Abstract

The invention provides a continuous batching device and a batching method for tunnel sand foundation of immersed tube method, which can carry out automatic, continuous and accurate batching according to the designed sand / clinker mixing ratio and sand-water ratio. It mainly includes sand hopper, cement clinker hopper, control hopper door, (sand / cement clinker conveying) chain belt conveyor, (mixture conveying) belt conveyor, mixing bucket, water pump, and has the characteristics of low cost, automation, continuous operation, high precision, etc. .

Description

technical field [0001] The invention relates to the field of construction machinery, in particular to a continuous batching device and a batching method for tunnel sand foundations by immersed tube method. Background technique [0002] In the tunnel construction of immersed tube method, due to factors such as seismic resistance and liquefaction resistance of the pipe joint foundation, the sand filling (sand flow method) foundation has strict requirements on the proportion of sand and cement clinker and the mixing ratio of sand and water. The foundation sand filling construction method has the following problems: firstly, because the sand filling operation of the immersed tube tunnel is carried out on a barge, the working area is limited, and a large batching system cannot be used; secondly, manual batching is not only costly, low in efficiency, and discontinuous The professional quality of the construction personnel has a great influence on the quality of the sand filling ma...
