Description
Technical field
Buildings waterproof field is the utility model is related to, more particularly to a kind of tunnel floor waterproof structure for deformation seams.
Background technology
Waterproof measure is weaker in current tunnel floor waterproof construction, the phenomenon of percolating water easily occurs, simultaneously existing
Some waterproof measures are also mainly to rely mainly on prevention, i.e., passive that the underground water for having pressure is blocked in outside tunnel floor, but tunnel is
Individual permanent century-old engineering, is acted on by hydraulic pressure, the phenomenon of percolating water occurs unavoidably for a long time.
Utility model content
The defects of the purpose of this utility model is to overcome prior art, there is provided a kind of waterproof measure is relatively strong, water-proof drainage
The tunnel floor waterproof structure for deformation seams being combined, the technical scheme of the tunnel floor waterproof structure for deformation seams are realized in
's：
A kind of tunnel floor waterproof structure for deformation seams, it is characterised in that：The waterproof construction includes structure base slab, the knot
Structure bottom plate includes left bottom plate and right bottom plate, and a movement joint is provided between the left and right bottom plate, is in lie on one's side among the movement joint
Concave shape structure, it is buried in being provided with above the concave shape to arrange waterstop, be provided with the movement joint at sealing
Back sticking type rubber fastening band, be disposed with below the back sticking type rubber fastening band waterproof roll extra play, waterproof roll layer,
Screed-coat and concrete cushion, handled with fluid sealant filleting at the upper sealing of the movement joint, at the movement joint intermediate gaps
Fill medium density polyethylene plate.
Further, the fluid sealant is polysulfide two-component fluid sealant.
Further, the width of the movement joint is 20~30mm.
Further, buried waterstop middle of arranging is provided with a filter to match with the movement joint size in described
Water bar.
Tunnel floor waterproof structure for deformation seams of the present utility model using waterproof roll, back-adhering waterstop, in it is buried can
Waterstop multiple waterproof measure is arranged, waterproof effect is preferable, while middle buried water stop is arranged to arrange waterstop, will can ooze
The water of leakage is by that can arrange waterstop guiding discharge, and the waterproof measure combined using anti-row, simple in construction firmly durability is preferable,
Water resistance at bottom deformation seam is obtained into larger improvement.

Embodiment
The utility model is described in further detail with specific embodiment below in conjunction with the accompanying drawings.
As shown in figure 1, a kind of tunnel floor waterproof structure for deformation seams, including structure base slab 1, the structure base slab 1 include
Left bottom plate 1a and right bottom plate 1b, is provided with a movement joint 2 between the left bottom plate 1a and right bottom plate 1b, among the movement joint 2
It is buried in being provided with above the concave shape to arrange waterstop 8, described 2 times sealings of movement joint in the concave shape structure lain on one's side
Place is provided with back sticking type rubber fastening band 7, the lower section of back sticking type rubber fastening band 7 be disposed with waterproof roll extra play 6,
Waterproof roll layer 5, screed-coat 4 and concrete cushion 3, handled with the filleting of fluid sealant 9 at the upper sealing of the movement joint 2, it is described
Medium density polyethylene plate is filled at the intermediate gaps of movement joint 2.
When it is implemented, the fluid sealant 9 is polysulfide two-component fluid sealant.
When it is implemented, the width of the movement joint 2 is 20~30mm.
When it is implemented, the buried middle of waterstop 8 of arranging matches provided with one with the movement joint size in described
Drainage bar.
When it is implemented, the drainage path of the waterproof construction is as described in Figure 2, by being buried in being arranged at movement joint 2
Formula can arrange waterstop 8 and lead percolating water row into the corrugated drain pipe 10 in drainage channel, then be entered by corrugated drain pipe 10
In the longitudinal drainage pipe 11 for entering tunnel internal.
Technology contents and technical characteristic of the present utility model have revealed that as above those skilled in the art still may base
The replacement and modification without departing substantially from the utility model in essence are made in teaching of the present utility model, therefore, the utility model protection
Scope is not limited to the content disclosed in embodiment, also including various replacements and modification without departing substantially from the utility model in essence.
