Fabricated profile steel enclosure system for existing foundation protection and construction method of fabricated profile steel enclosure system
The invention discloses an assembly type profile steel enclosure system for protecting an existing foundation and a construction method of the assembly type profile steel enclosure system. Comprising the steps that assembly type enclosure steel piles are driven into soil bodies on the air sides of the three faces of the existing foundation according to preset intervals and depths, and bottom consolidation is formed; assembling type back row anchor shaping steel piles are driven into the stable soil body on the non-free side of the existing foundation according to the preset interval and depth, and consolidation is formed; an assembly type section steel coupling beam is supported on the assembly type enclosure section steel pile on each side through an assembly type bracket; an assembly type section steel coupling beam is supported on the assembly type back row anchor shaping steel pile through an assembly type bracket; and the assembly type section steel coupling beams spanning the existing foundation are connected between the oppositely arranged assembly type section steel coupling beams. The supporting system is safe and reliable, the foundation pressure of the existing foundation outside the pit is converted into the internal force of the enclosure system, the deformation control capacity is high, and the existing foundation can be effectively protected. Prefabricated components are adopted, high-strength bolts are convenient and rapid to install, and all main components can be recycled and reused.
本发明公开一种用于既有基础保护的装配式型钢围护体系及其施工方法。包括：在既有基础三面临空侧土体内按预定间距和深度打入装配式围护型钢桩，形成底部固结；在既有基础的非临空侧的稳定土体中按预定间距和深度打入装配式后排锚定型钢桩，形成固结；每侧的装配式围护型钢桩上通过装配式牛腿支托有装配式型钢连梁；装配式后排锚定型钢桩上通过装配式牛腿支托有装配式型钢连梁；在相对设置有装配式型钢连梁之间连接设置有跨越既有基础的装配式型钢连梁。本发明支护体系安全可靠，将坑外既有基础基底压力转化为围护体系的内力，变形控制能力强，可有效保护既有基础。采用预制装配式构件，高强螺栓安装方便快速，各主要构件可循环重复使用。
