A construction rainwater drainage structure

Abstract

The invention discloses a rainfall drainage structure for building construction, which comprises a drainage channel, the upper end of the drainage channel is provided with an opening, the inner bottom wall of the drainage channel is arranged downwardly from left to right, and the upper end of the drainage channel is sealed and fixedly connected with The water seepage screen, the top of the water seepage screen is fixed with two rows of circular plugs symmetrical to the transverse axis of the water seepage screen, and each of the circular plugs is vertically and movablely inserted with a pumping rod. The lower end of the pumping rod extends into the drain, and a water-absorbing cavity is opened in the pumping rod. The front and back positions of one end of the water pumping rod located in the drainage ditch are fixedly connected with fixed blocks. The advantage is that the present invention can continuously and effectively discharge the rainwater accumulated on the construction site, adapt to different rainfall intensities, avoid the rise of the water level, and have the effect of energy saving and environmental protection.

Description

technical field [0001] The invention relates to the technical field of building construction, in particular to a rainwater drainage structure for building construction. Background technique [0002] In the construction site, the drainage system is not perfect. When the rain occurs during the construction process, the rainwater cannot be discharged in time, which will cause the construction site to accumulate water, and then cause the building materials to be damaged by soaking for a long time, and the construction cannot be resumed in time. In order to resume construction in a timely manner, construction personnel will set up drainage structures on the construction site to drain rainwater and accumulated water in time. [0003] After searching, the publication number CN211499114U provides a rainwater drainage structure for building construction, including a bottom plate and an upper filter plate, an upper filter plate is fixedly installed on the top of the bottom plate, a sl...

Problems solved by technology

[0004] The above-mentioned documents can filter rainwater during the drainage process to prevent rainwater from carrying sundries and other pollutants into the sewer. However, in construction sites with a lot of sediment, when the rainfall is heavy, the accumulated water will bring the sediment to the top of the drainage structure , resulting in blockage of the filter plate, resulting in the rise of the water level above the filter plate, which cannot play a good drainage effect, and then cannot solve the problem of material soaking caused by the rise of the water level caused by heavy rainfall
