Description

Technical Field

[0001] This utility model belongs to the field of shotcrete devices for PCCP pipe production processes, specifically, it relates to a shotcrete device for PCCP pipe production processes. Background Technology

[0002] Prestressed concrete cylinder pipes (PCCPs) are widely used in large-scale water conveyance projects such as water conservancy and municipal engineering. In the PCCP pipe manufacturing process, shotcrete equipment plays a crucial role. Early shotcrete methods often had many shortcomings, such as uneven slurry mixing leading to uneven pipe strength after shotcreting; fixed nozzle angles and unstable spray pressures resulting in uneven slurry thickness, affecting pipe quality and service life. Furthermore, traditional shotcrete equipment lacked effective handling of excess material, causing material waste and a messy working environment. With the increasing demands for PCCP pipe quality and the pursuit of efficient production and energy conservation, new shotcrete equipment technologies are needed to solve these problems. Simultaneously, the trend towards automated production requires shotcrete equipment to better coordinate with the entire production line, achieving precise shotcreting, reducing manual intervention, and improving production efficiency and product quality, thus driving continuous innovation in the structure and function of shotcrete equipment used in PCCP pipe manufacturing.

[0003] Existing shotcrete devices used in PCCP pipe production processes have several problems, such as uneven spraying and difficulty in adjusting the nozzle angle. These issues not only affect production efficiency and quality but also increase production costs and complexity. Therefore, developing a multi-nozzle shotcrete device with adjustable angles is of significant practical importance. Utility Model Content
