Full-automatic spraying curing equipment for tunnel and control system of full-automatic spraying curing equipment

Abstract

The invention provides a full-automatic spraying curing equipment for a tunnel. The equipment is suitable for curing concrete at the top of the tunnel and mainly comprises a distance sensor, sprayingassemblies, a support, a lifting device, a lifting motor, a water pump, a traveling motor, a chain transmission, a vehicle body, a water tank, a magnetic flip liquidometer and an electric control cabinet. The full-automatic spraying curing equipment is easy and convenient to operate and can automatically travel, travel in the opposite direction and spray, and as needed, the equipment can also be switched to be manually controlled. The water spraying amount can be automatically adjusted to enable the water spraying amount to be in the best state, so that cracks in the surface of lining concreteare effectively reduced, the concrete lining strength and durability are guaranteed, economic benefits are indirectly generated, and the equipment is suitable for curing construction of various typesof tunnel lining concrete. By means of the equipment, construction efficiency is improved, the curing procedure cost is lowered, the concrete appearance quality is improved, air in the tunnel is purified, and safety and reliability are improved. The full-automatic spraying curing equipment further has the advantages of being concise and compact in structure, low in manufacturing cost and easy andconvenient to use.

Description

technical field [0001] The present invention relates to tunnel maintenance equipment, more precisely, tunnel automatic spray maintenance equipment and its control system. [0002] technical background [0003] With the rapid development of road construction in my country, the proportion of plateau and mountain tunnel projects has gradually increased, and at the same time, higher requirements have been put forward for the strength, impermeability and durability of tunnel lining concrete. The main support forms of the tunnel are primary support and secondary lining support. Shotcrete must be used in the primary support, and the secondary lining support is mainly poured concrete. [0004] As the humidity of the concrete changes, its volume also expands or contracts linearly. For newly poured concrete, the volume deformation caused by humidity changes is plastic shrinkage; for hardened concrete, the volume deformation caused by humidity changes is drying shrinkage. When the deh...

AI Technical Summary

Problems solved by technology

Since shrinkage is not uniform within the concrete block, this difference in volume change can create tensile stresses that promote cracks in the concrete block, thereby destroying the integrity of the surface layer and reducing its durability

[0005] In the construction of tunnel engineering, because the temperature in the tunnel is relatively constant and the air in the tunnel has a certain humidity, in the control of the concrete curing process, there is generally a phenomenon that insufficient attention is paid and the control is not strict, resulting in the maintenance of the primary support concrete and the second lining concrete. Not in place, strength and durability suffer

Moreover, due to the large cross-section and long distance of the long tunnel, artificial watering maintenance cannot ensure uniform watering, and the problem of concrete maintenance has become a common problem in tunnel construction.

[0006] At present, although there is water spraying maintenance equipment, it also requires workers to operate on site, and the level of automation is low
