Reinforcing structure of existing underground column and construction method
The invention discloses a reinforcing structure of an underground existing column and a construction method. The reinforcing structure of the underground existing column body is used for reinforcing an original structure column with a deep-buried column foundation and comprises a reinforcing column and a reinforcing ring beam, and the lower end of the reinforcing column penetrates through a soil layer to be connected with the column foundation; the reinforcing ring beam is located above the column foundation, arranged on the periphery of the original structure column in a surrounding mode, connected with the original structure column and connected with the upper end of the reinforcing column at the same time. The construction method comprises the following steps that a hole is drilled downwards from a ground datum till penetrating through a soil layer and reaching the interior of a column foundation; concrete is injected into the hole through a guide pipe in the drill rod, and then the bound reinforcing column steel bar is pressed into the poured concrete through a drilling machine till the reinforcing column steel bar extends into the column foundation; an operation pit is excavated, and the depth of the operation pit is matched with the height of the reinforcing ring beam; and a reinforcing ring beam surrounding the original structural column is built in the operation pit. The method is used for solving the technical problems that when the column is reinforced, the construction difficulty is large, and the construction period is long.
本申请公开了一种地下既有柱体的加固结构及施工方法。其中，地下既有柱体的加固结构用于对带有深埋柱基的原结构柱进行加固，包括：加固柱和加固环梁，加固柱下端穿过泥土层与柱基连接；加固环梁位于柱基的上方，环绕设置在原结构柱的外周，与原结构柱连接，且同时与加固柱的上端连接。施工方法包括以下步骤：从地面基准向下钻孔直至穿过泥土层并到达柱基内部；通过钻杆内的导管往孔内注入混凝土，随后用钻机将绑好的加固柱钢筋压入浇筑好的混凝土中直到伸入到柱基内；开挖操作坑，操作坑的深度与加固环梁的高度相适应；在操作坑内搭建环绕原结构柱的加固环梁。本申请用于解决对柱体进行加固时，存在施工难度大、施工周期长的技术问题。
