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

Embodiment Construction

[0022] Such as figure 1 , 2 As shown, a specific embodiment of a concealed rainwater collection system related to the present invention is set under the prefabricated cover plate 210 of the ground 200, including a water interception device 110, a collection device, a drainage device 130 and ancillary structures.

[0023] Wherein the water interception device 110 is set along the periphery of the underground structure shaft (not shown) below the prefabricated cover plate 210, which includes an outer side 112, a bottom side 114 and an inner side (water retaining sill) 116 and surrounds it to form Interception ditch 118. The water intercepting ditch 118 can play the role of intercepting the surface water of the surrounding ground 200, and simultaneously plays the role of a drainage ditch. Some fitting notches 113 are also provided on the inner side of the water intercepting device 110 .

[0024] The water collection device includes a number of launders 120 . The flow channel ...

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...
