TECHNOLOGY
A method that can increase the transfer strength of the original ground and achieve the nailing effect of reinforcement
by inserting a steel pipe with a packer installed after drilling the excavated slope at regular intervals
and continuously injecting grout using a mobile packer.
Conditions
- •
Where reinforcement and permanent slope stability of cut slopes is required
- •
If the ground is already relaxed or has low self-strength
- •
Developed bedrock fracture zones or fractures
- •
Saturated slopes due to high groundwater levels
- •
Ground with little adhesion or severe weathering
- •
Ground with strong alternation of soft and hard ages due to differential weathering
Effects
- •
Increase the shear strength of the ground
- - Increasing shear strength by pressure grouting
- •
Construction cost savings
- - Reduce construction costs by simplifying sealing and caulking operations
- •
Maximize Grouting Quality Effects
- - Optional application of injection method (1.0Shot or 1.5Shot method)
- •
Air shortening effect
- - Wider installation spacing (C.T.C adjustment) enables air shortening by reducing construction quantity per unit area
- - Simplify processes to make your work more efficient
- •
Highly adaptable
- - Preventing injection material from leaving the site when using rapid payment
- - Easily respond to site conditions by changing construction patterns as ground conditions change
Features of the method
- •
Apply an injectable coking system (pay-as-you-go)
- - Cost depreciation
- - Make your work more efficient, convenient, and reliable
- - Perfect caulking effect (especially effective for groundwater runoff)
- •
Installing an external packer
- - Anti-reflux effectiveness of infusions
- - Simplify sealing operations
- - Grouting and sealing operations at the same time
- •
Apply the Selective Grouting Method
- - Depending on ground conditions, either the 1.0-shot or 1.5-shot method can be applied
