Novel prefabricated assembled pier and construction method thereof
The invention provides a novel prefabricated assembled pier, which is characterized in that a groove is formed in the upper surface of a bearing platform, and a lower connecting device is arranged in the bearing platform; the prefabricated pier body comprises a pier body and an upper connecting device, the upper connecting device matched with the lower connecting device is installed in the pier body, an anti-shearing device is arranged at the bottom of the pier body, and the prefabricated pier body further comprises a UHPC bed mortar layer which is used for fixedly connecting the pier body with the bearing platform and matched with the anti-shearing device. The invention provides a construction method of the novel prefabricated assembled pier, which comprises the following steps that S1, a bearing platform is fixed to a bridge pile foundation or cast-in-place; S2, the prefabricated pier body is hoisted to the bearing platform; and S3, the prefabricated pier body is fixed to the bearing platform. The prefabricated pier body and the bearing platform are connected and fixed through the upper connecting device and the lower connecting device, the anti-shearing device is matched with the UHPC bed mortar layer to improve the anti-shearing capacity of the joint of the prefabricated pier body and the bearing platform, the anti-shearing device replaces manual scabbling, manpower is saved, the pier is not damaged, and the installation efficiency is improved.
本发明提供了一种新型预制拼装桥墩，包括：承台上表面设有凹槽，承台内设有下连接装置；预制墩身包括墩身本体和上连接装置，与下连接装置相配合的上连接装置安装在墩身本体内，墩身本体的底部设有抗剪切装置，还包括用于墩身本体与承台固定连接，且与抗剪装置相配合的UHPC座浆层。一种新型预制拼装桥墩的施工方法，包括以下步骤：S1：将承台固定于桥梁桩基上或现场浇筑承台；S2：将预制墩身吊装于承台上；S3：将预制墩身固定于承台上。预制墩身与承台通过上连接装置与下连接装置进行连接固定，抗剪装置与UHPC座浆层相配合提高预制墩身与承台结合处的抗剪切能力，抗剪切装置取代人工凿毛，节省人力，不损伤桥墩，提高安装的效率。
