Description
Technical field
The present invention relates to a kind of grouting mending device of concrete defect, especially a kind of wet grouting mending for seeping concrete
Device further includes a kind of grouting mending method based on the wet grouting mending device for seeping concrete.
Background technique
In the construction of concrete for hydraulic structure, sometimes because of aggregate separated, owed to shake, leakage, spillage or because stone is maked somebody a mere figurehead in reinforcing bar
On skeleton, concrete leakiness, even internal formation honeycomb or cavity are easily led to.The presence of this defect often make structure or
Then there is leakage phenomenon in the total bearing capacity degradation of component, the building paddled.Such as pond, aqueduct thin wall concrete knot
Structure, self waterproofing ability weakens significantly when there is uncompacted concrete, and it is inevitable that leakage occurs in concrete.
The previous impervious leakage-stopping for seeping concrete that dissipates for leakiness carries out chemical grouting and repairs frequently with handlance, mechanical pump
It mends, but effect is mostly not satisfactory.Analyzing its reason is mainly that chemical grout pours into the lazy weight for dissipating and seeping in concrete, is risen not
To ideal seepage preventing effect.And chemical grout groundwater increment is insufficient main reasons is that pulsed is in the milk and is held to scattered infiltration concrete
Caused by continuous grouting time is insufficient.When due to being in the milk using handlance or mechanical pump, construction personnel need long-time operation handlance or
Mechanical pump is guarded, and smaller due to dissipating plasma volume of the infiltration concrete within the unit time, the scattered concrete that seeps is easily caused not eat slurry
Illusion, and grouting is terminated ahead of time.
It is analyzed according to the internal structure of leakiness concrete, there are various to be connected for uncompacted inside concrete
Stomata, when the stomata that only these are connected sufficiently uses chemical grout to fill, just can guarantee to leakiness concrete
Qualification repairing.Due to having gas in the various stomata being connected of leakiness inside concrete, when being in the milk to it,
There is air-resistance phenomenon, filling rate can not be too urgent, preferably uses the grouting way of continuous and constant pressure, and grouting effect could be ideal.
