Permanent Grout Injection Method "Super Multi-Point Injection Method (Simultaneous Multi-Point Injection Method)"
[Coastal Technology Research Center Certification: No. 14002] Demonstrated 19 years of aging consolidation through large-scale field injection tests!
The "Permanent Grout Injection Method" is one of the chemical injection methods. The purpose of improving this method is for permanent improvement, but in recent years, its application range has also expanded as an injection method for temporary improvement. The injection material used is "Permanent Grout," which has been theoretically and empirically validated for permanence, and the injection form is designed to be a permeation injection method that does not disturb the sedimentary state (framework structure) of the ground, with the principle of uniformly improving the ground. The "Super Multi-Point Injection Method" achieves ideal permeation injection and high workability by injecting at an extremely low discharge rate of 3 liters per nozzle, simultaneously from 32 nozzles per pump. 【Demonstration of 19-Year Long-Term Durability through Large-Scale Field Injection Tests】 The results of large-scale field injection tests combining Permanent Grout (injection material) and injection methods (such as the Super Multi-Point Injection Method) have been evaluated for their permeation solidification and long-term solidification properties, earning the 2002 Technical Development Award from the Japanese Geotechnical Society (Yonekura, Shimada). Confirmation tests have continued even after the large-scale field injection tests, and in 2018, the long-term solidification properties were confirmed 19 years later.
