TRD Method - Features and Scope

  • It is applicable to clay, sand, gravel and gravel layers, and also has good applicability in dense sand layer with 30-60 standard penetration value and soft rock with saturated uniaxial compressive strength not exceeding 10 MPa.
  • The depth of the finished wall can reach 70 meters, and the verticality deviation shall not be greater than 1/250 (when the TRD verticality deviation is not greater than 1/300 when it is used as the reinforcement of the inner and outer trench walls of the ground wall).
  • Wall thickness range: 550 - 950 mm.
  • The cement is evenly mixed, and the unconfined compressive strength is 0.5 - 2.5 MPa.
  • The wall has good water resistance, and the permeability coefficient can reach 1x10-6 cm/s to 1x10-7 cm/s in sandy soil.
  • The spacing of the interpolated profiles can be evenly arranged with equal spacing, and the rigidity of the enclosure is more uniform.
  • The maximum height of construction machinery is generally not more than 12 meters, and the center of gravity of construction frame is low, with good stability.

Frequently Asked Questions

What is the working principle of the TRD method?

The TRD (Trench cutting Re-mixing Deep wall) method uses a chain-blade cutting tool to cut vertically and continuously to the design depth. It is then pushed horizontally while injecting cement slurry to form a continuous, seamless cement wall of equal thickness. Finally, core materials such as H-shaped steel are inserted to create a composite water-stop and retaining wall structure.

Which soil layers are suitable for TRD construction?

This method is highly applicable to clay, sand, gravel, and gravel layers. It also shows excellent performance in dense sand layers with standard penetration values of 30-60, and soft rock with a saturated uniaxial compressive strength of up to 10 MPa.

What is the maximum depth and verticality deviation of TRD walls?

The finished wall depth can reach up to 70 meters. The verticality deviation is controlled to not exceed 1/250. When used specifically for inner and outer trench wall reinforcement of ground walls, the verticality deviation can be controlled to not exceed 1/300.

What wall thicknesses can be achieved using the TRD method?

The TRD method can construct walls with thicknesses ranging from 550 mm to 950 mm, providing excellent flexibility for different structural requirements.

How effective is the water-stop performance of TRD walls?

The TRD wall provides outstanding water resistance. In sandy soil, the permeability coefficient of the wall can reach as low as 1x10-6 cm/s to 1x10-7 cm/s, ensuring exceptional seepage control.

Why is the stability of TRD machinery superior?

The construction machinery has a low overall profile, with a maximum construction height of no more than 12 meters. This low center of gravity provides the machine frame with outstanding stability and safety during operations.
