Abstract

The invention relates to a high-side wall concrete construction joint zero-defect construction method. A poured bin side joint is polished to be flat, circumferential cutting is carried out at the side joint to form a construction joint, the construction joint and a grinding area are cleaned, a double-faced adhesive tape is attached to the flat grinding area. before pouring of a to-be-poured bin,a trolley template, the cutting joint and the double-faced adhesive tape are pressed and sealed, the trolley template is controlled to compress the thickness of the double-faced adhesive tape, and therefore the trolley template and the poured bin side joint are closely attached without seam face fracturing. The high-side wall concrete construction joint zero-defect construction method overcomes the problems that the joint angle of an original high side wall lining construction joint has defects, lap joint sealing is not good, and the lap joint opportunity selection deviation has defects, and the beneficial effects that the lap joint is tight, the joint angle of the construction joint is free from defects, jointing and sealing are good, during pouring of the to-be-poured bin, fracturing ofthe side joint is not prone to generating, slurry seepage is not prone to happening, and operation is simple and convenient to achieve are achieved.

Description

technical field

[0001] The invention belongs to the technical field of construction and relates to a defect-free construction method for high side wall concrete construction joints. Background technique

[0002] The existing high-side wall lining concrete construction technology does not completely solve the defects of the construction joints. In terms of solving the defects of the construction joints, it mainly relies on the setting of lap plates, and does not consider the advance treatment of the construction joints of the poured concrete. Defects in the construction joints are likely to cause larger defects in the later construction joints, and no clear fine-grained cleaning requirements have been put forward for the foreign objects intruded into the construction joints in the warehouse. If the timing is wrong, it is easy to cause fracturing of the construction joint surface of the poured concrete. Contents of the invention
