介绍了HQC40混凝土强度检测仪,该仪器主要用于喷射混凝土的强度检测,其检测原理为点荷载法,具有高效、快速、经济、可靠、省时和省工且易操作等特点,为煤矿井下及其它锚喷支护工程质量的检测提供了一种实用的工具。结合其实际应用给出了若进一步提高混凝土强度检测仪的精度,对检测仪的要求和改进措施。 The paper introduces the HQC40 concrete strength tester, which is mainly used for the strength testing of shotcrete. The testing principle is point load method, which has the characteristics of high efficiency, quickness, economy, reliability, time saving, labor saving and easy operation. And other Anchorage support engineering quality inspection provides a practical tool. Combined with its practical application, if the accuracy of the concrete strength tester is further raised, the requirements of the tester and the improvement measures are given.
