Advantages and uses of sleeve acoustic measuring tube

The telescopic acoustic tube measuring system is an embedded telescopic acoustic tube measuring system, which is used for permanent sealing of construction joints, cold joints, pipe seepage joints, floor wall gaps, etc. It is very suitable to install sleeve acoustic tubes between new and old concrete joints. The slurry injected into the embedded sleeve acoustic tube can seal the joints between construction joints, cold joints, pipe leaks and floor walls.

Sleeve type acoustic pipe measurement: one end of the steel pipe is welded with a sleeve, and the sleeve is welded and connected on site. The principle of the early products in the acoustic tube is simple, is to weld a casing on the bottom tube, the outer diameter of the casing is larger than the outer diameter of the bottom tube, and then insert the jacking tube into the casing and weld the seal. To a certain extent, the workload of on-site welding is reduced, the construction efficiency is improved, the safety of colleagues is also more guaranteed, the operation cost is reduced, and the economic benefits are increased. Sleeve acoustic measuring tube saves time and cost. Easy to operate, excellent sealing performance, strong tensile and torque resistance, vibration resistance, no leakage, no deformation, no pipe blocking. And the use method of the device: the bottom section of the reinforcement cage sound tube device: according to the requirements of the original pipe of each sound tube and the bottom pipe (pipe A) welding.

Sleeve acoustic measuring tube can be maintained. The outer diameter of sleeve acoustic measuring tube is 20mm, the inner layer is PVC pipe body, and the whole pipe body is arranged in parallel with grouting holes. In the middle is a layer of elastic rubber seal, whose function is to maintain the grout outlet. When the sleeve acoustic measuring tube is embedded in the construction joint, fine particles in concrete can be prevented from entering the tube.

The sleeve acoustic measuring tube can be opened under a certain internal pressure when grouting, so that the liquid flows out evenly, and the outer layer is reinforced braid net. Its characteristics are repeatable grouting, can also be reused, not limited by time, construction trouble free. The sleeve acoustic tube is an early product of the acoustic tube. The principle is very simple: a sleeve is welded on the bottom tube, and the outer diameter of the sleeve is larger than that of the bottom tube.

The jacking tube is inserted into the casing, welded and sealed. This is the sleeve acoustic tube, and PEG heat-shrinking plastic is added to the outside of the casing. Heat shrinkable plastic inner wall has a sealant, heated or close to the sleeve joint, increase the sealing performance of sleeve acoustic measuring tube.

Advantages of sleeve acoustic measuring tube:

1. The sleeve is used to connect the main pipe and the main pipe, which is simple and convenient, and the welding is successful in one field operation;

2. The bottom of the measuring tube adopts the one-time welding back cover technology, which has good pressure resistance and sealing performance;

3. The top of the measuring tube is equipped with external rubber cap or built-in wooden plug, which is convenient for detection;

4. Time saving, labor saving, cost saving, one-time welding success, length can be selected according to site requirements, no loss.
