Description

Ecological joint body for river course slope protection for flood control and drainage

Technical Field

The utility model relates to river course slope protection engineering, in particular to an ecological clamping body used for river course slope protection for preventing and draining flood.

Background

River course revetment refers to the general term of various paving and planting on a slope in order to prevent the river course side slope from being washed. The river channel has good functions of flood diversion and drainage, and needs dredging and bank slope protection, river sections where bridges are located, and river bank concave banks are gradually washed by water flow, so that river banks can be continuously collapsed. In order to protect the safety of bridges and embankments, protective buildings need to be built on the concave bank. In addition, when the river flow direction changes due to the arrangement of bridges and the farmland and villages are endangered by scouring the river bank, protective buildings need to be built on the river bank. Such buildings are often also referred to as revetments. The form of the revetment has direct protection and indirect protection. The direct protection is to directly reinforce the river bank side slope to resist the washing and panning of water flow. The concrete is usually poured, riprap, dry rubble, grouted rubble, gabion, tip bundle and the like. The indirect protection is suitable for river sections with wider riverbeds or larger protection lengths, and can build spur dams, tailgates, check dams and the like to lift water flow away from river banks.

The function of slope protection can be divided into two categories: (A) the protective layer is only a weather-resistant and erosion-resistant slope protective layer, and the protective layer does not bear lateral soil pressure, such as sprayed concrete slope protection, lattice frame vegetation slope protection, vegetation slope protection and the like, and is only suitable for gentle and stable slope without slide worry. (B) The retaining slope with anti-sliding capability can be roughly divided into: (a) rigid self-weight retaining walls (e.g., masonry retaining walls, gravity retaining walls, wall-leaning retaining walls, cantilever retaining walls, buttress retaining walls), (b) flexible self-weight retaining walls (e.g., snake-cage retaining walls, frame-strip retaining walls, stiffened retaining walls), (c) anchor-pull retaining walls (e.g., anchor-pull grid-beam retaining walls, anchor-pull row-pile retaining walls).

The problem that current river course general bank protection method exists:

1. some river courses are desilted, slope protection construction is not carried out, silt is temporarily piled to both sides river bank, and the time is long, and in addition rain wash and gravity subside, slowly collapse again and flow in the river course, have raised the riverbed.

2. Some river channels are desilted, and adopt high-pressure squirt to strike silt and become mud and flow into low reaches, and this part river channel is desilted, and low reaches still have some deposits, have raised the low reaches riverbed, are unfavorable for the increase flow cross-sectional area of totality.

3. Generally, cofferdams are built firstly, then water is pumped, earth and stone are excavated to build a slope protection foundation, then stone is built to protect the slope, or concrete is poured to protect the slope, so that the cost is too high, and the construction time is limited by the season and the rich water period.

4. Generally, square bricks, hexagonal bricks, grass planting bricks and the like are paved, water can directly wash soil through gaps among the bricks and brick holes, temporary strong and continuous scouring force caused by flood is not resisted, and the revetment is easily damaged, so that the protection of the river levee is further lost, and the river levee collapses and even breaks.

5. And nylon meshes, metal meshes and stones are added, so that nylon can be aged and lose strength, and metal can be rusted and lose strength, thereby losing the fixing effect.

In a word, river bank protection engineering is an engineering measure for protecting river banks from water flow and wind wave invasion and scouring. The construction material type mainly includes cast-in-place concrete revetment, block stone revetment, concrete block revetment, permeable pile revetment, turf ecological revetment and the like. Although the cast-in-place concrete revetment is firm and good in integrity, the cost is high due to cofferdam water pumping construction, the cast-in-place concrete revetment can crack and permeate water due to expansion caused by heat and contraction caused by cold, the anti-scouring capability is weakened, and the cast-in-place concrete revetment also has the defects that the construction is inconvenient and the construction cannot be carried out at a high water level. The stone revetment has the advantages of local materials, simple and flexible construction, adaptation to riverbed deformation, staged implementation, gradual reinforcement and the like, but the stone revetment has high cost and consumes a large amount of manpower and material resources, the stones are not high in lap joint integral strength, and the stone revetment is not suitable for environmental protection requirements; the concrete block revetment is mainly used for stabilizing dikes and dams of river channels and protecting wind waves on the banks; the permeable pile dam has a certain effect of slowing down flow and silt and is only suitable for shallow water flow and slow positions; the turf ecological revetment is mainly used for short flood time, small flow speed and waves, small application range and small flow direction on a bank slope basically parallel to a river bank.
