Structure and method for eliminating differential settlement of new roadbed and old roadbed
The invention relates to a structure and a method for eliminating differential settlement of new and old roadbeds, which are characterized in that under the condition of differential settlement of the new and old roadbeds in the roadbed construction process or after operation, the height difference value of the existing new and old roadbeds is read through an automatic measuring scale with scales of a photovoltaic system. The photovoltaic power generation technology is used for electrifying the wire to supply power to the grouting machine, the heating piece and the temperature and humidity integrated sensor, the heating piece conducts heat to the steel pipe after being heated, the steel pipe is heated to dry and evaporate soil moisture absorbed by the water absorption film, and surrounding soil is heated to expand. And a mixed material of cement paste and nanogel in a certain proportion is injected through the grouting pipe, so that the whole new roadbed is lifted. In addition, small-equal-interval geogrids connected with the old roadbed are laid in the new roadbed, so that the overall strength of a soil body of the new roadbed can be improved, the new roadbed is lifted, and the purpose of thoroughly eliminating differential settlement of the new roadbed and the old roadbed is achieved.
本发明涉及一种消除新老路基差异沉降的结构及方法,在路基施工过程或运营后新老路基发生差异沉降情况下,通过光伏系统自带的具有刻度的自动测量标尺读取现有新老路基的高度差值。利用光伏发电技术使导线通电,向注浆机、发热片及温湿度一体化传感器供电,发热片经加热后将热量传导给钢管,钢管受热将吸水膜吸收的土壤水分烘干蒸发,使周围土体受热膨胀。通过注浆管注射一定比例的水泥浆与纳米凝胶混合材料,使得新路基整体抬升。另外,新路基中铺设有与老路基相连接的小等间距土工格栅可提高新路基土体整体强度,实现新路基的抬升,达到彻底消除新老路基差异沉降的目的。
