1, disassemble Law: this method is the most complete, cleaning the best cleaning methods, but the construction is difficult, the amount of workers is also large, while the cost is relatively high.
Operation method: the distance, distance, opening position, size and number of the opening holes are measured by the technical workers and the ventilation pipes are cleaned through the holes.
Eventually, each hole is sealed. Method: this method is opening open method is relatively easy, relatively low cost, but also the cleaning effect 2, mechanical equipment: this way the easiest way of minimum ventilation pipe cleaning operation, difficulty, workload, minimum minimum cost, but also the poor cleaning effect. Cleaning cycle for the following six months of vertical ventilation pipe cleaning, this cleaning method is undoubtedly the best choice.
Method of operation: after spraying oil into the ventilation pipeline, the inner wall of the ventilation pipe of Chongqing can be cleaned by using an electric flexible shaft brush and a flexible flexible shaft brush which can extend into the ventilation pipe for up to 30 meters.
Ventilation pipe cleaning plan: the actual situation of cleaning staff skills basis to calculate the ventilation pipe, every section must distance apart ventilation pipe and extends cleaning in two directions, to ensure complete cleaning, ensure the cleaning quality.
