Description

technical field [0001] The invention relates to the technical field of quality detection of the compressive strength of cement soil, in particular to a quality detection device and test method of the compressive strength of cement soil. Background technique [0002] At present, the construction quality inspection method of cement-soil vertically reinforced composite foundation is mainly to drill cores and take samples for compressive strength tests. During the drilling and coring process of the cement-soil vertically reinforced composite foundation, the parts with poor quality are often cracked, damaged, and deformed. Only the parts with good quality can obtain complete core samples suitable for compressive strength tests. It can be seen that the core samples obtained by the traditional core drilling method and subjected to compressive strength are often of better quality, but the poorer quality affects the quality of the project. Therefore, the compressive strength test re...

Problems solved by technology

It can be seen that the core sample specimen obtained by the traditional core drilling method and tested for compressive strength is often a part of better quality, but it is the part of poor quality that affects the quality of the project

Therefore, the compressive strength test results obtained by the core drilling method are incomplete and underrepresented. They are generally unsafe and unfavorable to engineering safety. It is of practical significance to develop a more comprehensive testing method.
