Buffering and energy dissipation device for slope protection

Abstract

The invention discloses a buffering and energy dissipation device for slope protection and belongs to the field of slope protection. The device is mainly composed of a chuck, a casing pipe used for accommodating the chuck, and a clamp, wherein the two ends of a through hole in the casing pipe is in different sizes, the larger end serves as a casing pipe head, the smaller end serves as a casing pipe body, and in this way, the chuck can only be placed in through the casing pipe head; the chuck is a conical cylinder, and the size of an internal channel of the chuck is identical with that of a rope; the clamp is composed of an upper clamp body and a lower clamp body, the structure and size of the upper clamp body are totally identical with those of the lower clamp body, the upper clamp body is mainly composed of a strip-shaped plate and a clamping part, a fixing hole is formed in one end of the strip-shaped plate, the other end of the strip-shaped plate is fixedly connected with the clamping part which can be arranged on the casing pipe head in a sleeving mode, a groove is formed in the clamping part, and the size of the groove is matched with the external profile of the casing pipe head. By the adoption of the device, damage caused by high local stress of a slope protection system and overloading of other components in the system can be avoided.

Description

technical field [0001] The invention relates to the technical field of slope protection, in particular to a slope protection buffer energy dissipation device which prevents ropes from yielding and being damaged and provides a certain buffer time for the system. Background technique [0002] Slope surface geological disaster protection has been widely used in slope management and protection in roads, railways, hydropower stations, mines, municipalities and scenic spots all over the country, and has solved some slope protection problems that were difficult to solve with traditional domestic technologies in the past. It has become a new method of slope prevention and control that keeps pace with the traditional technology represented by spray anchor and mortar masonry, and has achieved good results. At the same time, in the practice of flexible protection technology, especially when encountering cracks, landslides, debris flows and destructive geological disasters, the protecti...

Problems solved by technology

[0003] The mechanical properties of the buffer energy dissipation device must first meet its energy absorption capacity. Once it is insufficient, the protection capacity of the system cannot reach its rated energy level.

If the external force required for the function of the buffer energy dissipation device is too large, other components of the system may have undergone excessive deformation before it starts up, which will significantly increase the local force in the system, and even cause local damage.

On the other hand, if the external force required to exert the energy absorption capacity of the buffer energy dissipation device is too large, other components of the system may have been damaged due to overload before starting.

Neither of these two situations can make the function of the buffer energy dissipation device play a role normally, resulting in a reduction in the protection capability of the system.

In addition, if the buffer energy dissipation device breaks or slips during the process of absorbing deformation energy, it will inevitably fail to function further or the required external force will be greatly increased, which will not allow the design function of the buffer energy dissipation device to be fully utilized
