Abstract
The invention belongs to the technical field of landslide treatment, and particularly relates to a sliding bedding sandy mudstone slope treatment technology. The sliding bedding sandy mudstone slope treatment technology comprises the steps of exploration and preparation, fore shaft construction, pile body construction, excavation and slope releasing and the like. Compared with a traditional mode that excavation and slope releasing are conducted firstly and then anti-slide pile construction is conducted, the actual construction fore shaft elevation is made to be higher than the designed fore shaft elevation by manually filling a foundation, and after the condition that the slope stability is met, or under the condition that the actual construction fore shaft elevation is higher than the designed fore shaft elevation, anti-slide piles are constructed firstly, and then reverse construction method manual excavation is conducted. According to the sliding bedding sandy mudstone slope treatment technology, anti-slide pile construction can be directly conducted on a sliding slope, reverse construction method construction is conducted after the fore shaft elevation is increased and filling is conducted again, the hidden danger of slope collapse during manual anti-slide pile hole excavation construction and the landslide hidden danger of a whole slope top mountain are eliminated, the construction safety is ensured, the construction progress is ensured, and the construction cost is reduced.
Description
technical field [0001] The invention belongs to the technical field of landslide treatment, and in particular relates to the treatment technology for sliding bedding sandy mudstone slopes. Background technique [0002] Landslide is the process and phenomenon in which the local stability of the slope is destroyed. Under the action of gravity, the rock mass or other debris slides downward along one or more fractured sliding surfaces as a whole, which brings hidden dangers to road safety. There are many factors that induce landslides. The geological structure and physical and mechanical properties of slope rock and soil are the internal factors that determine its stability. Rainfall, groundwater level changes, and human engineering activities are external factors that affect slope stability. The formation of landslides The process is often the result of the interaction of internal and external factors. [0003] Non-patent literature: [11] Jiang Weixue, Xue Minchen. Mechanism A...
