Prefabricated assembly type wind power tower drum foundation and assembly method
The invention relates to a prefabricated assembly type wind power tower drum foundation and an assembly method, in particular to the technical field of wind power generation. The prefabricated assembly type wind power tower drum foundation comprises a top ring and a bottom ring, the top ring is located above the bottom ring, a plurality of foundation piles are arranged on the bottom surface of the bottom ring, a bottom plate is arranged on the inner side of the bottom end of the bottom ring, and an inner cavity is formed among the top ring, the bottom ring and the bottom plate; the top ring comprises five equal parts of top component precast blocks, and the bottom ring comprises ten equal parts of bottom component precast blocks; notches are formed in the bottom of the bottom ring and used for allowing main reinforcements at the tops of the foundation piles to stretch in and anchor; abutted seams between the top component precast blocks and abutted seams between the bottom component precast blocks are staggered; and the bottom ring and the top ring are connected through replaceable high-strength pre-stressed anchor bolts, the bottom plate comprises five equal parts of bottom precast blocks, a post-cast strip is arranged in the center of each bottom precast block, a post-cast strip is arranged between each bottom precast block and the bottom ring, and a cast-in-place cushion layer is arranged on the bottom face of the bottom ring. The prefabricated assembly type wind power tower drum foundation has the technical effects that the wind power tower drum foundation can be produced in a factory flow mode, transportation is easy and convenient, hoisting and mounting are efficient, and the stress performance is excellent.
本发明涉及一种预制装配式风电塔筒基础及装配方法，特别涉及风力发电的技术领域，包括顶环和底环，所述顶环位于底环的上方，所述底环底面设置有多根基桩，所述底环底端内侧设置有底板，所述顶环、底环和底板之间形成内腔，所述顶环包括五等分的顶构件预制块，所述底环包括十等分的底构件预制块，所述底环底部设置槽口用于基桩顶部主筋伸入锚固，所述顶构件预制块之间的拼缝和底构件预制块之间的拼缝相互错开，所述底环与顶环之间采用可更换高强预应力锚栓进行连接，所述底板包括五等分的底部预制块，所述底部预制块中心设置有后浇带，所述底部预制块与底环之间设置有后浇带，所述底环底面设置有现浇垫层，本发明具有使得风电塔筒基础可采用工厂流水生产、运输简便、吊安高效和受力性能优良的技术效果。
