Power transmission tower plate type foundation assembly type reinforcing device and reinforcing method
The invention discloses a power transmission tower plate type foundation assembly type reinforcing device and method, and the reinforcing device comprises an original tower foundation which comprises a foundation stand column and a foundation bottom plate, the vertical face of the foundation stand column is connected with foundation embedded steel bars at intervals in the height direction, and anchor holes are formed in the periphery of the foundation bottom plate; the spiral anchor rod is installed in the anchor hole, the spiral anchor rod upwards extends out of the foundation slab by a preset height, and anchor discs are arranged on the spiral anchor rod at intervals; the prefabricated concrete slabs are installed on the periphery of the foundation stand column and located on the periphery of the anchor hole, a pouring cavity is defined by the multiple prefabricated concrete slabs, pre-embedded studs and pre-embedded steel bars are alternately arranged on the inner sides of the prefabricated concrete slabs in the height direction at intervals, and the pre-embedded steel bars are connected with the foundation embedded steel bars through lap joint steel bars; post-pouring concrete is poured in the pouring cavity. According to the method, the concrete precast slabs are used in foundation reinforcement, and a template is not used during concrete pouring, so that the construction efficiency is improved; and the spiral anchor rod is matched to further improve the bearing capacity of the foundation.
本发明公开了一种输电塔板式基础装配式加固装置及加固方法，加固装置包括：原塔基础，包括基础立柱和基础底板，基础立柱的立面上沿高度方向间隔连接有基础植筋，基础底板的四周设有锚孔；螺旋锚杆，安装于锚孔中，且螺旋锚杆向上延伸出基础底板预定高度，螺旋锚杆上间隔设有锚盘；预制混凝土板，安装在基础立柱的四周，并位于锚孔的外围，且由若干块预制混凝土板合围形成浇筑腔，预制混凝土板的内侧沿高度方向交替间隔设有预埋栓钉和预埋钢筋，预埋钢筋通过搭接钢筋与基础植筋连接，浇筑腔内浇筑有后浇混凝土。本发明通过在基础加固中使用混凝土预制板，在混凝土浇筑时，可不使用模板，提高了施工效率；配合螺旋锚杆，可进一步提高基础承载能力。
