Examples

The existing steel shed tunnel buffer protection technology is considered from the aspect of improving the shock resistance of the structure, the mode can improve the vertical shock resistance of the steel shed tunnel, but has little protection effect on lateral loads, and the accident that the steel shed tunnel is broken to bury an automobile passing on a road below the steel shed tunnel occurs.

Therefore, in a concave slope with a steep upper part or a gentle slope section at the slope foot, the collapsed falling rocks can roll downwards along the slope to the inner side of the steel shed tunnel after falling, namely, the area between the steel shed tunnel and the slope, so that a large lateral impact load is generated on the steel shed tunnel, the lateral thrust resistance of the steel shed tunnel is poor, and the steel shed tunnel is easy to bend and damage due to lateral rolling rock impact or rock-soil body extrusion, so that the whole body collapses. Therefore, the method has serious defects in the protection of the collapse rockfall of the terrain with the slope toe being a gentle slope.

In order to solve the lateral protection problem of the steel shed tunnel on the concave slope section with the slope toe being slow, the inventor provides a structure protection structure through long-term research.

The structure protection structure in the embodiment of the application is used for reducing the side impact load of the collapsed and collapsed stone on the structure after rolling. The structure in this application may be a shed tunnel, retaining wall, or the like. The method can be used for the road emergency repair stage affected by the collapse rock fall disaster and can also be used for the road construction stage.

Referring to fig. 1, the structure protection structure 100 includes a side slope 110, a supporting stop 120, a first buffer 130, a lightweight concrete body 140, and a bolt assembly 150.

The slope 110 has a slope surface, i.e. the surface of the slope 110, and the slope surface is step-shaped. During construction, the slope 110 may be excavated by using an apparatus, or the slope 110 may be blasted to form a plurality of steps. The upper surface of the step is horizontal, and can support the lightweight concrete body 140 relative to the inclined slope, and the lightweight concrete body 140 is not easy to slide along the slope.

The supporting block 120 is vertically arranged and one end of the supporting block 120 is buried in the side slope 110. In particular embodiments, the support baffle 120 includes a truss and a steel plate 133, the truss being vertically disposed, the steel plate 133 enclosing an outer surface of the truss, the truss being included within the steel plate 133. The connection mode between the truss and the steel plate 133 may be welding, flange connection, or the like.

When the device is specifically arranged, one end of the first buffer body 130 is connected with the slope. The other end of the first buffer body 130 is connected with the other end of the supporting baffle 120, the first buffer body 130 is arranged obliquely, and one end of the first buffer body 130, which is far away from the side slope 110, is lower than one end of the first buffer body 130, which is close to the side slope 110, so that the collapsed falling rocks can roll on the upper surface of the first buffer body 130, and the collapsed falling rocks are prevented from being accumulated. For those skilled in the art, the inclination angle of the first buffer body 130 needs to be considered in combination with the actual engineering, and the purpose of the inclination angle is to change the motion trajectory of the falling rocks and avoid the collision with the side surface of the structure. The first cushion 130, the support baffles 120, and the slope 110 enclose a filling cavity.

The lightweight concrete body 140 is filled in the filling cavity. In other embodiments, it may be constructed of foam concrete. On one hand, the lightweight concrete body 140 can support the first buffer body 130 to prevent falling rocks from rolling down the slope surface to break the structure protection structure 100; on the other hand, the light concrete body 140 with the same volume has lighter weight compared with the common concrete body, and the extrusion effect on the supporting baffle 120 is smaller, so that the instability damage caused by the excessive extrusion is avoided.

In some specific embodiments, the first buffer body 130 includes a buffer layer 131 and a steel plate 133, wherein the buffer layer 131 is disposed on the upper surface of the lightweight concrete body 140, and the steel plate 133 is disposed on the surface of the buffer layer 131. The steel plate 133 has high hardness, and cannot cause excessive damage to the steel plate 133 when colliding with the steel plate 133 after falling of the falling rocks, and the damage form of the steel plate 133 is mainly scratches on the surface of the steel plate and cannot influence the normal operation of the steel plate 133. The buffer layer 131 can absorb kinetic energy of the collapsing rocks by deformation, and the influence on the structure is reduced.

In other embodiments, the cushioning layer 131 may be formed of a rubber material. Illustratively, the breaker 131 may be composed of a plurality of junked tires.

In this embodiment, the anchor assembly 150 includes a first anchor 151 and a second anchor 153, the first anchor 151 is disposed obliquely, one end of the first anchor 151 is fixed in the support stopper 120, and the other end is fixed in the slope 110. The first anchor 151 functions to improve the overall stability of the support baffle 120 and the slope 110, and one end of the first anchor 151 is fixed in the support baffle 120 and the other end is fixed in the slope 110. When the support baffle 120 is subjected to lateral compressive force, the first anchor 151 has a traction effect on the support baffle 120, which can improve the stability of the support baffle 120.

One end of the second anchor rod 153 is fixed in the first buffer body 130, and the other end is fixed in the lightweight concrete body 140. The second anchor rod 153 functions to improve the integrity of the lightweight concrete body 140 and the first buffer body 130. For the side slope with serious rock weathering, the rock structure is broken, and the side slope is easy to roll down along the slope surface under the erosion action of rainwater. The falling frequency of the collapsed falling stones is high, when the falling stones fall to the first buffering body 130, the kinetic energy of the falling stones is large, the impact force on the first concrete is large, the lightweight concrete body 140 is connected with the first buffering body 130 through the second anchor rod 153, the lightweight concrete body 140 and the first buffering body 130 are improved, and the first buffering layer 131 is not prone to displacement.

In some embodiments, the structure-protecting structure 100 further includes a tendon-embedded body 160, and one end of the tendon-embedded body 160 is fixed in the lightweight concrete body 140 and the other end is fixed in the slope 110. As mentioned above, the slope is stepped in shape to further improve the stability of the lightweight concrete body 140. The bar-embedded bodies 160 can be arranged, and the bar-embedded bodies 160 can improve the integrity of the lightweight concrete body 140 and the side slope 110 and can improve the sliding resistance of the lightweight concrete body 140.

For the convenience of understanding the tendon-planting body 160 in the present application, the tendon-planting process is briefly described below.

The steel bar planting means that a hole is drilled in a base material such as concrete, rock and the like, then high-strength steel bar planting glue is injected, then a steel bar or a section bar is inserted, and the steel bar and the base material are bonded into a whole after the glue is solidified, so that the steel bar planting method is a building engineering technology commonly used in the reinforcing industry.

For example, in the present application, concrete may be poured on the slope surface, then a hole is drilled in the concrete, the drilled hole penetrates through the concrete and extends into the side slope 110, then a high-strength steel bar-planting adhesive is injected, then a steel bar is inserted, the steel bar is bonded to the concrete after the adhesive is cured, and the steel bar is bonded to the rock mass of the side slope 110 to form the steel bar-planting body 160.

Referring to fig. 2, in some embodiments, the structure protection structure 100 further includes a skid-resistant base 170, the skid-resistant base 170 is disposed at a toe of the side slope 110, one end of the skid-resistant base 170 is embedded in the side slope 110, and the other end is disposed in the filling cavity. The anti-skid base 170 is used for stabilizing the slope toe, and further improving the anti-skid capability of the lightweight concrete body 140.

illustratively, one side of the slide-resistant base 170 close to the slope surface abuts against the slope 110, i.e. one side of the slide-resistant base 170 close to the slope surface abuts against the slope surface of the slope 110. The shear outlet of the side slope 110 is generally located at the toe of the side slope 110 if the slope 110 fails to collapse due to a destabilizing failure. If the slide-resistant base 170 is attached to the side slope 110 so that there is an interaction between the slide-resistant base 170 and the side slope 110, the slide-resistant base 170 can also prevent the side slope 110 from sliding when the side slope 110 slides unstably.

The failure mode of the slope 110 is mainly two failure modes of a slip type and an overturn type. The lightweight concrete body 140 is also essentially a potential slip body. In order to prevent the lightweight concrete body 140 from sliding damage, the anti-sliding force of the lightweight concrete body 140 is improved by the embedded rib body 160.

In some embodiments, in order to improve the anti-overturning force of the lightweight concrete, the structure protection structure 100 further includes a steel pipe pile 180, the steel pipe pile 180 penetrates through the skid-resistant base 170, and one end of the steel pipe pile 180 is located in the lightweight concrete body 140 and the other end is located in the side slope 110. Illustratively, the steel pipe pile 180 is vertically disposed.

The falling rocks which have fallen roll forward and continue to roll, transition from the first buffer body 130 to the second buffer body 500, and finally roll out along the second buffer body 500, so that the falling rocks which have fallen are prevented from colliding with the side surface of the shed tunnel support 300, and the shed tunnel support 300 is protected.
