Description

Subway station lid digs roof construction structures Technical Field The invention belongs to the technical field related to subway construction, and particularly discloses a cover-digging roof construction structure of a subway station. Background In top-down construction method roof construction, steel beams (or steel reinforced concrete beams) are used as main bearing frameworks, more spandrel girders are erected among the symmetrically arranged steel beams, concrete is poured outside to form a composite structure, a later-stage roof (namely a pavement restoration layer/a temporary pavement layer) is formed by concrete sealing, and the construction of the roof is a core link of the whole engineering, and the quality of the roof directly influences the subsequent traffic restoration, foundation pit safety and permanent structural performance. However, in the triangular area where the steel girder web plate, the flange and the concrete are in juncture, the steel girder flange forms a vertical baffle, the structure of the vertical baffle can prevent the concrete from sinking under the dead weight, boundary layers can be generated on two sides of the vertical baffle, aggregate accumulation is not uniform enough, and the slurry cannot be filled into the root of the steel girder. The prior art is that small-size vibrating rod is inserted to the manual work for the club head is in deep into girder steel and bearing beam's interval, carries out the disturbance to the concrete, and the action dynamics of manual work is uneven, and the degree of depth is uncontrollable, in the construction, can't quantitatively judge the lost state of local concrete, relies on later detection, causes the roof to bring a lot of potential safety hazards as interim pavement layer.
