Deep foundation pit combined supporting system capable of eliminating influence on existing building and construction method of deep foundation pit combined supporting system
The invention relates to the field of building construction, in particular to a deep foundation pit combined supporting system eliminating influences on an existing building and a construction method of the deep foundation pit combined supporting system. The deep foundation pit is close to an existing building and comprises a first supporting structure, a second supporting structure and a third supporting structure. The first supporting structure comprises a sleeve valve pipe grouting area, a triple-pipe high-pressure jet grouting pile waterproof curtain and a plurality of rotary excavating cast-in-situ bored piles. The second supporting structure comprises a plurality of three-axis cement mixing piles; the third supporting structure comprises a plurality of concrete inner supports and a plurality of steel pipe inclined supports, the concrete inner supports and the steel pipe inclined supports are connected with the rotary excavating cast-in-situ bored piles correspondingly, and the bearing force of the rotary excavating cast-in-situ bored piles is dispersed through the concrete inner supports and the steel pipe inclined supports. Through reasonable matching of the three supporting structures, the supporting strength of the deep foundation pit supporting structure is improved while safe use of an adjacent existing building is guaranteed, and the safety risk generated to the adjacent existing building in the deep foundation pit construction process is reduced.
本发明涉及建筑施工领域，是一种排除对现有建筑影响的深基坑组合支护体系及其施工方法。深基坑紧邻现有建筑，包括第一道支护结构、第二道支护结构和第三道支护结构；第一道支护结构包括袖阀管注浆区、三重管高压旋喷桩止水帷幕和若干旋挖钻孔灌注桩；第二道支护结构包括若干三轴水泥土搅拌桩；第三道支护结构包括若干混凝土内支撑和若干钢管斜支撑，若干混凝土内支撑和若干钢管斜支撑分别与若干旋挖钻孔灌注桩相连接，通过若干混凝土内支撑和若干钢管斜支撑将若干旋挖钻孔灌注桩的承重力分散。通过三道支护结构合理搭配，在保障紧邻现有建筑安全使用的同时，提高深基坑支护结构的支护强度，降低深基坑施工过程对紧邻现有建筑产生的安全风险。
