Compared with the prior art, the invention has the beneficial effects that: when the method is adopted for installing the line support, the simple temporary cargo rope bearing rope is only required to be constructed by utilizing the existing cableway, so that the material is conveyed through the simple temporary cargo rope bearing rope, the installation process of the line support is more convenient, and the convenience for installing the line support in the cliff area is improved.
Detailed Description
Firstly, mounting a bracket: firstly, a nylon wire with the diameter of 2.5mm is discharged to a station on the cableway by an unmanned aerial vehicle along the cableway line, then a nylon rope with the diameter of 6mm connected with the tail end of the nylon wire with the diameter of 2.5mm is pulled to the station along the cableway line by a 3T winch at the station, a working steel wire rope with the diameter of 9.3mm is pulled to the station along the line by the nylon rope with the diameter of 6mm, and a working steel wire rope with the diameter of 9.3mm at the other side of the central line of the cableway is discharged in the same way. According to the line terrain of the cableway, a simple herringbone support is manufactured at a favorable support point position by utilizing two steps of taking or on-site trees, a working steel wire rope with the diameter of 9.3mm penetrates through a temporary roundabout wheel of a station, the working steel wire rope is knitted and closed to form a circulating temporary traction rope, meanwhile, the temporary traction rope is hung in a rope supporting wheel groove of the simple support along the line, then the working steel wire rope with the diameter of 15.5mm is pulled to the station through the temporary traction rope with the diameter of 9.3 to serve as a simple temporary cargo rope bearing rope, the bearing rope is tensioned and fixed, and after a small roadster is hung, the simple temporary cargo rope installation is preliminarily completed.
And secondly, starting to transport and install a first formal cargo cable support from the lower station in sequence:
1) the upright columns, the cross beams, the cable ropes and the like of the support are transferred from the centralized stockyard to a cargo cable loading point or the side of a road closest to the support point through a truck-mounted crane, and then are transported to a line through a simple temporary cargo cable;
2) mounting a stand column:
the first step is as follows: and selecting the position of the upright post and the cable wind rope ground anchor. According to the field conditions, the standing position of an upright post of the temporary cable support is determined by measuring through a total station, a wood board or a steel plate is paved after leveling and tamping, and meanwhile, a proper natural anchor pile, a big tree or a whole rock with a proper shape is selected as far as possible in the upper and lower station directions of the cross line of the upright post; under the condition of no natural ground anchor, a small-sized fully-buried ground anchor can be manufactured manually according to the stress of the guy rope to serve as an anchor pile of the guy rope; and under the condition that the periphery of the anchor pile is provided with rock without anchor points, only the anchor rod can be drilled on the rock to be used as an anchor pile of the guy rope.
The second step is that: the upright post is installed by means of the slope terrain of the installation point, and the lower end of the upright post is fixed by a chain block for preventing the upright post from sliding downwards. And fixing four corresponding guy cables at the upper end of the upright post. The vertical column is slowly pulled up by the chain block in the lower station direction, and the other three guy cables are balanced in direction mastered by force.
The third step: and hoisting another upright post by using the upright post which is erected, and then repeating the second step.
The fourth step: and the two upright posts are adjusted to proper positions by using the guy cables so as to facilitate the installation of the cross beam.
3) Mounting a cross beam: and mounting a small holding pole at the top ends of the two upright posts which are completely stood as a lifting point of the chain block, and slowly lifting the cross beam. And after the beam flange is in place, the beam flange is fixedly connected with the upright column flange by bolts. And (5) removing the cable rope on the inner side of the door-shaped frame after the installation is finished.
4) The cable wind rope sets up: the standing angle of the portal frame is adjusted by 6 wind cables with the diameter of 15.5mm at the top of the portal frame to be perpendicular to the bearing cable as far as possible, and after the portal frame is adjusted, the wind cables of the ground anchor cables in 6 directions are tensioned and locked and fixed by a rope clamp, and then the 3T chain block is detached. The support higher than 15m is fixed by double-layer guy rope and waist rope.
