Compared with the CCTV pipeline inspection that has been popularized, the photocurable repair technology of pipeline still needs to be popularized gradually. Relying on the guidance of remediation procedures, we can understand the repair process in an all-round way. However, if you want to really master the essentials of repair work, you have to go through many field operations. The following contents are introduced." style="box-sizing: border-box">Pipeline repair system The collation of first-line engineers is a valuable experience accumulated in actual combat. It is hoped that these real dry goods will enable us to better grasp the key points and details in the large diameter solidification repair work.
Since the carrying out of the drainage pipeline maintenance work, there is a set of action plan: safety first, quality and efficiency simultaneously. Pipeline repair work is facing harsh environment, whether it is toxic gas in the pipeline, or code of conduct in construction process, may cause safety accidents. For a successful pipeline construction, safety is the first criterion, and both quality and efficiency should be grasps.
After arriving at the repair site, first go to the construction site for reconnaissance, and fully understand the external and internal environment of the pipeline. The construction environment of the central city and the suburb is different, and the operating conditions of the pipeline are different. Only by fully grasping these external factors can we be prepared for everything.
First, preparation work before restoration.
1. plugging - pumping - pretreatment (dredging and plug🦋ging), the process of this work is not explain𒐪ed here.
2. CCTV pipe robot inspection before ღand after repair (necessary equipment)
3. actually measure the size of the pipe well.
4.♏ actual measurement of length of pipe section (distance from initial well to ending well)
5. material ཧpreset (large diameter pipe is 1M on both sides of the actual pipe length).
[remarks: uܫnder the condition of water flow, bricks m🍨ust be used for sealing large diameter pipes.
Two. Repair the equipment, tools and personnel need𝓡ed.
1, technical personnel 8-10 light curing vehicle repair.
2, material transport vehicle (anti UV).
3, a windlass (5 tons 7.5KW or larger tonnage power) and downhole wire rope pulley and a well sheave and bracket over the pulley (fixed: expansion screw).
4, crane or fork lift truck (material is heavy, convenient to put in).
5, long tube respirator (downhole operation reserve).
6. Gas detector.
7, safety rope, downhole telesc꧙opic ladder 9 fan (wellhead ventilation) 10 other (bandage, forceps, wrench, screwdriver, traction rope, paper cutter, tape, waterproof, quick dry cement or plugging king, gloves, round-trip electric saw).
