| description | The utility model discloses a raft foundation maintenance structure which comprises a raft foundation and is characterized in that a plastic film, a first heat preservation layer, a second heat preservation layer and a waste formwork are sequentially arranged on the surface of the raft foundation from bottom to top, and the waste formwork is fixedly connected with the raft foundation; wherein theraft foundation is provided with a plurality of test axes, each test axis is provided with at least four monitoring point positions, each monitoring point position is vertically provided with at leastthree temperature sensors along the thickness direction of the raft foundation, and all the temperature sensors at the position are electrically connected with a thermodetector at the position through sensor leads. According to the maintenance structure, heat and moisture losses on the surface of concrete are effectively reduced, the temperature gradient is reduced, construction of the next structure can be conducted on t |
