Polyurethane and dense water glass mortar combined impervious ground construction method
The invention discloses a polyurethane and dense water glass mortar combined impervious ground construction method, which belongs to the technical field of ground construction, and comprises the following steps: (1) ramming plain soil with the compaction coefficient of more than or equal to 0.94%; (2) preparing C15 plain concrete with the thickness of 150mm; (3) a plastic film layer with the thickness of 0.2 mm is pasted and cleaned up; (4) C30 fine stone impervious concrete with the thickness of 170 mm is prepared, the impervious grade is not lower than P8, a bidirectional phi 6 at-200 anti-crack reinforcing mesh is arranged in the concrete, and 1: 1 cement sand is scattered on the surface to be polished while being beaten; (5) coating a polyurethane coating with the thickness of 1.5 mm; (6) a dense water glass mortar bonding layer with the thickness of 10-15 mm; and (7) the granite plate with the thickness of 40 mm is subjected to crack pouring with epoxy asphalt mortar, and the crack width is 8-15 mm. The C30 fine stone impermeable concrete is adopted, so that the compactness is higher, slurry extraction is easier in the polishing work, the working efficiency is improved, and the construction period is shortened; after the thickness is adjusted to 170mm, the polyurethane coating is directly constructed after polishing treatment, and the leveling function is undertaken by the dense water glass mortar bonding layer, so that the construction period is shortened, and the construction quality is ensured.
本发明公开了聚氨酯+密实水玻璃砂浆结合抗渗地面建造方法属于地面建造技术领域，包括如下步骤：(1)素土夯实，压实系数≥0.94%；(2)150mm厚C15素混凝土；(3)0.2mm厚塑料薄膜层粘贴，并清理干净；(4)170mm厚C30细石抗渗混凝土，抗渗等级不低于P8，内配双向Φ6@200抗裂钢筋网片，表面撒1：1水泥砂子随打随磨光；(5)1.5mm厚聚氨酯涂层；(6)10~15mm厚密实水玻璃砂浆结合层；(7)40mm厚花岗岩板用环氧沥青胶泥灌缝，缝宽8‑15mm。本发明采用C30细石抗渗混凝土密实度更高，磨光工作中提浆更为容易，提高了工作效率，缩短了工期；厚度调整到170mm后做磨光处理后直接施工聚氨酯涂层，找平功能由密实水玻璃砂浆结合层承担，缩短了施工工期，保证了施工质量。
