Description
Technical field
The present invention relates to tunnel waterproofing engineering technical fields more particularly to a kind of self-adhesive pad formula waterproof roll to spread extension side
Method.
Background technology
Needed in constructing tunnel, before Tunnel Second Lining Construction to after preliminary bracing tunnel side wall and arch prevent
Drainage construction, to prevent tunnel from percolating water phenomenon occur during operation.Current waterproof type is supporting in the early stage and two
Geotextiles and splash guard are set gradually between secondary lining cutting to realize waterproof.Generally use is laid in the installation of splash guard in existing tunnel
The modes such as gallus-type is installed and hot melt washer is laid with.
Gallus-type splash guard be production when according to constant spacing splash guard the compound upper suspender belt of one side, in engineering construction
In, hook is squeezed on Tunnel, and then the suspender belt of splash guard is tied on hook, the splash guard and tunnel installed in this way
Road preliminary bracing is not closely connected, and especially in construction tunnel arch ring concrete, the dead weight of concrete is easy splash guard to pull down
Come, do not have waterproof action and easily forms lining cutting back cavity in arch.Gallus-type splash guard is not elastic easily-controllable when fixed
System, and there are clothes-hook small, insecure, the frenulum sheets that punctures splash guard, frenulum and splash guard junction forced area in suspention
The shortcomings of body intensity is insufficient, easy fracture.
The splash guard that washer is laid with is heated, is that first paving hangs permeable geotextiles on supporting surface in the early stage, then lays hot melt
Washer, then splash guard and hot melt washer are welded together the two using heat melting device, when this splash guard paving hanging method is constructed
Temperature is not easy to control, is easy burn-through splash guard, and solder joint fastness is poor, and heats washer paving mode and require height, needs to make
The sweat soldering of electricity consumption thermocompression bonding device, operation are more complex, influence construction efficiency, and mutually overlap joint welding waste is serious, uneconomical.
Invention content
In order to solve the above technical problem, the present invention provides a kind of paving hanging method of self-adhesive pad formula waterproof roll,
Include the following steps：
(1) concrete surface of Tunnel is levelling；
(2) filter layer being laid with for filtering fine particle is fixed in the concrete surface of the preliminary bracing；
(3) non-adhering side of multiple self-adhesive pads is respectively fixed on the filter layer, the adhesive surface of another side is used for
It is bonded waterproof roll；Preferably, fixing glue is passed perpendicularly through to self-adhesive pad and filter layer successively to the coagulation of the preliminary bracing
In soil, make the non-adhering side of multiple self-adhesive pads is fixed respectively to amplexiform on the filter layer, the adhesive surface of another side glues respectively
Connect waterproof roll.
The paving hanging method of self-adhesive pad formula waterproof roll of the present invention, self-adhesive pad carry out waterproof roll and filter layer
Reliable bonding, to be connected as an entirety with preliminary bracing, and then effectively prevents underground water and leaks out in tunnel, play
Good waterproof action；The installation method is simple for process, easy to operate, and of low cost, set waterproof construction intensity
Height, durability and good water-proof effect, and facilitate repair, effective guarantee construction quality.
The method of the invention, step (2) the fixed paving mode are：Multiple fixing glues are sequentially passed through respectively described
The concrete surface of filter layer and preliminary bracing, makes filter layer be fixed on the concrete surface of preliminary bracing, and ensures described
The head of a nail, filter layer and the concrete surface of preliminary bracing of fixing glue amplexiform successively.So that filter layer is tight with preliminary bracing
Close connection, bonding strength further increase.
The method of the invention, in step (3), multiple self-adhesive pads are evenly spaced to be distributed on filter layer.
The method of the invention, the self-adhesive pad are the square gasket that the length of side is 5~20cm, and in the filter layer
On laying density be 1~5/m2；Or, the self-adhesive pad is the circular gasket of a diameter of 5~20cm, and in the filtering
Laying density on layer is 1~5/m2.So set, while ensuring good bonding effect, production further reduced
Cost saves spending.
The method of the invention, the filter layer is non-woven fabrics, and thickness is 0.2~1.0cm.The setting of the non-woven fabrics
The fine particle in underground water is effectively filtered, it is ensured that underground water is efficiently and rapidly discharged.
The method of the invention, the waterproof roll are splash guard, drain bar or drainable waterproofing plate.The preferably anti-row of convex hull formula
Water plate, the convex hull formula drainable waterproofing plate have both the double action of waterproof and draining, reduce the aggregation of underground water.
Further, the convex hull formula drainable waterproofing plate is equipped with the identical convex hull of multiple arrangement uniform intervals, the convex hull
Top it is Nian Jie with the adhesive surface of the self-adhesive pad.The channel of a flow is formd between each convex hull, underground water is thus
Channel can quickly flow out, and reduce underground hydropexis and corrode caused by waterproof construction.
Preferably, the density of convex hull is 1000~3000/m on the convex hull formula drainable waterproofing plate2；And/or the convex hull
For hollow structure, and top seal, bottom are open.
Preferably, the convex hull is hemispherical or round table-like.
It is furthermore preferred that a diameter of 1.6~2.4cm of the hemispherical convex hull；Or the basal diameter of the round table-like convex hull
For 1.6~2.4cm.
The above-mentioned technical proposal of the present invention has the advantages that：The installation method is simple for process, easy to operate, setting
Self-adhesive pad make Nian Jie reliable between the splash guard and filter layer, will not occur leak easily, closely be connected as entirety, no
Channeling water can be formed, it is easy to maintenance, ensure construction quality.
