Description
Technical field
The utility model belongs to transport and communications field, particularly a kind of pier subsidence measuring instrument.
Background technology
Bridge is the important component part of road and rail traffic, and the quality of its maintenance situation directly affects the unimpeded of road and traffic safety, also namely directly affects economic benefit and the social benefit of road and rail traffic, accounts for very important effect in national economy.China's bridge that has vast territory is numerous, shows existing highway bridge more than 50 ten thousand, be built in each different times respectively according to interrelated data, and development is flourishing especially in recent years.
China has numerous bridge to be in the cheuch of remote mountains, China's complex geologic conditions, many highways, railroad bridge are in the cheuch of remote mountains, physical features is dangerous, be easy to rainy season form torrent, moreover most of bridge that China builds in one's early years generally adopts gravity pier, platform and open cut shallow foundation, it is particularly serious to be washed away the situation of impact.The safety of torrent to bridge causes grave danger.Washing away is the erosion scour processes of current to riverbed, and riverbed silt, under flow action, is moved to downstream and causes riverbed to reduce or water front retrogressing.China is the more country of flood, and bridge disaster by flood is caused by bridge scouring mostly, washes away therefore to bridge pier the important topic that detection also just becomes bridge.As there is heavy rain during flood season in August, 2010, Baoji-Chengdu Railway Guanghan Shi Ting Jiang great Qiao, by flood erosion, once caused 2 bridge piers to be destroyed by rush of water, narrowly led to major accident.
Flood season, partial rivers flow velocity was large, and ship cannot navigate by water, and was now difficult to realize to the detection of pier subsidence.At present frogman is also mainly relied on to touch the method for spy and lining rope, supersonic sounding to the detection of bridge scouring disease, but these method costs are high, can not monitor continuously, in flood season, the river frogman that The turbulent river crashes its way through cannot operation, ultrasonic probe is owing to cannot keep vertical with the water surface by water impact, also cannot measure the depth of water, facts have proved in flood season, the existing method in river that The turbulent river crashes its way through inapplicable.
Can not to monitor continuously bridge foundation washout for environmental quality and present stage residing for the bridge pier in operation and in the inapplicable present situation in the river that The turbulent river crashes its way through, reasonably a set of pier subsidence measuring instrument of design is particularly crucial.
