Power transmission tower fabricated foundation for mire environment and construction method of power transmission tower fabricated foundation
The invention discloses a power transmission tower assembly type foundation for a mire environment. The power transmission tower assembly type foundation comprises a base, prefabricated concrete columns, fixing bolts and spiral anchors. The base is a hemispherical inverted-bowl-shaped base, a lower flange plate is fixed to the top face of the base, and a pouring hole and a plurality of reserved holes are formed in the hemispherical face of the base. An upper flange plate is fixed to the bottom end of the concrete column and is in bolted connection with the lower flange plate, and foundation bolts are embedded in the top of the upper flange plate. The fixing bolts are arranged in the preformed holes; and the top end of the spiral anchor extends into the preformed hole and is bolted through a fixing bolt. The foundation is prefabricated in a factory and assembled on site, so that the problems of large land acquisition area, long time, high cost, difficulty in drainage of a foundation pit in summer construction, muddy road, difficulty in entrance of a concrete tank car, long construction period, high cost, danger of charcoal burning and maintenance in winter construction, difficulty in quality guarantee and the like in cast-in-place concrete in a mire environment are solved; the construction period is greatly shortened, the construction quality is improved, and the construction cost is saved.
本发明公开了一种用于泥沼环境的输电塔装配式基础，包括基座、预制混凝土柱、固定螺栓及螺旋锚；基座为半球形倒碗状基座，其顶面固定有下法兰盘，半球面上开设有灌注孔及多个预留孔；混凝土柱的底端固定有上法兰盘，上法兰盘与下法兰盘栓接，其顶部预埋有地脚螺栓；固定螺栓设在预留孔内；螺旋锚的顶端深入预留孔内并通过固定螺栓栓接。本发明基础采用工厂预制，现场组装的形式，避免了泥沼环境中现场浇筑混凝土遇到的征地面积大、时间长、成本高，夏季施工基坑排水困难，道路泥泞，混凝土罐车入场困难，施工周期长、成本高，冬季施工烧炭养护有危险，质量保证困难等问题，大大缩短了施工周期，提高了施工质量，节约了施工成本。
