The low strain method, acoustic transmission method and thermal anomaly pile integrity test method were used on the same pile for integrity detection and comparison.
Through carrying capacity test of test piles, determining the time-history curve of soil resistance recovery and optimizing the design scheme of pile foundation can save a lot of engineering costs.
The offshore wind power steel pipe pile foundation has the characteristics of high bearing capacity, large construction equipment and high cost. How to reduce uncertain factors as much as possible during the design and construction process to avoid losses caused by program changes and construction stagnation?
High strain? Low strain? Static load? Ultrasound? I only know these kinds of pile integrity test methods, you are out ~
The sediment thickness at the bottom of the hole is one of the main factors affecting the bearing capacity of the cast-in-place pile. The SQUID borehole pile sediment thickness detector is used to measure the thickness of the bottom of the hole and the bearing capacity of the soil layer at the end of the pile, providing engineers with quantitative data.
Do friends really know the common detection methods? How should these methods be chosen? What are the advantages and disadvantages?
The foundation is an underground concealed project, and there are many unsafe factors. It is difficult to fully understand its condition after the completion of the building, and accidents that occur during the use of the building are difficult to detect in advance. Therefore, once an accident occurs, it is difficult to remedy and even cause disaster.
