Low-altitude head-down-the-hole hammer method LH-DH method

Low-altitude head-down-the-hole hammer method LH-DH method

Down-the-hole hammer method under low ceilings, under bridges for railways and roads, and under power lines!

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.

Low-profile casing conveyance down-the-hole hammer method LH-CDH

Low-profile casing conveyance down-the-hole hammer method LH-CDH

Low-altitude, under-bridge, under-railroad, under-road bridge, and under-power-line casing conveyance type down-the-hole hammer method!

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.

RPR coating removal

RPR coating removal

We will safely remove the coating with consideration for the environment.

"RPR Coating Removal" is a new method that significantly improves the working environment, safety, and efficiency compared to conventional methods in the process of coating peeling and removal. In this method, heat generated on the surface of the steel plate is utilized through electromagnetic induction heating (IH) to peel off the coating on the steel plate surface. Additionally, it is effective for the removal of hot coating films over 500μm thick, thickly applied paint films, rubber linings, and FRP linings, which are difficult to remove with other methods. [Advantages] ■ Designed with consideration for the health and safety of workers ■ Generates almost no dust and does not scatter paint films ■ Particularly low waste compared to existing methods *For more details, please download the PDF or feel free to contact us.

Instant curing coating method "Swael® Water Supply System"

Instant curing coating method "Swael® Water Supply System"

No foaming occurs due to humidity, and it hardens completely even at sub-zero temperatures (below -15°C).

The "Swael® Potable Water [Corrosion and Waterproofing] System" is a revolutionary instant curing coating system developed for corrosion and waterproofing of concrete structures for potable water, based on a two-component polyurea resin (product name: Swael) consisting of isocyanate and a special curing agent, and a spray technology that mixes and ejects these two components. The gel time after spraying is extremely short, just a few seconds, allowing for walking on horizontal surfaces after 30 seconds. Therefore, the curing time after construction can also be shortened. Additionally, due to the short gel time, it is easy to apply thick coatings continuously on ceiling and wall surfaces without sagging, allowing for quick and efficient construction. [Features] ■ Instant curing ■ Cures regardless of humidity and temperature ■ Improved efficiency with a mechanical construction system ■ Excellent workability on ceiling and wall surfaces *For more details, please download the PDF or feel free to contact us.

Spring Bit Method

Spring Bit Method

Anchor installation that provides three times the strength even at shallow depths.

The "Spring Bit Method" is a technique that allows for high adhesion by creating uneven surfaces on the inner walls of a core hole when the core drilling for post-installed anchors interferes with existing rebar. This method ensures pull-out strength even with a short embedment length (for example, reducing from 15D to about 8D). It is applicable to all types of construction that involve core drilling using core boring equipment for post-installed anchor work. Please feel free to contact us if you have any inquiries. 【Features of Spring Bit Products】 ■ Special blades using diamond chips for core boring and similar applications ■ Utilizes spring stress to create a ring-shaped groove inside existing holes ■ If existing rebar is encountered at depths where rebar detection does not reach during anchor drilling, this blade can be used to create grooves inside the hole to enhance pull-out strength, achieving equivalent anchoring power even if the required embedment length is not reached. *For more details, please download the PDF or feel free to contact us.

Shield and propulsion shaft construction <Hayak pressure-in caisson method>

There are many achievements in shield and propulsion shaft construction.

We would like to introduce the "shaft construction for shield and thrust" utilizing our "Hayak Pressure-in Caisson Method." Shield construction planned in urban civil engineering often requires deep excavation to avoid existing underground structures such as subways and water pipelines. As a result, the adoption of the pressure-in caisson method is increasing, considering the impact on the surrounding area and safety. [Features] <Shaft Construction> ■ Capable of constructing deep and large-diameter shafts ■ Most of the work can be done from the ground, which is advantageous in terms of safety and cost *For more details, please download the PDF or feel free to contact us.

Lift-up horizontal rotation construction method

Lift-up horizontal rotation construction method

It is possible to install bridge piers under strict construction restrictions such as upper limits, lateral limits, and front limits.

The "Lift-Up Horizontal Rotation Construction Method" involves lifting up the pier and beam section, and then rotating it horizontally after connecting it to the columns. This method allows for the installation of piers under elevated bridges in construction conditions where there are strict limitations above, to the sides, and in front, such as those found in areas squeezed between roads. Please feel free to contact us if you have any inquiries. 【Features】 ■ Construction can be done with low noise ■ Significant reduction in traffic restrictions ■ Reduction of high-altitude work is possible ■ Shortening of construction period is possible *For more details, please download the PDF or feel free to contact us.
