Description

Technical Field

[0001] This utility model relates to the field of tunnel engineering equipment, specifically a convenient high-pressure spraying device for initial support shotcrete. Background Technology

[0002] Tunnel engineering is a series of construction works involving the building of underground, underwater, and mountain structures (laying railways, constructing highways). It mainly includes tunnel planning, surveying, design, breakthrough control surveying, and construction. During tunnel engineering operations, an automatic concrete spraying device for initial support is needed to construct the tunnel walls. A search revealed an automatic concrete spraying device for initial support in tunnel engineering, disclosed in application number CN201721606737.3. This device includes a tractor, an electric motor, a shielding umbrella, a high-pressure pump, and a mixing tank. The tractor has wheels at its bottom, a support rod fixedly connected to its top, a high-pressure pump on one side of the support rod, and a high-pressure pump support leg at its bottom. The high-pressure pump is fixedly connected to the tractor unit by its outriggers. The electric motor drives the mixing tank to perform mixing. The solution flows into the second pipe through the solution bottle and mixes with the concrete. The high-pressure pump sucks out the mixed concrete through the second pipe, and then sprays it out through the first pipe, nozzle, and spray gun. The shield can block the falling waste material to prevent it from falling into the working equipment and causing machine failure. However, the above description still has the following defects in actual use: the spraying device avoids the problem of structural damage during use, but it is not convenient to adjust the spraying angle and height, making it inconvenient to use. Therefore, it is necessary to design a practical and convenient high-pressure spraying device for initial support shotcrete. Utility Model Content
