Abstract
The utility model discloses a kind of devices of branch steel arch-shelf shear stability at the beginning of raising, including conduit and guide cylinder, conduit includes the head being sequentially connected, catheter body and tail portion, several injected holes is evenly equipped in catheter body, one end of guide cylinder is connected with tail portion, the other end connect steel arch-shelf.Guide cylinder in the utility model increases the contact area of conduit and country rock, improves the shear stability of steel arch-shelf.
Description
Technical field
The utility model belongs to bridges in highway engineering technical field more particularly to a kind of raising, and just branch steel arch-shelf shearing resistance is stablized
The device of property.
Background technology
When the underground engineerings such as tunnel, subway pass through broken, weak surrounding rock, the steel that is usually made of H profile steel segmented welding
Arch determines the H-type of the spacing and composition steel arch-shelf of arch as country rock preliminary bracing, and according to rock crusher, deformation
The size of steel.The vcehicular tunnel of two-way four-lane or six-lane, cross section is big, free height, and the length of steel arch-shelf is long, cross section
It is small；During country rock convergent deformation, steel arch-shelf is easy unstability, generally occur within steel arch-shelf distort, misplace, being broken, invading boundary etc. it is tight
Ghost image rings the problem of safety for tunnel engineering and construction quality.It is thicker that two diameters are set at a certain distance usually on steel arch-shelf
Reinforcing bar, there was only frictional resistance as its fixation, but between bar reinforcement and country rock and without any cohesive force, for weak, broken
For broken country rock, the frictional resistance between bar reinforcement and country rock is not enough to solve the deformation of steel arch-shelf.
It can be seen that the prior art is up for further improving.
Utility model content
The utility model is that it is anti-to provide a kind of first branch steel arch-shelf of raising in place of avoiding above-mentioned the shortcomings of the prior art
Cut the device of stability.
Technical solution used by the utility model is：
A kind of device of the first branch steel arch-shelf shear stability of raising, including conduit and guide cylinder, conduit include being sequentially connected
Head, catheter body and tail portion, several injected holes are evenly equipped in catheter body, one end of guide cylinder is connected with tail portion, is another
One end connects steel arch-shelf.
Several described injected holes are arranged in catheter body in blossom type, and the equal penetrating catheter ontology of each injected hole
Tube wall.
The head is in sharp shoe-like.
It is detachable connection between the tail portion and guide cylinder.
To be threadedly coupled between the tail portion and guide cylinder, tail portion is provided with external screw thread, is connected with tail portion on guide cylinder
One end is provided with internal thread compatible with the external screw thread.
By adopting the above-described technical solution, having the beneficial effect that acquired by the utility model：
Conduit and guide cylinder in the utility model can fix steel arch-shelf well, and after slip casting, slurry passes through each slip casting
Hole is penetrated into rock stratum surrounding, and enhance the steel arch-shelf being connected with conduit cuts ability, during use, when steel arch-shelf plays pendulum
When to cause shear action to conduit and guide cylinder, because the case portion of guide cylinder and the contact area of country rock are big, play to leading
The firm effect of pipe improves the shear stability of first branch steel arch-shelf.

Specific implementation mode
The utility model is described in further detail with specific embodiment below in conjunction with the accompanying drawings, but the utility model
It is not limited to these examples.
As shown in Figures 1 to 4, the device of the first branch steel arch-shelf shear stability of a kind of raising, including conduit and guide cylinder 5.
The conduit includes the head 1 being sequentially connected, catheter body 3 and tail portion 4.The head is in sharp shoe-like, convenient for peace
Head can smoothly enter into country rock when dress.Several injected holes 2 are evenly equipped in catheter body 3.Several described injected holes 2 are in conduit
It is arranged in blossom type on ontology 3, and the tube wall of 2 equal penetrating catheter ontology 3 of each injected hole.One end of the guide cylinder 5 with
Tail portion 4 is connected, the other end connects the H profile steel 7 for forming steel arch-shelf.
It is detachable connection between the tail portion 4 and guide cylinder 5.Preferably, it is between the tail portion 4 and guide cylinder 5
It is threadedly coupled, tail portion 4 is provided with external screw thread 6, and the one end being connected with tail portion 4 on guide cylinder 5 is provided with suitable with 6 phase of the external screw thread
The internal thread 54 matched.Specifically, the guide cylinder 5 includes connected positioning region 51 and case portion 52.The positioning region 51
It is cylindrical, and the size of positioning region is adapted with the size of tail portion 4.The inside in positioning region 51 is arranged in above-mentioned internal thread 54.
The case portion 52 is in funnel-form, and the interior one end being connected without leave with positioning region 51 in case portion 52 is to one to be connected with H profile steel 7
End gradually increases.The side in the case portion 52 is fixed with the positioning plate 53 for installing steel arch-shelf, and positioning plate 53 has two pieces, and two
Block positioning plate 53 cooperatively forms the card slot for installing H profile steel 7.
The use process of the device for improving first branch steel arch-shelf shear stability in the utility model generally include as
Lower step：
Step 1, the head of conduit is directed at country rock, taps the tail portion of conduit, until the part that conduit removes tail portion is whole
Into country rock；
Step 2, the slip casting into conduit from catheter tail, slurry are penetrated by injected hole to rock stratum surrounding；
Step 4, after slip casting terminates 2~3 hours, guide cylinder, which is installed to catheter tail, and turns guide cylinder makes guide cylinder
Case portion come into full contact with country rock, re-direct later cylinder side installation steel arch-shelf.
The part that do not addressed in the utility model uses or uses for reference prior art and can be realized.
Specific embodiment described herein is only the spiritual example explanation to the utility model.This practicality
