Technical Field

[0001] The utility model relates to the technical field of river embankments, and more specifically, to a prefabricated drainage ditch outside the embankment in a river embankment project. Background Art

[0002] River embankment projects are important water conservancy projects used to protect surrounding areas from floods. Their main purpose is to constrain the water level of the river by building dams, prevent flooding, thereby protecting personal safety and reducing property losses. In daily work, it is found that in the process of building drainage ditches, multiple prefabricated ditch bodies are often placed in pits dug in advance on the ground, and then multiple prefabricated ditch bodies are assembled to combine multiple ditch bodies into a complete drainage channel.

[0003] In the existing technology, when digging a pit, the bottom of the pit may be uneven or the area may not reach the specified height, which affects the smooth assembly of the ditch body. At the same time, the connection stability between the ditch units is poor, and the connection method is not convenient enough, which not only affects the installation efficiency, but also the ditch is prone to shifting and causing water seepage under the continuous impact of water flow, affecting the stability and integrity of the ditch connection. At the same time, when there are impurities such as branches in the ditch, it is difficult to salvage and it is easy to block the ditch, affecting the flood discharge and diversion effect of the ditch.
