Description
Technical Field
The invention relates to the technical field of seepage prevention of a communication port structure of a basement of a building, in particular to a communication port structure of the basement based on a water stop steel plate and a seepage prevention construction method.
Background
At present, most of the residential buildings are designed to be super high-rise houses with basements around or in front of the residential buildings, and the residential buildings are underground garages or underground civil air defense projects. The connected channel interfaces between them are called communication ports. The general waterproof structure of the communicating port is that the middle-set rubber waterstop is used for preventing the groundwater from infiltrating, and the outmost detachable rubber waterstop is used for preventing the water seepage caused by the construction or material defects of the middle-set waterstop. However, this construction method always causes water seepage, and the following reasons are found through case inspection and analysis on a plurality of sites: 1. the middle-set rubber water stop is pre-embedded when concrete is poured at the two connectors of the communicating port. The settlement of the house foundation downwards is caused by the dead weight of the super high-rise house, and is completed within several years. But not the underground garage or underground civil air defense engineering outside the house, under the action of the underground water level, the underground garage or underground civil air defense engineering is subjected to upward buoyancy. Therefore, concrete on two sides of the communication port sinks and floats, and the original embedded middle-mounted water stop belt is prone to aging due to the fact that the material quality is poor and the rubber water stop belt is prone to water seepage due to the fact that the rubber water stop belt is torn under the action of external force due to the fact that the middle-mounted water stop belt is prone to aging under the action of long-time underground water level. 2. The detachable water stop belt can be torn by external force. In addition, because it is removable, manual construction quality instability can cause water seepage if the compression plate is not compressed or the nut is not tightened. 3. The central water stop is a rubber product, has smooth surface and adhesion with concrete, and can cause water seepage due to gaps between concrete and the water stop caused by thermal expansion, cold contraction and aging.
Therefore, basement intercommunication mouth seepage is a phenomenon that the building trade ubiquitous, specifically for if meet reasons such as building material shrinkage is big, subside and lead to the intercommunication mouth to produce the crack and take place the seepage, if meet when the gap that produces is great, adopt the mode effect of present ordinary leaking stoppage king-adding chemical grouting not very good, can not avoid taking place the seepage completely.
