Specific embodiment
In order to make the objectives, technical solutions, and advantages of the present invention clearer, with reference to the accompanying drawings and embodiments, right
The present invention is further elaborated.It should be appreciated that the specific embodiments described herein are merely illustrative of the present invention, and
It is not used in the restriction present invention.
Embodiment 1
The present embodiment provides a kind of anchors to draw the light-duty tunnel portal of armored concrete and its construction method, packet referring to FIG. 1-2,
Include tunnel mechanism 1, portal mechanism 2.
Tunnel mechanism 1 includes facing upward slope 11, tunnel 12, and the one end in tunnel 12 has an opening, and opening, which is located at, faces upward slope 11
Bottom, tunnel 12 are located at the inside for facing upward slope 11, and the one end in tunnel 12 has an opening for vehicles disengaging.
Portal mechanism 2 includes portal wall 21, main reinforcement 22, multiple anchor poles 23, and portal wall 21 is fixed on opening, portal wall 21
Inside there is the through-hole in a connection tunnel 12, main reinforcement 22 is located in the side wall of portal wall 21 and circular through-hole, main reinforcement 22 are adopted
With reinforced mesh structure, so that the contact area between main reinforcement 22 and the concrete of portal wall 21 is bigger, portal wall 21 and main reinforcement
Connection between 22 is more firm, and one end of multiple anchor poles 23 is fixedly connected with main reinforcement 22, and the other end of multiple anchor poles 23, which protrudes into, to be faced upward
In slope, portal mechanism 2 is used to fix the opening in tunnel 12, prevents partial collapse, and main reinforcement 22 is irregular annular enclosed type
Structure, and the edge of the opening around tunnel 12, portal wall 21 is formed using concreting and size is greater than opening for tunnel 12
Mouthful size, the through-hole anchor pole 23 with a connection opening in the middle part of portal wall 21 is spaced downwards along the short transverse for facing upward slope to be set
It sets, and multiple anchor poles 23 are symmetrical set in the two sides of the Axisymmetric Distributed Line of the vertical direction of opening, multiple anchor poles 23 are between any two
It is parallel to each other, mixed mud has been poured between anchor pole 23, and be connected and fixed between anchor pole 23 by concrete, thus anchor pole 23 and anchor
Concrete between bar 23 constitutes the reinforced concrete wall of a connection portal wall 21, can further reinforce to portal wall 21.
Anchor pole 23 includes threaded rod 231, multiple groups locating rod group, and threaded rod 231 is able to maintain that the structural stability of anchor pole 23,
And in 231 outside casting concrete of threaded rod, the company between concrete and threaded rod is firm, and contact area is big, every group of positioning
Bar group includes the locating rod 232 of three bending structures, and the both ends of locating rod 232 are weldingly fixed on threaded rod 231, locating rod
232 use round reinforcing bar, and the angle formed between three locating rods 232 in same group of locating rod group is 120 degree, locating rod
232 pairs of threaded rods 231 are supported, so that the structure in slope 11 is more firm facing upward for threaded rod 231, one end of threaded rod 231 is logical
Billet connection main reinforcement 22 is crossed, the side of main reinforcement 22 is close in the side of billet, and threaded rod 231 is perpendicular to billet, billet
Two sides be fixedly connected by welding respectively threaded rod 231 and main reinforcement 22.
Portal wall 21 is fixed with a rhone 24 at the top of the side wall for facing upward slope 11, and rhone 24 will be for that will face upward slope
The ponding flowed down on 11 is discharged from the two sides of portal wall 21, avoids ponding from being flushed on the road surface of the opening in tunnel 12, traffic work
The opening traveling having in tunnel 12 is safer.
In conclusion a kind of anchor of the invention draws the light-duty tunnel portal of armored concrete, slope 11 is faced upward by multiple be fixed on
Interior anchor pole 23 reinforces portal wall 21, to casting concrete between a anchor pole 23 so that anchor pole 23 and anchor pole 23 it
Between concrete constitute connection portal wall 21 reinforced concrete wall, so that the structure of portal wall 21 is more firm, in addition, anchor pole 23
Self structure intensity is big, light weight, while the whole structural strength for increasing tunnel portal of the invention, and has excessive increasing
Add tunnel portal quality, reduce the risk of partial collapse, use is safer, and easy for construction.
Embodiment 2
Please refer to Fig. 1 and Fig. 2, a kind of construction party of the anchor drawing light-duty tunnel portal of armored concrete provided in this embodiment
Method, it is suitable for the anchors in embodiment 1 to draw the light-duty tunnel portal of armored concrete, and steps are as follows:
Step 1: successively being excavated for burying downwards in the slope surface for facing upward slope 11 of the one end in tunnel 12 along short transverse
The bolthole of anchor pole 23, bolthole are divided into multilayer according to the position in short transverse of anchor pole 23, excavate one layer of bolthole every time.
Step 2: anchor pole 23 being protruded into bolthole, the casting concrete between anchor pole 23, the concrete note in bolthole
Slurry uses slip casing by pressure, and grouting pressure is not less than 0.6Mpa.
Step 3: being repeated in and carry out step 1 and step 2 to install whole anchor poles 23, main reinforcement 22 is placed in tunnel 12
One end, and weld billet between main reinforcement 22 and anchor pole 23 to be fixedly connected with one end of main reinforcement 22 and anchor pole 23.
Step 4: in the outside of main reinforcement 22, perfusion wraps up the concrete of main reinforcement 22 to constitute portal wall 21.
In conclusion a kind of anchor of the present embodiment draws the construction method of the light-duty tunnel portal of armored concrete, excavate first
Bolthole is to bury anchor pole 23, and then the casting concrete between anchor pole 23, the concrete between anchor pole 23 and anchor pole 23 are constituted
Main reinforcement 22 is then placed in the one end in tunnel 23, and is fixedly welded the one of anchor pole 23 using billet by reinforced concrete wall
End and main reinforcement 22 finally pour concrete of the concrete for being wrapped in 22 outside of main reinforcement to constitute portal wall 21, in portal wall 21
Concrete between anchor pole 23 is connected, and the present embodiment maintains the stability of slopes after portal wall 21, and anchor pole by anchor pole 23
Then prevent part from collapsing by relatively thin armored concrete between 23, stabilized structure, construction is simple.
The foregoing is merely illustrative of the preferred embodiments of the present invention, is not intended to limit the invention, all in essence of the invention
Made any modifications, equivalent replacements, and improvements etc., should all be included in the protection scope of the present invention within mind and principle.
