化学注浆法,过去从施工简便和经济性出发,大多使用钻杆注浆方式。但由于地基复杂等原因,注浆效果缺乏可靠性,而且往往造成公害问题。因此急需研究出更可靠的施工方法。为了这个目的,创造出新型的双重管注浆法,兼有钻杆注浆方式的简便、经济性以及花管注浆方式的可靠性。通过大规模试验坑注浆试验,与钻杆注浆和花管注浆进行比较,具
Chemical grouting method, the past from the construction of simple and economical, most of the use of pipe grouting method. But due to the complex foundation and other reasons, the lack of reliability grouting effect, and often cause pollution problems. Therefore, an urgent need to study a more reliable construction methods. For this purpose, a new double-tube grouting method has been created, which combines the simplicity of pipe-grouting, the economy and the reliability of the pipe-grouting method. Through large-scale test pit grouting test, compared with the pipe grouting and flower pipe grouting, with
