Anti-frost heaving treatment method for bearing platform in severe cold area
The invention provides a frost heaving prevention treatment method for a bearing platform in a severe cold area. The frost heaving prevention treatment method comprises the following steps that S1, the outer vertical face of the bearing platform is trimmed; s2, boiling an asphalt mixture, wherein the asphalt mixture comprises petroleum asphalt, asbestos powder, talcum powder and high-calcium powder; s3, manufacturing a mold which is matched with the bearing platform external vertical surface or is used for dividing the bearing platform external vertical surface into multiple equal areas, pouring the boiled asphalt mixture into the mold, and cooling the asphalt mixture until the asphalt mixture is initially set for later use; and S4, a layer of boiled asphalt mixture is smeared on the outer vertical face of the bearing platform to serve as an asphalt base layer, then the mold covers the outer vertical face of the bearing platform in a buckled mode, and the mold is removed after the asphalt base layer and the asphalt mixture in the mold are bonded. The treatment method is simple in step, low in input cost, convenient to construct and good in anti-freezing treatment effect, the frost heaving prevention quality is easy to guarantee, the destructive effect of frost heaving force on a structure foundation can be effectively relieved or eliminated, and the stability of a structure is correspondingly improved.
本发明提供一种严寒地区承台防冻胀处理方法，包括以下步骤：步骤S1，对承台外立面进行修整；步骤S2，熬制沥青混合料，沥青混合料包括石油沥青、石棉粉、滑石粉和高钙粉；步骤S3，制作与承台外立面适配或者为承台外立面多等分面积的模具，将熬制完成的沥青混合料倒入模具内，待沥青混合料冷却至初凝后备用；步骤S4，在承台外立面涂抹一层熬制完成的沥青混合料作为沥青基层，再将模具扣盖在承台外立面，待沥青基层与模具内的沥青混合料粘结后去除模具。本发明处理方法步骤简单、投入成本低、施工方便且防冻处理效果好、防冻胀质量易于保证，能有效减缓或消除冻胀力对结构物基础的破坏作用，并相应提高结构物的稳定性。
