Reinforcing structure for road shallow-buried box culvert and construction method
The invention relates to areinforcing structure for a road shallow-buried box culvert and a construction method, and relates to urban road and bridge culvert engineering, a steel plate is adopted to reinforce an existing box culvert, anchor bolts are adopted to fix the box culvert, the steel plate limits the movement and deformation of the steel plate under the constraint of anchor bolt fixation, and a gap between the steel plate and the existing box culvert is grouted to form sound contact, the contact area is increased, the acting force of vehicle loads on an existing box culvert is dispersed, the internal force borne by the existing box culvert is reduced, the butt straps are additionally arranged on the two sides of the existing box culvert to form an integral structure jointly stressed, and the structure requirement for additionally paving a road surface on the shallow-buried box culvert is met by adopting a thin structure layer. The structure overcomes the defects that an existing box culvert is limited by road elevation, the burial depth is small, the thickness of an upper structure is small, and the structural strength of the box culvert cannot meet the load of an extended road, the existing box culvert is used for reinforcement, the manufacturing cost is saved, the construction period is shortened, and the influence on current road traffic is small.
本发明涉及一种用于道路浅埋箱涵加固补强结构及施工方法，涉及城市道路及桥涵工程，采用钢板对现有箱涵加固并采用锚栓固定，钢板在锚栓固定的约束下，限制钢板的移动和变形，钢板与现有箱涵之间的缝隙注浆，形成良好的接触，增加了接触面积，使得车辆荷载对现有箱涵的作用力分散，现有箱涵所受的内力减小，现有箱涵两侧增设搭板，形成一个共同受力的整体结构构造，采用较薄的结构层满足浅埋箱涵加铺路面的构造要求。该结构克服了现有箱涵受道路标高限制，埋深较浅上部构造厚度小，箱涵结构强度不满足扩建道路荷载的缺陷，利用现有箱涵进行加固，节约造价，减少施工周期，对现状道路交通影响小。
