Accumulated water drainage device for building construction

Abstract

The invention discloses an accumulated water drainage device for building construction. The device comprises a barrel body, wherein the top of the barrel body is slidably connected with a connecting block, the interior of the connecting block is in threaded connection with a threaded rod, the lower end of the threaded rod is rotatably connected with a top plate, the upper side of the barrel body is fixedly provided with a spring barrel, and a sliding block is slidably connected to the interior of the spring barrel. When the water level in the barrel is higher than the height of the end opening of a drainage pipe, a pull block is pulled outwards, a clamping block is separated from a clamping groove formed in the surface of the connecting block, a stretched fifth spring drives a threaded rod and the connecting block to move upwards through the top plate, and water higher than the end opening of the drainage pipe in the barrel flows into the drainage pipe to be drained; at the moment, a certain negative pressure space is formed between water falling from the drainage pipe and the end opening of the drainage pipe, so that more water is continuously sucked into the drainage pipe, accumulated water can be rapidly discharged from the drainage pipe through the barrel body, rapid cleaning of the accumulated water is achieved, and compared with manual cleaning, the device has the advantages of being faster and more labor-saving.

Description

technical field [0001] The invention relates to the construction field, in particular to a water drainage device for building construction. Background technique [0002] It is inevitable to encounter heavy rain during the construction process, which will cause more rainwater to accumulate on the balconies and terraces in the built frame. If the rainwater is not discharged in time, it will cause certain corrosion to the house structure and water seepage after a long time In the case of water leakage, drainage pipes will be reserved at the balcony or terrace. In order to decorate the floor tiles in the future, the drainage pipes will be higher than the floor level, making it difficult to drain the accumulated water. Most of the existing treatment methods are manually cleaned, and the cleaning process is relatively cumbersome. Contents of the invention [0003] The present invention mainly solves the technical problems in the above-mentioned prior art, and provides a water d...
