Description
Technical field
The utility model is related to underground construction field, particularly a kind of new underground project waterproof structure.
Background technology
Tunnels and underground engineering percolating water is a headache for perplexing brainstrust for a long time, is also work under current position
Prominent common quality defect and the problem urgently deeply solved in Cheng Jianzhu.The underground engineering of current Tunneling by mining method composite lining
The waterproof constructions for using waterproof roll to add non-woven geotextile, waterproof roll is generally macromolecule water-proof sheet material, such as all kinds more
Plastic plate, rubber slab etc..
It is summed up, the composite water-proof of splash guard+non-woven geotextile is used in underground engineering composite lining waterproof construction
Structure has following defect：
1. the material of itself can not be closely connected with concrete, the difficult requirement for meeting water blockoff, impact when installing, back side protrusion etc. is easily
Splash guard is punctured, causes leak；
2. require that waterproof surface smooth-going is neat, in case of wall concrete has compared with macroscopic-void and concavo-convex occasion, secondary lining extruding waterproof
Plate Tensile, easily makes splash guard rupture failure；
3. the junction surface between plate and plate, is the weak link of splash guard, high is required to construction precision, it is careless slightly, it can lead
Whole water-proof system is caused to fail.
The content of the invention
The purpose of this utility model is to provide a kind of new underground project waterproof structure, in order to eliminate composite water-proof volume
Defect of the material in composite lining underground engineering, seeks new waterproof construction scheme and substitutes old composite of water-proof coiled material waterproof
Scheme, new acrylic acid spray film waterproof construction reply construction environment without particular/special requirement, wide adaptability, uniform quality, good endurance,
The advantages of construction quick and convenient, good integrity.
To realize above-mentioned technical purpose and the technique effect, the utility model discloses a kind of new underground work
Journey waterproof construction, includes composite earthwork pad, hot melt gland, metal washer, nailing and acrylates spraying film waterproof, is combined
Geotechnique's pad is covered in gunite concrete surface, and hot melt gland is fixed on the surface of composite earthwork pad, and being fixed by nailing will
Composite earthwork pad is fixed on gunite concrete surface, and metal washer is arranged between nailing and hot melt gland, acrylates spray
The injection of film waterproof layer is covered in hot melt gland.
Wherein, composite earthwork pad sets the impermeable material that one layer of geomembrane is composited in the middle of two layers of geotextile,
Its mass area ratio is more than 300g/m2。
Wherein, hot melt gland is that low density polyethylene (LDPE) high-temperature injection heats circular cover.
Wherein, hot melt gland density of setting is 3~4/m of average vault point2, 2~3/m of edge point2, in quincunx arrangement,
And fixation of being embarked on journey above and below left and right.
It is preferred that, acrylates spraying film waterproof thickness is 2-3mm, and lap width is not less than 100mm.
The utility model has the advantages that：
1. the utility model is by spraying the research that film waterproof construction is constituted to tunnel acrylates, ensure waterproof quality,
On the premise of economy and exploitativeness, optimal waterproof construction scheme is proposed, by research, by composite earthwork pad and propylene
The tunnel recombination waterproof construction of hydrochlorate spraying film waterproof composition has good water resistance.
2. by the underground project waterproof structure rationally designed, seen by the actual operating result of case history, the new technology
The spray waterproof effect of film waterproof construction of introducing, globality, the technical difficulty of construction and speed, the utilization rate of material etc. it is excellent
In the composite water-proof structure of splash guard and non-woven geotextile.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
Critical piece symbol description:

Embodiment
In order that the purpose of this utility model, technical scheme and advantage are more clearly understood, below in conjunction with accompanying drawing and implementation
Example, the utility model is further elaborated.
As shown in figure 1, the invention discloses a kind of new underground project waterproof structure include composite earthwork pad 1,
Gland 2, metal washer 4, nailing 3 and acrylates spraying film waterproof 5 are heated, composite earthwork pad 1 is covered in gunite concrete 6
Surface, hot melt gland 2 is fixed on the surface of composite earthwork pad 1, is fixed by nailing 3 composite earthwork pad 1 being fixed on spray
The surface of concrete 6 is penetrated, metal washer 4 is arranged between nailing 3 and hot melt gland 2, the injection covering of acrylates spraying film waterproof 5
In hot melt gland 2.
Composite earthwork pad 1 sets the impermeable material that one layer of geomembrane is composited in the middle of two layers of geotextile, its list
Position area quality is more than 300g/m2, hot melt gland 2 is that low density polyethylene (LDPE) high-temperature injection heats circular cover, and density of setting is
