Configurable hydraulic system for static load tests on piles foundation
Static load tests are conducted to assess the pole’s vertical drops as a result of the load test.
This type of test is mandatory on a number of poles equal to the 1% of the total number of poles, with a minimum of 2.
The static load tests on foundation piles are classified into:
test projects;
evidence of testing or verification during construction.
Project tests are performed on pilot poles, equal for geometry and construction technology. The test, classified as destructive, involves an axial load that leads to rupture the complex pole-soil or it allows significant diagrams of failure of the head of the pole as a function load-time. The verification tests shall be performed mainly to control the correct execution and behaviour of the load. The axial load will therefore be equal to 1.5 times the load project.
The system includes a hydraulic pressurization unit, connection hoses, ram cylinder, swivel head. The system is configurable depending on customer’s needs, on the kind of test, on the load to reach and on the ease of transport. The pressurization system may be manual, with a control hydraulic triphase power unit or with an internal combustion engine.
