The invention discloses a method for detecting scouring of a foundation of a bearing platform in water, a detection construction structure and a construction method thereof. The invention is used for monitoring and measuring the actual scouring condition of the foundation after the bridge is built.
Description
Technical Field
The invention relates to a method and a structure for detecting scour of a bridge building foundation, in particular to a method for detecting scour of a water bearing platform foundation, a detection construction structure and a construction method thereof.
Background
The flushing of the bridge foundation is a main cause of the water damage of the bridge. Bridge collapse due to flood scour occurs annually throughout the world. The river of China is numerous, developed cities are located on both sides of the river and in the gulf area, and cross-river and cross-sea bridges are increasingly increased to adapt to economic development. In recent years, flood disasters frequently occur in China, and a plurality of bridges are destroyed under the action of flood and tide flushing. And the river bed of the bridge foundation is scoured due to flood and tide, so that the soil around the foundation is elutriated to expose the pile foundation, the free length of the pile foundation is prolonged, and the rigidity and bearing capacity of the foundation are reduced. Therefore, monitoring and measuring the scour condition of the bridge foundation in operation is one of important foundation works for ensuring the safety of the bridge structure.
The detection means for the scouring condition of the foundation of the large-scale bearing platform of the bridge are very troublesome and have higher cost. Although monitoring and detection of bridge foundation flushing have been paid importance, various detection means such as a plunger, a hammer, an acoustic wave and a resistivity method are available at present, for detecting the flushing condition of a large-scale bridge bearing platform foundation, as most of the bearing platform bottom surface is not exposed to the water surface or the exposure is small, ships, measurement facilities and the like cannot enter the bearing platform bottom, and professional divers are required to submerge the bearing platform bottom for measurement by using related underwater sounding instruments. Therefore, the conventional bridge foundation scouring detection becomes very troublesome, and higher detection cost is required every year.
The detection risk of the scour of the large-scale bearing platform foundation of the bridge in the case of flood and large tide is large and even can not be measured. The foundation flushing depth under the conditions of design flood and climax in 300 years is the basic data which is the most concerned and should be monitored by bridge design and bridge maintenance workers. However, for large bridges, the plane size of the large bearing platform is very large, sometimes even exceeds a football field, the piles are more, the pile distance is small, water is very deep in most cases, the bottom surface of the bearing platform is generally not exposed out of the water surface, when flood and climax come, the water flow speed is very high, at this time, a diver enters the bottom of the bearing platform to conduct survey, and the safety risk is very high, and conventional measuring means such as a lifting hammer or an ultrasonic detector cannot measure the depth and the shape of the opposite-flushing pit from the side. In addition, under the state of coastal tidal current reciprocating flow, the situation that the space between the edge of the bearing platform and the river bed surface is too narrow often occurs when the bridge foundation is scoured and detected.
Therefore, the detection method and the detection equipment for the scour condition of the underwater bearing platform foundation, which are simple and convenient to operate and high in feasibility, are developed, and have important significance for monitoring and measuring the scour condition of the bridge foundation and ensuring the safety of the bridge in operation.
