Constant temperature control system of bridge hinged concrete based on solar heat collection

Abstract

The invention discloses a bridge joint concrete constant temperature control system based on solar heat collection, which includes a water inlet pipe, a water inlet valve arranged on the water inlet pipe, a first water pump, a first integrated control box, a solar heat collection device, The external water storage pipeline, the second water pump, the second integrated control box, the internal circulation pipeline, the water outlet valve set on the water outlet pipeline, the water outlet pipeline and the temperature detector; the water inlet pipeline is connected with the external water storage pipeline; the external water storage pipeline passes through The control valve is connected to the internal circulation pipeline; the internal circulation pipeline passes through each concrete hollow slab beam; the internal circulation pipeline is connected to the water outlet pipeline; the first integrated control box controls the opening and closing of the water inlet valve, and the first water pump pumps water to the external water storage pipeline; The second integrated control box controls the control valve, the opening and closing of the water outlet valve, and the second water pump pumps water to the internal circulation pipeline; the temperature detector detects the temperature at the bottom of the beam; the solar heat collection device is used for heating. The invention can avoid freezing and thawing damage to bridge hinged concrete.

Description

technical field [0001] The invention belongs to the field of bridge structure maintenance, in particular to a bridge hinge joint concrete constant temperature control system based on solar heat collection. 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. [0003] Hinged concrete is ...

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
