泥浆质量鉴定在地下连续墙等施工方法的泥浆作业中,对工程的施工、经济性特别是建筑物的性能来说,是必不可少的.在泥浆质量中,形成泥皮的能力,也就是说造壁性能对稳定孔壁是很重要的管理项目.然而,现行的泥浆造壁性能试验是加压或减压的滤失性试验.所用仪器繁杂,操作也麻烦.为此,研究了造壁性能试验的自动化,提出了一种与以往方法不同的全新的试验方法,即是计测(意即测试、检测,下同)泥浆中自由水浸入吸水性滤纸的一定距离时毛细管上升时间的方法.并使该方法自动化.从而开发出泥浆造壁性能自动试验装置.通过现场应用结果表明,该装置计测值的再现性(即真实性,下同)好,能在短时间内自动地评定泥浆造壁性能.
Mud Quality Identification In slurry operations such as the construction of underground continuous walls, it is essential for the construction and economy of the project, and in particular the performance of the building. In mud quality, the ability to form a mud crust To say that wall building performance is a very important management project for stable pore walls, however, the current mud wall building performance test is a pressure or reduced pressure fluid loss test with complicated equipment and troublesome operations.Therefore, A new test method different from the previous method is proposed to automate the testing of the wall performance. It is to measure the rise time of the capillary at a certain distance when the free water in the mud is immersed in the water-absorbing filter in the test (ie testing, testing, the same below) Method, and the method is automated to develop an automatic test device for the wall property of the slurry. The field application results show that the measured value of the device reproducibility (ie, authenticity, the same below) is good, and can automatically Assessment of mud wall properties.
