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.

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.

The "Uncle Mall Shuttle Method" is a construction technique that allows for the retrieval of the tunneling machine when encountering obstacles during excavation, followed by the removal of the obstacles and the re-insertion of the tunneling machine. Since the tunneling machine can be retrieved, there is no need for a reach shaft, and underground connections are possible. It is compatible with a wide range of soil types, including cohesive soil, sandy soil, gravel, gravel mixed with cobbles, and soft rock. 【Features】 ■ Retrieval and re-insertion of the tunneling machine is possible ■ No need for a reach shaft; underground connections are possible ■ Capable of handling obstacles ■ Compatible with a wide range of soil types, including cohesive soil, sandy soil, gravel, gravel mixed with cobbles, and soft rock ■ Equipped with a diameter expansion and contraction function for the tunneling machine cutter head *For more details, please refer to the PDF document or feel free to contact us.

"Expanded" is a header (crusher) that crushes aging existing pipes. Depending on the applicable pipe diameter, it is a compact crusher that can start and reach from a shaft (φ1500mm). Unlike lining methods, there is no loss of effective diameter for the installation of new pipes, resulting in no loss of flow cross-section. 【Features】 ■ Applicable diameters range from nominal sizes 200 to 600mm ■ The replaceable new pipes are push pipes - Ceramic pipes, fume pipes, steel pipes, polyethylene pipes, ductile pipes, etc. ■ Depending on conditions, it is also possible to increase the diameter by one size ■ Safe construction without excavation, allowing for fast renewal (replacement) speed and shortened construction periods *For more details, please refer to the PDF materials or feel free to contact us.

This is a method for constructing a vertical shaft using a circular casing tube without the use of sheet pile supports or liner plates, utilizing a Revo shaft sinking machine. In the Revo method, reaction forces are taken from the main body and counterweight, and a split-type casing tube is driven in by hydraulic jacks, followed by excavation using a clamshell or similar equipment. 【Features】 - The equipment is compact, requiring a small footprint. Additionally, with a main body weight of 3.4 tons, it can be transported by a 4-ton truck. - Even in urban construction, it is less affected by nearby structures and obstacles compared to conventional methods, allowing for efficient work with the use of cover plates. - By advancing the driving process, it avoids pre-excavation and minimizes occurrences of boiling and other issues. The casing driving and extraction are performed using hydraulic jacks, enabling vibration-free and low-noise operations. - The small size of the vertical shaft allows for speedy construction and lower costs. *For more details, please contact us or download the catalog.*
