[0003] The Chinese invention patent application with the authorized announcement number CN105911260B discloses a test device for microbial repair of concrete cracks, including a test tank, in which two concrete specimens opposite to each other are placed. There are gaps formed between the parts; by rotating the transmission screw, concrete cracks of different widths can be quickly formed. Since the width of the cracks is usually various, the existing technology can only form regular cracks with a certain width, and cannot be very fast. The formation of good response cracks has certain limitations for the test

The invention discloses a microbial repair test device capable of changing the crack angle, belonging to the technical field of concrete crack repair. A concrete sample, a rotating support frame, a locking device, an elastic connection device, a sliding support block, a pushing device and a follow-up sealing device, the concrete sample is fixed on the rotating support frame, and the rotating support frame can be along the The longitudinal direction of the test box moves, and a crack is formed between the concrete samples of the two groups of concrete test assemblies. The follow-up sealing device is arranged at the bottom of the crack for sealing. The device of the invention can be used to adjust the width of concrete cracks, so that the test device can adapt to various working conditions, and plays a better guiding role for the subsequent repair of concrete cracks.
Description
technical field [0001] The invention belongs to the technical field of concrete crack repair, and in particular relates to a microbial repair test device capable of changing the crack angle. Background technique [0002] In hydraulic engineering facilities, concrete will crack due to plastic shrinkage, temperature difference, uneven settlement, and excessive bearing capacity. Surface cracks in concrete will accelerate the erosion of concrete, while deep cracks in concrete will cause structural leakage. , affect the stability and safety of the structure. Therefore, it is particularly important to repair cracks in concrete in time. At present, there are many methods for repairing concrete cracks, such as surface spraying, crack filling, crack grouting, etc. At present, with the interdisciplinary and comprehensive development of biology, chemistry, geotechnical and other disciplines, a non-toxic, environmentally friendly and durable microorganism Induced calcium carbonate dep...
