高聚物注浆能够有效的治理水泥面板脱空造成承载力不足的情况,避免采取凿除水泥混凝土面板的高成本施工,造成无端的浪费,因此在高速公路水泥混凝土路面加固工程中可以采用高聚物注浆提高路面的承载力。本文将结合张承高速公路大华岭隧道水泥混凝土路面病害治理的施工实例,简要探讨高聚物注浆的具体施工过程,希望能对类似工程起到借鉴作用。
The polymer grouting can effectively control the lack of bearing capacity caused by the emptying of the cement panel and avoid the high cost construction of removing and removing the cement concrete slab, resulting in an unwarranted waste. Therefore, high cement concrete pavement reinforcement can be used high Polymer grouting to improve the bearing capacity of pavement. Based on the construction examples of cement concrete pavement disease treatment of Dahua Ridge Tunnel in Zhangcheng Expressway, this paper briefly discusses the concrete construction process of polymer grouting, and hopes to be able to draw lessons from similar projects.
