Hinge joint water-proofing and freeze-proofing constant-temperature device

Abstract

The invention discloses a hinge joint water-proofing and freeze-proofing constant-temperature device. The hinge joint water-proofing and freeze-proofing constant-temperature device comprises a water inlet pipeline, a water inlet valve arranged on the water inlet pipeline, a first water pump, a first integrated control box, a solar heat collection device, an external water storage pipeline, a second water pump, a second integrated control box, an internal circulating pipeline, a water isolation membrane which is arranged on hinge joint concrete, a water outlet valve which is arranged on a wateroutlet pipeline, the water outlet pipeline and a temperature detector; the water inlet pipeline is connected with the external water storage pipeline; the external water storage pipeline is connectedwith the internal circulating pipeline through a control valve; the internal circulating pipeline penetrates through the hinge joint concrete; the internal circulating pipeline is connected with thewater outlet pipeline; the first integrated control box controls the water inlet valve to be opened and closed, and the first water pump pumps water for the external water storage pipeline; the secondintegrated control box controls the control valve and the water outlet valve to be opened and closed, and the second water pump pumps water for the internal circulating pipeline; the temperature detector detects the temperature of the hinge joint concrete; the solar heat collection device collects heat. By means of the hinge joint water-proofing and freeze-proofing constant-temperature device, the situation that the hinge joint concrete is damaged due to freeze thawing can be prevented.

Description

technical field [0001] The invention belongs to the field of bridge structure maintenance, and can avoid freeze-thaw damage and accumulation water infiltration damage to hinge joints under cold conditions and rainy and snowy weather. Background technique [0002] In today's bridge construction, beam bridges with small and medium spans often adopt the form of fabricated hollow slab girders. However, due to some structural problems of hinged concrete and imperfect construction techniques, hinged concrete often becomes the "soft underbelly" of the entire assembled hollow slab girder. The diseases of hinged concrete are common in prefabricated hollow slab girder bridges, and the development of hinged concrete diseases to a certain extent will lead to the phenomenon of single slab stress. The stress on the veneer can not only cause damage to the main girder, but also damage to the auxiliary facilities of the bridge, which poses a great threat to the service life of the bridge. ...

However, due to some problems in the structure of hinged concrete and imperfect construction techniques, hinged concrete often becomes the "soft underbelly" of the entire prefabricated hollow slab beam

The diseases of hinged concrete are common in prefabricated hollow slab girder bridges, and the development of hinged concrete diseases to a certain extent will lead to the phenomenon of single-slab stress

The stress on the single slab can not only cause damage to the main girder, but also damage to the auxiliary facilities of the bridge, which poses a great threat to the service life of the bridge
