Description
Technical field
The present invention relates to technical field of building construction, be specifically related to one subsiding crack height waterproof construction removably and
Construction method.
Background technology
Building needs to design subsiding crack in certain length according to the requirement of design and construction technical specification.Prior art
In in subsiding crack, generally cement the insulation materials such as soft polyethylene, then fixing flexible rubber fastening band, finally use monoblock to sink
Fall seam cover plate covers gap.But the waterproof effect of this kind of structure is bad, easily leaks, after its flexible rubber waterstop used
Phase can make flexible rubber waterstop tear because foundation deformation, make waterproof construction lose waterproof action；The monoblock sedimentation that it uses
Seam cover plate easily damages under the stress effect of subsoil water, makes reduce the service life of waterproof construction.And existing subsiding crack is waterproof
Structure is once damaged, and keeps in repair extremely difficult, and maintenance process is wasted time and energy, and maintenance cost is high.
In the work progress of existing settlement joint water-proof structure, owing to the elasticity of flexible rubber waterstop is big, it is difficult to make
Flexible rubber waterstop is the most closely fitted with basal plane, bring leak, the hidden danger of water of leaping up.
Summary of the invention
Easily leaking to solve settlement joint water-proof structure, waterproof effect is bad, and service life is short, and maintenance is tired after leaking
Difficult technical problem, it is an object of the invention to provide a kind of detachable subsiding crack height waterproof construction and construction method thereof, effectively
Preventing basement subsiding crack from leaking, waterproof effect is reliable, and is demountable structure for subsiding crack height waterproof construction of the present invention,
Once there is drainage, be highly susceptible to maintenance, time saving and energy saving and cost-effective.
In order to solve above-mentioned technical problem, the technical solution adopted in the present invention is: a kind of detachable subsiding crack height is prevented
Water-bound, is provided with chuck at the concrete wall top of subsiding crack both sides, is embedded with water expandable waterstop in chuck, is meeting
Water expansion sealing strip is provided above covering the rubber water-proof plate on subsiding crack, and it is empty that rubber water-proof plate includes being arranged on subsiding crack
Intracavity and concave part that cross section is V-type and two fixed parts being connected with concave part two side respectively, on two fixed parts
Side is respectively arranged with and leaves the gap being positioned at above subsiding crack between steel plate, and two block plates, and described steel plate and fixed part pass through
Expansion bolt is fixed on concrete wall.When there being water to enter in subsiding crack, two water expandable waterstop 3 can occur swollen
Swollen, and block above subsiding crack, prevent from leaking, and the rubber above seal plate 1 of expansion sealing strip 3 can further anti-leak-stopping
Water, good water-proof effect.
The width in the gap between described two block plates is 10-20mm, makes there is the flexible surplus of deformation between two block plates 2.
Using two block plates to replace monoblock subsiding crack cover plate of the prior art, two block plates can be with concrete wall differential settlement
Deformation, will not damage because of the stress effect of subsoil water, substantially prolongs the service life that waterproof construction of the present invention is made.
Described concave part is formed by fixedly connecting by two rubber slabs, and sets in 10 ° of-170 ° of angles between two rubber slabs
Put.
Described rubber water-proof plate is formed in one structure, make rubber water-proof plate have while keeping toughness higher by force
Degree.
The construction method of described a kind of detachable subsiding crack height waterproof construction, comprises the following steps:
Concrete wall end face is also polished flat, at two concrete wall end faces by step one, cleaning polishing concrete wall
Cut respectively near one end of subsiding crack and dig out chuck, the sidewall that chuck is relative with subsiding crack uniformly brushes binding agent, at card
On two other sidewall of platform, one end away from subsiding crack is uniformly brushed and is brushed the area of binding agent on binding agent and each sidewall and be
The 1/3-1/2 of its gross area, then embeds water expandable waterstop in groove, and by fixing for water expandable waterstop compacting,
Until water expandable waterstop is with concrete wall bonding firmly；
Step 2, the concave part of rubber water-proof plate is placed in subsiding crack cavity in and the fixed part of rubber water-proof plate is placed in coagulation
On cob wall body end face, then to be laid on rubber water-proof plate by two block plates and make the gap width between two block plates be 10-
20mm, punches by upper surface of steel plate vertically downward with drilling equipment, and the drill bit of perforating device is successively at steel plate, rubber water-proof
Get bolt hole on plate and concrete wall, after punching, remove steel plate and rubber water-proof plate, standby；
Fill in epoxy resin in step 3, bolt hole on concrete wall, then one end of expansion bolt is vertically pressed on
Until expansion bolt is firm with concrete wall bonding in bolt hole；
Step 4, to concrete wall end face spray uncured rubber asphalt waterproof coating, with by concrete wall and expanding screw
The gap between gap, concrete wall and water expandable waterstop between bolt and the closure of the crackle on concrete surface；
Step 5, on the expansion bolt body of rod, spray uncured rubber asphalt waterproof coating, then at the bolt of rubber water-proof plate
Uncured rubber asphalt waterproof coating is all sprayed on the bolt hole inwall of hole inwall and steel plate, more successively by rubber water-proof plate and steel
Plate is set on expansion bolt by bolt hole and rubber water-proof plate and steel plate is fixed by nut.
Compared with prior art, the method have the advantages that detachable subsiding crack height of the present invention is prevented
Water-bound, good water-proof effect, antileaking.Use the rubber water-proof plate of special construction, can be with the dilatation of concrete wall
And deformation, be hardly damaged inefficacy, and its tear resistance be strong, can with expansion bolt with the use of, then make demountable structure,
Facilitating later period maintenance, make later period maintenance process time saving and energy saving, maintenance cost is low.The present invention uses two block plates to replace prior art
Middle monoblock subsiding crack cover plate covers gap, and preset clearance between two block plates, makes between two block plates at subsoil water
Deform under stress effect and stretch, be hardly damaged and lost efficacy, extending the service life of waterproof construction of the present invention.
In work progress, the sidewall that chuck is relative with subsiding crack is uniformly brushed binding agent, chuck two other
On sidewall, one end away from subsiding crack is uniformly brushed and brushed the area of binding agent on binding agent and each sidewall is its gross area
1/3-1/2, is firmly bonded in then water expandable waterstop embeds groove, thus ensure that water expandable waterstop is near heavy
One end of fall seam can free wxpansion, it is to avoid its fixing end tear or displacement during water expandable waterstop water-swellable, extends
The service life of water expandable waterstop.
The bolt hole inwall of the expansion bolt body of rod and rubber water-proof plate and steel plate sprays uncured rubber asphalt prevent
Water paint, makes the gap between expansion bolt and bolt hole be blocked, strengthens waterproof effect.
