Double-layer high-pressure rotary spraying anti-seepage wall with vertical plastic laying device and its construction method

Abstract

The application relates to a vertical plastic-spreading device for inner clips of double-layer high-pressure rotary jetting anti-seepage walls, comprising a moving plate, a roller is arranged under the moving plate, a rod body is passed through the moving plate, and the end of the rod body located under the moving plate is provided with a mounting device The surface of the installation rod away from the rod body is hingedly provided with a hinge rod, the end of the hinge rod away from the installation rod is hinged and provided with a connecting rod, and the surface of the connecting rod away from the installation rod is uniformly provided with a plurality of slots along the length direction of the connecting rod Knife; hinge plates are arranged on the installation rod and located on both sides of the rod body, a hinge shaft is fixedly arranged between the two hinge plates and is rotatably connected to the rod body, and the length direction of the hinge shaft is parallel to the length direction of the connecting rod The rod body is provided with a first driving device for driving the hinge shaft to drive the mounting rod to swing back and forth, and the mounting rod is provided with a second driving device for driving the connecting rod to swing back and forth at the hinge point; The advantage of slotting efficiency.

Description

technical field [0001] The application relates to the field of anti-seepage construction, in particular to a double-layer high-pressure rotary jet anti-seepage wall with a vertical plastic-spreading device and a construction method thereof. Background technique [0002] Vertical film laying technology, its working principle is to use a special trenching machine to open a groove of a certain width and depth, lay plastic film in the groove, and then fill it with backfill to form an anti-seepage with plastic film as the main body Curtain, play the role of anti-seepage. [0003] The Chinese Patent Application Publication No. CN105735392A discloses a hydraulic vertical film laying machine, which includes a plastic film roll, a plastic film inner rod in the plastic film roll, a plastic film base at the lower end of the inner rod, a hydraulic oil pump installed on the panel, and a slurry feeding The upper end of the steel pipe is connected to the panel, the lower end of the slurry...

AI Technical Summary

Problems solved by technology

[0004] In view of the related technologies mentioned above, the inventor believes that there are the following technical defects: when it is necessary to groove grooves of different widths, it is necessary to take out the entire plastic laying machine from the formed grooves, and re-use the plastic laying machine to correct the formed grooves. Multiple width expansions reduce the efficiency of slotting for grooves of different widths
