Cover excavation construction fender post structure and construction method
The invention discloses a cover excavation construction fender post structure and a construction method. A step part used for supporting is arranged between a cylindrical pile and a semi-cylindrical pile, a first steel bar is embedded in the cylindrical pile, a semicircular gasket is embedded in the surface of the step part, positioning holes are formed in the upper side of the gasket, and a mold used for forming an incomplete part is detachably installed on the upper side of the gasket; and positioning bolts are arranged on the semicircular plates corresponding to the positioning holes. In the preparation process of the pile, the cylindrical pile is firstly poured, then the gasket is correspondingly installed to form the step part, a semicircular plate is limited through a positioning hole in the upper side of the gasket, in the semi-cylindrical pouring process, the surface of a flat plate is covered with a layer of tinfoil or a plastic film or other partition layers, the mold does not have the bonding contact effect with the front face of concrete, and the mold can be easily demolded.
本发明公开了一种盖挖施工围护桩结构及施工方法，圆柱桩和半圆柱桩之间为用于支撑的台阶部，圆柱桩内部嵌入有第一钢筋，台阶部表面嵌入有半圆状的垫片，垫片的上侧设置有定位孔，垫片上侧可拆卸安装有用于形成残缺部的模具，半圆板对应定位孔的位置安装有定位螺栓。桩的制备过程中，先浇筑圆柱桩，然后对应安装垫片形成台阶部，通过垫片上侧的定位孔限位半圆板，在半圆柱状浇筑的过程中，在平板的表面覆盖一层锡纸、塑料膜或其他隔层，模具没有与混凝土的正面粘接接触作用，可以轻易的将模具脱模。
