Introduction to flood control artifact

　　Flood control artifact is a new flood control product specially used for urban flood control, especially suitable for urban streets, doorways, underpasses, buildings and so on. It can also be used to reinforce hard levees to prevent overflows. The flood control artifact adopts unit module design, good sealing, can form a diversified partition area, and fast drainage speed. It has the advantages of simple operation, quick installation, convenient disassembly, reusable, convenient transportation and storage. Due to the large span of the unit flood control wall, the baffle can be removed as a vehicle channel in an emergency. The flood control wall adopts special aluminum structure instead of the traditional sandbag stacking method, which reduces the labor intensity. The water retaining wall is equipped with a special sealing device to ensure the reliability of the product. Structure: mainly composed of base, column, baffle and sealing device.

　　General technical parameters of flood control artifact: Applicable base: concrete layer ≥80mm; Asphalt pavement hard base ≥80mm Design wind speed :6.0m/s embedded ground railway. If the ground is uneven, the channel steel ground rail must be embedded (the length of the ground rail must not be less than the length of the installation column).

　　Install the column on the vertical surface between the wall and the ground rail, and fix the middle column on the pre-embedded part. (Before installing the column, ensure that the wall is perpendicular to the ground, and make sealing structural adhesive on the contact surface between the column and the wall and the ground rail.) Clamp the aluminum alloy water baffle plate in parallel, put down the rubber strip behind the plate, install the top compression member, and use a hex key to tighten the top and the hex screws on the side of the column one by one. Parallel screw tightening shall prevail).

　　After use, remove the aluminum alloy water baffle and the middle column in turn. The bottom screw of the middle column is left in the upper embedded part to prevent the ash layer from falling into the screw hole and affecting the use. The flood control board is placed on the wall parts, ready for next use, and the adhesive strip is placed upward to avoid damage. The seasonal flood season is coming, urban flood control is an important step of society, the vast majority of low-lying areas need to be waterproof and hydrophobic, specific places need to use general flood control artifact materials for flood control work, to this end, the setting and use of flood control materials is very important, the details also need to be managed well.
