Description
Technical Field
The invention relates to a bridge building foundation scouring detection method and a structure, in particular to an underwater bearing platform foundation scouring detection method, a detection construction structure and a construction method thereof.
Background
Bridge foundation scour is the main cause of bridge water damage. Every year around the world bridges collapse due to flood erosion. China has numerous rivers, developed cities are mostly located on both sides of rivers and in gulf areas, and river-crossing and sea-crossing bridges are increasing to adapt to economic development. In recent years, flood disasters frequently occur in China, and a plurality of bridges are damaged under the action of flood and tidal current scouring. The scouring of the bridge foundation riverbed caused by flood and tide leads to the soil around the foundation to be washed away so as to expose the pile foundation, the free length of the pile foundation is lengthened, and the rigidity and the bearing capacity of the foundation are reduced. Therefore, monitoring and measuring the bridge foundation scouring condition in operation is one of important basic works for ensuring the safety of the bridge structure.
At present, the detection means for the foundation scouring condition of the large-scale bearing platform of the bridge is very troublesome and has higher cost. Although monitoring and detection of bridge foundation erosion are emphasized, various detection means such as inserted bars, hanging hammers, sound waves and resistivity methods are available at present, but for detection of the foundation erosion condition of a large bridge bearing platform, due to the fact that the bottom surface of most of the bearing platform is not exposed out of the water surface or is exposed a little, ships, measuring facilities and the like cannot enter the bottom of the bearing platform, and a professional diver needs to dive into the bottom of the bearing platform to measure by using a related underwater depth measuring instrument. Therefore, the conventional bridge foundation scour detection becomes very troublesome, and higher detection cost is required every year.
The detection risk of the foundation erosion of the large-scale bearing platform of the bridge in flood and heavy tide is large or even the foundation erosion cannot be measured. The foundation scouring depth under design flood and heavy tide conditions in 300 years is the basic data which is most concerned and should be monitored by bridge design and bridge maintenance workers. However, for a large bridge, the plane size of a large bearing platform is very large, sometimes, the plane size of the large bearing platform exceeds one football field, the number of piles is large, the pile distance is small, water is very deep under most conditions, the bottom surface of the bearing platform is not generally exposed out of the water surface, when flood and heavy tide come, the water flow speed is very high, at the moment, a diver enters the bottom of the bearing platform to survey, the safety risk is very high, and the depth and the form of a pit cannot be measured from the side surface by conventional measuring means such as a hanging hammer or an ultrasonic detector. And under the condition that tidal current flows in the coastal reciprocating flow state, when the bridge foundation is scoured and detected, the space between the edge of the bearing platform and the river bed surface is often too narrow.
Therefore, the method and the device for detecting the foundation scouring condition of the underwater bearing platform, which are simple and convenient to operate and high in feasibility, are developed, and have important significance for monitoring and measuring the foundation scouring of the bridge and ensuring the safety of the bridge in operation.
