Description

Technical Field

[0001] This utility model relates to the field of water conservancy engineering construction technology, and in particular to a combined concrete and plastic steel sheet pile revetment structure. Background Technology

[0002] Bank protection is an engineering measure that involves artificially reinforcing existing riverbank slopes to defend against wave and current erosion, as well as the effects of groundwater, and to maintain shoreline stability. Currently, plastic steel sheet piles or concrete piles are widely used for bank protection structures to reinforce riverbank slopes.

[0003] Patent document “201510048371.1” discloses “a revetment structure combining plastic steel sheet piles and concrete”, which includes plastic steel sheet piles and concrete capping. The plastic steel sheet piles are connected by matching connectors at both ends, and the concrete capping is prefabricated and can be stably fastened to the upper end of the sheet piles.

[0004] The existing concrete capping technology mentioned above uses a snap-fit ​​method for fixing. This snap-fit ​​method is relatively unstable. If the river has a strong scouring force or if construction workers step on the capping, it is very easy for the capping to fall off, affecting the stability of the overall revetment structure. Utility Model Content

[0005] The purpose of this invention is to overcome the shortcomings of the existing technology and provide a combined concrete and plastic steel sheet pile revetment structure, which makes the combined revetment structure highly reinforced and more stable.

[0008] The plastic steel sheet pile unit includes multiple sheet piles, with connecting sheet piles between any two adjacent sheet piles; the inside of the sheet pile is hollow, and a concrete pile is installed inside the sheet pile, with the concrete capping connected to the concrete pile by pouring.

[0009] A further provision of this technical solution is that the top surface of the concrete pile is flush with the top surface of the sheet pile, and the reinforcing bars of the concrete pile protrude from the top surface of the concrete pile.

[0010] A further feature of this technical solution is that a support member for supporting the concrete pile is provided in the middle of the inner wall of the sheet pile.

[0011] A further feature of this technical solution is that at least one flow guide hole is provided through the lower part of the sheet pile.

[0012] A further setting of this technical solution is that the cross-section of the sheet pile is rectangular, circular, semi-circular, trapezoidal, wedge-shaped, pentagonal, hexagonal or octagonal.

[0014] A further setting of this technical solution is that the first connecting portion and the third connecting portion are of a "T" - shaped structure, and the second connecting portion and the fourth connecting portion are of a "C" - shaped groove.

[0015] A further setting of this technical solution is that the connecting sheet pile includes a water-facing surface and a soil-facing surface, and a first concrete pile is further arranged outside the water-facing surface.

[0016] A further setting of this technical solution is that the connecting sheet pile is of a "U" - shaped structure.

[0017] The utility model discloses a combined revetment structure of concrete and plastic steel sheet piles. Compared with the prior art:

[0018] In this technical solution, by arranging a concrete pile in the sheet pile, and then making the concrete coping cast and connected with the concrete pile, the combination of the concrete coping and the plastic steel sheet pile unit is more stable and firm; the steel bars of the concrete pile protrude outside the concrete pile, making the combination closer; by arranging a first concrete pile outside the water-facing surface of the connecting sheet pile, the whole revetment structure can be made more firm and stable, not easy to fall off, and can play a good supporting effect.

[0025] See Figure 1 and Figure 2 As shown, the concrete and plastic steel sheet pile combined revetment structure includes a plastic steel sheet pile unit 10 and a concrete capping 20 disposed on the upper end of the plastic steel sheet pile unit 10. The concrete capping 20 is prefabricated and has a rectangular structure, covering the upper end of the plastic steel sheet pile unit 10. The plastic steel sheet pile unit 10 includes multiple sheet piles 30, and a connecting sheet pile 40 is provided between any two adjacent sheet piles 30. The interior of the sheet pile 30 is hollow, and a concrete pile 50 is disposed inside the sheet pile 30. The concrete capping 20 is cast and connected to the concrete pile 50. In the above technical solution, the concrete capping 20 and the concrete pile 50 are connected together by casting, so that the concrete capping 20 will not easily detach from the plastic steel sheet pile unit 10. The concrete capping 20 mainly serves to reinforce the plastic steel sheet piles. The function of unit 10; the concrete piles 50 inside the sheet piles 30 can make the entire plastic steel sheet pile unit 10 more stable; this revetment structure has two assembly methods. The first method is to first assemble the plastic steel sheet pile units 10, then place the concrete piles 50 inside the sheet piles 30, the concrete capping 20 is a precast component, then lay the formwork outside the plastic steel sheet pile units 10, pour concrete in place, and then place the concrete capping 20 on the top of the plastic steel sheet pile units 10, and wait for the concrete to harden so that the two are fixed together; the second method is to first assemble the plastic steel sheet pile units 10, then place the concrete piles 50 inside the sheet piles 30, then lay the formwork outside the plastic steel sheet pile units 10, pour concrete in place, so that the concrete capping 20 is poured at the top of the plastic steel sheet pile units 10.

[0026] See Figure 2 As shown, the top surface of the concrete pile 50 is flush with the top surface of the sheet pile 30, and the reinforcing bar 501 of the concrete pile 50 protrudes from the top surface of the concrete pile 50. Since concrete needs to be poured at the top of the concrete pile 50, the setting of the reinforcing bar 501 can make the connection between the concrete pile 50 and the concrete capping 20 more firm and stable. It is worth noting that the concrete pile 50 can be rectangular, circular, semi-circular, polygonal, etc.

[0027] As a further preferred embodiment of this technical solution, a support member for supporting the concrete pile 50 is provided in the middle of the inner wall of the sheet pile 30. The support member can support the concrete pile 50. Since the concrete pile 50 mainly plays the role of counterweight and connection in this technical solution, considering the production cost factor, the height of the concrete pile 50 is not higher than half of the sheet pile 30. Therefore, the support member inside the sheet pile 30 can support the concrete pile 50. It is worth noting that the support member can be triangular, ring-shaped or other shapes. Furthermore, in order to prevent the support member from being unstable, multiple support rods can be provided at the lower end of the support member to ensure that the concrete pile 50 will not fall.

[0028] See Figure 2 As shown, at least one flow guide hole is penetrating the lower part of the sheet pile 30; the flow guide hole is mainly used for water flow.

[0029] As a preferred embodiment of this technical solution, the cross-section of the sheet pile 30 is rectangular, circular, semi-circular, trapezoidal, wedge-shaped, pentagonal, hexagonal, or octagonal.

[0030] See Figure 2 As shown, the sheet pile 30 is provided with a first connecting part 301 and a second connecting part 302 on both sides, and the connecting sheet pile 40 is provided with a third connecting part 401 and a fourth connecting part 402 on both sides, which cooperate with and connect to the first connecting part 301 and the second connecting part 302. The first connecting part 301 and the third connecting part 401 are "T" shaped structures, and the second connecting part 302 and the fourth connecting part 402 are "C" shaped grooves. The first connecting part 301 is arranged along the longitudinal direction of the sheet pile 30, the third connecting part 401 is arranged along the longitudinal direction of the connecting sheet pile 40, the second connecting part 302 is arranged along the longitudinal direction of the sheet pile 30, and the fourth connecting part 402 is arranged along the longitudinal direction of the connecting sheet pile 40.

[0031] See Figure 2As shown, the connecting sheet pile 40 includes a water-facing surface 403 and a soil-facing surface 404. A first concrete pile 60 is further provided on the outer side of the water-facing surface 403. The first concrete pile 60 contacts the connecting sheet pile 40, which can make the entire plastic sheet pile unit 10 more stable. At the same time, the steel bars of the first concrete pile 60 also protrude upward, so that during the later pouring, the concrete coping 20 is more firmly combined with the entire plastic sheet pile unit 10.

[0032] A further setting of this technical solution is that the connecting sheet pile 40 has a "U" - shaped structure.

[0033] It should be noted that as another embodiment of this technical solution, the height of the concrete pile 50 is the same as the height of the sheet pile 30, which can make the entire plastic sheet pile unit 10 more stable.

[0034] The above is only the preferred specific implementation mode of the present utility model, but the protection scope of the present utility model is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present utility model, according to the technical solution of the present utility model and its utility model concept, makes equivalent substitutions or changes, and should be covered within the protection scope of the present utility model. It should be noted that in the translation of , it is assumed that the "几" - shaped structure is actually a "U" - shaped structure in English. If it is a different shape, it needs to be accurately translated according to the actual shape.
