Description
Technical Field
The invention belongs to the technical field of structural waterproofing, and particularly relates to a construction method for pre-paving a waterproof coiled material overlap edge on a bottom plate and a bottom plate side mold supporting structure.
Background
Underground works receive the infiltration of groundwater constantly because bury deeply underground, if waterproof problem handles not well, lead to groundwater seepage to inside the building or the building is internal, will bring a series of problems: influence the work and life of personnel; the corrosion speed of the building is accelerated, and the service life is shortened.
According to the national standard GB50108-2008, the totally-closed and partially-closed waterproof and drainage design is adopted for the single-built underground engineering, and the waterproof material is paved from the structural bottom plate cushion layer to the top plate base surface and forms a closed waterproof layer at the periphery. The lapping length of the coiled material racking is 150mm for the high polymer modified asphalt coiled material, and 100mm for the synthetic high polymer coiled material; when two webs are used, the web seams should be staggered and the upper web should overlap the lower web. The common method adopted by the lap joint parts of different waterproof materials of the existing underground engineering is to build a brick moulding bed or adopt a wood moulding plate.
The masonry brick forming die generally has the following defects: the construction period is long, and the engineering cost is relatively high; the uneven settlement of the bottom plate and the brick moulding bed causes the easy damage of the waterproof lap joint part and the water leakage and the like.
The existing construction method for building the wood formwork is to turn over the lap joint edge of the pre-laid waterproof coiled material and then fix the lap joint edge on the wood formwork when building the wood formwork, and then construct a bottom plate. The reserved lap joint part of the waterproof roll is easy to be polluted and cannot be lapped with a side wall waterproof material to form a closed waterproof layer; or the polluted parts need to be eradicated and cleaned, which causes the construction procedure to be complicated; particularly, when the temporary wood formwork is used in the construction period, because the formwork is detached earlier, the vertical face coiled material fixed on the wood formwork is easy to tear off and is polluted by the bottom plate and the later construction; or the side wall waterproof material is not constructed for a long time, the overlapping edge of the waterproof coiled material on the vertical surface of the bottom plate is easy to be polluted by later construction or the waterproof coiled material slides downwards under the self weight, so that the waterproof coiled material is polluted by the bottom plate or other construction procedures.
