The invention provides a tunnel wall concrete throwing device and a throwing engineering vehicle, which belong to the technical field of tunnel construction equipment. A tunnel wall concrete throwing device includes a base, a shell, a feeding pipe group, a power element and a rotor assembly ; Among them, the base is used to be fixed on the lifting platform of the spraying engineering vehicle; the shell is fixed on the base, and the top surface is provided with a discharge port; the feeding pipe group is fixed on the base and one end extends into the shell for Concrete is delivered to the casing; the power element is fixed on the base to provide torque; the rotor assembly is fixed on the base, one end extends into the casing, and the other end is connected to the torque output end of the power element, the rotor assembly It is used to centrifugally accelerate the concrete in the casing and throw it onto the tunnel wall through the discharge port. The invention provides a tunnel wall concrete throwing device and a throwing engineering vehicle, which have low power consumption, large concrete area thrown on the tunnel wall per unit time, and high throwing efficiency.
Description
technical field [0001] The invention belongs to the technical field of tunnel construction equipment, and more specifically relates to a tunnel wall concrete throwing device and a throwing engineering vehicle. Background technique [0002] During tunnel construction, after the tunnel is formed, the tunnel wall needs to be sprayed with a layer of concrete with pea stones. At present, the method of spraying concrete with bean stones is to use the principle of suction pump to drive the concrete in the spraying pipeline to spray on the tunnel wall through the pressure of compressed air. This method requires a large amount of compressed air as power, so it needs to use large The high-power high-pressure fan outputs compressed air, and in order to achieve the spraying pressure, the diameter of the spraying pipeline used is small, generally below 40mm, and the concrete that can be sprayed during the spraying operation is in the form of a strip with a diameter of less than 50mm. Th...
