Abstract
Description
Technical Field
[0001] This utility model relates to the field of building engineering technology, specifically to a high-bearing-capacity concrete pile with built-in reinforcing steel bars. Background Technology
[0002] Concrete piles are piles made of concrete, including ordinary reinforced concrete and prestressed concrete. They have advantages such as saving timber and steel, durability, and low cost, and are widely used in the foundation engineering of hydraulic structures, industrial buildings, civil buildings, and bridges. They are also often used for anti-sliding or water-proofing of slopes and foundation pits. Precast concrete piles, on the other hand, are pre-produced concrete piles that can be used directly in building construction, improving construction efficiency.
[0003] The existing concrete pile reinforcement cage structure is simple and prone to cracking due to stress concentration. In addition, the surface of the soil pile is easily washed by rainwater, which makes it susceptible to corrosion and affects the life of the soil pile.
[0004] Therefore, in view of this, we studied and improved the existing structure and its shortcomings, and proposed a high-bearing-capacity concrete pile with built-in reinforcing steel bars in order to achieve a more practical value. Utility Model Content
[0005] The purpose of this invention is to provide a high-bearing-capacity concrete pile with built-in reinforcing steel bars to solve the problems mentioned in the background art.
[0006] To achieve the above objectives, this utility model provides the following technical solution: a high-bearing-capacity concrete pile with built-in reinforcing steel bars, comprising a soil pile base and a lateral protruding cap. The lateral protruding cap is horizontally stacked on the outside of the soil pile base. Reinforcing steel bars are built into the inside of the soil pile base, and multiple sets of reinforcing steel bars are arranged in a circular pattern. Spiral hoops are sleeved on the outside of the multiple sets of reinforcing steel bars. Positioning plates are horizontally arranged at the upper and lower ends of the spiral hoops. An inner circular groove is provided in the middle of the soil pile base, and a cylinder is provided on the inner side of the inner circular groove.
[0007] Furthermore, the spiral stirrups and multiple sets of reinforcing bars are arranged in a spiral surround pattern.
[0008] Furthermore, the spiral stirrups and the multiple sets of reinforcing bars form a wire fixing structure.
[0009] Furthermore, the lateral protrusions are arranged in a stacked manner, and the lateral protrusions are inclined outwards around their perimeter.
[0010] Furthermore, the surface of the slanted protrusion cap is coated with an epoxy asphalt anti-corrosion layer.
[0011] Furthermore, the inner groove and the cylinder are dimensionally interlocked.
[0012] Furthermore, the soil pile foundation adopts an overall structure of outer square and inner circle.
[0013] This utility model provides a high-bearing-capacity concrete pile with built-in reinforcing steel bars, which has the following beneficial effects:
[0014] 1. In this utility model, the entire concrete pile adopts an outer square and inner circle structure. The outer rectangular structure ensures the portability and stability of the soil pile during fixing and erection, and facilitates connection with other fixing components. The inner circular groove structure can better receive the transmitted pressure by utilizing the circular structure of its inner wall, avoid stress concentration, and increase the high bearing capacity of the concrete pile.
[0015] 2. In this utility model, the concrete pile uses reinforcing steel bars as the main structure. Several high-strength reinforcing steel bars with a diameter of 16-32mm are evenly distributed along the axis of the pile. The interior of the concrete pile is provided with continuous spiral steel bars surrounding the reinforcing steel bars, with a spacing of 100-300mm, which are used to restrain the concrete and enhance its shear resistance.
[0016] 3. The side-sloping protrusion cap designed on the outside of the soil pile foundation of this utility model has multiple inclined surfaces arranged to form multiple inclined layers. When it comes into contact with rainwater or other corrosive substances, it can pre-block them and guide them along the inclined surfaces, reducing the contact between the internal foundation and rainwater and other substances, greatly increasing the chance of corrosion, and avoiding the situation of surface peeling and flaking of the internal soil pile foundation.
[0017] The entire outer surface of the pile is coated with an epoxy asphalt or polymer mortar anti-corrosion layer, and the internal steel reinforcement cage is galvanized or wrapped with a rust inhibitor. Attached Figure Description

When in contact with rainwater or other corrosive substances, they can pre-block them and guide them along the inclined surfaces, reducing the contact between the internal foundation and rainwater and other substances, greatly increasing the chance of corrosion, and preventing the surface of the internal soil pile foundation 1 from peeling off or crumbling.
[0028] The entire outer surface of the pile is coated with an epoxy asphalt or polymer mortar anti-corrosion layer, and the internal steel reinforcement cage is galvanized or wrapped with a rust inhibitor.
