Construction method for quickly lengthening and setting long pile casing
The invention discloses a construction method for rapid lengthening and positioning of a long pile casing. The construction method comprises the steps that firstly, an adapter is installed on a drill rod of a rotary drilling rig; secondly, a first steel casing in the steel casings is hoisted to the preset construction position, and the upper end of the first steel casing is connected to the adapter; thirdly, the rotary drilling rig is started to drive the first steel casing to rotate and be inserted into the soil layer till the first steel casing falls to the first preset depth; fourthly, the first steel casing is separated from the adapter, and the adapter is lifted; fifthly, a second steel casing in the steel casings is hoisted to the preset construction position, the upper end of the second steel casing is connected with an adapter of the rotary drilling machine, and the lower end of the second steel casing is connected with the upper end of the first steel casing; and 6, the rotary excavating drill is started to drive the second steel casing to rotate and be inserted into the soil layer till the second steel casing falls to a second preset depth. The device has the effect of reducing deformation of the steel casing in the falling process.
本发明公开了一种长护筒快速接长落位施工方法,其施工方法包括步骤一：在旋挖钻的钻杆上安装转接头；步骤二：将钢护筒中的第一钢护筒吊运至预定施工位置上并将第一钢护筒的上端连接于转接头；步骤三：开启旋挖钻带动第一钢护筒转动并插入土层中，直至第一钢护筒下落至第一预定深度；步骤四：将第一钢护筒与转接头分离，并升高转接头；步骤五：将钢护筒中的第二钢护筒吊运至预定施工位置，并将第二钢护筒的上端与旋挖机的转接头连接，将第二钢护筒的下端与第一钢护筒的上端连接；步骤六：开启旋挖钻带动第二钢护筒转动并插入土层中，直至第二钢护筒下落至第二预定深度。本申请具有减少钢护筒在落位过程中的变形的效果。
