Abstract
The invention discloses a crack treatment used for a super-long concreter beam, comprising procedures such as crack treatment, glue-injection nozzle arrangement, glue injection and sealing, etc. The invention can excellently solve the existing cracks on the super-long concreter beam, and can overcome safety threats and repair the appearance of the concrete beam, and the process is easy and the construction is convenient. The invention is particularly suitable for the crack treatment of a crossbeam with a span of more than 13 meters and an area of 600 multiplied by 1100 with an ideal effect.
Description
Technical field:
The present invention relates to a kind of building cracks processing method.
Background technology:
The crack treatment of super-long structural concrete beam, never good for a long time treating method makes the attractive in appearance and safety of crack influence.
Summary of the invention:
The object of the present invention is to provide a kind of super-long structural concrete beam crack processing method that can effectively solve super-long structural concrete beam crack.
Technical solution of the present invention is:
A kind of super-long structural concrete beam crack processing method is characterized in that: comprise the following steps: successively
(1) crack treatment: with wire brush cleaning concrete beam crack place unconsolidated formation, dust, dust is purged totally, with acetone the crack is cleaned then with compressed air;
(2) adhesive pouring nozzle is set: wide place, staggered place, end place, crack through part in the crack are provided with adhesive pouring nozzle, and other positions, crack are provided with adhesive pouring nozzle at interval;
(3) injecting glue: adopt the CH-4A base joint grouting glue that the crack is poured into, injection pressure is 0.2～0.4MPa, when inhaling slurry rate≤0.1L/min, continues pressure injection 3 minutes again, finishes encapsulating;
(3) seal: when glue reaches initial set and do not outflow in the crack, pull down adhesive pouring nozzle, seal the adhesive pouring nozzle place is floating, polish flat with Angle polishing machine with epoxy mortar.
In the step (2), the spacing that other positions, crack are provided with adhesive pouring nozzle at interval is 20cm.
The crack that the fine solution super-long structural concrete beam of the present invention's energy exists overcomes potential safety hazard, and it is attractive in appearance to repair the concrete beam, and method is simple, easy construction.Especially span is reached the crack treatment of 600 * 1100 crossbeams more than 13 meters, have very good effect.
The invention will be further described below in conjunction with embodiment.
The specific embodiment:
A kind of super-long structural concrete beam crack processing method comprises the following steps: successively
(1) crack treatment: with wire brush cleaning concrete beam crack place unconsolidated formation, dust, dust is purged totally, with acetone the crack is cleaned then with compressed air;
(2) adhesive pouring nozzle is set: wide place, staggered place, end place, crack through part in the crack are provided with adhesive pouring nozzle, and other positions, crack are provided with adhesive pouring nozzle at interval;
(3) injecting glue: adopt the CH-4A base joint grouting glue that the crack is poured into, injection pressure is 0.2～0.4MPa, when inhaling slurry rate≤0.1L/min, continues pressure injection 3 minutes again, finishes encapsulating;
(3) seal: when glue reaches initial set and do not outflow in the crack, pull down adhesive pouring nozzle, seal the adhesive pouring nozzle place is floating, polish flat with Angle polishing machine with epoxy mortar.
In the step (2), the spacing that other positions, crack are provided with adhesive pouring nozzle at interval is 20cm.
