Manufacturing and construction method of quicksand and mucky soil prefabricated cushion layer
The invention discloses a manufacturing and construction method of a quicksand and mucky soil prefabricated cushion layer, and belongs to the technical field of building foundation cushion layers. According to the technology, a prefabrication method is combined with an assembly type structure construction technology, and the prefabricated cushion layer is formed in a one-time pouring mode; and the safety is good. According to the technology, a prefabrication method is adopted, concrete guide walls are manufactured at the positions of masonry brick moulding beds on the two sides of a cushion layer in advance, and therefore casualties caused by foundation pit collapse are avoided; the operability is good. According to the process, the pre-embedded hanging rings are reserved in the prefabricated concrete cushion, hoisting is convenient, use on the construction site is flexible, and good operability is achieved; the strength is high. According to the technology and construction, steel bars are arranged in the prefabricated cushion layer, the concrete strength is improved, the concrete surface adopts a secondary surface finishing technology, the overall strength is higher than that of a traditional cast-in-place cushion layer, the anti-cracking performance is good, and construction of the next working procedure (brick moulding bed masonry and waterproof roll paving) is facilitated.
本发明公开了流沙及淤泥质土预制垫层制作及其施工工法，属于建筑基础垫层技术领域，本工艺通过预制的方法，与装配式结构施工工艺相结合，预制垫层一次浇筑成型；安全性好。本工艺采用预制的方法，将垫层两侧砌筑砖胎模位置预先制作混凝土导墙，从而避免因基坑坍塌造成的人员伤亡；可操作性好。本工艺预制混凝土垫层留置预埋吊环，吊装方便，施工现场使用灵活，具有良好的可操作性；强度高。本工艺与施工时预制垫层内配置钢筋，混凝土强度有所提高，混凝土表面采用二次收面工艺，整体强度较传统现浇垫层高，抗裂性能好，有利于下道工序(砖胎模砌筑、防水卷材铺贴)的施工。
