Embodiment Construction

[0043] The present invention will be described in detail below in conjunction with a specific implementation example.

[0044] The application example of this construction method is to carry out the design of the portal tower through the comprehensive analysis of the overall layout of the lifting arch rib and the width, height and maximum vertical rotation force of the arch rib. The main technical parameters are as follows: the height of the portal tower is 72 meters ( 51 meters above the bridge deck and 21 meters below the bridge deck), the cross-section of the columns and branches is 2.8 meters x 2.8 meters (center distance), and the span of the portal tower is 48.6 meters (center distance). Through force calculation and analysis, the tower can withstand 6-level wind (13.8m / s) during the vertical rotation and lifting process, and can withstand 10-level strong wind (25.3m / s) in Shenyang during the static process.

[0045] As shown in Figure 2, this construction method is main...

Abstract

The invention discloses a synchronous vertical swing lift construction method for a double inclination arc tower. The method comprises the following steps: arranging a vertical swing winch at the combination of two gate-shaped arch ribs and reinforced concrete, arranging a bearing gate type lifting tower at the position of the symmetrical central line of the arch ribs, arranging an upper lifting sustained center and a lower lifting sustained center at the top of the tower and on the arch ribs respectively, and performing symmetrical synchronous vertical swing lift through two pairs of hydraulic lifters by utilizing the symmetry character of the double arch ribs, so as to achieve the purpose of vertically swinging the arch ribs from the planimetric position to the mounting position. The construction method has the advantages that the arc tower construction difficulty is reduced, tools and materials are saved, the construction period is shortened, and the installation of two mammoth arch rib structures can be completed with high precision and high quality; aloft work of the arch ribs is converted into ground integral assembly work, the construction efficiency is high, the safety protection work is easy to organize, and the construction quality is easy to guarantee; machines and equipment required for the construction are in a small quantity, the process is simple, and the operation is safe; the construction speed is high, the manufacture cost is low, and the investment is saved.

Description

1. Technical field [0001] The invention relates to a building construction method, in particular to a construction method for synchronous vertical rotation and lifting of double inclined arch towers. 2. Background technology [0002] Computer-controlled hydraulic synchronous lifting technology is a new technology developed in recent years with broad application prospects. It has been successfully implemented in many domestic large-scale building bridge constructions and has achieved remarkable economic benefits. At the same time, with the rapid development of the national economy, people have higher requirements for the aesthetics of various architectural shapes, and many unique buildings, bridges, etc. have been created. Higher requirements are put forward. Conventional construction methods often result in long construction period and large investment. In order to adapt to the development of social economy, more new technologies and new processes are needed to meet these ac...
