Description

Technical Field

[0001] The utility model relates to the technical field of dikes and revetments in hydraulic structures, and particularly relates to an assembled dike and revetment structure. Background Technique

[0002] There are numerous rivers in our country. Dikes are an important part of the river flood control system in our country. When constructing traditional dikes, it is necessary to build toe protection, and then compact in layers. After compaction to the elevation of the dike top, slope repair is carried out. The procedures are numerous and the efficiency is not high. In addition, most of the dike toe protections are built with mortar rubble masonry, and most of the dike revetments are earth-rock slope protections. It is easy for the upper earth-rock to be scoured and the dike toe to be hollowed out under the water flow scouring, and it is easy to collapse. Therefore, the demand for a highly reliable dike and revetment structure is extremely urgent. Therefore, the anti-scouring and stability safety of the dike and revetment are extremely important.

[0003] The assembled dike and revetment structure is assembled on-site through precast components. In recent years, it has been widely used because it does not require the construction of toe protection and the trimming of the dike slope, and can greatly improve the construction efficiency of the dike. How to improve the overall stability and anti-scouring property of the dike and revetment is still a new problem that needs to be considered in the assembled dike and revetment structure. In view of this, this case is generated. Content of the Utility Model

[0004] The purpose of the utility model is to solve at least one of the technical problems existing in the prior art, and provide an assembled dike and revetment structure. By splicing the front edge surfaces of symmetric precast blocks, an upper-layer wavy curved surface can be constructed, which can increase the ornamental value of the dike and revetment. Through the rear tooth grooves and tooth walls of the precast structure, the stability of the upper and lower precast structures can be increased. Through the lateral connecting steel pipes on the side surfaces of the precast structure, the integrity of the left and right precast structures can be increased.

[0005] The utility model also provides an assembled dike and revetment structure with the above features, including a bottom-layer vertical precast block, a walkway, an upper-layer wavy precast block, a dike-top leisure platform, and a berm retaining wall. Among them, both the bottom-layer vertical precast block and the upper-layer wavy precast block are reinforced concrete frame structures. The upper-layer wavy precast block is divided into a No. 1 precast block and a No. 2 precast block, and the two are symmetrical. By splicing the front edge surfaces of the symmetric precast blocks, an upper-layer wavy curved surface can be constructed, which can increase the ornamental value of the dike and revetment.

The first tooth groove on the upper side of the rear part is 0.4 m lower than the top elevation of the front part, and the first tooth wall on the lower side of the rear part is 0.4 m lower than the bottom elevation of the front part. The first transverse steel pipe hole on the side is located in the middle of the rear part of the cavity and has a diameter of 0.1 m. By means of the tooth grooves and tooth walls at the rear of the bottom layer of vertical precast blocks, the stability of the upper and lower bottom layer precast structures can be increased.

[0008] According to the described assembled bank structure, the upper layer of corrugated precast blocks is also a precast cavity structure, including a corrugated front edge surface, a second vertical rear edge surface, a second tooth groove on the upper side of the rear part, a second tooth wall on the lower side of the rear part, and a second transverse steel pipe hole on the side. The reinforced concrete precast structure has good anti-scouring characteristics.

The wall thickness of the cavity structure is 20 cm. The bottom and top elevations of the rear part of the cavity are also staggered from those of the front part, with a staggering width of 1.0 m. The second tooth groove on the upper side of the rear part is 0.4 m lower than the top elevation of the front part, and the second tooth wall on the lower side of the rear part is 0.4 m lower than the bottom elevation of the front part. The second transverse steel pipe hole on the side is located in the middle of the rear part of the cavity and has a diameter of 0.1 m. By means of the tooth grooves and tooth walls at the rear of the upper layer of corrugated precast blocks, the stability of the upper layer of corrugated precast structures can be increased.
