Embodiment 1

[0024] The stepped construction technology of the corrugated steel web bridge is divided into N sections, N+1 sections, and N+2 sections according to the sequence of construction sections along the longitudinal direction of the bridge. The steel web 2 is located between the top plate 1 and the bottom plate 3, and works in three sections: 1. Construction of the top plate 1 in the N section, construction of the bottom plate 3 in the N+1 section; 2. Installation of the corrugated steel web 2 in the N+2 section ; 3. After the above-mentioned three sections are completed, each enters the next section in turn;

[0025] Only one construction work is carried out at the same time in the vertical space where each segment is located.

[0026] Each step works independently within each segment.

[0027] In the three-section operation method, the installation section of the corrugated steel web 2 is one section ahead of the bottom plate 3, and the installation section of the corrugated ste...

Embodiment 2

[0033] The stepped construction technology of the corrugated steel web bridge is divided into N sections, N+1 sections, and N+2 sections according to the sequence of construction sections along the longitudinal direction of the bridge. The steel web 2 is located between the top plate 1 and the bottom plate 3, two sections work: a. N section constructs the top plate 1, N+1 section first installs the corrugated steel web 2, and then constructs the N+1 section bottom plate 3, b . After the above two segment operations are completed, each enters the next segment in turn.

[0034] Only one construction work is carried out at the same time in the vertical space where each segment is located.

[0035] Except for step a, each section in the remaining steps works independently.

[0036] In the two-section operation method: the installation section of the corrugated steel web 2 and the bottom plate 3 are located in the same section, and the installation section of the corrugated steel ...

Abstract

The invention relates to a corrugated steel web bridge stepped construction technology. The technology is divided into an N segment, an N+1 segment and an N+2 segment in the longitudinal direction of a bridge according to construction segment orders. In each segment, a top plate is arranged on the upper portion, a bottom plate is arranged on the lower portion, and a corrugated steel web is located between the top plate and the bottom plate. Operation of three segments includes the steps that 1, the top plate is constructed on the N segment, and the bottom plate is constructed on the N+1 segment; 2, the corrugated steel web is installed on the N+2 segment; 3, after operation of three segments is completed, the three segments respectively enter the next segments in sequence. The corrugated steel web bridge stepped construction technology enables the top plates, the bottom plates and the corrugated steel webs to be constructed in a staggered mode, no crossing exists among working procedures, the working procedures do not influence mutually, and potential safety hazards existing in construction are eliminated. Three working faces can be constructed at the same time and synchronous completion is basically achieved. The problems of idling of labor force during equal strength and insufficient staff in the next segment construction are avoided, the effect that manpower resources are reasonably allocated in the time axis is achieved, thus a construction period is shortened by more than 35%, and construction cost is saved.

Description

technical field [0001] The invention relates to a bridge construction technology, in particular to a stepped construction technology of a corrugated steel web bridge. Background technique [0002] With the continuous development of bridge structures in our country, new bridge structures are constantly emerging, and corrugated steel web bridges, as a new structure, are being gradually applied. During the construction of ordinary corrugated steel web bridges, the top and bottom slabs are poured simultaneously, and a large amount of work is concentrated in the same segment. Since the top plate and the bottom plate are operated simultaneously in the up and down direction, it will be difficult to find a suitable support point for the top plate formwork. However, the base plate is constructed simultaneously below the roof plate, which is easily affected by the construction of the roof plate above, and there are certain potential safety hazards. Contents of the invention [000...
