Design and construction method of pavement anti-crack reinforcing mesh for road intersection
The invention discloses a pavement anti-crack reinforcing mesh design and construction method for a road intersection, and belongs to the technical field of urban traffic, and the method comprises the following steps: S1, selecting a reinforcing mesh arrangement range and reinforcing mesh distribution parameters, and determining a reinforcing mesh arrangement range according to a traffic grade; according to the road intersection corner angle, the included angle alpha between transverse steel bars and longitudinal steel bars of the arranged steel bar mesh is determined; s2, a reinforcing mesh is arranged, specifically, the reinforcing mesh is installed in the mode that a support is erected in advance, transverse reinforcing steel bars are arranged on the straight section of the entrance and exit intersection, and longitudinal reinforcing steel bars are arranged on the transverse reinforcing steel bars; and S03, end treatment is carried out, inclined expansion joints are arranged at the ends of the inlet and outlet intersections, longitudinal steel bars at the expansion joints extend outwards to cross the expansion joints to serve as dowel bars, and finally concrete is integrally poured. The problems of slab staggering, slab breaking, mud pumping and the like which are easily generated on the cement pavement at the intersection are solved. The method has the advantages that the safety is improved, and the driving comfort is improved.
本发明公开了一种用于道路交口的路面抗裂钢筋网设计和施工方法，属于城市交通技术领域，包括如下步骤：S1.选定布筋范围和配筋参数，根据交通等级确定布设钢筋网的范围；根据道路交叉口转角角度，确定所布设钢筋网横向钢筋和纵向钢筋夹角α；S2.钢筋网的布设，采用预先用支架架设的方式安装钢筋网，在进出交叉口的直行段布设横向钢筋，在横向钢筋上布设纵向钢筋；S03.端部处理，在进出交叉口的端部设置斜向胀缝，胀缝处纵向钢筋向外延伸越过胀缝作为传力杆，最后整体浇筑混凝土。解决了针对交叉口处水泥路面易产生的错台、断板、唧泥等病害问题。具有提高安全性、改善行车舒适性的优势。
