Embodiment Construction

[0034] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0035] As shown in the figure, the high slope bolt and cable work platform includes a lifting operation platform. The lifting operation platform is composed of a platform frame and two "K" type lifting frames 1. The two "K" type lifting frames 1 are respectively The sides symmetrical to the bottom surface of the platform frame are connected; the "K" type lifting frame 1 is composed of a vertical arm 2, a horizontal telescopic arm 3 and an oblique telescopic arm 4; the oblique telescopic arm 4 is provided with three telescopic fixed nuts 5, According to different grades, through the telescopic rods of the oblique telescopic arm 4 and the horizontal telescopic arm 3, effective contact with high slopes with different grades can be achieved; the top of the "K" erecting arm 1 is provided with a roller 6;

[0036]It also includes the horizo...

Abstract

The invention discloses a high slope bolt and cable operation platform and a construction method. The high slope bolt and cable operation platform is mainly structured in that a slope crest horizontalrail and a slope bottom horizontal rail are paved on the slope crest and the slope bottom of a high slope, separately, and meanwhile, two slope guide rails are paved on the slope surface to form a slope rail sliding system. Bolt and cable operations of the high slope are finished under the action of a guide rail system through a self-made K-shaped lifting rack with horizontal and oblique telescopic arms. The construction method comprises the following steps of first, forming bolt and cable drilling points by means of a total station with a laser collimation device; and then mounting a bolt and cable down-the-hole drill on the K-shaped lifting rack capable of stretching freely to fit different slope rates. Under the action of the guide rail system, the technical problem about how to efficiently finish related construction in the high slope bolt and cable construction operation can be solved freely, automatically and excellently along the slope surface.

Description

technical field [0001] The invention belongs to the field of high slope construction in road engineering, and in particular relates to a high slope bolt and anchor cable operation platform and a construction method. Background technique [0002] With the development of society, most municipal roads in the city can no longer meet the traffic volume requirements. After road reconstruction, the roads are gradually widened to both sides. When disasters such as weathering and spalling, flowing rocks and mud, falling stones, collapses, and landslides occur on slopes, it is necessary to strengthen and protect high slopes. Anchor anchor cables and frame beam protection have become an effective technology for high slope support. Measures and important technical means. Currently, the commonly used working platform for bolting and anchoring cables is to build steel pipe scaffolding. The installation and dismantling period is long, the cost is large, and the safety factor is not high, w...
