Highway tunnel inverted arch replacement construction method
The invention relates to a highway tunnel inverted arch replacement construction method. The method comprises the following steps of dividing a tunnel into a first part and a second part according to the center line of a highway in the tunnel; dismantling ancillary facilities of the first part, grouting the bottom of a side wall of the first part, paving a temporary pavement at the bottom of the side wall, and widening the pavement of the first part; dismantling ancillary facilities of the second part, grouting the bottom of a side wall of the second part, chiseling away an original inverted arch structure of the second part, pouring a new inverted arch structure of the second part, and then paving a new road surface of the second part; and chiseling away the original inverted arch structure of the first part after the road surface is widened, pouring the new inverted arch structure of the first part, and then laying the new road surface of the first part. By means of the method, the influence on traffic is reduced.
本发明涉及一种公路隧道仰拱更换施工方法，包括以下步骤：根据隧道内公路的中心线将隧道分为第一部分和第二部分；拆除第一部分的附属设施，并在第一部分边墙底部注浆，在边墙底部铺设临时路面，对第一部分的路面进行加宽；拆除第二部分的附属设施，并在第二部分边墙底部注浆，凿除第二部分原有仰拱结构，并浇注第二部分的新仰拱结构，然后铺设第二部分的新路面；凿除路面加宽后的第一部分的原有仰拱结构，并浇注第一部分的新仰拱结构，然后铺设第一部分的新路面，采用本发明的方法降低了对交通的影响。
