Prestressed seamless terrace and construction method thereof
The invention relates to a prestressed seamless terrace and a construction method thereof, and is applied to the field of terrace construction. According to the key point of technical scheme of the prestressed seamless terrace, the prestressed seamless terrace comprises a concrete pouring surface layer, a steel bar layer, a corrugated pipe layer, a first PE film layer, a second PE film layer, a medium sand cushion layer, a gravel layer and a base layer sequentially arranged in the vertical direction, wherein an annular first waterproof coiled material is arranged on the end surface, away fromthe medium sand cushion layer, of the second PE film layer along the periphery, the inner edge of the first waterproof coiled material is filled with a fine sand layer, the upper end surface of the fine sand layer is flush with the upper end surface of the first waterproof coiled material, and the first waterproof coiled material and the fine sand layer are abutted between the first PE film layerand the second PE film layer. The prestressed seamless terrace has the technical effects that the first PE film layer and the second PE film layer are not prone to damage, and therefore the moisture-proof performance of the terrace is improved.
本发明涉及一种预应力无缝地坪及其施工方法，应用在地坪施工领域，其技术方案的要点是：包含沿竖直方向依次设置的混凝土浇筑面层、钢筋层、波纹管层、第一PE膜层、第二PE膜层、中砂垫层、碎石层和基层，所述第二PE膜层背离中砂垫层的端面上沿周缘设有环形的第一防水卷材，所述第一防水卷材的内缘填充有细砂层，所述细砂层的上端面与第一防水卷材的上端面齐平，所述第一防水卷材和细砂层被抵紧在第一PE膜层和第二PE膜层之间。本发明具有的技术效果是：第一PE膜层和第二PE膜层不易破损，从而提高了地坪的防潮性能。
