Description

Technical Field

[0001] The utility model belongs to the field of water conservancy and hydropower engineering, and particularly relates to an assembled flood prevention wall. Background Art

[0002] Heavy rains require extensive post-disaster reconstruction, particularly flood control system projects. To prevent another flood before the next flood season arrives due to an incomplete flood control system, the task of constructing a flood control system is urgent and arduous. Flood walls are key structures in flood control systems. Existing flood walls are typically constructed of reinforced concrete or stone blocks, cast in situ, to ensure the wall's airtightness and integrity. These walls require site cleanup and foundation excavation before being cast, resulting in a long construction cycle that cannot meet the more urgent requirements of renovation and construction. To ensure completion before the flood season arrives, there is an urgent need to develop a flood wall that can be quickly constructed and installed. Utility Model Content

[0003] The purpose of the utility model is to provide an assembled flood wall, which adopts a prefabricated flood wall, is quickly installed to save time, and solves the problems of long construction period and numerous steps.

[0004] In order to achieve the above purpose, the technical solution adopted by the utility model is:

[0005] An assembled flood wall, comprising a flood wall foundation, a flood wall body, full-length bolts, and a flange connection plate;

[0006] The flood wall foundation comprises an integrated base and a fixing plate, the fixing plate being perpendicular to the base, and steel bars are pre-embedded next to the fixing plate on the base;

[0007] The flood control wall comprises an integrated vertical wall and an inclined support wall, the center of the side of the vertical wall is the inclined support wall, and the bottom surfaces of the vertical wall and the inclined support wall are on the same horizontal plane;

[0008] The bottom of the vertical wall is provided with a fixing groove that is completely fitted with the solid plate, and a plurality of reserved steel bar holes that match the embedded steel bars are provided on the bottom surface of the flood wall;

[0009] The vertical wall and the fixing plate are fixedly connected by using full-length bolts and flange connection plates.

[0010] Furthermore, a lifting ring is provided on the upper part of the flood wall.

[0011] Preferably, there are two lifting rings, evenly spaced at the center of gravity of the flood wall. These lifting rings can be embedded in the upper surface of the flood wall during prefabrication, or they can be bolted to the wall through holes provided in the flood wall. The presence of these lifting rings allows for direct crane installation to a designated location during flood wall assembly, providing ease of use without compromising flood control effectiveness.

[0012] Preferably, a through-length bolt hole is provided on the fixing groove of the vertical wall, and a through-length bolt hole is provided on the upper portion of the fixing plate, and the through-length bolt passes through the through-length bolt hole and the through hole on the flange connecting plate for fixing.

[0013] Alternatively, full-length bolts are pre-embedded on the fixing grooves of the vertical wall, and full-length bolt holes are pre-embedded on the upper portion of the fixing plate, and the full-length bolts pass through the through holes on the flange connection plate for fixing.

[0014] According to the above-mentioned setting method, the through-length bolts can be embedded in part when the flood wall is prefabricated, and the embedded part is firmly fixed. Alternatively, through-length bolt holes can be reserved when the flood wall is prefabricated, and longer through-length bolts can be used to pass through the flood wall during assembly and fixed with flange connecting plates.

[0015] Preferably, the flange connection plate is provided with two or more through-length bolts. When two through-length bolts are provided for each flange connection plate, one bolt is mounted on the flood wall body and the other on the fixing plate. When two or more through-length bolts are provided for each flange connection plate, some bolts are mounted on the flood wall body and the other bolts are mounted on the fixing plate. This arrangement provides a better and more secure connection between the flood wall foundation and the flood wall body.

[0016] Preferably, the angle between the vertical wall and the oblique supporting wall is 30-45 degrees. The degree of the angle can also be set according to actual needs, such as 20 degrees less than 30 degrees or 60 degrees greater than 45 degrees.

[0017] Preferably, the horizontal length of the fixing plate is less than or equal to the horizontal length of the vertical wall. When the length of the fixing plate is equal to the length of the vertical wall, the fixing plate needs to be provided with bosses and grooves that match those on the vertical wall. This arrangement ensures that the top and bottom of the flood wall are consistent during assembly.

[0018] Preferably, the vertical walls are provided with bosses on one side and matching grooves on the other. During assembly, the bosses of one vertical wall connect with the grooves of another vertical wall, and several vertical walls are connected together to form a flood wall of the desired length. Sealing strips made of water-swelling material can be installed in the joints between the bosses and grooves.

[0019] Preferably, the flood wall foundation and the flood wall body are prefabricated with concrete. In the present invention, both the flood wall foundation and the flood wall body can be prefabricated with concrete and then assembled when in use. Alternatively, the flood wall body can be prefabricated with concrete, while the flood wall foundation is temporarily cast with concrete on site. In this way, the two important components of the flood wall can be manufactured simultaneously, thereby saving construction time.

[0020] Compared with the prior art, the technical advantages of the present invention are:

[0021] The prefabricated flood wall of the utility model can be quickly assembled, and the construction is very convenient; the construction quality is high; the safety hazards of on-site construction are reduced; the waste of resources is reduced, and the project cost is reduced.
