Description

Technical Field

[0001] This utility model belongs to the field of building technology, and in particular relates to a concrete pipe pile for soft foundation. Background Technology

[0002] Concrete pipe piles are precast tubular components made of concrete, widely used in the foundation construction of buildings, bridges, municipal engineering projects, and other fields. With their high strength, good durability, and convenient construction, they have become important structural components for enhancing the bearing capacity of the foundation and transferring the load of the superstructure to deep, solid soil layers, playing a crucial role, especially in projects with complex geological conditions such as soft soil foundations.

[0003] In existing concrete pipe pile technology, its structure mainly consists of concrete columns, end plates, and reinforcing frames. The concrete columns, as the main body of the pipe pile, bear the main load transfer task; the end plates are set at both ends of the concrete columns for connecting the pipe piles and enhancing the structural stability of the pipe pile ends; the reinforcing frames are embedded inside the concrete columns and end plates, and are usually composed of steel bars and steel rings. They are designed to improve the overall structural strength of the concrete columns through the high strength characteristics of the steel reinforcement materials, preventing damage to the pipe piles during stress.

[0004] However, existing concrete pipe piles have the following drawbacks in practical applications: First, in terms of the structural design of the reinforcing frame, since it consists only of steel columns and steel rings, the connection strength between the two is limited. When the pipe pile is subjected to external impact, the steel columns and steel rings are prone to separation. This directly weakens the reinforcing effect of the reinforcing frame on the concrete column, resulting in a decrease in the structural stability of the concrete column and making it difficult to effectively cope with the load under complex working conditions. Second, the outer surface of existing concrete pipe piles is mostly a smooth plane. When used in soft foundation scenarios, this smooth surface results in less friction between the pipe pile and the surrounding soft soil, i.e., insufficient lateral friction resistance. This can cause the concrete pipe pile to tilt when subjected to upper loads or external forces, seriously affecting the stability of the foundation and the safety of the project.

[0005] Therefore, it is essential to invent a concrete pipe pile for soft foundations. Utility Model Content

[0006] To address the above problems, this utility model proposes a concrete pipe pile for soft foundations, and the technical solution used is as follows: A concrete pipe pile for soft foundation includes a concrete column, end plates, reinforcing frames, anti-deviation plates, and an inner cavity. Both ends of the concrete column are integrally formed with end plates, wherein the diameter of the end plates is larger than the diameter of the concrete column. Reinforcing frames are fixed inside the concrete column and the end plates, and an inner cavity is formed through the interior of both the concrete column and the end plates. Several anti-deviation plates are uniformly fixed on the concrete column, and the diameter of the anti-deviation plates is larger than the diameter of the concrete column.

[0007] Furthermore, the reinforcing frame includes flanges, reinforcing bars, and reinforcing rings. Two flanges are provided, each fixed to the side of a corresponding end plate. Several reinforcing bars are uniformly fixed between the two flanges by welding. Several reinforcing rings are fixed to the outer side of the reinforcing bars by welding. Both the reinforcing bars and the reinforcing rings are fixed inside the concrete column. This arrangement not only strengthens the concrete column and improves its structural strength but also compresses the concrete column and the end plate.

[0008] Furthermore, the reinforcing frame also includes a fastening frame, of which there are several fastening frames, and the fastening frames are in the shape of a "U". The fastening frames are arranged around the corresponding steel bar columns, and both ends of the fastening frames are fixed to the corresponding steel bar rings by welding. This arrangement can strengthen the connection strength between the steel bar columns and the steel bar rings, thereby preventing the steel bar columns and steel bar rings from separating when subjected to external forces.

[0009] Furthermore, the anti-deflection plate includes a plate body and a first through hole. The plate body is fixed to the concrete column, and the diameter of the plate body is larger than the diameter of the concrete column. Several first through holes are opened through the interior of the plate body, and corresponding steel bars are fixed inside each of the first through holes. This arrangement can improve the side friction resistance of the concrete pipe pile and enhance the vertical and pull-out bearing capacity.

[0010] Furthermore, the anti-deviation plate also includes a second through hole, which is formed through the plate body, and several second through holes are provided; the second through hole passes through a part of the concrete column structure, which can prevent the concrete column from breaking at the anti-deviation plate position.

[0011] Compared with the prior art, the present invention has the following beneficial effects: The reinforcing frame of this utility model strengthens the concrete column by combining the steel column and the steel ring, thereby improving the structural strength of the concrete column. Secondly, the combination of the steel column and the flange allows for the compression of the concrete column and the end plate. Furthermore, the fastening frame strengthens the connection between the steel column and the steel ring, thus preventing the steel column and the steel ring from separating when subjected to external forces.

[0012] The anti-deflection plate of this utility model, because the diameter of the plate is larger than the diameter of the concrete column, can increase the side friction resistance of the concrete pipe pile, improve the vertical and pull-out bearing capacity, and at the same time prevent the concrete pipe pile from tilting when used in soft foundation scenarios.

[0021] Please see Figures 1 to 4As shown, this utility model is a concrete pipe pile for soft foundation, including a concrete column 1, an end plate 2, a reinforcing frame 3, an anti-deviation plate 4, and an inner cavity 5.

The reinforcing frame 3 is fixed inside both the concrete column 1 and the end plate 2, and the inner cavity 5 is opened through both the concrete column 1 and the end plate 2. Several anti-deviation plates 4 are uniformly fixed on the concrete column 1, and the diameter of the anti-deviation plate 4 is larger than the diameter of the concrete column 1.

[0022] Specifically, the reinforcing frame 3 includes a flange 31, reinforcing bars 32, and reinforcing rings 33. Two flanges 31 are provided, and the flanges 31 are fixed to the sides of the corresponding end plates 2. Several reinforcing bars 32 are uniformly fixed between the two flanges 31 by welding. Several reinforcing rings 33 are fixed to the outer side of the reinforcing bars 32 by welding. The reinforcing bars 32 and the reinforcing rings 33 are both fixed inside the concrete column 1. This arrangement can strengthen the concrete column 1 and improve its structural strength. Furthermore, the cooperation between the reinforcing bars 32 and the flanges 31 can compress the concrete column 1 and the end plates 2.

[0023] Specifically, the reinforcing frame 3 also includes a fastening frame 34. Several fastening frames 34 are provided, and the shape of the fastening frame 34 is "U". The fastening frames 34 are respectively arranged around the corresponding steel column 32, and both ends of the fastening frame 34 are fixed to the corresponding steel ring 33 by welding.

Several first through holes 42 are opened through the inside of the plate body 41, and corresponding steel bars 32 are fixed inside each of the first through holes 42. When in use, since the diameter of the plate body 41 is larger than the diameter of the concrete column 1, it can increase the side friction resistance of the concrete pipe pile and improve the vertical and pull-out bearing capacity.

[0025] Specifically, the anti-deviation plate 4 also includes a second through hole 43, which is opened through the plate body 41, and there are several second through holes 43; a part of the concrete column 1 passes through the inside of the second through hole 43.
