We would like to introduce our "Low-Headroom Casing Continuous Down-the-Hole Hammer Method LH-CDH Method." By using a special bit and continuously installing protective steel pipes for the borehole walls, we can reliably excavate to the designed height even in collapsed layers with high groundwater levels. After excavation, the steel pipes are left in place, allowing for the extraction of the hammer bit, which ensures that core material installation and solidification with mortar can be carried out effectively. Please feel free to consult us when you need our services. 【Construction Examples (Partial)】 ■ LH-CDH Method - Height restriction: 4.55m (under highway bridge) - Steel material: H300 L=11.5m continuous pile construction - Construction machinery: RX2300 low-headroom construction machine HGS60 *For more details, please download the PDF or feel free to contact us.

We would like to introduce our "Low-Headroom Down-the-Hole Hammer Method LH-DH Method." Using a driving device to rotate the down-the-hole hammer and bit, the piston inside the hammer cylinder is moved back and forth by air supplied from a high-pressure compressor. This movement causes the bit tip to strike and break stones and rock formations, while the excavated soil is removed using a screw and air lift method. To prevent wear and seizure inside the cylinder due to piston movement, it is necessary to spray oil into the air using a line oiler. 【Construction Examples (Partial)】 ■ LH-DH Method ・Height restriction: 4.55m (under special high-voltage lines) ・Steel material: H250 L=7.5 to 9.5m joint pile construction ・Construction machinery: RX2300 low-headroom construction machine, special auger for low headroom AGD7000 *For more details, please download the PDF or feel free to contact us.

• Ground foundation construction method

The "Low Headroom Double R Method LH-RR Method" enables construction in high N-value layers such as soft rock and gravel with low vibration and low noise using small foundation machinery. Traditionally, ground that required large foundation machinery can now be constructed using a leaderless pile driving machine weighing between 20t and 40t, equipped with a high torque auger ranging from 70.7 to 98kNm, utilizing main body pressure input and a special auger head for hard ground. Additionally, the removal of obstacles and crushing methods underground can also be performed by changing attachments. 【Low Headroom Special Auger Performance (Partial)】 ■ Auger Type: AGD7000 ■ Weight (kg): 1,720 ■ Operating Pressure/Flow Rate: 27.4Mpa・220l/min ■ Base Machine Used: Hitachi Construction Machinery RX2300・SRX2700・RX3300 Low Headroom Dedicated Machines *For more details, please download the PDF or feel free to contact us.

• Ground foundation construction method

We would like to introduce the "Low-Head Type Rigid Ground Pile Driving Method LH Method" proposed by Go Plus Co., Ltd. This method is particularly suitable for construction on rigid ground under height restrictions (H = 4.0 to 8.0). It demonstrates its effectiveness in many challenging sites, such as "installing steel sheet piles in the rock and boulder layer under a bridge pier foundation at a height of 5.0m" and "installing H-shaped steel into the bedrock under overhead lines at a height of 5.0m." 【Method Classification】 ■ LH-RR Method ■ LH-DH Method ■ LH-CDH Method ■ CHV Method (can be used in combination with LH methods) *For more details, please download the PDF or feel free to contact us.
