Connection Principle of Clamp-type Acoustic Detection Tube There is a convex groove at the socket end of the clamp-type acoustic detection tube with rubber inside. When installing the sealing ring, insert the socket end of the sound side pipe into the socket end to the marking position, and use special hydraulic pliers to simultaneously squeeze the groove and one side of the groove. The rubber sealing ring will act as a seal after being squeezed. , the pipe at the socket and socket end of the clamping part shrinks and deforms at the same time (the cross-section forms a hexagonal shape for positioning and fixing, thus effectively realizing the connection of the acoustic side pipe. The sealing principle is that the rubber ring shrinks radially and holds tightly. The anti-pull-out principle is clamped The part is deformed, the middle is small and the two ends are large. The principle of rotation is used to clamp into a hexagonal shape and cannot be rotated. Features: The sealing rubber ring shrinks radially after extrusion and holds the insertion end of the sound side tube until it is deformed, which has excellent sealing performance. The anti-vibration clamp-type joint seals the connection part at one time, avoiding the possibility of the loose joint. The anti-pull-out clamp part deforms, becomes smaller in the middle, and is larger than the two ends, and has excellent pull-out resistance. The torsion-resistant clamping part is in a hexagonal shape so that the sound-side pipes cannot slide relative to each other after being connected. The bending-resistant connection part does no harm to the steel pipe itself, and there is a socket that is twice the diameter of the pipe at the joint. The convex joint is the largest The diameter is less than or equal to our pipe diameter. The verticality is due to the socket of twice the pipe diameter at the joint, which can well ensure the straightness of the connection. The operational performance saves time, effort and cost, and the installation is successful in one time. Economical without short pipes The head is wasted and the total cost is lower.
Advantages of clamp-on acoustic tube
Reliable and safe clamp-on connection, high strength, good vibration resistance, safe and reliable, the connection part is pressed once, avoiding loosening of the loose joint possibility.
The joint has the smallest convex section and the largest convex section, and is connected in an arc, effectively avoiding collision with the pipe and minimizing the concrete flow resistance.
Convenient and quick construction to avoid on-site welding of wires Or rolling groove operation, as long as a special clamping tool is used, the clamping connection can be easily completed, saving time, effort and cost, and the installation is successful in one time
Double-head double-sealed clamping type acoustic pipe and spiral acoustic testing Pipes (flange-type acoustic pipe products comply with the industry standard "Steel Thin-walled Acoustic Pipes and Usage Requirements for Concrete Grouting Piles" which was piloted by the Ministry of Communications of the People's Republic of China on January 1, 2020, that is, the national standard implementation standard (/). Various types of acoustic pipes produced by our factory The specifications of the acoustic detection tube not only meet the requirements of the standard, but also each indicator has been greatly improved, and obtained the inspection qualification report from the Hebei Daoqiao Inspection Center
The four detection tube top cages are installed
on the top of the steel bars After the cage is installed, all joints of the detection pipes are connected to ensure that the clamps are firm. The detection pipes must be filled with clean water, and finally the special heads are screwed on. All operations are completed
The five detection pipes are installed as half cages on the pile foundation. When
The detection pipe can be welded and positioned in sections according to the actual situation to facilitate the positioning of steel hoops. It can also be installed without a steel cage. Compared with other connection joints, it can save vertical steel bars and is safe and convenient< br/>
