Description
Technical field
It is the utility model relates to the field of building materials, in particular to a kind of in city underground, highway, railway tunnel
Water-proof sheet material and its construction method.
Background technique
Currently, concealed tunneling structure is used in city underground, highway, Concerning Railway Tunnel Construction, it is as Figure 1-Figure 2, first
Lining structure reinforced concrete floor 2 at the beginning of first spraying one in the surface layer that tunnel outer is contacted with rock-soil layer 1；Then, it is laid with one layer
Common water-proof sheet material 3；A two lining structure reinforced concrete floors 2 ' are done outside common water-proof sheet material 3, i.e. completion tunnel structure.
But actually construction in, or even including all engineerings after, still occur in existing tunnel many places infiltration, leakage
The phenomenon that water.Therefore, it is necessary to engineers and technicians to carry out trapping operation everywhere, so that facility is spent in construction or operational process
A large amount of manpower financial capacity goes to repair.In particular, often occurring after having mended several infiltrations, leakage point, there are new infiltration, leakage again soon
Water spot occurs.The reason is that:
1, since inner lining structure construction is to carry out after the completion of water-proof sheet material construction, and two lining structures apply man-hour requirement elder generation
Assembling reinforcement structure, then casting concrete.Therefore, water-proof sheet material can be inevitably destroyed in constructing operation.
2, water-proof sheet material is the upper and lower surface plate of polyurethane material, and thickness is only 1.5 millimeters or so, it is easy to quilt
It destroys, is but difficult to be found.
3, since water-proof sheet material is a kind of polyurethane material, the inside and outside of water-proof sheet material is reinforced concrete structure, so
They are unlikely to be close combination between water-proof sheet material.
So once underground water penetrates into the outer layer of water-proof sheet material by first lining structure, it can be flowed everywhere along water-proof sheet material,
It punctures a little, will be leaked into from the outside of water-proof sheet material between water-proof sheet material and two linings, and accumulate stream in gap therebetween once encountering
It is dynamic.Once breaking through two lining structures, it just will appear infiltration or drainage.Engineers and technicians can only mend the breakthrough of two linings
It is good, but flowing ponding can still leak under the pressure of underground water to other local plays between water-proof sheet material and two linings.Therefore root
Originally leak again after two lining structure breakthrough leak repairings can not be solved the problems, such as.
Summary of the invention
It a kind of water-proof sheet material structure that is provided the purpose of the utility model is to overcome the deficiencies in the prior art and its applies
Work method.The utility model water-proof sheet material can be effectively prevented flows ponding in underground water between water-proof sheet material and two lining structures
Pressure under can be leaked to other local plays, therefore leak repairing need not be repeated again.
The technical solution of the utility model is:
A kind of water-proof sheet material has water-proof sheet material front and water-proof sheet material reverse side；It is uniformly provided on water-proof sheet material front
Several are with fin and its middle part is concave inward structure；Water-proof sheet material reverse side is planar structure.
Wherein, the water-proof sheet material is polythene material.
The water-proof sheet material with a thickness of 1~5 millimeter or so；Height of the fin away from concave inward structure bottom is 1
~2.5 centimetres；And the width of fin is identical as the thickness of water-proof sheet material.
The bottom of the concave inward structure is plane, and the medial surface angle of the plane and fin is 90 °；The plane and waterproof
Plate reverse side with a thickness of 1.5 millimeters or so.
The concave inward structure, is uniform arranged adjacent, and shape includes rectangle, honeycomb hexagon or other interior angles envelope
The polygonal shape closed.
A kind of construction method of water-proof sheet material, this method step include:
A, lining structure reinforced concrete floor at the beginning of spraying one in the surface layer that tunnel outer is contacted with rock-soil layer；
B, water-proof sheet material is set on first lining structure reinforced concrete floor upper berth；Water-proof sheet material reverse side and first lining structure reinforcing bar are mixed
Solidifying soil layer fitting；
C, the metal bar construction in two lining structure reinforced concrete floors is set in water-proof sheet material front；Then, it then pours
Concrete, so that concrete is embedded into the concave inward structure of water-proof sheet material, to form water-proof sheet material and two lining structure reinforcing bars are mixed
Solidifying soil layer is combined closely.
Utility model has the advantages that by fin, concave inward structure that the utility model is equipped on water-proof sheet material,
It solves problem in the prior art, is not in the prior art in the case where this anti-leakage structure of the utility model stops
The percolating water phenomenon everywhere occurred to need not carry out repeating leak repairing work, therefore greatly improves working efficiency, reduces
Cost.

Specific embodiment
With reference to the accompanying drawings of the specification and embodiment, the utility model is further described.
As Figure 3-Figure 4, the utility model water-proof sheet material 33 has water-proof sheet material front 33a and water-proof sheet material reverse side
33b；Be uniformly provided on the 33a of water-proof sheet material front several in the middle part of fin 332 and its be concave inward structure 331；Splash guard
Material reverse side 33b is planar structure.
Wherein, the water-proof sheet material 33 is polythene material.
The water-proof sheet material 33 with a thickness of 1.5 millimeters or so；The fin 332 is away from 331 bottom of concave inward structure
Height is 1~2.5 centimetre；And the width of fin 332 is identical as the thickness of water-proof sheet material 33.
The bottom of the concave inward structure 331 is plane, and the plane and the medial surface angle of fin 332 are 90 °；The plane
With water-proof sheet material reverse side 33b with a thickness of 1.5 millimeters or so.
The concave inward structure 331, is uniform arranged adjacent, and shape includes rectangle, honeycomb hexagon or other interior
The closed polygonal shape in angle.
The construction method step of the utility model, it includes:
A, lining structure reinforced concrete floor 2 at the beginning of spraying one in the surface layer that tunnel outer is contacted with rock-soil layer 1；
B, water-proof sheet material 33 is set on first 2 upper berth of lining structure reinforced concrete floor；Water-proof sheet material reverse side 33b and first lining are tied
Structure reinforced concrete floor 2 is bonded；
C, the metal reinforcing bar knot in two lining structure reinforced concrete floors 2 ' is first set in the upper surface of water-proof sheet material front 33a
Structure；Then, then casting concrete, so that concrete is embedded into the concave inward structure 331 of water-proof sheet material 33, to form splash guard
Material 33 is combined closely with two lining structure reinforced concrete floors 2 '.
When the underground water in soil layer once breaks through just lining structure reinforced concrete floor 2, water-proof sheet material 33 under its pressure
Leakage phenomenon occurs, the water of leakage, can only be in some concave inward structure in the case where the fin structure 332 of concave inward structure 331 stops
Accumulate in 331 bottom surface, or generates leakage in the point, but not channeling water occur and occur to leak everywhere and can not find leakage origin
The phenomenon that.
