Description
Technical field
The utility model belongs to building waterproofing technique field, and in particular to a kind of concrete joint water stop structure.
Background technique
In civil engineering percolating water, detail structure position accounts for major part, especially concrete joint (construction joint, change
Shape seam) it is almost the leakage of ten seams nine.Due to the waterproof operating difficulties of the part, quality is difficult to ensure waterstop often occur and fix
Loosely, it phenomena such as position inaccuracy, stone concentrates too much on neighbouring waterstop or waterstop two sides concrete vibrating leakiness, causes
Waterproof is set to fail.Construction joint percolating water is all relatively common in the engineerings such as building, bridge, tunnel.
Currently used for concrete construction joint waterproof measure there are many kinds of, specifically include following several structures:
1) outer waterproof measure refers to outer patch waterstop, outer patch waterproof roll, outer painting water-repellent paint etc., and then blocks construction slit
At water sealing structure；
2) putty type water expandable waterstop or water-swelling rubber water bar are laid on construction joint, make to stop by water filling
Construction joint is blocked in water bar expansion；
3) buried water stop (steel plate or rubber) or built-in slip casting pipe in using in construction joint are usually sent out in construction joint
When raw percolating water, pass through the direct slip casting of built-in slip casting pipe.Built-in slip casting pipe refers to that construction is directed toward in pre-buried inclination in construction joint two sides
The Grouting Pipe of seam when waterproof homework, injects grout material to construction joint by Grouting Pipe, spread it at construction joint simultaneously and coagulation
