. These bars are cut, bent, and welded according to the design specifications to form the steel cage of the pipe pile. The quality of the steel bars and the welding process directly affect the bearing capacity and durability of the pipe pile. Cement, aggregates, water, admixtures, and other raw materials are mixed according to a certain mix ratio to form a uniform concrete mixture. The steel cage is placed in a mold, and then the concrete mixture is poured into the mold. A high-speed rotating centrifuge causes the concrete to tightly fill the mold under the action of centrifugal force, forming a hollow pipe pile shape. After curing, the pile is demolded, thus producing a concrete pipe pile.

[0003] Currently, in existing technologies, concrete pipe piles, after proper design and production, can withstand large vertical loads and provide stable foundation support for buildings. However, in actual construction, when the pile length is insufficient and splicing is required, welding is used to connect the concrete pipe piles. The welding quality is greatly affected by the construction environment and the welder's skill level, thus affecting the quality of the splicing. Moreover, when the concrete pipe pile is driven into the foundation pit, it will be subjected to horizontal forces from the soil, which can easily cause the middle of the concrete pipe pile to crack. Therefore, a new type of concrete pipe pile is proposed to solve the above problems. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a type of concrete pipe pile for construction, which has the advantages of high strength and easy splicing. It solves the problem that in actual construction, when the pile length is insufficient and splicing is required, the concrete pipe piles need to be connected by welding. However, the welding quality is greatly affected by the construction environment and the welder's skill level, thus affecting the quality of the splicing. Moreover, when the concrete pipe pile is sunk into the foundation pit, it will be subjected to the horizontal force of the soil, which can easily cause the middle part of the concrete pipe pile to crack.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a building concrete pipe pile, comprising a pipe pile body, wherein an outer protective ring is provided on the pipe pile body, and an external reinforcing bar is provided on the outer protective ring;

[0006] A plastic injection ring is fixedly connected to the outer surface of the pipe pile body. One end of the external reinforcing rib penetrates and extends into the interior of the plastic injection ring. A concrete pouring layer is poured on the outer surface of the pipe pile body. The concrete pouring layer is located between the outer protective ring and the plastic injection ring. A butt joint concrete component is fixedly installed on the inner wall of the pipe pile body. A support component for strengthening the prestress of the pipe pile body is installed on the inner wall of the pipe pile body. An internal reinforcing rib is pre-embedded inside the butt joint concrete component.

[0007] Furthermore, the outer protective ring is fixedly installed on the outer surface of the pipe pile body, and one end of the external reinforcing rib is pre-embedded inside the outer protective ring.

[0008] Furthermore, the injection ring has a connecting hole inside, one end of the external reinforcing rib passes through and extends into the connecting hole and is fixedly connected to the inner wall of the connecting hole, and both the injection ring and the outer protective ring have injection holes for pouring concrete layers inside.

[0009] Furthermore, the concrete docking component is a concrete docking cylinder, the outer surface of which is fixedly connected to the inner wall of the pipe pile body, and the upper part of which is conical.

[0010] Furthermore, the supporting component includes two concrete support rings, both of which are fixedly installed on the inner circumferential wall of the pipe pile body, and one end of the built-in reinforcing rib passes through the two concrete support rings.

[0011] Furthermore, both the external reinforcing ribs and the internal reinforcing ribs are made of spiral steel bars.

[0012] Compared with the prior art, the technical solution of this application has the following beneficial effects:

[0013] This concrete pipe pile, by incorporating an outer protective ring and an injection ring, allows concrete to be poured into the outer protective ring and injection ring through the grouting holes on the injection ring after the pile body is driven, until the poured concrete solidifies and forms a concrete layer on the outer surface of the pipe pile body. This increases the strength of the middle part of the pipe pile body. Furthermore, the use of two concrete rings in the support components to carry built-in reinforcing bars enhances the prestressing effect on the inner wall of the pipe pile body. And the use of butt-joint concrete components facilitates the splicing of two pipe pile bodies, making the connection of two pipe pile bodies more convenient and faster, thereby enhancing the practicality of this concrete pipe pile.

[0020] In this implementation, a plastic injection ring 3 is fixedly connected to the outer surface of the pipe pile body 1. One end of the external reinforcing rib 4 penetrates and extends into the interior of the plastic injection ring 3. A concrete pouring layer 5 is poured on the outer surface of the pipe pile body 1. The concrete pouring layer 5 is located between the outer protective ring 2 and the plastic injection ring 3. A butt joint concrete component 6 is fixedly installed on the inner wall of the pipe pile body 1. The butt joint concrete component 6 is a concrete butt joint cylinder. The outer surface of the concrete butt joint cylinder is fixedly connected to the inner wall of the pipe pile body 1. The upper part of the concrete butt joint cylinder is conical, which facilitates the splicing operation of two pipe pile bodies 1. A support component 7 for strengthening the prestress of the pipe pile body 1 is installed on the inner wall of the pipe pile body 1. An internal reinforcing rib 8 is pre-embedded inside the butt joint concrete component 6. Both the external reinforcing rib 4 and the internal reinforcing rib 8 are spiral steel bars, which enhances the internal and external load of the pipe pile body 1.

[0021] The injection ring 3 has a connecting hole inside, and one end of the external reinforcing rib 4 passes through and extends into the connecting hole and is fixedly connected to the inner wall of the connecting hole. Both the injection ring 3 and the outer protective ring 2 have injection holes for pouring concrete layer 5, so that concrete can be poured between the injection ring 3 and the outer protective ring 2 through the injection holes, so that concrete layer 5 is formed on the outer surface of the middle part of the pipe pile body 1.

[0022] In addition, the support component 7 includes two concrete support rings, both of which are fixedly installed on the inner circumferential wall of the pipe pile body 1. One end of the built-in reinforcing rib 8 passes through the two concrete support rings, which facilitates the use of the two concrete support rings to stabilize the built-in reinforcing rib 8 and to support the inner wall of the pipe pile body 1.

[0023] By adopting the above technical solution, concrete is poured between the outer protective ring 2 and the injection ring 3 through the injection hole on the injection ring 3 until the poured concrete solidifies and forms a concrete pouring layer 5 on the outer surface of the pipe pile body 1, thereby increasing the strength of the middle part of the pipe pile body 1. Furthermore, the two concrete rings in the support component 7 are equipped with built-in reinforcing ribs 8, thereby enhancing the prestressing effect on the inner wall of the pipe pile body 1. Additionally, the use of the butt joint concrete component 6 facilitates the splicing of two pipe pile bodies 1, making the connection of two pipe pile bodies 1 more convenient and faster.

[0024] The working principle of the above embodiments is as follows:

[0025] In the construction of this concrete pipe pile, the pipe pile body 1 is driven into the ground using a static pressure pile driver. Then, concrete is injected between the injection ring 3 and the outer protective ring 2 through the injection hole on the injection ring 3, so that a concrete pouring layer 5 is formed on the outer surface of the middle part of the pipe pile body 1. After the concrete pouring layer 5 is completely solidified, another pipe pile body 1 is lifted up by hoisting equipment and aligned with the pipe pile body 1 driven into the ground. The pipe pile body 1 is then fitted onto the mating concrete part 6 on the top of the pipe pile body 1 driven into the ground. Then, the second pipe pile body 1 is driven into the ground using a static pressure pile driver, thus completing the pile splicing operation. The strength of the pipe pile body 1 is enhanced by the concrete pouring layer 5 and the external reinforcing bar 4, so that the pipe pile body 1 can withstand horizontal prestress.
