The "PIT Method" is a swinging pressure-insertion shaft construction machine that minimizes manual work underground, allowing for easier safety management as the manual work is conducted above ground. Since excavation can proceed while securely retaining the soil with casing, there is no concern about ground collapse or pavement subsidence. 【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 "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 soil retention 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 push of PVC pipes using the "Urinbo" method. 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 for easy maintenance - Suitable for locations that cannot be constructed without human power, such as fences, hedges, within residential land, indoors, and areas with elevation differences - No risk of ground collapse 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 advancement technique that utilizes a combined auger and pressure insertion method to achieve 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 heavily trafficked 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 ■ φ2,000 casing shaft initiation (φ1,500 casing shaft initiation is also possible; separate calculations apply) ■ Chemical solution injection to the reach section can be performed from within a φ1,500 casing pile ■ Adoption of special branch pipes that are earthquake-resistant and watertight *For more details, please download the PDF or feel free to contact us.
