The invention relates to the technical field of bridge engineering, and discloses a synchronous supporting jack used for bridge engineering. The synchronous supporting jack used for bridge engineering comprises a cylinder body and a supporting rod, wherein the outer side wall of the cylinder body is sleeved with an outer supporting column, the periphery of the supporting rod is fixedly connected with an auxiliary supporting cover, and the auxiliary supporting cover is movably connected with the outer side wall of the outer supporting column. According to the synchronous supporting jack used for bridge engineering, an electrorheological fluid is injected synchronously, an electric field is applied to enable the electrorheological fluid to become solid, then lifting and auxiliary supporting are conducted synchronously, the reliability of auxiliary supporting is guaranteed, meanwhile, due to the fact that auxiliary supporting is not delayed, supporting can be provided in time when the jack breaks down and leaks, a chain reaction is avoided, and due to the fact that the electrorheological fluid can be introduced through a hose, auxiliary supporting can be operated remotely like the jack, so that the construction flexibility is improved, and thus the economical efficiency and the safety are improved.

    本发明涉及桥梁工程技术领域,且公开了一种桥梁工程用同步支撑千斤顶,包括缸体和支撑杆,所述缸体的外侧壁套设有外支撑柱,所述支撑杆的外周固定连接有辅助支撑盖,所述辅助支撑盖与外支撑柱的外侧壁活动连接。该桥梁工程用同步支撑千斤顶,通过电流变液的同步注入,并施加电场使其变为固体,进而实现提升与辅助支撑同步进行,保证辅助支撑的可靠性,另同时由于辅助支撑不存在延迟,因此在千斤顶发生故障和泄漏时,可以及时提供支撑,避免发生连锁反应,其次,由于电流变液可以通过软管通入,因而辅助支撑可以与千斤顶一样,实现远距离操作,提高施工的灵活性,进而提高经济性和安全性。
