Ecological evaporation overflow pool

Abstract

The invention belongs to the technical field of water treatment, and particularly relates to an ecological evaporation overflow pool which comprises a drainage section, an energy dissipation section, a water storage and seepage section and an overflow section which are connected in sequence, the drainage section, the energy dissipation section and the water storage and seepage section are arranged in sequence from high to low, and the overflow section is not higher than the highest point of the water storage and seepage section. The drainage section, the energy dissipation section, the water storage and seepage section, the overflow section and other functional zones are divided, the energy dissipation effect on rainwater pressure is greatly improved, rainwater drainage is accelerated through the evaporation effect, the seepage effect and the water retention effect of vegetation in the water storage and seepage section, the deposition amount is greatly reduced, and a large amount of dredging and maintenance labor cost is saved; meanwhile, by means of ecological greening in the water storage and seepage section, the proposed highway and the surrounding landscape are integrated, and the strong landscape coordination effect is achieved.

Description

technical field [0001] The invention belongs to the technical field of water treatment, and in particular relates to an ecological evaporation overflow pool. Background technique [0002] In the construction of highways in mountainous areas, in order to save land resources, the line type is generally planned according to the mountains, especially in the terrain where the upstream is a valley and the downstream is an open land. It is difficult to drain water. To solve the above problems, the existing technology generally adopts an evaporation pool structure for water collection. Relying on evaporation to drain water, this type of evaporation pool is mostly a regular rectangle, and the walls of the pool are mostly rubble or concrete, and the bottom of the pool is mostly dry rubble. There are some disadvantages in this type of evaporation pool, 1. The energy dissipation of rainwater pressure The effect is poor, and it has a limited effect on reducing the erosion of the land dow...

[0002] In the construction of highways in mountainous areas, in order to save land resources, the line type is generally planned according to the mountains, especially in the terrain where the upstream is a valley and the downstream is an open land. It is difficult to drain water. To solve the above problems, the existing technology generally adopts an evaporation pool structure for water collection. Relying on evaporation to drain water, this type of evaporation pool is mostly a regular rectangle, and the walls of the pool are mostly rubble or concrete, and the bottom of the pool is mostly dry rubble. There are some disadvantages in this type of evaporation pool, 1. The energy dissipation of rainwater pressure The effect is poor, and it has a limited effect on reducing the erosion of the land downstream of the pond; 2. The seepage structure of the dry rubble depends entirely on the seepage between the cracks, the seepage channel is narrow, and the seepage time is long. Evaporative drainage takes a long time, and the drainage effect is basically not achieved in the rainy season; 3. The pool is easy to silt in the rainy season, and the frequency of manual dredging is high; Difficult construction on steep slopes
