Detachable underground substation hoisting hole plugging device and method
The invention relates to the technical field of hoisting hole plugging, and discloses a detachable underground substation hoisting hole plugging device and method. The hole wall of each hoisting hole comprises an inner hole wall, an outer hole wall and a hole wall top, wherein the hole wall top is provided with at least one step, and the top face of each step is provided with a groove; the plugging device comprises a cover plate, one or more tightening devices and a water stop strip, and the plate bottom of the cover plate is provided with at least one step matched with the hole wall top so that the cover plate can cover the hole wall top; the water stop strip is placed in the groove; and the number of the tightening devices is one or more, one end of each tightening device is fixed to the plate bottom of the cover plate, and the other end of each tightening device is fixed to the inner hole wall so that pre-tightening force can be provided for the cover plate and the inner hole wall. According to the device, the hole wall top of the hoisting hole is set to be step-shaped, and the water stop strip which expands when meeting water is placed in the groove of each step between the cover plate and the hole wall top, so that the waterproof performance of the hoisting hole of the transformer substation can be greatly improved.
本发明涉及吊装孔封堵技术领域，公开了一种可拆卸的地下变电站吊装孔封堵装置及方法，所述吊装孔的孔壁包括内孔壁、外孔壁和孔壁顶，其中，孔壁顶设置有至少一个台阶，且每个台阶的顶面均设置有凹槽；所述封堵装置包括盖板、收紧装置和止水条，盖板的板底设置有与孔壁顶相匹配的台阶，以使盖板盖合在所述孔壁顶上；止水条放置于所述凹槽中；所述收紧装置具有一个或多个，所述收紧装置的一端与所述盖板的板底固定，所述收紧装置的另一端与所述内孔壁固定，以向所述盖板与所述内孔壁提供预紧力。本发明通过将吊装孔的孔壁顶设置为台阶式，且在盖板与孔壁顶之间的每个台阶的凹槽中均放置有遇水膨胀的止水条，能够大大提高变电站吊装孔的防水性能。
