Detailed description of the invention
Fig. 1 is the structure chart of pile crown waterproof construction.
Specific embodiment
As shown in Figure 1, a kind of pile crown waterproof construction, including, 1 upper surface of pile crown is inserted with reinforcing bar 2,2 excircle set of reinforcing bar
Equipped with hydro-expansive rubber item 3,1 excircle of pile crown is successively arranged concrete cushion 4, waterproof coating 6, waterproof mortar from bottom to up
Layer 7 and pea gravel concreten 10,7 longitudinal section of waterproof mortar course are L-type, and L-type right angle is equipped with waterproof sealing cream 9, and L-type lower end surface is solid
Surely it is connected with and delays swollen rubber strip 5, waterproof coating 6 is square waveform between concrete cushion 4 and waterproof mortar course 7, prominent
Part is laid on 1 excircle of pile crown and upper surface.Sealing compound main constituents are asphalt and polymer rubber modifying agent.
Wherein asphalt is also the main constituents of self adhesive material, and self-adhering polymer modification bitumen similar compatibility, this coating and
Overlap joint between self-adhesive coiled material can be very tight with overlapped, is capable of forming whole waterproof system, guarantees that the waterproof at pile crown can
By property.
Waterproof coating is cementitious capillary waterproofing material, by one group of specially treated activity of portland cement
The dusty material of compound and quartz sand composition.Cementitious capillary waterproofing material acts on concrete structural surface
When, active chemistry is permeated by carrier to the capillary channel of inside concrete, with the lime molecule and water wherein to dissociate
Molecule occurs instead, to form crystalline solid not soluble in water, and crystalline solid can penetrate into the deep layer of concrete, clog capillary channel and hole
Gap, and be left permanently in concrete, to keep concrete fine and close, the infiltration of water is prevented, plays permanent sealing concrete
Effect.
Smooth closely knit placement slow expansion type water-swelling rubber water bar at pile crown reinforcing bar and around pile crown.
1), the barrier paper being wrapped in outside water-swelling rubber water bar is torn, sealing rod is directly installed in groove
On concrete surface, in order to avoid dislocation.
2) water-swelling rubber water bar upper surface, is rolled with roller, keeps sealing rod closely connected, secured with concrete surface.
3) when, sealing rod needs connector, it will overlap etc. within the scope of two sealing rod end 6cm and be cut into inclined-plane by knife respectively
Or 1/2 is flattened, overlapping overlap joint is in close contact it with concrete surface with hand pressure up and down, then is followed closely in the middle part of overlap joint with cement nail
On concrete or horizontal misconnection 6cm or more, there must not be gap between the sealing rod of two, misconnection position.
4), sealing rod is forbidden using docking, in order to avoid misplace to form " breach " in casting concrete.
The preparation of waterproof coating penetration crystallization type water proofing paint: 1) by waterproof coating permeable crystalline waterproofing material and completely
Water concocting (required in water salt-free and without harmful components).It is matched when mixing by producer, vaned stir can be loaded into electric hand drill
It mixes stick or puts on rubber gloves hand and trowel to mix.It should not once adjust more, to be finished in 20 minutes；
2) cementitious capillary waterproofing material is constructed: by deployed cementitious capillary waterproofing material hair on the neck
Hairbrush is uniformly painted on pile crown basal plane, and when cementitious capillary waterproofing material brushing should be noted that coating will be uniformly, no
Holiday.It should be noted that when brushing and carry out reuse point power, to guarantee to coat at bumps.Pile crown recess cannot have cement-based penetrant knot
The blocked up deposition of crystal form waterproof material, otherwise may crack at accumulation.When applying the second layer, have to after waiting first layers pre-hardening still
It is carried out in when dampness, as too dry, should first spray a little water and basal plane is moistened.
3) it must be conserved with clean water and after initial set using atomizing in maintenance processes, have to avoid coating quilt
It destroys.It need to generally spray water daily 3 times, continuous 2-3 days, to be sprayed several times in hot day or dry weather more, prevent coating from drying too early.
Smear waterproof mortar
1) it is levelling to smear the thick high-intensitive polymer cement mortar progress of 20mm, is applied in brushing cement-base infiltration crystallization type water-proof
Material.
2) construction of polymer cement mortar waterproofing layer thickness single layer is preferably 6-8mm；
(3) the double-deck construction is preferably 10-12mm；
(4) the cement mortar waterproofing layer thickness for mixing additive, admixture etc. is preferably 18-20mm.
Paste extra play waterproof
1) waterproof roll is cut into the size of 1m × 1m.The part of coiled material central diameter 0.5m is determined so as to waterproof
Coiled material can pack into.
2) it requires to exclude air below coiled material when waterproof roll paving, slowly firmly be flattened with dedicated pressure roller or hand.Coiled material
Surface must not have distortion, fold and foaming phenomena.
3) it then, first by the completely viscous paving of strip coiled material hot melt in pile crown side, cuts apart with a knife or scissors part and is completely sticked in planar base layer,
Again by round coiled material hot melt it is full viscous and in side web plane part adhesive it is secured.Note: rectangle coiled material and round coiled material are cut out
Open the overlap joint that be partially staggered.
Brush seals cream process
After waterproof roll packs into, waterproof sealing cream is coated with brush at waterproof roll and pile crown closing in, it is desirable that is brushed equal
Even, closing in sealed width 0.01m is to guarantee that coiled material seals.
7 upper surface of waterproof mortar course is fixedly connected with waterproof roll layer 8.Waterproof roll is polymerize using double-sided self-adhesive
Object modified bituminous pitch coiled material is using polyester fiber non-woven fabric as tire base, and elastomer (SBS) modified pitch is dip-coat material, upper table
Face, lower surface apply self-adhesive rubber asphalt and attached strippable painting silicon isolation film or painting silicon barrier paper are made as anti-sticking isolated material
A kind of double-sided self-adhesive waterproof coiled materials.
Two right-angle sides of the waterproof sealing cream 9 and waterproof mortar course 7 form sector structure.
Swollen 5 one side end face of rubber strip of delaying is bonded with 1 outer circumference surface of pile crown.
