Foundation pit support engineering has many intimate links with each other, like retaining wall, supporting structure, waterproof measure, precipitation process and soil excavation engineering, etc. If one link is invalid, the whole engineering will be failure.
Before construction, geological exploration and underground pipes should be firstly known. Then construction scheme should be drawn up according to geological conditions and foundation depth. Only it is consistent with condition of construction site, can construction scheme truly guide actual construction.
Content of construction scheme should include following factors: design of supporting structure, choice of machine types, excavation order and depth, slope location and load, entrance-exit road, drainage measure and monitoring demand, etc.
Based on influence of construction condition, geological condition, ground load condition and other factors, supporting structure of foundation pit support engineering should carry out deformation monitoring and have monitoring record correspondingly.
Monitoring of foundation pit support engineering is to monitor the whole construction process of self drilling bolt(pernos autoperforantes
), referring to surrounding rock’s character, supporting structure deflection and variation of surrounding environment, which refers to the whole construction process of self drilling bolt, that’s to say, from excavation to operation.
