"Small-diameter mud-water engineering type" suitable for small vertical anti-launch! The excavation machine can be divided, allowing recovery from existing manholes.
The "Uncle Mall Mini" is a split launch compatible propulsion system that enables propulsion from small vertical shafts, utilizing the split launch function of the boring machine and the use of half pipes. It is equipped with a standard reflective directional guidance device (RSG). This ensures high construction accuracy by keeping the tip of the boring machine consistently on the planned line. It is compatible with a wide range of soil types, including cohesive soil, sandy soil, gravel, gravel mixed with cobbles, and soft rock. 【Features】 - The boring machine can be split for retrieval from existing manholes. - It accommodates a wide range of soil types, including cohesive soil, sandy soil, gravel, gravel mixed with cobbles, and soft rock. - Maximum gravel diameter is approximately 40% of the nominal diameter. - Gravel ratio is about 60%. - The uniaxial compressive strength of gravel is approximately 200 MN/m². - The uniaxial compressive strength of soft rock is approximately 5 MN/m². *For more details, please refer to the PDF document or feel free to contact us.
