"Small diameter mud water engineering type" small vertical anti-start compatible type! It is a thrusting system compatible with segmented starting, stone slabs, and cobbles.
The "Uncle Mall Super Jr" is a segmented launch and pushing system that allows for recovery from existing manholes by dividing the tunneling machine, making it compatible with stone slabs and cobblestones. Thanks to the segmented launch function of the tunneling machine and the use of half pipes, it is possible to push from small vertical shafts. It comes standard with a reflective directional guidance device (RSG). This ensures that the front end of the tunneling machine is always maintained on the planned line, achieving high construction accuracy. 【Features】 - The segmented launch function of the tunneling machine and the use of half pipes enable pushing from small vertical shafts. - It accommodates a wide range of soil types, including ordinary soil, gravel layers, cobblestone layers, and soft rock. - Maximum gravel diameter is approximately 100% of the nominal diameter. - Gravel ratio is about 80%. - The uniaxial compressive strength of the gravel is approximately 200 MN/m². - The uniaxial compressive strength of the bedrock is approximately 20 MN/m². *For more details, please refer to the PDF document or feel free to contact us.
