Grouting construction method for highway reconstruction and extension bridgehead transition slab
The invention discloses a highway reconstruction and extension bridgehead transition slab grouting construction method. The method comprises the following steps that transition slabs are placed side by side at a roadbed of a pavement needing to be extended; grouting holes are formed in the transition slabs and the roadbed; grouting pipes are inserted into the grouting holes, and hole sealing treatment is conducted; and slurry is injected into the grouting holes, grouting is stopped and grouting openings are closed after injection is completed, and the grouting pipes above the transition slab face are removed after the slurry is solidified. The highway reconstruction and extension bridgehead transition slab grouting construction method has the advantages that the problem of pavement subsidence diseases caused by large differential settlement due to large difference of roadbed consolidation degrees in new and old roadbed splicing at the bridge transition slab under the tense construction period of highway reconstruction and extension is effectively solved; the construction is convenient, safe and reliable, materials are simple, the manufacturing is easy, the cost is low, and the method can be used as an effective reference for similar construction.
本发明公开了一种高速公路改扩建桥头搭板注浆施工方法，包括以下步骤：在需扩建路面的路基处并排放置搭板；在搭板及路基上设置注浆孔；向注浆孔内插入注浆管，并进行封孔处理；向注浆孔内注入浆料，待注入完毕，停止注浆并封闭注浆口，待浆料凝固去除搭板面以上的注浆管。本发明的有益效果为：本发明所述的高速公路改扩建桥头搭板注浆施工方法有效解决了高速公路改扩建紧张工期下桥梁搭板处新旧路基拼接因路基固结程度差异较大而产生较大差异沉降造成路面沉陷病害的问题，不但施工方便、安全可靠，而且材料简单，易于制作，成本低廉，可作为相似或同类施工的有效借鉴。
