Double-side humidifying device and method for high-speed rail precast bridge

Abstract

The invention discloses a double-side humidifying device for a high-speed rail precast bridge. The double-side humidifying device comprising a water tank, a water pump, a humidifying pipe and a walking mechanism is characterized in that the water tank is connected with the water tank and the humidifying pipe, the humidifying pipe comprises a T-shaped top-surface humidifying set and a bottom-surface humidifying set, a T-shaped vertical pipe penetrates the gap between side wings of two neighboring beams, a T-shaped horizontal pipe is provided with nozzles which are of screw atomizing nozzles, and the top-surface humidifying set is used for humidifying and cooling the top surface of the precast bridge while the bottom-surface humidifying set is used for humidifying and cooling the bottom surface of the precast bridge. The double-side humidifying device is simple in structure, reasonable in design, high in intelligent degree, convenient to use and operate, labor saving, high in humidifying efficiency and good in maintaining effect.

Description

technical field [0001] The invention relates to a maintenance system, in particular to a maintenance system for a high-speed rail prefabricated bridge. Background technique [0002] High-speed rail prefabricated bridges are prefabricated with C50 high-performance concrete. After the concrete is poured, the reason why it can gradually solidify and harden is mainly due to the hydration of the concrete. Hydration requires appropriate temperature and humidity conditions, so in order to ensure that the concrete has suitable hardening conditions and its strength is continuously enhanced, the concrete must be humidified and cured. After the concrete is poured, if the climate is hot and the air is dry, if the humidification is not carried out in time, the moisture in the concrete will evaporate too quickly, forming a dehydration phenomenon, which will make the cement particles that have formed a gel body unable to fully hydrate and cannot be transformed into stable crystals. , lack...

AI Technical Summary

Problems solved by technology

Although the problem of mobile humidification has been solved, the water source is fixed, and the maintenance of long-distance multi-segment bridges cannot be satisfied by relying on hoses to connect to the water source of maintenance water. The working distance is limited by the length of hoses; the maintenance of the internal space of prefabricated bridges Different from the maintenance temperature and humidity requirements of the side wings, the side wings are thin and completely open and exposed, requiring multiple humidification and cooling, while the interior space hardly needs humidification, but this patent cannot treat it differently; it is impossible to humidify and cool the upper surface of the bridge. The upper surface is directly exposed to sunlight, which requires maintenance; in addition, there are many problems such as cumbersome structure, high failure rate, and low degree of intelligence.
