Description

Overhauling buried deformation joint structure with dewatering hidden ditch

Technical Field

The invention relates to a building structure, in particular to an overhauling buried deformation joint structure with a dewatering blind ditch.

Background

With the development of the times and the economic progress, the large-scale composite function buildings are more and more, the building body combination is more and more complex, and the combination of large chassis overhead layers or skirt houses and a plurality of tower buildings is more. In order to make the structure stress reasonable, the structure usually considers to be provided with through deformation joints around the tower and on the overhead floor top plate or the skirt house surface. Under the concept of modern ecological green buildings, the roof and the skirt house surfaces are usually important areas for landscape greening, the thickness of common full-area covering soil is between 1.2m and 1.5m, and the periphery of a tower is often the necessary path for a large number of equipment pipeline exit pipes to enter outdoor sites.

In general, in order to reduce water leakage at the deformation joint, the deformation joint structure of the planting top plate is to set up a back ridge higher than the surface of planting soil at both sides of the deformation joint, and then to perform the deformation joint plugging structure at the top of the back ridge. The mode of protruding the ground greatly influences landscape design, and when the deformation joint is positioned around the tower, the deformation joint is higher than the ground and can also obstruct the equipment pipeline exit pipe. If the deformation joint structure is considered to move downwards to ensure the integrity of the upper ground, the deformation joint needs to be arranged in the soil carrying moisture. In recent years, sponge cities advocate site water conservation, the water content in the soil is more, deformation joints are placed in the soil for a long time, and leakage is easy to occur under the conditions of soil pressure and water erosion. And the deformation joint is buried in the soil, so that the deformation joint cannot be maintained daily and cannot be overhauled conveniently after leakage occurs.
