The maintenance device of little bioremediation rock crack that this scheme provided is different from the slip casting method that adopts in most research processes in the past, but the experimental apparatus of a direct soaking, and little bioremediation liquid can be easier gets into and carries out the induced calcium carbonate sediment in the rock crack, and its result is just that the sediment distributes more evenly, and the effect is more outstanding.
Description
Technical Field
The utility model relates to a building engineering technical field specifically is a microbiological remediation rock crack's curing means.
Background
In geotechnical engineering, the phenomena of rock cracking and leakage caused by various geological reasons widely exist, the mechanical property and durability of the rock are greatly reduced, and huge potential safety hazards can be caused if the rock is not repaired in time. The traditional crack repair is generally implemented by grouting with slurry materials such as cement and chemical materials, but the traditional crack repair has the defects of poor compatibility, high cost, high pollution and the like in the using process, so that more researchers begin to implement the research on the crack repair by using microorganism-induced calcium carbonate precipitation (MICP). MICP is an eco-friendly energy-saving technology, has the advantages of low energy consumption, multiple types, environmental friendliness and the like, and is widely applied to crack repair of geotechnical engineering. The microbial repairing liquid has the characteristics of small volume, low viscosity, high permeability and the like, and can quickly enter a narrow crack to fill and seal the crack. Based on the needs of laboratory research, this application proposes to provide a maintenance device of little bioremediation rock crack.
SUMMERY OF THE UTILITY MODEL
