Description
Technical field
The utility model belongs to technical field of tunnel construction, passes through the inverse rich water richness sand that rushes of high angle more particularly, to one kind and breaks
Layer tunnel excavation constructing structure.
Background technique
Fault belt refers to two disk relative motion of tomography, and mutual extrusion makes neighbouring catalase, formation and fault plane
Substantially parallel crushed zone, abbreviation fracture belt.At home, high angle reversed fault of the section dip angle greater than 45 ° or 30 ° is known as inverse punching
Tomography, the constructing tunnel difficulty for passing through high angle thrust is very big, and above-mentioned high angle thrust refers to that section dip angle is greater than
60 ° of thrust.Especially when locating stratum is rich water richness Flooding in Borehole, difficulty of construction is bigger.Rich water richness Flooding in Borehole is also referred to as
For rich water Flooding in Borehole, refers to and be rich in underground water in stratum and contain layer of sand, which is both water rich strata, is also rich Flooding in Borehole.
In rich water richness Flooding in Borehole, rock crushing provides more favorable condition for the preservation of underground water and enrichment, and difficulty of construction is very big,
In addition containing layer of sand in stratum, Sand easily occurs in construction, along with tomography section dip angle is greater than 60 °, easily causes calamity
Difficulty consequence, seriously affects construction safety and benefit.Thus, when being rich in underground water in Tunnel Passing tomography, rock mass is mostly broken

To when passing through the inverse tunnel for rushing rich water richness sand tomography of high angle and excavating, need to be excavated using benching tunnelling method.Platform
Rank method refers to first tunneling top section (top bar), starts to excavate (the leave from office of lower part section after the advanced certain distance of top bar
Rank, also referred to as tunnel top hole body), the construction method that up/down steps are gone forward side by side simultaneously.Wherein, three bench cut methods (also referred to as three
Rank method) refer to that institute's tunneling, which is divided into the step of upper, middle and lower three, excavates.It is rich to high angle is passed through using three benching tunnelling methods
When the tunnel of water thrust is excavated, since excavated section piecemeal is more, difficulty of construction is big and construction risk is high, it is necessary in time
Reasonable support construction is set, on the one hand prevents subsequent excavation region from collapsing, is on the other hand had to having excavated molding hole body
Supporting is imitated, to ensure construction safety.
