我国多个省份开展了针对高速公路、一级公路上的交通安全设施过程质量检测。具体做法是,聘请具有综合甲级、交通工程专项资质的第三方检测单位,在交通安全设施施工过程中进行产品质量监督,检测运抵施工现场的波形梁钢护拦(包括圆立柱、护拦板和防阻块、高强度拼接螺栓连接副)、道路交通标志板、标线涂料等产品的质量,依据现行抽样标准和产品标准进行判定,最后在交工前再进行一次施工质量检测,以便于更顺利通过交工验收检测,不仅保证了工期,也避免了交工出现大量不合格情况,返工整改造成国家资源浪费和环境污染的情况。因此说高速公路开展交通安全设施过程质量控制对于交工验收检测有添砖加瓦的促进作用。
A number of provinces in our country have carried out quality inspection of traffic safety facilities on expressways and primary roads. The specific approach is to employ a third-party testing unit with comprehensive Grade A and special qualifications in traffic engineering to supervise product quality during the construction of traffic safety facilities and detect the corrugated steel barricades (including round columns and barricades Board and block block, high-strength splicing bolt connection), road traffic signs, marking paint and other products of quality, according to the current sampling standards and product standards to determine the final before delivery to conduct a construction quality inspection, in order to facilitate More smoothly through the acceptance inspection, not only to ensure the construction period, but also to avoid a large number of substandard work conditions, rework caused by the national waste of resources and environmental pollution situation. Therefore, the quality control of traffic safety facilities carried out by expressways has a positive effect on acceptance inspection.
