Overflowing slag collecting weir for water conservancy and hydropower engineering and construction method thereof

Abstract

The invention relates to an overflowing slag collecting weir for water conservancy and hydropower engineering and a construction method thereof, and belongs to the technical field of design and construction of water conservancy and hydropower engineering buildings. The overflowing slag collecting weir comprises a weir body, wherein the weir body comprises a river body and river banks on the two sides of the river body; a protective net plate is erected in the river body; end plates are arranged on the two sides of the protective net plate; the plate surfaces of the end plates are perpendicularto the plate surface of the protective net plate; the end plates are attached to the side walls of the river banks; loading net boxes are arranged on the end plates in a sliding mode; lifting assemblies for driving the loading net boxes to move in the vertical direction are arranged on the river banks; a flat laying table is laid at the bottom of the river body; a translation net plate is arranged on the protective net plate; a driving assembly is arranged on the protective net plate; a blocking net plate is arranged at the upstream end of the protective net plate in the river body; and moving assemblies used for driving the blocking net plate to ascend and descend in the vertical direction are arranged on the river banks. The overflowing slag collecting weir has the advantages that stoneslag in an overflowing protection structure can be conveniently cleaned, and then the difficulty of slag collecting and the danger coefficient are reduced.

Description

Technical field [0001] The invention relates to the technical field of design and construction of water conservancy and hydropower engineering buildings, in particular to an overcurrent slag collecting weir used in water conservancy and hydropower projects and a construction method thereof. Background technique [0002] At present, in water conservancy and hydropower projects, dam abutment slopes or river bank slopes are excavated. The current general technology is to set up a slag collecting platform at the foot of the river bank slope to collect gravel, but due to the steep slope, the slag collecting platform collects gravel Limited, excavated gravel will enter the river course and be carried downstream by the water, causing river siltation and soil erosion. At the same time, the construction of the bank slope foot is difficult to collect. Therefore, the Chinese Patent Authorized Announcement No. CN104947630B discloses an overflow slag collecting weir for water conservancy and ...

Problems solved by technology

[0003] However, the above-mentioned invention has a disadvantage in that, although the over-current protection structure can effectively block the flow of gravel in Hanoi to the downstream, after a long time, a large amount of gravel will accumulate in the over-current protection structure, which is likely to occur in a large amount. After the accumulation, the over-current protection structure will be blocked, causing the water flow to fail to flow normally, and what's more, the over-current protection structure will be washed away

Due to the turbulent water flow at the overflow slag collection weir, it is very dangerous to salvage and clean up manually. If you drive a salvage vehicle to salvage, it is easy to cause landslides due to the soft soil on the shore
