Description

Technical Field

[0001] The utility model relates to the technical field of seam measurement, in particular to a composite seam measurement device. Background Art

[0002] The sluice gate is an important control structure in the water conservancy project system. It is one of the beneficial means to scientifically manage and dispatch floods and ensure the supply of water resources. In order to ensure the normal and safe use of the concrete structure of the sluice project, the concrete structure needs to be verified for crack resistance. Therefore, most hydraulic concrete components are allowed to have cracks of a certain width. In addition, in order to avoid and eliminate the deformation and damage of the concrete structure of the sluice project caused by temperature expansion and contraction, foundation settlement and earthquake collision, structural joints such as expansion joints, settlement joints and seismic joints are set between two adjacent hydraulic concrete components or two parts of concrete components.

[0003] In order to standardize the safety monitoring of sluices and grasp the operation status of the project, according to the relevant regulations and requirements of the "Technical Specifications for Safety Monitoring of Sluices" (SL768-2018) of the Ministry of Water Resources, monitoring of concrete cracks and structural joints in sluice projects is an important guarantee for reflecting the crack resistance of hydraulic concrete components, analyzing and warning of deformation and damage of concrete structures, and monitoring the safe operation of sluices. It is also one of the necessary monitoring items in sluice project management.

[0004] The most common and simple monitoring method for cracks and structural joints in traditional concrete structures of sluice projects is to bury a pair of metal marks on both sides of the cracks and structural joints, and manually use a vernier caliper to measure the horizontal distance between the two marks to monitor the opening and closing of the cracks and structural joints. This monitoring method has personal error defects due to differences in the sensory reactions or habits of different observers.

[0005] In addition, crack and structural joint monitoring is currently mostly done with vibrating string joint meters. When measuring, the joint meter uses an electromagnetic coil to pluck the steel string and measure its vibration frequency. The frequency signal is transmitted to the data acquisition system via a cable, and the change in the relative displacement of the cracks and structural joints of the measured structure can be obtained after conversion. The monitoring accuracy of the vibrating string joint meter is relatively high, but the joint meter is easily disturbed by external environments such as light, temperature, humidity, and electromagnetic fields, and there are also certain instrument error inducements. How to effectively compare and fit the automatic monitoring of the instrument and manual measurement to eliminate measurement errors is a direction that water conservancy technicians need to explore and research.
