The measurement of horizontal displacement of retaining walls is usually conducted by comparing it with the management standard values set from the design values, in order to manage the safety of the retaining walls. The measurement methods include automatic measurement using embedded inclinometers and manual measurement using inserted inclinometers. In both cases, guide pipes (steel square pipes 75mm x 75mm) are installed on the retaining wall, but the embedded inclinometers are buried after the installation of the retaining wall. For both measurements, the obtained measurement values (inclination angles) are multiplied by distance to convert them into horizontal displacement amounts, and by cumulatively adding from the bottom end of the retaining wall upwards, the overall deformation (distribution) is determined. Our company generally sets the installation interval for embedded inclinometers at 2 meters and the measurement interval for inserted inclinometers at 1 meter. In addition, we also conduct measurements of "cut beam axial force, ground anchor axial force," "rebound and ground subsidence," and "groundwater level." 【Regarding the setting of management standard values】 ■ Primary management standard value: Maximum displacement at the time of design × 80% ■ Secondary management standard value: Maximum displacement at the time of design × 100% *For more details, please refer to the PDF document or feel free to contact us.

The "SDVP-100LA, SDVP-100LB" is a communicating pipe type settlement gauge that utilizes the principle of "water leveling." By connecting a reference device (water tank) installed at a fixed point on a horizontal plane outside the influence range of construction with a settlement gauge installed at the measurement target (or measurement point) via a communicating pipe (hose), it detects minute pressure changes caused by the difference in water levels between the reference water surface and the water surface of the settlement gauge using a differential transformer. This detector is indispensable for measuring the deformation of existing structures due to elevated intersections and nearby construction, alongside inclinometers. 【Product Lineup】 ■SDVP-100LA (Level 160mm) ■SDVP-100LB (Level 500-3000mm) *For more details, please refer to the PDF document or feel free to contact us.

The "GS-10F, GS-10FT" is a surface strain gauge used for measuring axial forces in cut beams, steel girders, or slurry solidified column piles. A dedicated mounting foot is welded to the object being measured, and the strain gauge body is attached. Since the linear expansion coefficient of the body is manufactured to be the same as that of steel at 11.4×10^-6/℃, there is no need to correct the measurement values due to the free expansion of the steel caused by temperature changes. We also provide mounting feet (anchors) for installation on the surface of concrete. 【Features】 ■ A dedicated mounting foot is welded to the object being measured, and the strain gauge body is attached. ■ The linear expansion coefficient of the body is manufactured to be the same as that of steel at 11.4×10^-6/℃. ■ There is no need to correct the measurement values due to the free expansion of the steel caused by temperature changes. ■ Mounting feet (anchors) for installation on the surface of concrete are also available. *For more details, please refer to the PDF document or feel free to contact us.
