RIBBED COLUMN DISTRIBUTED TURNOUT FOUNDATION STRUCTURE FOR LOW-SET MID-TO-LOW SPEED MAGNETIC LEVITATION LINE

摘要

A ribbed column distributed turnout foundation structure for a low-set mid-to-slow speed magnetic levitation line comprising turnout zone foundation treatment reinforced concrete raft slabs (2), turnout beam strip-shaped reinforced concrete ribbed column foundations (1), cast-in-drilled-hole reinforced concrete piles (3), steel plates and embedded bolts (4). The turnout zone foundation treatment reinforced concrete raft slabs (2) are arranged horizontally, and the multiple cast-in-drilled-hole reinforced concrete piles (3) are arranged at the bottom surfaces of the turnout zone foundation treatment reinforced concrete raft slabs (2); the cast-in-drilled-hole reinforced concrete piles (3) penetrate a soft stratum (5) to extend into a bearing stratum (6), so as to decrease the deformation of turnout beams in the rotation process. The present invention ensures that the turnout beams are not deformed substantially in the rotation process due to inadequate foundation stiffness, and meets the requirements for foundation strength and stability of the turnout beams.
