Continuous wall forming machine of underground cement soil impermeable wall

Abstract

The invention relates to a continuous wall forming machine of an underground cement soil impermeable wall. A machine chassis and a hydraulic support form a walking travel mechanism, a frame and an oblique adjusting rod are arranged on the machine chassis, the frame is adjusted to be in a perpendicular or oblique position through the oblique adjusting rod, and a vertical guide rod and a horizontal drive cylinder are arranged on the frame. A cutter drive mechanism and a cutter combination box are connected with a cutter combination chain and a cutter head, and move up and down along the vertical guide rod through a vertical drive cylinder. The cutter combination chain surrounding the two sides of the cutter combination box moves around a position between the cutter drive mechanism and the cutter head. Soil layers are cut and agitated by blades fixed on the cutter combination chain. A non-fence impermeable wall having excellent impermeable effect is really built through the machine, and the continuous impermeable wall has the advantages of uniform texture, accurate advance direction, better impermeable effect and simple technology. The continuous wall forming machine can be used for digging downwards, cutting soil layers and building the cement soil wall in one step.

Description

technical field [0001] The invention relates to a continuous wall forming machine for underground cement-soil anti-seepage walls, especially capable of horizontally cutting and stirring the in-situ soil in the form of walking and moving, and is applied in fields such as water-stop curtains to form an underground anti-seepage wall with high anti-seepage performance . Background technique [0002] At present, the vast majority of underground anti-seepage wall water-proof curtains are "fences" formed by stirring pile columns to achieve the purpose of water-proof and anti-seepage of building foundation pits, embankments and underground buildings. For example, the SMW construction method, the underground continuous wall made by such machinery and methods is to form a wall through the partial overlap between adjacent stirring piles. The thickness of the wall is uneven, the surface is uneven, and the density is uneven. The important thing is The uncertainty of the overlapping part...

Problems solved by technology

For example, the SMW construction method, the underground continuous wall made by such machinery and methods is to form a wall through partial overlap between adjacent stirring piles. The thickness of the wall is uneven, the surface is uneven, and the density is uneven. The important thing is The uncertainty of the overlapping part causes the anti-seepage effect and the strength of the wall to decrease; and, due to the limitation of mechanical equipment, the construction depth is shallow, which cannot meet the requirements of some deeper walls; at the same time, construction machinery that is not as deep as the same height Stable and easy to dump; the mechanical movement of the crawler type movement is not stable, and it is easy to produce direction displacement and deviation during the movement process, which cannot guarantee the quality of the wall
