Product Basic Information
Quality Assurance
Test whether the quality of the double wall bellows meets the national requirements, the most important method is to use the ring stiffness and ring flexibility test.The plastic pipe ring flexibility testing machine is used to test whether the pipe conforms to GB/T 9647 (ring stiffness determination standard) thermoplastic pipe ring stiffness and ring flexibility meet the national requirements.The experiment is mainly used for buried drainage of polyethylene double-wall bellows, buried drainage of hard polyvinyl chloride PVC-U structure wall pipe system,Polyethylene winding structure wall pipe, communication plastic pipe (solid wall pipe, silicon core pipe, plum-flower pipe, double wall corrugated pipe, prestressed concrete bridge plastic corrugated pipe, insulation pipe, carbon pipe, buried gas polyethylene pipe, polyethylene and PVC pipe used in underground coal mine ring flexibility, ring stiffness determination.
Construction Plan
1. Be familiar with the design drawings and , and make clear the pipeline layout, direction, process flow and construction and installation requirements of the supervisor and branch pipes.
2. Be familiar with the site situation and the distribution of existing plane and elevation control points along the designed pipeline.
3. Collect the measured data and draw the measured sketch according to the pipeline plane and the existing control points, combined with the actual terrain.
4. After the entry of the transition of construction units leveling points and traverse points for retest, after closure comply with the design requirements, traverse points, leveling points of encryption, each 60 meters a worldwide level points, encryption point must be closed adjustment, leveling point L closure of 20), ensure the accuracy of the encryption points, in order to meet the drain height, the precision of the linear control.
5. Because the Central Line pile of the pipeline will be removed during construction, the construction control pile should be set up in a place free from construction interference, convenient for testing and easy to protect. The Central Line direction control pile should be tested by the extension line or wire method, the position control pile of auxiliary structures should be tested by the intersection method or parallel line method.
6. The measurement in the construction process is mainly to determine the elevation of the bottom of the trough. After mechanical excavation, the following machine is used to measure and measure as the excavation is carried out to eliminate the overdigging phenomenon and ensure that the elevation of the bottom of the trough meets the design requirements.Every day before the start of the survey work, the adjacent level should be checked measurement.
7. The center of the pipeline is determined by the control pile of the center line. The edge line is drawn on the foundation of the pipeline by the control pile to determine the laying position of the pipeline.
8. The well chamber elevation shall be controlled according to the design requirements. After the pipe laying is completed, the pipe roof and structures shall be re-checked and measured upon completion.
