Description
Technical field
The utility model belongs to tunnel support steel arch-shelf technical field more particularly to a kind of whole branch of full section of tunnel construction
Protect steel arch-shelf terminal pad.
Background technique
For country's Tunnel Engineering frequently with composite lining structure, tunnel steel arch frame is the composition portion of Tunnel at present
Point, main function is resistant to the initial stage convergent deformation that country rock is generated due to excavation disturbance.Steel arch-shelf is fragmented under normal conditions
It is transported to construction site, the face after excavating manually is attached it to by worker.During installation, first that steel arch support is good,
Tunnel inner wall squeezes into anchor pole, and anchor pole and steel arch-shelf are welded together, and the above method has the following deficiencies: first, due to will
Anchor pole welds together with steel arch-shelf, and the tunnel of cutting is limited to by electric power etc., and welding difficulty is big, and since face is easy
Existing falling rocks etc., increases accident rate；Second, welding quality is low due to being limited by welding position, it is easy to snap, causes
Steel arch-shelf bending；Third, the best Impact direction due to anchor pole present position is different, anchor pole is inserted into the direct shadow of angle of tunnel wall
Ring anchor rod strength；For existing method it is difficult to ensure that anchor pole is on best Impact direction, anchoring strength is low.
Utility model content
It is complete that the technical problems to be solved in the utility model is just to provide a kind of tunnel that a kind of anchoring strength is big, easy for construction
Section construction integer support steel arch-shelf terminal pad.
To solve the above problems, the technical solution adopted in the utility model are as follows: including first flange disk and second flange disk,
It has been provided with anchor pole locating rack on the first flange disk or second flange disk, has been provided with anchor pole on the anchor pole locating rack
Guide sleeve is provided with connection bolt in the connecting hole on the first flange disk and second flange disk.
Its additional technical feature are as follows:
The first flange disk and second flange disk side are flexibly connected by bindiny mechanism；
The bindiny mechanism is the hinge shaft connecting with the first flange disk and second flange disk.
A kind of full section of tunnel construction integer support steel arch-shelf terminal pad and the prior art provided by the utility model
It compares, has the advantage that first, due to including first flange disk and second flange disk, in the first flange disk or second
It has been provided with anchor pole locating rack on ring flange, has been provided with anchor pole guide sleeve on the anchor pole locating rack, in first method
Be provided with connection bolt in connecting hole on blue disk and second flange disk, first flange disk and second flange disk respectively with need to connect
The two segmentation steel arch-shelfs up and down connect are fixed together, and the connecting hole of first flange disk and second flange disk is aligned, and are led to
It crosses connection bolt first flange disk and second flange disk link together, squeezes into anchor pole, anchor pole along anchor pole guide sleeve direction
It is directly connected and fixed with anchor pole guide sleeve, and anchor pole direction of insertion is consistent with anchor pole guide sleeve direction, does not need
It separately welds, construction is simple, bonding strength is big, and anchor pole is not easy to deviate from, and anchor pole direction of insertion is the best anchoring of design
Direction；Different for the anchor pole guide sleeve direction in the terminal pad of different location, anchor pole guide sleeve is according to locating for terminal pad
Position set different directions；Second, since the first flange disk and second flange disk side are connected by bindiny mechanism's activity
Connect, in steel arch-shelf production process, by need with the terminal pad connect steel arch-shelf both ends respectively with first flange disk and second
Ring flange welds together, and first flange disk and second flange disk are flexibly connected by bindiny mechanism, when completing the process, will lead to
The steel arch-shelf for crossing terminal pad connection folds, and is fixed by holding clamp or rope, will when transporting supporting position
Holding clamp or rope are opened, and with the mechanical picking-up in the middle part of upper arch is lifted, middle arch rack and lower arch are under self gravitation effect
It is sagging, at this point, under the limit of bindiny mechanism, the connecting hole automatic aligning of first flange disk and second flange disk, so that connection
Bolt can be readily intercalated into, and will connect the nut tightening on bolt, shorten staff in the operating time of supporting position,
Reduce because of falling rocks or the incidence to cause the accident of collapsing, and improve installation effectiveness, reduces labor intensity；Third, by
In the bindiny mechanism be the hinge shaft being connect with the first flange disk and second flange disk, first flange disk and second flange disk
Hinge shape is formed with hinge shaft, the connecting hole on such first flange disk and second flange disk is not easy to deviate, and installation speed is fast.
Detailed description of the invention
Fig. 1 is a kind of structural schematic diagram of full section of tunnel construction integer support steel arch-shelf terminal pad of the utility model；
Fig. 2 is a kind of installation diagram of full section of tunnel construction integer support steel arch-shelf terminal pad；
Fig. 3 is a kind of full section of tunnel construction integer support steel arch-shelf that first flange disk is connected with second flange disk activity
With terminal pad structural schematic diagram.
Specific embodiment
With reference to the accompanying drawings and detailed description to a kind of full section of tunnel of the utility model construction integer support steel arch
It the structure of frame terminal pad and is described in further details using principle.
As depicted in figs. 1 and 2, a kind of knot of full section of tunnel construction integer support steel arch-shelf terminal pad of the utility model
Structure schematic diagram, a kind of full section of tunnel construction integer support steel arch-shelf terminal pad of the utility model includes 1 He of first flange disk
Second flange disk 2 has been provided with anchor pole locating rack 3 on first flange disk 1, and anchor pole guiding is provided on anchor pole locating rack 3
