Abstract

The invention provides a stepping stair section channel for underground deep large engineering construction and aconstruction method thereof, and belongs to the technical field of underground engineering construction channels. The stepping stair section channel is characterized in that the stepping stair section channel comprises vertical stand column supporting frames, transverse pulling-connection parts and platform beams, the verticalstand column supporting frames comprise vertical square pipe stand columns (1) and positioning steel plates (2) fixedly connected with the bottoms of the square pipe stand columns (1) and pre-buried underground, and inserting pieces are arranged at the tops of the square pipe stand columns (1); and vertical multi-layer inserting assembling is formed throughthe inserting pieces, the square pipe stand columns (1) are transversely connected with longitudinal horizontal pulling rods (7), the multiple vertically-parallelly-arranged platform beams are mounted, oblique beams are arranged between the adjacent platform beams, and stair sections (17) are mounted through the oblique beams. The stepping stair section channel is suitable for underground deep large engineering with a narrow construction site and a small geosyncline foundation excavation work face, substitutes a traditional simple oblique-type steel pipe buckle ladder stand, and can meet on-duty and off-duty passing of two strands of people streams, personnel is unblocked, and safety and reliability are achieved.

Description

technical field [0001] The invention relates to an underground deep engineering construction stepping stair passage and a construction method thereof, which belong to the technical field of underground engineering construction passages. Background technique [0002] At present, the level of green science and technology in my country is constantly improving, which puts forward higher requirements for the production capacity and technical level of the construction industry. In order to save land resources to the greatest extent, construction projects are gradually extended to the underground space. Subsequently, there are more and more deep foundation pit projects, the amount of underground projects has doubled, and the construction period has been extended accordingly. The traditional simple steel pipe fastener type ladder channel is no longer suitable for underground engineering construction. The "Right Triangular Passage for Stepped Stair Sections of Underground Deep and L...
