Specific embodiment
Explanation is further described to the technical solution of the utility model below by specific embodiment.
Embodiment 1：
A kind of copper seal waterproof construction for mass concrete, as depicted in figs. 1 and 2, in mass concrete
The application example of lock chamber lock wall is poured, casting of concrete in mass need to will pour several independent segments of section point, including being set to two
It is adjacent to pour between section concrete and both ends pour the copper seal 1 that section concrete is connect with two respectively, between each copper seal 1
Overlap joint welding, red copper welding rod gas welding is used during welding.Gas welding should preheat, 400 DEG C to 500 DEG C of preheating temperature, horizontal copper sheet with
During vertical copper sheet connection, the lap of splice is not less than 70mm.In the two neighboring gap for pouring and being formed between section concrete and position
Cystosepiment 2 is filled in 1 both sides of copper seal, i.e., cystosepiment 2 is set between each independent section concrete, cystosepiment 2 is closed for polyethylene
Hole cystosepiment 2, the thickness of cystosepiment 2 is 2cm.By setting cystosepiment 2 that can effectively reduce casting of concrete in mass crack
It generates.After the completion of single hop concreting, cystosepiment stickfast is completed by adjacent segment concreting by cement nail.
The sealant layer 3 to connect with cystosepiment 2 is equipped in above-mentioned gap in concrete inner surface side, sealant layer 3 is double
Component polysulfide sealant well and concrete bonding, while can play the role of filleting sealing.
