Embodiment Construction

[0017] An air ejection construction method for flying over obstacles, comprising the following steps:

[0018] (1) Tower installation: When the preparations for the foundation construction are ready, install the left and right towers on the left and right sides of the obstacles that need to be overflyed; Upside-down-type holding poles stand up, and the roots of the two holding poles must be kept on the same horizontal plane. They are connected firmly with steel wire ropes, and the moving keyholes of the holding poles are set to carry out the overall erection of the pole tower. When the top of the pole tower is 0.8m away from the ground, stop traction and carry out impact. In the test, no abnormality was found and the traction continued; when the pole tower stands at 70°, slow down the traction speed, stop traction at 80°, use the self-weight of the traction system and the reverse temporary pull wire to adjust the pole tower to the vertical position, and use the theodolite for c...

Abstract

The invention discloses a construction method for realizing barrier flyover and aerial ejection. The construction method comprises the following steps: pole and tower installation, jumpover frame erection, bullet hole setting, ejection, extradition, insulation net pavement, optical wire layout, crossing mesh removal, jumpover frame dismantling and the like. The construction method disclosed by the invention is simple to construct and convenient to operate; compared with a conventional construction method, the construction method disclosed by the invention has the advantages that the construction speed is improved by over 50%; the safety reaches 100% in the view of the construction safety; in the view of the construction process, power failure, shipping service stop and sailing stop are not required; the construction method disclosed by the invention is applicable to the three aspects, such as aerial wire stringing in different barriers, aerial wire stringing in different heights and aerial wire stringing in different purposes.

Description

technical field [0001] The invention relates to an aerial ejection construction method for flying over obstacles. Background technique [0002] With the rapid development of the national economy, the continuous improvement of people's living standards, and the rapid development of power communication facilities, the main way of power communication transmission at home and abroad is still based on line transmission. Operation Our country is full of high mountains, densely covered rivers, seas and rivers, and criss-crossing railways and highways. This has seriously hindered the erection of electric power and communication lines, and restricted the development of electric power communication. Contents of the invention [0003] The object of the present invention is to provide a convenient and effective aerial ejection construction method for flying over obstacles. [0004] Technical solution of the present invention is: [0005] A construction method for aerial ejection ove...
