Construction technology for dismantling reinforced concrete cast-in-place pile
The invention discloses a construction technology for dismantling a reinforced concrete cast-in-place pile. The construction technology comprises the following steps that S1, a full-rotation drilling machine is installed; S2, a steel casing is sunk; S3, a cast iron plug pin is installed between the steel casing and a concrete pile; S4, the concrete pile is twisted off; S5, the twisted-off concrete pile is hoisted out; and S6, the steel casing is pulled out, and the full-rotation drilling machine is dismantled. The steel casing and a cast iron plug pin block are adopted to twist off an old bridge concrete pile in a segmented mode, and the twisted-off concrete pile is hoisted out in a segmented mode. Compared with a traditional gravity hammer crushing method, the dismounting efficiency of the concrete pile is effectively improved, meanwhile, the loss of the construction technology to workpieces is small, and the service life of the workpieces can be prolonged.
本发明公开了一种钢筋混凝土灌注桩拆除施工工艺，包括以下步骤：S1：安装全回旋钻机，S2下沉钢护筒，S3：在钢护筒与混凝土桩之间安装铸铁插销，S4：扭断混凝土桩，S5：将扭断的混凝土桩吊出，S6：抽出钢护筒，拆除全回旋钻机。通过采用钢护筒以及铸铁插销块来将旧桥梁混凝土桩分段扭断，将扭断的混凝土桩分段吊出。相对于传统的重力锤冲碎的方法，不仅有效提高混凝土桩的的拆除效率，同时本施工工艺对于工件的损耗较小，可提高工件的使用寿命。
