AI Technical Summary
The existing slurry system of pipe jacking machines requires continuous water injection and drainage during construction, and the discharged slurry mixture contains a lot of impurities, making it difficult to directly recycle and reuse. This leads to resource waste and reduced construction efficiency. Especially in urban areas where space is limited, it increases transportation costs and may have an impact on the environment.
A water intake and sludge discharge device for a pipe jacking machine was designed. It adopts a sludge screening mechanism and a sludge discharge component. Larger soil clods and gravel are screened out by the sludge screening plate and crushed or squeezed into the soil layer by the sludge pressing plate. Combined with the conveying pipe and the drainage pipe, the sludge and water are recycled, reducing the frequency of water injection.
This approach enables the recycling of mud and water, reduces transportation costs and environmental impact, improves construction efficiency, and avoids the impact of mud and water overflow on the surrounding living environment.
