Abstract
The utility model discloses a raft foundation facade waterproof protection layer construction structure. The concrete cushion layers are arranged in the bottom and top plane areas of the foundation pit, the ALC plate layers are arranged in the side vertical face areas of the foundation pit, and the waterproof layers are laid on the concrete cushion layers and the ALC plate layers. The fine aggregate concrete protection layer is laid on the waterproof layer and corresponds to the plane area of the foundation pit, and the extruded polystyrene board protection layer is laid on the waterproof layer and corresponds to the side vertical face area of the foundation pit. According to the raft foundation facade waterproof protection structure, the high-strength extruded polystyrene board is adopted as the facade waterproof protection layer to be directly laid, the outer side of the extruded polystyrene board protection layer is plastered, the requirements of raft foundation facade waterproof protection and convenient and rapid construction can be met, the problem that facade fine aggregate concrete is difficult to pour is solved, and compared with traditional facade fine aggregate concrete, the facade waterproof protection structure has the advantages of being simple in structure and convenient to use. The structure is convenient and simple to operate on the whole and high in construction efficiency.
