Embodiment Construction
[0037] The present invention will be further described in detail below with reference to the accompanying drawings.
[0038] refer to figure 1 and 2 , is the structurally stable cross-river pipe bridge structure disclosed in the present invention, comprising a plurality of support frames 11 arranged on the bridge 1 and a steel pipe 7 arranged on the support frames 11 . The steel pipe 7 is provided with a conveying pipeline 8 , and the number of the steel pipe 7 is two and arranged along the width direction of the bridge 1 . The lower base 2 is fixed on the support frame 11, the upper base 3 is arranged on the lower base 2, the upper base 3 and the lower base 2 are both arranged in the shape of a door and the door shapes are opposite, and the lower base 2 and the upper base The length direction of the seat 3 is parallel to the width direction of the bridge 1 . The upper pedestal 3 and the lower pedestal 2 revolve around the vertical plane and the steel pipe 7 is arranged bet...

The invention relates to a stable river-crossing pipe bridge structure which comprises a plurality of support frames arranged on a bridge and steel pipes arranged on the support frames. Conveying pipelines are arranged in the steel pipes. Lower bases are fixed on the support frames. Upper bases are arranged on the lower bases. The upper bases and the lower bases are both in a door shape and are arranged in the vertical direction in the state in which the bending directions are opposite. The steel pipes are arranged between the upper bases and the lower bases. A lower supporting base and a transverse damping base used for horizontally clamping the two sides of the steel pipes are slidably connected to each lower base in the length direction of the lower base. An upper supporting base used for clamping the steel pipes to the corresponding lower supporting base and a stabilizing base used for being embedded into the top face of the corresponding transverse damping base are slidably connected to each upper base in the height direction of the upper base. A locking mechanism is arranged on each upper base, and a transverse moving mechanism is arranged on each lower base. Each upper baseis rotationally connected with one end of the corresponding lower base, and the rotating surface of each upper base is perpendicular to the axial direction of the steel pipes. A fixing mechanism is arranged on each lower base. The stable river-crossing pipe bridge structure has the technical effect of omnibearing energy dissipation and seismic mitigation.
Description
technical field [0001] The invention relates to the technical field of pipe bridges, in particular to a structure of a cross-river pipe bridge with stable structure. Background technique [0002] A pipe bridge is a special structure for pipelines to cross natural or artificial obstacles such as rivers, lakes, seas, railways, highways, valleys, etc. in the form of bridges. [0003] The existing authorization announcement number is CN208703280U The utility model patent document discloses a cross-river pipe bridge, which includes a plurality of support frames arranged on the bridge and steel pipes arranged on the support frames. There are two steel pipes and they are respectively arranged On both sides of the upper part of the support frame, the support frame is provided with a fixing piece for fixing the steel pipe, and the fixing piece includes a lower connecting block bolted on the support frame and an upper connecting block with one end hinged on the lower connecting block,...
