Drillmaster New Product – Trench Cutting Re-Mixing Deep Wall (TRD) Machine

A Trench Cutting Re-Mixing Deep Wall (TRD) machine is a specialized piece of equipment used in civil engineering and construction projects, particularly in large-scale infrastructure developments like deep foundation construction, underground structures, and diaphragm wall construction.

The working process of a Trench Cutting Re-Mixing Deep Wall (TRD) machine involves several steps, which typically include trench cutting, mixing of excavated soil with additives if necessary, and construction of deep walls.

- Preparation: Before operating the TRD machine, the construction site must be properly prepared. This involves clearing the area where the trench will be cut, ensuring the ground is stable, and setting up safety measures.

- Trench Cutting: The TRD machine is positioned at the desired location for the trench. Using its cutting mechanism, which may involve rotating blades or other cutting tools, the machine excavates the soil to the required depth and width to create the trench. The depth and width of the trench are determined by the specific requirements of the construction project.

- Soil Mixing: Once the trench is cut, the TRD machine may incorporate a mixing function to blend additives or other materials with the excavated soil. This mixing process may involve the injection of additives directly into the trench or the use of mixing arms or blades attached to the machine. The purpose of soil mixing is to improve the properties of the soil, such as strength, stability, or permeability, to meet the requirements of the project.

- Construction of Deep Wall: After the soil is adequately mixed, the TRD machine begins the process of constructing the deep wall within the trench. This typically involves placing reinforcing elements, such as steel bars or cages, into the trench to provide structural support. The machine then fills the trench with concrete or another suitable material, forming the deep wall as it progresses along the trench's length. The construction of the deep wall continues until the desired depth is reached or until the entire length of the trench is completed.

- Finishing and Quality Control: Once the deep wall is constructed, the TRD machine may perform finishing tasks, such as smoothing the surface of the wall or removing any excess material. Quality control measures are also implemented to ensure that the constructed deep wall meets the required specifications and standards for strength, stability, and integrity.

- Maintenance and Cleanup: After completing the trench cutting and deep wall construction process, the TRD machine requires maintenance to ensure its proper functioning and longevity. This may involve cleaning the machine, inspecting and lubricating its components, and making any necessary repairs or adjustments.

Trench Cutting Re-Mixing Deep Wall (TRD) Machines and Double-wheel Trench Cutters are both used in civil engineering and construction projects for excavating trenches, but they differ in their specific capabilities and functionalities. Here's a comparison between the two:

- Purpose and Functionality:

TRD Machine: TRD machines are designed not only to cut trenches but also to mix the excavated soil with additives or other materials if necessary. They are specialized machines capable of constructing deep walls, typically used in projects where stability and load-bearing capacity are critical, such as building foundations or underground structures.

Double-wheel Trench Cutter: Double-wheel trench cutters are primarily focused on excavating trenches. They may not have built-in mechanisms for soil mixing or deep wall construction. Their primary function is to efficiently and precisely cut trenches to the required depth and width.

- Construction Technique:

TRD Machine: TRD machines often employ advanced construction techniques, such as soil mixing and deep wall construction, to enhance the properties of the soil and create stable foundation elements. They may incorporate features like mixing arms, injection systems for additives, and mechanisms for placing reinforcement elements within the trench.

Double-wheel Trench Cutter: Double-wheel trench cutters typically use cutting wheels or blades to excavate trenches. They may be equipped with adjustable cutting depths and widths to accommodate various project requirements. However, they generally focus solely on excavation without additional soil treatment or deep wall construction capabilities.

- Complexity and Cost:

TRD Machine: TRD machines are often more complex and specialized than double-wheel trench cutters due to their additional functionalities for soil mixing and deep wall construction. As a result, they may be more expensive to purchase or rent and require specialized training for operation.

Double-wheel Trench Cutter: Double-wheel trench cutters are typically simpler in design and functionality compared to TRD machines. They may be more cost-effective for projects that primarily require trench excavation without the need for soil treatment or deep wall construction capabilities.

Here are application of Trench Cutting Re-Mixing Deep Wall (TRD) Machine:

- Projects: For anti-penetration in areas with abundant groundwater, used in subways, large shopping malls, dam reinforcement, contaminated soil treatment and other projects.

- Geology: For clay soil, sand, gravel and gravel layers. It also has good applicability in dense sand layers with a penetration value of 30~60 and soft rocks with a saturated uniaxial compressive strength not exceeding 10MPa..
