the asphalt waterproof coiled material is a layer of 1.5 mm-later self-adhesive padding-free high polymer modified asphalt waterproof coiled material on the surface of a waterproof coating, and an additional layer with the width of 250mm is additionally arranged at a corner; the asphalt coiled material waterproof layer is externally provided with a heat insulation material which is the same as the waterproof material of the outer wall, and the layered backfilling is carried out after the heat insulation layer is manufactured.
The protective structure of the basement outer wall post-cast strip can be further realized by adopting the following technical measures.
The protective structure of the basement exterior wall post-cast strip is characterized in that the masonry strength of the brick wall is M10.
According to the protective structure of the basement outer wall post-cast strip, the thickness of the cement waterproof mortar is more than or equal to 10 mm.
After the technical scheme is adopted, the protective structure of the basement outer wall post-cast strip has the following advantages:
1. the structure layer is scientific and reasonable in arrangement, and the construction operation is simple, safe and efficient;
2. the stress is more reasonable, and the waterproof performance is better;
3. the common quality common fault and potential safety hazard easily generated by common building envelope construction technology are eliminated, and the social and economic benefits are remarkable.

Detailed Description
The present invention will be further described with reference to the following examples and the accompanying drawings.
Example 1
According to the protective structure of the basement outer wall post-cast strip, the staggered transverse reinforcing steel bars and longitudinal reinforcing steel bars are exposed at the basement post-cast strip, the steel plate waterstop structures are embedded at the positions 300mm away from the two edges of the basement post-cast strip, the steel plate waterstop structures are cast with the cast-in-place part of the side wall of the basement, the two ends of the lime-sand brick building enclosure are close to the steel plate waterstop structures, so that the basement post-cast strip is surrounded by the brick building enclosure 8 through the post-cast strip wood plywood formwork 9, and the protective structure of the basement outer wall post-cast strip comprises a brick wall 1, a waterproof layer 2 and asphalt waterproof coiled.
Referring to fig. 1 and 2, fig. 1 is a schematic view of a protective structure of a post-cast strip of an exterior wall of a basement according to an embodiment of the invention, and fig. 2 is a cross-sectional view of a-a in fig. 1. As shown in the figure, the edges of two sides of the position reserved on the post-cast strip on the outer surface of the outer wall surface of the side wall of the basement are reference sidelines, the deviation of the edges to the direction of the solid wall surface of the cast-in-place part of the side wall of the basement is 300mm, a mortar brick wall with the thickness of 240mm and the strength of the brick wall of M10 is built, the building angle of the brick wall is 135 degrees, a layer of cement waterproof mortar with the thickness of 10mm is brushed on the outer wall surface of the mortar brick wall, the surface is compacted and leveled, the surface of the waterproof mortar is brushed with a layer of cement base 3 (for enhancing the waterproof performance of a protection structure), and the surface of the cement base is; waterproof paint is fully brushed to the protection architecture top surface, and waterproof paint surface is done one deck 1.5mm back self-adhesion not child high polymer modified asphalt waterproofing membrane, and the wide additional layer of 250mm is increased to the corner, and outside the coiled material waterproof layer, use the insulation material the same with outer wall waterproof material, carry out layering backfill 7 after heat preservation 6 has been done. After the protective structure is formed, the lateral pressure of backfill can be resisted through the self strength and the structural integrity, so that the periphery of the side wall shear wall can be backfilled as early as possible, and conditions are created for subsequent structural construction. Meanwhile, multiple waterproof measures can effectively prevent water in the foundation pit from leaking or flowing into the reserved cavity of the post-cast strip to be corroded and pollute the reinforcing steel bars, and the leakage risk of the post-cast strip of the side wall of the basement is effectively prevented and treated.
