Movable arm set for waterproof construction and trolley for waterproof construction and with same

Abstract

The invention discloses a movable arm set for waterproof construction. The movable arm set comprises power sources, an arm body and mounting seats. The power sources comprise first power parts for controlling the arm body to act and second power parts for controlling the mounting seats to move. The arm body comprises at least one set of arm single pieces and detachable fixing pieces, the first ends of the arm single pieces are connected with the mounting seats and controlled to act through the first power parts, and the second ends of the arm single pieces are connected with the detachable fixing pieces. The arm set has the effects that the whole structure is simplified; the power sources can drive the arm single pieces to act and can also drive the mounting seats to move; and laying of awaterproof material along the tunnel construction surface is achieved, the construction requirements of different tunnel fracture surfaces can be met, and operation is convenient. The invention further discloses a trolley comprising the arm set. The height adjustable effect of a door frame system is combined with the rotatable effect or the rotatable and retractable effects or the rotatable and foldable effects of the arm set, and the movable arm set is better suitable for waterproof construction of tunnels of different cross sections.

Description

technical field [0001] The invention relates to the technical field of tunnel construction, in particular to a movable arm set for waterproof construction and a trolley for waterproof construction including the arm set. Background technique [0002] Waterproofing is an old topic. Whether it is tunnels, bridges, dams, roads, buildings, or the houses we live in, waterproofing cannot be ignored. [0003] In various tunnel construction designs, in order to avoid water leakage, waterproof materials are designed. At present, during construction, a simple waterproof board laying platform that can only be used by workers to stand is generally used for laying operations. Since the whole roll of waterproof board is relatively heavy, it is first necessary to manually lift the waterproof board to the top of the platform during the construction process, and then open it and place it on the platform.

AI Technical Summary

Problems solved by technology

At present, during construction, a simple waterproof board laying platform that can only be used by workers to stand is generally used for laying operations. Since the whole roll of waterproof board is relatively heavy, it is first necessary to manually lift the waterproof board to the top of the platform during the construction process, and then open it and place it on the platform. Manual laying on the trolley, due to the hard material of geotextiles and waterproof boards, the flatness and slack degree of manual laying and hanging are basically not guaranteed, and the uncertainties of artificial operations are relatively large, leaving a lot of troubles for the later lining construction. Hidden dangers in construction quality; manual operation is required, and the labor intensity is high

[0004] In the prior art, the laying devices on the rail-type waterproof board trolley are all fixed and cannot be adjusted. When the construction section changes, it is necessary to redesign and manufacture or replace some parts to meet the construction. The waterproof board trolley is basically completed. If a tunnel is no longer used and scrapped directly, it is a great waste of resources and construction costs
