Structure base slab top surface；
4) cladding processing is carried out in the overlap joint layer surface with coiled material, forms the first coiled material layer；
5) asphalt water-proof coiled material is buried in bottom at split joint, forms the second coiled material layer, first interim solid after the completion of construction
It is scheduled at past harden structure；
6) after the completion of the filling such as soil layer of old structure bottom for excavating step 1), the construction again of new bed course is carried out, after
Temporarily fixed second coiled material layer of expansion, and bury a foam spacer rod in the second coiled material layer bottom；
7) expansion polyphenyl plate is laid in the second coiled material layer upper face, expansion polyphenyl plate thickness should combine slit width and nine
The THICKNESS CALCULATION of laminate, expansion polyphenyl plate point are bonded on the waterproof layer of old structure；
8) nine laminates are laid in the expansion polyphenyl plate surface, the nine laminates point is bonded on the expansion polyphenyl plate；
9) after the second coiled material layer expansion, overlap joint processing, new bed course position are carried out with the new waterproof layer at new bed course position
New waterproof layer on turn to the tops of expansion polyphenyl plate and nine laminates；
10) casting concrete, concrete floor is formed, after concrete floor reaches intensity requirement, precompressed is layered on swollen
It is rear to reject expansion polyphenyl plate and nine laminates in new waterproof layer paving to new construction side wall at the top of swollen styrofoam and nine laminates；
11) the corresponding encapsulant of pointing, pointing layer is formed.
Further, step 1) the hole side is inclined-plane
Further, the width in the step 1) hole be 450-550mm, depth 450-550mm.
Further, the lap width of the step 3) bonding layer and old structure bottom waterproof layer is not less than 500mm, continues
To old structure base slab top surface at least 300mm.
Further, step 5) the second coiled material layer length is not less than 2m.
Further, step 5) second coiled material layer uses RWB-801 polymer modified bituminous waterproof sheet materials.
Further, nine laminate bottoms are supported using pea gravel concreten described in step 8), on nine laminate
Portion can use the waterproof layer at newly-built bed course position to turn over bag processing.
Further, the pointing layer described in step 10) includes uncured rubber asphalt, building asphalt successively by inward at both ends
Glue, water expandable waterstop.
Further, side wall additional waterproof course and waterproof layer are set up after step 10), pours top concrete, then another increasing
If film and waterproof coiled material extra play.
The beneficial effects of the present invention are effectively solve the waterproof guard difficult point at the movement joint position brought in enlarging construction
And leakage problems.
