The invention relates to a concrete removing method. The concrete removing method comprises the following steps that the inner surface of a transition section of a stand column is pretreated, so that the inner surface of the transition section of the stand column is separated from concrete; a hole is formed in the preset position of the stand column, and punching is carried out in the radial direction of the stand column, wherein the preset position is located below the transition section; and a chemical expanding agent is plugged into the hole, so that the concrete is crushed. According to the concrete removing method, the construction efficiency is high, traditional processes such as crushing through an air pick are not needed in the whole construction process, and noise is greatly reduced; and in addition, due to the fact that the inner surface of the transition section of the stand column is separated from the concrete, the concrete can be directly taken out, and the situation of large-scale dust pollution is avoided.
本发明涉及一种混凝土的清除方法。该混凝土的清除方法包括以下步骤：对立柱的过渡段的内表面进行预处理，使得所述立柱的过渡段的内表面和混凝土之间隔开；在所述立柱的预设位置处开洞，并沿着所述立柱的径向进行打孔，其中，所述预设位置位于所述过渡段的下方；在所述孔内塞入化学膨胀剂，使得所述混凝土破碎。上述混凝土的清除方法，施工效率高，且整个施工过程无需风镐破碎等传统工艺，大幅度降低噪音的产生，此外，由于立柱的过渡段的内表面和混凝土之间隔开，从而可以直接将混凝土取出，避免大规模出现扬尘污染的情况。
