Embodiment 1

[0037] see now Figure 1-Figure 3 , figure 1 It is the elevation view of the protective net used for slope rockfall prevention according to the embodiment of the present invention, figure 2 It is a sectional view of the protection net used for slope rockfall prevention according to the embodiment of the present invention, image 3 It is a structural schematic diagram of a steel cable anchor rod according to an embodiment of the present invention. As shown in the figure, the steel cable anchor 1 is a steel rod, which is buried in the slope protection area. One end of the steel cable anchor is provided with a steel cable anchor ring 8 exposed on the slope surface, and the other end is a steel cable anchor. The tail is buried inside the slope; the steel cable anchors are arranged in a square with four steel cable anchors as a protective grid unit. The lateral support rope 3 is connected; the protective net against falling rocks of the slope is formed by connecting together se...

Embodiment 2

[0041] The construction method of the protective net for slope rockfall prevention of the present invention is characterized in that comprising the following steps:

[0042] a. Clean up the slope: Manually remove the floating soil and pumice in the slope protection area, and properly trim the local terrain (local accumulations and protrusions, etc.) that is not conducive to construction and installation and affects the normal function of the system after installation.

[0043] b. Set-out measurement to determine the hole position of the steel cable anchor, with a vertical and horizontal distance of 4.5 meters, and dig a pit at each hole with a depth not less than the length of the exposed ring of the steel cable anchor, generally 20 cm in diameter and 20 cm deep.

[0044] c. Drill the steel cable anchor hole according to the design depth and clear the hole. The hole depth should be more than 5cm longer than the designed steel cable anchor length, and the hole diameter should no...

Abstract

A slope anti-rockfall guard net comprises cable anchor poles (1), cable nets (4) and steel wire meshes (5); the cable anchor pole (1) is a steel rod, and buried in a slope protection area; the steel wire mesh (5) is paved on a protection grid cell, close to a slope surface, and binding wires can tie and fix the steel wire mesh with vertical support ropes (2) and transverse support ropes (3); the cable net (4) is paved on the top surface of the steel wire mesh(5), and stitching ropes can stitch the cable net with vertical support ropes (2) and transverse support ropes (3). The slope anti-rockfall guard net and a construction method thereof are reasonable in guide net preparation step design, simple in operation, and the prepared guide net is strong and durable, obvious in effect, can intercept road slope rockfall, thus reducing rockfall damages in the road usage process.

Description

technical field [0001] The invention relates to a protective device for preventing falling rocks on a slope, in particular to a protective net and a construction method for preventing falling rocks on a road slope. Background technique [0002] my country is a mountainous country, and there are many sections passing through mountainous areas in road construction. Due to the broken rock mass in some areas, or the rolling of gravel due to the erosion of rainwater, it will cause harm to vehicles running normally on the road. The harm caused by rolling rocks on the side slope has become one of the main reasons affecting the normal operation of the expressway. In recent years, both at home and abroad, manual removal of dangerous rocks or the method of dragging and guiding to prevent falling into the net have been adopted. However, the method of manually removing dangerous rocks is dangerous and expensive, while the method of using the method of pulling and guiding to prevent fall...
