Raft foundation for preventing differential settlement of underground buried pipe and construction method
The invention discloses a raft foundation for preventing differential settlement of an underground buried pipe, and relates to the technical field of building construction. The foundation comprises powder spray piles, a geotextile, a mattress layer, an inverted filter, a raft and a buried pipe buttress; the geotextile, the mattress layer, the inverted filter and the raft are sequentially arrangedon the upper sides of the powder spray piles; the buried pipe buttress used for bearing a buried pipe is arranged on the upper side of the raft; the cross section of the raft is inverted U-shaped, andis formed through combination of three parts: side piers, domes and drainage holes; and the powder spray piles are located at the bottom of the raft, and symmetrically arranged below the side piers on the left and right sides of the raft. The invention further provides a construction method of the raft foundation for preventing the differential settlement of the underground buried pipe. Accordingto the raft foundation for preventing the differential settlement of the underground buried pipe provided by the invention, the common phenomenon that differential settlement easily occurs at a buried pipe is effectively restrained, the post-construction settlement at the buried pipe is greatly reduced, and the phenomena such as leakage, rupture and the like of the buried pipe due to the differential settlement frequently occurring at the buried pipe are effectively reduced.
本发明公开了一种防止埋管不均匀沉降的筏板基础，涉及建筑施工技术领域。所述基础包括：粉喷桩、土工布、褥垫层、反滤层、筏板以及埋管支墩；所述粉喷桩上侧依次布置有土工布、褥垫层、反滤层、筏板；所述筏板上侧布置有用于支承埋管的埋管支墩，所述筏板截面呈∩形，由边墩、穹顶和排水孔三部分组合而成；所述粉喷桩位于筏板底部，对称布置在筏板左右两侧边墩的下方。一种防止地下埋管不均匀沉降的筏板基础的施工方法。本发明使得常见的埋管处易发生不均匀沉降的现象得到有效遏制，埋管处的工后沉降大幅度减小，有效减小了因埋管处经常发生不均匀沉降而使埋管发生渗漏、破裂等现象。
