Description

Debris flow protection retaining wall

Technical Field

The invention relates to the technical field of debris flow safety protection, in particular to a debris flow protection retaining wall.

Background

The dynamic pressure of the slurry of the debris flow and the impact force of the rock block are typical impact loads and are characterized by short action times (in milliseconds, microseconds or even nanoseconds) but generate extreme pressures that ultimately cause media movement, material failure and overall structural failure. Under the condition of a complex geological environment, the traditional gravity retaining wall bears a special variable load effect, once dam collapse damage occurs in the debris flow outbreak process, not only can the expected prevention and control effect not be achieved, but also the dam body and the blocked solid matters can be a loose solid matter source of the debris flow and directly participate in the movement of the debris flow, the flow and the destructiveness of the debris flow are increased, and even more unexpected disaster loss can be caused.

Disclosure of Invention

The invention aims to provide a debris flow protection retaining wall which can play a good protection role in debris flow.

In order to solve the technical problems, the invention adopts the following technical scheme:

mud-rock flow protects barricade, including first base, second base, first dog, first base and second base pass through the connecting piece and connect, and first base top is provided with first dog, and first dog includes integrated into one piece's foam backplate, first spring layer, alloy steel board and second spring layer.

Further, the density of the first spring layer is greater than the density of the second spring layer.

Furthermore, evenly set up the screw hole of break-over connecting piece on the connecting piece, when using, fix subaerial through the screw.

Furthermore, a first connecting plate is arranged between the first stop block and the second base.

Further, a second connecting plate is arranged between the first stop block and the connecting piece.

Further, the thicknesses of the first spring layer and the second spring layer are consistent, and the thicknesses of the first spring layer and the second spring layer are larger than the thicknesses of the foam guard plate and the alloy steel plate.

Compared with the prior art, the invention has at least one of the following beneficial effects:

1. according to the invention, the first base and the second base are arranged, and the first baffle is arranged into the integrally formed foam guard plate, the first spring layer, the alloy steel plate and the second spring layer, so that when the protective cover is used, a better protective effect on debris flow can be achieved, and the protective cover has stronger deformation resistance.

2. Be provided with the screw hole on the connecting piece, can fix the barricade subaerial, increase its stability.

3. Be provided with first connecting plate and second connecting plate, can increase the stability of first dog.

Drawings

FIG. 1 is a schematic view of the structure of the present invention.

In the figure, 1-a first base, 2-a second base, 3-a first stop block, 4-a connecting piece, 5-a foam guard plate, 6-a first spring layer, 7-an alloy steel plate, 8-a second spring layer, 9-a threaded hole, 10-a first connecting plate and 11-a second connecting plate.

Detailed Description

As shown in fig. 1, in order to make the objects, technical solutions and advantages of the present invention more clearly understood, the present invention will be further described in detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.

Example 1

Mud-rock flow protects barricade, including first base 1, second base 2, first dog 3, first base 1 and second base 2 pass through connecting piece 4 and connect, and 1 top of first base is provided with first dog 3, and first dog 3 includes integrated into one piece's foam backplate 5, first spring layer 6, alloy steel plate 7 and second spring layer 8, when using, can play better guard action to the mud-rock flow to stronger anti deformability has.

Example 2

On the basis of embodiment 1, the density of the first spring layer 6 is greater than that of the second spring layer 7, so that the deformation resistance of the retaining wall can be improved.

Example 3

On the basis of embodiment 1, evenly set up the screw hole 9 of break-through connection spare on the connecting piece 4, when using, fix subaerial through the screw, increase stability.

Example 4

In addition to embodiment 1, the first connection plate 10 is provided between the first stopper 3 and the second base 2, and the stability of the first stopper can be increased.

Example 5

In addition to embodiment 1, the second connecting plate 11 is provided between the first stopper 3 and the connecting member 4, so that the stability of the first stopper can be increased.

Example 6

On the basis of embodiment 1, first spring layer 6 and second spring layer 8 thickness are unanimous to first spring layer 6 and second spring layer 8 thickness are greater than the thickness of foam backplate 5 and alloy steel plate 7, can play the purpose of protection mud-rock flow, increase anti deformability simultaneously.

Although the invention has been described herein with reference to a number of illustrative embodiments thereof, it should be understood that numerous other modifications and embodiments can be devised by those skilled in the art that will fall within the spirit and scope of the principles of this disclosure. More specifically, various variations and modifications are possible in the component parts and/or arrangements of the subject combination arrangement within the scope of the disclosure, the drawings and the appended claims.
