Pavement

In order to maintain and repair the road efficiently, it is essential to make a structural evaluation of existed pavement properly. Drilling machine which can investigate the paved structure easily due to the spread of FWD test investgating bearing capacity or residual Ta of the pavement with non-destructive measure is required.

Small capacity drill (TTSD) Portable

TTSD-01C drill is a portable survey drill being designed and manufactured based on the requirement from our customers. This drill is powered by 100 V generator and mounted on a carrier to enable smooth movement during transportation or on the road. By the use of dual tube type core barrel, the sample with nearly original thickness of asphalt mixture, granulated crushed-stone roadbed or subsoil can be collected without the disturbance by circulation fluid.

We can offer the equipment with "Only One" features upon customer's request.

Small capacity drill (EP-10LH) Low head rotary and vibration

EP-10LH Drill is a compact low-head drill with both of rotation and vibration mechanism being designed and manufactured based on the requirement from our customers. Drilling efficiency is remarkably improved by means of an innovative mechanism for drilling by giving both of rotation and vibration to drill bit and this drill becomes a popular model being friendly to neighboring environment because of creating low noise.
This drill is capable of high speed sampling without use of circulation fluid for about 1 meter depth and also capable of dual pipe sampling method in case the sampling of soft ground or deeper sampling is required. The height of drill during operation is 2.3 meters to meet low headroom requirement and the operation under various working conditions is possible.

We can offer the equipment with "Only One" features upon customer's request.

Radioactive decontamination

Under the incidence of Fukushima nuclear power plant accident by the Great East Japan Earthquake, a proper decontamination based on radiological dosage is carried out according to decontamination action plan in the area designated as Special Area for Decontamination. Decontamination methods with rationally available technologies are taken .

Large capacity drill (RSC) Surface scraping of farmland

Based on Act on special measure concerning the countermeasure for radioactive contamination and the basic policy made by the cabinet decision followed by this Act in 2011, the initiative for decontamination under the responsibility of the government has been taken. Long-term proper measure is planned in order to aim the additional radiation dose less than 1mSv/year after 2014.
RSC-200 is the machine to scrape surface soil with 5 - 10 cm thicknee at farmland and to load the contaminated soil into a tonpack located at the rear of machine using belt conveyor. This machine has been used for decontamination work of farmland in Iidate Village designated as Special Area for Decontamination since 2012.

We can offer the equipment with "Only One" features upon customer's request.

Aseismic reinforcement

Japan is a country subject to frequent earthquakes and the urgent provision of construction for aseismic reinforced wharf in order to secure the transportation of relief supplies and business activities at the incidence of Tokai, Tonankai and Nankai Earthquakes is required.

Large size drill (Ein Band Drill) Rotary Percussion

Based on "Program for Urgent Wharf Aseismic Reinforcement and Improvement" settled by Ministry of Land, Infrastructure, Transport and Tourism on March, 2006, only approx. 66% of wharves have been improved by 2010. Furthermore, after the incidence of the Great East Japan Earthquake in 2011, deep-draft ships such as ferry and roll-on/roll-off ship have been active for the tranportion of urgent relief supplies and the necessity of aseismic reinforcement of wharves to accommodate such ships is re-recognized.
"Ein Band Drill" is a hydraulic rotary percussion drill with enough feed force to install a long anchor, and with powerful percussive energy to penetrate through caisson base and embedded stone at base mouond behind the caisson for harbor aseismic reinforcement anchoring.

We can offer the equipment with "Only One" features upon customer's request.
