Problems solved by technology
[0002] In the construction of bridges in mountainous areas, due to the limitations of local construction technical conditions, human resources, mechanical equipment and site terrain, mountainous roads are limited by the site. If bridge erecting machines or other large-scale equipment are used to erect bridges, it will cause equipment transportation. difficulty
And when the task is small, the use of large-scale equipment does not conform to the principle of economical application, resulting in increased costs

Embodiment Construction
[0019] Take the hoisting of bridges in the Kashmir mountainous area of Pakistan as an example:
[0020] 1. The installation and construction process of the independent pole beam and slab is as follows:
[0021] Making ground anchors and laying beam transportation tracks——Assembling and erecting pole picker cranes—Moving beams in beam storage area—Moving beams to bridge head—Hooking fishing method to span beams—Dropping beams—Transversely moving to bridge positions—Lowering Beam in place - support.
[0022] 2. Construction method
[0023] 2.1 Preparations for vertical erection of the pole crane
[0024] 1) Carefully survey the on-site transportation road and hoisting site, especially the pressure-bearing condition of the ground soil (such as backfill soil) on the transportation road. Obstacles such as high-voltage lines in the sky must be eliminated by relevant parties.
[0025] 2) Familiar with the drawings and relevant technical requirements, conduct a comprehensive re...

The invention provides an independent derrick mast and beam plate mounting method, which includes: manufacturing a ground anchor, paving beam conveying rails, assembling and erecting a derrick mast crane, transferring beams from a beam storage area to a bridge head, craning crossing beams by hooks, laying down the beams and transversely moving the same to the bridge position, laying down the beams in place, and supporting. The independent derrick mast and beam plate mounting construction method is applicable to areas with narrow space, limited mechanical equipment and few beam plates and has the advantages of low investment, simplicity in operation and high efficiency and the like. In addition, on the conditions of small operation quantity, capability of meeting construction requirements and economy and practicality, the independent derrick mast and beam plate mounting method used is simple, flexible and capable of achieving a satisfied effect.
Description
technical field [0001] The invention relates to a beam installation method and belongs to the field of civil engineering methods. Background technique [0002] In the construction of bridges in mountainous areas, due to the limitations of local construction technical conditions, human resources, mechanical equipment and site terrain, mountainous roads are limited by the site. If bridge erecting machines or other large-scale equipment are used to erect bridges, it will cause equipment transportation. difficulty. And when the task is small, the use of large-scale equipment does not conform to the principle of economy and applicability, resulting in increased costs. Contents of the invention [0003] The technical problem to be solved by the present invention is to overcome the existing defects and provide a construction method for installing the independent pole beam and slab, which can better adapt to the construction environment in mountainous areas and reduce constructio...
