Sectional Beam Field Structure with Retaining Wall and Its Construction Method

Abstract

The invention provides a retaining wall partitioned beam field structure and a construction method thereof. The beam field structure includes: a beam storage area, and the beam storage area forms a first beam field roadbed with a first slope in the form of excavation and filling The beam lifting area is adjacent to the beam storage area, and the beam lifting area forms the second beam field subgrade of the second slope in the form of excavation and filling; the partition retaining wall is arranged between the beam storage area and the beam storage area. Between the lifting beam areas; two track retaining walls for the installation and walking of the gantry crane, which are arranged in the beam lifting area and respectively connected to the two ends of the partition retaining walls. The present invention separates the beam storage area from the beam lifting area by building partition retaining walls and combines excavation and filling to realize the divisional reduction of the use slope of the beam field functional area, and realizes the organic combination of the beam field functional area and the site terrain; the partition retaining wall The setting of the track can reduce the slope and improve the land utilization rate of the beam yard; the setting of the track retaining wall can easily adjust the walking slope and walking elevation of the gantry crane.

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, environmental protection requirements 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 prefabricated beams are constructed outside the work area. Field plan is not feasible. In addition...

AI Technical Summary

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
