玻璃钢管作为一种新型复合材料管材，具有一定专业性，设计单位若认识不足，容易产生设计缺陷. As a new type of composite material, glass pipe is a kind of speciality, and it is easy to make design defects if the design unit is not well known. 在市政建设工程中，将土建与管材联合招标的现象屡见不鲜，由于供水管材造价较高，加上联合招标容易出现分层转包，往往导致分包单位压价采购价格低廉的劣质管材. In municipal construction engineering, civil and pipe joint bid phenomenon common occurance, because the cost of water supply pipe is higher, and joint bidding and prone to layered subcontract, often leads to purchase cheap inferior subcontractors shall demand a pipe. 科学回填对控制管道变形避免管道爆裂渗漏至关重要，若管道两侧回填 控制不好，容易导致玻璃钢管爆管事故。在回填时应加强施工监管。 The scientific backfill is critical to the control of pipe deformation to avoid the leakage of pipes, which can easily result in the tube accident of the glass tube. Construction supervision should be strengthened when backfilling. 设计中应避开地质较差区段和地震带，地基严重沉降，玻璃钢管容易发 生折裂。 The design should avoid the geological and seismic zone and the seismic belt, the foundation is seriously subsiding, and the glass tube is easily broken. 管顶活荷载对玻璃钢管的破坏比其他管材要大，浅埋<1.2 m需特别注意。 The tube top live load is bigger than the other pipes for the damage to the glass pipe, the shallow burying < 1.2 m needs special attention. 钢管和球墨铸铁管的弹性模量要远远大于玻璃钢管。由于玻璃钢管的历史并不很长，其长期性能指标（材料性能衰减）和材料离散（材质的不均匀性）特性，需要在设计、监造、接口、回填土方面做好工作，以期望达到50年的工程设计寿命。 The elastic modulus of steel tube and ductile iron pipe is much greater than that of glass tube. Due to the history of glass steel pipe is not very long, its long-term discrete performance index (material performance attenuation) and materials (material inhomogeneity) features, need in the design, supervision, interface and backfill soil to do good work, expecting to reach 50 years of engineering design life. 饮用水管道和连接密封件须经国家级相关专业认证批准。 The drinking water piping and sealing parts shall be approved by the national relevant professional certification. 管道内衬层需采用食品级环氧树脂。 The lining of the pipeline needs a food grade epoxy resin. 避免内衬层破裂，管材锯断后的玻璃纤维进入水中，污染水质，断面 没有内衬层保护也会污染水质。 Avoid the lining of the lining to break, the fiberglass that the pipe saw breaks down into water, the polluted water quality, the section without the lining layer protection also can pollute the water quality.
