Problems solved by technology

But at the same time, there are also great defects: the film formed by the chemical agent cannot reduce the absorption of solar energy by the water body, but inhibits evaporation while inhibiting the heat consumption of the water body by evaporation. In the uncovered water surface, the higher water temperature will lead to evaporation. increase; the effect of wind and waves often makes the film layer unable to maintain a good state, and the evaporation suppression effect is unstable and has too many limitat

Embodiment Construction

[0014] The method of water-saving lightweight concrete to suppress water surface evaporation is: use prefabricated wind-resistant, impermeable, frost-resistant, and anti-aging water-saving lightweight concrete slabs or blocks, floating on the water surface, the thickness of the slab or block is 3cm to 9cm, and the length And the width is controlled between 0.5 ~ 3m respectively. During prefabrication, the reinforcement is reinforced and exposed into a ring, connected to each other, and the connecting rope is fixed horizontally on the side of the pool (reservoir, lake, etc.). If the water area is small, cover the water surface completely; if the water area is large, cover 60% to 85% of the water surface, and divide the water surface of large pools (reservoirs, lakes, etc.) into grids, and place some lightweight concrete in each grid slab or block, and a vertical pile is driven downward in the middle of the square, and the pile is connected with the light concrete slab or block conn

Abstract

The invention provides a water-saving light concrete method for restraining water surface evaporation. In the method, light concrete slabs or blocks which can float on water are partially or completely placed on the water surface. The prefabricated water-saving light concrete slabs or blocks can resist wind, seepage, freezing and ageing, the thickness of the light concrete slabs or blocks is within 3 to 9cm, and the length and width are respectively controlled within 0.5 to 3m; when in prefabrication, steel bars are added and exposed to form ring shapes, all the light concrete slabs or blocks are connected by ropes, and the connection ropes are fixed on vertical piles beside a water pool (a reservoir) or in water. The invention belongs to a physical covering method, has the advantages of simple operation, low price and low maintenance cost, can resist wind, seepage, freezing and ageing, and is particularly applicable to evaporation reducing and water saving for the water surfaces of the water pool, the reservoir, a lake and the like.
