Construction method of prestressed pipe pile
The invention relates to the technical field of buildings, and discloses a construction method of a prestressed pipe pile, which comprises the following steps of: measuring and placing a pile position in a to-be-constructed site; hoisting the tubular pile by using a pile machine, wherein the pile tip of the tubular pile is vertically aligned with the pile position and then is inserted into soil; after a pile pad is placed on the top of the pile, a pile cap is arranged in a sleeving mode, the center line of the pile cap coincides with the center line of the pile body of the tubular pile, and a hammer pad is placed on the pile cap; after the hammer pad is placed, cold hammering is carried out for 2-3 times to enable the pipe pile to be buried into the soil to be fixed in position, the perpendicularity of the pipe pile is checked, the perpendicularity deviation of the pipe pile is not larger than 1% of the pile length of the pipe pile, piling is carried out after the perpendicularity of the pipe pile is checked, and the inclination rate of a pile body is not larger than 0.8%; and when the tubular pile is driven to a preset supporting layer or reaches a preset penetration value, the hammer can be retracted. According to the construction mode provided by the embodiment of the invention, the construction difficulty is reduced, and the bearing capacity of the pipe pile is improved.
本发明涉及建筑技术领域，公开了一种预应力管桩的施工方法，包括：在待施工场地进行桩位测放；利用桩机起吊管桩，所述管桩的桩尖垂直对准所述桩位后插入土中；在桩顶放置桩垫后套入桩帽，所述桩帽的中心线和所述管桩的桩身中心线重合，并在所述桩帽上放锤垫；待所述锤垫放置好后，冷锤2‑3击使得所述管桩入土固定位置，检查所述管桩的垂直度，所述管桩的垂直度偏差不得大于所述管桩的桩长的1％，待检查所述管桩垂直度后进行打桩，所述桩身倾斜率不超过0.8％；待所述管桩施打至预设的持力层或达到预设的贯入度值时，则可收锤。本发明实施例提供的施工方式，降低了施工难度，且管桩的承载能力得到提高。
