Problems solved by technology

[0003] Water conservancy projects generally pour concrete in a large area. After the concrete is poured, if the climate is hot and the air is dry, if the maintenance is not carried out in time, the water in the concrete will evaporate too fast, forming a dehydration phenomenon, which will make the cement particles that have formed a gel body insufficient. Hydration, unable to convert into stable crystals, lack of sufficient cohesive force, resulting in flaky or powdery shedding on the concrete surface
In addition, when the concrete does not have sufficient strength, the premature evaporation of water will also cause large shrinkage deformation and dry shrinkage cracks; for the current concrete maintenance equipment, it is usually fixed on the ground, which is not convenient for overall movement and the overall angle It is also not possible to perform adjustment operations, making the maintenance process more cumbersome for large-scale concrete maintenance

Abstract

The invention relates to the technical field of maintenance equipment, and in particular, relates to a concrete maintenance device for water conservancy construction, wherein the concrete maintenance device comprises six symmetrical telescopic sleeves, telescopic rods are slidably connected between the opposite telescopic sleeves, the telescopic sleeves are in threaded connection with bolts C, the bolts C penetrate through the telescopic sleeves and abut against the telescopic rods, and cross rods are connected between the parallel telescopic sleeves; four heating devices which are evenly distributed are detachably connected to the upper ends of the cross rods and the telescopic sleeves; the lower ends of the heating devices communicate with air pipes, the ends, away from the heating devices, of the air pipes are arranged below the telescopic rods, two sets of symmetrical exhaust fans and two symmetrical air inlet fans are detachably arranged at the upper ends of the heating devices, and the positions of the exhaust fans and the air inlet fans are symmetrical; and each telescopic sleeve is slidably connected with a sliding ring, a clamping ring is detachably connected to the lower portion of each sliding ring, each clamping ring is connected with a hard pipe in a clamped mode, the hard pipes are communicated with a plurality of evenly-distributed spray heads, and the hard pipes are communicated with connectors. Large-area water spraying humidification, temperature increasing, drying and dehumidification can be achieved, and the device can stably move on a ramp.

Description

technical field [0001] The invention relates to the technical field of maintenance equipment, in particular to a concrete maintenance device for water conservancy construction. Background technique [0002] After concrete is poured and tamped, the reason why it can gradually set and harden is mainly due to the result of cement hydration, and hydration requires appropriate temperature and humidity conditions. Therefore, in order to ensure that the concrete has suitable hardening conditions, its strength will continue to increase. , Concrete must be maintained, and most of the cement pavements that use concrete are sprinkled with water for natural maintenance, sprayed film maintenance, and plastic film wrapping maintenance. [0003] Water conservancy projects generally pour concrete in a large area. After the concrete is poured, if the climate is hot and the air is dry, if the maintenance is not carried out in time, the water in the concrete will evaporate too fast, forming a ...
