5.4 Key points of operation
5.4.1 When the air line is connected, the air hose and the air compressor. The connection between the air dryer and the air delivery valve must be checked with a steel wire locomotive with a diameter of 41m. 5.4.2 Before installing the receiving device, check whether the re-impedance is firmly connected. When installing the sending device and the receiving device, the original barrier layer or the end of the construction pipe section must not be damaged.
5.4.3 An electronic positioning transmitter should be installed in the pipe cleaner, and its power supply voltage should be checked before installation.
5.4.4 During the pipe cleaning operation: the travel speed of the pipe cleaner should be controlled at about [m/s. 5.4.5 The quality standard achieved by the pipe cleaning operation is to remove debris such as mud, wood, mix, and water inside the construction pipe section, and make the inner surface of the construction pipe dry. For the construction pipe section with dry coal inside, the pipe cleaning operation should be carried out once. When there is mud and water in the construction pipe section, the pipe must be cleaned several times until all the mud and water are cleared out, and the inner surface of the construction pipe section should be blown dry with compressed air. 5.4.6 During the pipe cleaning operation, when the gauge pressure reaches 0.When the pipe is stuck for more than 4M, it should be considered that the pipe cleaner is stuck. After the blocking phenomenon occurs, it is advisable to install another pipe cleaner and perform the pipe cleaning operation again. If the blocking occurs again, the construction personnel shall carry the electronic positioning receiver to find the exact position of the pipe cleaner: and use the fire sticky cutter to cut the construction pipe section outside the welding heat shadow area in front of the pipe cleaner to eliminate the blocking fault. After the friction is eliminated, the pipe cleaner should be placed outside the welding heat affected zone of the fracture surface to repair the fracture, and the outer anti-separation layer at the fracture should be patched with the same or compatible material and the same structure as the outer anti-separation layer of the construction pipe section. Only after the above operations are completed can the pipe cleaning operation of the construction pipe section be continued. 5.4.7 After the pipe cleaning operation is completed, if the inner surface rust is not removed immediately, the sending end and the receiving end should be sealed well, and water is strictly prohibited from entering. 6 Removal of the inner surface of the construction pipe section

Note: The rust remover is made of straight wire, the copper wire is processed by night stock, and the solution can be matched with the electronic room. The outer diameter of the pin should be 1mm larger than the inner diameter of the solution. 622 The job setting and personnel allocation of the inner surface rust removal process can refer to the provisions of Table 5,2.2 of this standard.
6.3 Plane layout
631 The layout of the inner surface cleaning process, except replacing the pipe cleaner with a cleaning device, shall comply with the provisions of 5.3.1 of this standard. 6.4 Key points of operation
6.4! An electronic positioning transmitter shall be installed in the derusting device, and its power supply voltage shall be checked before installation. It can only be used after the power supply voltage reaches the rated value. 6.4.2 Before installing the derusting pusher into the transmitter, it must be controlled on the outer diameter of the steel wire.
6.4.3 During the inner surface derusting operation, the travel speed of the derusting pusher should be controlled at 0.5-1.0m/s
The inner surface derusting should be carried out multiple times. The rust removal level should reach ST2 level specified in "Rust Level and Rust Removal Level of Steel Surface before Painting". Method: Check the inner surface of both ends of the construction pipe section against the standard photos in "Rust Level and Rust Removal Level of Steel Surface before Painting". 6.4.4 After the inner surface is rusted, if it is not immediately rinsed and wetted, the two sides of the construction pipe section should be sealed to prevent dirt, water, etc. from entering.
