Retaining pile combines anti structure of floating in subway station of anti floating block

The utility model relates to a retaining pile combines anti structure of floating in subway station of anti floating block. Construction stage adoption often in subway station is hugged closely the station roof and is set up anti the floating of method that anti fuliang bears down on one alone, because there is the problem that the interface is hard to manage, the steel bar connection degree of difficulty is big in the interior pre -buried muscle in earlier stage of retaining pile, later stage bar planting process is complicated moreover. The utility model discloses make guan liang in the retaining pile pile bolck to inboard protrusion, set up preformed reinforcement bar and the reinforcing bar ware of plugging into in the projecting part, guanliang's projecting part throws away downwards and reserves section, concrete -filled forms anti floating block between the top surface of station roof both sides tip and the hat roof beam projecting part to pour preformed reinforcement bar in an organic whole. The utility model discloses make guan liang and the anti floating block of concrete form a whole, utilize anti floating block to reach the anti purpose of floating jointly to the downward pressure of station top production, envelope's dead weight and side friction resistance, have low cost, simple process, the quality is easily controlled and the convenient advantage of site operation.
