Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of grouting monitoring, and specifically relates to a grouting monitor. BACKGROUND

[0002] In the construction process of cast-in-place concrete structures, the reliable connection of longitudinal reinforcement is a key link to ensure the strength and stability of the structure. Traditional methods such as binding and overlapping, welding connection and mechanical connection have shown good adaptability in cast-in-place operations. However, in the face of the emerging trend of fabricated concrete structures, their unique modular design and compact connection space pose a challenge to traditional reinforcement connection methods. In order to overcome this problem, grouting sleeve technology has emerged as an innovative solution for reinforcement connection in fabricated concrete structures. As a highly integrated connection system, the core of the grouting sleeve lies in the perfect integration between the precisely machined sleeve, the specially designed fast-hardening non-shrinkage grouting material and the reinforcement to be connected. During the connection operation, the reinforcement is first accurately positioned and inserted into the sleeve, and then a dedicated grouting device is used to inject high-performance grouting material into the sleeve. This grouting material, with its fast-hardening and non-shrinkage characteristics, can form strong bonding force in a short time, and through the dual action of physical engagement and chemical bonding, it can firmly lock the reinforcement in the sleeve, achieving efficient and reliable connection. In order to ensure the quality and efficiency of the grouting process, monitoring of grouting fullness is particularly important. The traditional L-shaped connecting pipe monitor, based on the classic communicating vessel principle, cleverly uses the characteristic that the pressure in a closed container is equal, and indirectly reflects the fullness of the grouting in the sleeve by observing the change of the grouting material liquid level in the vertical branch. This design not only has a simple principle and convenient operation, but also can intuitively and effectively reflect the grouting effect, providing valuable reference for construction personnel. However, the monitoring process is not a one-time job. After the monitor shows that the grouting fullness reaches the predetermined standard, the construction personnel need to patiently wait for the grouting material to fully solidify and harden to ensure the connection strength. Then, in order not to affect the subsequent construction or avoid unnecessary interference to the structure, the monitor needs to be separated from the sleeve. At this time, by using a tool to gently knock off the part inserted into the sleeve in the horizontal branch, the two can be smoothly separated, and the whole process is safe and efficient. It is worth mentioning that with the progress of technology and the popularity of fabricated buildings, grouting sleeves and their supporting monitoring technology are also constantly iterating and upgrading. For example, the introduction of intelligent monitoring systems enables remote monitoring, real-time feedback and data analysis during the grouting process, further improving the safety and accuracy of construction. At the same time, the research and application of new grouting materials also inject new vitality into the grouting sleeve connection technology, promoting the technological progress and industrial development in the field of fabricated concrete structures.

[0003] According to Chinese Patent CN219266296U, a grouting monitoring device for easy observation is disclosed, comprising: an inlet extension pipe, which is detachably and fixedly connected to the grouting inlet of the grouting sleeve, and the inlet extension pipe is used to leave space for grouting operations; an outlet extension pipe, which is detachably and fixedly connected to the grouting outlet of the grouting sleeve, and the outlet extension pipe is used to leave space for the monitor installation; and an observation tube, which is L-shaped and detachably and fixedly connected to the end of the outlet extension pipe away from the grouting outlet, and the observation tube is transparent. This utility model, through the transparent observation tube, allows for direct observation of whether the grouting of the sleeve is full, and can monitor the degree of grouting fullness. When grout leakage or natural grout fall occurs, the liquid level in the observation tube drops simultaneously, facilitating timely handling and replenishment. This reduces the workload of grouting workers and lowers the difficulty of quality inspection personnel.

[0004] However, existing grouting monitoring equipment has different requirements for each building construction, which in turn affects the monitoring device. Traditional grouting monitoring equipment requires different types of springs to achieve the same results, causing inconvenience for users. Utility Model Content
