Abstract
Description
Technical Field
[0001] This invention relates to the technical field of concrete component curing equipment, and in particular to the technical field of a rapid curing device for large tunnel-type concrete components. Background Technology
[0002] Large concrete components require curing after pouring to prevent cracking. In the construction industry, large concrete components are mostly prefabricated in factories and transported to the site for installation. During the pouring of large concrete components, there is a large amount of heat of hydration inside the concrete, and the high temperature at the center of the concrete creates a temperature gradient, which causes compressive stress inside the concrete and tensile stress on the surface. When the tensile stress exceeds the ultimate tensile strength of the concrete, cracks will appear on the concrete surface. This not only damages the structural safety but also easily affects the appearance quality, leading to failure to pass acceptance.
[0003] Chinese patent application number CN200820113083.5 discloses a concrete bridge pier spray curing device. Spray water pipes are installed around the top of the bridge pier, and each spray water pipe has spray holes. The spray water pipes are connected to a water tank via pipelines, valves, and a pump, thus solving the problem of automatic spray curing of concrete bridge piers. The pier body is cured evenly from top to bottom, avoiding the formation of dry-wet cycles and overcoming the shortcomings of uneven water spraying curing of pier concrete in the past. It also effectively solves the problem of cracking of the concrete surface of the pier. This spray curing device uses spray holes to spray water onto the earthen bridge pier to keep it moist. However, this method still has shortcomings. Due to the irregular shape of the bridge pier, some areas of the pier are blocked and cannot remain moist. Outdoor curing is affected by external hot and cold air currents, resulting in unstable curing effects.
[0004] Chinese patent application number CN202121261070.4 discloses a thermal insulation and moisture retention curing structure for large-volume concrete. This method involves pre-laying and fixing cooling pipe networks and temperature measuring pipes on the steel reinforcement structure of the foundation before concrete pouring. After the foundation concrete is poured, external water pumps are used to pump cooling water through the cooling pipe network to remove the heat of hydration inside the foundation concrete. The water flowing out of the outlet pipes is stored in the core tube foundation pit to form a water storage tank, thereby providing thermal insulation and moisture retention curing for the foundation concrete surface. This creates a layer of thermal insulation water curing between the concrete surface and the atmospheric environment, reducing the internal and external temperature difference of the large-volume concrete, preventing temperature stress, promoting concrete strength growth, and avoiding cracking. However, this method still has shortcomings: the use of a water storage tank for thermal insulation and moisture retention consumes a large amount of water resources and materials, resulting in high costs, complex construction processes, and low efficiency.
[0005] Traditional curing methods for large concrete components involve watering. However, due to the dry air, the water evaporates easily, making continuous curing impossible and leading to surface cracking. In cold winter weather, the moisture inside the concrete freezes, preventing it from setting and causing honeycomb, pitting, and spalling, thus affecting the quality of the large concrete components. Using water storage tanks for heat preservation and moisture retention in the curing of large concrete components consumes a large amount of water, resulting in high costs, complex construction processes, and low curing efficiency. Summary of the Invention
[0006] The purpose of this invention is to solve the problems in the prior art and to propose a rapid curing device for large tunnel-type concrete components, which can make the curing effect of large concrete components uniform and stable, with good forming quality and high curing efficiency.
[0007] To achieve the above objectives, this invention proposes a tunnel-type rapid curing device for large concrete components, comprising a conveying guide rail, an electric slide block, a component support plate, a curing tunnel, an electric heating layer, temperature sensors, fixed spray pipes, a humidity sensor, and a control center. An electric slide block is slidably mounted on the top of the conveying guide rail, and a component support plate is detachably mounted on the electric slide block. Several curing tunnels are arranged on the left side of the conveying guide rail. Several electric heating layers are evenly arranged on the inner wall of each curing tunnel. Several temperature sensors are evenly arranged inside each curing tunnel and connected to adjacent electric heating layers. Fixed spray pipes are evenly installed on the inner wall of each curing tunnel. Several humidity sensors are evenly arranged on the inner surface of each curing tunnel. A control center is located on the right side of the conveying guide rail, and the control center is connected to each of the electric slide block, electric heating layer, temperature sensors, fixed spray pipes, and humidity sensors.
[0008] Preferably, the top of the electric slide is fixedly provided with a translation guide rail, the electric translation slide is slidably provided on the translation guide rail, the top of the electric translation slide is provided with several electric lifters, the top of the electric lifters is detachably provided with component support plates, the left side of the conveying guide rail is provided with several curing tunnels, the bottom of the curing tunnel is provided with a feeding guide rail, the feeding guide rail is flush with the translation guide rail, and the control center is connected to the electric slide, the electric translation slide and the electric lifters one by one.
[0009] Preferably, the inner side of the maintenance tunnel is provided with a top guide rail, an electric sliding plate is installed on the top guide rail, a mobile water tank is fixedly installed on the electric sliding plate, a mobile water pump is installed at the bottom of the mobile water tank, a mobile spray pipe is installed at the bottom of the mobile water tank, the mobile water pump is connected to the mobile spray pipe, and a number of atomizing nozzles are evenly arranged at the bottom of the mobile spray pipe. The control center is connected to the mobile water pump and the electric sliding plate respectively.
[0010] Preferably, an electric heating constant temperature water tank is installed at the bottom of the maintenance tunnel, and a high-pressure water pump is submerged in the electric heating constant temperature water tank. The high-pressure water pump is connected to the end of a fixed spray pipeline, and several spray heads are evenly installed on the fixed spray pipeline. The control center is connected to the electric heating constant temperature water tank and the high-pressure water pump respectively.
[0011] Preferably, the bottom of the maintenance tunnel is provided with a drainage channel, and the bottom of the drainage channel is connected to an electrically heated constant temperature water tank through a particle filter layer.
[0012] Preferably, there are multiple maintenance tunnels, each with different temperatures and humidity levels.

The limit groove is movably fitted onto the top of the electric lifter.
[0014] The beneficial effects of this invention are as follows: This invention uses a conveyor rail in conjunction with an electric sliding block to quickly transport a large concrete component to a curing tunnel with varying temperatures and humidity levels. The electric sliding block is then transported into the curing tunnel via a sliding rail that works in conjunction with a feeding rail within the curing tunnel. An electric lifter on top of the electric sliding block, along with a detachable component support plate, places the large concrete component in the curing tunnel for curing operations. Temperature sensors within the curing tunnel, along with an electric heating layer, control the temperature. An insulation layer, combined with an electric lifting door at the tunnel opening, provides insulation and heat preservation for the curing tunnel, reducing [temperature fluctuations]. With low heat loss, the system controls humidity within the curing tunnel using fixed spray pipes and evenly distributed fixed humidity sensors. An electrically heated constant-temperature water tank heats and controls the temperature of the spray water flowing through the fixed spray pipes, preventing concrete cracking due to excessive temperature differences. A top guide rail, along with an electric sliding plate, moves the spray pipes from the top of the curing tunnel to locally atomize and adjust humidity evenly. Drainage channels at the bottom of the curing tunnel remove accumulated water, preventing uneven humidity caused by water seepage at the bottom of large concrete components. This ensures uniform and stable curing of large concrete components, resulting in high-quality molding and high curing efficiency.
