Description
Technical Field
The utility model belongs to the technical field of reform and expand engineering cutting high slope construction at highway, specifically a highway reforms and expands engineering high slope construction safety protection structure.
Background
The highway reconstruction and expansion project is influenced by the guarantee and the construction period, and the slope excavation amount can be reduced, the construction period can be shortened, and the influence of construction on traffic operation can be reduced to the maximum extent on the premise of ensuring the slope safety. Especially, the construction of the original high slope close to the passing highway and needing to dismantle masonry such as mortar and masonry or the construction of a stone slope is different from the construction of a common high slope, so that the construction is high in danger and can cause safety accidents by paying little attention.
Disclosure of Invention
The utility model discloses a guarantee highway's normal current, when taking precautions against because masonry side such as original high slope grout is demolishd or the stone slope excavation, the emergence of incident provides a highway and reforms transform and expand engineering high slope construction safety protection structure.
The utility model adopts the following technical proposal: the utility model provides a highway is reformed transform and is expanded engineering high slope construction safety protection structure, is including setting up the steel pipe framed bent in original side slope toe department, and the L type has been pour in the outside of steel pipe framed bent bottom and has supported the barricade, is provided with a plurality of drilling on the original side slope, and the drilling has inserted reinforcing bar stock and slip casting, and reinforcing bar stock outer end is connected with the steel pipe framed bent, and the top surface of original side slope is beaten and is established the earth anchor, and steel pipe framed bent top is passed through wire rope and is connected with the earth anchor.
Furthermore, the steel pipe bent is a trapezoidal structure with the bottom width larger than the top width, and the building height of the steel pipe bent is not lower than the height of the primary side slope of the original high side slope by more than 2 m.
Furthermore, the drilling direction is inclined downwards, the angle is not less than 20 degrees, the aperture is 50cm, the hole depth is not less than 2.5m, the distance between the drilling holes along the length direction of the steel pipe bent is 4m, the height direction is 3m, and the drilling holes are arranged in a quincunx shape.
Furthermore, one side of the original slope of the steel pipe bent is bound with a bamboo springboard and a steel wire mesh.
Furthermore, a new Jersey guardrail is arranged on the outer side of the L-shaped supporting retaining wall.
Compared with the prior art, the utility model provides a safety protection structure when being applicable to the high slope construction of steel pipe + bamboo springboard + wire net + safety net under the current condition of highway. Because the safety protection structure that existing highway adopted at the cutting section is the wave form guardrail, in order to increase the construction face, at first according to the construction needs, adopt new jersey guardrail to be fixed in the mode of original road surface structural layer, seal emergent lane to increase the crashproof ability of guardrail. The utility model discloses can prevent that the slope from opening the stone of digging earth, roll and fall highway.

Detailed Description
In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below, and it is obvious that the described embodiments are some, but not all, embodiments of the present invention; based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.
As shown in figures 1 and 2, a highway is reformed transform and is expanded engineering high side slope construction safety protection structure, including setting up steel pipe framed bent 4 in 3 toe departments of original side slope, the L type support barricade 2 has been pour to the outside of steel pipe framed bent 4 bottoms, is provided with a plurality of drilling on the original side slope 3, and reinforcing bar stock 6 and slip casting have been inserted in the drilling, and reinforcing bar stock 6 outer end is connected with steel pipe framed bent 4, and the ground anchor is established to the top surface of original side slope 3, and steel pipe framed bent top is passed through wire rope 5 and is connected with the ground anchor.
In order to guarantee highway's normal current, take precautions against because masonry square such as original high slope grout is demolishd or when stone side slope excavation, incident's emergence, the utility model provides a be applicable to under highway current condition, safety protection structure when the high slope construction of steel pipe + bamboo springboard + wire net + safety net.
Because the safety protection structure that existing highway adopted at the cutting section is the wave form guardrail, in order to increase the construction face, at first according to the construction needs, adopt new jersey guardrail 1 to be fixed in the mode of original road surface structural layer, seal emergent lane to increase the crashproof ability of guardrail.
And (3) lofting and excavating the soil shoulder under the condition of ensuring the width of the steel pipe bent 4. And (3) clinging to the outer side of the steel pipe bent, and pouring concrete into the L-shaped supporting retaining wall 2 to prevent the side slope from digging earth and rocks and rolling to fall on the highway.
Then, steel pipe bent frames 4 are erected between the slope feet of the original side slopes 3 and the newly poured L-shaped supporting retaining walls 2 by steel pipes with the diameter of 48 phi, for the stability of the steel pipe bent frames, the steel pipe bent frames are preferably erected in a trapezoidal mode with the bottom width slightly larger than the top width, and the erected height should be not lower than the height of the primary side slopes of the original high side slopes by more than 2 m.
The original side slope 3 is drilled by using a pneumatic drill, in order to enable the anchor rod to be stressed better, the drilling direction is inclined downwards, the angle is not less than 20 degrees, the aperture is 50cm, and the hole depth is not less than 2.5 m. The distance is 4m along the length direction of the steel pipe bent frame, the height direction is 3m, and the steel pipe bent frame is arranged in a quincunx shape. After the hole is punched, a steel bar anchor rod 6 with the diameter of phi 25 is inserted and grouted, so that the anchor rod is fixedly connected with the slope surface. One end of a phi 48 steel pipe is welded with the steel bar anchor rod, and the other end of the phi 48 steel pipe is connected with the steel pipe bent frame 4.
And (3) arranging a ground anchor on the top surface of the original first-level slope platform, and drawing the bent frame by using a phi 8 steel wire rope 5 at the top end of the steel pipe bent frame. Prevent that the steel pipe bent from falling to highway lane.
And binding bamboo springboards and steel wire meshes on the side surfaces of the steel pipe bent frames close to one side of the original slope.
Finally, it should be noted that: the above embodiments are only used to illustrate the technical solution of the present invention, and not to limit the same; although the present invention has been described in detail with reference to the foregoing embodiments, it should be understood by those skilled in the art that: the technical solutions described in the foregoing embodiments may still be modified, or some or all of the technical features may be equivalently replaced; such modifications and substitutions do not depart from the spirit and scope of the present invention.
