Construction method for PHC pipe pile close to factory building
The invention discloses a construction method for PHC pipe piles close to a plant. The method comprises the steps that a built plant serves as an original point, a pile to be driven is marked within the area range which is 1.5 times of the length of an original pile of the plant, and the pile to be driven is drilled according to the mode that the pile to be driven and the original pile are jumped one by one; the depth of the guide hole is 2/3 of the length of the pile; after hole guiding is completed, the construction speed of new piles in the pile foundation range of the three rows of original piles is slowed down to 1/2 times with the built plant as the original point; and after construction is completed, construction of other non-influence areas is started. According to the construction method of the PHC pipe pile close to the factory building, the soil squeezing effect during construction of the PHC pipe pile close to the factory building is solved through the measures of adjusting the piling sequence, increasing guide holes, controlling the construction speed and the like.
本发明是一种临近厂房PHC管桩的施工方法；包括以已建厂房为原点，在其原始桩的桩长1.5倍的区域范围内对将要打入的桩进行标记，所述需要打入的桩，按照与原始装维隔一跳一的形式引孔；引孔深度为桩长的2/3；引孔完成后，以已建厂房为原点，在其三排原始桩的桩基范围内的新桩的施工速度放慢至1/2倍速；施工完成后，再开始其他非影响区的施工。本发明所提出的临近厂房PHC管桩的施工方法，通过调整打桩顺序、增加引孔、控制施工速度等措施来解决临近建筑PHC管桩施工时的挤土效应。
