Detailed Description

The technical solutions of the present invention are further described in detail below with reference to the accompanying drawings, but the scope of the present invention is not limited to the following.

As shown in fig. 1 to 2, a waterproof and drainage plate with drainage function, including waterproof board 1, drainage board 2, a plurality of waterproof strips 3 and a plurality of bump 4, a plurality of bump 4 sets up between waterproof board 1 and drainage board 2, gap 5 between a plurality of bump 4 is used for the drainage, the one side that waterproof board 1 was kept away from to drainage board 2 is provided with a plurality of T type waterproof strips 3, a plurality of T type waterproof strips 3 pass through concrete placement with the two linings in tunnel and are in the same place, install the drain pipe 6 that is used for the drainage between waterproof board 1 and the drainage board 2. This prevent drain bar aim at solves the current poor difficult problem that leads to the percolating water phenomenon to frequently appear of construction joint water-proof effects, through should prevent the drain bar at construction department installation, can provide a drainage channel for passing the groundwater that the waterproof board goes on construction joint department, and then solves the phenomenon of groundwater along the construction joint seepage.

Further, this waterproof board is when construction concrete implementation, and the waterproof board 1 of this water drainage board is kept away from the smooth setting of a side of water drainage board 2, and 1 smooth side of waterproof board and tunnel are first to be equipped with geotechnological cloth between propping up, and 1 hoop both sides of waterproof board pass through the hot melt ware and prevent that water drainage board hot melt bonds together with other, play whole water-proof effects.

The water of infiltration first prop gets into between waterproof board and the secondary lining in waterproof board damaged position department, groundwater flows in the waterproof board that sets up at the construction joint along waterproof board and secondary lining crack, enter into this gap 5 between the waterproof board bump 4, simultaneously in the design, bond a plurality of bumps 4 and waterproof board 1 and drain bar 2 together, bump 4 highly be 0.5~1.0cm, can guarantee like this that there is enough big space to let the water of infiltration between gap 5 flow. This prevent drain bar still is equipped with exhaust drain pipe 6 in the gap 5, this drain pipe 6's one end is built-in 0.5~1.0m between waterproof board 1 and drain bar 2 and link up mutually with gap 5, the short side wall of two liners is extended to drain pipe 6's the other end for with the water of gap 5 to escape canal, avoid permeating too much can not in time discharge in this prevents the water drain bar, because water pressure is too big and ooze from the construction joint, influence the safety in tunnel. And all embedded steel wire protection network in the surface of this waterproof board 1 and the drain bar 2 of preventing the drain bar, itself prevent that the drain bar adopts flexible material to make, long-time because extrusion deformation can lead to the fact the damage to preventing the drain bar, all embedded steel wire protection network in the surface of waterproof board 1 and drain bar 2 can increase this flexibility and the connectivity of preventing the drain bar, increase its life-span of using.

Furthermore, the waterproof plate 1, the drainage plate 2 and the solid salient points 4 are firmly bonded together, a drainage gap is formed in the middle, the height of the solid salient points 4 is determined according to the drainage requirement, the height of the solid salient points is mainly 0.5-1.0 cm, and the solid salient points, the waterproof plate 1 and the drainage plate 2 form a whole to form the waterproof and drainage plate with the drainage function. The drainage plate 2 side that has the drainage function has multichannel T type waterproof strip 3, and waterproof plate 1 keeps away from drainage plate 2 one side smooth, and in the actual engineering, have waterproof strip 3 pour together with two linings, prevent that groundwater from following lining and the waterproof and drainage inter-plate clearance of installation and permeating to the construction joint, and smooth one side of waterproof plate 1 is close to first branch. Generally, this prevent drain bar has functional part width 1.0m, prevents drain bar 2.0m, in the waterproof board of actual tunnel is laid, meets the construction joint, cuts off at each 1.0m department of construction joint both sides and prevents the drain bar, carries out the overlap joint with another one again, requires that overlap joint length is not less 5 cm. After using this prevent drain bar with drainage function, construction joint department follows drainage and waterproof principle that combines together, possesses the dual guarantee of waterproof drainage, in case tunnel groundwater breaks through the waterproof board, just can provide a drainage channel for passing the groundwater that the waterproof board carried on construction joint department, intercommunication hole between waterproof board and the unsmooth drain bar of preventing promptly, through short side wall department drain pipe outflow lining cutting, thereby play construction joint department drainage effect, reduce construction joint department water pressure, avoid the percolating water to take place. The waterproof and drainage plate greatly reduces the construction difficulty at the construction joint and is beneficial to improving the concrete compactness at the construction joint, thereby improving the construction quality, indirectly improving the lining waterproof effect at the construction joint and reducing the occurrence of water leakage.

The foregoing is illustrative of the preferred embodiments of this invention, and it is to be understood that the utility model is not limited to the precise form disclosed herein and that various other combinations, modifications, and environments may be resorted to, falling within the scope of the concept as disclosed herein, either as described above or as apparent to those skilled in the relevant art.
