Technical Field
The utility model belongs to the technical field of the building and specifically relates to a special waterproof substrate of suspension type tunnel is related to.
Background
For tunnel waterproofing, generally, the waterproof is realized by laying a high-molecular waterproof roll layer, the cracking of the cement mortar sealing layer on the surface of the waterproof roll layer is easy to occur under the condition of thermal expansion and cold contraction under the common conditions, and the expansion stress of the cement mortar sealing layer acts on the waterproof structure, so that the cracking of the waterproof structure is caused, and the later-stage local water leakage is easily caused.
SUMMERY OF THE UTILITY MODEL
The utility model discloses an it is not enough to overcome above-mentioned condition, aims at providing a special waterproof substrate of suspension type tunnel.
In order to realize the purpose of the utility model, the utility model adopts the following technical scheme:
a suspension type waterproof base material special for a tunnel comprises a mortar leveling layer which is uniformly paved on the surface of a concrete base layer, wherein the mortar leveling layer has the function of filling gaps; the surface of the mortar leveling layer is coated with an adhesive layer, and a waterproof coil layer is adhered and fixed on the surface of the adhesive layer; the surface of waterproof roll material layer is paved with a hoisting stainless steel net layer, the surface of the hoisting stainless steel net layer is provided with a geotechnical non-woven fabric layer, the surface of the geotechnical non-woven fabric layer is paved with a plastic film layer, the surface of the plastic film layer is coated with a cement mortar sealing layer, the surface of the waterproof roll material layer is paved with the hoisting stainless steel net layer, the waterproof roll material layer is mainly formed by compounding a high polymer roll material layer and a high polymer coating layer, and the high polymer coating layer is coated on the surface of the high polymer roll material layer.
As a further aspect of the present invention: the thickness of the waterproof roll material layer is 0.1-0.2 mm.
As a further aspect of the present invention: the high polymer coiled material layer is made of polyvinyl chloride polypropylene coiled materials.
As a further aspect of the present invention: the polymer coating layer is made of polyurethane.
As a further aspect of the present invention: the thickness of the geotechnical non-woven fabric layer is 2-3 mm.
The utility model has the advantages that: the utility model discloses a lay stainless steel mesh structure, the stress effect that the shrink of hoist and mount stainless steel network layer or expansion produced all transmits for the waterproofing membrane layer with faint form, and the destruction that produces the waterproofing membrane layer like this is littleer to holistic intensity has been improved, hoist and mount stainless steel network layer simultaneously and also play the hoist and mount installation that also can make things convenient for the later stage, wholly provide effectual attached support.
Additional aspects and advantages of the invention will be set forth in part in the description which follows and, in part, will be obvious from the description, or may be learned by practice of the invention.
Drawings
Fig. 1 is a schematic structural diagram of the present invention.
In the figure: 1. a concrete base layer; 2. leveling mortar; 3. an adhesive layer; 4. a waterproof roll layer; 5. hoisting a stainless steel net layer; 6. a geotechnical non-woven fabric layer; 7. a plastic film layer; 8. and (5) sealing the cement mortar layer.
Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.
Referring to fig. 1, in an embodiment of the present invention, a suspended waterproof substrate for a tunnel includes a mortar leveling layer 2 uniformly laid on a surface of a concrete base layer 1, wherein the mortar leveling layer 2 has a gap filling function; the surface of the mortar leveling layer 2 is coated with an adhesive layer 3, a waterproof roll layer 4 is adhered and fixed on the surface of the adhesive layer 3, and effective water proofing is realized by utilizing the waterproof roll layer 4; the surface of the waterproof roll material layer 4 is paved with a hoisting stainless steel mesh layer 5, the surface of the hoisting stainless steel mesh layer 5 is provided with a geotechnical non-woven fabric layer 6, the surface of the geotechnical non-woven fabric layer 6 is paved with a plastic film layer 7, the surface of the plastic film layer 7 is coated with a cement mortar sealing layer 8, triple waterproof effects are realized by utilizing the waterproof roll material layer 4, the plastic film layer 7 and the cement mortar sealing layer 8, so that the integral waterproof performance is improved, meanwhile, the hoisting stainless steel mesh layer 5 is paved on the surface of the waterproof roll material layer 4, because the stainless steel mesh layer 5 and the waterproof roll material layer 4 are in a local contact structure, the cement mortar sealing layer 8 can act on the hoisting stainless steel mesh layer 5, the geotechnical non-woven fabric layer 6 and the plastic film layer 7 due to the expansion stress generated by heated precooling, and certain deformation can occur on the hoisting stainless steel mesh layer, at this moment, because be local contact and be certain slip laminating form between hoist and mount stainless steel mesh layer 5 and the waterproof roll material layer 4, consequently the stress effect of the shrink of hoist and mount stainless steel mesh layer 5 or the expansion production all transmits for waterproof roll material layer 4 with faint form, the destruction to waterproof roll material layer 4 production is littleer like this to holistic intensity has been improved, hoist and mount stainless steel mesh layer 5 also can make things convenient for the hoist and mount installation in later stage simultaneously, wholly provides effectual adhering to and supporting.
