Energy-saving concrete pier maintenance device

Abstract

The invention relates to an energy-saving concrete pier maintenance device which comprises a side spraying device, a top spraying head device, a side branch water conveying pipe, a top branch water conveying pipe, a main water conveying pipe, a water pump, a water supply pool, a side branch spraying device and a time relay. The water supply system is composed of a water supply pool, a water pump, side branch water pipes, a top branch water pipe and a main water pipe. The water pump is arranged in the water supply pool, the main water conveying pipe is communicated with the water pump, the side face branch water conveying pipes and the top branch water conveying pipes are communicated with the main water conveying pipe, the top branch water conveying pipes supply water to the top sprayer devices, and the side face branch water conveying pipes supply water to the side face spraying devices. And the spraying time of the side spraying device and the top spraying head device can be set through the time relay. The side spraying device has the beneficial effects that the side spraying device uniformly guides water to the side wall of the concrete pier by adopting a drip irrigation-like technology, and spraying rebound is avoided.

Description

technical field [0001] The present invention relates to concrete bridge pier maintenance, in particular to an energy-saving concrete bridge pier maintenance device Background technique [0002] Poured concrete needs to be cured after solidification to keep the surface of the concrete moist, so as to ensure that the hydration and hardening of the cement can proceed smoothly. If the maintenance is not carried out in time, when the concrete surface loses water, the hydration reaction of the cement will stop, and the surface will dry and shrink at the same time. Under the action of shrinkage stress, the concrete structure will produce cracks, which will affect the structural strength, safety and normal use. At present, the maintenance method of bridge pier concrete structure generally adopts manual water spraying maintenance, but along with the enlargement of road and bridge construction scale, there is no public a kind of ideal automatic spraying maintenance device and usage me...

AI Technical Summary

Problems solved by technology

If the maintenance is not carried out in time, when the concrete surface loses water, the hydration reaction of the cement will stop, and the surface will dry and shrink at the same time. Under the action of shrinkage stress, the concrete structure will produce cracks, which will affect the structural strength, safety and normal use.

At present, the maintenance method of the concrete structure of the bridge pier generally adopts manual water spraying maintenance, but with the expansion of the construction scale of roads and bridges, an ideal automatic spraying maintenance device for concrete bridge piers and its use method have not been disclosed.

However, at present, the direct watering maintenance method is widely used, which requires long-term retention of scaffolding or return ramps, which takes up a lot of construction equipment, resulting in a low turnover rate of construction equipment; maintenance personnel need to climb to the top of the pier several times a day, and the pier body and pier Sprinkling maintenance on the top requires a lot of work. The manual watering maintenance method can no longer meet the demand, and it is also prone to missing maintenance, which will cause cracks in the pier body and cause safety hazards, affecting the quality of the project and reducing the service life of the pier. At the same time, the labor intensity of the workers is high, the safety risk is high, and the operation efficiency is low; the pier body and the pier top tray are directly sprayed with water. Under the action of sunlight, high temperature and wind, the water evaporates quickly. To ensure the quality of maintenance, it is necessary to repeatedly sprinkle water for maintenance every day. ;The low pier uses the pressure of the sprinkler to directly spray water to the pier body for maintenance, but the spraying rebound rate is high; the high pier uses a submersible pump to send water to the top of the pier, and the water is affected by the pier top tray when sprinkling water, so the water cannot be sprayed all over the pier. pier body, resulting in a waste of energy consumption and water resources
