Description

Technical Field

[0001] The present invention relates to the technical field of concrete curing, and in particular to a road and bridge curing device. Background Art

[0002] Concrete maintenance improves the quality of concrete mainly by promoting full hydration of cement to reduce internal defects and reducing the temperature difference between the interior and surface of large-volume concrete to avoid cracks. Bridge concrete maintenance is the process of continuous hydration of cement under conditions of sufficient moisture and temperature, and the gradual maturation and hardness development of bridge concrete. In order to obtain high-quality bridge concrete, maintenance should begin immediately after concrete pouring. For bridges built in plateau areas, traditional maintenance methods are not suitable for plateau areas due to the large temperature difference between day and night and dry air.

[0003] Through research, it is found that longer-term wet curing will increase the surface permeability of concrete. At the same time, wet curing will effectively reduce the average number of cracks and the average void area in concrete. In addition, as the temperature increases during curing, the impermeability of concrete will be enhanced. It is concluded that long-term wet curing of concrete while maintaining a certain temperature can effectively enhance the performance of concrete.

Since the sealing film 3 is elastic, the edges of the two rotating rods 26 are connected to the sealing film 3 to prevent the edges of the sealing film 3 from tearing. At the same time, when the sealing film 3 is pulled, the support arm 23 will be pulled by the sealing film 3 to rotate. When the two sealing frames 15 and the two sealing frames 16 are in contact with each other, the two rotating rods 26 are in contact with each other to reduce air exchange with the outside.

[0025] In summary, the working principle of this road and bridge maintenance device is: The output end of motor 1 6 drives the winding shaft 8 to rotate, and the winding shaft 8 drives the traction rope 9 to pull the traction frame 5 to lift and lower. The output end of motor 2 7 drives the guide plate 13 to reciprocate to arrange the traction rope 9.

The water flows to the return water port 19, is heated by the heating pipe 20, and is sent to the return water pipe 18 through the water pump 21. The hot water is sprayed on the bridge pier again through the nozzle 17.
