Problems solved by technology

The grout injected in subway shield construction is mainly composed of sand, gravel, cement, coal powder ash, and bentonite. These materials need to be fully stirred before being sent into the shield tunnel. , the feeding speed is slow, which affects the construction progress
Moreover, after mixing the pressure-injected grout, it is necessary to clean the mixing equipment such as the horizontal mixer for the next use. The prior art is extremely inconvenient for cleaning the horizontal mixer, which is time-consuming and laborious, and increases labor costs.

Abstract

The invention discloses a slurry mixing device based on subway shield construction. The device comprises a rail, a trolley, a winch, a spiral conveyor, a sand field and a horizontal stirring machine;the horizontal stirring machine comprises a feed cylinder and a rack, the feed cylinder is arranged on the rack through a connecting shaft, a racket wheel is connected to the connecting shaft, a pawlmatched with the racket wheel is arranged on the rack, and an adjusting mechanism is arranged between the racket wheel and the rack. The device can simply and conveniently carry out comprehensive dead-corner-free flushing on the interior of the stirring machine, the service life of the stirring machine is prolonged, the material conveying and stirring speed is high, guarantee is provided for rapidconstruction, and the construction efficiency is improved.

Description

technical field [0001] The invention relates to slurry mixing equipment based on subway shield construction. Background technique [0002] Shield method is a comprehensive construction technology. The main content of the shield tunneling method construction is: first build a shaft or foundation pit at one end of a certain section of the tunnel for the shield to be installed in place. The shield starts from the reserved hole in the wall of the vertical shaft or foundation pit, and advances to the designed reserved hole of another vertical shaft or foundation pit along the design axis in the stratum. The stratum resistance encountered during shield tunneling is transmitted to the assembled prefabricated lining at the tail of the shield through the shield jack. The shield is a circular steel cylinder structure that can support the formation pressure and can be pushed in the formation. Its diameter is slightly larger than the diameter of the tunnel lining. Various types of sup...
