Retaining wall partition-type beam fabricating yard structure and construction method thereof

Abstract

The invention provides a retaining wall partition-type beam fabricating yard structure and a construction method thereof. The beam fabricating yard structure comprises a beam fabricating and storage area, a beam lifting area, a partition retaining wall and two track retaining walls for installation and traveling of a gantry crane, wherein a first beam fabricating yard subgrade with a first slope is formed in the form of excavation and filling in the beam fabricating and storage area; the beam lifting area is arranged adjacent to the beam fabricating and storage area, and a second beam fabricating yard subgrade with a second slope is formed in the form of excavation and filling in the beam lifting area; the partition retaining wall is arranged between the beam fabricating and storage area and the beam lifting area; and the track retaining walls are arranged in the beam lifting area and correspondingly connected with the two ends of the partition retaining wall. According to the beam fabricating yard structure, the partition retaining wall is built to separate the beam fabricating and storage area from the beam lifting area, the use slope of a beam fabricating yard functional area isreduced by partition in combination with excavation and filling, and the organic combination of the beam fabricating yard functional area and the site topography is achieved; grading can be reduced by arranging the partition retaining wall, and the land utilization rate of a beam fabricating yard is increased; and the traveling slope and the traveling elevation of the gantry crane can be conveniently adjusted by arranging the track retaining walls.

Description

technical field [0001] The invention relates to the technical field of building construction, in particular to a retaining wall partitioned beam field structure and a construction method thereof. Background technique [0002] Most of the prefabricated girder yards are set in the yard area near the straight section of the bridge or the gentle subgrade section of the bridge head. The slope of the gantry crane traveling track and the slope of the girder yard functional area are in a horizontal state. This scheme is not suitable for steep or curved road sections. In mountainous water source protection areas, the requirements for environmental protection and water protection are high, and there is a lack of large flat sites. The cost of land acquisition outside the red line is high, the cost of later reclamation is high, and the construction of access roads for transporting beams is difficult and expensive, so the construction site is selected outside the work area. The scheme of...

Problems solved by technology

[0005] (1) Multiple grading of the beam field will reduce the utilization rate of the beam storage area, limit the number of beam storage pedestals, and directly restrict the construction progress of the prefabricated beam. Each grading area is an independent functional area, which cannot achieve the same Complementary Sharing of Adjacent Hierarchical Areas

[0006] (2) Affected by the multiple classifications of the beam field, the water pipe layout, line layout, drainage system layout and traffic guidance in the beam storage area are limited, and the adjustment range of the longitudinal slope of the track is also restricted
