Research On The Acidic Soluble Glass Material And The Grouting Technology Design

Injection Grout, which belongs to Foundation treatment, is a foliation of geotechnical engineering science .Injection Grout appears at the beginning of the 19th century. There is about more than 100 years since it was used to deal with the problems in civil works. And also the injection material develops quickly along with the wildly use of the Injection Grout on engineering. At the present it mainly embodies the cement material, the clay material , the soluble glass material and so on. Now, we requires the material which has good capability than before.It is our universal task to find the new grouting material which must have such characteristic: cheaper, no pollution, better infiltration, the high concretion strength, gelatin time in control and construct easily. Numerous graduate schools have made some achievements on the new grouting materials, but it is little which targets the acidic soluble glass. We should do some research about it in a deep lever. The main content and conclusions are as follow:The author have done some experiments to research the gelatin time about the serum and clarify the gelatin time in different conditions. Author have made some futherly analysis about the factors which affect the gelatin time and the reasons why the adjustment of the gelatin time is limited.The author have done some experiments about the consolidation strength of the serum. According to the date of experiments, the author can seize the consolidation strength in different mix and age, and present the relation between it and time at one time.The author have made some other experiments to research the capability of the serum. Basing on the integrated characteristic of the serum and the experience on engineering, the author make some appropriate conjecture about the applied area: the reinforce of the sand stratum, accounting for the speedway harm and serum-jetting process in project.According the capability of the serum, the author make detailed the grouting technology design ,for the reinforce of sand stratum. The design includes the source of the calcium carbonate, the details that we should pay attention to when we make the serum in building site, how to use the CO₂ which is produced when the serum is made and the technic for inspecting the injection effect.
