Non-pile-cutting method static pressure prestressed pipe pile test pile top elevation control construction process
The invention discloses a non-pile-cutting method static pressure prestressed pipe pile test pile top elevation control construction process, and belongs to the technical field of building construction. The non-pile-cutting method static pressure prestressed pipe pile test pile top elevation control construction process comprises the steps that 1, an original earthwork square grid is measured, and an original site is subjected to surface clearing on site; 2, three representative test piles are selected in advance to be constructed in advance, and a static pressure load test is conducted; 3, test data are analyzed; 4, according to the pile top elevation, the height of an embedded foundation bearing platform and the final settlement amount of the test piles, pile foundations with the unified pile top pile splicing length of the test piles are prefabricated; 5, the original site elevation on site is subjected to proper surface clearing, and the later-period pile foundation static pressure load is gradually developed; and 6, after pile foundation excavation is completed, the pile foundations subjected to pile top pile splicing are cut, and next procedure construction is conducted. According to the non-pile-cutting method static pressure prestressed pipe pile test pile top elevation control construction process, the construction quality of the pile foundations of the test piles can be effectively guaranteed, the pile cutting process that the pile top elevation is not in place is reduced, and the construction period and the accuracy of the test pile data are effectively guaranteed.
本发明公开了一种非截桩法静压预应力管桩试桩桩顶标高控制施工工艺，属于建筑施工技术领域。本发明的步骤为：步骤一、测量原始土方方格网，现场原始场地清表；步骤二、预先选取有代表性的三根试桩进行提前施工并做静压荷载试验；步骤三、对试验数据进行分析；步骤四、根据桩顶标高、嵌入基础承台的高度、试桩最终沉降量，预制统一的试桩桩顶接桩长度的桩基；步骤五、对现场原始场地标高进行适当清表，保证后期桩基静压荷载逐步开展；步骤六、桩基开挖完成后，对桩顶接桩的桩基进行切割，进行下道工序施工。本发明可以有效保证试桩桩基的施工质量，减少桩顶标高不到位的截桩工艺，有效的保证了工期及试桩数据的准确性。
