Cast-in-place pile construction technology
The invention belongs to the technical field of cast-in-place pile construction, and discloses a cast-in-place pile construction technology which is accurate in positioning compared with a traditional re-checking method through a pile center centering method and simple and practical in operation compared with positioning re-checking through an instrument, saves manpower, material resources and financial resources, reduces engineering cost, improves engineering construction quality and improves construction efficiency. Multiple purposes are achieved; meanwhile, a reinforcing hole is pre-drilled in the cast-in-place pile in advance through a method for reinforcing the bearing capacity of the cast-in-place pile, and a steel pipe with the depth of the hole is welded on site. When reinforcing construction is carried out, a pre-drilled hole is cleaned through high-pressure jet grouting of cement paste, then a steel pipe is hoisted through a tower crane, the steel pipe can be conveniently placed in the pre-drilled hole by adjusting a steel wire rope of an adjusting and transporting section, and finally secondary grouting is carried out in the hole of the steel pipe, so that the whole reinforcing work can be completed. The method not only has the advantages of being rapid in construction and convenient to install, but also can effectively improve the pile bearing capacity, effectively save the construction period and reduce the construction cost.
本发明属于灌注桩施工技术领域，公开了一种灌注桩施工工艺，本发明通过桩心对中方法与比传统的复核方法相比定位精确，而且与使用仪器定位复核相比，操作简单而实用，节约人力、物力和财力，降低工程成本，提高了工程施工质量，一举多得；同时，通过加强灌注桩承载力方法预先在灌注桩上预钻加强孔，并现场焊接孔深长度的钢管。在进行加强施工时，先对预钻孔用水泥浆高压旋喷清孔，然后将钢管通过塔式起重机吊起，并通过调节调运节钢丝绳，即可方便地将钢管安放于预钻孔内，最后在钢管孔内进行二次灌浆即可完成整个加强工作；不仅具有施工快捷迅速、安装方便的优点，而且能够有效地提高桩承载力，并能有效地节约工期、降低施工成本。
