seline; word-break: break-word;">a、通信管道工程所有用的器材规格、程式、及质量应满足设计文件要求和技术规范要求，并由施工单位会同建设单位或监理单位在使用前组织进场检验，发现问题或不合格的器材应及时处理；
seline; word-break: break-word;">b、凡有出厂证明的材料，经检验发现问题时，应作质量技术鉴定后由供货单位负责处理；凡质量不合格的材料或无出厂合格证明的材料，禁止在工程中使用。经过检验的器材，应做好检验记录；
seline; word-break: break-word;">c、通信塑料管道器材进场后，存放、保管、消防、安全等应满足相关标准要求；收集和抽查：及时收集器材产品合格证、生产许可证、质量检验报告等质量证明文件；并对器材料进行抽检：其数量如下表(首先是按建设单位的 材料招标文件要求抽样检查，如无特殊规定按下表执行):

seline; word-break: break-word;">1、开挖管道沟：开挖管道沟前应该先进行放线定位，坡度要求“一”字形或“U”字形。宽度要求：接管孔程式排列要求，开挖。沟是否平整，基础是否平固，底管道沟宽度是否符合要求：宽度＝管外径总和＋管间距＋管两侧预留空间。管道的埋深按设计要求开挖，如施工现场条件允许，土层坚实及地下水位低于沟底，且挖深超过3米时，应采用放坡法施工。
seline; word-break: break-word;">2、开挖好后，认真检查管沟、坑底有无砖、石等坚硬物质和其它杂物、淤泥

seline; word-break: break-word;">a、在特殊路段无法满足上述埋深要求时，当采用塑料管敷设时，若管道顶至地面距离大于0.3m时，采用混凝土水泥(C15)包封，包封厚度15～20cm。若管道顶至地面距离在小于0.3m时，必须采用无缝镀锌钢管保护。对于共建或合建的PVC管道群在特殊路段，管道群最上层管孔的顶层距地面小于0.15m而又无法使用钢管保护的应采用包。
seline; word-break: break-word;">b、封厚度大于30cm的水泥混凝土包封。
seline; word-break: break-word;">c、进入人（手）孔处的管道底部距人（手）孔底板面及管道顶部 。

seline; word-break: break-word;">
seline; word-break: break-word;">e、管道坡度应有一定的坡度，可为3‰~4‰，不得小于2.5‰，不得有向上弯曲的管道管孔：无损坏、无阻塞、无淤泥、无杂物。
