Problems solved by technology

However, if the time is tight, the traverse speed of this construction method is very slow, which will lead to an extension of the construction period, which will not be able to meet the construction period
In addition, it is very troublesome to carry out restoration work, and it is difficult to reuse the temporary transition support structure after it is removed
Moreover, the construction process is complicated and the safety is not high

Embodiment Construction

[0020] The present invention will be further described below in conjunction with accompanying drawing.

[0021] Such as figure 1 and figure 2 A tie arch transverse movement construction method is shown, including main pier 1, temporary pier 3 and tie arch 7, the span of tie arch 7 is 64m, and the transverse movement method includes the following steps:

[0022] Step 1. Set up the reaction pier 5: The reaction pier 5 is a steel structure, which is installed on the upper surface of the end of the temporary pier 3, connected with the temporary pier 3 through anchor bolts, and the reaction pier 5 and the temporary pier 3 are constructed at the same time or pass through It is formed by pouring reinforcement on the temporary pier 3;

[0023] Step 2: Set up the upper slideway 9 and the glideway: the upper slideway 9 and the glideway are set between the tie rod arch 7 to be traversed, the main pier 1 and the temporary pier 3, and the upper surface of the main pier 1 is equipped wit...

Abstract

The invention discloses a traversing construction method for a tie bar arch, and relates to a bridge construction process. A main pier, a temporary pier and the tie bar arch are adopted in the method, wherein the span of the tie bar arch is 54 to 74 meters. The traversing method comprises the following steps of: 1, arranging a counterforce pier; 2, arranging an upper slipway and a lower slipway; 3, arranging and installing a jack; 4, arranging a stay wire type sensor; 5, traversing; and 6, jacking and lowering beams. By the method, the construction period is shortened, daily maintenance cost can be saved, the detached tie bar arch can be reused so as to save engineering investment to a great extent, and the method is high in safety.

Description

technical field [0001] The invention relates to a bridge construction technology, in particular to a tie-rod arch lateral movement construction method. Background technique [0002] During the construction of existing bridges, 4-hole tie-rod arches are generally used, and in-situ cast-in-place is used. But if the time is tight, the traverse speed of this construction method is very slow, which will lead to an extension of the construction period, which will not be able to meet the laying construction period. In addition, it is very troublesome to carry out restoration work, and it is difficult to reuse the temporary transition support structure after it is removed. Moreover, the construction process is complicated and the safety is not high. "Architecture and Engineering" No. 7, 2009, the article "Construction Technology of Steel Tube Concrete Tied Arch of Yanhe Super Bridge at Zhoujiawan" mainly briefly introduces the process and technology of steel tube arch processing a...
