Self-waterproof structure with no seam and no outer-wrapping and construction method of self-waterproof structure
The invention discloses a self-waterproof structure with no seam and no outer-wrapping and a construction method of the self-waterproof structure. The self-waterproof structure comprises a soil layer,reinforced concrete is arranged on the soil layer, a brick blank film of a lower groove structure is arranged in the reinforced concrete, plaster layers are arranged on the two faces of the inner side and the top of the brick blank film, and the brick blank film is provided with a concrete cushion layer; the reinforced concrete is further provided with a prestressed steel strand, and the prestressed steel strand is wrapped by a corrugated pipe and is pre-buried, connected and fixed by tensioning end anchoring systems at the two ends; and the tensioning end anchoring systems comprise base plates and spiral ribs. The prestressed steel strand is additionally arranged in a bottom plate, prestress is applied through a prestress technology, cracks can be reduced or even avoided, and the self-waterproof capacity of the structure is effectively improved; the basement bottom plate becomes a seamless prestress concrete structure part through prestress application, and the construction procedures of the outer wrapping type waterproof roll and the waterproof protective layer of a bottom plate post-cast strip can be further eliminated, the construction period is greatly shortened, the cost isreduced, and the engineering quality is effectively improved.
本发明公开了一种不设缝免外包结构自防水结构及其施工方法，包括土层，在土层上设有钢筋混凝土，在钢筋混凝土中设有下凹槽结构的砖胎膜，砖胎膜内侧、顶部两个面设有抹灰层，砖胎膜设有一层混凝土垫层；在钢筋混凝土还设有预应力钢绞线，该预应力钢绞线通过波纹管包裹并通过两端的张拉端锚固系统预埋连接固定；所述张拉端锚固系统包括垫板和螺旋筋。本发明在底板中加设预应力钢绞线，利用预应力技术施加预应力，可减小甚至避免形成裂缝，有效提高结构自防水能力，通过施加预应力，使地下室底板成为无缝预应力混凝土结构构件，进一步地，可以免去底板后浇带外外包式防水卷材、防水保护层施工工序，大大地节省工期，降低成本，有效提高工程质量。
