Cast-in-place pile top concrete elevation control device and installation and recycling method thereof
The invention discloses a cast-in-place pile top concrete elevation control device and an installation and recycling method thereof. The cast-in-place pile top concrete elevation control device comprises a concrete floating plate, indicating balls and a telescoping rod, wherein a concrete pouring conduit hole channel used for a concrete pouring conduit to pass through is formed in the middle of the concrete floating plate, four grout leakage holes used for concrete grout to leak out are formed in the circumference around the floating plate, and two pull rings are arranged on the portion, at the bottom ends of two telescoping rods, of the floating plate. The two telescoping rods which can stretch out and draw back in the height direction to change the height are arranged on the concrete floating plate, pull hooks are arranged at the bottom ends of the telescoping rods respectively and used for pulling the concrete floating plate, and after the telescoping rods penetrate through hangingrinds, and the top ends of the telescoping rods are provided with the indicating balls respectively. Hanging rings are fixed to clamping devices, the clamping devices can freely move up and down on hanging steel bars of a reinforcement steel cage, the hanging steel bars of the reinforcement steel cage are provided with reinforcement steel cage hanging rings which are hung on a reinforcement steelcage hanging transverse beam at a cast-in place pile hole, and the reinforcement steel cage is hung on the two sides of the transverse beam and supported by the well wall.
本发明公开了一种灌注桩桩顶混凝土标高控制装置及其安装回收方法，包括混凝土浮板、指示球和伸缩杆；所述的混凝土浮板中间开设有用于供混凝土灌注导管通过的混凝土灌注导管孔通道，浮板的四周环向开设有四个用于供混凝土泥浆漏出的漏浆孔，浮板上在两根伸缩杆底端位置设置有两个拉环，混凝土浮板上设置有两个可以在高度方向伸缩来改变高度的伸缩杆，每个伸缩杆底端均设置拉钩，用于拉动混凝土浮板，伸缩杆均穿过悬挂环后顶端设有指示球，悬挂环固定在夹持装置上，夹持装置可在钢筋笼吊筋上上下自有移动，钢筋笼吊筋上设置有钢筋笼吊环，钢筋笼吊环悬挂在钻孔灌注桩孔口的钢筋笼悬挂横梁上，钢筋笼悬挂横梁两边由井壁承担。
