Construction method using connection connection for prevention of injury and leakage of light drainage

摘要

The present invention relates to the construction of a lightweight drainage port for rainwater drainage installed at the upper or middle end of a cutout or embankment slope at the time of road construction or in the construction of a complex, The water leakage and the leak-barrier cushioning material are installed in the concave grooves on the right and left sides of the connection connector, so that the water leakage and the expansion and contraction due to the temperature change can be buffered and absorbed, The vertical plate and the horizontal plate are firmly assembled to form a skeleton that can withstand the deformation of the lightweight drainage port by the lateral earth pressure and the lightweight drainage port caused by the increase of the groundwater level and the water content of the soil due to the weight of the backed-Which is frequently caused by the construction of the lightweight drainage port, One way to solve the culvert construction, lightweight kind of endemic evils.
