Water guide system and construction method applied in sponge city ecological ground system

Abstract

The invention discloses a water guiding system applied to an ecological ground system of a sponge city and a construction method. The water guiding system comprises a water guiding unit composed of multiple water guiding pipes and a water guiding cover used for blocking openings formed in the upper ends of the water guiding pipes; the water guiding pipes comprise the upper water guiding pipes and the lower water guiding pipes, the upper water guiding pipes are provided with multiple lower-end branch pipes which are communicated with the lower water guiding pipes, the openings formed in the upper ends of the upper water guiding pipes are connected with the water guiding cover, and the upper water guiding pipes and the lower water guiding pipes are assembled together to form the water guiding unit. The construction method comprises the steps that the ground is flattened, a natural gravel cushion layer is laid, and after a broken pebble layer is laid, the water guiding system is placed on the broken pebble layer; concrete is poured, the water guiding cover of the water guiding system is taken down when the concrete is not dry, and then multiple drainage grooves are formed; rainwater is gathered in the grooves and flows back to the underground through the water guiding unit, therefore, water can be prevented from running off along the hardened ground, and rainwater infiltration is accelerated to prevent surface water gathering.

Description

technical field [0001] The invention relates to a water guiding system and a construction method, specifically, a water guiding system and a construction method applied in the ecological ground system of a sponge city Background technique [0002] Sponge city refers to a city that can be like a sponge and has good "elasticity" in adapting to environmental changes and responding to natural disasters. When it rains, it absorbs, stores, infiltrates, and purifies water, and "releases" the stored water when needed. and take advantage of it. Under the premise of ensuring the safety of urban drainage and waterlogging, the sponge city maximizes the accumulation, infiltration and purification of rainwater in the urban area, and promotes the utilization of rainwater resources and the protection of the ecological environment. The traditional urban construction model is full of hardened roads. Whenever there is heavy rain, it mainly relies on "grey" facilities such as pipes, canals, a...

Problems solved by technology

Whenever there is heavy rain, it mainly relies on "grey" facilities such as pipes, canals, and pump stations to drain water. The main planning and design concepts are "quick drainage" and "end-centralized" control. Rainwater is mainly drained through drainage facilities and cannot penetrate into the ground. It will cause waterlogging every time it rains, and the drought and flood will turn sharply, which does not meet the requirements of sponge city construction
