Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of concrete curing, in particular to a culvert concrete curing device. Background Art
[0002] Culverts are usually cast from reinforced concrete. In order to enable the road to pass through the water channel smoothly without hindering traffic, drainage channels are built under the roadbed and below the road surface. Through this structure, water can flow under the road. Culverts are used to cross natural valleys and depressions to discharge floods, or to span roads of various sizes as overpasses for people, livestock and vehicles, or as water channels for farmland irrigation. Concrete curing means that after concrete is poured, it can gradually set and harden mainly because of the hydration of cement, and the hydration requires appropriate temperature and humidity conditions.
[0003] Concrete curing is to ensure the strength of concrete and prevent cracks from occurring due to surface drying of concrete. It is necessary to cure it, and watering is one of the methods of natural curing of concrete. Within 12 hours after concrete is poured at normal temperature, it must be covered for heat preservation curing. For ordinary cement, it is not less than 7 days. If the watering curing of concrete is ignored, on the one hand, the strength of concrete will decrease, and on the other hand, the concrete will not have time to replenish water during the hardening process, so it will be severely short of water and thus cracks will occur.
[0004] At present, the maintenance of tunnels at the construction site should start covering for curing after initial setting, and start watering 12 hours after final setting, covering with sheet materials such as straw, rotten straw mats, bamboo curtains, gunny bags and woven cloth. Sprinkling tools can use tools such as water pipes and buckets to ensure the humidity of the concrete. The quality of the concrete cured by this method is difficult to control, and there are the following disadvantages:
[0005] Disadvantage 1: It is impossible to ensure that the temperature difference between the inside and outside of the concrete and the cooling rate meet the specification requirements;
[0006] Disadvantage 2: The difficulty in obtaining water caused by the long front of the highway project cannot meet the curing needs;
[0007] Disadvantage 3: Due to the long front of the highway project, the cost of sprinkling curing personnel is high and the efficiency is low;
[0008] Disadvantage 4: The potential safety hazards caused by the daily frequent transportation of curing water and personnel by vehicles. Content of the Utility Model

[0026] As Figures 1 to 4 shown, a culvert concrete curing device includes a curing vehicle 1, a curing shed 2 and a connection structure
[0027] The curing vehicle 1 includes a vehicle body 11, a solar panel 12, a storage battery 13, a water tank 14 and a rainwater collection plate 15; moving wheels 16 are provided at the lower part of the vehicle body 11; the solar panel 12 is arranged on the top of the vehicle body 11, and the solar panel 12 is connected to the storage battery 13; the water tank 14 is arranged inside the vehicle body 11; the rainwater collection plate 15 is arranged on the top of the vehicle body 11 and is connected to the water tank 14 through the water inlet pipe 17

[0029] The connection structure includes a water extraction pipe 31, a water extraction pump 32 and a water supply pipe 33; the water extraction pump 32 is arranged inside the vehicle body 11, one end of the water extraction pipe 31 is connected to the lower part of the water tank 14, and the other end is connected to the water extraction pump 32; one end of the water supply pipe 33 is connected to the water extraction pump 32, and the other end is connected to the negative ion atomization disk 23
[0030] When using this device, first, rainwater is collected by the rainwater collection plate 15, and then transferred to the vertical water tank 14 through the water inlet pipe 17 for storage. The solar panel 12 and the storage battery 13 are linked to store electricity. The temperature and humidity sensor 22 monitors the temperature and humidity inside the curing shed 2. The set standard humidity is 55% and the temperature is 16°C. When the monitored temperature and humidity on-site do not meet the requirements, the water pump 32 is started, and the water in the water tank 14 is sent to the negative ion atomization disk 23 through the water extraction pipe 31 and the water supply pipe 33 to humidify and cure the concrete inside the portal bracket 21. The heater 24 is started to heat and adjust the temperature to ensure that the curing shed 2 is always at the standard temperature and humidity, guaranteeing the curing effect of the concrete. In this device, all are powered by the storage battery 13, which is very convenient.
