Piping construction "Freezing method (building)" continuous water freezing method 'DOWS method'

Piping construction "Freezing method (building)" continuous water freezing method 'DOWS method'

The basic principle is to combine it with other construction methods! The effectiveness of the combined construction methods increases, leading to a reduction in construction time.

The "DOWS method" is a technique used to assist "freezing methods" and "DSP methods" by temporarily stopping the flow of water (temporary water stopping). This method is not used alone; it is fundamentally combined with other methods. By adopting the "DOWS method," it is possible to avoid complete water stoppage, enhance the effectiveness of the combined methods, and shorten construction time. 【Features】 ■ Freezing is possible without operating existing valves ■ No concerns about damage, leaks, or discolored water due to valve operation ■ When freezing methods are applied at both ends, the area of water stoppage can be minimized ■ Installed at the section of pipe removal, leaving no saddle after construction ■ If the valve does not work and does not freeze with the "freezing method," it is also possible to apply the "DOWS method" later *For more details, please refer to the PDF document or feel free to contact us.

Salt-absorbing agent integrated rust prevention method "BR-SS Method"

Salt-absorbing agent integrated rust prevention method "BR-SS Method"

It is possible to shorten the process by using a single material! Two effects that work to suppress the corrosion of rebar within concrete can be expected.

The "BR-SS Method" is a high anti-corrosion repair method for reinforced concrete that uses a polymer cement-based anti-corrosion material mixed with a "chloride ion adsorbent" and a cross-section repair material. It adsorbs and immobilizes chloride ions that remain within the structure or are supplied from the outside, suppressing the rusting of the steel. By releasing nitrite ions, it regenerates the passive film on the surface of the rebar, further preventing rusting of the steel. This method allows for the removal of high concentrations of chloride ions, which is difficult with conventional nitrite ion-based anti-corrosion systems. 【Features】 ■ Adsorption and immobilization of chloride ions ■ Regeneration of the passive film through the release of nitrite ions ■ Double suppression using BR-SS paste and BR-SS mortar ■ Capability to remove high concentrations of chloride ions ■ Possible reduction in construction time *For more details, please refer to the PDF document or feel free to contact us.

The construction extension has reached a total of 4,930 km, boasting a high track record with the same type of advancement method.

This technology is a non-excavation small-diameter pipe jacking method that can construct various types of pipes ranging from φ150 to φ1000. Using a jacking machine installed in the launch shaft, the buried pipes are sequentially laid towards the receiving shaft, eliminating the need to excavate the road surface. Additionally, the jacking device is designed to be compact, allowing for launching from small shafts. Since it uses an excavation and soil removal method, there is no need for large surface facilities like those required for slurry methods, and the equipment associated with the work, such as cranes and generators, can be kept small, contributing to overall cost reduction. 【Features】 ■ Capable of constructing various types of pipes from φ150 to φ1000 ■ Non-excavation construction ■ Suitable for difficult ground conditions ■ Small space and low cost ■ No need to excavate the road surface *For more details, please refer to the PDF document or feel free to contact us.

Clearing a wide range of soil conditions! Introducing pipe jacking technology that takes the Earth's environment into consideration.

This technology employs a mud pressure-type excavation and discharge mechanism along with a unique position measurement system, achieving high-precision long-distance and curved advancement across a wide range of soil conditions from soft ground to bedrock. Additives are injected into the excavated soil, turning it into a slurry that is pumped up to the standing piles. By controlling the amount of mud taken in, some is left in the ground to prevent the collapse of the face and pit walls, while the lubricating effect of the mud (slurry) reduces the driving force. 【Features】 ■ Clears a wide range of soil conditions ■ Achieves long-distance and curved advancement *For more details, please refer to the PDF document or feel free to contact us.
