Overflow water drainage integral type sluice weir

Abstract

The invention discloses an overflow water drainage integral type sluice weir which comprises a weir body, wherein the weir body is enclosed by two side walls and a base plate; an overflow water blocking wall is arranged on the base plate; and a water drainage hole is arranged in the overflow water blocking wall. The overflow water drainage integral type sluice weir disclosed by the invention realizes the functions of waterflood overflow and water drainage by an overflow water blocking wall structure; a water drainage pipe is controlled by a sluice valve and is convenient for operation; a power eliminating pool is arranged in the front of a power eliminating ridge so as to improve the energy eliminating effect; and an integral type waterflow adjusting structure is provided for items of water conservancy, municipal administration and the like. The overflow water drainage integral type sluice weir has higher applicability on a small and medium waterflow structure; meanwhile, a spillway is not viewed during waterflood overflow, the water surface keeps relatively complete and static, the breast wall has a favorable blocking effect on water floating sundries and is convenient for cleaning; and the relative hiding of the power eliminating pool has a favorable inhibiting effect on waterflood overflow noise.

Description

technical field [0001] The invention relates to a gate and weir, which belongs to the field of water conservancy engineering, and more precisely relates to a gate and weir integrating water discharge and overflow. Background technique [0002] Spillways are divided into normal spillways and extraordinary spillways according to flood discharge standards and operating conditions. The former is used to vent design floods, and the latter is used to vent extraordinary floods. According to its location, it can be divided into riverbed spillway and bank spillway. The riverbed spillway overflows through the dam body. According to the structural form, the bank spillway can be divided into: ① positive channel spillway. The discharge chute is perpendicular to the overflow weir, and the water flow through the weir is in the same direction as the axis of the discharge chute. ②Side channel spillway. The overflow weir is roughly arranged along the contour line. After the water flows f...

Problems solved by technology

[0003] In the design structure of existing water conservancy projects, the spillway and the water outlet are generally set at a certain position in a staggered position. Such a design structure, whether it is in the process of foundation excavation or construction, has a large amount of engineering, and it can be said that it belongs to two Engineering projects; more importantly, it is difficult to carry out unified and standardized construction for the two projects, the operation and management are scattered, the engineering cost is high, and the maintenance cost is also high
