水下清淤取样检测器具的研究与应用

基槽清淤质量目前尚无可直接采用的成熟检测方法，为解决这一难题，经过大量现场调研，结合本项目特点和以往的施工经验，研制了“封闭旋进取泥器”和“潜底定位取浆器”两项专利技术，并针对深圳机场扩建工程提出了可供实际操作的准确定量的基槽清淤检测方法，从而解决了这一工程难题。通过深圳机场扩建工程清淤质量的检测，证实该技术的可靠性，并可在类似的工程中推广应用。

Study and Application of Underwater Dredging Sampling Testing Apparatus

At present no mature methods about checking on the quality of mud-cleaning of foundation trough can be used directly. For solving this problem, through a large number of market surveys, combined the characters of this project with construction experiences, and developed these two kinds of patent apparatuses. They are ＂mud catcher with seal and function of drill＂ and ＂mud collector with function of diving to the bottom and location＂ . To aim at the extension project of Shenzhen airport, a nicely quantitative method of mud-cleaning of foundation trough and quality requirement of mud-cleaning are provided to solve this project problem. Through checking the quality of mud-cleaning in Shenzhen airport extension project, these technologies are proved to he reliable, and they can be introduced to spread and apply to similar projects.
