Claim 6:
7. The construction method for the road structure reconstructed from large-scale independent underground garage according to claim 4, wherein the step S500 comprises the following sub-steps:
S501: shattering a wall, comprising: shattering, according to requirements, an exterior wall (36) of the reconstructed partially underground garage (35) opposite to the road, and preserving the side wall (19) of the original underground garage and the partially preserved garage (20),
S502: providing the partition wall (11) and the girder (24), comprising: preserving frame columns (13) between a reconstructed part and a preserved part on a side of the preserved part, providing bonded rebars (18) at the frame columns (13) of the reconstructed partially underground garage (35), binding the rebars along the direction of the road, and pouring concrete to form the partition wall (11), and pouring the girder (24) on the upper side of the partition wall (11) in the transverse direction,
S503: reconstruction for the roof plate (4), comprising: roughening both the upper and lower sides of the roof plate (4) of the reconstructed partially underground garage (35), binding the upper and lower sides of the roof plate (4) with rebar meshes, laying formworks on the upper and lower sides of the roof plate (4), and pouring the concrete to form the upper plate (23) and the lower plate (29),
S504: reconstruction for an upper layer of the road, comprising: laying the concrete layer (22), the slag (7), and the road structure layer (8) on the newly poured upper plate (23) from bottom to top in sequence to form the upper layer of the road,
S505: burying for an upper drainage pipe, comprising: providing the central drainage pipeline (9) inside the concrete layer (22), burying the longitudinal drainage pipelines (10) buried on both sides of the concrete layer (22), and providing the transversal drainage pipeline (14) between the central drainage pipeline (9) and the longitudinal drainage pipelines (10),
S506: reconstruction for a lower layer of the road, comprising: laying the road structure subcrust (28), the concrete base (27), the coarse asphalt lower surface course (26), and the fine asphalt surface course (25) on the floor plate (1) of the underground garage in sequence,
S507: burying for a lower drainage pipe, comprising: laying the lower layer drainage system (40) inside the concrete base (27), wherein the lower layer drainage system (40) comprises the lower layer horizontal drainage pipe (41), the lower layer longitudinal drainage pipe (38), and the inspection well (39), laying the lower layer horizontal drainage pipe (41) perpendicular to the direction of the road, laying the lower layer longitudinal drainage pipe (38) along both sides of the direction of the road, and providing the inspection well (39) at the connection part of the lower layer horizontal drainage pipe (41) and the lower layer longitudinal drainage pipe (38).
