Crack pouring treating method for crack of construction

Abstract

The invention discloses a crack pouring processing method for a building structure crack. The method comprises processing the crack base plane, installating an injection seat, sealing the surface of the crack, injecting crack pouring sealant, hardening maintenance and shaping and leveling. The method is characterized in that firstly scotch tapes are adopted to seal the crack surface, and two 5 to 8 cm of blank spaces without scotch tapes are reserved on the both sides of the injection seat along the crack direction, then transparent joint sealant is used to seal the crack surface (the parts adhered with scotch tapes are included), the sealing width is 4 to 6 cm, the sealed cross section of the transparent joint sealant on the crack surface is in arc, and the middle part is slightly thicker; empty injection seats without injectors are reserved among three to five injection seats as exhaust passages; red pigment is mixed in the joint sealant. The method has the advantages that the method is scientific and simple, the implementation is convenient and easy, the cost is low, the self-checking is convenient for the constructer, the full degree and the length of the crack pouring can be accurately confirmed, and the supervision and the acceptance of the construction are convenient, thus the crack pouring quality is guaranteed, simultaneously, the measurement control is convenient, and the construction cost is saved.

Description

technical field [0001] The invention relates to a method for treating cracks in building structures, especially a method for treating cracks. Background technique [0002] At present, the joint filling process used in the treatment of cracks in bridges and other building structures mainly includes the following steps: (1) Surface treatment: use a grinder to smooth the 1.5-2cm places along both sides of the crack, and then use a wire brush, steel wire Clean the dust, scum, loose layer and other dirt on the surface of the crack with common tools such as a wheel until the solid surface is exposed, then use a brush dipped in acetone, alcohol and other organic solutions, wipe clean along the surface of the crack on both sides and keep it clean. Dry; (2) Install the injection seat: install the injection seat along the crack, generally at a position of 30cm, the injection seat should be installed firmly, and completely sealed until the slurry does not leak, and the center of the in...

Problems solved by technology

For the cracks of the structure treated by the existing crack filling method, only the sealant can be seen on the surface, but it is impossible to directly check and understand the crack filling situation. It is necessary to check the filling effect after the sealant is removed, and sometimes the sealant is completely damaged. The gap embedded in the surface of the crack makes it impossible to see the traces of the sealant, and sometimes the sealant is not poured into the crack at all

Not only the quality of joint filling treatment cannot be guaranteed, but also brings difficulties to measurement management
