Anti-leakage method of corroded and perforated iron sheet gutter

Abstract

The invention discloses an anti-leakage method of a corroded and perforated iron sheet gutter, and belongs to the technical field of anti-leakage. The anti-leakage method of the corroded and perforated iron sheet gutter comprises the steps of base layer cleaning, gutter reinforcement, anti-seepage and anti-corrosion treatments on the inner and outer surfaces of the gutter, the base layer cleaningcomprises the steps of treatment measures such as cleaning dirt, floated rust, and end craters, the gutter reinforcement treatment is divided into separate fine holes and large-area perforation situations and repair measures thereof, and the inner surface treatment measure of the gutter is a cold bonding construction method with wall-to-wall carpeting SBS waterproofing coils. According to the anti-leakage method of the corroded and perforated iron sheet gutter, the SBS waterproofing coil material is used, the price is much lower than that of anticorrosive paints, the service life is long, theconstruction technology is simple, immediate work engagement is facilitated, the result is quick, working time is saved, the labor efficiency is improved, meanwhile quality of anticorrosion is more easily ensured, the problem that the construction period is delayed due to the unsatisfactory anticorrosion quality is eliminated, other hidden dangers that may be caused by the replacement of the gutter to a profiled steel plate on the roof can be avoided, and the replacement cost is lowered.

Description

technical field [0001] The invention relates to the technical field of anti-leakage, in particular to a method for anti-leakage after iron sheet gutters are corroded and perforated. Background technique [0002] The gutter refers to the concave part between the two crotches of the roof of the building. Roof drainage is divided into organized drainage and unorganized drainage. Organized drainage generally collects rainwater in the gutter and then drains it from the rainwater pipe. The ditch that collects rainwater is called It is a gutter, and the gutter is mostly made of white iron sheet or asbestos cement. [0003] There is also a history of the rise of steel structure workshops in our country. The waste gas and dust emitted by some production workshops all year round adhere to the iron gutter, accumulating over time, resulting in serious corrosion of the iron gutter, and different degrees of perforation in some places, which is harmful to production and personal safety.

[0003] There is also a history of the rise of steel structure workshops in our country. The waste gas and dust emitted by some production workshops all year round adhere to the iron gutter, accumulating over time, resulting in serious corrosion of the iron gutter, and different degrees of perforation in some places, which is harmful to production and personal safety. Cause hidden dangers, the existing solution to the perforation of the gutter, on the one hand, is to apply anti-corrosion paint on the outer surface of the gutter, but the price of the anti-corrosion paint is relatively high, and the operation process is cumbersome, and the construction period is long; on the other hand, it is to replace the roof gutter, but the gutter may cause other hidden dangers to the roof profiled steel plate during the replacement process, resulting in property or personal safety being affected
