Description

Technical Field

[0001] The utility model relates to the technical field of internal maintenance equipment for beam box chambers, in particular to internal maintenance equipment for prefabricated box beam chambers. Background Art

[0002] The interior of the prefabricated box girder is mainly composed of concrete. The strength and durability of concrete are crucial to the overall quality of the box girder. After the concrete is poured, the hydration reaction of the cement requires sufficient water. If the interior of the box is not adequately maintained, the concrete will lose water too quickly and become insufficient in strength. For example, during the hydration reaction, cement particles combine with water to form cementitious substances such as hydrated calcium silicate. These substances fill the pores of the concrete and make the concrete dense. If there is a lack of water, the reaction will be incomplete, which will lead to an increase in the porosity of the concrete and a decrease in strength.

[0003] Currently, workers primarily water the interior of beam box chambers. However, due to factors such as operator force, angle, and walking speed, water can easily accumulate in some areas while others remain dry. High temperatures and dry environments may require more watering, while high humidity may require less. However, workers rely solely on experience and feel, making it difficult to accurately determine the required amount. This results in low efficiency and significant quality fluctuations.
