在上海修建地下铁道采用隧道高气压方法,施工前,我们预先设计了隧道高气压作业减压表(以下简称减压表)和重复高气压作业减压表(以下称重复减压表)并做了实验,以供本工程隧道高气压作业时减压用。本文目的是介绍减压表的减压特点
Before the construction of tunnels in Shanghai, we designed a tunnel decompression gauge (hereinafter referred to as decompression gauge) and a repetitive high pressure decompression gauge (hereinafter referred to as the duplication decompression gauge) and made Experiment, for the project of high pressure air pressure tunnel operation. The purpose of this article is to introduce the decompression features decompression table
