Rail transit engineering shallow-buried interval prefabricated laminated structure and construction method thereof

Abstract

The invention provides a rail transit engineering shallow-buried interval prefabricated laminated structure and a construction method thereof, and relates to the field of rail transit construction. The rail transit engineering shallow-buried interval prefabricated laminated structure comprises a box culvert and prefabricated piles distributed on the two sides of the box culvert, and first longitudinal ribs inside the prefabricated piles and second longitudinal ribs in the box culvert are jointly matched with cylindrical spiral linear connecting ribs; and in the spiral structures of the connecting ribs, first transverse ribs distributed perpendicular to the first longitudinal ribs are arranged on the sides, away from the second longitudinal ribs, of the first longitudinal ribs, and second transverse ribs distributed perpendicular to the second longitudinal ribs are arranged on the sides, away from the first longitudinal ribs, of the second longitudinal ribs. The enclosure structure andinterval main body structure are prefabricated in an industrialized mode, the temporary enclosure structure can serve as a permanent structure to be combined with the box culvert after enclosure workis completed, permanent and temporary overlapping of the prefabricated square pile enclosure and the interval main body is achieved, the side wall thickness of the box culvert main body structure canbe reduced while the supporting strength is met, and the construction speed is increased.

Description

technical field [0001] The present disclosure relates to the field of rail transit construction, in particular to a prefabricated composite structure and a construction method for a shallow buried section of a rail transit project. Background technique [0002] The statements in this section merely provide background information related to the present disclosure and may not necessarily constitute prior art. [0003] With the rapid development of basic transportation, urban rail transit projects have become the leading force in the development of public transportation. In the section where the line laying method is shallow buried or super shallow buried, the open cut method is usually used for construction, and the existing construction method generally adopts cast-in-place reinforced concrete structure or prefabricated box culvert assembly structure. [0004] The inventors found that currently, in the construction of cast-in-place concrete structures, it is necessary to car...

AI Technical Summary

Problems solved by technology

[0004] The inventors found that currently, in the construction of cast-in-place concrete structures, it is necessary to carry out processes such as base cushion construction, on-site laying and binding of steel bars, erecting formwork, concrete pouring and vibration, maintenance, and formwork removal. The construction procedures are cumbersome and labor-intensive , the construction period is long, and its environmental protection is poor; when carrying out the construction of prefabricated box culvert assembly structures, the construction procedure is generally to make bored piles as the enclosure structure, and excavate the foundation pit after the concrete curing reaches the design strength After the excavation of the foundation pit is completed, it will be used as a cushion, and the prefabricated box culvert assembly construction will be carried out

The disadvantages are that the quality of bored piles is difficult to guarantee, and the problems of diameter shrinkage and mud inclusion are prone to occur. The construction will cause certain pollution to the environment, and it will take a long time to wait for the strength of the age. Abandoned after the box culvert is completed, resulting in a serious waste of resources, which is not conducive to sustainable development
