Embodiment Construction

[0026] The embodiments of the present invention are described in detail below with reference to the accompanying drawings, but the present invention can be implemented in many different ways as defined and covered by the claims.

[0027] refer to figure 1 , the preferred embodiment of the present invention provides a trestle bridge structure, comprising: a support beam frame 10 erected along the extension direction of the trestle, the support beam frame 10 is laid with a support panel extending along its length direction for supporting people or vehicles 20. A plurality of groups of pier column vertical frames 30 are supported below the support beam frame 10 for jointly supporting it. The bottom of each pier column stand 30 is supported with a trestle foundation 40 as the foundation supported by the trestle, and the trestle foundation 40 includes a trestle pile foundation constructed by on-site construction and a plurality of miniature ground piles 41 embedded in the undergrou...

Abstract

The invention discloses a trestle structure and a construction method thereof. The trestle structure includes a supporting beam frame, a supporting panel is laid on the supporting beam frame, the lower part of the supporting beam frame is provided with a plurality of groups of pier column vertical frames for supporting the supporting beam frame together, and the groups of pier column vertical frames are successively distributed at intervals in the length direction of the supporting beam frame; and the lower parts of the pier column vertical frames are provided with a trestle foundation used asa supporting foundation, the trestle foundation includes a trestle pile foundation built by a plurality of miniature pegs which are constructed on site and embedded in an underground rock stratum anda supporting base platform supported on the trestle pile foundation, and the pier column vertical frames are supported on the corresponding arranged supporting base platform. According to the trestlestructure, according to the actual construction needs, the heights of the pier column vertical frames are adjusted, and then the height of a trestle is adjusted; and by adjusting the supporting widths of the pier column vertical frames and / or adjusting a layout mode of the miniature pegs, the supporting width of the trestle pile foundation can be adjusted, different requirements of stress and deformation are met by adjusting the length of the trestle pile foundation, and the application range is wide.

Description

technical field [0001] The invention relates to the field of traffic engineering construction, in particular to a trestle bridge structure. In addition, the present invention also relates to a construction method of a trestle bridge. Background technique [0002] During the construction of traffic engineering, especially the construction of the existing road project, it is necessary to ensure the normal operation and safety of the existing road, and the construction of temporary trestle is one of the most commonly used methods. The existing trestle has the following problems: the structure of the trestle is complex, the cost is high, the construction efficiency is low, and the scope of application is small. Under the condition of short construction period and limited construction site, how to solve the construction of temporary trestle quickly, easily and with high quality is a very important problem in traffic engineering construction. In addition, in the existing constru...
