Combined storage storage type deep tunnel constructed by similar rectangular shield machine

Abstract

Disclosed is a confluence regulation and storage type deep tunnel constructed through a rectangle-like shield machine. The confluence regulation and storage type deep tunnel constructed through the rectangle-like shield machine is excavated through the rectangle-like shield machine and formed in a lining mode. The bin wall of the deep tunnel has a rectangle-like section. A rainwater bin and a sewage bin are arranged on the left side and the right side correspondingly and each have a round or square-like section, preferably the square-like section. Water bin abutments are arranged on the lower portions of the rainwater bin and the sewage bin, a vehicle traveling overhaul passage is arranged between the rainwater bin and the sewage bin, and pedestrian overhaul passages are arranged on two sides correspondingly. The confluence regulation and storage type deep tunnel constructed through the rectangle-like shield machine has the beneficial effects that rainwater and sewage are effectively separated, water pollution is prevented to the maximum extent, an efficient, reliable and safe repair system and repair space are guaranteed, and the space utilization rate is improved.

Description

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

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
