Method for detecting curtain grouting quality by using GIN grouting method
The invention relates to the technical field of concrete construction quality detection, and discloses a method for detecting curtain grouting quality by using a GIN grouting method. The method comprises steps of judging whether unqualified grouting possibly exists or not by analyzing the GIN grouting curve of each depth section of the last-sequence hole, and then analyzing the GIN grouting curveof the previous-sequence hole adjacent to the last-sequence hole; if the requirement is not met, arranging an inspection hole between the last sequence hole and the previous sequence hole, and selecting the upper limit value of the deeper depth section in the last sequence hole and the previous sequence hole as the depth of the inspection hole; completing grouting in a segmented mode from bottom to top, and monitoring grouting data of all depth segments in real time; analyzing the GIN value and the P value of each depth section of the inspection hole, and if the requirements are met, the quality near the last sequence hole meets the requirements. According to the method, a traditional water pressing method is changed into a GIN mud jacking detection method, the grouting effect and qualityare analyzed and inspected through the grouting curve representation form of the inspection hole, the technical interval is shortened, and the construction period is shortened.
本发明涉及混凝土施工质量检测技术领域,公开了一种利用GIN压浆法检测帷幕灌浆质量的方法。通过分析末序孔各深度段的GIN灌浆曲线,判断是否可能存在灌浆不合格的情况,然后分析与该末序孔相邻的前序孔的GIN灌浆曲线;若也有不满足要求的情况,则在该末序孔和其前序孔之间布置检查孔,并选择末序孔和其前序孔中较深的深度段的上限值为检查孔的深度;从下到上,分段完成压浆,并实时监控各深度段的灌浆数据;分析检查孔每各深度段的GIN值和P值,若满足要求,则该末序孔附近质量满足要求。本发明由传统的压水法检测改变为GIN压浆检测法,通过检查孔的灌浆曲线表现形式来分析检查灌浆效果和质量,缩短了技术间隔,节约了工期。
