Construction method of slurry retaining wall pore-forming cast-in-place pile
The invention discloses a slurry retaining wall pore-forming cast-in-place pile construction method. The method comprises the following steps that firstly, construction preparation is conducted; secondly, a steel protection cylinder is machined and manufactured, then the protection cylinder is buried according to the pile site, and the space between the protection cylinder and the pit wall is filled with filling soil; thirdly, a slurry circulation system is arranged; fourthly, pile foundation hole forming is conducted; 5, conducting conduit splicing and pressure testing; wherein the pile foundation quality detection in the step 5 comprises the step of carrying out pile body quality detection by adopting a core drilling sampling test and a low-strain or sound wave transmission method. According to the construction method of the slurry retaining wall pore-forming cast-in-place pile, through the arrangement of the step 5, the quality detection of the pile foundation can be effectively achieved, and the quality detection of the pile body is achieved.
本发明公开了一种泥浆护壁成孔灌注桩施工方法，包括如下步骤：步骤一，进行施工准备；步骤二，加工制作钢护筒，之后根据桩位点埋设护筒，将护筒与坑壁之间用填土填实；步骤三，布设泥浆循环系统；步骤四，桩基成孔；步骤五，进行导管拼接和试压；其中，步骤五中的桩基质量检测包括采用钻芯取样测试、低应变或声波透射法进行桩身质量检验。本发明的泥浆护壁成孔灌注桩施工方法，通过步骤五的设置，便可有效的实现桩基质量检测，实现对于桩身质量的检测了。
