Combined storage storage type deep tunnel constructed by horseshoe shield machine

Abstract

A confluence regulation and storage type deep tunnel constructed through a horseshoe shield machine comprises a horseshoe outer shell, a rainwater bin, a sewage and overhaul sub-bin, a sewage pipe, an overhaul cart, an arc separating plate, an overhaul lane, a sewage pipe basket, horizontal plate sections, bearing plates, a rainwater bin lane, a leaking water emergency storage bin and a ventilation system. The confluence regulation and storage type deep tunnel constructed through the horseshoe shield machine is excavated through the horseshoe shield machine and formed in a lining mode. The horseshoe outer shell has a horseshoe section, the interior of the horseshoe outer shell defines a whole cavity, and the arc separating plate is arranged in the horseshoe outer shell. The horizontal plate sections are arranged on two sides of the arc separating plate correspondingly and fixedly connected with the bearing plates. The arc separating plate and the horizontal plate sections divide the whole cavity into an upper bin and a lower bin, the lower bin is the rainwater bin, and the upper bin is the sewage and overhaul sub-bin. According to the confluence regulation and storage type deep tunnel constructed through the horseshoe shield machine, 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 the deep tunnel technology, in particular to a confluence regulation and storage type deep tunnel constructed by a horseshoe-shaped 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...

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
