Description
Technical field
The present invention relates to concrete field more particularly to a kind of concrete structure longitudinal crack method for repairing and mending.
Background technique
It is also easy to produce crack in concrete construction use process at present, if generated crack in hardening process, in use process
Probably due to the reasons such as concrete shrinkage, sedimentation, temperature difference generate crack, the performance of building is influenced；Especially Structural Engineering,
It will appear different form in construction and use process, different degrees of crack, this not only influences the appearance of building, more jeopardizes building
Normal use and structure durability.When generating crack in reinforced concrete structures, it may appear that drainage, when no water source
Also the moisture attack contained by air due to cause steel bar corrosion and cement neutralisation, and then shorten building service life, because
This crack problem is paid close attention to by people.In existing crack repairing processing technique, general injector slip casting method is difficult to control institute
The amount of slurries is needed, cannot be filled up compared with large fracture, and pressure is low, the impermeable gap depths of slurries is unable to fracture and carries out effectively
Repairing；High-Pressure Grouting Method needs to drill in structure, slot, and destroys former concrete original structure, influences the performance of concrete structure,
Influence sight.
Summary of the invention
Purpose of the invention is to overcome the shortcomings in the prior art, provides a kind of easy to operate, controllable filler
The Xtah Crude Clay structure part longitudinal crack method for repairing and mending of amount.
To achieve the above object, the present invention uses following technical scheme：
A kind of concrete structure longitudinal crack method for repairing and mending includes following when repairing to concrete structure longitudinal crack
Implementation steps：
Crack chisels is gone out V-type or U-shaped, with hair dryer counterincision sealing and concrete structure surface by step 1, cleaning crack mouthful
It is cleared up；
Step 2 pastes glue injection machine, the plastic hole of glue injection machine is aligned with crack, and successively interval is viscous from bottom to up in crack along longitudinal direction
Paste glue injection machine；Glue injection machine is followed successively by the 1st glue injection machine, the 2nd glue injection machine ... N glue injection machine from the bottom to top；
Joint seal glue is uniformly applied to crack Kou Chu by step 3, dead-end fracture；
Step 4 checks sealing situation, fills the water into the 1st glue injection machine, if water is infused from the 2nd glue injection machine, the 3rd glue injection machine ... N
The outflow of glue device, then seal it is intact, it is on the contrary then need repeatedly step 3 and step 4；
Step 5, modulation filling glue, after crack internal water is dry, modulation filling glue；
The gum-injecting port of glue-injection machine connect with the 1st glue injection machine, gradually pressurizes by step 6, injecting glue, to filling out for the 2nd glue injection machine outflow
When filling glue bubble-free, close the 2nd glue injection machine and the 1st glue injection machine, the gum-injecting port of glue-injection machine connect with the 3rd glue injection machine, gradually plus
Pressure closes the 4th glue injection machine, using the sequence of above-mentioned one glue injection machine in interval when the filling glue bubble-free of the 4th glue injection machine outflow
Injecting glue upwards in turn, until injecting glue finishes.
Preferably, the spacing in the step 2 between adjacent glue injection machine is between 15cm -20cm.It is filled out needed for control
The amount for filling agent guarantees to fill up crack.
Preferably, needing certain time dry after joint seal glue is smeared in the step 3.Give joint seal glue certain strong
Degree, prevents when carrying out step 4, and joint seal glue is broken through in water filling.
Preferably, filling glue domestic demand in the step 5 is added waterproof resin.Reinforce the waterproof effect in crack, increase is built
The service life built.
Preferably, the step 6 further includes recycling the filler of glue injection machine outflow.After filler flows out glue injection machine,
It is recycled, it can material saving.
Preferably, the pressurization pressure of the step 6 glue-injection machine is between 0.2-0.6MPa.Prevent pressure is excessive from breaking through
Joint seal glue.
Preferably, further including step 7 after the step 6, polish concrete structure fracture faces.
Beneficial effects of the present invention：（1）Filler is pressurized to gap depths by the amount that can control required filler；（2）
It is easy to operate, it is easy to construct.
Detailed description of the invention
Fig. 1 is process flow chart of the invention.
Specific embodiment
The principle of the present invention is further described in the following with reference to the drawings and specific embodiments：
A kind of concrete structure longitudinal crack method for repairing and mending includes following when repairing to concrete structure longitudinal crack
Implementation steps：
Crack chisels is gone out V-type or U-shaped, with hair dryer counterincision sealing and concrete structure surface by step 1, cleaning crack mouthful
It is cleared up；
Step 2 pastes glue injection machine, the plastic hole of glue injection machine is aligned with crack, and successively interval is viscous from bottom to up in crack along longitudinal direction
Paste glue injection machine；Glue injection machine is followed successively by the 1st glue injection machine, the 2nd glue injection machine ... N glue injection machine from the bottom to top；
Joint seal glue is uniformly applied to crack Kou Chu by step 3, dead-end fracture；
Step 4 checks sealing situation, fills the water into the 1st glue injection machine, if water is infused from the 2nd glue injection machine, the 3rd glue injection machine ... N
The outflow of glue device, then seal it is intact, it is on the contrary then need repeatedly step 3 and step 4；
Step 5, modulation filling glue, after crack internal water is dry, modulation filling glue；
The gum-injecting port of glue-injection machine connect with the 1st glue injection machine, gradually pressurizes by step 6, injecting glue, to filling out for the 2nd glue injection machine outflow
When filling glue bubble-free, close the 2nd glue injection machine and the 1st glue injection machine, the gum-injecting port of glue-injection machine connect with the 3rd glue injection machine, gradually plus
