Problems solved by technology

[0003] The present invention aims at the disadvantages of corrugated steel plates in the prior art that the underground steel plate structure is connected by more corrugated steel webs, which reduces the stiffness of the arched tunnel, requires a large amount of engineering construction, and has poor waterproof effect, etc., and provides each The cross section is only connected by one or two corrugated steel webs, and the corrugated steel webs are connected by an effective waterproof connection device, which is convenient for installation, reduces the construction amount of the project, and improves the arch tunnel structure. Corrugated steel web reinforced concrete tunnels and underground structural units with excellent strength and waterproof performance

Abstract

The invention relates to a steel web reinforced concrete structure, and discloses a corrugated steel web reinforced concrete tunnel and an underground structural unit applied to various traffic tunnels and underground reinforced concrete structures, comprising a reinforced concrete base and corrugated steel web camber units arranged on the reinforced concrete base, wherein each corrugated steel web camber unit is of an arch shape, and consists of one or two circular arc corrugated steel webs, adjacent corrugated steel web beam units are connected through a water-proof connection device, a steel plate is connected with one end of the corrugated steel web that is connected with the reinforced concrete base, and is welded with fastening screws. In the invention, the structural unit only adopts one or two corrugated steel webs which are connected through the effective water-proof connection device, facilitates installation, reduces construction amount, and increases the structural intensity and water-proof performance of arc tunnels.

Description

technical field [0001] The invention relates to a corrugated steel web reinforced concrete structure, in particular to a corrugated steel web reinforced concrete tunnel and an underground structural unit applied to various traffic tunnels and underground reinforced concrete structures. Background technique [0002] The key part of the traditional corrugated steel web reinforced concrete composite structure tunnel: the corrugated steel web and the cross section are composed of multiple corrugated steel webs, and the common connection method is adopted. Due to the limited length of the corrugated steel web, a transverse The number of corrugated steel webs used on the surface is too much. For example, the invention patent No. 200410086448.6 applied by Hirayama SI Co., Ltd., the application date is October 20, 2004, and the announcement date is April 26, 2006. The announcement number is CN1763319, the name is the underground steel plate structure using corrugated steel plate and...
