Measurable even in areas where heavy machinery cannot enter! "Simple Bearing Capacity Tester Caspol"
MIS-244-0-62 type
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, minimizes 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 the foundation support strength of 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 required 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. ● Powered by batteries, enabling field measurements without worrying about power supply. ● NETIS registered product: NO.KK-980055-V ● Can calculate the "allowable support strength of the ground" using measurement constants.

Detailed information
-
A single unit 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 an accelerometer built-in strikes the ground and the ground constants, making it an excellent tool 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 bearing capacity for structures with a ground bearing capacity of 294.3 (kN/m²) or less (various retaining walls and box culverts under 5m in height) (2) Calculation of bearing capacity for the ground where crane outriggers are installed (3) Calculation of CBR values and ground reaction coefficients for road construction
-
Soil type range The soil type that can be accurately measured with the Caspore is soil material with a maximum particle size of 37.5 mm or less and containing no more than 30% gravel larger than 10 mm.
