Construction method for protective excavation of multiple pier foundation pits in steep slope section
The invention relates to the field of geotechnical engineering, and particularly relates to a construction method for protective excavation of multiple pier foundation pits in a steep slope section. Asupporting and blocking protector is arranged on the backing side of the preset pier foundation pit position, the pier foundation pits are excavated, and the next pier foundation pits are constructedone by one. When the pier foundation pits are constructed on an unstable stratum on a landslide mass or a rock pile, the mode of excavating piers one by one and supporting in time is adopted, compared with pull trough excavation of the multiple pier foundation pits, the integrity of the slope toe of a landslide is reserved, the unstable slope has a relatively stable supporting foundation, the construction influence is small, and slope stability and pier foundation stability are facilitated.
本发明涉及土工工程领域，具体涉及一种陡坡地段多个桥墩基坑防护开挖的施工方法，在预设桥墩基坑位置的靠山侧设置支挡防护，开挖桥墩基坑，逐个施工下一个桥墩基坑。桥墩基坑在滑坡体或岩堆上不稳定地层上施工时，采用逐墩开挖、及时支护的方式，相比多个桥墩基坑拉槽开挖，保留了滑坡坡脚处的完整性，使不稳定坡体有相对稳定的支撑基础，且施工影响小，利于边坡稳定及桥墩基础稳定。
