Problems solved by technology

One of the main flexible berm structures currently used at home and abroad is the gabion structure, and its disadvantage is that the consumption of stones is too large; the other is a row of prefabricated concrete blocks connected by metal hinges or connected in series by ropes, and its disadvantages are The metal hinges have corrosion problems, and the rope is easily broken by friction with the surrounding area under the action of water flow

Embodiment Construction

[0018] The concrete is poured directly in the form of blocks or the prefabricated concrete block 1 is cemented and riveted on the geogrid 2 (or geonet) to form a flexible row. The geogrid (or geonet) should be controlled within the section of the block. Middle or bottom; single concrete block size: 40cm×40cm×4cm; single block row size: 2.5m×2.5m; block spacing 2cm; row spacing 5cm.

[0019] The row bodies are connected from top to bottom by the hook 4 embedded in the block along the direction of water flow. The hook is made of galvanized round steel with a diameter of 6mm, which looks like a tunic collar buckle, and the geogrid (or geonet) ) are directly connected in the form of buckles or thermally welded; the space between the blocks is filled with the filter material 5 that supports plant growth.

[0020] Reserve a through hole 3 on the concrete block, and use the willow anchor 9 and the anti-corrosion metal anchor 10 passing through the through hole to fix the row body; th...

Abstract

The invention relates to a soft platoon made up of concrete block and civil gratings or civil meshes, which has function for protecting the bank and slope. The invention pours the concrete directly or adheres the preprocessed blocks and fixes them on the civil gratings or the civil meshes with type of block, thus it guarantees the durability and the security of the platoon. The platoons are connected together by the hook embedded in the block or the civil gratins and the civil meshes are connected or welded together with clamp type; the concrete can be processed into the one with low alkali density and with connected aperture, which can be filled with soil for the plant to grow, then it is formed into green project which has protection function to bank.

Description

Technical field [0001] The invention relates to a flexible bank protection row, in particular to a flexible row body which is composed of a concrete block and a geogrid (or geonet) and has the function of bank protection and slope protection. Background technique [0002] In order to prevent the bank slope of the river from being washed by the river, embankments are generally built on both sides of the river. At present, the embankments widely used at home and abroad are mainly rigid embankments constructed of reinforced concrete or masonry. This type of embankment has high requirements on the bearing capacity of the foundation, and usually requires a large amount of excavation and engineering. The flexible berm has low requirements on the bearing capacity of the foundation, strong anti-seismic and anti-subsidence damage capabilities, and has a certain degree of self-healing ability. One of the main flexible berm structures currently used at home and abroad is the gabion st...
