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 realized; the top of the vertical arm 1 is provided with a roller 6;

[0036]It also includes the horizontal...

Abstract

The invention discloses a bolt and cable work platform for a high slope and a construction method thereof. The work platform for the bolt and cable mainly lays horizontal rails at the top and bottom of the slope at the top and bottom of the high slope, respectively. At the same time, two slope guide rails are laid on the slope to form a slope track sliding system. The self-made "K" type lifting frame with horizontal and oblique telescopic arms is used to complete the bolt and cable work on high slopes under the action of the guide rail system. The construction method is firstly to place the anchor rod and anchor cable drilling point through the total station with laser aiming device, and secondly to install the anchor rod and anchor cable down-the-hole drilling rig on the "K" type lifting frame that can freely expand and contract to adapt to different slope ratios. , under the action of the guide rail system, it can freely and automatically along the slope to solve the relevant construction technical problems in how to efficiently complete the construction of anchor bolts and cables on high slopes.

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...
