TRD-D machine

TRD.jpg

TRD method is realized by professional equipment TRD method. Our company's joint construction unit has summarized a large amount of construction experience, combined with domestic geological characteristics and operating conditions, after field investigation and technical research, mastered the full set of TRD technology, and developed and trial-produced an ultra-deep TRD. Construction machine. The construction depth reaches 61 meters and the wall width is 900mm. It is a professional construction equipment that currently meets China's working conditions.

The TRD method can be used for construction of cobblestones with a diameter of less than 100mm and extremely soft rock with uniaxial compressive strength ≤ 5 MPa. Large-scale anti-seepage walls can also be constructed in general sandy soil foundations, with a maximum construction depth of 65 m. At the same time, this method of construction also has a wider range of foundation adaptability than traditional techniques, and also has many achievements in foundations with pebbles or large stones, Ryukyu limestone, etc. Apart from Japan, it is also widely used in the United States and Singapore. This method has been widely used since its introduction into China, and has a very broad development prospect.

Scope of TRD method:

1. Temporary support impervious wall: basement of the building, sewage treatment facilities, tunnel excavation, subway engineering, etc.

2. Permanent anti-seepage wall: anti-seepage for reinforced reservoirs, dams, groundwater dams, industrial waste treatment facilities, etc.

3. Other foundation improvements: foundations of buildings, foundation measures of dams, harbor facilities, oil storage tanks, sinking prevention walls, etc.
