Description
Technical field
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 for carrying out erosion and deposition measurement at bridge pier and calculating erosion and deposition.
Background technology
Yangtze River In Anhui Province section is located at THE LOWER YANGTZE VALLEY, above rise Xiusong County section kiln, the counties Xia Qihe team of four horses river mouth, river overall 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, 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 variation of branch channel diversion sediment diversion is apparent, and continent swale erosion and deposition is frequent, puts shifting on mainstream top punching point, bank slope collapse range expands
Greatly.According to statistics, the collapse on the bank of Anhui river is increased to by 59 at 76, and collapse on the bank area total length 418km, wherein at middle bar collapse on the bank 16, collapse on the bank is long
83km is spent, 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 storage of Three Gorges, downstream river course is in stream
Measure flood peak smoothization, increased periods.After the upstream of Three Gorges in 2010 experience is let out compared with great flood control, flattening, flood is presented in Anhui river section flood peak
Water increased periods, water level of yangtze river continue about 40 days near flood control warning line, increase tributary flood pressure.
Since Anhui river Riparian Zone sand grain is thinner, side slope extremely unstability in two sides builds bridge pier erosion and deposition on it
Characteristic is extremely complex, and as upland water carrys out husky and periphery side slope variation, 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 carry out early warning to the erosion and deposition of bridge pier.
Under normal conditions, 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, is measured to the depth of water, bed level of the river is scaled by the relationship of the depth of water and elevation, dangerous
Greatly, efficiency is low, and measurement cost is very high.

4, upstream side steel cable is taken using rope hose tool hook, and it is small using lock the vertical steel cable in downstream to be fixed on floating in downstream side
On ship；
5, floating canoe can be rested on to any position of bridge pier side by the dragging of two steel cables；
Using adjacent bridge pier as boundary when 6, being measured if adjacent bridge pier distance is less than 200m, if adjacent bridge pier distance is more than
200m is then using 200m as boundary；
7, along bridge direction, from adjacent bridge pier to tested bridge pier traverse measurement, a section is divided into per 5m；
8, along river direction, gradually discharge steel cable from upstream toward downstream, supersonic sounding instrument with 1 frequency per second into
Row depth survey, steel cable rate of release are 0.5m per second；
9, terminate half of measurement when canoe, which reaches, is tested one half width of bridge pier, floating canoe is taken off with the vertical steel cable in downstream
It opens；
10, canoe is sling using upstream side steel cable, is moved to the other side, continue to measure；
11, after being all measured, data retrieval is subjected to figure structure；
12, multiple measurement results are compared, and calculate scour and fill.
Above-mentioned measurement holder includes horizontal stand and vertical support frame, and horizontal stand stretches out bridge floor and is not less than 4m, vertical to prop up
Frame height 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 strut；
Bilateral is also secured on ring set in 3 above-mentioned lateral struts for fixing steel cable pulls steel wire rope, it is 3 strands unilateral
It pulls steel wire rope to merge and is fixed on the pulley in the lateral strut of turning as one steel wire penetrating；
It is fixed on measuring holder to pull wireline winch；
GPS and supersonic sounding instrument are fixed on above-mentioned floating canoe.
The beneficial effects of the present invention are：
1, the present invention manually need not be operated aboard ship and be obtained with measurement data；
2, method of the invention improves measurement safety, reduces cost；
Section spacing and vertical line can be measured the very little of control, improve measurement accuracy by 3, method of the invention.
