The spiral acoustic tube is a passage for the probe to enter the interior of the pile when the pile is subjected to ultrasonic testing. It is an important part of the ultrasonic testing system of the bored pile. Its pre-buried mode in the pile and its arrangement on the cross section of the pile will directly affect the test results.
The spiral acoustic tube is a passage for the probe to enter the interior of the pile when the pile is subjected to ultrasonic testing. It is an important part of the ultrasonic testing system of the bored pile. Its pre-buried mode in the pile and its arrangement on the cross section of the pile will directly affect the test results. Therefore, the pile to be tested should be marked with the arrangement and embedding mode of the acoustic tube at the time of design. The quality of the embedding should be strictly controlled during construction to ensure the smooth operation of the inspection.
First, the advantages of spiral acoustic tube:
1. Spiral sound tube is easy to connect, and it is connected by screw nut. It does not require preparation work outside the construction site, no equipment is needed, it is quick and easy (5 times faster than the traditional method), and it is easy to fix on the steel cage. The impact of bad weather.
2, the construction is convenient and fast, the fastest one of the spiral sound tube connection.
3. The spiral acoustic measuring tube adopts professional design method, which is 100% quality monitoring and convenient for site inspection before leaving the factory.
4. The spiral acoustic measuring tube can save the construction cost of the construction site, save a lot of preparation time on the construction site, install the construction of the spiral acoustic measuring tube without the need of technicians, and save the loss (can be customized according to customer requirements for different models) Tube), not subject to site restrictions.
5. It has the characteristics of quickness. The production of spiral acoustic tube is convenient because it can provide standard tube at any time and enter the construction site within 24 hours.
6. At the same time, the construction of the spiral acoustic measuring tube is safe, and the welding work at the construction site is avoided.
Second, the use of spiral sound tube considerations:
1. Pay attention to whether the sealing ring is in good condition.
2. The screw must be fastened in place with special tools.
3. After each section of the steel cage is lowered, the sound tube must be filled with clean water.
4. When the steel cage is lowered, the wire should be connected from the inner ring to the main rib.
5, welding steel bars do not touch the welding tongs, the ground wire to the sound tube, so as to avoid the sound tube damage caused by strong welding.
6. After the steel cage is lowered, the sound tube must be filled with clean water. Finally, cover it with a cover and enter the concrete or cement slurry.

Stop Valves are closed by screwing a rubber gasket down onto a seat in the middle of the valve. Pros only use small versions that act as shutoff valves for fixtures such as sinks and toilets and outdoor sillcocks. Flow is inefficient because of the circuitous route the fluid (water, in most cases) has to follow. It's important to orient the valve in the right direction with the arrow (cast into the side of the valve) aligned with flow direction. That way, water flows against the bottom of the rubber gasket. If the valve is put in backward, the flow will force the gasket away from the top of the valve.
