Shotcrete support is a form of support widely used in underground engineering. The application of this method of support depends to a great extent on the research and development of spray concrete tools. This article will provide an overview of the research and development of these devices in China, focusing on the achievements made in recent years and looking forward to its development prospects. Shotcrete support is a new type of support technology used in underground construction projects. Due to the continuous improvement of construction equipment and its superiority, its application is more and more extensive. At present, the sprayed concrete equipment used in China includes concrete jets, jet manipulators, concrete batching and feeding devices, and jetting units.
