High Quality Trencher Machine
Brief Introduction: FMT-600 trencher provides a real systematic integrated solutions for laying of underground cable.“City trencher " doesn’t belong the category of “Trenchless technology”. But due to its special technical characteristics, can be considered a “no mining” .The max. width of grooving is 50mm,The max. depth of grooving is 300-600mm. Speed of grooving: 1-1.3m per minute Technical Specification of Road Trencher:

Trenching technologies: “Micro-trenching” is an innovation of science, owning following advantages: --Lowest operation cost --Highest working efficiency --Within 50mm width, the slotting jobs doesn’t impact the pavement structure. --Lowest impact on the natural environment. For example: Control the mining earthwork quantity, backfill earthwork quantity and low pollutant emission(Very low energy consumption) --Lowest impact on the social environment For example: Lowest impact on the urban road traffic, effectively reduce the noise emissions City grooving jobs steps: 1) Set the working area and use the GPR survey(In case of need) 2)Grooving 3) Laying microduct or cluster 4) Backfilling 5) Recovery pavement with asphalt 6) Use blowing machine to place fiber unit or micro line FCST’s Recommendation Scheme: A. The best cable groove size : Width: 40~120 mm Depth:300~600 mm B. The construction site should have warning labels C. Clean up the road surface and groove. D. Should be having the possibility to pave new asphalt within 24 hours. E. Use reasonable cold asphalt to instantly fill the grooves. F. Cable laying path should use different color concrete method or use other tags to mark.
