In-situ tests to understand the effects of improved ground.
The Geo-register method is a technique for quality and shape management in soft ground treatment work, which simultaneously conducts dynamic cone penetration tests and electrical logging immediately after construction to estimate the improved strength and range early on for quality and shape management.
A system composed of a three-component corn and a data recording device.
The "FP-303T" is a system for collecting data on tip resistance, lateral friction, pore water pressure, and cone penetration pressure during electric three-component cone penetration tests. During the cone penetration test, measurements are taken every 1 cm in depth to create a three-component vs. depth graph. Additionally, an excess pore water pressure dissipation test can also be conducted during the depth measurement. 【Features】 ■ Easy measurement with the connection of a three-component cone detector, encoder, and power supply ■ Measurement data is saved in CSV format ■ Can be processed with commercially available applications *For more details, please download the PDF or feel free to contact us.
Obtain a large amount of ground information in a short period! It is possible to measure sandy soils with an N value of around 30 to 50, and cohesive soils with an N value of around 20.
The "Automatic Ram Sounding Test" automatically drops a hammer weighing 63.5 kg from a height of 500 mm, recording the number of blows (Nd) required for the tip cone to penetrate 200 mm. The Nd value obtained from this test is considered to be approximately equal to the N value from the standard penetration test. Note that sample collection, as done in the standard penetration test, is not possible. Additionally, it can measure sandy soils with an N value of around 30 to 50, and cohesive soils with an N value of about 20. 【Test Machine Features】 ■ Dynamic cone penetration testing machine developed by Borro in Sweden ■ Dimensions: Height 2.8m × Width 0.8m × Depth 0.9m ■ Total machine weight: 215 kg ■ Hammer weight: 63.5 kg ■ Hammer drop height: 500 mm ■ Hammer drop frequency: 24 times/minute *For more details, please refer to the PDF document or feel free to contact us.
Tip resistance, lateral friction value, pore water pressure value, and inclination value can be measured! Data can be stored in a dedicated logger.
The product can conduct CPT tests at a speed of 0.5 cm per second while capturing images underground, allowing for real-time viewing of clear underground images thanks to a high-brightness LED light. Data can be stored in a dedicated logger, and there are two rod lengths available: 30m and 50m. Additionally, we offer the "Compact CPT Rig," which has a penetration capacity of up to 100 kN and can take reaction force with four ground anchors. 【Features】 ■ Capable of measuring tip resistance, side friction, pore water pressure, and inclination values ■ Can capture images underground while conducting CPT tests at a speed of 0.5 cm per second ■ Allows for real-time viewing of clear underground images ■ Data can be stored in a dedicated logger ■ Two rod lengths available: 30m and 50m *For more details, please refer to the PDF document or feel free to contact us.
A ground investigation method suitable for an era where surveys of 26 to 60 meters are possible!
The "Cone Penetration Test" is an in-situ testing method that allows for various assessments, including soil classification, bearing capacity, consolidation settlement, and liquefaction. By incorporating the latest electronic technology, it enables continuous and real-time acquisition of detailed ground information. Additionally, based on the relationship between cone tip resistance (qc) and cone sleeve friction (fs), it is possible to achieve soil classification without human error and to determine equivalent N values. 【Features】 ■ Continuous data collection at 2 cm intervals as standard ■ Ability to confirm thin layers approximately 2-3 cm thick ■ Enables the design of highly accurate soil structures ■ Investigation possible at a rate of 5-60 m per day ■ Data obtained without human variability *For more details, please download the PDF or feel free to contact us.
Advantageous for determining liquefaction and confirming the effectiveness of ground improvement work! It captures ground information in real-time.
We would like to introduce our "CPT" (Cone Penetration Test). The cone is inserted at a constant speed of 2 cm/s, capturing real-time ground information such as tip resistance qc, sleeve friction fs, and pore water pressure u. Data is read approximately every 2.5 cm, and automatic soil classification is performed. Compared to boring surveys that conduct standard penetration tests (SPT) every meter, the accuracy is 40 times greater. 【Features】 ■ Data is read approximately every 2.5 cm, and automatic soil classification is performed, resulting in 40 times the accuracy compared to boring surveys. ■ Investigations can be conducted at three locations per day to a depth of about 20 m, achieving 3 to 4 times the efficiency of boring surveys. ■ Liquefaction assessment using CPT complies with the "Guidelines for Structural Design of Building Foundations" (2001, Architectural Institute of Japan). * An English version of the catalog is also available for download. * For more details, please refer to the PDF materials or feel free to contact us.
Drilled through the underground rubble layer of the demolition site! Measured the deep soil bearing capacity of the uneven ground to stop excessive reinforcement, providing evidence to the client and improving the contract rate.
In housing reconstruction plans on sites of existing building demolitions or historically significant residential land, issues frequently arise due to the presence of leftover concrete debris, remnants of old foundations, and uneven backfill soil, which make it difficult to accurately determine the ground bearing capacity. Insufficient preemptive measures for obstacles can lead to construction delays after work has begun and unexpected additional costs for ground reinforcement, resulting in disputes and distrust with the client. This document details a "Ground Assessment System for Demolition Sites" that uses robust crushing and penetration of buried obstacle layers to measure the true deep support layer, thereby stopping excessive reinforcement. Utilizing GeoTech's high-penetration impact mechanism and multi-point measurement technology, we accurately visualize the deep soil bearing capacity directly beneath the foundation without being affected by surface debris. By capturing the uneven ground structure of areas like basement remnants in three dimensions, we derive the optimal foundation type (flat foundation, partial reinforcement, various piling methods) that eliminates unnecessary piling work. We provide convincing explanations to clients through objective data that combines numerical values and diagrams, strongly supporting the improvement of contract rates and profit margins.
Prevent excessive pile design in narrow steel frame buildings! Accurately identify the depth of the supporting layer with high-precision penetration tests using a compact self-propelled machine.
In newly constructed low to mid-rise steel buildings on small plots of land, the inability to accurately identify the position of the supporting layer in the ground leads to excessive reinforcement designs with unnecessary long piles, which is a factor in cost pressure. The "Automatic Ram Sounding Test" developed by Geotech uses an ultra-compact self-propelled machine to conduct high-precision surveys with great mobility even in narrow sites where large machinery cannot enter. Equipped with a dynamic penetration mechanism using a 63.5 kg hammer, it obtains continuous data up to a depth of 30 meters by penetrating hard layers with an N value exceeding 30, which cannot be excavated in SWS tests. Thanks to the surrounding friction correction function, it can calculate reliable N values equivalent to those obtained from standard penetration tests, allowing for the optimization of the specifications and lengths of foundation piles, dramatically reducing construction costs without compromising safety. The results are digitized and quickly visualized, preventing delays in structural calculations and design practices. This is an ideal ground investigation solution that achieves cost reduction for pile foundations and improved design accuracy in the construction of steel buildings on small urban plots.
