Description

Technical Field

[0001] The utility model belongs to the technical field of concrete protection and monitoring, and more specifically relates to a concrete cooling protection and monitoring device. Background Art

[0002] Large-volume concrete structures are complex, large in size and have high construction requirements. Large-volume concrete has a large hydration heat, poor crack resistance, and invisible internal cracks. Therefore, if the concrete cannot be effectively and evenly dissipated and maintained in time, it will easily have a great impact on the strength, durability, bearing capacity, impermeability and other aspects of the concrete, and easily cause quality accidents.

[0003] In the past, the temperature control methods for mass concrete included insulation, cooling and comprehensive methods. The insulation method reduces heat loss by covering with insulation materials, the cooling method reduces the concrete temperature by setting cooling water pipes, and the comprehensive method combines the insulation and cooling methods to achieve better temperature control effects. However, for mass concrete with a large area, maintenance must be carried out during construction. If the maintenance time is too long, the temperature difference between the inside and outside of the concrete will increase.

[0004] The publication number is CN111472358B, a patent for a method for internal cooling of a large-volume concrete foundation. The concrete is cooled internally by pre-buried water pipes, but this method cannot monitor the temperature changes of the concrete in real time, and large-area wet water maintenance is not convenient.

[0005] The publication number is CN109653205A, and the name is: A patent for a large-volume concrete curing method and its automated curing equipment. Through zoning control of concrete temperature field changes and combined with PLC, full automation of concrete curing is achieved. This curing method has high site requirements and requires wiring, which is not conducive to subsequent construction operations.

[0006] The publication number is CN219548434U, and the name is: A patent for a large-volume concrete groundwater circulation cooling system. The concrete is cooled by groundwater, but the temperature changes of the concrete cannot be monitored in real time, reducing the efficiency of the circulation cooling system. Utility Model Content

It should be understood that the specific embodiments described herein are only used to explain the utility model and are not used to limit the utility model. In addition, the technical features involved in each embodiment of the utility model described below can be combined with each other as long as they do not conflict with each other.

[0026] like Figure 1 As shown, the concrete cooling protection and monitoring device of the utility model includes a spray device 1, a steel pipe 5, a temperature measuring device, a connecting device and a three-way direct pipe 7. The spray device 1 is arranged on the top of the steel pipe 5. The steel pipe 5 is a seamless steel pipe with a diameter of 25 mm. The bottom of the steel pipe 5 is connected to the three-way direct pipe 7 through a connecting device. The diameter of the three-way diameter pipe 7 is a galvanized steel pipe with a diameter of 50 mm. The three-way direct pipe 7 is buried in concrete. The three-way direct pipe 7 is used to connect with the U-shaped pipeline 9 to transport cooling water to the spray device 1. The connecting device is a threaded joint 6, specifically a 50 mm diameter internal thread to a 25 mm diameter external thread joint.

[0027] The temperature measuring device is arranged on the steel pipe 5, and the temperature measuring device includes a thermometer 4 and a K-type temperature measuring wire 8. The bottom of the thermometer 4 is connected to one end of the K-type temperature measuring wire 8. The thermometer 4 is an inserted industrial digital display electronic thermometer; at least three K-type temperature measuring wires 8 are provided, and the lengths of the three K-type temperature measuring wires 8 decrease in sequence and are equidistantly arranged in the horizontal direction, with a spacing range of 30mm-50mm. The three K-type temperature measuring wires 8 represent the surface temperature of the concrete. The other ends of the three K-type temperature measuring wires 8 are firmly tied to the water outlet pipe and protected with a joint to prevent pollution.

[0028] The steel pipe 5 is also provided with a valve 2 and a valve-type joint 3. The valve 2 is used to control the connection between the cooling water and the spraying device, and the valve-type joint 3 is used to prevent the cooling water from flowing back.

[0029] Example 1

[0030] The construction object of this embodiment is: a certain unit undertakes to build 34F of Xiantao residential building, the foundation is a pile raft foundation, the foundation is 78.5M long, 19.14 meters wide, and 1.6-1.8 meters thick, which belongs to a large-volume concrete structure. In order to ensure the strength, bearing capacity, durability, and impermeability of the concrete structure. The U-shaped pipeline adopts mechanical connection to ensure that there is no water leakage. By pre-burying the upper, middle, and lower temperature measuring elements in different areas, the temperature of each part is monitored in real time, and the warm water is discharged through the branch pipe for wet water maintenance. Reduce the excessive temperature difference between the inside and the outside. At the same time, in order to solve the problem of material stacking, support frame erection, inconvenient water collection, slow manual maintenance, and inability to wet water maintenance on a large area at the same time during the subsequent main construction process, the branch pipe is reserved for docking with a faucet, which is convenient for workers to take water nearby and multiple people to maintain.

[0031] For this reason, Figures 2 to 5 As shown, this embodiment provides a concrete cooling protection and monitoring device, and its installation and use process is as follows:

[0032] Step 1: Use drilling equipment and variable frequency booster pumps to extract groundwater into storage tanks or reservoirs for use as water for later main construction.

[0033] Step 2: Cutting and threading the steel pipe 5, specifically: cutting the steel pipe 5 to a specified length and shape, and then processing threads on the inner and outer surfaces of the pipe end for use during installation.

[0034] Step 3: Arrange multiple concrete cooling protection and monitoring devices in the cold water pipe that transports cold water, that is, the U-shaped pipe 9 according to the area and volume. The spacing between the U-shaped pipes 9 ranges from 0.5m to 0.75m. If the main body is too long, it is advisable to arrange them from the middle to both sides.

[0035] Step 4: The foundation has bottom steel mesh and top steel mesh, which are supported by welding vertical steel support frames respectively. The U-shaped pipeline 9 is fixed to the support frame for assembly. The horizontal rods in each layer of steel pipe support frame are arranged at intervals as follows: Figure 2 As shown, the connection between the pipe openings needs to be wrapped with raw tape to prevent water leakage. The outlet branch pipe joint should be consistent with the top elevation of the foundation. It should be sealed with fine stone concrete of the same grade for later removal. The top opening of the three-way direct pipe 7 in the concrete cooling protection and monitoring device should be consistent with the top elevation of the foundation.

[0036] Step 5: Pre-embed the K-type temperature measuring wire 8.

[0037] Before pouring concrete, connect the variable frequency booster pump and the water inlet through a PE pipe with a diameter of 50 mm, and conduct a water flow test to check whether there is any leakage. After ensuring that there is no leakage, pour concrete. After the concrete pouring is completed, install the thermometer 4, and adjust the water flow rate according to the temperature change displayed on the thermometer 4. Use the spray device 1 to continuously wet the concrete at night, and close the spray device 1 during the day for manual maintenance.

[0038] The utility model discloses a concrete cooling protection and monitoring device, which buries a pipeline in concrete and connects to groundwater by arranging a spray device, a three-way direct pipe, a temperature measuring instrument and a K-type temperature measuring wire. The large volume concrete is first cooled and controlled and then sprayed by a spray device to cool the concrete surface. Since the cooling water first replaces the heat in the cold water pipe and the heat inside the concrete, it absorbs a part of the heat of the concrete. Then the cooling water is sprayed from the spray device to indirectly balance the temperature inside and outside the concrete. At the same time, the K-type temperature measuring wires are arranged in layers with equal intervals, which can effectively control the temperature of the concrete partitions. While monitoring the concrete temperature, the work efficiency of concrete maintenance is also improved.

[0039] It will be easily understood by those skilled in the art that the above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention shall be included in the protection scope of the present invention.
