Construction process measurement is mainly determined bottom elevation after mechanical excavation, using measurements with the machine, with the digging measure to eliminate the phenomenon of over-excavation, the bottom elevation to ensure compliance with the design requirements, the pipeline installation, retest, found deal with the problem in a timely manner, so that the tube bottom elevation controlled within tolerance range. Measured daily before work begins, the standard of review should be carried out adjacent to the measurement. Pipeline control center by the middle pile to determine, by controlling the pile play sideline pvc bellows in the pipeline on the basis of criteria to determine the location of the pipeline laying. Well elevation control room design requirements, after the pipeline is completed, the need for the completion of the review of the measuring tube top and structures. Trench excavation and foundation treatment: Xiong Wong Tai plastic case of groundwater, when the trench excavation, set up drains, sumps pvc bellows, in a timely manner within the trench underground drainage work Xiong pvc corrugated precipitation tube and take Xianpu pebbles or gravel layer (thickness not less than 100mm) foundation reinforcement measures; when there is no groundwater pvc corrugated pipe manufacturers, prime soil solid foundation, the compaction factor greater than 0.95; when the case of mud, miscellaneous fill When the soft soil, etc., according to the pipeline processing requires grading Gobi Territory Replacement processing; Replacement thickness of 30cm. Meters around the trench excavation, earthwork Sinotrans artificial groove after clearing and inspection by the supervising engineer before proceeding to the next process of construction in the groove.
