Abstract
The open tunnel waterproofing construction of the utility model; tunnel is followed successively by structure wall layer, 20mm waterproof polymer mortar, 4mm wet-laid process self-adhesion asphaltic base polyester blank waterproof roll, topping from the inside to the outside; be sewn in structure wall along tunnel circumferential deformation and arrange buried steel plate water stopper and back-adhering waterstop in a circle, transversely, longitudinal constuction joint arranges steel plate luting waterstop and cement based crystal permeability type water-repellent paint.The utility model is considered as a system engineering tunneling and underground engineering waterproof.According to engineering specific requirement and situation, waterproof principle, waterproofing design, Material selec-tion, Waterproof Construction Technique, waterproof construction management, the selection of waterproof construction troop etc. are all included in water-proof system, sets up complete water-proof system.
Description
Technical field
The utility model relates to tunnel waterproofing construction.
Background technology
Tunnel water proofing technology is technical difficulty in Tunnel Design and emphasis always, and water seepage of tunnel in constructed item, to leak also be a kind of common quality defect.There is following Railway Project in existing tunnel waterproofing design: 1) water-proof system is not considered as a system engineering.2) the continuing to bring out of waterproof material and technology, for selecting to provide favourable condition and space, but also makes selection add difficulty.3) tunnel recombination formula waterproofing course and deformation joint construction control not strict.4) impermeable structure fails to reach due effect.5) additional waterproofing layer selects to fail incorporation engineering concrete condition.
Utility model content
For solving the technical problem of tunnel water proofing, the utility model object is to provide a kind of waterproof effect preferably tunnel waterproofing construction.
For solving the problems of the technologies described above, the utility model by the following technical solutions:
Tunnel waterproofing construction; it is characterized in that; described tunnel is followed successively by structure wall layer, 20mm waterproof polymer mortar, 4mm wet-laid process self-adhesion asphaltic base polyester blank waterproof roll, topping from the inside to the outside; be sewn in structure wall along tunnel circumferential deformation and arrange buried steel plate water stopper and back-adhering waterstop in a circle, transversely, longitudinal constuction joint arranges steel plate luting waterstop and cement based crystal permeability type water-repellent paint.
Wherein, described middle buried water stop be 350mm wide can slip casting rubber watertight strip.
Wherein, the rubber putty that described steel plate luting waterstop is wrapped up in entirely by 0.6mm steel plate and outside thereof forms.
Wherein, described cement based crystal permeability type water-repellent paint width is 600mm.
Compared with prior art, the utility model has following beneficial effect:
The utility model is considered as a system engineering tunneling and underground engineering waterproof.According to engineering specific requirement and situation, waterproof principle, waterproofing design, Material selec-tion, Waterproof Construction Technique, waterproof construction management, the selection of waterproof construction troop etc. are all included in water-proof system, sets up complete water-proof system.Composite water-proof is emphasis of the present utility model, namely based on concrete structure self-waterproofing, at upstream face additional flexibility waterproofing course, forms the waterproof defence line of a rigid flexible system.

Detailed description of the invention
By describing technology contents of the present utility model, structural feature in detail, realized object and effect, accompanying drawing is coordinated to be explained in detail below in conjunction with embodiment.
Referring to Fig. 1 to Fig. 6, is the utility model tunnel water proofing plan.Tunnel waterproofing construction; it is characterized in that; described tunnel is followed successively by structure wall layer, 20mm waterproof polymer mortar, 4mm wet-laid process self-adhesion asphaltic base polyester blank waterproof roll, topping from the inside to the outside; be sewn in structure wall along tunnel circumferential deformation and arrange buried steel plate water stopper and back-adhering waterstop in a circle, transversely, longitudinal constuction joint arranges the cement based crystal permeability type water-repellent paint of steel plate luting waterstop and 600mm width.
In the above-described embodiments, middle buried water stop have employed 350mm wide can slip casting rubber watertight strip, the telescopicing performance that rubber has meets the deform in same pace needs of concrete shrinkage; The feature supplements of steel plate and concrete tight bond General Purpose Rubber waterstop and concrete binding is strong, easily slippage cause the deficiency of infiltration, the Grouting Pipe on both sides can be utilized to carry out slip casting shutoff to leakage at any time simultaneously.The back-adhering waterstop that face is arranged near water adds refuses outlet capacity outside deformation joint.
Transversely, longitudinal constuction joint arranges steel plate luting waterstop and cement based crystal permeability type water-repellent paint.The rubber putty that steel plate putty is wrapped up in entirely by 0.6mm steel plate and outside thereof forms, general steel plate water stopper easily causes concrete to be engaged insufficient, steel plate easy-to-rust with steel plate, the putty of steel plate outsourcing not only can weaken the degree of steel plate corrosion, and the water swelling ability of self can be utilized, filling, because being engaged the not enough weakness zone formed, ensure that the validity of waterproof.
The utility model is considered as a system engineering tunneling and underground engineering waterproof.According to engineering specific requirement and situation, waterproof principle, waterproofing design, Material selec-tion, Waterproof Construction Technique, waterproof construction management, the selection of waterproof construction troop etc. are all included in water-proof system, sets up complete water-proof system.Composite water-proof is emphasis of the present utility model, namely based on concrete structure self-waterproofing, at upstream face additional flexibility waterproofing course, forms the waterproof defence line of a rigid flexible system.
The above; be only the utility model preferably detailed description of the invention; but protection domain of the present utility model is not limited thereto; anyly be familiar with those skilled in the art in the technical scope that the utility model discloses; the change that can expect easily or replacement, all should be encompassed within protection domain of the present utility model.Therefore, protection domain of the present utility model should be as the criterion with the protection domain of claim.
