Description

Technical Field

[0001] The utility model relates to the technical field of slope protection, in particular to a roadbed slope protection device. Background Art

[0002] Roadbed refers to the strip structure built as the foundation of the road surface according to the installation route location and certain technical requirements. There are often some protrusions or stones falling onto the road surface on the side slopes of the roadbed, affecting the normal driving of cars, so the side slopes of the roadbed need to be protected.

[0003] When the existing slope protection device is fixedly installed on the roadbed slope, a heavy hammer is used to hammer the nail body into the inside of the slope, so that the slope protection device is installed and fixed. However, if the protective net is too much gravel, the gravity of the gravel causes the nail body to be pulled out from the inside of the slope, and the nail body cannot withstand the excessive gravity, resulting in the slope protection device being not firmly fixed to the slope and easily falling off. In order to solve the problems existing in the prior art, the utility model with publication number CN220365020U discloses a slope protection device (hereinafter referred to as: prior art 1), comprising two bases, characterized in that the inner ends of the two bases are rotated by a rotating mechanism The base is dynamically connected with a protective net, and a fixing pile for inserting into the slope soil layer is provided at the bottom end of the protective net, and a mounting mechanism is installed at the bottom end of the two bases, and the mounting mechanism is used to fix the two bases at the high point and the low point of the slope respectively; the mounting mechanism includes a first plug rod, a nail body, a driving assembly, and a locking assembly; the first plug rod is a hollow structure, the first plug rod is fixedly connected to the bottom end of the base, and the first plug rod is used to insert into the slope soil layer; the driving assembly is used to drive the nail body to move radially to the outside of the first plug rod and insert into the inside of the slope; the locking assembly is used to limit and fix the moving position of the nail body.

[0004] Although the prior art 1 improves the reliability of the protective net installed on the slope by setting up an installation mechanism to drive the nail body to be inserted deeper into the slope, but only a single layer of protective net is set in the prior art 1. When the impact force generated by the rolling of gravel is large, the protective net used to block the gravel is easily damaged. Utility Model Content

The first sliding part 112 and the second sliding part 113 fixedly connected to the left and right sides of the first protective net move toward the center line of the first protective net body 111 as the first protective net is deformed. The first sliding part 112 and the second sliding part 113 are connected to the second protective net assembly 106 through the connecting mechanism 107. Driven by the connecting mechanism 107, the second protective net assembly 106 will bend in the direction opposite to the curvature of the first protective net assembly 105, thereby decomposing the impact force of the gravel.
