- Trench Cutting Re-mixing Deep Wall Machine
Trench Cutting Re-mixing Deep Wall Machine
The Trench Cutting Re-mixing Deep Wall Machine (also known as TRD construction method machine) is mainly used for constructing underground continuous walls, and its core application scenarios are various projects that require anti-seepage, waterproofing, and soil retention. It can be specifically divided into the following categories
- Reservoir dam anti-seepage reinforcement;
- River and Lake Seawall Defense Engineering
- Building foundation retaining wall; During the construction of high-rise buildings or underground structures, as a supporting structure for foundation pits, it resists lateral pressure from the soil and prevents collapse
- Subway and tunnel engineering: used for the construction of subway stations, shield shafts, and underground passages, playing a role in waterproofing and retaining soil, ensuring the waterproof safety of underground engineering construction
- Harbor engineering: used to construct water stop walls to resist lateral infiltration of seawater when building breakwaters or docks in coastal areas

Method Process Principle
- Principle: After the chain-blade cutting tool is cut vertically and continuously to the design depth, it is pushed horizontally and injected with cement slurry to form a continuous, equal thickness and seamless cement wall .
- Insert core material (H-shaped steel, etc.) into the cement mixing wall of equal thickness to form a composite retaining and water stop structure.
TRD Method Features and Scope
- lt 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 400-950 mm
- The cement is evenly mixed, and the unconfined compressive strength is 0.5-2.5MPa,
- The wall has good water resistance, and the permeability coefficient can reach 1×10-6 cm/s to 1×10-7 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.

Single shaft mixing machine
This rig is specifically fitted with a mixing device for the DSM method (such as double-axis or triple-axis mixing drill rods). During construction, the rig provides stable vertical lift and downward pressure, driving the drill rods to rotate and inject cement grout, forcibly mixing soft soil with the solidifying agent to form underground continuous walls or reinforced blocks.
Application Scenarios: Soft Ground Reinforcement
Cutoff Wall: Forms an interlocking continuous wall for water isolation in excavation pits.
Foundation Reinforcement: Enhances the bearing capacity of soft ground and reduces settlement.
Environmental Remediation: Used for in-situ solidification treatment of contaminated soil.
CFA Long Auger Drilling Rig
The ZB series CFA long auger drilling rig is operated by an electrical hydraulic system and adopts a walking mode or crawler base. When working, the long auger drilling rig is used to drill to the design elevation, and when lifting the drill, concrete is pumped into the pile through a concrete conveying pump (or a steel cage can be inserted later). Both drilling and piling are completed synchronously with one machine. The installation of rotary heads can also be used for various foundation construction techniques such as superfluid and long spiral drilling piles.
Fully Hydraulic CFA Drilling Rig
The fully hydraulic CFA (continuous spiral drilling pile) drilling rig is the core equipment for modern pile foundation construction, with high efficiency, low noise, environmental protection, and stable pile quality as its core advantages. It is widely used in urban and complex geological foundation engineering.
