The utility model discloses a drainage sheet and geotechnological cloth filter layer gluing form compound sheet, and peel strength is high, has the effect of preventing collapsing, dispersing the atress, makes the drainage space more spacious.
Description
Technical Field
The utility model belongs to the technical field of the drainage, concretely relates to row sheet is prevented to polymer.
Background
The China building waterproofing Association has published reports that the permeability of roofs of domestic main urban buildings is as high as 95.33%, 57.51% of underground buildings have leakage in different degrees, and nearly four-member households suffer from house leakage. The infiltration becomes a common disease of buildings in China, and the coverage is extremely wide.
The building water-proof is a system project, the construction of three-component materials is divided into seven parts, and in addition, the upstream and downstream communication cooperation such as design, maintenance and the like is needed. The quality is good and irregular, the design has defects, auxiliary material machines are absent, standard procedures are absent, organization discipline is absent, the quality of workers is low, the responsibility is low, engineering management is weak, the construction process is not properly supervised, careless mistakes are found in acceptance check, guidance cannot be provided, service matching is incomplete, and a quality assurance system is absent.
The drainage-preventing sheet is a key building waterproof component and plays an important role in waterproof performance. The drainage-preventing sheet in the prior art is mostly a laminated result, and the drainage space is small. In order to achieve the root-blocking effect, the growth of the root system is inhibited by increasing chemical root-blocking components or the damage of the root system is resisted by using a metal material, the effect is poor, and the cost of the formed material is high.
Disclosure of Invention
The purpose of the invention is as follows: the utility model aims to provide a row sheet is prevented to polymer to prior art not enough, with low costs, the drainage space is more spacious.
The technical scheme is as follows: the polymer anti-drainage sheet of the utility model comprises a self-adhesive layer, a drainage sheet and a filter layer from bottom to top in sequence; the drainage sheet comprises a support plate and support columns uniformly distributed on the support plate, the support columns are of hollow structures, one ends of the support columns, which are connected with the support plate, are open, and the other ends of the support columns, which are connected with the filter layer, are of closed structures.
Further, the supporting plate and the supporting column are of an integrally formed structure.
Further, the diameter of the opening end of the supporting column is contracted towards the diameter of the closing end.
Further, the filter layer is geotextile.
Furthermore, the drainage sheet material is made of high-density polyethylene.
Has the advantages that: compared with the prior art, the utility model has the advantages of: the utility model provides a high polymer anti-drainage sheet, which adopts the abnormal drainage sheet made of high density polyethylene material and has waterproof function, has root puncture resistance physical root resistance function, and can replace the traditional root puncture resistance coiled material, thereby directly reducing the construction cost; the drainage sheet and the geotextile filter layer are bonded to form the composite sheet, the peeling strength is high, the collapse prevention effect is achieved, the stress is dispersed, and the drainage space is wider.

Detailed Description
The technical solution of the present invention is described in detail below with reference to the accompanying drawings, but the scope of the present invention is not limited to the embodiments.
The polymeric anti-drainage sheet shown in fig. 1 to 3 sequentially comprises a self-adhesive layer 4, a drainage sheet and a filter layer 3 from bottom to top; the drainage sheet includes backup pad 1 and is the support column 2 of evenly arranging in backup pad 1, and backup pad 1 and support column 3 are integrated into one piece structure, and support column 3 is hollow structure, and the one end that support column 2 links to each other with backup pad 1 is the opening form, is the closed structure with the one end that filter layer 3 links to each other, and the diameter of support column 2 open end is the shrink form towards the diameter of closed end.
The drainage sheet material is made of high-density polyethylene. The self-adhesive layer 4 is made of creep asphalt waterproof coating, and the filter layer 3 is made of geotextile.
The special-shaped drainage sheet material with the waterproof function, which is made of the high-density polyethylene material, has the root puncture resistance physical root resistance function, and can replace the traditional root puncture resistance coiled material, thereby directly reducing the construction cost; the drainage sheet and the geotextile filter layer are bonded to form the composite sheet, the peeling strength is high, the collapse prevention effect is achieved, the stress is dispersed, and the drainage space is wider.
Performance parameters:
tensile strength (unit N/cm): longitudinal 96.4, transverse 111.9;
tensile elongation (%): longitudinal 119, transverse 158;
compressive strength (unit: kPa): 539;
drainage cutArea (unit: cm)2)：71；
Hot air aging, tensile strength retention (%): longitudinal direction 108, transverse direction 96; tensile elongation retention (%): longitudinal direction: 73. transverse: 107;
alkali resistance, tensile strength retention (%): longitudinal 106, transverse 92; tensile elongation retention (%): longitudinal direction: 83. transverse: 100.
as mentioned above, although the present invention has been shown and described with reference to certain preferred embodiments, it should not be construed as limiting the invention itself. Various changes in form and detail may be made therein without departing from the spirit and scope of the invention as defined by the appended claims.
