Multi-structure combined apron

Abstract

The invention discloses a multi-structure combined apron. The multi-structure combined apron comprises a surface layer structure and a cushion layer structure, wherein the surface layer structure comprises a plurality of splicing units; the splicing units are spliced in the water flow direction; each splicing unit comprises a plurality of concrete blocks arranged in a flexibly spliced mode in thedirection perpendicular to the water flow direction, and a plurality of metal cages filled with stones; the concrete blocks of the adjacent splicing units are staggered in the water flow direction andare flexibly spliced to each other; the metal cages are distributed between every two adjacent concrete blocks in a dotted mode; and the cushion layer structure is arranged at the bottom of the surface layer structure and used for filtering and leveling a foundation surface of the surface layer structure. The requirements of integrity, flexibility, water permeability and surface roughness can bemet simultaneously.

Description

technical field [0001] The present invention relates to a seaman, in particular to a seaman with a combination of multiple structures. Background technique [0002] The damage of water leakage structures is the most common among hydraulic structures. The discharge structure undertakes the work of venting the incoming water from the upstream, and is also scoured by the downstream water flow, especially the high-speed water flow. The damage to itself and the downstream channel caused by the water flow is relatively common. In order to protect the riverbed downstream of the gate and dam from the erosion of high-speed water flow, a sea diffuser is usually installed at the outlet of the stilling tank at the gate and dam, which can effectively offset the residual energy of the water flowing through the stilling tank, and further adjust and diffuse the water flow, so that The flow rate of the water flow out of the stilling pool is reduced to prevent the water flow from scouring an...

Problems solved by technology

The above various forms of sea diffusers cannot fully meet the requirements of "integrity, flexibility, water permeability and surface roughness" at the same time, and each has its own advantages and disadvantages in application.
