This application discloses a jacking support construction device and method for rapid replacement of bridge bearings, comprising: a jacking support mechanism, a base, a base plate, and a self-locking mechanism; the jacking support mechanism integrates a hydraulic jacking structure and a mechanical support structure, the hydraulic jacking structure being used to jack the box girder, and the mechanical support structure being used to support the box girder; the hydraulic jacking structure includes a hydraulic cylinder and a piston rod fitted inside the cylinder, the cylinder having inlet and outlet ports for connecting to a hydraulic station via hydraulic oil pipes; the self-locking mechanism consists of a hydraulic self-locking component and a mechanical self-locking component, the hydraulic self-locking component being located within the hydraulic jacking structure to lock the inlet and outlet ports, and the mechanical self-locking component being located within the mechanical support structure to lock the mechanical support structure; the jacking support mechanism is mounted on the base plate via the base, the base plate being fixedly placed on the support platform; the base and the base plate are provided with an adjustment mechanism for adjusting the position of the jacking support mechanism. This device eliminates the need to transport and stack support components, reducing construction steps and improving efficiency.

This invention discloses a venting detection device for an ultra-high pressure fuel distribution pipe, relating to the field of water immersion leak detection technology. It includes a detection water reservoir with two air supply connectors mounted on it. A sealing component is fixedly installed on the right-side air supply connector. Two automatic cutting components are mounted on the detection water reservoir, used to cut off the clamping ends of the fuel distribution pipe. An air intake control component is fixedly installed on the left-side air supply connector. An anti-bending and anti-winding component is installed inside the detection water reservoir. The automatic cutting components allow for automatic removal of the clamping sections at both ends of the fuel distribution pipe after leak detection. This removal can be performed during normal venting and leak detection operations, avoiding the risk of manual forgetting to remove the clamping sections. This solves the problem that current ultra-high pressure fuel distribution pipe venting detection devices are not convenient for automatically removing the clamping sections after venting detection.
