Abstract

The invention discloses an assembly-type tunnel joint form and relates to the technical field of traffic and transportation. A joint steel lantern ring is arranged on the outer wall of a tunnel structure inserting end. A first sealing rubber ring and a second sealing rubber ring are arranged on the outer wall of a tunnel structure bell end. An elastic sealing gasket is arranged on the end face of the tunnel structure inserting end. A steel ring is arranged on the outer wall of an end opening of the tunnel structure bell end. An injection pipe is arranged in the tunnel structure inserting end. A shear resistant plug pin and a plug pin hole are arranged at the tunnel structure inserting end and the tunnel structure bell end. The tunnel structure inserting end and the tunnel structure bell end are connected in an inserting mode through the shear resistant plug pin and the plug pin hole. The assembly-type tunnel joint form is small in joint manufacturing difficulty, convenient to mount, fast, low in cost, good in waterproof effect, safe and reliable. A joint structure has certain rigidity, so that in a complex stratum, the influence of uneven settlement on a tunnel can be resisted.

Description

technical field [0001] The invention relates to the technical field of transportation, in particular to an assembled tunnel joint form. Background technique [0002] At this stage, my country's urbanization is in a period of rapid development, with the continuous transformation and expansion of megacities and megacities, and the rapid development of small and medium-sized cities. The size and structure of cities are undergoing great changes. While the development of modern transportation has brought convenience to people, it has also brought negative impacts: with the increase of cars, congestion has become a common problem in large and medium-sized cities. How to increase the road traffic capacity in the limited space of the city is an urgent problem to be solved in many cities. Since tunnels are laid under existing roads or urban rivers, they have little impact on ground traffic or river waterways, and are increasingly used in the expansion of urban road traffic capacity...
