*3. Principle of acoustic detection tube/Advantages of Changde acoustic detection tube
. One characteristic of the acoustic detection tube of Cangzhou Huayang Iron and Steel Co., Ltd.: it has the fastest installation speed, the simplest installation method, the best sealing performance, and tensile strength The strongest, most resistant to torque and vibration, no leakage, no deformation, no pipe blockage, the most time-saving and labor-saving acoustic pipe to install. This product does not require electricity, any technology, any tools, or any auxiliary facilities. The biggest highlight of this product is that it can be plugged in once.
.
. Two uses and one feature: This product is the latest acoustic detection tube developed by our company. It is the most mature and advanced acoustic detection tube currently on the market. The double-sealed clamp-type acoustic detection tube is the most popular in the market. Two convex grooves are designed at the end of the socket end, and the grooves are equipped with sealing rings. When installing, insert the socket end of this product into the socket end, and then use special hydraulic pliers to squeeze the two convex grooves at the same time. The pipe in the pressed part shrinks and deforms after being stressed, and the outer pipe between the two convex grooves sinks deeply into the inner pipe, thus effectively achieving a reliable connection of this product. At the same time, the rubber sealing ring deforms and fits in the The two layers of pipes play an extremely good double safety sealing role.

. 2. The installation requirements of clamp-type acoustic detection pipes, foundation pile inspection and the burial arrangement of acoustic detection pipes should comply with the regulations of /-. . The bottom of the acoustic tube should use a welded blind cover or steel plate to ensure sealing and no leakage of slurry. The acoustic tube can be directly fixed on the inside of the steel cage. The distance between the fixed points is generally no more than 1. The bottom end of the acoustic tube and the joint part should be set with fixed points. For parts without a steel cage, the acoustic tube can be fixed with steel brackets. The fixation method can be welding or banding. When welding is used, it should be avoided to burn through the acoustic tube or form welding lesions on the inner wall of the tube, which will affect the straightness of the acoustic tube. 2. The steel cage should be prevented from being twisted when placed in the pile hole. The acoustic pipe is generally installed in sections along with the steel cage. Clean water should be added to the acoustic pipe at each buried section. After the installation of the acoustic pipe, the upper opening should be capped or plugged to prevent foreign objects from falling into the hole when pouring concrete, causing the hole to be blocked. . The buried depth of the acoustic detection tube should be - above the bottom of the cast-in-place pile, and the upper end of the acoustic detection tube should be 3~ higher than the top surface of the cast-in-place pile. The exposed height of the acoustic detection tube on the same pile should be the same. . Before pouring underwater concrete for foundation piles, the water level in the acoustic tube should be checked. If the water in the tube is not full, it should be refilled. . If the acoustic detection tube needs to be cut off, it should be cut with a cutting machine. After cutting, the tube mouth should be polished to eliminate internal and external burrs. It is not suitable to burn it off by electric welding. . When welding steel bars, avoid splashing the welding fluid onto the acoustic tube body or joints.
