Waterproof roll enhancement layer 8 is set on the outside of rubber fastening band 6;
Waterproof roll enhancement layer 8 uses 4mm thickness high polymer SBS modified asphalt waterproof coiled material, using Hot-melt construction, by change Coiled material is cut into 1000mm wide coiled material extra play by shape slit shape, and coiled material is formed by bending baltimore groove at deformation joint medium position, Flexible crook reason is done, slot opening is upward.
Waterproof layer 9 is set on the outside of waterproof roll enhancement layer 8;
Waterproof layer 9 includes two layers;
9 first layer of waterproof layerUsing 4mmThick high polymer SBS modified asphalt waterproof coiled material;
9 second layer of waterproof layerUsing 3mmThick high polymer SBS modified asphalt waterproof coiled material;
Waterproof layer 9 use Hot-melt construction, coiled material is formed by bending baltimore groove at deformation joint medium position, do stretch it is curved Processing, slot opening are upward.
Waterproof roll enhancement layer: conscientiously checking whether outer patch waterstop has disrepair phenomenon before construction, by damaged waterstop It is replaced at position;Then base cleaning is clean, guarantee that base is dry, with long handle round brush by base treatment agent brushing in base Surface will brush uniformly, must not leak brush or show-through.
Degree of drying, which must be reached, by 6h or more after base treatment agent brushing can implement Hot-melt construction.Method is Coiled material is first cut into 1000mm wide coiled material extra play by deformation joint shape, 400mm wide is respectively spread on two side plane of deformation joint, depending on ruler It after very little, shape is suitable, then by the bottom surface (one side for having hot melt adhesive) of coiled material, is toasted with hand-held benzine blow lamp, to its bottom surface in molten Melt state, can be pasted onto immediately in the base for having brushed 1 sealing material, and be compacted paving jail, in deformation joint position Portion is made into stretch and curved prevents from settling caused destruction.
Construction of waterproof layer: in processed good and dry substrate surface after waterproof reinforced layer acceptance(check), according to selected volume The width of material reserves overlapping the slot size, and the reference line bullet of paving coiled material is good, to carry out installation of membrane construction by this reference line. Entire volume coiled material is placed in paving starting point, is directed in base the good chalk line of bullet, rolling is opened a book material about 1m, by 1 people station coiled material just This 1m coiled material pull-up, another 1 people station are held liquefied gas flame gun coiled material bottom surface (having hot melt adhesive), flame are made to be directed at coiled material by face Coiled material bottom surface and base face are heated simultaneously with basal plane junction, viscous paving are carried out in molten to coiled material bottom surface glue, then by a people Compacting is exhausted to the coiled material of paving with hand-held pressure roller, when being taped against the remaining about 30cm of coil end in this way, coil end is turned over It is molten roasting to be placed on thermal insulation board row again, end coiled material is finally spread into jail compacting, it is important to note that in first and second time waterproof layer paving construction In, coiled material is formed by bending baltimore groove at deformation joint medium position, flexible crook reason is done, uses plastic adhesive tape by φ 50mm afterwards Sticking plaster be pasted onto waterproof roll groove, slot opening must be upward, when carrying out waterproof protective layer construction by sticking plaster In casting concrete, prevent later period malformation from causing waterproof damage layer.
Waterproof protective layer 11 is set on the outside of waterproof layer 9;
Waterproof protective layer 11 uses 70mm thickness C20 commodity pea gravel concreten, before carrying out pouring construction, first uses plastic cement The foamed plastic rod 10 of φ 50mm is pasted onto waterproof roll and stretched in curved groove by band and special glue, and rear concrete topping is according to mixed Solidifying soil is returned according to 1% levelling, plastering.
Water-storing test: going through whether waterproof layer surface has disrepair phenomenon after construction, after perception acceptance(check) The position carries out water-storing test, and water storage height exceeds highest point 50mm, and water storage duration 24 hours, absolutely without can after leak source Carry out the next step implementation.
The above described is only a preferred embodiment of the present invention, not making in any form to structure of the invention Limitation.Any simple modification, equivalent change and modification to the above embodiments according to the technical essence of the invention, Belong within the scope of technical solution of the present invention.
