말뚝 정재하 시험 측정기 Static Load Tester (SLT)

2017_7

 

The Static Load Tester provides quick and accurate monitoring of force and displacement during a static load test. 말뚝 정재하 시험기는 말뚝시험의 응력과 변위를 볼 수 있고 저장한다.

 

Static Load Tester automatically obtains and records reliable readings at programmable load intervals during a static load test. The system allows for monitoring up to 16 independent channels taken from traditional pile-top measurements or from embedded sensors. Automatic data collection and display allows real time monitoring, analysis, and interpretation of results.

말뚝 정재하 시험기는 하중 별로 값을 자동으로 저장하고 최대 16 체널까지 측정 할 수 있다. 자동 데이터 수집 및 디스플레이를 통해 실시간 모니터링, 분석 및 결과 해석이 가능하다.

 

What is Static Load Testing? Static load testing is used to evaluate the load resistance behavior of deep foundations prior to structure construction. It differs from rapid and dynamic load testing in that the load is applied to the deep foundation slower.

정재하 시험은 구조물을 시공 전 말뚝 지지력 평가에 사용.

 

Static load tests can be performed to refine foundation design assumptions regarding the axial compression or tension resistance provided by a deep foundation element, or its response to lateral loads.
