Frost heaving hazard prevention method for concrete pipe pile
The invention discloses a concrete pipe pile frost heaving hazard prevention method which comprises the following steps: step 1, cleaning an inner cavity wall of a concrete pipe pile, and removing oil stains on the inner cavity wall of the concrete pipe pile; 2, uniformly stirring the waterproof sealing coating in the container, adding clean water, rubber powder and a catalyst, and uniformly stirring; thirdly, the inner cavity wall of the concrete pipe pile is thinly coated with a layer of coating which is evenly stirred in the container, and the inner cavity wall of the concrete pipe pile is coated with the coating after the remaining coating in the container stays and becomes sticky; the concrete pipe pile has the beneficial effects that the hydrophobic elastic material is additionally arranged on the inner cavity wall of the concrete pipe pile, and when water in the concrete pipe is frozen and extruded to be expanded, the elastic material is compressed to release space; and when ice in the concrete pipe melts, the elastic material recovers to the original shape to leave a deformation space for next extrusion and expansion, so that the concrete pipe pile is effectively prevented from being damaged by extrusion and expansion force exceeding the bearing capacity of the concrete pipe pile.
本发明公开了一种混凝土管桩防冻胀危害方法，所述方法如下：步骤一：对混凝土管桩内腔壁进行清洁，去除混凝土管桩内腔壁油污；步骤二：对容器内的防水密封涂料进行搅拌均匀，再加入清洁水、橡胶粉、催化剂搅拌均匀；步骤三：先用容器内搅拌均匀的涂料在混凝土管桩内腔壁上薄涂一层，容器内剩余的涂料停留变成粘稠状后再在混凝土管桩内腔壁上涂覆；本发明的有益效果是：混凝土管桩内腔壁上加装憎水型弹性材料，当混凝土管内水结冰挤胀时，弹性材料被压缩释放空间；当混凝土管内冰融化时，弹性材料恢复原状为下次被挤胀留下变形空间，从而有效避免混凝土管桩受超过其承受能力的挤胀力被破坏。
