Description

Technical Field

[0001] This utility model relates to the technical field of pile foundation engineering for various building structural systems, and in particular to a corrugated pile and spliced ​​wall. Background Technology

[0002] U-shaped sheet piles are required for retaining structures during the construction of various buildings, such as large underground structures, slopes, tunnels, port and wharf embankments, and riverbank protection. In existing technologies, some U-shaped sheet piles are semi-circular rings, which are then spliced ​​together to create a wave-shaped spliced ​​wall. An example of an existing U-shaped sheet pile is the Chinese utility model patent CN202120640507.9 (authorization announcement number CN215482879U), entitled "A Prestressed Concrete Wave Pile." This wave pile consists of several unit piles, each of which is a semi-circular ring. Each unit pile has splicing grooves on both sides of its ring. The splicing grooves of adjacent unit piles fit together to form the wave pile.

[0003] Although the aforementioned unit piles can form wavy piles through splicing slots, the splicing slots are located at both ends of the semicircular ring, facing forward and backward. This means that the splicing slots of two adjacent unit piles overlap to form a wavy pile. The overlapping splicing slots make the splicing of the unit piles unreliable, easily causing misalignment. This results in insufficient structural strength and bending resistance of the wavy spliced ​​wall, thus affecting its performance in engineering projects. This splicing is theoretically an overlap; in actual construction, many piles fail to interlock properly, leading to significant detachment and difficulties in acceptance. Furthermore, the splicing slot design of the aforementioned unit piles can only overlap when splicing into wavy spliced ​​walls; this type of splicing slot cannot be used to splice into other shapes (such as M-shaped spliced ​​walls), limiting the application scenarios of this unit pile. Therefore, further improvements to sheet piles are needed. Summary of the Invention

[0004] The first technical problem to be solved by this utility model is to provide a waveform pile with a simple structure and reasonable stress distribution, in view of the above-mentioned existing technology.

[0005] The technical solution adopted by this utility model to solve the first technical problem is as follows: the corrugated pile includes a pile body, the pile body includes a front end face, a rear end face, and a connecting surface connecting the ends of the front end face and the rear end face, the connecting surface is a plane, characterized in that: the front end face and the rear end face are arc-shaped surfaces that bulge forward, the rear end face forms an arc-shaped groove extending along the length direction of the pile body, and the outer sides of the left and right ends of the front end face are respectively provided with concave stop and convex stop extending along the length direction of the pile body, the convex stop and the concave stop are correspondingly provided.

[0006] As one option for concave and convex stops, preferably, the concave stop has two adjacent inclined surfaces, the connection of which is set at an obtuse angle. The two outer end faces of the convex stop correspond to the two inclined surfaces of the concave stop. A clearance notch is provided at the connection between the convex stop and the front end face, and this clearance notch corresponds to the connection between the concave stop and the front end face. The convex and concave stops are correspondingly arranged, with a clearance notch formed at the connection between the convex stop and the front end face, and an arc-shaped tip formed at the connection between the concave stop and the front end face. This tip matches the clearance notch, allowing the tip of the concave stop at the connection between the front end face of the pile body to be inserted into the clearance notch of an adjacent pile body.

[0007] To enhance the strength of the pile head, preferably, the top of the arc-shaped groove is provided with a thickened section. The top wall of the thickened section is flush with the top wall of the pile body, and the bottom surface of the thickened section is a slope that gradually slopes downward from the outside to the inside. The thickened section increases the cross-sectional area at the pile head position, thus increasing the strength of the pile head. During pile driving, the increased contact area between the pile hammer and the pile head disperses the impact force of the pile hammer, and the increased strength of the pile head, combined with these two factors, effectively ensures that the pile head is not easily cracked or damaged during pile driving, ensuring the aesthetics of the retaining wall and the structural performance of the concrete pile. Compared with adding metal end plates, the thickened section is less expensive and requires no additional fixing steps; only adaptive adjustments to the sheet pile mold are needed, simplifying the process.

[0008] To improve the splicing effect of corrugated piles, preferably, multiple guide plates are provided on one connecting surface of the pile body. One end of each guide plate is fixed to the connecting surface by pre-embedded steel bars, and the other end of the guide plate protrudes from the pile body. The connecting surface is planar. During pile manufacturing, steel bars are pre-embedded at the corresponding positions of the guide plates, and then the guide plates are welded to the pre-embedded steel bars, thereby installing the guide plates on the pile body. When two adjacent corrugated piles are spliced, the guide plate protruding from the pile body of one corrugated pile abuts against the connecting surface of the adjacent corrugated pile, thus improving the splicing effect of the two corrugated piles. The corrugated piles can be spliced ​​together with consistent orientation and tightness to form a splicing wall.

[0009] As another possible method for connecting the guide plate to the pile body, preferably, it also includes multiple guide plates for guidance. One end of each guide plate has a mounting hole, and the connecting surface has a connecting hole corresponding to the mounting hole. One end of the guide plate is fixed to the connecting surface by means of a sleeve passing through the mounting hole and the connecting hole, while the other end of the guide plate protrudes from the pile body. The connecting surfaces of the guide plate and the pile body are connected by a sleeve, that is, the sleeve passes through the mounting hole and the connecting hole in sequence, fixing the sleeve to the connecting surface, thereby connecting the guide plate to the pile body.

[0010] Compared with the prior art, the advantages of this utility model are as follows: the front and rear faces of the corrugated pile are both forward-convex arc-shaped surfaces, which not only allows the corrugated pile to be formed by centrifugal method, but also makes the stress distribution of the corrugated pile more reasonable, thereby improving the structural strength of the corrugated pile; in addition, the front face of the corrugated pile is provided with concave stop and convex stop. Compared with convex ribs and slots, the manufacturing process of concave stop and convex stop is simpler. Through the cooperation of concave stop and convex stop, adjacent corrugated piles can be quickly spliced ​​together for use as enclosure.

[0011] The second technical problem to be solved by this utility model is to provide a splicing wall made of the above-mentioned corrugated piles, in view of the current state of the prior art.

[0012] The technical solution adopted by this utility model to solve the second technical problem is as follows: the splicing wall is characterized in that it includes multiple corrugated piles as described above, and the piles are spliced ​​together by inserting the convex stop into the concave stop of the adjacent pile to form a splicing wall.

[0013] The aforementioned piles are spliced ​​together with the same orientation to form a splicing wall. That is, the front and rear faces of each corrugated pile protrude forward, so that the front ends of each arc-shaped front face are on the same plane. The splicing wall is roughly M-shaped, which makes the stress on each corrugated pile of the splicing wall uniform and the stability of the splicing wall better.

[0014] As another option, a type of spliced ​​wall is characterized by comprising multiple corrugated piles as described above. The pile body is spliced ​​in opposite directions to an adjacent pile body, and the protruding stop of the pile body interlocks with the protruding stop of the adjacent pile body to form a corrugated spliced ​​wall. The corrugated piles are spliced ​​in opposite directions to adjacent corrugated piles, meaning the pile bodies are not aligned with each other, forming a corrugated spliced ​​wall with peaks and troughs, i.e., an S-shaped spliced ​​wall. Compared to a straight wall, this type of spliced ​​wall enhances structural safety, reduces the risk of collapse, and is also more aesthetically pleasing.

[0015] Compared with the prior art, the advantages of this utility model are as follows: multiple corrugated piles are spliced ​​together by the cooperation of concave and convex stops or the cooperation of convex stops to convex stops to form an M-shaped or S-shaped splicing wall. Among them, the concave and convex stops of the corrugated piles are easy to insert, which facilitates the installation of the splicing wall; and the splicing effect of the concave and convex stops of the corrugated piles is better, making the splicing of multiple corrugated piles more reliable, thereby improving the structural strength of the splicing wall.

[0023] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments.

[0024] like Figures 1-4 As shown, this is Embodiment 1 of the present invention.

[0025] like Figures 1-4As shown, the corrugated pile of this embodiment includes a pile body 1, a thickened part 2, and a guide plate 3. The pile body 1 includes a front end face 11, a rear end face 12, and a connecting surface 13 connecting the ends of the front end face 11 and the rear end face 12. The connecting surface 13 is a plane, and the front end face 11 and the rear end face 12 are arc-shaped surfaces that convex forward. The outer sides of the left and right ends of the front end face 11 are respectively provided with concave stop 111 and convex stop 112 extending along the length direction of the pile body 1. The convex stop 112 is correspondingly provided with the concave stop 111, that is, the concave stop 111 has two adjacent inclined surfaces 111a. The connection of the inclined surfaces 111a is set at an obtuse angle. The two outer end faces 112a of the convex stop 112 are correspondingly set with the two inclined surfaces 111a of the concave stop 111. The connection between the convex stop 112 and the front end face 11 is provided with a clearance notch 113. The clearance notch 113 is correspondingly set with the connection between the concave stop 111 and the front end face 11. Through the cooperation of the concave stop 111 and the convex stop 112, and the cooperation of the clearance notch 113 with the connection between the concave stop 111 and the front end face 11, adjacent corrugated piles can be quickly spliced ​​together for use as retaining walls. Furthermore, the rear end face 12 forms an arc-shaped groove 14 extending along the length of the pile body 1. The top of the arc-shaped groove 14 is provided with a thickened part 2. The top wall of the thickened part 2 is flush with the top wall of the pile body 1. The bottom surface 21 of the thickened part 2 is an inclined surface that gradually slopes downward from the outside to the inside. The thickened section 2 increases the cross-sectional area of ​​the pile head and its strength. During pile driving, the increased contact area between the pile hammer and the pile head disperses the impact force of the hammer, and the increased strength of the pile head effectively prevents the pile head from cracking or breaking during the pile driving process. This ensures the aesthetics of the retaining wall and the structural performance of the concrete pile. Compared with adding metal end plates, the thickened section 2 is more cost-effective and requires no additional fixing steps. Only adaptive adjustments to the sheet pile mold are needed, making the process simple.

[0026] In addition, in this embodiment, a plurality of guide plates 3 are provided on a connecting surface 13 of the pile body 1 for guiding. One end of the guide plate 3 is fixed to the connecting surface 13 by pre-embedded steel bars, and the other end of the guide plate 3 is exposed outside the pile body 1. In this embodiment, the connecting surface 13 is a plane. During the manufacturing of the pile body 1, steel bars are pre-embedded at the positions corresponding to the guide plates 3, and then the guide plates 3 are welded to the pre-embedded steel bars, thereby installing the guide plates 3 on the pile body 1. When two adjacent corrugated piles are spliced, the guide plate 3 of one corrugated pile exposed outside the pile body 1 abuts against the connecting surface 13 of the adjacent corrugated pile, thereby improving the splicing effect of the two corrugated piles. The corrugated piles can be spliced ​​together with consistent orientation and tightness to form a splicing wall. Furthermore, the connecting surface 13 between the guide plate 3 and the pile body 1 has other fixing methods, such as one end of the guide plate 3 having an installation hole 31, and the connecting surface 13 having a connecting hole 131 corresponding to the installation hole 31. One end of the guide plate 3 is fixed to the connecting surface 13 by means of a sleeve passing through the installation hole 31 and the connecting hole 131, and the other end of the guide plate 3 is exposed outside the pile body 1.

[0027] like Figure 5 and Figure 6 The image shown is Embodiment 2 of this utility model.

[0028] like Figure 5 and Figure 6 As shown, the splicing wall in this embodiment includes multiple corrugated piles of Embodiment 1. The pile body 1 of the corrugated pile is spliced ​​together by inserting the convex stop 112 into the concave stop 111 of the adjacent pile body 1 to form a splicing wall.

[0029] Each pile 1 is spliced ​​together with the same orientation to form a splicing wall. That is, the front end face 11 and the rear end face 12 of each corrugated pile protrude forward, so that the front end of each arc-shaped front end face 11 is on the same plane. The splicing wall is roughly M-shaped, so that each corrugated pile of the splicing wall is subjected to uniform force and the stability of the splicing wall is better.

[0030] like Figure 7 As shown, this is Embodiment 3 of the present invention.

[0031] like Figure 7 As shown, the splicing wall in this embodiment includes two corrugated piles of Embodiment 1. The pile body 1 is spliced ​​in the opposite direction to the adjacent pile body 1. The protruding stop 112 of the pile body 1 is inserted into the protruding stop 112 of the adjacent pile body 1 to form a corrugated splicing wall.

[0032] The corrugated piles are spliced ​​in opposite directions to the adjacent corrugated piles, that is, the orientation of pile 1 is not the same as that of the adjacent pile 1, forming a corrugated splicing wall with crests and troughs, namely an S-shaped splicing wall. Compared with straight walls, corrugated splicing walls can enhance the safety of the structure, reduce the risk of collapse, and are more aesthetically pleasing.
