Road engineering material maintenance vehicle

Abstract

The invention discloses a road engineering material maintenance vehicle. The road engineering material maintenance vehicle comprises a trailer chassis, a maintenance tank and a water tank; the maintenance tank and the water tank are arranged on the trailer chassis parallelly, the maintenance tank is a sealed heat preservation tank body, and the water tank is closed; a water injection opening witha water injection plug is formed in the top of the water tank, and an air conditioner, a humidifier, a test-piece support, a water channel, a temperature sensor and a humidity sensor are arranged in the maintenance tank; a PLC and a power supply are arranged outside the maintenance tank, and the water channel and the water tank are connected through a water injection pump; the water channel supplies water to the humidifier, and the water injection pump, the air conditioner, the humidifier, the temperature sensor and the humidity sensor are all connected with the PLC through signal lines; and power lines of the water injection pump, the air conditioner, the humidifier and the PLC are connected with the power supply. The road engineering material maintenance vehicle is provided with the trailer chassis, and thus is convenient to drag by other power devices and easy to move, the temperature and humidity in the maintenance tank can be automatically adjusted according to the setting, the water channel is formed in the maintenance tank, the appropriate amount of water is injected into the water channel before maintenance each time, and the temperature in the maintenance tank is not influenced during humidity adjustment of the humidifier; and the road engineering material maintenance vehicle is provided with the power supply and thus is suitable for fields.

Description

technical field [0001] The invention relates to a road engineering maintenance vehicle. Background technique [0002] Semi-rigid materials are the most widely used and used road materials in the world today, and can be seen almost everywhere. It has many advantages such as strong bearing capacity and good durability. The performance of semi-rigid materials is not only related to its constituent materials and good ratio, but also inseparable from good maintenance in the later stage. Curing is a technical method to improve the hydration degree of materials by controlling the temperature and moisture migration of specimens. In road construction, in order to ensure the quality of the project, the semi-rigid base materials used are usually subjected to compression tests and shear tests. To maintain the health of road materials, the standard maintenance conditions are a temperature of 20°C ± 2°C and a relative humidity of 95% ± 5%. [0003] If the maintenance is not timely, the...

AI Technical Summary

Problems solved by technology

[0004] At present, the maintenance work of the test pieces on the road construction site is usually manual spraying. This method is harsh in ensuring the strength of the mixture. First, there will be errors in manual operation, and the test pieces cannot be accurately controlled during maintenance, which affects the test results. ; secondly, road construction sites often have poor conditions, and setting the specimen maintenance device to automatic control will get a better health care effect; thirdly, for remote mountainous areas, it takes time and energy to add water to the maintenance box each time, so in the absence of Humidity curing of specimens under water and power failure conditions will not be able to keep up, which will affect the curing effect
