Description
Technical field
The utility model is related to a kind of strengthen and interlocking for country rock defective section tunnel antidetonation shock attenuation ability sets seam liner structure, relates to
And mountain tunnel and Construction Technique of Underground Works, exist just especially for the highlight lines such as Wenchuan, cajaput strong earthquake area domain country rock
The geology location of beginning defect (cavity, leakiness situation), belongs to high-intensity earthquake Mountain Tunnels and underground engineering field.
Background technology
During Soft Rock Tunnel, easily there is Lining cracks, infiltration in such as construction wrong, and just branch invades limit or even causes to collapse
Square accident.After cave in accident, landslide body should be cleared up in time, backfill the chamber that collapses, and grouting and reinforcing is carried out to backfill body.But no matter take
Which kind of back-filling way, backfilling material, injecting paste material and grouting amount, the parameter such as intensity, rigidity, joint, the occurrence of intracavitary of collapsing country rock
It can not all recover to former state of surrounding rock, this has also resulted in the increase of country rock rejected region Earthquake Inertia Force Acting, Internal force of support structure increases
Greatly, so occur Lining cracks, fall it is fast, or even lining cutting collapse earthquake.
Utility model content
Technical problem to be solved in the utility model there is provided a kind of easy construction, economical and practical enhancing country rock lacks
That falls into section tunnel antidetonation shock attenuation ability staggeredly sets seam liner structure, and can effectively reducing earthquake wave direction tunnel, longitudinally transmission causes lining
Build structure destruction.
The utility model is adopted the following technical scheme that：
A kind of strengthen sets seam liner structure interlocking for country rock defective section tunnel antidetonation shock attenuation ability, and it includes being arranged on tunnel
It is equidistant along tunnel depth direction in preliminary bracing on inwall and the secondary lining being covered in preliminary bracing, the preliminary bracing
It is provided with ring absorbing joint in preliminary bracing, the secondary lining along tunnel depth direction and has been placed equidistant secondary lining inner ring
To absorbing joint, ring absorbing joint is interspersed in ring absorbing joint and secondary lining in the preliminary bracing.
Further, it is filled with tar sand in the preliminary bracing in ring absorbing joint and secondary lining in ring absorbing joint
Mix.
Further, buried rubber fastening band during the centre position of ring absorbing joint is set in the secondary lining, it is described
The backwater of ring absorbing joint in back-adhering waterstop, the secondary lining is set in secondary lining on the upstream face of ring absorbing joint
Caulking compounds are filled with face.
Further, also it is equipped with splash guard between the preliminary bracing and secondary lining.
Further, in each described preliminary bracing between ring absorbing joint and each described secondary lining in ring damping
Length of the interval equal to lining trolley between ring absorbing joint in same interval, each described described preliminary bracing is taken between seam
Degree.
The beneficial effects of the utility model are as follows：
The utility model is by being arranged at the ring absorbing joint of preliminary bracing and secondary lining, by ring absorbing joint along tunnel
Longitudinally spaced ring absorbing joint between arrangement, and preliminary bracing and secondary lining is misaligned, that is, is staggered, can effectively carry
High water resistance, can effectively strengthen tunnel antidetonation shock attenuation ability, it is possible to use lining trolley applies secondary lining and left in itself again
Seam be used as ring absorbing joint so that the difficulty of construction of ring absorbing joint is small, cost is low.
The ring absorbing joint set in preliminary bracing uses filled bitumen sand mix filling in seam, while two lining lining cutting
Ring absorbing joint also filled bitumen sand mix, tunnel is further increased with strong and good endurance the advantage of its non-deformability
Error resilience cutting capacity, reaches the function of weakening or block earthquake wave direction tunnel longitudinal propagation path under geological process.
Ring absorbing joint in two lining lining cutting is together applied with two lining waterproofs, buried rubber fastening band and back sticking type in burying
Waterstop, is stretched to adapt to concrete deformation with the elasticity and structure type of its elastomeric material, can effectively prevent oozing for component
Water, leak, can also play a part of damping, buffering while fit sealing.
Caulking compounds are filled with secondary lining on the back side of ring absorbing joint, are further improved at water resistance and gap
Flatness.
Splash guard is also equipped between preliminary bracing and secondary lining, water resistance is further improved.
Taken in each described preliminary bracing between ring absorbing joint and in each described secondary lining between ring absorbing joint
Length of the interval equal to lining trolley in same interval, each described described preliminary bracing between ring absorbing joint, using lining
When platform building cart applies secondary lining, the seam itself left is typically consistent with vehicle commander, using applying one section of secondary lining all every time
The seam that can be left reduces construction volume as ring absorbing joint, reduces difficulty of construction and construction cost.
The utility model structure can effectively reduce earthquake wave direction tunnel, and longitudinally transmission causes liner structure to destroy, and reduces ground
Casualty loss is shaken, tunnel operation security is ensured.
