Control method and device for bridge deck pavement reinforcing mesh top surface protection layer
The invention belongs to a control method and device for a bridge deck pavement reinforcement mesh top surface protection layer, and the method comprises the steps: adjusting the lower ends of all limiting marker posts on a reinforcement protection layer elevation trolley to be on the same horizontal straight line, and controlling the top surface of a reinforcement mesh to be on the same horizontal plane meeting the design elevation requirement; according to the method, the defect that the elevation of the reinforcing mesh is controlled on the basis of the top surface of the bridge plate and is easily influenced by the change of the prestress of the top surface of the bridge plate in a traditional method is overcome, and the top surface of the reinforcing mesh is controlled at the designed elevation by adopting the reinforcing protective layer elevation trolley and is not influenced by the change of the prestress of the top surface of the bridge plate; the thickness of the protective layer on the top of the bridge deck pavement reinforcing mesh can be effectively controlled, cracking, deformation and collapse of the bridge deck can be effectively prevented, and the service life of the bridge can be greatly prolonged.
本发明属于一种桥面铺装钢筋网片顶面保护层的控制方法及其装置，采用调整钢筋保护层标高台车上的各限位标杆下端在同一水平直线上，且将钢筋网片顶面控制在与设计高程要求的同一水平面上，本发明克服了传统的控制钢筋网片标高是以桥梁板顶面为基础且易受桥梁板顶面预应力变化的影响的方法，本发明采用钢筋保护层标高台车将钢筋网片顶面控制在设计高程上，不会受桥梁板顶面预应力变化的影响，本发明能有效控制桥面铺装钢筋网片顶部保护层厚度，能有效防止桥面龟裂、变形和坍塌，可大幅度延长桥梁的使用寿命。
