Description

Garage roof drainage and sponge city rainwater collection, purification and utilization organizational system

Technical Field

The utility model relates to the technical field of drainage and sponge urban rainwater purification, in particular to a garage roof drainage and sponge urban rainwater collection, purification and utilization organization system.

Background

The main slope drainage that relies on among the current garage roof drainage technique to the technique of garage roof ponding is solved to the compound mode of design drain bar or drainage french drain, along with the trend of the large-span of garage roof, the roof is more and more complicated to look for the slope, even designed to look for the slope, the job site also hardly realizes, can't realize the drainage at all sometimes. Meanwhile, according to the traditional design, the comprehensive cost is high, the construction period is long, the system reliability is low, and once the node part of the diversion blind ditch is damaged, the system is likely to be paralyzed. In the engineering field, due to the problems of supervision, other procedures and the like, the diversion blind ditches are likely to be damaged at multiple positions without being put into use. Even if the construction is not damaged, the blind ditch is blocked due to the collapse of the backfill soil after the construction is put into use, and then a drainage system fails.

The low-influence facilities of the sponge city on the top plate of the large garage comprise a concave green land, a biological retention facility, a grass planting ditch and the like, which need to be excavated again after backfilling, a cushion layer and a drainage layer are manufactured, a standard-exceeding rainwater overflow well needs to be arranged, and rainwater infiltration and drainage are only considered in the whole system. Several problems will be faced: 1. the rainwater collection and infiltration of low-influence facilities greatly increase the pressure of a drainage system of a top plate of the ground reservoir, which is difficult to drain originally; 2. the construction cost and the construction period are increased;

the plants for planting and greening must be waterlogging-resistant and drought-resistant, and the landscape effect is poor due to the small selection range;

the regulation and storage of rainwater is easy to breed mosquitoes in summer;

because of the greenery patches rate restriction, conventional low influence facility can't satisfy the regulation requirement, need set up the terminal rainwater regulation pond of bulky and carry out the rainwater and collect, only exert the regulation effect, retrieve rainwater low-usage, and poor to rainwater dirt-removing power, easily get into municipal pipe network through the overflow facility.

The siphon drainage mode still has certain protection leaks in the aspects of connection treatment between the drainage plates, connection treatment between the drainage plates and the drainage grooves and the like;

the above method only considers the problem of drainage, and lacks means for controlling the source rainwater.
