Construction technology for preventing cement concrete pavement longitudinal joint edge gnawing
The invention provides a construction technology for preventing cement concrete pavement longitudinal joint edge gnawing, and relates to the field of road construction. The technology specifically comprises the following steps that when a cement concrete pavement is poured, after steel formworks on the two sides of a surface layer are fixed, oil is smeared on the upper half portions of the steel formworks, one half of a plastic film is attached to the steel formworks, the other half of the plastic film is laid on a lower bearing layer, then a tension rod is inserted to position the plastic film, a lateral blocking interface for concrete is formed, and concrete is poured. According to the technology, the plastic film is fixed through a tension bar, the working procedures are required in sequence, other technologies and working procedures of cement concrete pavement construction are not changed, the two working procedures of caulking by mixing cement mortar and removing caulking solidification materials after formwork removal are omitted, and more importantly, after traffic is open, the edge gnawing phenomenon of longitudinal joints in the middle of a road cannot occur.
本发明提出了一种防止水泥混凝土路面纵缝啃边的施工工艺，涉及道路施工的领域。工艺具体包括如下步骤：在水泥混凝土路面浇筑时，面层两侧钢模板固定后，钢模板上半部分抹油，将塑料膜一半贴在钢模板上，另一半铺在下承层上，再插入拉力杆定位塑料膜，形成一个对混凝土的侧向阻隔界面，浇筑混凝土。本工艺除了利用拉力杆固定塑料膜，工序上有先后要求，水泥混凝土路面施工的其他工艺和工序不变，节省了拌水泥砂浆堵缝和拆模后清除堵缝凝固料两个工序全部外，更主要的是通车后，路中间的纵缝不会发生啃边现象。
