Description

Technical Field

[0001] The utility model relates to a prevention and control measure for dangerous rock disasters on steep and gentle slopes, in particular to a dangerous rock energy dissipation pile in a cone-shaped column. Background Art

[0002] In mountainous slope protection, in terrain conditions where the front half of the slope is steep and the back half is flat, dangerous rocks often slide down the steep slope at extremely high speeds due to the steepness of the slope. Their trajectory is also affected by multiple factors such as slope and rock type, generating strong impact forces and significantly increasing the danger. This impact force not only increases damage to transportation projects and buildings at the foot of the slope, but can also cause serious casualties and economic losses, posing a significant threat to surrounding infrastructure and residents' lives. Therefore, traditional protective measures are often limited in their effectiveness against such strong impacts of dangerous rocks. In such cases, more effective and innovative protection technologies are needed to improve defenses against dangerous rocks and reduce the risks and losses caused by disasters.

[0003] In the existing construction process, most energy dissipation piles have the same diameter at the top and bottom, and a conical bottom. Although this structure simplifies the construction process and reduces construction difficulty and cost, this protective energy dissipation measure often has limited protection against strong impacts of dangerous rocks, and its crushing efficiency and energy efficiency for dangerous rocks are not high.

[0007] Preferably, the outer protective plate is provided with circular through holes and square through holes.

[0008] Preferably, the cross-section of the support column is a regular octagon, and includes a connecting piece and a fastener. The connecting piece is a regular octagonal ring structure, which is fixed around the column body of the support column in a segmented form; the fastener is embedded in a ring array on each side of the outside of the connecting piece. The fastener is a hollow cylinder with a thread arranged inside for fixed connection with the energy dissipation protrusion.

[0009] Preferably, the fastener and the connecting member are tilted at a certain angle so that the energy dissipation protrusion is perpendicular to the curved surface of the outer protective plate.

[0010] Preferably, the energy dissipation protrusion includes an energy dissipation prism, a connecting rod, a fixed block, a bolt, an end guard and a spring. The energy dissipation prism is the part that directly contacts the dangerous rock to dissipate energy. It is connected to the fixed block through a connecting rod. The fixed block is provided with a thread inside. The two ends of the spring are respectively inserted into the end guards, wherein the end guard at one end is connected to the fixed block by a first bolt, and the end guard at the other end is connected to the fastener by a second bolt.

[0014] Beneficial effects of the utility model:

[0015] 1. The utility model makes it difficult for dangerous rocks to roll out during collision and energy dissipation through the concave design of the pile body and the arrangement of the fixed cover and tray, thereby improving the efficiency of crushing dangerous rocks and energy consumption.

[0016] 2. The utility model uses a retractable spring in the connection of the energy dissipation protrusion component, so that the energy dissipation protrusion can absorb and disperse energy through the elastic deformation of the spring when the dangerous rock impacts. After the dangerous rock is broken, the spring rebounds and the energy dissipation protrusion returns to its original shape, continuing to break and dissipate energy for the next dangerous rock that rolls down, effectively protecting the energy dissipation pile structure.

[0017] 3. The setting of the internal threads of the fixing block and the fastener in the utility model increases the friction and stability of the connection, ensuring that the energy dissipation protrusion can be firmly fixed on the supporting column under the action of external forces such as dangerous rock impact, thereby effectively playing the role of energy dissipation; at the same time, the bolt connection method has the advantage of easy installation, convenient regular replacement and maintenance, and improves the service life of the energy dissipation building.

[0018] 4. The utility model sets the fasteners and the connecting parts at a certain angle so that the energy dissipation protrusions are perpendicular to the arc surface of the energy dissipation pile, thereby reducing the offset of the impact force of the dangerous rock rolling on the pile body, reducing the damage to the energy dissipation structure during the energy dissipation process, and improving the energy dissipation efficiency.

[0037] S1.

Place the base 10 in the pit and adjust its level and position to ensure it aligns with the installation position of the energy dissipation pile. Pour concrete into the pit to secure the base 10. The concrete strength and mix ratio should meet the design requirements.
