If the pile bodies are arranged too closely, friction between the pile bodies may occur easily.

[0004] Therefore, in view of this, research and improvement are carried out to the existing deficiencies, and a drainage hollow pile for use in civil engineering is proposed. Utility Model Content

[0005] The purpose of the utility model is to provide a drainage hollow pile used in civil engineering to solve the problems raised in the above background technology.

[0006] To achieve the above object, the utility model provides the following technical solution: a drainage hollow pile for civil engineering, comprising: a column, characterized in that a column cone is provided at the bottom end of the column, a column bottom is provided at the bottom end of the column cone, and an auxiliary structure is fixedly provided on the outer side of the column cone;

[0007] An inner hollow groove is vertically opened on the inner side of the column, and a drainage structure is vertically arranged inside the inner hollow groove.

[0008] Furthermore, the auxiliary structure includes positioning ribs and soil-breaking blocks. The outer side of the column cone is provided with positioning ribs downward, and the outer side of the positioning ribs is sleeved with soil-breaking blocks. The positioning ribs and the column cone are fixedly connected to prevent the positioning ribs from shifting.

[0009] Furthermore, the soil-breaking block is made of concrete material, which is convenient for providing the soil-breaking block with hardness.

[0010] Furthermore, the length of the soil-breaking block can be designed by the staff according to the specific contact area between the foundation and the bottom of the column, so as to increase the contact area between the bottom of the column and the ground soil by extending the length of the soil-breaking block.

[0011] Furthermore, the diameter of the inner hollow groove is smaller than the cross-sectional length of the column, so that a large amount of rainwater can enter the inner hollow groove.

[0012] Furthermore, the drainage structure includes a water collecting pipe and a water guiding pipe. A water collecting pipe is vertically arranged on the inner side of the column, and a water guiding pipe is arranged at the bottom end of the water collecting pipe. The shape of the water guiding pipe is L-shaped, so that rainwater can be easily discharged from the water guiding pipe through the water collecting pipe.

[0013] Furthermore, the water collecting pipe is fixedly connected to the column to prevent the water collecting pipe from being displaced when irrigated by rainwater.

[0014] Compared with the prior art, the beneficial effects of the utility model are:

[0015] 1. When the utility model drives the column cone and the column bottom to be installed toward the foundation through the column body, the positioning ribs on the outside of the column cone follow the column cone into the foundation, and at the same time, the soil-breaking blocks on the outside of the positioning ribs are used to scrape the waste soil stuck to the outside of the column cone, so that after the column cone enters the foundation, the positioning ribs and the soil-breaking blocks can help the column bottom and the column cone to remove the surrounding waste soil, which can effectively simplify the construction process and improve construction efficiency.

[0016] 2. The utility model allows rainwater to enter the inner hollow groove, and the water collecting pipe is installed inside the inner hollow groove. At the same time, the water collecting pipe collects the introduced rainwater, and the water guide pipe guides the rainwater inside the water collecting pipe to the outside of the column. This can prevent excessive water accumulation inside the inner hollow groove due to excessive rainwater. By integrating the drainage function into the pile structure, it not only solves the water accumulation problem faced by traditional hollow piles, but also improves the durability and safety of the overall structure.

[0026] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0027] like Figure 1-8 As shown, the utility model provides a technical solution: a drainage hollow pile used in civil engineering, comprising: a column body 1, a column cone 4 is arranged at the bottom end of the column body 1, a column bottom 3 is arranged at the bottom end of the column cone 4, an auxiliary structure 2 is fixedly arranged on the outer side of the column cone 4, an inner hollow groove 6 is vertically opened on the inner side of the column body 1, and a drainage structure 5 is vertically arranged inside the inner hollow groove 6.

[0028] The auxiliary structure 2 includes positioning ribs 201 and soil-breaking blocks 202. The outer side of the column cone 4 is provided with positioning ribs 201 downwardly, and the outer side of the positioning ribs 201 is sleeved with soil-breaking blocks 202. Through the structural combination of the positioning ribs 201 and the soil-breaking blocks 202, the positioning and soil-breaking functions can be achieved at the same time, thereby simplifying the construction process and improving construction efficiency. The positioning ribs 201 and the column cone 4 are fixedly connected to prevent the positioning ribs 201 from shifting and improve the stability of the pile foundation.

[0029] The soil-breaking block 202 is made of concrete material, which is convenient for providing the hardness of the soil-breaking block 202 so that the soil-breaking block 202 can achieve the function of removing waste soil adhering to the outer side of the column cone 4.

[0030] The length of the soil-breaking block 202 can be designed by the staff according to the specific contact area between the foundation and the column bottom 3, so as to increase the contact area between the column bottom 3 and the ground soil by extending the length of the soil-breaking block 202 to adapt to different foundation conditions.

[0031] The diameter of the inner hollow groove 6 is smaller than the cross-sectional length of the column 1, so that a large amount of rainwater can enter the inner hollow groove 6, which is beneficial to controlling surface runoff and reducing the impact on the surrounding environment.

[0032] The drainage structure 5 includes a water collecting pipe 501 and a water guiding pipe 502. The water collecting pipe 501 is vertically penetrated through the inner side of the column 1, and the water guiding pipe 502 is arranged at the bottom of the water collecting pipe 501. The water guiding pipe is L-shaped, which is convenient for rainwater to be discharged from the water guiding pipe 502 through the water collecting pipe 501, thereby realizing automatic drainage, effectively preventing excessive water accumulation in the inner hollow groove 6, reducing the accumulation of water inside the pile structure, and extending the service life.

[0033] The water collecting pipe 501 is fixedly connected to the column 1 to prevent the water collecting pipe 501 from being displaced when irrigated by rainwater, thereby improving the stability of the pile structure.

[0034] Working principle: When using the utility model, first place the column body 1, the column bottom 3 and the column cone 4 inside the foundation. When the column cone 4 contacts the ground, the column cone 4 drives the positioning ribs 201 and the soil-breaking blocks 202 to embed into the soil. At the same time, the soil-breaking blocks 202 outside the column cone 4 separate the excess soil from the column bottom 3, so that when the column bottom 3 contacts the ground, the positioning ribs 201 increase the contact area between the column bottom 3 and the ground soil. At the same time, when there is too much rain outside, the water collecting pipe 501 inside the inner hollow groove 6 collects the excess rainwater, and then discharges the rainwater introduced by the water collecting pipe 501 through the water guide pipe 502.

[0035] The embodiments of the present invention are provided for the purpose of illustration and description, and are not intended to be exhaustive or to limit the present invention to the disclosed forms. Many modifications and variations will be apparent to those of ordinary skill in the art. The embodiments are selected and described to better illustrate the principles and practical applications of the present invention, and to enable those of ordinary skill in the art to understand the present invention and thereby design various embodiments with various modifications suitable for specific uses.
