Description
Technical field
The invention belongs to hydraulic engineering field more particularly to a kind of structures or system for preventing and treating Canal in Loess Area groove channel erosion.
Background technique
In the widely distributed loess in the provinces such as the Shanxi in China, Shaanxi, Gansu, Ningxia, Qinghai, the Inner Mongol, Henan, vegetation is covered
Lid rate is low, and soil property is more loose, has strong water sensitivity.It is influenced by monsoon climate, Canal in Loess Area precipitation is concentrated, and is mostly sudden and violent
Rain is easy to produce groove channel erosion under runoff effect, soil erosion occurs, cause region breaking topography, ravines and guillies criss-cross, produces item
Part and the deterioration of the ecological environment, Ecological Safety Situation is severe, becomes and restricts the great of Canal in Loess Area society and economy sustainable development
Strategic issue.Rill erosion is formed under flow dynamic and self gravity synergy, and rill erosion is according to the form and differentiation of generation
Process is divided into the different phases such as rill erosion, shallow gully erosion, groove channel erosion.Loess channel and Zhigou often have landform gradient
Greatly, the features such as ditch wide direction is narrow, catchment area is limited, traditional silt arrester is in middle and upper reaches channel and Zhigou sediment trapping alluvial plain efficiency
It is low, it the problem of deficiency in economic performance, studies light-duty dispersibility and blocks deposit technique, change that concentrate accumulation before the dam of Littoral Barrier be channel point
Cloth accumulation realizes the economic efficient utilization intercepted with water resource of silt in basin, is of great immediate significance.
Summary of the invention
The present invention proposes the soft dam system of becoming silted up certainly for being different from traditional design theory aiming at the problem that groove channel erosion of Canal in Loess Area
System realizes the separation of water sand using the permeable siltation system of channel, isolated water flow is excreted to downstream security area by siphonage
Domain, silt are then formed in the case where water sand shunts and washes away siltation effect in section channel repeatedly from the soft dam that becomes silted up, and change channel ratio of slope with this,
Slow down groove channel erosion and soil erosion.
The technical solution of the present invention is as follows: it is a kind of for prevent and treat Canal in Loess Area groove channel erosion from the soft dam system of becoming silted up, including it is saturating
Water siltation system, siphon drainge system.Permeable siltation system includes plastic blind-ditch, geotextiles, excavates groove in the bottom of trench of channel,
Place multiple plastic blind-ditchs in groove, the cross section of plastic blind-ditch is rectangle, geotextiles is wrapped up outside plastic blind-ditch, in channel
Water sand separates after silt carrying flow flows through permeable siltation system, and in the base slope of channel, erosion and deposition is formed from the soft dam that becomes silted up silt repeatedly；Siphon
Drainage system includes shunting pond, cover board, discharge siphon, and the water outlet of plastic blind-ditch is connected to pond is shunted, and shunts the top in pond
Equipped with cover board, the side wall for shunting pond is equipped with aperture, the height of aperture lower than the top 30cm or more for shunting pond, the diameter of aperture with
The caliber of discharge siphon is identical, and the water inlet of discharge siphon, which is extend into, to be shunted in pond, and the water outlet of discharge siphon passes through
Downstream security region is placed on after shunting the aperture of pond side wall.
Further, the depth in the shunting pond is 2m~4m, and the length and width for shunting pond are 0.8m~1m.
Further, the discharge siphon in the siphon drainge system be 1 or more, caliber be 200~
500mm。
When heavy rainfall occurs, runoff enters channel after washing away slope surface, and silt carrying flow is accumulated in channel, works as silt carrying flow
When flowing through the permeable siltation system for soft dam system of becoming silted up certainly, water flows into plastic blind-ditch through geotextiles, and it is laggard that water flows through plastic blind-ditch
Enter to shunt pond, when the water level in shunting pond exceeds the aperture of shunting pond side wall, drainage procedure occurs, siphonage starting, draining
The water shunted in pond is excreted to downstream security region by siphon pipe, and due to siphonage, the silt shunted in pond can be by draining rainbow
Suction pipe is sucked out, and sediment siltation will not be occurred by shunting pond.In channel water sand separation after sediment siltation channel base slope, rainfall and
Runoff effect repeated, and silt washes away siltation in the channel of water sand shunting section repeatedly and forms the wide slow soft dam that becomes silted up certainly.
With increasing from the soft height of dam degree that becomes silted up, the permeability of permeable siltation system is gradually decreased, and silt carrying flow can more cross earlier shape
At from the soft dam of becoming silted up, be gradually increased the width from the soft dam that becomes silted up.The orographic condition for changing channel after being formed from the soft dam that becomes silted up, slows down ditch
The ratio of slope in road reduces the flow velocity of water flow, reduces the erosion to channel and washes away, avoids soil erosion.
The contents of the present invention are combined to explain advantages of the present invention as follows:
1. by permeable siltation system combined with siphon drainage technology in the way of realize that water sand separates, water is transported to down
Safety zone is swum, sediment siltation is formed in channel base slope from the soft dam that becomes silted up, and silt is not only kept but also is fully utilized.
2. slowing down the ratio of slope of channel using the orographic condition for changing channel from the soft dam that becomes silted up of ladder-type distribution, reducing water flow
Flow velocity, reduce to the erosion of channel and wash away, while avoiding soil erosion.Exempt from power from silt process, saves a large amount of people
Power material resources.
3. siphon drainage has dredging effect, can remove into the silt shunted in pond, to avoid silting causes to shunt
Lose effect of catchmenting in pond, it is ensured that effective work of system.
