The invention discloses a kind of Cracks On Concrete Floors reinforcement process, belong to floor field of reinforcement, its step includes:Construction hole is drilled through in cracks on floor slab；Back and forth washed by water to construction hole again；In construction hole site installation grout nipple；In cracks on floor slab surface smear sealing compound；Grouter connection grout nipple carries out pouring into cement mortar.This kind of Cracks On Concrete Floors reinforcement process, mixed mud cracks on floor slab can be sealed and reinforced.
Description
Technical field
The present invention relates to floor field of reinforcement, more particularly to a kind of Cracks On Concrete Floors reinforcement process.
Background technology
Concrete cracking is a world-famous puzzle, and wanting not ftracture is nearly impossible, and cracking has on a variety of floors
There is surface crack to also have through crack, as long as it is all acceptable that country is required of surface crack no more than 0.3mm now,
If this factor of through crack just has, it is enough.Needed in raw material water it is bigger easily cracking, mainly powder, cement,
Miberal powder, flyash etc., also there is certain relation with sandstone；Additive also has a powder, the larger easy cracking of self-constriction, such as
Red flyash and sandstone；Middle modulus of fineness also easily ftractureing less than 2.6, additive usage is larger also easy to produce cracking；
Also the ratio of mud also has an impact, especially summer because moisture loss influence it is bigger；In addition also have and construct, such as pump
When add water, vibration is insufficient, and the unreasonable late maintaining of molding not enough can all cause to ftracture, and design aspect design portion is rationally led
Cause cracking.
The content of the invention
It is above-mentioned to solve the problems, such as, the invention provides a kind of Cracks On Concrete Floors reinforcement process, mixed mud can be sealed
Tulou plank split is reinforced.
The technical solution used in the present invention is：A kind of Cracks On Concrete Floors reinforcement process, its step include:In floor
Crack drills through construction hole；Back and forth washed by water to construction hole again；In construction hole site installation grout nipple；Sealed in cracks on floor slab surface smear
Chewing-gum；Grouter connection grout nipple carries out pouring into cement mortar.
In above-mentioned technical proposal, before cracks on floor slab drills through construction hole, first cracks on floor slab is dug into V-groove, ensures grouting
Stability.
In above-mentioned technical proposal, construction hole drill fetch bit is setting at the wider place, staggered place, end of cracks on floor slab or running through
Place, to ensure to reduce to cracks on floor slab destruction and ensure consolidation effect.
In above-mentioned technical proposal, every cracks on floor slab is at least provided with two construction holes, to install grout nipple and be used as exhaust.
In above-mentioned technical proposal, the spacing in hole of constructing ensure that the density in construction hole, grouting effect between 35cm-40cm
Fruit is more preferable.
In above-mentioned technical proposal, the width of sealing compound ensures that the sealing of sealing compound is imitated relative to the wide 1-3cm of cracks on floor slab
Fruit.
In above-mentioned technical proposal, the grouting pressure that grouter connection grout nipple is in the milk is gradually risen by low, to ensure
The stability of grouting.
In above-mentioned technical proposal, the grouting pressure that grouter connection grout nipple is in the milk is 0.2 to 0.4Mpa, ensures to fill
Starch effect and cracks on floor slab structure will not be deteriorated simultaneously.
In above-mentioned technical proposal, when grout nipple is in the milk, when the midge rate of grouter is less than 0.1L/ minutes, then
Constant pressure stops slip casting after grouting 3-8 minutes, ensure filling full water mud.
In above-mentioned technical proposal, after the completion of grouter grouting, grout nipple is blocked；Again after cement slurry sets, it will be in the milk
Mouth takes out, and is filled and led up with sealing compound at grouting, seals the cracks on floor slab after reinforcing.
The beneficial effects of the invention are as follows：This kind of Cracks On Concrete Floors reinforcement process, back and forth wash by water, can remove to construction hole
Impurity in cracks on floor slab, the cement mortar in grouting is set to be sufficient filling with and not influence cement mortar structure, and moisture content moistening floor
Behind crack, cement mortar and cracks on floor slab combine more preferably, and consolidation effect is more preferably.
Embodiment
A kind of Cracks On Concrete Floors reinforcement process, its step include:
First to clearing away impurity at cracks on floor slab, the impurity generally refers to unconsolidated formation existing for cracks on floor slab, dust dirt
Etc.；Surface concrete is cut to cracks on floor slab, until cracks on floor slab exposes solid internal layer, and by cracks on floor slab chisel into V-groove,
Ensure the stability of grouting；
Construction hole is drilled through in cracks on floor slab；Construct hole drill fetch bit setting at the wider place, staggered place, end of cracks on floor slab or
Through part, to ensure to reduce to cracks on floor slab destruction and ensure consolidation effect；The spacing in construction hole is protected between 35cm-40cm
The density in construction hole is demonstrate,proved, grouting effect is more preferable；Every cracks on floor slab is at least provided with two construction holes, to install grout nipple and work
For exhaust；
It is put into high-pressure water pipe to construction hole again back and forth wash by water to construction hole, the delivery port of high-pressure water pipe is in water pipe main body
Side, do not stop rotatably to wash away the hole wall in hole of constructing, and ceaselessly change high-pressure water pipe up and down in construction hole
Depth position, the silt in construct hole and crack is cleared up and prevents sediment deposition；
In the bottom spreading glue of grout nipple base, grout nipple is pasted on construction hole, with the installation grouting of construction hole
Mouth；And the centre bore of grout nipple need to be directed at crack, glue is avoided to block the slurry hole of grout nipple；
In cracks on floor slab surface smear sealing compound, the width of sealing compound ensures sealing compound relative to the wide 1-3cm of cracks on floor slab
Sealing effectiveness；After adhesive curing, cracks on floor slab is sprayed into from grout nipple with air gun, to examine cracks on floor slab insertion situation and sealing
The sealing situation of glue；
Grouter connection grout nipple carries out pouring into cement mortar；The grouting pressure that grouter connection grout nipple is in the milk is by low
Gradually rise, to ensure the stability of grouting；The grouting pressure that grouter connection grout nipple is in the milk is 0.2 to 0.4Mpa,
Ensure grouting effect and cracks on floor slab structure will not be deteriorated simultaneously；When grout nipple is in the milk, when the midge rate of grouter is small
When 0.1L/ minutes, then stop slip casting after constant pressure grouting 3-8 minutes, ensure filling full water mud.
After the completion of grouter grouting, grout nipple is blocked；Again after cement slurry sets, grout nipple is taken out, uses sealing compound
Fill and lead up at grouting, seal the cracks on floor slab after reinforcing.
Embodiment above is merely illustrative and not limiting to the invention, therefore all according to described in present patent application scope
The equivalent change or modification done of method, be included in the range of present patent application.
