Multi-pile-type conversion disposal structure under limit racing track complex geology and construction method thereof

Abstract

The invention discloses a multi-pile type conversion disposal structure under limit racing track complex geology and a construction method thereof. The multi-pile type conversion disposal structure under limit racing track complex geology comprises a single pile area, a mixed pile area, a CFG pile area and a local treatment pile area which are arranged on a soil body below a racing track, a mucky soil layer and an underground water layer are arranged below the racing track, and a river or a water body is further arranged on one side of the racing track. According to the method, the soil bodies below the racing track are treated in different areas, so that the stress requirements of the soil bodies of different racing sections can be met in a targeted mode, and different geologies can be treated in a targeted mode; through combined application of PHC piles and stirring piles, the requirement for bearing capacity is met, and it can be guaranteed that settlement deformation of the soil body meets the requirement; through the arrangement of pile caps, the stress balance of the PHC piles and the CFG piles can be improved, and the bearing capacity can be improved through treatment of the pile caps; and through classification of pile body retreatment under different construction progresses in the construction process, treatment schemes can be effectively distinguished, the construction quality is guaranteed, construction is convenient and fast, and working hours are saved.

Description

technical field [0001] The invention belongs to the technical field of building construction, and in particular relates to a multi-pile conversion and disposal structure and a construction method thereof under complex geology of an extreme race track. Background technique [0002] During the construction of the track, the track itself and the underlying soil need to bear short-term strong loads, especially in the extreme section of the track and the extreme corner track, this force will greatly affect the track The construction design and the treatment of the lower soil. In addition, when the track encounters unfavorable geology and soil rich in groundwater, the treatment of the soil below the track is more complicated. At present, there are few targeted measures for underground treatment of advanced extreme tracks in my country, especially in the construction process, there is no corresponding design on how to carry out construction in sites with poor geology, groundwater ...

AI Technical Summary
