TRD-60D/60E Trench cutting & Re-mixing Deep wall Series method equipment

Short Description:


Trench cutting Re-mixing Deep wall method (TRD for short) is different from Soil Mixed Wall method (SMW). With TRD method, the chain saw tools are mounted on a long rectangular section “cutting post” and inserted into ground, to be moved transversely for cutting and grout pouring, mixing, agitating, and consolidation of soil at the original location, so as to make an underground diaphragm wall. This mechanism has been first developed in Japan in 1994 for making cut-off walls or slurry diaphragm walls, which has been widely used in subway stations, landfills, impermeable walls to prevent contamination from ground water, etc. TRD method has been widely used in job sites in Japan since 1990s. TRD method get rapid development, since TRD was first introduced to China in 2009. Only in the year of 2018, the total wall areas made by TRD method is up to 1 million square meters and over 80 projects in domestic.

    1. High Security of TRD Equipment

    TRD equipment is less than 35% of traditional method machine in height

    .2. Continuous, Constant Thickness and Joint-free Wall

    Transverse movement of cutting post makes continuous join-free wall with high impermeability

    Constant thickness wall is suitable for inserting H-beam with any distances.

    3. Walls of Homogeneity and Equal Strength

    Vertical movement of cutting chain, mixing soil with concrete slurry, all of these assure a high quality of homogeneity wall.

    Compared with traditional method, TRD makes thinner walls with same impermeability.

    4. High Accuracy

    All the main working institutions have measuring sensors, which can effectively monitor the straightness and verticality of the wall to ensure the precision of the wall.


    1.High Power & High Efficiency

    Imported high-power engine and high-power hydraulic drive motor are adopted to provide larger cutting propulsion and lifting force of cutting system, ensuring larger cutting torque and reliable power supply.

    2.Famous-brand Spare Parts & High Quality

    Imported famous-brand hydraulic components, which assure the equipment’s stability and security.

    Imported famous-brand hydro power cutting system with low speed and large torque, which is stable and reliable, produces low heat and ensures long-term continuous work.

    Imported famous brand electric control proportional pump, can control the torque and rotation speed of cutting mechanism according to the program, improve the flexibility of construction and quality control.

    3.Track Base Machine & High Stability

    TRD equipment is designed in compact structure and suitable for various ground conditions. Base machine can be transported integrally.

    Rotary track base machine reduces ground pressure, makes stable and easy travel, good displacement straightness during construction.

    Compared with the crawler base machine, track system is more suitable for deep cut in hard ground.

    Transverse-moving-track with main frame inlay transmits the reacting force to the track,

    to avoid the damage of jack cylinders. Four pairs of jack cylinders, eight in total. Each track can act with solo jack or dual jacks, which assures balancing operation of the equipment.

    4. Smart Control & Facile Operation

    Inclinometers for each main structure, provides easy control and feedback of the equipment.

    Smart control of outrigger cylinder, provides automatic deviation correction when the cutting post works. It assures the quality of wall making and easy operation.

    Smart control of the torque avoids overload and damage of the equipment.

    5. Dual Power Systems & Advanced Technology

    Two power systems for TRD equipment: Main power (Diesel) and Auxiliary Power (Electric), which works independently. But the Auxiliary power can be substitute for the Main power when the fuel supply is cut off or the machine is halted. In this case, the cutting post can be safely parked in the trench without being cemented in.

    6. Localization service& Better guarantee

    Special designed cutting chain for TRD method, with lube-bath technology, high quality materials and favorable price, stock available anytime.

    Sprocket (Driving wheel) is made with alloy materials, fine machining. Sufficient supplies and timely delivery.

    Follower (Driven wheel inserted in underground) is designed with special sealing technology. Imported famous brand bearings and cement-proof seals. Sufficient supplies and good maintenance service.

    Exclusive supplier of the cutter. Imported, sufficient supplies and easy maintenance.
