Description

Technical Field

[0001] This utility model relates to the field of bank protection technology, and in particular to a plastic steel sheet pile bank protection structure. Background Technology

[0002] Revetments are engineering measures that artificially reinforce existing coastal slopes to defend against the erosion and scouring of waves and currents, as well as the effects of groundwater, and to maintain the stability of the shoreline. The construction forms of revetments are similar to those of seawalls. According to their outer slope forms, they can be divided into sloping revetments, steep wall revetments, and revetments that combine the two.

[0003] Plastic-coated steel sheet piles are made of high-molecular-weight plastic, which is lightweight and high-strength. They are not corroded by seawater or freshwater even after long-term use. They are spliced ​​together to form a protective wall to buffer and block the impact of river water, thereby protecting the riverbank.

[0004] The existing plastic-steel sheet pile revetment has the following defects in actual use:

[0005] Most existing plastic steel sheet pile revetments use a combination of plastic steel sheet piles and precast concrete square piles. However, in this type of revetment, the precast concrete square piles and plastic steel sheet piles do not form a whole; they are simply sunk into the soil separately and placed adjacent to each other. As a result, the protective effect of the concrete square piles on the plastic steel sheet piles is greatly reduced, and the plastic steel sheet piles on the revetment are prone to falling off. Utility Model Content

[0006] In view of the existing technology, most existing plastic steel sheet pile revetments are used in combination with precast concrete square piles. However, in this type of revetment, the precast concrete square piles and plastic steel sheet piles are not formed as a whole, but are simply sunk into the soil layer and set up adjacent to each other. As a result, the protective effect of the concrete square piles on the plastic steel sheet piles is greatly reduced, and the plastic steel sheet piles of the revetment are prone to falling off. This utility model provides a plastic steel sheet pile revetment structure.

[0007] The technical solution adopted by this utility model is: a plastic steel sheet pile revetment structure, including a number of sheet piles, a number of capping mechanisms, and a number of precast concrete piles. The precast concrete piles are arranged between two adjacent sheet piles. A connecting mechanism is provided on both sides of the precast concrete piles and between each of the two adjacent sheet piles. The connecting mechanism includes a fixing plate, a snap-fit ​​plate, and a connecting plate. The fixing plate is fixedly installed on one side of the sheet pile, the snap-fit ​​plate is fixedly installed on one side of the connecting plate, and the connecting plate is arranged on one side of the precast concrete pile. Snap-fit ​​grooves are provided on both sides of the fixing plate, and the snap-fit ​​plates snap into the corresponding snap-fit ​​grooves.

[0008] Furthermore, there are two of each of the snap-fit ​​plates and the connecting plates, and the number of snap-fit ​​slots corresponds to the number of snap-fit ​​plates.

[0009] Furthermore, adjustment mechanisms are provided on both sides of the precast concrete pile, the adjustment mechanisms are corresponding to the fixed plates, and both connecting plates are connected to one side of the adjustment mechanism.

[0010] Furthermore, the adjustment mechanism includes an embedded part, a bidirectional screw, and two threaded sliders. The embedded part has a sliding groove on one side, the bidirectional screw is rotatably installed in the sliding groove, and the threaded sliders are threaded to both ends of the bidirectional screw.

[0011] Furthermore, both threaded sliders are slidably installed in the sliding groove, and the two threaded sliders are respectively fixedly connected to the two connecting plates. Both sides of the precast concrete pile are provided with embedded grooves, and the embedded parts are set in the embedded grooves.

[0012] Furthermore, the capping mechanism includes a concrete capping, a connecting screw, and a fixing nut. The concrete capping is sleeved on the upper end of the two connected sheet piles and the precast concrete pile. Through holes are opened on both sides of the concrete capping, and insertion slots are opened on one side of the precast concrete pile and the two connected sheet piles. The connecting screw is inserted between the corresponding through hole and the insertion slot, and the fixing nut is threaded to one end of the connecting screw.

[0013] Furthermore, a T-shaped clamping plate is fixedly installed at one end of the sheet pile, and a T-shaped clamping groove is opened at the other end of the sheet pile, with the T-shaped clamping plate cooperating with the T-shaped clamping groove.

[0014] The beneficial effects of this utility model are:

[0015] This utility model, through a connecting mechanism, enables the sheet piles to be fixedly connected to the precast concrete piles during installation, thereby improving the protective effect of the precast concrete piles on the sheet piles and effectively preventing the sheet piles from falling off. This makes the plastic steel sheet pile revetment structure more stable and reliable during use.

[0016] Secondly, this utility model, through the adjustment mechanism, facilitates the operation of the connection mechanism by workers when connecting the sheet piles and the precast concrete piles, thereby fixing the sheet piles and precast concrete piles together and improving the convenience of installing the plastic steel sheet pile revetment structure.

[0024] The following is in conjunction with the appendix Figures 1-4 The present invention will be further described below.

[0025] In order to solve the problems existing in the background technology, this application proposes the following technical solution: a plastic steel sheet pile revetment structure.

[0026] The specific technical solution includes several sheet piles 1, several capping mechanisms 2, and several precast concrete piles 3. The precast concrete piles 3 are positioned between two adjacent sheet piles 1. Connecting mechanisms 5 are provided on both sides of the precast concrete piles 3 and between each of the two adjacent sheet piles 1. Each connecting mechanism 5 includes a fixing plate 13, a snap-fit ​​plate 15, and a connecting plate 16. The fixing plate 13 is fixedly installed on one side of the sheet pile 1, the snap-fit ​​plate 15 is fixedly installed on one side of the connecting plate 16, and the connecting plate 16 is positioned on one side of the precast concrete pile 3. Snap-fit ​​grooves 14 are provided on both sides of the fixing plate 13, and the snap-fit ​​plates 15 snap into the corresponding snap-fit ​​grooves 14. There are two snap-fit ​​plates 15 and two connecting plates 16, and the number of snap-fit ​​grooves 14 corresponds to the number of snap-fit ​​plates 15. Adjusting mechanisms 4 are provided on both sides of the precast concrete piles 3, corresponding to the fixing plates 13, and both connecting plates 16 are connected to the adjusting mechanisms. The adjustment mechanism 4 is connected to one side of the precast concrete pile 3. The adjustment mechanism 4 includes a precast part 18, a bidirectional screw 20, and a threaded slider 21. There are two threaded sliders 21. A sliding groove 19 is opened on one side of the precast part 18. The bidirectional screw 20 is rotatably installed in the sliding groove 19. The threaded sliders 21 are threadedly connected to both ends of the bidirectional screw 20. Both threaded sliders 21 are slidably installed in the sliding groove 19, and both threaded sliders 21 are fixedly connected to two connecting plates 16. Precast grooves 17 are provided on both sides of the precast concrete pile 3. The precast part 18 is set in the precast concrete pile 3. By setting the precast concrete pile 3 between two adjacent sheet piles 1, and connecting the precast concrete pile 3 to the two adjacent sheet piles 1 through the connecting mechanism 5, the stability of the two sheet piles 1 after connection can be improved. The precast part 18 is pre-embedded in the precast concrete pile 3 during the precasting process.

[0027] Refer to 1 and Figure 2 As shown, the capping mechanism 2 includes a concrete capping 6, a connecting screw 9, and a fixing nut 10. The concrete capping 6 is sleeved on the upper ends of the two connected sheet piles 1 and precast concrete piles 3. Through holes 8 are opened on both sides of the concrete capping 6. Insertion slots 7 are opened on one side of the precast concrete piles 3 and the two connected sheet piles 1. The connecting screw 9 is inserted between the corresponding through holes 8 and insertion slots 7. The fixing nut 10 is threaded to one end of the connecting screw 9. A T-shaped clamping plate 11 is fixedly installed at one end of the sheet pile 1, and a T-shaped clamping groove 12 is opened at the other end of the sheet pile 1. The T-shaped clamping plate 11 and the T-shaped clamping groove 12 cooperate. The concrete capping 6 is precast, with a horizontal plate on the upper part and two vertical plates perpendicular to the horizontal plate at the lower part. By fixing the concrete capping 6 to the plastic steel sheet piles 1 and the precast concrete piles 3 through the connecting screw 9 and the fixing nut 10, a stable whole can be formed, which improves the overall stability of the plastic steel sheet pile revetment structure and enhances the safety of the revetment.

[0028] To ensure that those skilled in the art can fully understand the technical solution, this application provides the following overall overview:

[0029] In use, several sheet piles 1 are connected to each other by T-shaped clamping plates 11 and T-shaped clamping slots 12 and buried in the installation position. Then, precast concrete piles 3 are buried between the concave surfaces of the connection between two sheet piles 1. Then, the bidirectional screw 20 is rotated, which drives two threaded sliders 21 to move synchronously in opposite directions along the sliding groove 19. The synchronous movement of the two threaded sliders 21 can drive the two connecting plates 16 to move synchronously in opposite directions. The synchronous movement of the two connecting plates 16 can drive the two clamping plates 15 to move synchronously in opposite directions. Thus, the two clamping plates 15 are synchronously clamped into the clamping slots 14 on the upper and lower sides of the fixing plate 13. By the two clamping plates 15 being clamped into the clamping slots 14, the sheet piles 1 can be fixedly connected to the precast concrete piles 3, which improves the protective effect of the precast concrete piles 3 on the sheet piles 1, thereby effectively preventing the sheet piles 1 from falling off. This makes the plastic steel sheet pile revetment structure more stable and reliable in use.
