The "PIT Method" is a swinging pressure-injection type shaft construction machine that minimizes manual work underground, with human operations carried out above ground, making safety management easier. Since excavation can proceed while securely retaining the soil with casing, there are no concerns about ground collapse or subsidence of the roadbed. 【Features】 ■ Excellent safety ■ Superior workability ■ No vibration and low noise ■ Good operability ■ High precision finish *For more details, please download the PDF or feel free to contact us.

The "Sanguan King (R) DRM MVP1450" is a thrusting machine that can be launched in locations where there are many buried objects such as gas pipes and water pipes, and can only be constructed in a shaft with an inner diameter of 1450 (liner 1500). If the pressure of the hydraulic unit is 21 MPa or higher, it can be operated with your existing unit. 【Main Specifications】 ■ Minimum launch shaft: φ1450 (1500 liner plate) ■ Pipe type for construction: Rigid PVC pipe (adhesive spiral joint) ■ Thrusting ・ Thrust force: 206KN (21MPa) 294KN (30MPa) ・ Pull force: 140KN (21MPa) 202KN (30MPa) ・ Speed: -cm/min ・ Stroke: 1,080min, etc. * For more details, please download the PDF or feel free to contact us.

The "Sanguan King (R) DRM MVP301" is a small-diameter pipe jacking method that can accommodate saturated sand layers. It allows for control of the amount of soil intake during jacking. Complete water stoppage can be achieved when setting the pipe, preventing auger sticking. 【Features】 ■ Permeability coefficient K = 10(-2cm)/SEC to 10(-3cm)/SEC or less ■ Water head difference within 3 to 5m ■ Control of soil intake during jacking is possible ■ Tools can be used interchangeably with other models ■ Launching pit φ1500 is possible (Note: Pipe length 0.5m) *For more details, please download the PDF or feel free to contact us.

The "Pit Mini Method" uses a Pit Mini machine to install drainage pipes within residential land when setting up a sewer drainage pit. It involves pressing retaining materials into the ground, loosening the soil inside the retained rigid PVC pipe with a high-pressure jet pump, and removing the soil with a powerful suction vehicle to lower it to the specified depth. This method constructs a reach pile for public pits and small manholes, as well as for the "Urinbo Method" PVC pipe pushing. It operates with no vibrations and low noise, taking into consideration the global environment. 【Features】 ■ Can be transported and delivered anywhere (by workers) ■ Simple machine structure, making maintenance easy ■ Suitable for locations that can only be constructed manually, such as fences, hedges, within residential areas, indoors, and areas with elevation differences ■ No risk of collapse of the surrounding ground due to excavation ■ Installation of φ300 small manholes is also possible *For more details, please download the PDF or feel free to contact us.

The "Strike Method" is a pipe installation and pushing method that combines effective ground improvement by injecting chemical solutions after the arrival of the casing pipe at the main pipe to be installed. Even when installing the main pipe under busy roads, construction can be carried out from a distant shaft, contributing to the alleviation of traffic congestion. 【Features】 ■ Installation of a φ150mm pipe onto a φ200mm PVC pipe ■ Installation onto fume pipes and shields ■ Starting from a φ2,000 casing shaft (a φ1,500 casing shaft is also possible; calculations are separate) ■ Injection of chemical solutions into the reaching section can be performed from within a φ1,500 casing pile ■ Adoption of special branches that are earthquake-resistant and watertight *For more details, please download the PDF or feel free to contact us.
