GENG YONGKUI / ZHOU BO / HE PENG / CAO YUANBO

The invention provides a double-hoop supporting device and a bridge slope adjusting system. The double-hoop supporting device comprises a bottom supporting hoop, a top supporting hoop and a plurality of supporting stand columns. The bottom supporting hoop is fixedly arranged at the position of an annular step structure between the top of a pile foundation and the root of a pier column in a sleeving mode. The top supporting hoop is arranged at the preset height part of the pier column in a sleeving manner; the bottom ends of the supporting stand columns are fixedly connected with the bottom supporting hoop, and the top ends of the supporting stand columns are fixedly connected with the top supporting hoop. The top supporting hoop is used for supporting the bridge gradient adjusting platform. According to the device, the supporting device is composed of the double hoops and the supporting stand columns, the jacking slope adjusting device is erected on the supporting device, and therefore the purposes of bridge slope adjusting jacking and pier column cutting and repairing are achieved. And the problems that the underwater construction difficulty is high, the construction cost is high, the river channel is compressed by the enlarged foundation, the channel passage is influenced, and the river channel is polluted to a certain degree due to the erection and disassembly of the device are solved.

本发明提供了一种双抱箍支撑装置及桥梁调坡系统。双抱箍支撑装置包括底部支撑抱箍、顶部支撑抱箍和多根支撑立柱，底部支撑抱箍固定套设在桩基顶部与墩柱根部之间的环形台阶结构处；顶部支撑抱箍套设在墩柱的预设高度部位；多根支撑立柱的底端与底部支撑抱箍固定连接，多根支撑立柱的顶端与顶部支撑抱箍固定连接；顶部支撑抱箍用于支撑桥梁调坡平台。本发明装置采用双抱箍加支撑立柱的结构组成支撑装置，并在此装置上搭设顶升调坡装置，从而实现桥梁调坡顶升，切割修复墩柱的目的。无需临时扩大基础，解决了水下施工难度大，施工成本高，扩大基础压缩河道，影响航道通行以及装置搭设和拆除对河道造成一定程度污染的问题。
