Pier body concrete spraying and maintaining system and concrete spraying and maintaining method

Abstract

The invention provides a pier body concrete spraying and maintaining system and a concrete spraying and maintaining method, and belongs to the technical field of a building machine. The pier body concrete spraying and maintaining system comprises a water supply mechanism, a time relay, a thread steel bracket, a spraying component and a pier body; the thread steel bracket is installed on the pier body, and the spraying component is installed on the thread steel bracket; a water supply mechanism is connected with the spraying component, the time relay is electrically connected with the sprayingcomponent, the time relay can control the spraying component to open or close. The concrete spraying and maintaining method realizes the automatic maintenance of the pier body concrete, improves the maintaining cost, and extends the service life of the pier body concrete.

Description

technical field [0001] The invention relates to the technical field of construction machinery, in particular to a pier body concrete spray maintenance system and a concrete spray maintenance method. Background technique [0002] In the prior art, the maintenance of concrete on the construction site is generally completed by manual sprinkling (water supply) or manual power connection and water supply to operate the spray pipeline. This type of maintenance method has the following problems: [0003] 1. Artificial watering is not standardized. In order to keep the surface of the concrete moist during the standard maintenance period after pouring and fully dissipate the heat of hydration, watering is generally more frequent in the early stage and less frequently in the later stage. However, it is difficult to sprinkle water on time by manual watering on site, often missing the watering time and reducing watering times, especially at night. [0004] 2. Inaccurate control of tem...

AI Technical Summary

Problems solved by technology

[0003] 1. Artificial watering is not standardized

In order to keep the surface of the concrete moist during the standard maintenance period after pouring and fully dissipate the heat of hydration, watering is generally more frequent in the early stage and less frequently in the later stage. However, it is difficult to sprinkle water on time by manual watering on site, often missing the watering time and reducing watering times, especially at night

[0004] 2. Inaccurate grasp of temperature and humidity

According to the requirements of the maintenance regulations, it is necessary to regularly monitor the ambient temperature and humidity on the surface of the maintenance structure (the internal temperature needs to be monitored for large-volume coagulation), so as to determine the degree of humidity and the ambient temperature and take measures for maintenance, but the on-site temperature monitoring is not enough. There is basically no monitoring of humidity, and it is difficult to achieve timely maintenance according to temperature and humidity conditions

[0005] 3. Insufficient or excessive water consumption for maintenance

The amount of watering depends on the volume and surface area of ​​the beam body. Too little watering (not enough moisture or infiltration into the interior) will result in poor curing effect, too much watering will waste water resources, and too much watering often leads to low early surface strength of concrete and thus Discoloration, water marks and other quality defects

[0006] 4. Low maintenance efficiency

Manual maintenance needs a special person to complete. Generally, a beam yard with more than 12 pedestals requires 1 to 2 dedicated maintenance workers. More maintenance workers are required during peak production periods, so the maintenance cost is higher and the maintenance efficiency is low.
