Present in Highway Tunnel in Loess work progress, a big technical barrier is how to better control over surrouding rock deformation, therefore at present
It is accomplished by preliminary bracing structure and there is enough intensity and preferable stability.In order to strengthen Highway Tunnel in Loess preliminary bracing structure
Stability, the general supporting type using shaped steel arch to coordinate vertical equity dowel.Traditional longitudinally connected mode uses vertical
Connecting two adjacent Pin shaped steel archs to the dowel of a plurality of level, this kind of method of attachment shortcoming is parallel longitudinal dowel and type
The quadrilateral structure formed between steel arch-shelf is unstable, is unfavorable for controlling the large deformation of loess tunnel, there is bigger potential safety hazard.
Utility model content
The weak point existed for above-mentioned prior art, this utility model provides that a kind of stability is strong, be easy to processing and peace
Fill convenient Tunnel shaped steel arch attachment means vertical equity dowel.
For achieving the above object, this utility model adopts the following technical scheme that
A kind of Tunnel shaped steel arch attachment means, including adjacent two Pin shaped steel archs and be arranged on adjacent two Pin shaped steel
Vertical equity dowel between bow member, it is characterised in that: described adjacent two Pin shaped steel archs all include top girth and bottom
The edge of a wing；It is additionally provided with on the top girth of described adjacent two Pin shaped steel archs and/or bottom flange and connects adjacent two Pin shaped steel archs
Oblique dowel；Described vertical equity dowel, oblique dowel and shaped steel arch structure triangular in shape.
As preferably, the angle between oblique dowel and vertical equity dowel that this utility model is used is 45 °.
As preferably, the oblique dowel that this utility model is used and vertical equity dowel are isometrical.
As preferably, the oblique dowel that this utility model is used is all 22mm or 25mm with the diameter of vertical equity dowel.
As preferably, the company of being provided with on the top girth of the adjacent two Pin shaped steel archs that this utility model is used and bottom flange
When connecing the oblique dowel of adjacent two Pin shaped steel archs, the oblique dowel of the top girth of the adjacent two Pin shaped steel archs of described connection
The spatially interleaved setting of oblique dowel with the bottom flange connecting adjacent two Pin shaped steel archs.
Vertical equity dowel vertical equity dowel vertical equity dowel vertical equity dowel
As above technical scheme is used to have a following superiority:
This utility model one Tunnel shaped steel arch attachment means, be Highway Tunnel in Loess shaped steel arch splicing and by
After the spacing of 50cm sets up, between adjacent two Pin shaped steel arch, it is spaced 50cm a number of vertical equity dowel is set,
And add oblique dowel between the adjacent two vertical equity dowels of shaped steel arch edge of a wing homonymy so that vertical equity dowel
And between oblique dowel and shaped steel arch, form triangle rock-steady structure.This utility model is by adjacent two Pin shaped steel archs
With arranging oblique connection reinforcing bar on side wing edge, effectively solve preliminary bracing shaped steel arch longitudinal stability in Conventional attachment methods
The problem of difference, it is ensured that the longitudinal stability between adjacent two Pin shaped steel archs, is conducive to controlling loess tunnel because of enclosing that excavation causes
Rock large deformation, greatly reduces construction risk, is particularly suitable for during loess tunnel especially Q3 and Q4 loess tunnel construction
Use.
