Septic dredge and drain inventory method

Dredge septic tank and drain the septic tank and inventory methods are the focus of drain inspection object, its clean smooth or not, will largely affect the quality of life of the general public, septic tanks to clear the project more complex, professional cleaning services company to clear the aspects of the pipeline has its own specific standards and processes. Drain method and construction process: 1. Check the cleaning objects: hotels, restaurants, residential sewer pipes and equipment is nothing more than the bathroom in the tub, nozzles, pots pools and pipe connections; large toilet inside the toilet, urinal and pipe connections; kitchen with sink, floor drain and connecting pipes and pipelines are connected outdoor septic tank. Before cleaning, you should first find out the ins and outs of the pipe, and learn useful life, usage, congestion, buried and exposed parts of buildings for damage and other issues. For damaged equipment and pipelines must be replaced before cleaning. In the query device pipeline, while pay attention to understand the material, in addition to iron and ceramics, but the system also what material, if cement and other construction materials equipment and piping, and system cleaning is best separated to avoid corrosion. 2. Break: the need to clean the lines into several cleaning section, this work must be done before cleaning. All kinds of buildings, the number of floors, number of units are not identical, sewers and equipment are not the same volume. To facilitate the drain, are generally divided into several smaller cleaning section, segmented approach based primarily on the level of the sewer volume, floor, easy to clean, and the possibility segment. Generally three or four floors of a unit for a period of better. 3. The closure work: This is an important part of cleaning. First, the top-down first at the blocked segment, this segment of the general observation hole pipelines (the hand hole), and then will be open to the air port and a parallel port and the other line blocking death, leaving only the two segments of the top port, a port for cleaning fluid into a port to exclude gas. When the closure work place should be able to withstand the pressure of 1-2 kg / cm 2, to avoid cleaning, leaving the closure work and sabotage since the hydrostatic liquid column. If the valve closure work place, preferably not completely rely on the valve closure work, because the valve use in a long, difficult locked, shall take appropriate measures with other closure work. 4. leak: After work is completed closure work, to conduct leak testing. Leak testing method is this: From the left of the paragraph at the top of the inlet at the Riga water, fill up the system and see if the water level drops, if dropped, find leakage at handling the leak, if maintained the water level, you can be the next step. 5. Cleaning: according to several segments into one by one from top to bottom cleaning method with the same acid water leak testing methods commonly used immersion cleaning. If the cleaning speed is too slow or stopped, not any dirt washed, may be appropriate to replace part of the cleaning fluid and continue cleaning until the wash site: http: //www.qsj96.com/index.php _m = mod_product & _a = prdlist & cap_id =? 58
