Technical Field
The invention relates to the technical field of highway engineering, in particular to a safety protection device for a landslide-prone foundation pit of highway engineering.
Background
The foundation pit is a soil pit excavated at the design position of the foundation according to the elevation of the foundation and the plane size of the foundation. Before excavation, an excavation scheme is determined according to geological and hydrological data and the conditions of buildings nearby the site, and waterproof drainage work is performed. The person who is not excavated can use the method of putting the side slope to stabilize the earth slope, and the size of the slope is determined according to the relevant construction regulations. When a deeper foundation pit and a building adjacent to the deeper foundation pit are excavated, a foundation pit wall supporting method, a concrete-sprayed wall protecting method and a large foundation pit are used, and even an underground continuous wall and a columnar column type bored pile are used for interlocking, so that an outer soil layer is prevented from collapsing; for those who have no influence on nearby buildings, the underground water level can be reduced by a well point method, and slope releasing open cut is adopted; in cold regions, natural cold freezing method can be adopted for excavation and the like.
At present, a highway engineering foundation pit supporting mode basically adopts anchoring support, temporary retaining wall support or retaining pouring row piles or underground continuous wall support, but the existing protective device does not have the adjusting function, the excavated foundation pit support is usually directly scrapped after highway engineering is finished, and when the highway engineering is operated in a region with large rainfall, the excavated foundation pit is easy to slide due to the erosion of rainwater, and the protective device cannot effectively support a base. In view of this, we propose a highway engineering easy landslide foundation ditch safety device.
