In described short adit, be provided with concrete anchor hole formula fixed end, described cable machine fixed end is arranged on the formula fixed end of concrete anchor hole.
The beneficial effects of the utility model are: compare with home and abroad built hydroelectric project high speed cable machine layout pattern, the utility model integral arrangement is simple, smaller on the steep dam abutment monolithic stability impact of height, smaller to ambient influnence.Solve the technical barriers such as stability of high slope, excavation, supporting and environmental protection, significantly reduced engineering quantity and cost saving.
Accompanying drawing explanation
Fig. 1 is the high schematic diagram of the layout pattern of the high speed cable machine system of dam abutment concrete dam suddenly of Narrow Valleys of the present utility model.
Fig. 2 is the partial enlarged drawing of Fig. 1.
The specific embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail:
The operating principle of high speed cable machine system of the present utility model is identical with prior art, can be with reference to prior art, so no longer narration.The utility model and the difference of prior art are that the layout pattern of high speed cable machine system is different, are described in detail below:
As Fig. 1, shown in 2, the layout pattern of the high speed cable machine system of the high steep dam abutment concrete dam of Narrow Valleys of the present utility model, high speed cable machine system comprise operation crane across river cable 1, be positioned at a side dam abutment 9 for the cable machine fixed end 2 of cable one end, fixed span river, be positioned at the cable machine mobile terminal 12 of opposite side dam abutment and the main frame machine room 3 of installation main frame pulling equipment, described cable machine fixed end 2 is fixed on short adit 10 outsides of dam abutment top excavation, main frame machine room 3 is arranged in underground by being arranged on the guiding vertical shaft 5 of cable machine fixed end 2 belows, main frame pulling equipment is connected with the guidance system 6 being fixed on cable machine fixed end by guiding vertical shaft 5, operation cable crane.
In the dam abutment of described concrete dam 9, be provided with dam crest curtain grouting gallery 7, main frame machine room 3 is arranged with 7 combinations of dam crest curtain grouting gallery.
In described short adit 10, be provided with concrete anchor formula fixed end 4, described cable machine fixed end 2 is arranged on concrete anchor formula fixed end 4.
Below in conjunction with specific embodiment, describe:
Some hydropower station barrage is compaction type concrete gravity dam, and two sides mountain shape is grand, and mountain top, left bank elevation extends to 2450m, and right bank is 2150m.Two sides landform is grown without large-scale coombe, and two sides, river valley symmetry is fair, and the left bank gradient is generally the basement rock abrupt slope of 50～75 °, slope Gao Keda 1000m.Right bank is the one side hillside of 40～50 °, slope Gao Keda 400m.Because this upstream, power station is arranged in deep mountain valleys, by current home and abroad common practice, cable machine arrangement can only be selected in parallel-moving type or radiant type.Consider that landform, geology, hinge arrangement condition and construction need, radiant cable crane is arranged routinely, for meeting fixed end and main frame division of room, need to excavate on a large scale two sides massif, except bringing high cut slope excavation stablize and add the technical barriers such as strong supporting, also need significantly to increase construction investment.
