terms commonly used in Communications Engineering (1) cement grade: communication pipeline engineering commonly used cement grade is divided into three kinds: 1. (325# (soft practice) the soft (soft 425# practice) practice 525#) (2): ordinary concrete grade concrete grade is divided into C10, C15, C20, C25, C30 five. (see schedule per cubic metre Mix) (3) cement mortar label: , M5, , M10 and five kinds of slurry. (per cubic metre mix annex) (4): elevation measured a benchmark height level. (relative to the standard point (5) Gao Cheng: the difference between the two) elevation measured by level. (6) the standard: reference point selected measuring elevation. (7) the red line: City Road Planning for section of all kinds of underground pipelines.
2. test equipment. general provisions for communication pipeline engineering equipment specifications, procedures and quality shall be borne by the construction unit of the strict inspection before use. Found quality problems should be handled in time. All the equipment certification, after inspection found problems, should be quality technical appraisal postprocessing; where no iden
