Shallow foundation building reinforcement protection construction method and structure thereof
The invention discloses a reinforcing and protecting construction method and structure for a shallow foundation building, and the reinforcing and protecting construction method for the shallow foundation building comprises the following steps: grouting and reinforcing a ground sleeve valve pipe; before foundation pit construction, upper sleeve valve pipes with the diameter phi being 42 and t being 3.5 mm are adopted between a foundation pit and a building 1 to conduct oblique punching and grouting, the grouting interval is 300 * 300 mm, the upper sleeve valve pipes are arranged in a quincunx shape, and the punching and grouting depth is determined according to the geological condition; a bottom sleeve valve pipe grouting reinforcement procedure; after grouting reinforcement of the upper sleeve valve pipe is completed, excavation construction of the foundation pit is carried out, and punching grouting reinforcement is carried out on a soil body below the shallow foundation building horizontally adjacent to the interior of the foundation pit; a lower sleeve valve pipe with the diameter phi being 42 and the t being 3.5 mm is adopted for punching and grouting, the horizontal grouting interval is determined by combining the interval of the foundation pit support structure, and the vertical grouting interval is preferably 500 mm; the punching depth and range are determined according to the projection area of the shallow foundation building, and the lower sleeve valve pipes are arranged in the whole range of a projection plane and exceed 2 m in each direction.
本发明公开一种浅基础建筑物加固保护施工方法及其结构，其中，一种浅基础建筑物加固保护施工方法，包括以下步骤：地面袖阀管注浆加固工序；在基坑施工前在基坑与建筑物1之间采用Φ42，t＝3.5mm上袖阀管斜向打孔注浆，注浆间距宜为300×300mm，按梅花形布置上袖阀管，打孔注浆深度根据地质情况确定；底部袖阀管注浆加固工序；在上袖阀管注浆加固完成后，进行基坑开挖施工，在基坑内部水平向紧临的浅基础建筑物下方土体进行打孔注浆加固；采用Φ42，t＝3.5mm的下袖阀管打孔注浆，水平向注浆间距结合基坑围护结构的间距而定，垂直向注浆间距宜为500mm；打孔深度以及范围根据浅基础建筑物的投影面积而定，在投影面全部范围内布置下袖阀管且每个方向各超出2m。
