Embodiment 1

[0042] refer to figure 1 , figure 2 , Figure 8, a multi-span continuous lifeline device in this embodiment, comprising two anchor piers 1 provided with anchor rings 5, several pier piers 2 arranged between the two anchor piers 1, upright columns 3 arranged above the pier piers 2, And the steel wire rope 6, the steel wire rope 6 is passed through the upper part of the column 3, and the two ends of the steel wire rope 6 are respectively connected with the anchor ring 5.

[0043] A kind of multi-span continuous lifeline device of this embodiment, when in use, at first excavates the pier hole under the complicated environment such as Dan Xiayan mountaintop cliff topography, then set anchor pier 1 and column pier 2 in the pier hole, make the anchor pier The pier 1 and the column pier 2 can be more firmly fixed in a complex environment, thereby greatly increasing the reliability of the lifeline device in a complex environment and improving the safety of working at heights.

Embodiment 2

[0056] This embodiment provides a construction method for the multi-span continuous lifeline device described in Embodiment 1.

[0057] The technical scheme of the construction method of the multi-span continuous lifeline device of the present embodiment is as follows, comprising the steps:

[0058] The first step is to measure and set out the line according to the topography of the cliff top, and locate the anchor pier 1 and the column pier 2; the anchor pier 1 is located at a distance of 3m outside the column pier 2 at both ends, and the distance between each column pier 2 is 10m;

[0059] The second step is to excavate the pier pit according to the positioning position and size of the anchor pier 1 and the column pier 2;

[0060] The third step is to support the formwork at the pier pit and perform pouring to form the anchor pier 1 and the column pier 2 with the anchor ring 5; the anchor pier 1 and the column pier 2 can be poured with C30 concrete; the lower part of the anc...

Abstract

The invention provides a multi-span continuous lifeline device and a construction method thereof, so that the lifeline can be more reliably installed, and the safety of aerial work is improved. According to the technical scheme of the multi-span continuous lifeline device, the multi-span continuous lifeline device comprises two anchor piers which are provided with anchor rings, a plurality of column piers arranged between the two anchor piers, columns arranged above the column piers and a steel wire rope, wherein the steel wire rope penetrates through the upper part of the columns, and the twoends of the steel wire rope are respectively connected with the anchor rings. According to the multi-span continuous lifeline device, when the multi-span continuous lifeline device is used, pier pitsare firstly excavated in a complex environment such as a Danxia rock cliff edge terrain, then the anchor piers and the pillar piers are arranged in the pier pits, and the anchor piers and the columnpiers can be more firmly fixed in a complex environment, so that the reliability of the lifeline device in a complex environment is greatly improved, and the high-altitude operation safety is improved.

Description

technical field [0001] The invention relates to the technical field of border fall prevention for high-altitude operations, in particular to a multi-span continuous lifeline device and a construction method thereof. Background technique [0002] With the continuous improvement of construction technology, more and more attention has been paid to the safety of high-altitude operations in complex environments. At present, the safety of working at heights can be improved by erecting lifelines. [0003] Lifelines are mainly used in construction sites such as steel structures and power towers, and are mainly divided into vertical lifelines and horizontal lifelines. Wherein, the horizontal lifeline is fixedly erected on the side of the building facade through a fixed support, or erected on the upper part of the main beam wing edge of the steel structure by using a tripod. [0004] Existing lifelines can be well applied to environments with reliable buildings, but in complex envir...
