Abstract
The invention discloses a supporting construction technology for a deep foundation pit nearby a road on the complicated geological conditions. The technology comprises the following steps of first, carrying out foundation pit excavation to the lithosphere, and carrying out slope setting construction to form a first foundation pit; second, driving first column piles on the edge of the pit bottom ofthe first foundation pit to form first batter post supporting; third, carrying out lithosphere excavation at the pit bottom of the first foundation pit to form a second foundation pit, carrying out slope setting construction, and then carrying out anchor rod supporting; and fourth, driving second column piles on the edge of the pit bottom of the second foundation pit to form second batter post supporting. According to the supporting construction technology for the deep foundation pit nearby the road on the complicated geological conditions, supporting on the deep foundation pit is implementedin the manner of arranging anchor rod supporting between batter post supporting, the problems that supporting for a deep foundation pit nearby the road on complicated geological conditions is difficult to carry out, high in construction cost, prone to having potential safety hazard, and the like are solved, supporting construction of the deep foundation pit nearby the road on the complicated geological conditions can be implemented, and the successful practice experience is provided for the field of supporting construction.
