项目摘要

Civil engineers inject cement grouts into the ground for a wide range of applications including ground strengthening and the creation of underground barriers to contain pollutants in rocks and soils. At present, it is not possible to detect where grouts go in the ground. This can result in too much grout being injected (to be on the safe side), drilling of unnecessary injection holes and a lack of data for design. In some circumstances, gaps in grouted underground barriers may remain unknown. This is of particular concern where hydraulic containment is key to safety. This project aims to develop the world's first detectable grouting technology (DETECTAGROUT). We will introduce specialist additives to cementitious grouts. These additives will then enable the grout to be detected using geophysical methods. We will develop a numerical model to accurately predict the 3D shape of the grouted rock volume as it evolves, using methods similar to those used to interpret medical scans in hospitals e.g. MRI, CT and ultrasound imaging. Cement production contributes ~5% of annual global CO2 emissions. DETECTAGROUT could help to lower cement usage and therefore reduce CO2 emissions. reducingatmospheric carbon emissions. Additionally This new detectable grouting system will enable a reduction in cement usage, resulting in a positive reduction of carbon emissions .

土木工程师将水泥灌浆注入地面，用于广泛的应用，包括地基加固和建立地下屏障，以控制岩石和土壤中的污染物。目前，不可能检测灌浆在地下的位置。这可能导致注入过多的灌浆（为了安全起见），钻不必要的注入孔，以及缺乏设计数据。在某些情况下，灌浆地下屏障的间隙可能仍然未知。在液压安全壳是安全关键的情况下，这一点尤其令人关注。该项目旨在开发世界上第一个可检测灌浆技术（DETECTAGROUT）。我们将在水泥灌浆中引入专业添加剂。然后，这些添加剂将使灌浆能够使用地球物理方法进行检测。我们将开发一个数值模型，以准确预测灌浆岩石体积的3D形状，因为它的演变，使用类似的方法来解释医院的医疗扫描，如MRI，CT和超声成像。水泥生产贡献了全球年度二氧化碳排放量的约5%。DETECTAGROUT可以帮助降低水泥使用量，从而减少二氧化碳排放。减少大气碳排放。此外，这种新的可检测灌浆系统将减少水泥的使用，从而积极减少碳排放。
