Embodiment approach
[0026]As an embodiment of the present invention, the slider 15 is made of elastic tube, and the slider 16 is made of elastic rubber; the slider 15 is oval, and the outside of the slider 15 is covered with a cylinder 20; Screw 18 is threaded on the cylinder 20, and the screw 18 rotates and squeezes the sliding tube 15, so that the cross-sectional area of the sliding tube 15 increases; the shape of the sliding tube 15 can be changed by tightening the screw 18, so that the sliding tube 15 cross-section is The ellipse changes to a circular shape. At this time, the elastic slider 16 deforms with the slider 15 to ensure the sealing of the slider 16 and the slider 15, so that the cross-sectional area of the slider 16 increases, and then the slider 16 is adjusted. The pressure of the fresh water in the high-pressure chamber 5 is then driven by the slider 16 to adjust the pressure of the fresh water in the high-pressure chamber 5 to ensure the normal operation of the high-pressure c...

The invention belongs to the technical field of prefabricated components, and specifically relates to a bridge stress panel prefabricated component, including a box girder, a pier is fixedly connected to the bottom of one end of the box girder, a group of mounting seats are arranged on the top of the pier, and a set of mounting seats is provided between the mounting seat and the box girder. Shock-absorbing rubber pads; a group of high-pressure chambers are provided in the box beam, and fresh water with a pressure of 3 MPa is installed in the high-pressure chamber, and the fresh water is used to prevent seawater from penetrating into the reinforced concrete of the box girder and corroding the reinforced concrete; the present invention injects water into the high-pressure chamber The high-pressure fresh water makes the fresh water maintain the maintenance of the concrete of the box girder. The high-pressure fresh water slowly seeps out from the high-pressure chamber to prevent the seawater from penetrating into the concrete. The salt precipitated in the seawater will corrode the concrete and steel bars, further ensuring the The safety of the beam and prolong the service life of the box girder.
Description
technical field [0001] The invention belongs to the technical field of prefabricated components, in particular to a bridge stress panel prefabricated component. Background technique [0002] Bridges generally refer to structures erected on rivers, lakes and seas to allow vehicles and pedestrians to pass smoothly. In order to adapt to the modern high-speed development of the transportation industry, bridges are also extended to buildings that cross mountain streams, poor geology or meet other transportation needs to make traffic more convenient. A bridge is generally composed of a superstructure, a substructure, a support and ancillary structures. The superstructure is also called a bridge span structure, which is the main structure for crossing obstacles; the substructure includes abutments, piers and foundations; Or the force transmission device installed at the supporting place of the bridge abutment; the auxiliary structures refer to the bridge head board, conical slope ...
