Slipform construction method of road edge stone

1 前言

1 Preface

随着我国高等级公路的飞速发展，全面推行机械化施工，是大势所趋，这对于提高施工质量，加快施工进度有着重要作用。预制法路缘石施工主要是把预制好的路缘石砌在路肩预挖的沟槽中。施工进度慢、工序多、占用场地大，路缘石的整体强度差、线条不顺畅。滑模施工法是采用路缘石滑模机在施工现场将新拌路缘石材料连续现浇．并密实成型．每天可铺筑1500m左右。滑模法铺筑路缘石速度快、所需人工少、不需要预制场地，铺筑的路缘石整体结构强度高、线型顺畅美观，倍受施工单位和业主的青睐。

With the rapid development of high grade highway in our country, it is the general trend to carry out mechanized construction in an all-round way, which plays an important role in improving the quality of construction and speeding up the construction progress. Prefabricated road curb construction is mainly made of precast curb stone in the trench excavated on the shoulder. The construction progress is slow, the process is much, the occupying site is large, the overall strength of the curb is poor, and the lines are not smooth. The slipform construction method is to use the slippery stone slipform machine to continuously pour the new curb stone material at the construction site, and to form it densely. It can lay 1500m every day. The sliding mode method has the advantages of fast speed, less manpower and no need for precast sites. The overall structure of the paved road stone is of high strength and smooth and beautiful line type. It is favored by the construction units and the owners.
