Features of ultrasonic tubes

Ultrasonic pipes of bored piles are pipes with diameter from D49 – D114 for the purpose of placing and moving the ultrasonic transducers transmitted through the testing of homogeneity of pile concrete in the ultrasonic testing of piles. Depending on the diameter of pile from D300 – D2000, different number of tubes is arranged (minimum must be 2 pipes). Ultrasonic tubes are placed in linked steel cages along the length of steel structures.

In some cases, ultrasonic pipes with a diameter of over 100 are also used for drilling to check the quality of pile head concrete and pile tip treatment.

The ultrasonic tube will be pumped into a special type of high shrinkage and shrinkage to ensure no water in. Because as the water penetrates, it can mix with aggressive substances, in the long run, affecting the quality of concrete.

Pipe laying regulations

The ultrasonic tubes are shorter than the length (usually 60cm-100cm from the bottom of the pile) and are placed into the pile before pouring concrete. Pipes must be tight, straight and continuous. The bottom of the pipe must ensure to touch or close to the bottom of the pile and be sealed with a sturdy material so that concrete cannot penetrate or lose water. The pipe joints must be firm and tight so as not to allow concrete water to enter the pipe during the pouring process. Do not use butt-welding method to connect the ultrasonic tube in case the ultrasonic tube is steel pipe. The end of the ultrasonic tube must be sealed with sturdy material. [1]

According to TCXDVN 358: 2005 “Bored piles – Ultrasonic pulse method to determine the homogeneity of concrete” guide the use of ultrasonic pulse method to assess the homogeneity of pile concrete. The ultrasonic tube is bonded to the main steel of the pile by tying or using steel bars. Connections must ensure that pipes are not moved during construction.

Ultrasonic tubes must be checked for transparency before testing. The tubes were filled with clean water 1 hour before the experiment. In case the water level in the pipe is reduced, more water must be compensated. [2]

The regulations on the number of piles to be installed with ultrasonic tubes and the number of test piles are as follows:

– When constructing test piles, all piles placed with ultrasonic pipe,

-When constructing a mass pile, the number of ultrasonic deposits is 50%, [3]

– The number of pipes for 01 pile depends on the diameter of the pile:

– Diameter of pile D≤60 cm for placing 2 pipes

– Pile diameter 60 cm ≤D ≤100 cm, 3 tubes are placed

– Diameter of pile 100 cm ≤ D with 4 tubes installed

– The distance of the pipes is from 0.3m to 1.5m.

Regarding the pile drill contact test, TCXDVN 326: 2004 regulations:

When detecting a defect, if in doubt, it is necessary to check by sampling drill and other measures decided by the design, the investor approves.

The number of preset pipes is determined by the design, refer to Table 5.
