With.Skilled worker's welding technique is uneven, when not prison welding, and the locking angle does not become entirety with steelframe, is controlled by the locking angle
Vault sinking and horizontal convergence DeGrain processed.
Utility model content
For the disadvantages described above or Improvement requirement of prior art, the utility model is connected there is provided a kind of Tunnel Engineering locking angle
Device, reduces workman's welding technique level to lock pin steel pipe and the influence of steelframe globality, pin steel pipe functioning efficiency is locked improving
While can also control vault sinking and horizontal convergence to greatest extent.
To achieve the above object, according to the utility model there is provided a kind of Tunnel Engineering locking angle attachment means, its feature exists
In, including I-steel, U-shaped spiral, connection sleeve pipe and lock pin steel pipe, wherein,
The I-steel includes riser and two transverse slats, and two transverse slats are separately positioned on up and down the two of the riser
Through hole is provided through on end, the riser；
The U-shaped spiral passes through the riser from the through hole on the riser, and it includes middle overstriking section and two
Fastener for connection section, wherein, two fastener for connection sections are separately positioned on the both sides of the middle overstriking section, the middle overstriking
The first thread segment is provided with section, each described one end of fastener for connection section away from the middle overstriking section is provided with the second spiral shell
Two nuts are threaded with line section, first thread segment, and the riser, Mei Gesuo are clamped in the cooperation of the two nuts
State and the connection sleeve pipe is all connected with the second thread segment, each one end of the connection sleeve pipe away from first linkage section connects
Connect the lock pin steel pipe.
Preferably, the U-shaped spiral welds together at the position of the riser through hole with the riser.
Preferably, each it is provided with packing ring between the nut and the riser.
In general, by the contemplated above technical scheme of the utility model compared with prior art, it can obtain down
Row beneficial effect：
The utility model can effectively reduce the influence of construction technology level and skilled worker's weld horizontal, reduce weak surrounding rock
Location differential settlement influence, ensures steelframe and surrounding country rock one entirety of formation, control vault sinking and water to greatest extent
Flat convergence, so that reducing the later stage carries out excavation or the risk of other operations in stratum.
