Novel universal construction joint waterproof making method

The invention discloses a novel universal construction joint waterproof making method. The novel universal construction joint waterproof making method comprises the following steps: mounting early poured section angle steel in early poured section reinforced concrete; pouring the early poured section reinforced concrete; mounting later poured section angle steel in later poured section reinforcedconcrete; pouring the later poured section reinforced concrete; arranging a connecting steel plate between the early poured section angle steel of the early poured section reinforced concrete and thelater poured section angle steel of the later poured section reinforced concrete to perform welding for proofing water. The novel universal construction joint waterproof making method disclosed by theinvention is good in water stop effect, clear in construction, easy to construct, and suitable for various types of engineering; later maintenance is facilitated; a mounting process is simple; a waterproof effect is good; the
