Abstract
Description
Technical Field
[0001] This utility model relates to the field of precast concrete segments, and in particular to a temperature monitoring and control system for concrete segments. Background Technology
[0002] Tunnel boring machine (TBM) segments are the main assembly components in TBM construction, forming the innermost barrier of the tunnel and bearing the responsibility of resisting soil pressure, groundwater pressure, and other special loads. TBM segment production typically uses high-strength, impermeable concrete to ensure reliable load-bearing capacity and waterproofing. Production mainly utilizes precast segment molds, which are formed after the concrete is poured into a sealed container. The segment molds are made of mold steel and consist of a bottom mold, four side plates, and two cover plates—specialized precast concrete molds used for tunnel segment production. After the concrete segments are poured, they must be cured at high temperatures in a steam curing chamber before demolding. Temperature monitoring and control during the steam curing process are crucial, directly affecting the quality of the concrete segments.
[0003] Currently, most tunnel segment manufacturers use temperature and humidity sensors at the top and bottom of the curing kiln to monitor the uniformity of steam distribution, rather than directly monitoring the temperature of the concrete segments. This method lacks precision, easily leading to wasted steam resources and low steam utilization efficiency. This paper proposes a concrete segment temperature monitoring and control system. This system can accurately monitor the real-time temperature of the concrete segments during the steam curing process, providing real-time feedback to the control system and allowing for timely adjustment of steam flow. This solves the problems of accurate monitoring and control of the steam curing temperature of concrete segments, as well as improving steam utilization efficiency. Utility Model Content

[0015] Example 1, such as Figure 1 As shown, a temperature monitoring and control system for concrete pipe segments includes a temperature sensor 1, a temperature controller 2, a fixed bracket 3, and a mold side plate 6. The temperature sensor 1 is installed in the threaded holes of the mold side plate 6 and the bottom arc plate. The temperature controller 2 is connected to the temperature sensor 1 and is connected to the fixed bracket 3. The fixed bracket 3 is installed on the mold side plate 6.
[0016] Temperature sensor 1 is fixed to the mold side plate 6 by hexagonal nut 4 and self-locking washer 5. Temperature sensor 1 collects the temperature of the concrete segment. Temperature controller 2 controls the temperature by adjusting the steam flow rate in the curing kiln.
[0017] The working principle is as follows:
[0018] This concrete tunnel segment temperature monitoring and control system uses hexagonal nuts 4 and self-locking washers 5 to fix temperature sensor 1 to the mold side plate 6. After the tunnel segment is poured, it enters the steam curing kiln along with the mold for steam curing. Temperature sensor 1 monitors the temperature of the concrete tunnel segment in real time and transmits the data back to temperature controller 2. Temperature controller 2 adjusts the steam flow rate in the steam curing kiln in real time according to the temperature of the tunnel segment to achieve temperature control and improve steam utilization efficiency. This concrete tunnel segment temperature monitoring and control system not only solves the problem of accurate monitoring and control of the steam curing temperature of concrete tunnel segments, but also solves the problem of improving steam utilization efficiency.
