Arch type aluminum alloy flood prevention plate

Abstract

The invention provides an arch type aluminum alloy flood prevention plate. The arch type aluminum alloy flood prevention plate comprises a foundation, an upright, water blocking plates and a water stopping device. The upright is fixed to the foundation. The two sides of the upright are provided with vertical insertion slots used for clamping and fixing the arch type aluminum alloy water blocking plates. The water stopping device comprises seal rubber mats which are arranged in the insertion slots, between the arch type aluminum alloy water blocking plates and in the positions where the arch type aluminum alloy water blocking plates making contact with the foundation. The water blocking plates are arch water blocking plates protruding towards the water blocking direction. The bending moment and deformation of the arch type water blocking plates provided by the invention are both much smaller than those of a traditional structure, and stress, sealing water stopping and material saving are facilitated. Multiple arch arrangement is adopted, thus horizontal thrust of adjacent arches to the uprights can be balanced mutually, a multiple arch effect is achieved, additional loads of the uprights are not increased, the stress advantage of the arches is used, and the adverse influence of arch thrust is also overcome.

Description

technical field [0001] The invention relates to a flood control water retaining product, in particular to an arched aluminum alloy flood control plate, which belongs to the technical field of urban flood control. Background technique [0002] Flood control walls refer to water-retaining buildings or water-retaining structures used to ensure the flood control safety of cities, towns and important factories and mines, or to meet other special protection requirements along rivers or coasts (including some seawalls). structure. Traditional flood control walls are all masonry buildings or concrete buildings, such as earth embankments, mortar block stone flood control walls and concrete flood control walls. This type of building occupies a large area, and sometimes it is necessary to demolish and resettle residents and units on the project land in densely built urban areas, so not only wastes land resources, but also has relatively high construction costs. In addition, the tradi...

Problems solved by technology

[0017] As a preference, the plate section adopts a rectangular section, and longitudinal and transverse partitions are arranged in the arch direction, so as to divide the box-shaped water retaining plate into several small chambers, thereby avoiding the arch water retaining plate from being unstable under pressure and ensuring the water retaining The buckling stability of the plate solves the problem of the compression stability of the water retaining plate
