The invention relates to a pipeline hole shockproof device. The pipeline hole shockproof device comprises a support, a pipeline and an elastic buffer, wherein the support is arranged in the length direction of the inner wall of a pipeline hole and is in a circular ring shape; the pipeline is arranged in the length direction of the interior of the support and is used for containing a pipeline; and a circular-ring-shaped cavity is formed between the support and the pipeline, and the elastic buffer used for absorbing shock is arranged in the circular-ring-shaped cavity. According to the pipeline hole shockproof device, in order to prevent stress concentration of the pipeline hole, on one hand, prestress is applied to the pipeline, and strain is reduced; and on the other hand, stress concentration caused by shock is structurally reduced through a spring column. The stress concentration phenomenon is relieved by adopting self-stress Portland cement concrete, and the concrete cracking condition caused by stress concentration is effectively reduced.
本发明涉及管道孔防震装置，包括：支架，沿管道孔内壁长度方向设置有支架；支架呈圆环状；管道；管道沿支架内部长度方向布置，其内用于容纳管线；以及弹性缓冲器，支架和管道之间形成圆环形腔室，圆环形腔室内具有用于吸收震动的弹性缓冲器。本发明为了防止管道孔产生应力集中，一方面对管道施加预应力，减少应变；另一方面通过弹簧柱在结构上减少震动引起的应力集中。并通过采用自应力硅酸盐水泥混凝土来缓解应力集中现象，有效降低了因应力集中造成的混凝土开裂情况。
