Abstract
This invention is a method of how to dredge waterways in the more sand river. It features are: On the riverbed take the main river trough as the center line, use nature slop of river course and its drop, to build the artificial temporary long dike along river's bank by to use dike-units. On the upper reaches of this dike, use dike-units to from an artificial temporary long dike it traverse with the river.
Description
Affiliated technical field
The present invention relates to the method that a kind of many river sands training of river channel is administered, belong to training of river channel and administer the hydraulic engineering field.
Background technology
The Yellow River downstream channel, riverbed are higher than ground, two sides, come the husky luffing of water very big, the kind silt in river course, apt to change, and flood control is administered has special difficulty.The Yellow River downstream channel generally exceeds back of the body ground, river 3-5m at present, up 10m, and still continuing aggradation, and 0.05-0.1m is raised in alluvial every year on average, and therefore, the Yellow River is called " hanging river ".Simultaneously, in recent ten years, the Yellow River water yield continuous decrease, the average minimizing for many years of water yield ratio is more than 30% since 1986.Along with the exploitation of the Huanghe valley is administered, water supply volume is in continuous increase, and the main stem alluvial increases the weight of, and " hanging river " situation is further aggravated, particularly wide section, the river gesture is gone around changeable, and the main flow swing is frequent, is easy to occur " Yokogawa ", " tiltedly river ", jeopardize dyke safety, not only great flood has the possibility of determining and overflowing, and middle Chang Hongshui also has the danger of bursting, and guarantees that the flood control safety difficulty is very big.And Sedimentation Problems is the core of general plan of harnessing the Yellow River.In quite over a long time, the Yellow River middle and lower reaches will be fully-loaded streams, and the improvement exploitation of the Yellow River must be based upon on this basis.
Summary of the invention:
The purpose of this invention is to provide the method that a kind of many river sands training of river channel is administered.This method can desilting voluntarily under the water yield of stream constantly all the year, the problem of avoiding the riverbed to raise because of silt alluvial effectively.
The technical scheme that realizes the object of the invention is:
The method that a kind of many river sands training of river channel is administered is characterized in that: utilizing the river channel natural gradient and drop, is center line with the major trough on the riverbed, constructs manually causeway temporarily with the road following current along the river of fill unit; At the upstream end of this artificial interim causeway, construct and river course artificial interim causeway crosswise with the fill unit.
The method that described a kind of many river sands training of river channel is administered is characterized in that: the end, upstream of the artificial interim causeway that both sides road following current is along the river constructed is mounted with under water and prevents that river from washing away the soft fascine mattress on described interim river levee basis.
The method that described a kind of many river sands training of river channel is administered, it is characterized in that: the square flexible water bag of high-strength and long with fills with water is made the fill unit.
The method that a kind of many river sands training of river channel of the present invention is administered does not change former sectional area in river course and flood discharge run-off.Desilting voluntarily under the water yield that flows constantly all the year, can withdraw from artificial interim causeway rapidly flood period, builds up the flood fighting small dike rapidly on former wide river levee, increases the flood fighting discharge capacity in river course.
The method that a kind of many river sands training of river channel of the present invention is administered by constructing artificial bund, concentrates on major trough with river and flows, the river of equal flow is flooded, increase flow velocity, make the river flow velocity, cause the riverbed major trough to sink greatly to the silt that can wash away in the major trough.This method can solve the problem that the wide river course channel aggradation is raised effectively.The length of artificial interim causeway needs according to sand surfing and the landforms comprehensive condition in riverbed is decided through consultation.Both sides road the following current along the river and end, upstream of the artificial interim causeway built is mounted with soft fascine mattress under water is in case the basis that current scour should artificial interim end, causeway upstream.This method has that feasibility is strong, the advantage of small investment, easy construction, under the situation that the suitable especially present the Yellow River water yield reduces day by day, removes the silt alluvial, solves the difficult problem that the riverbed is raised.

Embodiment
Many river sands river course that present embodiment is introduced is dredged the method for Ling Zhili and is used the applicant's multi-functional Flood-control bags of SEPARATE APPLICATION utility model patent once, and number of patent application is: ZL 03226730.4,03207537.5 is as the fill unit.The length of the square flexible Flood-control bags of proposed recommendations high-strength and long be 1.5 meters, wide be that 1 meter, height are 1 meter.The vessel innermost layer of Flood-control bags uses fluid-tight PE film, PVC film or rubber membrane, and it is the WARP-KNITTING of high tensile force intensity that skin has one or more layers at least.During use, on the riverbed, be center line with the major trough, both sides are numerous above-mentioned Flood-control bagses, with the mode multilayer of the wall of laying bricks interconnect, overlapping, connect the artificial interim causeway of the globality that is interconnected to road following current along the river and builds with the frenulum setting fastening between the adjacent up and down Flood-control bags.At the upstream end of this artificial interim causeway, still use above-mentioned Flood-control bags as the fill unit, be interconnected to the artificial interim causeway of building crosswise with the river course.Like this, in the river regulation section, river concentrates in the major trough and flows, and the river water level of equal flow is improved, and flow velocity increases, and reaches the silt that washes away in the major trough, the purpose that the riverbed major trough is sunk.The dike of both sides road following current along the river and the artificial interim causeway built is decided apart from can be taken when holding silt under the arm the water level of flow velocity by the flow that can make river, flow velocity.Both sides road the following current along the river and dike height of the artificial interim causeway built will be higher than the major trough inland river water surface.The length of artificial interim causeway is decided through consultation according to the landforms information summary that washes away needs and riverbed.Both sides road the following current along the river and end, upstream of the artificial interim causeway built is mounted with soft fascine mattress under water is in case the basis that current scour should artificial interim end, causeway upstream.Only need when not using the Flood-control bags seal cover is turned on, emit the filling water in the Flood-control bags, folding storage is in order to using next time.
When flood-fighting, also can be used to construct artificial interim river levee in order to flood diversion.
