Prestress stiffening steel reinforced concrete high pile cap foundation of wind power tower
The invention provides a wind power tower prestress stiffening steel reinforced concrete high-pile bearing platform foundation which comprises a rock-socketed pile foundation, a section steel bearing platform, bearing platform post-pouring concrete and a prestress device. The bottom of the rock-socketed pile foundation is of a hollow interlayer steel pipe reinforced concrete structure, and the section steel bearing platform is of a hollow interlayer steel pipe concrete structure; four-corner shoe beams are arranged at the bottom of the profile steel bearing platform, the four-corner shoe beams at the bottom of the profile steel bearing platform are wrapped by the bearing platform post-pouring concrete to fix the bottom of the profile steel bearing platform and the top of the rock-socketed pile foundation, and the multiple sets of prestress devices are arranged in the bearing platform post-pouring concrete and used for improving the integrity of the profile steel bearing platform and the rock-socketed pile foundation on the lower portion. According to the high-pile bearing platform foundation, the problem that the stress concentration phenomenon is serious due to the fact that the cooperative stress contact area of the bottom of the tower barrel and the bearing platform concrete is small is solved, and the problem that the joint of the tower barrel and the bearing platform concrete is prone to cracking is solved.
本发明提供一种风电塔架预应力加劲型钢混凝土高桩承台基础，包括嵌岩桩基、型钢承台、承台后浇混凝土和预应力装置，所述嵌岩桩基底部为中空夹层钢管钢筋混凝土结构，型钢承台为中空夹层钢管混凝土结构，型钢承台底部设置有四角靴梁，承台后浇混凝土包覆型钢承台底部四角靴梁将型钢承台底部与嵌岩桩基的顶部固定，多组预应力装置设置在承台后浇混凝土中用于增加型钢承台与下部嵌岩桩基的整体性，本发明的高桩承台基础解决了塔筒底部与承台混凝土因协同受力接触面积小导致应力集中现象严重的问题，避免塔筒与承台混凝土连接处极易开裂等问题。
