Description

Technical Field

[0001] The utility model relates to the technical field of quick-setting agents, in particular to a quick-setting agent adding device. Background Art

[0002] In the process of tunnel excavation in the mine, in order to ensure the construction quality and service life of the tunnel, anchor support is first carried out after blasting and rockfall, and then shotcrete covering is carried out. In addition to concrete, a part of accelerator is added to the composition of the shotcrete slurry to promote the rapid solidification of the slurry sprayed on the tunnel wall. Accelerator is an admixture added to concrete to make the concrete quickly solidify and harden. The main types are inorganic salts and organic substances, powdered solids. Its addition amount only accounts for 2% to 3% of the cement content in concrete, but it can make the concrete initially set within 5 minutes, and the accelerator solidifies within 12 minutes. It is suitable for shotcrete construction, underwater concrete and plugging rescue projects. At present, liquid accelerators are generally connected to the liquid storage barrel through a hose and sprayed directly from one end of the hose, and then reach the top of the concrete to make the concrete dry quickly.

[0003] When the existing accelerator adding device is in use, the paint outlet hole is small, and the operator needs to manually adjust the position of the adding device continuously when spraying the accelerator. Moreover, the accelerator cannot be sprayed onto the construction slurry over a large area and very evenly, which reduces the solidification speed of the cement slurry and leads to poor solidification effect.

[0004] In view of the above-mentioned related technologies, the applicant believes that the sealing effect of a sealing fixing device for a water conservancy project data collection buoy is not good during operation, so we propose a quick-setting agent adding device. Utility Model Content
