                            高速路桥梁孔道压浆与质量控制

                            时间:2020-05-06 10:35作者:王佳 段薛鹏
                            本文导读:这是一篇关于高速路桥梁孔道压浆与质量控制的文章,本文以清远市内南北走向的清西大桥为例。该路桥连接广清高速与清连高速,桥梁长达3.8 km。全线包含了3座小桥、1座中桥、3座大桥、3座互通式立交桥、10座匝道桥及18座通道。

                              摘    要: 由于桥梁工程内预应力筋受到高应力的影响极易被腐蚀,从而影响整个工程的质量。要想避免预应力筋受到腐蚀,就必须注重孔道灌浆工序的质量控制。本文以清西大桥工程为例,充分准备好孔道压浆所需要的设备及材料,采用LJ-YJA系列大循环智能压浆设施,并对压浆材料进行改造,合理确定各材料比例,进而对孔道压浆及质量控制过程展开详细的探讨,提出几点质量控制措施,如在钢绞线穿束时必须保证孔道中杂物已被完全清除等,最终取得了良好的施工效果。

                              Abstract: Because the prestressed tendons in the bridge project are affected by high stress,they are easily corroded,which affects the quality of the entire project.In order to avoid corrosion of the prestressed tendons,it is necessary to pay attention to the quality control of the channel grouting process.This article takes the Qingxi Bridge project as an example,fully prepares the equipment and materials required for grouting in the tunnel,adopts the LJ-YJA series large-cycle intelligent grouting facilities,and reforms the grouting materials to determine the proportion of each material reasonably,and The tunnel grouting and quality control process were discussed in detail,and several quality control measures were put forward,such as the need to ensure that debris in the tunnel has been completely removed when the stranded wires pass through the bundle,and finally achieved a good construction effect.
