Method for reinforcing foundation through construction waste

ZHANG AIPING

The invention discloses a method for reinforcing a foundation through construction waste and relates to the technical field of construction. The method mainly comprises the following steps: S1, calcining and screening the construction waste to obtain construction waste slag powder; S2, soaking the construction waste slag powder in a nitric acid solution, and mixing the construction waste slag powder with stearic acid and plant ash to obtain activated slag powder; S3, mixing cement, sand, paint slag, silicon powder, bentonite, the activated slag powder and water to form a cement mixture; S4, drilling holes in the foundation to form hole columns; S5, pouring cement mortar into the hole columns; S6, vibrating and tamping to form concrete columns; and S7, laying a steel bar net rack on the surface of the concrete columns, pouring cement to form rectangular concrete blocks, and fixedly connecting the rectangular concrete blocks with the concrete columns to form an overall reinforced foundation. The treated construction waste is fully utilized as aggregate, the production cost is greatly reduced, meanwhile, the prepared construction waste cement has excellent mechanical strength, effective treatment of the construction waste can be achieved, the reinforcing cost is reduced, and the reinforcing effect is good.

一种利用建筑垃圾加固地基的方法，涉及施工技术领域。主要步骤如下：S1.将建筑垃圾煅烧、筛选后制得建筑垃圾渣粉；S2.将建筑垃圾渣粉经过硝酸溶液浸泡、与硬脂酸和草木灰混合后制得活化渣粉；S3.将水泥、砂、漆渣、硅粉、膨润土、活化渣粉和水混合而成水泥混合物；S4.在地基上钻孔，形成孔柱；S5.往孔柱灌注水泥砂浆；S6.振捣夯实，形成混凝土柱；S7.在混凝土柱表面铺设钢筋网架，并用水泥浇筑，形成矩形混凝土块，与混凝土柱连接固定，形成整体加固地基。本发明充分利用处理过的建筑垃圾作为骨料，极大地降低了生产成本，同时制得的建筑垃圾水泥具有优异的机械强度，能够实现建筑垃圾的有效处理，降低加固成本，加固效果好。
