Description

Technical Field

[0001] The utility model relates to the technical field of prestressed concrete piles, in particular to a prestressed concrete wave pile. Background Art

[0002] Concrete wave piles are a type of ecological slope protection product. They are prestressed concrete components with a semicircular cross-section. The concrete strength is not less than C80, and the main reinforcement is prestressed concrete steel rods. They are produced using the pre-tensioning process, which can delay the cracking of concrete and provide higher bending bearing capacity. High-performance composite materials independently developed are added to the concrete, and the concrete formula and curing process are optimized. The piles are formed after centrifugal molding and high-temperature curing, which greatly improves the durability of the pile body concrete. It is a green, energy-saving, environmentally friendly and durable product. It changes the shortcomings of traditional water conservancy projects such as high cost and unstable molding quality of materials used. In addition, when wave piles are used as bank and slope protection in water conservancy projects, in order to improve the sinking effect of wave piles and the bearing capacity after sinking, multiple wave piles are usually spliced ​​up and down to increase the length of the pile body.

[0003] For example, a wave pile with a ribbed structure disclosed in the patent with publication number CN218540590U includes a plurality of interconnected unit piles, each of which is provided with steel bars, and concrete is poured along the extension direction of the steel bars so that the unit pile has a pile body in the shape of a semi-cylindrical groove, and rib structures are arranged at intervals on the inner and outer peripheral surfaces of the semi-cylindrical groove-shaped pile body, and the rib structures are annular protrusions; a connecting tongue and groove is arranged on the side of the pile body of each unit pile, so as to be used for connecting two adjacent unit piles to form a wave pile. The use of a ribbed structure in the pile body can increase the contact area between the pile side and the soil, increase the lateral friction between the pile body and the soil, and realize that a pile with a smaller diameter can provide the same bearing capacity as a pile with a larger diameter, and further save materials and reduce production costs.

[0004] However, the wave piles in the above technology still have the following problems:

[0005] Although the contact area between the pile body and the soil is increased by the rib structure, the rib structure will cause the pile body to contact with the soil layer during the pile sinking operation, which will cause a great obstacle to the pile sinking operation and make the pile sinking more difficult. Utility Model Content

[0008] Furthermore, the outer wall of the annular splicing plate is arranged to fit the outer wall of the wave pile body.

[0009] Furthermore, a plurality of bolt holes are provided on the outer wall of the annular splicing plate, and the other ends of the plurality of bolt holes penetrate the splicing groove and the outer wall of the other side of the annular splicing plate.

[0011] Furthermore, the same end of the mounting plate and the connecting plate is flush with the side of the wave pile body close to the annular earth-inserting plate, and the other end of the mounting plate and the connecting plate is flush with the side of the annular splicing plate away from the wave pile body 1.

[0012] Furthermore, a T-shaped connecting groove is provided on one side of the mounting plate away from the connecting plate, and both upper and lower ends of the T-shaped connecting groove are through-opened. A T-shaped connecting strip is fixedly connected to one side of the connecting plate away from the mounting plate, and the T-shaped connecting strip is matched with the T-shaped connecting groove.

[0019] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0020] See also Figure 1 - Figure 3 A prestressed concrete wave pile comprises a wave pile body 1, a ring-shaped earth plug plate 2 is fixedly connected to the bottom of the wave pile body 1, and the corners of the ring-shaped earth plug plate 2 away from the wave pile body 1 are provided with chamfers, and matching mounting plates 3 and connecting plates 4 are fixedly connected to both sides of the wave pile body 1, and the mounting plates 3 and connecting plates 4 are respectively located on the inward sides of the two ends of the wave pile body 1, and an annular splicing plate 5 is fixedly connected to the end of the wave pile body 1 away from the annular earth plug plate 2, and a splicing groove 501 matching the annular earth plug plate 2 is opened on the side of the annular splicing plate 5 away from the wave pile body 1.

[0021] like Figure 1 - Figure 3 As shown, a prestressed concrete wave pile in the utility model is similar to the existing prestressed concrete wave pile structure, such as a wave pile with a rib structure disclosed in the patent with publication number CN218540590U. The main improvement of the utility model is that the wave pile body 1 can be more easily inserted into the soil layer during the pile sinking operation, thereby improving the pile sinking efficiency. Figures 1 to 3 As shown, when the prestressed concrete wave pile in the utility model is in use, the annular soil insertion plate 2 of the wave pile body 1 is inserted into the soil layer. Through the chamfer design below the annular soil insertion plate 2, the soil layer can be separated more easily, thereby making it easier for the wave pile body 1 to sink the pile. At the same time, when it is necessary to increase the overall height of the wave pile body 1, the annular soil insertion plate 2 of the upper wave pile body 1 can be inserted into the splicing groove 501 of the annular splicing plate 5 on the top of the lower wave pile body 1. Therefore, while completing the connection between the upper and lower wave pile bodies 1, the upper and lower wave pile bodies 1 are aligned with each other, thereby improving the convenience of splicing the wave pile body 1. At the same time, the wave pile bodies 1 on both sides can also be spliced ​​and installed through the mounting plate 3 and the connecting plate 4.

[0022] like Figure 1 - Figure 3As shown, the outer wall of the annular splicing plate 5 is arranged to fit the outer wall of the wave pile body 1. The outer wall of the annular splicing plate 5 is designed to fit the outer wall of the wave pile body 1, so that when the wave pile body 1 is inserted into the soil layer and the pile sinking operation is performed, the annular splicing plate 5 will not produce compression obstruction with the soil layer, so that the pile sinking operation can be carried out more smoothly.

[0023] like Figure 1 - Figure 3 As shown, the outer wall of the annular splicing plate 5 is provided with a plurality of bolt holes 502, and the other ends of the plurality of bolt holes 502 all penetrate the splicing groove 501 and the outer wall of the other side of the annular splicing plate 5, and the outer wall of the annular plug plate 2 is provided with a connection hole 201 matching the plurality of bolt holes 502, and the plurality of bolt holes 502 are connected with a splicing bolt 6, and the threaded rods of the plurality of splicing bolts 6 respectively penetrate the plurality of bolt holes 502 and the corresponding connection holes 201, and are threadedly connected with the bolt holes 502. After the upper and lower wave pile bodies 1 are spliced ​​and installed mutually through the annular plug plate 2 and the annular splicing plate 5, the splicing bolt 6 is passed through the bolt hole 502 on one side, the connection hole 201 and the bolt hole 502 connected on the other side in sequence, and is threadedly tightened with the bolt hole 502, so that the annular plug plate 2 is connected and fixed with the annular splicing plate 5 below, so that the upper and lower wave pile bodies 1 form a fixed whole, and the connection firmness between the upper and lower wave pile bodies 1 is further improved.

[0024] like Figure 1 - Figure 3 As shown, the bolt cap of the splicing bolt 6 is located on the outward side of the annular splicing plate 5 and abuts against the outward side of the annular splicing plate 5. Inserting the splicing bolt 6 from the outer bolt hole 502 to the inner bolt hole 502 and making the bolt cap abut against the outer side of the annular splicing plate 5 can make it more convenient to tighten the splicing bolt 6, avoid the small space inside the wave pile body 1, and cause obstacles to tightening the splicing bolt 6, and make it more convenient to install the splicing bolt 6.

[0025] like Figure 1 - Figure 3 As shown, the same end of the mounting plate 3 and the connecting plate 4 is flush with the side of the wave pile body 1 close to the annular earth plugging plate 2, and the other ends of the mounting plate 3 and the connecting plate 4 are flush with the side of the annular splicing plate 5 away from the wave pile body 1. The upper and lower ends of the mounting plate 3 and the connecting plate 4 are designed to be flush with the wave pile body 1 and the annular splicing plate 5, respectively, so that after the upper and lower wave pile bodies 1 are spliced ​​together, the upper and lower groups of mounting plates 3 and connecting plates 4 can be connected to each other, so that there is no cavity between the two upper and lower spliced ​​wave pile bodies 1, and the connection is tighter.

[0026] like Figure 1 - Figure 3As shown, a T-shaped connecting groove 301 is provided on the side of the mounting plate 3 away from the connecting plate 4, and both upper and lower ends of the T-shaped connecting groove 301 are through-opened, and a T-shaped connecting strip 7 is fixedly connected to the side of the connecting plate 4 away from the mounting plate 3, and the T-shaped connecting strip 7 is matched with the T-shaped connecting groove 301. When the wave pile body 1 needs to be spliced ​​horizontally, the side with the T-shaped connecting strip 7 can be inserted into the T-shaped connecting groove 301 on another wave pile body 1, so that the mounting plates 3 and the connecting plates 4 of the two wave pile bodies 1 are mutually connected and fixed through the T-shaped connecting groove 301 and the T-shaped connecting strip 7, thereby completing the installation, splicing and fixing between multiple wave pile bodies 1 horizontally.

[0027] Although the embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that many changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention.
