Description
Technical field
Anhui river Riparian Zone bridge pier Scour and Accretion survey calculation method of the present invention, belongs to water conservancy survey speciality, be one kind in river
The method that erosion and deposition is measured and calculates erosion and deposition is carried out in stream at bridge pier.
Background technology
Yangtze River In Anhui Province section is located at THE LOWER YANGTZE VALLEY, above plays Xiusong County section kiln, Xia Qihe counties team of four horses river mouth, river course total length 416km,
Two sides main dike total length is 771km, is famous " golden waterway ", riverine to have Anqing, Chizhou City, Tongling, Hefei, Wuhu, saddle
The important cities such as mountain city, it is densely populated, it is economically developed, it is the important Industrial Corridor in Anhui Province.In January, 2010, State Council formally criticized
It is multiple《Wanjiang Cities band undertaking industrial transfer demonstration section planning》, Wanjiang Cities band is that China implements to promote rise of the central region strategy
Give priority to region, its flood control safety, water supply security and continent beach Living environment safety of human being become particularly important.Due to Three Gorges work
Since journey impounding and operation, incoming water and sediment changes, and Anhui river river regime evolution is more violent, and channel thread swings amplitude
Larger, the change of branch channel diversion sediment diversion is obvious, and continent swale erosion and deposition is frequent, puts shifting on main flow top punching point, and bank slope collapse scope expands
Greatly.According to statistics, Anhui river collapse on the bank is increased at 76 by 59, and at collapse on the bank area total length 418km, wherein middle bar collapse on the bank 16, collapse on the bank is long
Degree 83km, after deducting middle bar collapse on the bank length, two sides collapse on the bank length accounts for total water front 45%.After the water-retention of Three Gorges, downstream river course is in stream
Amount flood peak smoothization, increased periods.The upstream of Three Gorges in 2010 is met with after letting out compared with great flood control, and Anhui river section flood peak is presented flattening, flood
Water increased periods, water level of yangtze river continue about 40 days near flood control warning line, increased tributary flood pressure.
As Anhui river Riparian Zone sand grain is thinner, side slope extremely unstability in two sides builds bridge pier erosion and deposition thereon
Characteristic is extremely complex, and as upland water carrys out the change of husky and periphery side slope, the erosion and deposition near bridge pier is violent in annual change.
The erosion and deposition of bridge pier is measured and described, is conducive to the erosion and deposition to bridge pier to carry out early warning.
Under normal circumstances, the erosion and deposition measurement for carrying out bridge pier is the method using boat measurement, and ship is reached near bridge pier, using super
Echo sounder utilizes fish lead, and the depth of water is measured, and is scaled bed level of the river by relation of the depth of water with elevation, dangerous
Greatly, efficiency is low, and measurement cost is very high.
The content of the invention
In order to solve the above bridge pier measurement problem, the invention discloses one kind in bridge side fixed support to bridge pier erosion and deposition
The method for measuring.
Specifically the present invention is comprised the following steps：
1st, in bridge two sides fixation measuring support and lateral strut；
2nd, using the interspersed steel cable of ring set in lateral strut, and the connection floating canoe on the steel cable of upstream side；
3rd, hang in canoe is floated in water in upstream side, current can drive floating canoe that bridge opening is passed through under bridge；
4th, hooked using rope hose tool in downstream and take upstream steel cable, and downstream vertical steel cable is fixed on into floating canoe using lock
On；
The 5th, floating canoe can be rested on the optional position of bridge pier side by the dragging of two steel cables；
With adjacent bridge pier as border when the 6th, measuring if adjacent bridge pier distance is less than 200m, if adjacent bridge pier distance is more than
200m is then with 200m as border；
7th, along bridge direction, from adjacent bridge pier to tested bridge pier traverse measurement, a section is divided into per 5m；
8th, along river direction, steel cable is gradually discharged from upstream toward downstream, supersonic sounding instrument is entered with the frequency of 1 time per second
Row depth survey, steel cable rate of release are 0.5m per second；
9th, terminate half of measurement when canoe reaches tested one half width of bridge pier, floating canoe is taken off with the vertical steel cable in downstream
Open；
10th, canoe is sling using the vertical steel cable in upstream, moves to opposite side, proceed measurement；
11st, after being all measured, data retrieval is carried out into figure structure；
12nd, multiple measurement results are contrasted, and calculate scour and fill.
Above-mentioned measurement bracket includes horizontal stand and vertical support frame, and horizontal stand stretches out bridge floor not less than 4m, vertical
Frame highly hangs down into bridge floor and bridge pier jointing altitude；
Above-mentioned lateral strut includes bridge floor lateral strut, turning lateral strut and bridge bottom horizontal pole；
It is used for fixes in 3 above-mentioned lateral struts and also secure on the ring set of steel cable bilateral pulling steel wire rope, it is unilateral 3 strands
Pulling steel wire rope to merge becomes the pulley that one steel wire penetrating is fixed in the lateral strut of turning；
It is fixed in measurement bracket to pull wireline winch；
GPS and supersonic sounding instrument are fixed on above-mentioned floating canoe.
The beneficial effects of the present invention is：
1st, the present invention manually need not aboard ship be operated and be obtained with measurement data；
2nd, the method for the present invention improves measurement safety, reduces cost；
Section spacing and the very little of vertical line measurement control can be improve certainty of measurement by the 3, method of the present invention.
