Embodiment

[0021] This example takes the Longtan Reservoir in Guang'an City, Sichuan Province as an example to illustrate:

[0022] During specific construction, such as figure 1 As shown, a trash rack 5 is set at the front of the water intake 1 (facing the water) to block floating dirt in the reservoir; a deep water gate 13 is set behind the trash rack 5 for deep water intake of the reservoir; behind the deep water gate 13 Layered water intake stacking gates are set, and layered water intake is realized by controlling the height of the stacking beam gates; a maintenance gate 7 is installed at the end of the maintenance gate hole 3 for maintenance of the gate hole and downstream buildings.

[0023] The implementation process of the present invention is as follows:

[0024] A trash rack 5 is arranged at the front portion (facing the water) of the water intake 1 to block floating dirt in the reservoir.

[0025] When the downstream water supply demand is domestic water supply, ensure that...

Abstract

The invention discloses a water intake constructing method and structure considering both agricultural irrigation and living water supply. The method includes: a deep water intake gate hole 10 is formed in the bottom of a water intake, and a deep water gate 13 is disposed at the deep water intake gate hole 10; a stop log gate is disposed on the upper portion of the water intake 1, and a service gate hole 3. The water intake constructing method and structure considering both agricultural irrigation and living water supply has the advantages that when reservoir downstream has comprehensive requirements of agricultural irrigation and living water supply, appropriate water temperature layer reservoir water can be provided for agricultural irrigation, and deep reservoir water with good water quality can be provided for living water supply; perfect combination of reservoir ecology protection and engineering economic benefits is achieved, and the defects of tradition water intakes are overcome.

Description

technical field [0001] The invention relates to a construction method and structure of a water intake taking into account both agricultural irrigation and domestic water supply, and belongs to the technical field of water conservancy and hydropower engineering. Background technique [0002] In the construction of water conservancy projects, reservoirs are mainly used for agricultural irrigation and domestic water supply. Agricultural irrigation water has strict requirements on the temperature of agricultural irrigation water. If the water temperature is low, it will directly affect the growth of crops and cause crop yield reduction. Therefore, agricultural irrigation water has higher requirements on water intake temperature. Generally, stratified water intake is adopted, and the surface water of the reservoir is used as much as possible to ensure the water intake temperature. Domestic water does not have high requirements on water temperature, but has higher requirements on...
