Soft soil foundation cast-in-place pile splicing structure and construction method thereof
The invention relates to the technical field of pile foundation construction, in particular to a soft soil foundation cast-in-place pile splicing structure and a construction method thereof.The soft soil foundation cast-in-place pile splicing structure comprises an original reinforced concrete cast-in-place pile, a plurality of steel casings and a plurality of cement casings and further comprises lengthened pile body longitudinal bars, spiral stirrups and the like; excavating to a pile splicing part to lengthen a pile body steel bar, using a cement pile casing as a cast-in-place pile concrete template, backfilling a soil body between the steel pile casing and the cement pile casing, pouring pile body concrete, and hoisting away from the steel pile casing. According to the pile splicing structure for the cast-in-place piles of the soft soil foundation and the construction method, excavation of a large amount of soil bodies of the soft soil foundation can be reduced, construction space and personnel safety are guaranteed, and accurate positioning of the pile bodies and the vibrating and pouring quality of concrete can be guaranteed.
本发明涉及桩基础施工技术领域，具体是一种软土地基灌注桩接桩结构及其施工方法，包括原钢筋混凝土灌注桩、多个钢护筒和水泥护筒，还包括接长的桩身纵筋和螺旋箍筋等，在原灌注桩位置压入多个钢护筒作为护壁结构开挖筒内土体，开挖至接桩部位接长桩身钢筋，利用水泥护筒作为灌注桩混凝土模板，并在钢护筒与水泥护筒间回填土体，浇筑桩身混凝土后吊离钢护筒。本发明提供的软土地基灌注桩接桩结构及施工方法可减少软土地基大量土体开挖，保证施工空间和人员安全，并能保证桩身的定位准确及混凝土的振捣浇筑质量。
