In addition to the embodiments described herein, those skilled in the art will be able to employ other technical solutions which are obvious based on the disclosure of the claims and the specification of the present application, and these technical solutions include technical solutions which make any obvious replacement or modification for the embodiments described herein.
The drawings in the present specification are schematic views to assist in explaining the concept of the present invention, and schematically show the shapes of the respective portions and the mutual relationships thereof. It should be noted that for the sake of clarity in showing the structures of the various components of the embodiments of the present invention, the drawings are not drawn to the same scale. Like reference numerals are used to denote like parts.
A schematic diagram of a novel waterproof construction for basement roof, as shown in fig. 1 to fig. 2. The novel waterproof structure for the basement roof comprises a polyurethane coating waterproof layer 20, a modified asphalt waterproof coiled material 30, a polyethylene film 60, a concrete protective layer 70 and a backfill layer 80, wherein the polyurethane coating waterproof layer 20, the modified asphalt waterproof coiled material 30, the polyethylene film 60, the concrete protective layer 70 and the backfill layer 80 are sequentially arranged on the upper part of the roof 10; the thickness of the polyurethane paint waterproof layer 20 is 2mm, the polyurethane paint waterproof layer 20 is coated on the top plate 10, and the height difference control deviation of the polyurethane paint waterproof layer 20 is controlled within 5%.
The utility model discloses in, novel waterproof construction adopts the mode that film waterproof and coiled material are waterproof to combine together. It can be understood that the thickness of the polyurethane paint waterproof layer 20 can also be 1.5mm or 3mm, the polyurethane paint waterproof layer 20 needs to be coated uniformly, and the height difference is controlled to be 2% -3% to ensure a good waterproof effect.
As another embodiment of the present invention, the coating waterproof layer can also be coated with a polymer cement-based waterproof coating material, as long as the uniformity of the coating material is ensured.
In order to effectively avoid the influence of green planting on the waterproof structure, the novel waterproof structure further comprises an anti-root system piercing layer 40 and a geotextile 50, as shown in fig. 2, the modified asphalt waterproof roll material 30 and the polyethylene film 60 are arranged between the geotextile 50 and the modified asphalt waterproof roll material 30, and the anti-root system piercing layer 40 is positioned on the upper side of the geotextile 50.
As an aspect of this embodiment, the root system puncture resistant layer 40 is a PVC waterproof board, and its thickness is 1.5mm, has the root system that effectively prevents the green plant at the top of the basement to the influence of waterproof construction for the root system meets root system puncture resistant layer 40 and changes the direction and can not destroy waterproof construction. In another aspect of this embodiment, the geotextile 50 is a nonwoven geotextile having a tensile strength of not less than 8 kN/m.
In the embodiment shown in FIG. 1, the polyethylene film 60 has a thickness of 1mm to 2 mm. The modified asphalt waterproof roll material 30 is an N-type self-adhesive modified asphalt waterproof roll material, and the thickness of the modified asphalt waterproof roll material 30 is 1.5mm or 2 mm.

The upper part of the concrete protection layer 70 is provided with a backfill layer 80, the backfill layer is plain soil, and layered backfill is adopted to ensure the construction quality.
In the prior art, the single-layer or double-layer coiled material is generally waterproof, and because the coiled material is waterproof, a gap exists between the coiled material and a concrete base layer, the lapping engineering quantity of the coiled material and the coiled material is large, the joint bonding difficulty is large, and the problem of loose joints is easy to occur. When water permeates into the waterproof layer from the untight joint, the water flows along the gap between the coiled material and the concrete base layer to form large-area accumulated water below the waterproof layer, so that the waterproof layer is not only failed integrally, but also a leakage point is difficult to find and the maintenance is difficult.
The utility model discloses a way sets up the one deck earlier on roof concrete layer and coats the waterproof layer, lays the coiled material waterproof layer on the waterproof layer of coating again, makes to coat waterproof and the waterproof combination of coiled material, and the joint play acts on. Because the coating waterproof layer and the concrete base layer can be tightly combined, no gap exists, and meanwhile, a seamless continuous waterproof coating layer can be formed, so that the defects that the seam of the waterproof layer of the coiled material is not tight and a water seepage channel is formed by the gap between the waterproof layer of the coiled material and the base layer are avoided. In addition, once the water seepage is found, a water seepage point can be found quickly, and the maintenance is convenient.
The present invention is not limited to the above embodiments, and any person can obtain other products in various forms without departing from the scope of the present invention, but any change in shape or structure is included in the technical solution that is the same as or similar to the present invention.
