Positioning construction method for stand column piles and latticed columns of foundation pit support structure
The invention discloses a positioning construction method for stand column piles and latticed columns of a foundation pit support structure. The positioning construction method comprises the following steps that (1) holes are formed; (2) a guide frame is installed, a guide hole is formed in the center of the guide frame, and the periphery of the guide hole, the top frame and the bottom frame are each provided with four limiting bolts which are evenly distributed in the circumferential direction and extend in the radial direction; (3) a stand column pile reinforcement cage and a latticed column enter a hole; (4) pouring of column pile concrete: after the reinforcement cage and the latticed column are put down, connecting the guide column and the pile casing together, then putting down the concrete guide pipe to a column pile hole, and pouring of concrete; and (5) the guide frame and the guide column are dismantled. It can be guaranteed that no disturbance is caused to the hole wall when the reinforcement cage is put down, it can be guaranteed that the stand column pile and the latticed column connected with the stand column pile are accurately positioned, and construction is easy and convenient.
本发明公开了一种基坑围护结构立柱桩及格构柱的定位施工方法，采用以下步骤：1)成孔；2)安装导向架，在导向架的中央设有导向孔，在导向孔的周围、顶部框架和底部框架上各设有四个沿周向均布、沿径向延伸的限位螺栓；3)立柱桩钢筋笼及格构柱入孔；4)浇筑立柱桩混凝土：钢筋笼及格构柱下放完成后，将导柱与护筒连接在一起，然后下放混凝土导管至立柱桩桩孔，浇筑混凝土；5)拆除导架及导柱。本发明不仅能够保证钢筋笼下放时不会对孔壁造成扰动，还能够保证立柱桩和与其相连接的格构柱定位准确，并且施工简便。
