Testing device and testing method for testing groutability of calcareous sand grouting
The invention discloses a testing device and a testing method for testing groutability of calcareous sand grouting, and belongs to the technical field of calcareous sand foundation reinforcement. The test device comprises a test system, a grouting system and a data collection system. The grouting system prepares grouting slurry and injects the slurry into the test system; the data collection system collects data such as pore water pressure, soil pressure and slurry flow velocity of the test system; when the grouting system carries out grouting on the calcareous sand in the test system, the data collection system records the grouting process, the grouting pressure, the slurry flow and data such as the pore water pressure, the soil pressure and the flow of the calcareous sand layer of the test system through a camera. The groutability analysis of the grout in the test soil sample stratum is judged through indexes, and the feasibility of grouting reinforcement of the calcareous sand foundation is effectively demonstrated.
本发明公开了一种检验钙质砂注浆可注性试验装置及测试方法，属于钙质砂地基加固技术领域。该试验装置包括测试试验系统、注浆系统和数据收集系统。注浆系统制备注浆浆液并向测试试验系统内注入浆液；数据收集系统收集测试试验系统的孔隙水压力、土压力与浆液流速等数据；在注浆系统对测试试验系统内的钙质砂进行注浆时，数据收集系统通过摄像机记录注浆过程、注浆压力、浆液流量，以及测试试验系统钙质砂砂层孔隙水压力、土压力与流量等数据。通过指标判断浆液在测试土样地层的可注性分析，有效论证钙质砂地基注浆加固的可行性。
