Tunnel construction self-moving type waterproof plate automatically laying device

Abstract

The invention discloses a tunnel construction self-moving type waterproof plate automatically laying device. According to the tunnel construction self-moving type waterproof plate automatically layingdevice, the end portion of a bottom beam is fixedly provided with moving wheels and the upper portion of the bottom beam is fixedly provided with stand columns to form a portal frame; the upper portion of the portal frame is fixedly provided with support columns and a construction platform, a ring-shaped rail is fixed onto the support columns, and fixing screws are connected between the stand columns and the ring-shaped rail; rail chains are laid inside the ring-shaped rail; fixing shafts are provided with balance wheels in a sleeve mode and arranged on the ring-shaped rail; a linkage shaft is provided with gears and wheels; double-layer sleeves are connected with a fixing support and support rods; a reducing motor and a driving chain wheel are connected with the gears of the linkage shaft through a driving chain. The tunnel construction self-moving type waterproof plate automatically laying device overcomes defects of similar equipment and controls the construction platform to walk freely to automatically lay waterproof plates in a ring shape; no matter in a pulling, upward, lateral or roofing manner, the waterproof plates can be tightly attached to surrounding rock to ensure overall width and circumferential flat layering and further be smoothly welded between top and bottom, thereby ensuring project quality, saving construction personnel, achieving high automation degree and low cost and air pollution, and being energy-efficient and environmentally friendly.

Description

technical field [0001] The invention relates to a tunnel construction waterproof board laying device, in particular to a tunnel construction self-propelled waterproof board automatic laying device, which belongs to the field of construction machinery equipment. Background technique [0002] With the rapid development of high-speed railway and expressway construction, the quality standards for construction are getting higher and higher, and the construction requires energy saving, environmental protection, green and low carbon, reducing exhaust emissions of construction vehicles, improving the construction environment in the tunnel, reducing Reduce the labor intensity of the construction personnel in the tunnel and improve the construction quality. One of the procedures of tunnel construction is to lay waterproof boards on the inner wall of the tunnel to prevent the infiltration of water outside the tunnel. For a long time, when laying the waterproof board in the tunnel, the...

Problems solved by technology

Since the driver's field of vision is limited after the loader is lifted up, he cannot see the front of the shovel bucket, not only the labor intensity of the construction personnel is high, but also there is a relatively large safety hazard. , seriously pollute the air environment in the tunnel, and more importantly, the construction personnel have no support surface when laying the fixed waterproof board, and the waterproof board cannot be adjusted as a whole, so that the weld seam is not smooth, uneven, and even some places will swell and pack up, so This construction method has caused a great impact on the construction quality, as disclosed by the State Intellectual Property Office (application: CN104533466A) multi-functional flexible traction waterproof board laying platform, which is installed by a winch through a steel wire rope during the waterproof board laying process. However, since the waterproof board is relatively heavy and the steel wire rope rubs back and forth, it is easy to cause the wire rope to break, so this construction method affects the construction safety. There is no public disclosure of an ideal automatic tunnel construction method. Walking waterproof board automatic laying device
