High-density polymer grouting reinforcement method for roadbed at sinking position of bridge and culvert butt strap
The invention discloses a high-density polymer grouting reinforcement method for a roadbed at the sinking position of a bridge and culvert butt strap. The method comprises the following steps that S1, grouting holes are formed; S2, drilling is conducted, specifically, a hollow drill is used for drilling to penetrate through a cement panel and a pavement base layer; S3, grouting pipes are placed; S4, grouting is conducted, specifically, the grouting sequence is from outside to inside, a high-density polymer liquid material conducts grouting on the peripheral grouting holes firstly, then conducts grouting on the inner peripheral grouting holes and finally conducts grouting on the inner center grouting holes; S5, the grouting process is monitored; S6, the grouting holes are closed; and S7, the environment is cleaned. According to the high-density polymer grouting reinforcement method for the roadbed at the sinking position of the bridge and culvert butt strap, the pavement base layer is maintained and the roadbed is reinforced by injecting the double-component high-density polymer liquid material, the injected high-density polymer liquid rapidly generates a chemical reaction to form a solid, the solid rapidly expands with the same volume to fill gaps in a pavement structure, and controllable pressure is applied to surrounding media to compact the roadbed.
本发明公开了一种桥涵搭板下沉处路基高密度聚合物注浆加固方法，包括以下步骤：S1、布置注浆孔；S2、钻孔，使用空心钻进行钻孔穿透水泥面板以及路面基层；S3、放置注浆管；S4、注浆，注浆顺序由外到内，高密度聚合物液体材料首先对外围的注浆孔进行注浆，其次对内围的注浆孔进行注浆，最后对内部中心的注浆孔进行注浆；S5、注浆过程监测；S6、封闭注浆孔；S7、清扫环境。该桥涵搭板下沉处路基高密度聚合物注浆加固方法，通过注射双组分高密度聚合物液体材料来维修路面基层和加固路基，注射的高密度聚合物液体迅速发生化学反应形成固体，同体积迅速膨胀，填充路面结构中的脱空，并向周围介质施加可控的压力，压密路基。
