Walking type pipe gallery formwork supporting device
Technical Field
The invention relates to the technical field of pipe gallery formwork supporting devices, in particular to a walking type pipe gallery formwork supporting device.
Background
In urban municipal road engineering, underground comprehensive pipe gallery engineering increases year by year, and most of the underground comprehensive pipe gallery engineering relates to urban pipelines, electric power and water supply and drainage moving and changing engineering. The traditional construction method of the main structure of the underground comprehensive pipe gallery is a full-hall scaffold or a hydraulic steel formwork trolley. The two traditional methods have certain disadvantages, which are mainly reflected in the following aspects:
the full-hall scaffold has a plurality of supporting members, including horizontal rods, longitudinal rods, floor sweeping rods, diagonal braces and the like, so that the space inside the pipe gallery is narrow, and operating personnel cannot normally enter the pipe gallery;
secondly, when the full-hall scaffold is adopted for construction, the side wall and the top plate need to be poured separately, and a construction joint needs to be arranged between the side wall and the top plate, so that on one hand, the cost investment is increased, and on the other hand, the construction period is longer;
thirdly, the full-hall scaffold is adopted for construction, when the scaffold is disassembled, the occupied construction site is large, the number of components is large, and the site civilized construction is poor; moreover, the underground comprehensive pipe gallery has small operation space, so that the scaffold and the template are inconvenient to transport, and the operation efficiency is very low;
fourthly, when the hydraulic steel template trolley is adopted, the trolley is high in manufacturing cost, the whole supporting system is generally heavy, structural components are complex, lateral up-and-down supports are generally required to be arranged, more internal space of the pipe gallery is occupied, and operation personnel can not conveniently enter and exit the pipe gallery; in addition, when the walking rail is used for walking, the walking rail is generally used, so that the cost is high;
fifthly, a hydraulic steel template trolley is adopted, generally, integral customized processing is adopted, the trolley is usually disposable, and the recycling rate of the trolley is low;
and sixthly, a hydraulic steel template trolley is adopted, and the trolley is manufactured in an integral mode and is not suitable for a construction section with a large curve radius, so that the clamping of the mould is easily caused, and even the trolley needs to be cut.
