铁路声屏障主体工程工艺流程及质量控制要点:

一、 工艺流程 
声屏障主体工程采用安装基础检查→H型立柱安装→立柱调整→重力式砂浆灌注→铝合金单元板安装→检查是否合格→接地连接的施工工序。

二、质量控制要点 
①H型钢柱的安装前,先再次检查、校正预埋地脚螺栓位置、外露长度、丝扣完好情况;后安装下部薄螺母、弹性垫圈、上部薄螺母,下部薄螺母须拧紧,上部薄螺母顶面调整至与底梁顶面同高。 安装就位后拧紧高强螺栓,拧紧高强螺栓应采用配套扳手,避免超拧欠拧现象,为避免螺母丢失,同侧的螺母须进行电焊点固。安装过程中须随时检查立柱的垂直度、相邻立柱间距,如有超限及时调整。 
(1) Before installing H-shaped steel column, check and correct the position, exposed length and screw-in condition of pre-buried anchor bolts; then install thin nuts at the lower part, elastic washers and upper thin nuts at the lower part, tighten the thin nuts at the lower part, and adjust the top of the thin nuts at the same height as the top of the bottom beam. After installation, tighten the high-strength bolt, tighten the high-strength bolt should adopt matching wrench to avoid over-tightening and under-tightening. In order to avoid nut loss, the same side of the nut must be soldered by electric solder joint. During installation, the perpendicularity of the column and the distance between adjacent columns should be checked at any time.

声屏障

②声屏障单元板采用插装的方式,人工安装由上往下逐块插入,安装时两端须同时缓缓插入。安装前底部须安装解耦装置,单元板与单元板之间须加垫三元乙丙橡胶垫, 安装时须注意吸声板的朝向和上下位置的正确性。

③路基声屏障接地采取在最上面一块单元板上部扣压一根镀锌扁钢,并通过自攻螺栓与单元板相连后,两侧用70mm2铜导线连入接地系统,安装完成后进行接地测试,保证接地良好。 
(3) The grounding of roadbed noise barrier is made by buckling a galvanized flat steel on the top of the unit board, connecting the unit board with self-tapping bolts, and connecting the two sides with 70mm2 copper wire to the grounding system. After installation, the grounding test is carried out to ensure good grounding.
