①. Installation preparation: Be familiar with the drawings carefully, and make preparations according to the construction method determined by the construction plan and the specific measures of technical disclosure. Refer to relevant professional equipment drawings and decoration building drawings, check whether the coordinates and elevations of various pipelines are crossed, whether the space used for pipeline arrangement is reasonable, and if there is a problem, study and solve the problem with the relevant personnel of the design unit in time, and make a change and negotiation record.

Prefabrication processing: according to the design drawings, draw the construction sketches of the pipeline branch, pipe diameter, reduced diameter, reserved nozzle, valve position, etc., in the actual installation structure position

② Make a mark, measure the exact size of the actual installation according to the marked section, and record it on the construction sketch; then, check whether the pipes and accessories are supplied by the manufacturer, and after confirming that they are correct, prefabricate according to the measured size of the sketch (Broken pipes, fittings, proofreading, group numbers by pipe sections, etc.).

③, dry pipe installation

The riser shall be hoisted from top to bottom to install the clamps, and the height of the clamps near the shear wall shall be 1.8 meters, or a steel composite bracket shall be installed at the pipe well head, and the prefabricated risers shall be installed in a hierarchical order according to the number. Straighten. Temporary plugs should be installed at the branch pipes. The installation direction of the riser valve should be convenient for operation and repair. After installation, use a wire pendant to straighten it, fix it with clamps, and plug the floor hole in cooperation with the civil construction.

After leveling and alignment, use hook nails or steel nails to bind galvanized iron wires to fix the pipe ; The valve and detachable parts should be provided with inspection holes; each water distribution point should be installed with a bulkhead pipe with a length of 100mm or 150mm, and be aligned and leveled, and then perform a pressure test on the concealed pipeline. After the test is accepted, the pipe groove shall be covered with cement mortar in time.

⑤, pipeline pressure test

The concealed and insulated water supply pipes should be tested individually before being concealed, and the system should be tested after the installation of the piping system. In the hydraulic test, the internal air must be drained first, and then the water should be filled into the water pipe. The pressure is slowly increased to the specified requirement for 6 hours. There is no leakage in the first 2 hours. After 6 hours, the pressure drop does not exceed 5% of the test pressure to be qualified. The general contractor, the supervisor and the relevant personnel of Party A can be notified of the acceptance, go through the visa procedures, and then drain the water, and fill in the pipeline pressure test record in time.
