Summary of the invention
Technical problem to be solved by this invention is, there is provided a kind of to connect by vertical shaft, main equipment room is arranged in underground, optimize the arrangement of fixed end and main equipment room, under the prerequisite meeting safe operation, solve the technical barriers such as high cut slope excavation, supporting and environmental protection, significantly the arrangement of the high speed cable machine system on the high steep dam concrete dam of the Narrow Valleys of cost saving.
In order to solve the problems of the technologies described above, the technical solution used in the present invention is: the arrangement of the high speed cable machine system of the high steep dam abutment concrete dam of a kind of Narrow Valleys, high speed cable machine system comprise run crane across river cable, be positioned at the cable machine fixed end of side dam abutment for cable one end, fixed span river, be positioned at the cable machine mobile terminal of opposite side dam abutment and the main frame machine room of main frame pulling equipment is installed, described cable machine fixed end is fixed on outside the short adit of dam abutment top excavation, main frame machine room is arranged in underground by the guiding vertical shaft be arranged on below cable machine fixed end, main frame pulling equipment is connected with the guidance system be fixed on cable machine fixed end by guiding vertical shaft, run cable crane.
Be provided with dam crest curtain grouting gallery in the dam abutment of described concrete dam, main frame machine room is combined with dam crest curtain grouting gallery and arranges.
Be provided with concrete anchor hole formula fixed end in described short adit, described cable machine fixed end is arranged on the formula fixed end of concrete anchor hole.
The invention has the beneficial effects as follows: compared with the built hydroelectric project high speed cable machine arrangement of home and abroad, integral arrangement of the present invention is simple, smaller on the impact of height steep dam abutment monolithic stability, smaller to ambient influnence.Solve the technical barriers such as stability of high slope, excavation, supporting and environmental protection, significantly reduce engineering quantity and cost saving.
Accompanying drawing explanation
Fig. 1 is the schematic diagram of the arrangement of the high speed cable machine system of the high steep dam abutment concrete dam of Narrow Valleys of the present invention.
Fig. 2 is the partial enlarged drawing of Fig. 1.
Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the present invention is described in further detail:
The operating principle of high speed cable machine system of the present invention is identical with prior art, can with reference to prior art, so no longer describe.The present invention and the difference of prior art are that the arrangement of high speed cable machine system is different, are described in detail below:
As Fig. 1, shown in 2, the arrangement of the high speed cable machine system of the high steep dam abutment concrete dam of Narrow Valleys of the present invention, high speed cable machine system comprise run crane across river cable 1, be positioned at the cable machine fixed end 2 of side dam abutment 9 for 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 main frame pulling equipment is installed, described cable machine fixed end 2 is fixed on outside the short adit 10 of dam abutment top excavation, main frame machine room 3 is arranged in underground by the guiding vertical shaft 5 be arranged on below cable machine fixed end 2, main frame pulling equipment is connected with the guidance system 6 be fixed on cable machine fixed end by guiding vertical shaft 5, run cable crane.
Be provided with dam crest curtain grouting gallery 7 in the dam abutment 9 of described concrete dam, main frame machine room 3 is combined with dam crest curtain grouting gallery 7 and arranges.
Be provided with concrete anchor formula fixed end 4 in described short adit 10, described cable machine fixed end 2 is arranged on concrete anchor formula fixed end 4.
Be described below in conjunction with specific embodiment:
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, project playout 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 the technical barriers such as the stable and strengthening supporting of high cut slope excavation, also need significantly to increase construction investment.
Adopt the arrangement of high speed cable machine system of the present invention, combined by cable machine host machine room with dam crest curtain grouting gallery, underground type main frame machine room is helped in design, is connected with anchor hole formula fixed end by the guiding vertical shaft of nearly 50m, shape cable-former system.
