[0002] When the bridge piles are placed in the soil, if the soil contains a high moisture content, the compactness of the soil will decrease, which will make the bridge piles unable to achieve sufficient stability. Because the pile foundation needs to transfer the load of the superstructure to the solid soil or rock deep underground, if the soil around the pile foundation is too loose and cannot effectively transfer the load, it will seriously affect the overall stability and service life of the bridge. In addition, the loose and water-rich soil environment may also cause the pile foundation to sink and tilt, further weakening the structural integrity of the bridge and increasing potential safety risks.

[0020] The following will clearly and completely describe the concept, specific structure and technical effects of the utility model in combination with the embodiments and drawings, so as to fully understand the purpose, characteristics and effects of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of them.

[0021] Reference Figures 1 to 4 A bridge pile structure includes a pile body 1, a pressure block and a reinforced concrete layer 3; the pile body 1 is configured to be cylindrical, so that a vertically extending channel is formed in the cylindrical pile body 1, the pressure block is arranged in the channel, the pressure block is used to press the soil downward, the pressure block is fixedly connected to the pile body 1, the height of the pressure block is higher than the lower end of the pile body 1, the reinforced concrete layer 3 is filled in the channel, and the reinforced concrete layer 3 is arranged above the pressure block.

[0022] When it is necessary to fix the pile body 1 into the soil, the construction personnel can first insert the lower end of the pile body 1 into the soil so that the pile body 1 is arranged vertically. Then the construction personnel can clean the soil in the channel on the pile body 1. On the one hand, the soil rich in water can be cleaned away, and on the other hand, the contact area between the pile body 1 and the soil can be reduced, thereby reducing the friction so that the pile body 1 can be inserted to a deeper depth. After the pile body 1 is inserted to a deeper depth, the soil in the pile body 1 is compacted to squeeze out the moisture in the soil and draw out the moisture. Then a pressing block is set in the channel to use the pressing block to press the soil in the channel downward to ensure that the soil is flat and firm, so as to reduce the amount of moisture that can enter the soil; in addition, the pressing block is fixedly connected to the pile body 1, which can improve the strength of the pile body 1 to a certain extent. The channel is filled with a reinforced concrete layer 3, and the structural strength in the pile body 1 is improved by setting the reinforced concrete layer 3. In addition, the reinforced concrete layer 3 can be connected with the pressing block and the pile body 1, thereby further improving the structural strength of the pile body 1.

[0023] The bridge pile structure designed by the present technical solution adopts a cylindrical design in which the pile body 1 forms a vertically extending channel inside. This design is intended to facilitate soil cleaning and subsequent filling of the reinforced concrete layer 3 during construction, and also provides space for the setting of the pressing block. The pressing block is set in the channel and fixed on the pile body 1, and its height is higher than the lower end of the pile body 1. The main function of the pressing block is to compact the soil downward to ensure that the soil is flat and firm and reduce the possibility of moisture penetrating into the soil. In addition, the fixed connection between the pressing block and the pile body 1 can also improve the strength of the pile body 1 to a certain extent. Filling the reinforced concrete layer 3 in the channel can, on the one hand, increase the structural strength inside the pile body 1 and improve the overall stability; on the other hand, the connection between the reinforced concrete layer 3 and the pressing block and the pile body 1 can further enhance the structural strength of the pile body 1.

[0024] The design of the cylindrical pile body 1 facilitates the cleaning of water-rich soil and the filling of the reinforced concrete layer 3 during the construction process. The arrangement of the pressing block and the reinforced concrete layer 3 can effectively compact the soil and reduce the possibility of water penetrating into the soil, thereby enhancing the stability of the pile. At the same time, the filling of the reinforced concrete layer 3 also increases the structural strength inside the pile body 1. The fixed connection between the pressing block and the pile body 1 and the connection between the reinforced concrete layer 3, the pressing block and the pile body 1 can improve the strength of the pile body 1 to a certain extent, making it more solid and durable.
