Description

Technical Field

[0001] The utility model belongs to the technical field of bridge pier maintenance, and in particular relates to a bridge pier maintenance device in arid areas. Background Art

[0002] With the large-scale construction of infrastructure and transportation projects in Northwest my country, most concrete structures undergoing construction are stored in dry environments with large temperature differences. Due to these conditions, bridge concrete is prone to moisture loss during curing, and curing temperatures fluctuate significantly. These changes in humidity and temperature have an extremely negative impact on the performance of concrete. Currently, conventional watering is the primary method of curing bridge concrete. For concrete pier structures in dry environments, the combination of dry conditions and the verticality of the structure causes moisture loss, necessitating repeated watering, resulting in high water consumption. Furthermore, the curing temperature is also adversely affected by the large temperature difference. These factors negatively impact the performance of concrete, reducing the durability of concrete pier structures. Since piers are crucial structures for transmitting loads, deterioration in their performance will reduce the usability and safety of the entire bridge project. Utility Model Content

[0025] The working principle of the present invention is as follows: watering the outer surface of the bridge pier can not only flush away the debris on the surface to achieve the cleaning effect, but also replenish the water inside the bridge pier, and then the inner curing membrane layer 14 is coated on the outside of the bridge pier, and the inner curing membrane layer 14 and the outer curing membrane layer 12 are both water energy curing membranes, and the overlap width of the membrane at the interface position of the inner curing membrane layer 14 is not less than 50mm to prevent water loss and improve the moisturizing effect. The water-saving and moisturizing curing membrane is based on a polymer absorption material and can absorb more than 200 times its own weight in water. During the degradation process, the polymer material transfers water to the concrete curing surface through capillary action, and at the same time absorbs evaporated water during the concrete hydration process, and then acts on the concrete surface to form a circulating moisturizing system, thereby improving the curing effect and improving the quality and durability of the concrete.

Water is added to the aquifer 13 through the water inlet 8 to ensure that it can meet the maintenance and use requirements.

[0027] The western arid region has strong winds and sandstorms, so a wind power generation device can be installed next to the device to power the heating tube 10, temperature and humidity sensor 20 and other electrical components. The device is equipped with an external control box for automatically monitoring and controlling the working conditions of the heating tube 10. This is a commonly used existing technology and will not be described in detail here.

[0028] The maintenance shield and protective cover are provided with different sizes and specifications, which are adapted to the sizes and specifications of the bridge piers under actual construction. The heating components in the heating cavity 9 can be selectively used according to the changes in the construction environment.

[0029] The utility model is provided with a maintenance protection cover 1 and a protection top cover 5 on the outside of the bridge pier, which can provide all-round protection for the concrete-cast bridge pier.
