A method of rotary jacking

Abstract

The invention provides a rotary jacking device and method, which relate to the technical field of bridges. The device includes a steel column, a steel column foundation rotatably connected to the bottom of the steel column and located on the ground, a crawler installed on the steel column, and a crawler The top is connected and put on the hoop on the steel column, and the force-bearing claw is rotatably connected with the hoop; the force-bearing claw is used to connect the main arch or deck beam of the bridge; there is a track on the steel column, and the crawler is on the track Advancing and fastening; the method includes rotating the steel column and advancing the crawler along the steel column to realize the rotary jacking of the bridge deck girder, the bridge deck beam rotates to the design angle with the main arch, and then the rotating top The lifting device is converted to the main arch, also through the rotation of the steel column and the advancement of the crawler along the steel column. The crawler of the present invention can move forward along the steel column, and at the same time, the steel column can rotate vertically around the support to realize the rotary lifting of the bridge, which makes the bridge construction very convenient, with high installation efficiency, short construction period and high safety.

[0002] With the development of economy and science and technology, the per capita income continues to increase, tourism has become one of the ways of leisure and entertainment in the daily life of the people, the simple natural scenery can no longer satisfy the scenery of many people, more people want to enjoy the natural scenery At the same time, a little more different angles of view and excitement, for example, standing on the cliff to see the scenery makes people more yearning, but because the cliff itself is used as a tourist attraction without protective measures, it is not only monotonous, but also more dangerous, so it can be seen in the A sightseeing bridge is erected between the two cliffs for tourists to walk on the bridge, making them feel as if they are in the air, which can not only stimulate the senses of tourists, but also ensure the safety of tourists in the scenic spot

[0003] However, since this kind of sightseeing bridge needs to be set on two cliffs, its production, installation and construction are very dangerous, the construction is very difficult, and the construction period is also very long
