Abstract
Description
Technical Field
[0001] This utility model relates to the field of water conservancy engineering technology, and in particular to a water conservancy engineering foundation pile. Background Technology
[0002] In the field of water conservancy engineering, foundation piles, as an important foundation structure, undertake the key tasks of supporting hydraulic structures, transferring loads, and ensuring the stability of the project. With the continuous expansion of the scale of water conservancy construction and the increasing technical requirements, higher requirements have been placed on the performance and quality of foundation piles. Traditional water conservancy engineering foundation piles are mostly made of wood or concrete. Wood piles were widely used in early water conservancy projects, but they have problems such as poor durability and low strength. They are easily eroded by water and damaged by organisms, and have a limited service life. Although concrete piles have high strength and good stability, they may also crack and settle unevenly in complex water environments, such as water scouring and riverbed changes.
[0003] The existing foundation piles have an excessively large contact area between their outer wall and the silt during installation. This means that the foundation piles will encounter greater resistance when inserted into the silt. This not only requires more powerful construction equipment to overcome the resistance, increasing equipment investment costs, but may also prolong construction time and affect project progress. At the same time, when encountering hard silt layers or complex geological conditions, it may be difficult for the foundation piles to be inserted into the predetermined position smoothly, increasing the uncertainty and difficulty of construction.
[0004] Therefore, there is an urgent need to provide a type of hydraulic engineering foundation pile to solve the above problems. Utility Model Content
[0005] The technical problem to be solved by this utility model is to overcome the shortcomings of the prior art and provide a foundation pile for water conservancy projects.
[0006] To solve the above-mentioned technical problems, the present invention provides a hydraulic engineering foundation pile, including a body, an inlay block fixedly connected to one side of the outer wall of the body, an inlay groove opened on the other side of the outer wall of the body, a conical block provided at the bottom of the body, multiple drag-reducing grooves opened at both the front and rear ends of the outer walls of the body and the conical block, and a flushing component provided inside the body.
[0007] The present invention is further configured such that: the main body is made of reinforced concrete, and the conical block is made of alloy steel.
[0008] Through the above technical solutions, reinforced concrete has high compressive strength and can withstand the huge pressure from the superstructure, ensuring that the foundation piles will not deform or be damaged during long-term use. At the same time, alloy steel has good corrosion resistance and can resist the erosion of water, chemicals in the soil and other corrosive media, thereby extending the service life of the cone blocks.
[0009] The present invention is further configured such that the multiple drag-reducing grooves are all of equal size, and the distance between any two drag-reducing grooves is also equal.
[0010] The above technical solutions can reduce the friction between the pile and the surrounding soil. When the friction-reducing grooves are of equal size and spacing, the friction force on the pile is more evenly distributed. This allows the pile to transmit the force to the ground more stably when bearing the load from the superstructure, reducing the risk of pile deformation or damage caused by excessive local friction.
[0011] The present invention is further configured such that: the flushing assembly includes a plurality of first pipes opened inside the main body, a connector is installed on one side of the inner wall of each of the plurality of first pipes, a plurality of second pipes are opened at the bottom of the inner wall of each of the plurality of first pipes, a plurality of third pipes are opened at both the front and rear ends of the inner wall of each of the plurality of second pipes, a water outlet plate is fixedly connected to one end of the inner wall of each of the plurality of third pipes, and a reinforcing steel pipe is slidably connected to the inner wall of each of the plurality of second pipes.
[0012] The above technical solution involves first connecting the high-pressure water pipe to the outer wall of the corresponding connector, then opening the high-pressure water pipe in sequence according to the order of soil entry to inject water into the corresponding first pipe. At the same time, the clean water in the first pipe will be transported to the second pipe, and then the clean water in the second pipe will be transported to the corresponding third pipe. Subsequently, the clean water in the third pipe will be transported out through the water outlet plate to deliver the high-pressure water, thereby achieving the effect of flushing silt and reducing resistance.
[0013] The present invention is further configured such that: each of the inner walls of the plurality of first pipes is provided with a threaded line, and the plurality of connectors are threadedly connected to the corresponding inner walls of the first pipes.
[0014] The above technical solutions can provide a very tight connection, effectively preventing water or other fluids from leaking at the pipe connection. At the same time, they can withstand greater tensile and shear forces, and are not easy to loosen or fall off, thereby improving the connection strength of the entire pipeline system.
[0015] The present invention is further configured such that the inner walls of the plurality of second pipes are tightly fitted to the outer walls of the corresponding reinforced steel pipes.
[0016] Through the above technical solution, the close fit allows the second pipeline and the reinforcing steel pipe to jointly withstand the external pressure and the force of the internal fluid. The reinforcing steel pipe has high strength and rigidity. At the same time, the reinforcing steel pipe can also limit the radial expansion and axial bending of the second pipeline, maintain the stability of the pipeline shape, and thus ensure the normal operation of the pipeline system.
[0017] The present invention is further configured such that the lateral distance between every two second pipes and water outlet plates is equal.
[0018] The above technical solutions can make the forces between each second pipe and the water outlet plate more balanced. Equal lateral distances can make the forces evenly distributed, improving the stability and reliability of the entire structure.
[0019] The beneficial effects of this utility model are as follows:
[0020] 1. By setting up a flushing component, this utility model can effectively reduce the resistance of silt to the foundation pile, enabling the foundation pile to sink into the ground more quickly. This will significantly shorten the installation time, improve construction efficiency, and save a lot of time and costs.
[0021] 2. By setting a drag-reducing groove, this utility model can reduce the contact area between the foundation pile and the surrounding soil, thereby reducing the lateral pressure of the soil on the foundation pile, improving the bearing capacity and stability of the foundation pile, reducing the risk of damage caused by external forces, and also reducing the maintenance cost of water conservancy projects.

[0028] The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings, so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby making a clearer and more definite definition of the scope of protection of the present invention.
[0029] Please see Figure 1 - Figure 5 A hydraulic engineering foundation pile includes a body 1, an inlay block 2 fixedly connected to one side of the outer wall of the body 1, an inlay groove 3 formed on the other side of the outer wall of the body 1, and a conical block 4 set at the bottom of the body 1. The body 1 is made of reinforced concrete, and the conical block 4 is made of alloy steel. Reinforced concrete has high compressive strength and can withstand the huge pressure from the superstructure, ensuring that the foundation pile will not deform or be damaged during long-term use. At the same time, alloy steel has good corrosion resistance and can resist water, chemicals in the soil, and other substances. The corrosive medium erosion extends the service life of the cone block 4. Multiple drag-reducing grooves 5 are provided at both ends of the outer wall of the body 1 and the cone block 4. The multiple drag-reducing grooves 5 are all of equal size, and the distance between every two drag-reducing grooves 5 is also equal. This can reduce the friction between the pile body and the surrounding soil. When the drag-reducing grooves 5 are of equal size and equal spacing, the friction force on the pile body is more evenly distributed. This allows the pile to transmit the force to the ground more stably when bearing the load from the superstructure, reducing the risk of pile deformation or damage caused by excessive local friction.
[0030] like Figure 2 , Figure 3 , Figure 4 and Figure 5As shown, a flushing assembly 6 is provided inside the main body 1. The flushing assembly 6 includes multiple first pipes 601 opened inside the main body 1. A connector 603 is installed on one side of the inner wall of each of the multiple first pipes 601. Multiple second pipes 604 are opened at the bottom of the inner wall of each of the multiple first pipes 601. Multiple third pipes 605 are opened at both ends of the inner wall of each of the multiple second pipes 604. A water outlet plate 606 is fixedly connected to one end of the inner wall of each of the multiple third pipes 605. A reinforcing steel pipe 607 is slidably connected to the inner wall of each of the multiple second pipes 604. First, connect the high-pressure water pipe to the outer wall of the corresponding connector 603. Then, according to the order of soil entry, open the high-pressure water pipe to inject water into the corresponding first pipe 601. At the same time, the clean water in the first pipe 601 will be transported to the second pipe 604, and then the clean water in the second pipe 604 will be transported to the corresponding third pipe 605. Subsequently, the clean water in the third pipe 605 will be transported out through the water outlet plate 606, thereby achieving the effect of flushing silt and reducing resistance. Multiple first pipes 601 have [equipment / details] on one side of their inner walls. The system has a threaded wire 602, and multiple connectors 603 are threadedly connected to the inner wall of the corresponding first pipe 601. This provides a very tight connection, effectively preventing water or other fluids from leaking at the pipe connection. At the same time, it can withstand large tensile and shear forces, and is not easy to loosen or fall off, thereby improving the connection strength of the entire pipeline system. The inner walls of multiple second pipes 604 are tightly fitted to the outer walls of the corresponding reinforcing steel pipes 607. This tight fit allows the second pipes 604 and the reinforcing steel pipes 607 to jointly withstand the external pressure and the force of the internal fluid. The reinforcing steel pipes 607 have high strength and rigidity. At the same time, the reinforcing steel pipes 607 can also limit the radial expansion and axial bending of the second pipes 604, maintaining the stability of the pipe shape, thereby ensuring the normal operation of the pipeline system. The lateral distance between every two second pipes 604 and the outlet plate 606 is equal, which makes the force between each second pipe 604 and the outlet plate 606 more balanced. Moreover, the equal lateral distance can make the force evenly distributed, improving the stability and reliability of the entire structure.
[0031] In use, the high-pressure water pipe is first threaded onto the outer wall of the corresponding connector 603. Then, water is injected into the corresponding first pipe 601 according to the order of soil entry. At the same time, the clean water in the first pipe 601 is transported to the second pipe 604, and then the clean water in the second pipe 604 is transported to the corresponding third pipe 605. Subsequently, the clean water in the third pipe 605 is transported out through the water outlet plate 606, thereby achieving the effect of flushing silt and reducing resistance.
