Description

Technical Field

[0001] The utility model relates to the technical field of hydraulic structures, in particular to a corridor structure for preventing rockfall. Background Art

[0002] During the implementation of hydropower projects, the particularity of the geographical location and the complexity of the topographic and geological conditions have brought many challenges to road construction. These roads often need to cross canyon areas, and their steep slopes are affected by factors such as the development of bedrock joints, the cutting of unfavorable structural surfaces, and the collapse of slopes due to unloading, resulting in poor rock stability. This situation is very likely to cause a large number of rolling stones and falling rocks, thus posing a serious threat to road safety within the management scope of the hydropower project and a serious threat to the lives of managers.

[0003] Publication No. CN217419675U discloses a heavy-duty corridor structure for protecting a rocky high and steep slope road, including a corridor body arranged along the rocky slope, a corridor is arranged in the corridor body along the direction in which it is arranged, a structural deformation expansion joint is arranged every 10m along the direction in which it is arranged, a corridor internal road surface is arranged at the bottom of the corridor, an anchoring structure connected to the slope is arranged on the inner side of the corridor body close to the slope, several ventilation and lighting openings are arranged at intervals on the outer side of the corridor body away from the slope, and a top backfill body connected to the slope is arranged on the top of the corridor body; after careful evaluation, the heavy-duty corridor structure mentioned in the public document has certain advantages in ensuring road safety, however, in the actual construction process, the structure will significantly increase the construction cost and prolong the construction period. Compared with this technical solution, its economic efficiency is relatively poor. Utility Model Content

[0018] Embodiment. A corridor structure for preventing rockfall, the structure of which is referenced Figure 1 , including an arch 1, the top of the arch 1 is provided with an anti-collision buffer structure, the anti-collision buffer structure includes enclosures 2 arranged on both sides of the arch, and the enclosures 2 are provided with sand cushion layers and drainage layers from top to bottom; one side of the bottom of the arch 1 is a concrete wall structure, and a number of support columns 3 are arranged on the other side and the center line, and a base 4 is arranged at the bottom of each support column 3. The sand cushion layer is arranged to form a sandstone skeleton structure to improve the strength while having a certain elastic deformation capacity, which can fully alleviate the impact effect caused by falling rocks.

[0019] The drainage layer includes drainage blind materials, which are arranged at intervals in the horizontal direction of the length of the arch 1, and drainage outlets are connected to both ends of the drainage blind materials, which are arranged at the bottom of the enclosure 2. The use of drainage blind materials can not only complete the drainage work, but also ensure that the drainage layer has a corresponding structural strength and is not easily damaged by falling rocks during actual use.

[0020] The arch 1 is arranged with undulations along the length direction, and the drainage blind material is arranged in the depressions arranged with undulations on the arch 1. The arch 1 is arranged with regular convex and concave shapes along the length direction, and the drainage blind material is arranged in the depressions perpendicular to the length direction of the arch 1, and the water flow is collected in the depressions by utilizing the slope generated by the undulations, and then discharged through the drainage blind material and the drainage outlet.

[0021] The drainage blinds are arranged along both sides of the length direction of the arch 1, and form a complete passage with the drainage blinds arranged transversely. By arranging the drainage blinds on both sides of the length direction of the arch 1, the characteristics of the arch 1 itself, which is high in the middle and low at both ends, are utilized to facilitate the water flow to gather on both sides of the arch 1, and then be guided to the drainage outlet through the drainage blinds.

[0022] The material of the arch 1, enclosure 2, support column 3 and base 4 is reinforced concrete. By uniformly using reinforced concrete material, the rigidity and strength of the whole structure can be improved by integral casting during the construction process. The corridor structure of the rockfall prevention can also be pre-supported by the reinforced concrete structure pre-support technology, and then transported to the required location for installation and construction, thereby reducing the construction period.

[0023] The working principle and use method of the utility model are as follows: the anti-rockfall corridor structure is constructed at the rockfall site of the water conservancy project and implemented according to the above structure, wherein the concrete wall structure on one side of the bottom of the arch 1 is close to the mountain, and the bonding performance of the concrete is utilized to fully combine with the mountain; the strength of the reinforced concrete structure, the structural characteristics of the sand cushion layer and the drainage blind material are fully utilized to ensure that the utility model is not damaged by falling rocks during use, thereby ensuring the safety of personnel.

[0024] Obviously, the above is only a part of the embodiments of the utility model, not all of the embodiments. The above embodiments are not used to limit the utility model. For those skilled in the art, the utility model can have various changes and variations. Any combination, modification, equivalent replacement, improvement and all other embodiments that can be made by ordinary technicians in the field within the spirit and principle of the utility model should be within the protection scope of the utility model.
