Rainwater collecting pool and construction method thereof

Abstract

The invention discloses a rainwater collecting pool and a construction method thereof. The rainwater collecting pool comprises a flow abandoning pool and a modular pool; a flow abandoning pool filterscreen is arranged at the middle part of the flow abandoning pool; the flow abandoning pool is divided into a dirt filtering area and a precipitating area by the flow abandoning pool filter screen; one end of the flow abandoning pool is a water inlet, and the other end of the flow abandoning pool is a water outlet; the water outlet is connected with a water outlet pipe; the water outlet pipe is connected with the modular pool; water storage grid layers are uniformly distributed in the modular pool; inspection wells communicating with the water storage grid layers are symmetrically arranged atthe two ends of the water storage grid layers; dirt discharge pumps are arranged at the bottoms of the inspection wells; one inspection well is connected with the water outlet pipe; a sand settling pool is arranged at the bottom of the other inspection well; and an overflow port is formed in the side wall, near one end of the sand settling pool, of the modular pool. The rainwater collecting pool can effectively collect and store rainwater; and through wide application of rainwater collection and utilization, rainwater is retained or infiltrated underground, so that the displacement is reduced,the urban flood disaster threat is relieved, underground water is supplemented, the water environment is improved, and the ecological environment is repaired.

Description

technical field [0001] The invention relates to a construction method, in particular to a rainwater collection pool and a construction method thereof, which are mainly applicable to rainwater collection and utilization in residential quarters, industrial parks, squares and workshop areas, and belong to the technical field of rainwater collection and utilization. Background technique [0002] Generally speaking, the construction process of traditional reinforced concrete rainwater collection tanks is complicated and there are many procedures (excavation of foundation pit, foundation pit support, cushion construction, steel bar binding, formwork installation, concrete pouring, maintenance, formwork removal, waterproof construction, Foundation pit backfill, etc.), due to the limitation of its own construction technology, the construction period is long, the exposure time after foundation pit excavation is long, the requirements for foundation pit support are high, and safety acc...

[0002] Generally speaking, the construction process of traditional reinforced concrete rainwater collection tanks is complicated and there are many procedures (excavation of foundation pit, foundation pit support, cushion construction, steel bar binding, formwork installation, concrete pouring, maintenance, formwork removal, waterproof construction, Foundation pit backfill, etc.), due to the limitation of its own construction technology, the construction period is long, the exposure time after foundation pit excavation is long, the requirements for foundation pit support are high, and safety accidents such as foundation pit collapse are prone to occur during construction. Construction is affected by seasons, The influence of the weather is greater; due to the requirements of the structure and construction technology, there are high requirements for the conditions of the construction site. Due to the large self-weight, the requirements for the bearing capacity of the foundation are high, and uneven settlement is prone to occur, resulting in the cracking of the reinforced concrete pool Leakage occurs; earthquake resistance and crack resistance are poor, and leakage is easy to occur; once the concrete structure is damaged, it is difficult to repair, reinforce, and reinforce; materials cannot be recycled after being discarded, causing secondary pollution to the environment; the pool surface bears low load and cannot Secondary utilization; the internal structure of concrete is relatively rough, easy to attach impurities, and easy to breed algae and fungi, which is not conducive to ensuring stable water quality
