Building construction rainfall drainage structure

Abstract

The invention discloses a building construction rainfall drainage structure. The building construction rainfall drainage structure comprises a drainage channel, wherein the upper end of the drainage channel is open, the inner bottom wall of the drainage channel is obliquely arranged downwards from left to right, a water seepage net plate is fixedly connected to the upper end of the drainage channel in a sealed mode, two rows of circular insertion blocks which are symmetrical about the transverse axis of the water seepage screen plate are fixedly embedded in the upper end of the water seepage screen plate, a water pumping rod is vertically and movably inserted in each circular insertion block, the lower end of each water pumping rod extends into the drainage channel, a water suction cavity is formed in each water pumping rod, the lower end of each water suction cavity communicates with the drainage channel, a plurality of water inlets are formed in the peripheral surface of the upper end of each water pumping rod, and fixed blocks are fixedly connected to the front and rear positions of the end, which is located in the drainage channel, of each water pumping rod. The building construction rainfall drainage structure has the advantages that rainfall accumulated water of a construction site can be continuously and effectively drained, the structure adapts to different rainfall intensities and has the effects of energy conservation and environment friendliness, and the water level is prevented from rising.

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, due to the imperfect drainage system, 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 soaked and damaged for a long time, and the construction cannot be resumed in time. In order to resume construction in time, construction workers will set up drainage structures on the construction site to discharge rainwater in time. [0003] After searching, the public number CN211499114U provides a construction rainfall drainage structure, including a base plate and an upper filter plate, an upper filter plate is fixedly installed above the base plate, a slope is fixedly installed at the bottom of the base plate, an...

AI Technical Summary

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
