Description

Technical Field

[0001] This utility model relates to the technical field of precast bridge maintenance equipment, and in particular to a mobile maintenance shed for precast bridge maintenance. Background Technology

[0002] In the field of bridge construction engineering, prefabricated bridge construction technology has been widely used to improve construction efficiency, shorten construction cycle and ensure construction quality. This technology prefabricates bridge components in sections at the prefabrication site according to design specifications. After completion, each component is transported to the construction site for assembly. There is no need to set up formwork and pour concrete on the construction site, which effectively simplifies the construction process and significantly improves construction efficiency and the stability of component quality.

[0003] However, before prefabricated bridge components are assembled on site, they must undergo strict curing treatment to prevent quality problems such as cracking and insufficient strength caused by excessive moisture loss. Therefore, the curing process plays a decisive role in the final quality of prefabricated bridge components. At present, the industry usually sets up special curing sheds at the construction site to create a suitable temperature and humidity environment for the curing of prefabricated bridge components.

[0004] Chinese patent CN201420339216.6 discloses a circulating automatic spray curing system for bridge precast concrete structures. Its key feature is the installation of galvanized water pipes within the bridge precast platform, connected to an external circulating pool. A booster pump, a pressure gauge, a pressure regulating valve, and an outlet valve are sequentially installed on the main galvanized water pipe between the circulating pool and the bridge precast platform. The outlet valve is connected to a steam boiler via a steam valve. Water collection troughs are located on both sides of the bridge precast platform, with a rainwater pool at one end. The rainwater flows through a rainwater pipe to a sedimentation tank, which is connected to the lower part of the circulating pool. The outlet is connected to a movable nozzle on a stainless steel spraying bracket via a spray hose. This invention collects natural rainfall for spray curing of precast concrete components, combining spray curing and steam curing into one system. This reduces equipment investment, avoids the uncertainties of manual curing, and recycles alkaline curing water, preventing environmental pollution.

[0005] While the aforementioned patented technology can control the temperature and humidity of precast bridge concrete components, it still has shortcomings in practical application: Firstly, the curing shed needs to be built according to the pre-planned construction site, and the overall structure is immovable, only usable in a single curing area. The precast bridge components need to be transported from the prefabrication site to this fixed curing area. However, precast bridge components are usually large and heavy, and the transportation process not only consumes a lot of manpower and resources but also poses a risk of collision damage, significantly increasing the difficulty and cost of curing operations. Secondly, the length of the curing chamber inside the curing shed is limited by the fixed frame structure design, making it unable to flexibly adapt to the curing needs of precast bridge components of different specifications. If the length of the curing shed is shorter than the precast bridge component, the component cannot be fully contained in the curing chamber, resulting in inadequate local curing. If the length of the curing shed is longer than the precast bridge component, it will occupy too much construction space, reducing the utilization rate of the construction site. This defect is particularly prominent in construction scenarios with limited space. Utility Model Content
