Description

Technical Field

[0001] This invention relates to the field of sheet pile technology, specifically to prefabricated sheet pile structures. Background Technology

[0002] Channel improvement projects involve the planning and construction of various facilities along a waterway. Bank protection is an engineering measure that artificially reinforces existing bank slopes to protect against wave and current erosion, as well as groundwater action, thus maintaining shoreline stability. Bank protection structures are similar in form to seawalls, and can be classified according to their outer slope type: sloping bank protection, steep-wall protection (including vertical protection), and a combination of both. The facing structure and coverage area of ​​sloping bank protection are the same as those of sloping seawalls, with the top of the slope being land.

[0003] Patent No. CN201120490612.5 discloses a novel composite revetment structure, which includes steel sheet piles, steel pipe piles, and reinforced concrete foundations. The steel sheet piles are closely and continuously arranged along the riverbank revetment, and the steel pipe piles are distributed on the bank side of the steel sheet piles. The steel sheet piles and steel pipe piles are connected by the reinforced concrete foundations to form a load-bearing whole. It can be applied to waterway and revetment engineering, especially in sections where the construction site is limited, the revetment is adjacent to existing buildings, and the structural displacement control requirements are high, and it has good results.

[0004] In existing technologies, sheet piles are generally driven into the foundation using a dynamic compaction machine. Therefore, when the sheet pile is long, if there is no support structure, the middle part of the sheet pile is prone to bending during the dynamic compaction process. When the sheet pile is short, although it is easy to drive it into the foundation, the protection range is relatively small. Summary of the Invention

[0005] The purpose of this invention is to provide a prefabricated sheet pile structure to solve the problems in the prior art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a prefabricated sheet pile structure, comprising fixed sheet piles and spliced ​​sheet piles; the fixed sheet pile consists of a fixed sheet pile body and a connecting sleeve one, wherein two connecting sleeves one are provided and vertically fixed to the upper part of the middle of the inner surface of the fixed sheet pile body; the spliced ​​sheet pile consists of a spliced ​​sheet pile body, a connecting sleeve two, and connecting rods, wherein two connecting rods are provided and vertically fixed to the lower part of the middle of the inner surface of the spliced ​​sheet pile body, and two connecting sleeves two are provided and vertically fixed to the upper part of the middle of the inner surface of the spliced ​​sheet pile body; the connecting rods cooperate with connecting sleeve one and connecting sleeve two.

[0007] Preferably, a first protective plate is fixedly installed at the lower middle part of the inner surface of the spliced ​​sheet pile body, the first protective plate is located between two connecting rods, and a second protective plate is fixed at the lower part of each side of the inner surface of the spliced ​​sheet pile body, the length of the first protective plate and the second protective plate extending out of the spliced ​​sheet pile body is greater than the length of the connecting rod extending out of the spliced ​​sheet pile body.

[0008] Preferably, the length of each connecting rod is greater than the length of both connecting sleeve one and connecting sleeve two.

[0009] Preferably, a thickened portion is fixedly provided in the upper middle part of the front surface of the fixed sheet pile body.

[0010] Compared with the prior art, the beneficial effects of the present invention are as follows: The present invention consists of fixed sheet piles and spliced ​​sheet piles, wherein one fixed sheet pile can be equipped with multiple spliced ​​sheet piles. The lengths of both the fixed sheet piles and spliced ​​sheet piles in the present invention are relatively short. The shorter fixed sheet piles are easier to drive into the foundation and are less prone to bending. The shorter spliced ​​sheet piles are easier to assemble onto the top of the fixed sheet piles. The fixed sheet piles and spliced ​​sheet piles are connected by the cooperation of a connecting sleeve one and a connecting rod. The spliced ​​sheet piles are connected by the cooperation of a connecting sleeve two and a connecting rod. In summary, the present invention is simple to assemble and disassemble and is less prone to sheet pile bending.

[0011] Because the spliced ​​sheet pile body is equipped with a first protective plate and a second protective plate, and the lengths of the first and second protective plates extending out of the spliced ​​sheet pile body are both greater than the lengths of the connecting rod extending out of the spliced ​​sheet pile body, the connecting rod will be blocked by the first and second protective plates before an external object impacts it, making the connecting rod less likely to bend due to the collision, which helps to extend the service life of the spliced ​​sheet pile.

Two connecting sleeves 5 are provided and vertically fixed to the upper part of the middle of the inner surface of the fixed sheet pile body 4. The spliced ​​sheet pile 2 consists of a spliced ​​sheet pile body 6, a connecting sleeve 2 10 and a connecting rod 9.

The fixed sheet piles 1 and spliced ​​sheet piles 2 are connected by the cooperation of connecting sleeve 1 5 and connecting rod 9. The spliced ​​sheet piles 2 are connected by the cooperation of connecting sleeve 2 10 and connecting rod 9. In summary, this invention is simple to assemble and disassemble and is less prone to sheet pile bending.

[0021] A first protective plate 8 is fixedly installed at the lower middle part of the inner surface of the spliced ​​sheet pile body 6, between two connecting rods 9. A second protective plate 7 is fixed at the lower part of each side of the inner surface of the spliced ​​sheet pile body 6. The lengths of the first protective plate 8 and the second protective plate 7 extending out of the spliced ​​sheet pile body 6 are both greater than the lengths of the connecting rods 9 extending out of the spliced ​​sheet pile body 6. Because the spliced ​​sheet pile body 6 is equipped with the first protective plate 8 and the second protective plate 7, and the lengths of the first protective plate 8 and the second protective plate extending out of the spliced ​​sheet pile body 6 are both greater than the lengths of the connecting rods 9 extending out of the spliced ​​sheet pile body 6, foreign objects will be blocked by the first protective plate 8 and the second protective plate 7 before they hit the connecting rods 9, making it less likely for the connecting rods 9 to bend due to collision, which helps to extend the service life of the spliced ​​sheet pile 2.

[0022] The length of connecting rod 9 is greater than the length of connecting sleeve 5 and connecting sleeve 10.

[0023] A thickened part 3 is fixedly provided in the upper middle part of the front surface of the fixed sheet pile body 4. The thickened part 3 can make the top of the fixed sheet pile body 4 more solid, so that the top of the fixed sheet pile body 4 is not easily deformed by dynamic compaction.

[0024] The working principle of this invention is as follows: This invention consists of fixed sheet piles 1 and spliced ​​sheet piles 2. One fixed sheet pile 1 can be equipped with multiple spliced ​​sheet piles 2. The fixed sheet piles 1 and spliced ​​sheet piles 2 of this invention are both relatively short in length. The shorter fixed sheet piles 1 are easier to drive into the foundation and are less prone to bending.
