为了增强錐探灌漿的能力和扩大錐探灌漿的使用范圍,我局今春組織試驗小組进一步作了压注灌漿試驗。这次試驗的目的在于解决堤身隐患問題、試驗使用漿料問題、基础加固問題和解决灌漿机与拌漿机等問題。試驗地点是在济南处老徐庄。試驗从4月11日起至6月上旬止,在外試驗共兩个月。試驗使用灌漿机2部,拌漿机1部(均系我局今春試制,見下圖)。通过本次試驗,初步确定了压力灌漿的效果和今后如何使用压力灌漿来解决堤身隐患等一些有关的基本問題。茲將試驗結果总結报告如下: 一、使用泥漿的物理性能: 泥漿可由粘土顆粒大小的不同而形成悬浮質或者膠体質的狀态,一般如均匀分布于液体中的粘土顆粒小于0.2M(1,000M=1公厘)并占有相当数量者称为膠体泥漿。如粘土顆粒小于0.2M的数量很少,或
In order to enhance the ability of cone penetration grouting and expand the scope of cone grouting, our bureau organized a further injection grouting test in spring. The purpose of this experiment is to solve the hidden problems in the dike, test the use of slurry, the basic reinforcement problems and solve the grouting machine and mixer and other issues. The test site is located in Jinan, Xu old village. Test from April 11 until the beginning of June until the test outside a total of two months. The experiment uses two filling machines and one mixing machine (all are trial-produced by our bureau in spring, see below). Through this experiment, some basic problems such as the effect of pressure grouting and how to use pressure grouting in the future to solve the hidden problems of the dam body are preliminarily determined. The summary of the results of the test report is as follows: I. Physical Properties of Mud: Mud can be suspended or colloidal depending on the size of the clay particles. Generally, clay particles uniformly dispersed in a liquid are less than 0.2 M (1,000 M = 1 mm) and occupy a considerable number of people known as colloidal mud. If the amount of clay particles is less than 0.2M, or
