Description
Technical field
The utility model belongs to basement post-pouring zone part leakage maintenance technique field, and in particular to one kind being used for basement
Structure is repaired in the leak at post-cast strip position.
Background technology
With the continuous improvement of the sustainable development and people's lives of society, pursuit of the people to living conditions and environmental quality
Also it improves increasingly, this also proposes requirements at the higher level to the normal usage function of building.Significant points underground as building
Room, also more and more common in current architectural design, but the leakage problems of basement are high, especially basement post-pouring zone
The leakage of junction becomes one leakage keypoint part of basement, and detrimental effect is caused to the normal use of basement.
Currently, after underground space post-cast strip position leaks, the repair mostly based on grouting for water plugging, supplemented by water-repellent paint
Method.The effects that its principle is the infiltration of itself, the foaming and intumescing by injecting paste material blocks up the micro-cracks of concrete itself,
Play the role of impervious leakage-stopping.Its drawback has：1. grouting for water plugging is mostly with the slip casting in the case where wall body slit has bright water, effect is most
It is good.And encountering when actually slip casting is repaired has the condition in the wall leakage crack of bright water to be relatively difficult to reach.2. encountering more multiple
Miscellaneous structure wall crack, often once grouting leak stopping do not live, and need 2-3 slip casting, can just play due effect.
The utility model patent of Patent No. ZL 201720021325.7 discloses a kind of underground connection wall seaming position
Water sealing structure, including after the leading width diaphragm wall of seam and after row width diaphragm wall, in leading width diaphragm wall and rear row width diaphragm wall
It includes the end socket muscle of the diaphragm wall main reinforcement and seam crossing of vertical setting that bundle, which has steel reinforcement cage, steel reinforcement cage, it is characterised in that：In leading width
The inside top vertical of diaphragm wall end socket muscle is arranged and the isometric slip casting steel pipe of diaphragm wall main reinforcement, quincunx in slip casting steel pipe wall
Arrange injected hole.
