What are the principles of bridge bearing replacement in Liaoning 22m bridge inspection car rental? Rental telephone: 180-6251-5888 Safe and quick scheme for bridge bearing replacement: the bridge bearing is erected on the pier and abutment, and the top surface supports the bridge superstructure
The function of bridge bearing is to fix the superstructure on the pier and abutment, bear various forces acting on the superstructure and transmit it to the pier and abutment; Under the action of load, temperature, concrete shrinkage and creep, the support can adapt to the rotation angle and displacement of the superstructure, so that the superstructure can deform freely without additional internal force What are the principles of bridge bearing replacement in Liaoning 22m bridge inspection car rental The arrangement of bridge bearings is mainly related to the structural form of the bridge
Generally, the following basic principles need to be considered in the inspection car rental of Liaoning 22m bridge when arranging bearings: (1) when the superstructure is a spatial structure, the support shall be able to adapt to the deformation of the bridge along the bridge direction (x direction) and across the bridge direction (Y direction) at the same time (2) the bearing must be able to transmit vertical and hydraulic forces (3) the support shall make the longitudinal displacement, transverse displacement and longitudinal and constant rotation angles caused by the deformation of the beam as unconstrained as possible (4) a fixed bearing must be set on each coupling beam of railway bridge (5) when the bridge is located on the ramp, the fixed support shall generally be set on the abutment in the downhill direction (6) when the bridge is on a flat slope, the fixed support should be set on the front abutment in the main driving direction (7) the fixed bearing should be set at the place with large bearing reaction (8) several bearings on the same pier shall have similar rotational stiffness (9) when the bearing settlement of continuous beam may occur, the possibility of manufacturing height adjustment shall be considered In short, the layout principle of bridge replacement bearing is to facilitate the transmission of bearing reaction and make the bearing fully adapt to the free deformation of the beam body Boshi Equipment Leasing Co
