Construction method for dismantling tool column in concrete pouring process of cast-in-place pile
The invention relates to the technical field of cast-in-place piles, and discloses a construction method for removing a tool column in the concrete pouring process of a cast-in-place pile, comprising a pile hole, and connecting a steel pipe column and the tool column into a column body; the column body is sunk into the pile hole, a lower annular cavity is defined between the steel pipe column and the inner side wall of the pile hole, and an upper annular cavity is defined between the tool column and the inner side wall of the pile hole; a pressure relief hole is formed in the lower part of the tool column; concrete is poured to form a pile body of the cast-in-place pile, the lower annular cavity is filled with gravel, then concrete is poured into the steel pipe cavity, and a steel pipe pile is formed; and the slurry in the tool cavity is pumped out till the height of the slurry in the upper annular cavity and the height of the slurry in the tool cavity are flush with the pressure relief hole horizontally. In the suction process, slurry outside the tool column is synchronously sucked through the pressure relief hole, the water head pressure outside the tool column is effectively reduced, and the phenomenon that the slurry outside the tool column instantly rushes into the tool column when a constructor enters the tool column and disassembles the connection between the tool column and the steel pipe column is avoided.
本发明涉及灌注桩的技术领域，公开了灌注桩灌注混凝土过程中拆除工具柱的施工方法，包括桩孔，将钢管柱与工具柱连接为柱体；将柱体下沉在桩孔中，钢管柱与桩孔的内侧壁之间围合形成下环腔，工具柱与桩孔的内侧壁之间围合形成上环腔；工具柱的下部中设有泄压孔；灌注混凝土形成灌注桩的桩身，利用碎石填充满下环腔，再往钢管腔中灌注混凝土，形成钢管桩；将工具腔中的泥浆抽出，直至上环腔中的泥浆的高度以及工具腔中的泥浆的高度分别与泄压孔水平平齐。抽吸过程中工具柱外的泥浆通过泄压孔同步被抽吸，有效降低了工具柱外的水头压力，避免了在施工人员进入工具柱中，拆除工具柱和钢管柱的连接时，工具柱外的泥浆瞬时涌入工具柱内的现象。
