Disease treatment construction process for old cement pavement and drilling device
The invention relates to the technical field of road repair engineering, in particular to an old cement pavement disease treatment construction process and a drilling device.The old cement pavement disease treatment construction process comprises the steps that S1, a transport vehicle is driven to a tested plate body of a pavement, a Beckmann deflectometer is placed on a non-tested plate body adjacent to the tested plate body, and a measuring head of the Beckmann deflectometer makes contact with the tested plate body; s2, enabling the transport vehicle to run, and measuring a rebound deflection value of the tested plate body through a Beckmann deflectometer; s3, making a punching mark on the tested plate body; s4, a drilling device is used for drilling the punching mark to form a grouting hole, and concrete slurry is poured into the grouting hole; s5, grouting and deflection re-measurement are carried out on the tested plate body, 1-2 grouting holes are supplemented near the hole positions of the grouting holes, and secondary grouting is carried out; s6, the grouting holes are sealed; and S7, finish milling is conducted on the pavement, and then cover face construction is conducted. According to the invention, the repairing effect of the void pavement can be optimized.
本申请涉及道路修复工程技术领域，尤其是涉及一种旧水泥路面病害处治施工工艺及钻孔装置，包括：S1、将运输车行驶到路面的受测板体上，将贝克曼弯沉仪放置在与受测板体相邻的非受测板体上，使贝克曼弯沉仪的测头与受测板体相接触；S2、令运输车行驶，通过贝克曼弯沉仪测量出受测板体的回弹弯沉值；S3、在受测板体上作打孔标记；S4、使用钻孔装置对打孔标记处进行钻孔，形成灌浆孔，向灌浆孔内灌注砼浆；S5、对受测板体进行压浆与弯沉复测，在灌浆孔的孔位附近补1‑2个灌浆孔，进行第二次压浆；S6、对灌浆孔进行封孔；S7、对路面进行精铣刨，然后进行罩面施工。本申请可优化脱空路面的修补效果。
