Semi-circular confluence regulation and storage type deep layer tunnel built through shield tunneling machine

Abstract

A semi-circular confluence regulation and storage type deep layer tunnel built through a shield tunneling machine comprises a semi-circular outer shell, a compartment body, a rainwater pipe, a waste water pipe, a rainwater pipe abutment, a waste water pipe abutment, an overhaul lane with a water leakage urgent storage compartment, a ventilating and lighting system, an overhaul platform with a water leakage urgent storage compartment and the like; the semi-circular confluence regulation and storage type deep layer tunnel built through the shield tunneling machine is divided into a semi-circular confluence regulation and storage type deep layer tunnel body built through the shield tunneling machine of a single waste water pipe and a semi-circular confluence regulation and storage type deep layer tunnel body built through the shield tunneling machine of double waste water pipes, the semi-circular outer shell is made of water-proof concrete, and the inner layer and the outer layer are separately provided with a leakage-proof coating; and the ventilating and lighting system is installed in the middle of the top of the inner side of the semi-circular outer shell. The semi-circular confluence regulation and storage type deep layer tunnel built through the shield tunneling machine has the beneficial effects that rainwater is effectively separated from waste water, and thus water pollution is prevented to the greatest extent; and efficient, reliable and safe maintaining system and space are ensured, and the space using rate is increased.

Description

technical field [0001] The invention relates to deep tunnel technology, in particular to a confluence storage type deep tunnel constructed by a semicircular 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 deep tunnel engineering to ...

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
