Description

technical field

[0001] The invention relates to the technical field of road and railway tunnel safety construction, in particular to a multifunctional connection device for a tunnel escape pipeline. Background technique

[0002] The construction of highway tunnels in my country started relatively late. Compared with foreign developed countries, the relevant technical level is still relatively low. In addition, the characteristics of highway tunnels, such as large spans, complex construction techniques, and variable terrain, lead to many technical problems in the process of highway tunnel construction. Although the new Austrian construction technology of highway tunnels in our country has become more and more mature, and the relevant design theory and construction technology of tunnels with complex geological conditions have achieved certain results, collapse accidents have occurred frequently during tunnel construction, and construction safety problems are extremely serious. ...
