Abstract
A water-proofing repair method for joint of fabricated external wall includes cleaning leakaging cavity with high-pressure air and water, blocking and smoothing the internal and external seams of the acvity with dry hardening water-proof mortar, embedding pouring tube, pressure pouring of water-proof mortar prepared from cement, sand and water-proofing agent FS-G with 0.4 MPa of pressure, blocking and pressing the pour hole with dry hardening mortar, and brushing water-proof paint. Its advantages include high anti-leakage performance, and creation of prestressing to prevent generation of crack.
Description
The invention belongs to the seam construction of house precast wall panel, relate to a kind of water-proof repairing method of mounting outer wall slab crack.
The inner deposited and outer hung system of high residential building, employing be the assembling out-hung panel, transverse joint between the wallboard and perps are provided with the cavity waterproof.Promptly keep one section cavity, make waterproofing course with polyvinyl chloride plastic flitch and malthoid, outside plastics sealing rod, waterproofing mortar sealing in the inboard of cavity at the wallboard seam crossing.This weather check method though use generally, has deviation as plate seam width in the construction, just is difficult to play the sealing effect; Be concealed work, be difficult for during examination finding that As time goes on, these materials are aging gradually, lose the sealing function, cause and leak again.Possessing leakage cause is: during the wallboard lifting, transverse joint, perps have certain deviation, and the width of sealing rod is difficult to hold, and puts in the water stopping trough tight inadequately; Transverse joint is sat slurry, when the wallboard hoisting alignment, seldom makes slurry full; The keyway on wallboard top, at transportation, hoisting process, damaged in collision is more, loses waterproof action; Because temperature Change, cause that the plate seam creeps, ftractures, moisture immerses, and sealing rod is ineffective; The cavity of each wallboard is interconnected, and adjutage inserted dark or blocked, and the plate seam leaks and can not in time discharge, and will cause interior wall many places seepage.
The objective of the invention is, prepare a kind of new waterproof mortar, adopt the pressure grouting method, in all cavitys with high pressure injection plate seam, tamp, to reach the thorough waterproof leak-stopping of side fascia seam.
Mounting outer wall slab crack water-proof repairing method of the present invention by cleaning cavity, is buried grout pipe underground, pressure grouting, plug-hole cleaning operation is formed, and it is characterized in that, adopt pressure-air and water, cleaning up in the cavity, stifled flat along the inside and outside seam of cavity with the dry waterproofing mortar; A grout pipe is put for 1 meter in every interval, and after maintenance in 24 hours, waterproofing mortar reaches certain intensity, begins grouting; The component of waterproofing mortar and ratio are: 425# cement: fine sand: FS-G high-effect water-proof agent=1: 1.5: 0.12; Grouting pressure 0.4MPa compresses into the cavity of wallboard to waterproofing mortar with air compressor machine by grout pipe, flows out slurries until adjoining eyelet and stops; , pressing stifled in fact grout hole with the dry waterproofing mortar; Plate seam brush waterproof paint.
Mounting outer wall slab crack water-proof repairing method of the present invention, when being used for building aging blocks, its method feature is, from the bottom up on the waterstop of the transverse joint of plate seam, perps, a grout hole is made a call to for 1 meter in every interval, beaten the grout hole of one deck unit area after, pressure grouting at once.
Mounting outer wall slab crack water-proof repairing method of the present invention, the component of its waterproofing mortar and ratio can be 425# cement: fine sand: FS-G high-effect water-proof agent=1: 0～2: 0.05～0.20; Grouting pressure can 0.2～0.6MPa.
Advantage of the present invention is, the FS-G high-effect water-proof agent that is adopted is the mixture of one kind of multiple organic materials and inorganic material, can in cement, produce the physical-chemical effect, can make cement in hydration process, form a large amount of expansion crystalline solid, stop up the capillary porosity, reduce the transmission coefficient of mortar, increase the anti-permeability performance of mortar self; Simultaneously, the crystalline solid that expands in a large number produces the expansion of appropriateness under the restriction between plate and the plate, can set up the compressive pre-stress of 0.2～0.7MPa in mortar, has avoided because the crack that drying shrinkage is crept and produced.The grouting pressure that is adopted is 0.2～0.6MPa, can realize that operation is easy with grouting equipments such as common air compressor machine, mortar pressurized tanks, and the work efficiency height can be used for new building waterproof homework or aging blocks mending-leakage operation; The plate seam waterproof waterstop that pressure grouting forms has certain toughness, the infinitesimal deflection of energy commensurate structure.The present invention is applicable to the water-proof repairing of assembling side fascia, box external wall seam.
Below in conjunction with drawings and Examples, the invention will be further described:
Fig. 1 is the process chart of mounting outer wall slab crack water-proof repairing method
As seen from the figure, before the construction, assemble plug-in elevator, after succeed in the test run, confirming the safety device no problem, the beginning operation.For new building, adopt pressure-air and water, cleaning up in the cavity, stifled flat along the inside and outside seam of cavity with the dry waterproofing mortar; A grout pipe is put for 1 meter in every interval, and after maintenance in 24 hours, waterproofing mortar reaches certain intensity, begins grouting; The component of waterproofing mortar and ratio are: 425# cement: fine sand: FS-O high-effect water-proof agent=1: 0～2: 0.05～0.20; Grouting pressure 0.2～0.6MPa compresses into the cavity of wallboard to waterproofing mortar with air compressor machine by grout pipe, flows out slurries until adjoining eyelet and stops; , pressing stifled in fact grout hole with the dry waterproofing mortar; Plate seam brush waterproof paint.
For aging blocks, on the waterstop of the transverse joint of plate seam, perps, a grout hole is made a call to for 1 meter in every interval from the bottom up, beaten the grout hole of one deck unit area after, pressure grouting at once.Plug-hole cleaning then, plate seam brush waterproof paint.
