Outline of the
Construction
Method
Construction method that can fill the injection tube during the process of tunnel excavation, to fill the poured adobe with infusion material, and fill the ground with high-flowing material to effectively apply the method to prevent further collapse and ground deformation. A method of laying steel pipes in proper shape before tunnel excavation and inje -ction materials to form a Beam Arch by integrating the steel tube and surrounding ground with ground-tightening by injection materials to obtain both differential and reinforcement effects. It is a method of solidi -fying the ground using urethane drugs with two -liquid foam components. It is an auxiliary technique for en -tering a small-caliber landscape or rebar into a tunnel membrane to prevent local membrane boron by preventing ground deformation before digging a tunnel.
Injection material cement+ bubble agent+fluidizer+ rapid settlement. cement+silicate soda TBU(A), CBU(B)urethane solution cement
Application purpose - drag and borax prevention water and ground reinforcement fish hole and borax protection borax prevention

- Easy to install injection pipe and check hole
- Geotechnical consolidation at the time of tunneling Excellent on ground rein-forcement effect by integration
- Easy to handle due to its light weight
- Possible to manifest various compre-ssive strength (10 ~ 50kg / ㎠)
- No order effect
- Process is complicated and time consu-ming and costly
- The weight of the steel pipe is big and the workability is lowered.
- Damage of bending part of injection hole when inserting steel pipe seal material and perforated slime into steel pipe Difficult to install packer
- The steel pipe is closely attached to the lower end of the hole, The injection effect of the excavation line part is falling, And oysters frequently occur
- Excellent order effect
- Simple work contents
- The injection solution is expensive
- Environmental pollution problem
- The length of the indentation bolt is Limited within 6m) Various applications are difficult
- Ground reinforcement effect is low
- Simple process
- It is installed every time And manpower consumption
- The longer the drill length Reduced support effect
- To FRP or steel pipe multi-stage grouting Compared to reinforcing effect
- Crack joint and shattered ground Low reinforcement effect
- Severe groundwater leakage is not applicable
