Automatic rainwater lifting device in underground rainwater pipeline and construction method

Abstract

The invention discloses an automatic rainwater lifting device in an underground rainwater pipeline and a construction method. The method comprises the following steps of a, preparation before construction; b, assembling a collecting mechanism; c, stacking the collecting mechanism and a storage assembly; d, placing a horizontal base; and e, mounting. According to the automatic rainwater lifting device, the rainwater lifting device is arranged at the joint of the underground rainwater pipeline, so that rainwater in an underground rainwater pipeline is discharged into a water inlet groove in a collecting cavity through a water inlet pipe on the outer side of a collecting box, and the rainwater in the water inlet groove is filtered through a filtering assembly in the collecting cavity and then discharged into a drainage groove, rainwater in the drainage groove is sucked into the storage assembly through a drainage pump and then drained through the drainage pipe for centralized treatment, the rainwater in the rainwater pipeline is prevented from overflowing to a road, the safety of the road surface is guaranteed, and meanwhile it is avoided that the rainwater is accumulated in the underground rainwater pipeline for a long time and goes bad and smells.

Description

technical field [0001] The invention belongs to the technical field of rainwater lifting, and in particular relates to a rainwater automatic lifting device and a construction method in an underground rainwater pipeline. Background technique [0002] Rain refers to the weather phenomenon in which water vapor condensed in the atmosphere falls to the earth's surface in various ways. Almost all the water vapor in the atmosphere is concentrated in the troposphere. The higher the temperature, the more water vapor the atmosphere can hold, and vice versa. At a certain temperature, when the air cannot hold more water vapor, it is called saturated air. When the water vapor in the saturated air matches the temperature, condensation does not occur, but when the air is supersaturated, excess water vapor is produced and condensation occurs. [0003] When it rains, a large amount of rainwater falls on the road, and the rainwater falls into the underground rainwater pipe through the rainw...

AI Technical Summary

Problems solved by technology

[0003] When it rains, a large amount of rainwater falls on the road, and the rainwater falls into the underground rainwater pipe through the rainwater grate on the road. If it rains for a long time, it is easy to cause the rainwater pipe to overflow, so that the rainwater in the underground and in the pipe will rise, and the The road is submerged, and a large amount of rainwater accumulates on the road, so that the driver cannot observe the road surface well, which increases the danger of the driver driving the vehicle, which is not conducive to people's safety, and a large amount of rainwater accumulates together, and the rainwater is difficult to evaporate , is not conducive to people walking on the road
