Miniature steel pipe pile for reinforcing foundation and construction method thereof
The invention provides a miniature steel pipe pile for reinforcing a foundation and a construction method thereof, the miniature steel pipe pile comprises a plurality of spliced pipe bodies, and at least two grouting pipes are further arranged in the pipe bodies and used for grouting the pipe bodies; a pile head is arranged at one end of the pipe body, a grout stopping section and a grouting section are sequentially arranged on the side, away from the pile head, of the pipe body, no hole is formed in the grout stopping section, and a grouting hole is formed in the grouting section and used for grouting reinforcement. The method has the beneficial effects that the micro steel pipe piles can be flexibly arranged according to the distribution condition of the karst cave of the foundation, reinforcement is targeted, and accurate reinforcement is achieved; the miniature steel pipe pile foundation reinforcement technology adopts finished small-diameter steel pipes for grouting reinforcement treatment of a foundation karst cave, and is simple in structure, clear in process, convenient to construct and easy in quality control; a high-strain detection method is adopted for detecting the bearing capacity of the miniature steel pipe pile, detection shows that the bearing capacity of the miniature steel pipe pile is high in compression bearing capacity and good in reinforcing effect, and the bearing capacity of the platform ring beam foundation is comprehensively improved.
本发明提供一种加固地基基础的微型钢管桩及其施工方法，包括：多个拼接设置的管体，所述管体内还设置有至少两个注浆管，用于向所述管体内注浆；所述管体的一端设置有桩头，所述管体远离所述桩头的一侧依次设置有止浆段和注浆段，所述止浆段不开设孔，所述注浆段开设有注浆孔，用于注浆加固。本发明的有益效果是微型钢管桩根据地基溶洞分布情况可灵活布置，加固具有针对性，做到精准加固；微型钢管桩地基加固技术采用成品小直径钢管注浆加固处理地基溶洞，结构简单，工序明确，施工方便，质量易控制；采用高应变检测法对微型钢管桩承载力进行检测，检测表明微型钢管桩承载力的抗压承载力强，加固效果好，综合提高平台环梁基础承载力。
