Vruddhi Sonic Tube (VST)

Method of CSL Testing

• The transmitter and receiver are placed into separate, adjacent tubes within the concrete structure.
• The transmitter sends ultrasonic pulses through the concrete to the receiver in the adjacent tube.
• The receiver detects the ultrasonic pulses that travel through the concrete.
• This process is repeated at various depths by simultaneously lowering and raising the transmitter and receiver, covering the entire depth of the concrete structure.
• This method provides insights into concrete quality and homogeneity, allowing for timely adjustments to ensure structural integrity.

About Vruddhi Sonic Tube

• Vruddhi Sonic Tubes (VST) provide a reliable method for assessing the structural integrity of concrete in deep foundation structures like diaphragm walls, bored piles, drilled shafts, concrete piles, and augercast piles.
• Made of thin steel with a bell-shaped end, VST tubes are installed within the rebar cage before concrete pouring. The bell-mouth design ensures easy connection, reducing labor costs.
• Available in various diameters, VST tubes feature a specially designed rubber gasket for simple installation and perfect sealing, preventing material entry and maintaining tube integrity.
• Using VST tubes also facilitates efficient and accurate cross-hole sonic logging (CSL) testing, providing critical data for maintaining the safety and stability of the structure.
• These features make VST tubes an essential component for quality assurance in modern construction projects.

Advantages of using Vruddhi Sonic Tubes

• No threading on pipes.
• Easy fixing to rebar cage.
• No welding required at job site.
• Fast and easy installation by labours.
•  No special equipment required for installation.
• Push-fit mark ensures full engagement, facilitating easy assembly.

Specifications

Quality Assurance

Vruddhi Sonic Tubes are Manufactured under Quality Management System – ISO 9001:2015 and tested for following test:

• Tensile test for Sonic Tubes
• Pull-out test for Ears
• Hydrostatic Pressure test
• Crush test

VST has successfully passed the above test

Storage Guidelines

• Cover steel tubes with tarpaulin.
• Store steel tubes in a covered area or enclosed container.
• Avoid exposure to environmental conditions such as humidity, rain, and heat.

Assembly Instructions

• Step 1 . Install a bottom cap onto the first sonic tube.
• Step 2 . Fix the sonic tube to the rebar cage by tying the steel wire around the fixing ears and tube.
• Step 3 . Fix the next tube to the rebar cage as the step.
• Step 4 . Connect the two tubes completely.
• Step 5 . Connect all the tubes and lower the cage. Repeat the process for all other tubes and cage segments.
