Frost lifting preventing device for pier and pile foundation
The invention discloses a frost lifting preventing device for a pier and pile foundation. The frost lifting preventing device comprises a base and a stable barrel vertically fixed to the top face of the base. Two limiting rods evenly arranged in the circumferential direction of the stable barrel are vertically fixed to the base in a penetrating manner, a sliding sleeve coaxial with the stable barrel is fixed to the middle of a movable plate in a penetrating manner, and the bottom end of the sliding sleeve movably makes contact with the top end of the stable barrel. The frost lifting preventingdevice has the beneficial effects that by means of the stable barrel, the stability of the bottom end of the pier and pile foundation is guaranteed, the base is buried in a tundra, and the stabilityof the overall structure is guaranteed; and when a movable layer is in a freezing and thawing cycle, the sliding sleeve suffers from taele upward frost lifting force, the sliding sleeve drives the movable plate to move upwards, taele above the movable plate can supply reverse resistance to the movable plate, upward movement is hindered, and the frost lifting effect is weakened. The pier and pile foundation and soil mass on the movable layer are effectively separated, the frost lifting effect is transferred to the sliding sleeve, the pier and pile foundation is prevented from directly making contact with the movable layer, by resetting the sliding sleeve, damage of the taele to the pier and pile foundation is effectively avoided, and the pier and pile foundation is prevented from toppling over.
本发明公开了一种桩柱基础防冻拔装置，其包括底座和垂直固定于底座顶面的稳固筒；底座上垂直穿设固定有两根沿稳固筒周向均匀排布设置的限位杆，活动板的中部穿设固定有一个与稳固筒同轴设置的滑套，滑套的底端与稳固筒的顶端活动接触。优点：稳固筒保证桩柱基础的底端稳定性，将底座埋设于冻土层，保证整体结构的稳固性；活动层发生冻融循环时，滑套受到冻土向上冻拔力，滑套带动活动板向上运动，活动板上方的冻土会给活动板反向阻力，阻碍向上运动，减弱冻拔作用，本发明有效分离桩柱基础与活动层土体，将冻拔作用转嫁到滑套上，避免桩柱基础与活动层直接接触，通过复位滑套，有效避免冻土对桩柱基础造成危害，防止桩柱基础倾倒。
