摘要

捷克共和国开发了测量热泵钻孔灌浆质量的方法和仪器，包括测量部分灌浆钻孔交换管道外的地下水流经钻孔的情况。此外，还开发了一种用于修复岩层的 Semtex 装药，它可以可靠地断开井眼交换管道，而不会对周围的岩石环境或建筑物造成严重损害。由此产生的孔洞可用于重新灌浆，从而防止孔洞中出现不可取的垂直水流。

Methods of grout quality measurement in borehole exchangers for heat pumps and their rehabilitation

Methods and instrumentation for measuring grout quality in heat pump boreholes, including the measurement of groundwater flow through boreholes outside partly grouted borehole exchanger pipes, have been developed in the Czech Republic. A Semtex charge has also been developed to repair rock massifs, which reliably disconnects borehole exchanger pipes without severely harming the surrounding rock environment or buildings. The resulting hole can then be used for regrouting, thus preventing undesirable vertical water flow through the borehole.

期刊介绍： Geothermal Energy is a peer-reviewed fully open access journal published under the SpringerOpen brand. It focuses on fundamental and applied research needed to deploy technologies for developing and integrating geothermal energy as one key element in the future energy portfolio. Contributions include geological, geophysical, and geochemical studies; exploration of geothermal fields; reservoir characterization and modeling; development of productivity-enhancing methods; and approaches to achieve robust and economic plant operation. Geothermal Energy serves to examine the interaction of individual system components while taking the whole process into account, from the development of the reservoir to the economic provision of geothermal energy.
