Reduce testing costs! No reaction force required, easy operation, and real-time evaluation of ground bearing capacity characteristics! (NETIS registered product)

The "Simple Support Strength Measuring Device Caspol" is a tripod-type measuring instrument that can evaluate the support strength characteristics of the ground in real-time. It features simple and easy operation, minimizing individual errors, and does not require reaction force, making it applicable in narrow spaces and mountainous areas. The measurement principle involves dropping a rammer equipped with an accelerometer onto the ground, and calculating the strength constants necessary for support strength calculations of foundations and structures from the maximum impact acceleration obtained from the collision. This single device can measure K30, qc, CBR, c, and φ (converted values from impact acceleration). 【Features】 ● No reaction force is needed for loading, allowing for low-cost measurement of various parameters. ● Usable in sites where heavy machinery cannot enter, improving construction management quality. ● Measurement is quick and does not take much time. ● Compact and lightweight, easy to operate, and suitable for any tester. ● Battery-powered, enabling field measurements without worrying about power supply. ● NETIS registered product: NO.KK-980055-V ● Can calculate the "allowable bearing capacity of the ground" using measurement constants. (→ The calculation method is explained on the Marui website: http://www.marui-group.co.jp/support/caspfol.html)

Detailed information

One device measures various parameters necessary for calculating the bearing capacity of the ground. The Caspole utilizes the correlation between the "impact acceleration (Ia value)" obtained when a rammer with a built-in accelerometer strikes the ground and the ground constants, making it capable of measuring CBR, cohesion (c), internal friction angle (φ), cone index (qc), and the ground reaction coefficient (K30) obtained from plate load tests on roads.
Calculation of Allowable Support Strength Using the values of "φ" and "c" that can be measured with Caspfol, along with the "Ultimate Bearing Capacity Calculation Formula" from the Ministry of Land, Infrastructure, Transport and Tourism Notification No. 1113 and the Building Foundation Structural Design Guidelines, you can calculate the bearing capacity of the ground. The calculation procedure is available on the "Support Page" of the Marui website (http://www.marui-group.co.jp/support/caspfol.html), so please refer to it if you wish.
Scope of Construction Management by Caspol The scope of construction management by Caspol is as follows: (1) Calculation of support strength for structures with ground support strength of 294.3 (kN/m2) or less (various retaining walls and box culverts under 5m in height) (2) Calculation of support strength for the ground where crane outriggers are installed (3) Calculation of CBR value and ground reaction coefficient for road construction subgrades
The range of soil types that can be accurately measured with the Caspore is soil materials with a maximum particle size of 37.5 mm or less, and that do not contain more than 30% gravel larger than 10 mm.
