Our daily life without plastic pipes, plastic pipes installation construction process is how?
1. Process: prepare installation & rarr; Prefabrication & rarr; Main installation & rarr; The riser installation & rarr; Branch pipe installation & rarr; The card is fixed & rarr; The sealing plug hole & rarr; Closed water test & rarr; Water test.
2. Prefabrication: according to the drawing requirements and combined with actual situation, according to the size of obligate mouth position measuring sketch drawing processing. According to the sketch measured broken pipe plastic pipe sizes. Plastic pipe fracture to flush with milling cutter or knife to remove the fracture impalement outside edge milling out 150 Angle of inside and outside. Adhesive to socket inserted before all test shall not be inserted into the general for 3/4 of the socket depth. Try plug socket with a cotton cloth after qualified to bonding area of moisture, dust, wipe clean. If there is any oil with acetone to remove, use the brush daub glue daub socket before daub socket immediately vertical force insert, insert the adhesive turns slightly in the socket and bonding agent distribution evenly firm bonding of approximately 30 s to 1 min. Serve. Immediately after cement will overflow dope is wiped clean. When various adhesion obligate mouth direction should be paid attention to.
3. Main installation: first of all, according to the requirement of design drawing coordinates, elevation the reserved slot hole or embedded casing. Buried in the design coordinates, elevation, slope direction, slope excavation grooves and compaction. Using crane tube when installation should be according to the design coordinates, elevation, slope to do a good job, hanger. The prefabrication construction conditions have been met good plastic section according to the number shipped to the installation site for installation. When the plastic section adhesion, also must according to the bonding process. All adhesion after pipe straight, uniform slope, and obligate mouth every position accurately. Installed riser should be installed on the slip joint along from the floor or crouch 70 ~ 100 mm. Main closed water test should be done after installed, export with inflatable rubber closed leak-proof, latent water don't fall for qualified. Buried plastic pipe should be in fine sand backfill and the plastic tube epithelial 100 mm, don't touch while sift overlying soil compaction damage of plastic pipe. After hanging tube cement again according to the gradient in the direction of flow to find the last will reserve a mouth seal and plug hole.
4. Riser installation: first of all, according to the requirements of design coordinates will reserved hole or after drawing, the hole size may not be too big, more not damage reinforced. Before installation for removing pitched operation platform, according to the need to have preformed riser to the installation site. First clean has reserved expansion joints shall have preformed riser to the installation site, remove lock mother unscrewed the U type rubber ring, clear clutter. The review of the upper hole whether appropriate, vertical tube inserted into the end insert marking should first row and then coated with liquid soap set of locks and u-shaped, rubber ring. When installation will be the top riser first into a hole and vertical force insert until tag ( Generally reserved bulge drop-off for 20 ~ 30 mm) 。 Right after the box system of homemade u-shape card fastening on the slip joint along, then looking for looking for straight and measurement of roof is in line with the requirements from the center of three mouth, after having confirmed to plug holes and the upper seal (reserved slip.
5. Branch pipe installation: first picking elevator holes or review of embedded parts. Cleaning up pitched operation platform, as required. Preformed pipe according to the number to the scene and remove the adhesive parts of dirt and moisture. Preliminary lift branch level, daub binder, push into the reserve plastic pipe mouth. According to the plastic section length adjust slope after appropriate clamp frame, closed the reserve a plastic pipe mouth and plugging holes.
6. Appliance connecting pipe installation: check the building ground, metope, thickness, find out the reserved mouth coordinates, elevation and then according to the size of accurate trimming the reserved hole. The measured size do record and prefabricated parts processing, and serial number. When installing adhesive must be reserved for adhesive plastic pipe mouth is clean. Looking for positive, straight after cement, plastic pipe mouth, closed and plugging holes open the next layer of vertical pipe cleaning, with inflatable rubber closed upper closed water experiment was carried out. Qualified retreat to sealed rubber plug, sweep the mouth.
7. Plastic drainage pipe after installation according to the specified requirements must be closed water test. Anyone who is a hidden dark plastic pipe must be installed according to the breakdown process. Sanitary ware and water through ball test must be conducted after equipment installation and shall be carried out before a final cleaning paint finish.
8. Buried plastic pipe and the roof vent riser if not adopting rigid polyvinyl chloride (PVC) plastic drainage pipe fittings with cast iron pipe can use cement twisted mouth water. To prevent leakage of plastic pipe plug it with coarse sand paper burnish of plastic pipe transverse rough.
9. Adhesive volatile after use shall, from time to time block. Winter construction for glue solidification time is 2 ~ 3 min. Bonding sites should be well ventilated away from open flame.
1. Process: prepare installation & rarr; Prefabrication & rarr; Main installation & rarr; The riser installation & rarr; Branch pipe installation & rarr; The card is fixed & rarr; The sealing plug hole & rarr; Closed water test & rarr; Water test.
