Concealed rainwater collection system arranged below ground prefabricated cover plate

Abstract

The invention discloses a concealed rainwater collection system arranged below a ground prefabricated cover plate. The system comprises a collection device arranged below the prefabricated cover plate and a drainage device connected with the collection device, wherein a trough which is provided with an opening towards the direction of the prefabricated cover plate is formed in the collection device; and the drainage device is respectively connected with the trough of the collection device and an urban underground rainwater discharging pipeline. The invention has the advantages that: the concealed rainwater collection system arranged below the ground prefabricated cover plate does not influence the ground function, is concealed, waterproof and high-efficiency, and the like. The concealed rainwater collection system has flexible extensibility and is suitable for an underground structure which has high requirement on surface water and rainwater prevention and of which the top plate is needed to be provided with a manhole.

Description

technical field [0001] The invention relates to a rainwater collection system, in particular to a concealed rainwater collection system arranged under a ground prefabricated cover plate. Background technique [0002] With the economic development of society, urban construction is no longer limited to the construction on the ground. The development of underground construction also followed. With the development of facilities such as subways, underground common trenches, cable trenches, and large-scale underground sewage plants, the development of urban underground construction is also advancing by leaps and bounds. [0003] In many cases, the roof of underground buildings or structures needs to reserve upper and lower access manholes for maintenance, equipment hoisting, etc. When the size of the manhole is too large to be covered by non-general shaped cover plates, strip cover plates can only be used for splicing Covering to prevent underground structures from affecting the...

AI Technical Summary

Problems solved by technology

However, in rainy weather, the prefabricated cover panels currently used in the industry cannot effectively prevent rainwater from converging and infiltrating into the underground structure, which will lead to water accumulation in the underground structure

In the case of heavy rainfall, it will cause serious water accumulation in the underground structure.

If the accumulated water cannot be discharged for a long time, it will cause adverse or inconvenient effects on the underground structure itself, interior decoration, equipment pipelines, personnel activities, etc.

According to the survey, many underground structures that only use ordinary prefabricated cover plates cannot effectively prevent rainwater from entering and cause internal water accumulation, which seriously affects normal use
