Asphalt mat

Asphalt mats that protect harbors and coastlines from disasters.

The asphalt mat is formed by embedding reinforcing core materials, lifting wire ropes, and lifting fittings within asphalt aggregate. It is widely used in hydraulic structures from rivers and coastlines to oceans, and can also be used for prevention of permeability, slope protection, water cutoff works, and anchoring measures. 【Main Uses】 ■ For Increasing Friction - By installing it between caissons, block walls, etc., and the riprap, it is possible to use a friction coefficient of 0.8, allowing for a reduction in cross-sectional width. ■ For Erosion Prevention - It can bend into the slopes of erosion holes that occur on the front and back surfaces of riprap mounds and wave-dissipating blocks in ports and coastal structures, stopping the progression of erosion. ■ For Preventing Suction - It can be laid on the bottom surfaces of riprap mounds and wave-dissipating blocks to prevent the suction of bottom materials (sand). - It can be laid on the back side of riprap mounds for reclaimed shorelines to prevent the loss of backfill materials due to suction. *For more details, please download the PDF or contact us.

Static load test of the Fukure Bridge and investigation of the vertical bearing capacity of the piles.

To check for daily fluctuations, automatic measurements will be conducted for about one week before and one week after the static load test!

A "static load test" was conducted to understand the bearing capacity of the P3 pier. The Fukurai Bridge is a road bridge spanning Fukuni Street in Joso City, Ibaraki Prefecture, and repair work is planned due to the settlement of the P3 pier caused by the Great East Japan Earthquake. The measurement of the pier's settlement was carried out using a communicating pipe type displacement gauge, and the tilt angle was measured with a stationary two-axis inclinometer. The load was applied by placing a plastic tank on the P3 pier and pumping water from the river to reach up to 60 kN in increments of 10 kN. 【Test Overview】 ■ The measurement of the pier's settlement was conducted using a communicating pipe type displacement gauge, and the tilt angle was measured with a stationary two-axis inclinometer. ■ The load was applied by placing a plastic tank on the P3 pier and pumping water from the river to reach up to 60 kN in increments of 10 kN. ■ The vertical displacement of the P3 pier and the two-axis (X, Y) tilt were measured at this time. ■ To confirm daily fluctuations, automatic measurements were conducted for about one week before and one week after the static load test. *For more details, please download the PDF or feel free to contact us.

Ground Penetrating Radar Survey Service

Investigation of voids and looseness, diagnosis of structural deterioration, and investigation of underground buried pipes.

Our company conducts surveys using ground-penetrating radar. Ground-penetrating radar is a exploration method that utilizes the property of electromagnetic waves to reflect when they encounter materials with different electrical characteristics while propagating through the air or underground. By emitting electromagnetic waves from the surface or within a borehole into the ground (or within a structure) and analyzing the reflections from the target objects, we can determine the locations of underground cavities, water accumulations, buried pipes such as water and gas lines, rebar within building walls, and geological boundaries. [Examples of Use] ■ Investigation of cavities and looseness ■ Diagnosis of structural deterioration ■ Survey of underground buried pipes *For more details, please download the PDF or feel free to contact us.

【Q&A】Review of Explosion-Proof Areas through Detailed Risk Assessment

We would like to review the explosion-proof area, and we have summarized frequently asked questions regarding feasibility, evaluation methods, and other related topics. Please use this as internal reference material.

Many companies are looking to: - Expand the use of smartphones and tablets - Increase the installation range of sensors and cameras, etc. By utilizing the latest digital devices, they are undertaking various initiatives aimed at improving operational efficiency and addressing labor shortages. In this process, we strongly support the promotion of various initiatives by meticulously reviewing explosion-proof areas. In this Q&A, we will answer questions that many companies want to resolve regarding actual risk assessments.
