Description
Technical Field
The utility model belongs to the building engineering field specifically, relates to an assembled basement drainage structures of preventing.
Background
Large tracts of land basement cast in situ reinforced concrete bottom plate often because factors such as the discreteness of concrete material itself and concrete shrink lead to the appearance and the existence of small crack, under the groundwater pressure effect, some thin crack development can lead to appearing local infiltration point on the structure bottom plate after lining up. The common bottom plate surface layer in engineering is that a cast-in-place concrete surface layer is made on a structural bottom plate, a small amount of construction steel bars are arranged in the concrete surface layer, and the surface layer is constructed later than the bottom plate, so that a construction interface actually exists between the surface layer and the structural plate. When the structural bottom plate has a water seepage point, the seeped underground water can diffuse at the interface between the surface layer and the bottom plate under the action of pressure, and can seep out of the ground when meeting the crack of the surface layer, thereby influencing indoor use. From the angle of maintenance use, it has certain difficulty to discover that ground infiltration is directly effectively repaired, because the infiltration point of actual structure bottom plate often is not the infiltration position of surface course, need chisel out the surface course on a relatively large scale and just can find real infiltration position and carry out the slip casting and repair, this is made a change the normal use of repairing the process and is influenced the basement greatly.
