Construction method for providing shear bearing capacity for gapped discrete steel structure tube bundle

Abstract

The invention discloses a construction method for providing shear bearing capacity for a gapped discrete steel structure tube bundle. The method comprises the following steps of: 1, manufacturing a steel tube section outer flange, a steel tube section inner flange and a steel tube section web plate, and forming a corrugated tube through hole in the steel tube section web plate; 2, manufacturing of a first clamping piece and a second clamping piece is completed, the first clamping piece and the second clamping piece are fixed to the steel pipe joint outer flange and the steel pipe joint inner flange correspondingly, and the first clamping piece and the second clamping piece are arranged in the jacking direction in a full-length mode; and 3, the steel pipe joint web plates are fixed to the steel pipe joint outer flanges and the steel pipe joint inner flanges correspondingly, and whole manufacturing of the steel pipe joint is completed. The shear resistance problem of the transverse stress steel pipe row is solved, the non-filling concrete pipe curtain structure becomes possible, the construction means of underground engineering is expanded, the industrial technical progress is promoted, and good economic and social benefits are achieved.

Description

technical field [0001] The invention relates to the technical field of pipe curtain structures, in particular to a construction method for providing shear bearing capacity for discrete steel structure pipe rows with gaps. Background technique [0002] With the rapid development of my country's economy and the continuous increase of population density, there are fewer and fewer ground resources that can be developed, and the land utilization rate has become saturated. Therefore, the development of cities into underground space is an inevitable trend of the development of international metropolises. However, when building underground structures in urban core areas and old urban areas, there will be problems such as insufficient underground space and inaccessible adjacent facilities. [0003] The existing underground excavation method in this field has gradually become the preferred method for building underground structures in complex environments due to its advantages of les...

Problems solved by technology

However, this will not only prolong the construction period and increase the cost, but also increase the difficulty and risk of construction; at the same time, because most of the pipe curtain structure is longitudinally stressed, the shear bearing capacity of the transverse pipe joints and the locks between pipe joints is low. is smaller
