Description

Technical Field

[0001] The present application relates to the technical field of building test detection devices, and in particular to a device for detecting the penetration degree of soil bacteria liquid in fertilizer trough backfill based on ground penetrating radar. Background Art

[0002] With the advancement of urbanization, urban population density continues to increase, and land resources are tight. In order to solve the problem of urban population concentration and land use, the number of high-rise and super-high-rise buildings continues to increase, and the number of deep foundation pit projects is also increasing. As the density of urban buildings continues to increase, the construction environment of new buildings between existing buildings becomes more and more complex, and the construction space reserved in the foundation pit becomes more and more narrow and sensitive. Therefore, the construction of the fertilizer trough backfill in the foundation pit becomes more and more difficult, and the quality of the fertilizer trough backfill becomes more and more difficult to guarantee.

[0003] In recent years, microbial induced calcium carbonate precipitation (MICP) technology, as a new technology for modifying the water-mechanical properties of rock and soil, has been increasingly used in the fields of foundation treatment, prevention of sand liquefaction, soil reinforcement, restoration of rock and soil cultural relics, and marine geotechnical engineering. In the backfill of building fertilizer troughs, MICP technology has begun to attract attention due to its characteristics of not causing mechanical or chemical damage to the environment and infrastructure. In MICP technology, microorganisms require a certain humidity for growth and metabolism, and the carbonates produced need to form solid minerals with metal ions dissolved in water to reinforce the soil. Therefore, when using MICP technology to reinforce the backfill soil of the fertilizer trough, the method of spraying bacterial solution on the backfill soil doped with calcium sources and nutrients is adopted. However, there are places where the bacterial solution cannot penetrate in place during the construction process, which reduces the overall reinforcement quality of the fertilizer trough backfill soil.
