摘要
为实现水下混凝土浇筑标高的自动连续测量,基于测锤探头进入泥浆、浮浆及混凝土3种不同介质中的阻力差异,集成电机驱动系统、计米器、压力传感、PLC及测锤探头运动算法,研发水下混凝土浇筑标高自动监测装置。测锤探头实时反馈阻力值,并根据设定的压力控制阈值自动控制测锤探头动作;计米器实时显示当前标高监测结果。自动监测装置经过两代产品迭代,分别在武汉双柳大桥项目及广州狮子洋通道工程中应用。标高监测结果与浇筑量换算标高及人工测量结果的对比表明,第一代产品由于动作简单,自动测量模式下易被埋入混凝土,导致结果不准确;而第二代产品提高了智能化程度,测量结果与人工测量结果和浇筑量换算结果接近,且较人工测量结果更稳定。
In order to realize automatic and continuous measurement of underwater concrete pouring elevation,an automatic monitoring device for underwater concrete pouring elevation is developed based on the difference of resistance of the hammer probe into three different media,namely mud,floating slurry and concrete,which integrating motor drive system,meter counter,pressure sensor,PLC and the motion algorithm of the hammer probe.The measuring hammer probe feeds back the resistance value in real time,and automatically controls the action of the measuring hammer probe according to the set pressure control threshold.The meter counter displays the current elevation monitoring result in real time.After two generations of product iteration,the automatic monitoring device is applied in Wuhan Shuangliu Bridge project and Guangzhou Shiziyang Passage project respectively.The elevation monitoring results are compared with the conversion elevation of pouring volume and manual measurement results.The result of the first generation product is inaccurate due to its simple action and easy to be buried in concrete under the automatic measurement mode.The second generation of products has improved the degree of intelligence,and the measurement results are close to the manual measurement results and the conversion results of poured volume,which is more stable than the manual measurement results.
