Merge storage type deep tunnel constructed by three-circle overlapping shield machine

Abstract

A three-circle erecting confluence regulation and storage type deep tunnel built by a shield tunneling machine comprises a three-circle-shaped deep tunnel shell, vertically stressed partition walls, an upper layer lane base plate, rainwater compartments, a sewage compartment, a repair compartment, an upper layer ventilation and lighting system, a lower layer ventilation and lighting system, a sewage pipe abutment, a sewage pipe, a maintenance platform, leakage water emergency storage compartments, a climbing ladder, an upper and lower layer in-out opening and maintenance lanes. The three-circle deep tunnel shell and the vertically stressed partition walls are all made from waterproof cement. The vertically stressed partition walls divide the tunnel into the three compartments. The compartments at the two ends are the rainwater compartments. The upper layer lane base plate is arranged in the middle in the middle compartment and divides the middle compartment into the upper compartment and the lower compartment. The upper compartment is the sewage compartment, and the lower compartment is the repair compartment. One end of the upper layer lane base plate is provided with the upper and lower layer in-out opening. By adoption of the three-circle erecting confluence regulation and storage type deep tunnel, rainwater and sewage are effectively separated, water body pollution is prevented, a repair system and a pace which are efficient, reliable and safe are ensured, and the space utilization rate is increased.

Description

technical field [0001] The invention relates to deep tunnel technology, in particular to a confluence regulation and storage type deep tunnel constructed by a three-circle overlapping shield machine. Background technique [0002] Deep storage tunnels refer to large and extra-large drainage tunnels buried in deep underground spaces (generally referring to spaces with a depth greater than 20m below the ground). Generally, in areas prone to waterlogging, densely populated, complex underground pipelines, and difficult to transform existing drainage systems, deep storage tunnels can be set up. The use of large-scale deep storage tunnels supplemented by source runoff control is to implement the construction requirements of the "sponge city" and reflect the water control strategy that is tailored to water conditions and local conditions. It is also a common practice in foreign countries to improve drainage and waterlogging prevention standards in established areas. [0003] Using ...

AI Technical Summary

Problems solved by technology

[0005] However, the use of these confluence storage type deep tunnel system projects requires high maintenance and management costs, or low utilization rate, so it is necessary to develop a confluence storage type deep tunnel that is easy to maintain and can use space efficiently
