The invention discloses a rainwater collecting and recycling construction method applied to a
sponge city. The construction method includes the steps of step 1,
site selection of a
water storage area;step 2, foundation pit treatment; step 3, reservoir establishment; step 4, circulating
system establishment; and step 5, foundation backfilling and ground surface treatment. According to the rainwater collecting and recycling construction method applied to the
sponge city, the construction method is reasonable in design, clear in construction procedure, simple and reliable in construction steps,proper in step connection arrangement, high in quality, and capable of effectively guiding urban rainwater to permeate into the ground, so as to achieve the effect of fully recycling the rainwater, accelerating rainwater infiltration, and preventing water accumulation on the
road surface. Meanwhile, the rainwater can be effectively percolated, purified, collected and conserved, the
water quality is improved, an underground stored
water source is improved, and
surface water is conveniently recycled, which increases the
water source utilization rate, and supplements
urban water; and different water qualities are obtained through different treatment
modes and applied to different aspects, so that the
surface water is more reasonably and thoroughly utilized, and rainwater resource utilizationand
ecological environment protection are promoted.
