Problems solved by technology

But this method will have the following problems, the lower tunnel must be constructed first, if the upper tunnel has been constructed to the intersection node, but the lower tunnel has not been completed, the upper tunnel needs to be shut down, and the construction of the lower tunnel will be resumed after the node is completed; at the same time, the upper and lower tunnels Large height difference often leads to poor tunnel alignment

Abstract

The invention is applicable to the technical field of municipal engineering, and provides an intersection tunnel joint building structure and a construction method thereof. The intersection tunnel joint building structure is provided with an upper-layer tunnel, a lower-layer tunnel and a single-hole double-layer joint building section structure, wherein the upper-layer tunnel and the lower-layer tunnel are crossed in a plane, and the joint building section structure is located at a crossed position between the upper-layer tunnel and the lower-layer tunnel; the middle position of the joint building section structure in the vertical direction is separated by a middle plate, and a space above the middle plate is used for allowing vehicles at the upper-layer tunnel to pass; and a space below the middle plate is used for allowing vehicles at the lower-layer tunnel to pass. Through the structure, the vertical height difference between the upper-layer tunnel and the lower-layer tunnel can becompressed to limitation, and the road line type is optimized; and meanwhile, the construction method can start construction from any tunnel face arriving at a crossed node in advance, the down time problem caused by the fact that the construction progress of the upper-layer tunnel and the lower-layer tunnel are different is avoided, the construction period is effectively shortened, the implementation performance is high, the construction cost is low, and the intersection tunnel joint building structure is worthy of wide popularization.

Description

technical field [0001] The invention belongs to the technical field of municipal engineering, and in particular relates to a joint construction structure of intersecting tunnels and a construction method thereof. Background technique [0002] With the rapid rise of urban underground roads, underground interchanges are becoming more and more common. Underground interchanges are generally equipped with multiple ramps, and there is an unavoidable crossing relationship between the ramp and the main line or between the ramp and the ramp. The tunnels crossing up and down are generally constructed separately. During construction, the lower tunnel is generally constructed first, and the upper tunnel is constructed later. The clear distance between the upper and lower tunnels is generally not less than 4m. The larger the tunnel span, the greater the clear distance, so as to reduce the impact of the upper tunnel constructed later on the lower tunnel constructed earlier and ensure the...
