Problems solved by technology
[0003] In the construction of the elevated pedestrian walkway in the mountain, due to the requirement of environmental protection, large-scale mechanical equipment cannot be opened, so there is no large-scale ground crane to cooperate in the whole construction process except the entrance; the pedestrian walkway is inevitably designed with a large curvature to adapt to the trend of the mountain. The road surface of the road, the bridge deck crane cannot be constructed along the whole process under the obstruction of the road surface with large curvature curve

Embodiment Construction
[0025] The present invention will be described in further detail below in conjunction with the accompanying drawings and embodiments.
[0026] A kind of hoisting method of elevated sidewalk in mountainous area, such as figure 1 As shown, the pavement module 2 is hoisted by the ground crane 1 at the entrance section, and the bridge deck crane 3 and the transport trolley 4 are hoisted onto the pavement module 2, and the transport trolley 4 is used to transport the pavement module 2 to be installed (the ground crane 1 and then the The pavement module 2 to be installed is hoisted onto the transport trolley 4, and the transport trolley 4 loads the pavement module 2 to be installed from the entrance section and transports it to the bridge deck crane 3. After the bridge deck crane 3 takes it away and sends the pavement module 2 to be installed, The transport trolley 4 returns to the entrance section to load the pavement module 2 to be installed in the next section, and the transport ...

The invention relates to a method for hoisting a mountain land overhead pedestrian way. The method includes the steps that road surface modules are hoisted on an entrance through a ground crane, and bridge floor cranes and transport trolleys are hoisted to the road surface modules; the transport trolleys are used for conveying the to-be-installed road surface modules, and the bridge floor cranes are used for installing the to-be-installed road surface modules forwards; the bridge floor cranes conduct forward construction along straight line or small-curvature curves with rails; when the bridge floor cranes conduct construction to large-curvature curves without rails, the road surface modules in front of the large-curvature curves are installed within the operating range firstly, and then one bridge floor crane is additionally assigned to be hoisted to the large-curvature curve; and one bridge floor crane is used for hoisting another bridge floor crane to the road surface modules in front of the large-curvature curves, the hoisted-away bridge floor crane is used for hoisting the bridge floor crane left in situ to the road surface modules in front of the large-curvature curve, and the bridge floor cranes pass all the large-curvature curves in a cyclic opposite hoisting manner till construction is finished.
Description
technical field [0001] The invention belongs to the field of building construction, and in particular relates to a method for hoisting a mountain elevated pedestrian walkway. Background technique [0002] In order to improve efficiency, the elevated rail hoisting technology is used in rail traffic and road and bridge construction. The nodes are divided into several pavement modules for segmental hoisting. The pavement modules are equipped with rails, and the bridge deck cranes can complete the transportation and splicing tasks along the rails. Since rail traffic and road bridges are generally straight lines or small curvature curves, the bridge deck crane can move forward along the side of the rails until it completes the journey or completes the docking with the next construction area. Large curvature curves cannot be equipped with rails, and bridge deck cranes cannot pass along large curvature curves. The solution is to use large-scale ground cranes for direct hoisting at ...
