Description
Technical field
The utility model relates to a kind of crag cabling arrangements, particularly a kind of crag cabling arrangements being applied to Hydraulic and Hydro-Power Engineering technical field.
Background technology
In Hydraulic and Hydro-Power Engineering, because cable trough is the necessary building of Hydraulic and Hydro-Power Engineering, and being arranged on each main building, is the basis of power station to inside and outside transmission line.Comparatively complicated in the more difficult cable laying condition of passing through area such as precipitous crag, cable laying can only be changed its course the circuit that detours usually, or manually carry out cable laying by taking simple and easy steelframe at present, construction plan has that cost is high, manufacture difficulty is large, the shortcomings such as inconvenient are brought to engineering construction and maintenance, in recent years along with development, the progress of society, to the raising of the normal service requirement of engineering and the change of design concept, more increasing Hydraulic and Hydro-Power Engineering is difficult to pass through area in cable laying, and cable system design originally cannot realize.Therefore also there is no in prior art that a kind of cost is low, manufacture difficulty is little, facilitate the crag cabling arrangements of engineering construction and maintenance.
Utility model content
Technical problem to be solved in the utility model is to provide that a kind of cost is low, manufacture difficulty is little, facilitates the crag cabling arrangements of engineering construction and maintenance.
For solving the problems of the technologies described above, the crag cabling arrangements that the utility model adopts, comprise crag and overarm, described overarm side is fixedly connected with crag, and described overarm is provided with groove.
Further, described overarm is reinforced concrete structure.
Further, gutter is provided with between groove and crag.
Further, described gutter is surrounded by the rectangular indentation on hanging oneself from a beam and crag.
Further, the width in described gutter is greater than or equal to 400mm.
Further, the lower surface of described overarm is inclined-plane, and the angular range of described inclined-plane and horizontal plane is 25 degree to 30 degree.
Further, also comprise anchor pole, described anchor pole one end anchors in crag, and one end is fixed in overarm.
Further, three row's anchor poles are had from gutter to overarm lower surface directional spreding.
Further, described overarm is segmental structure.
Further, structural joint is provided with between described adjacent two sections of overarms.
The beneficial effects of the utility model are: the suspension beam structure arranged on precipitous crag defines suspended cable ditch, solve that a lot of cable is more difficult passes through area, ran into precipitous crag cable laying before changing usually can only to change its course the circuit that detours, increase line length, increase cost, present connection precipitous crag two ends cable louding, by arranging suspended cable ditch on precipitous crag, bring convenience to cable laying, also potential safety hazard is relieved, decrease line arrangement length, reduce investment outlay, the present invention has the advantages such as cost is economized, maintenance is convenient.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the schematic diagram of steel bar arrangement;
Fig. 3 is the schematic diagram that cable lays along crag;
Parts, position and numbering in figure: crag 1, overarm 2, groove 3, gutter 4, the width D in gutter, lower surface 5, anchor pole 6, structural joint 7, reinforcing bar 8, cable 9.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail.
As shown in Figure 1, Figure 2 and Figure 3, crag cabling arrangements of the present utility model, comprise crag and overarm 2, described overarm 2 side is fixedly connected with crag, and described overarm 2 is provided with groove 3.Beam side is fixedly connected with crag, and opposite side is the unsettled setting in side near a river.The groove 3 that overarm 2 is arranged is used for placing cable 9.Because groove 3 is along the trend of crag, therefore cable 9 can lay along crag, and does not need to get around the more difficult areas of passing through such as precipitous crag, shortens the length of circuit, reduces engineering cost.
Described overarm 2 is reinforced concrete structure.In order to ensure the intensity of structure, convenient construction, overarm 2 adopts concrete-steel structure.Reinforcing bar 8 is arranged along the cross-sectional direction of overarm 2.
Gutter is provided with between groove 3 and crag.In order to get rid of the ponding flowed down along crag in time, protection cable 9, is provided with gutter between groove 3 and crag.
Described gutter is surrounded by the rectangular indentation of hanging oneself from a beam on 2 and crag.For the ease of construction, save material, utilize crag as a sidewall in gutter, jointly surround gutter with the rectangular indentation in overarm 2.
The width D in described gutter is greater than or equal to 400mm.In order to ensure that gutter can drain the water away in time, preventing rainwater from overflowing from ditch, making the width D in gutter be greater than or equal to 400mm when designing.
The lower surface 5 of described overarm 2 is inclined-plane, and the angular range of described inclined-plane and horizontal plane is 25 degree to 30 degree.Lower surface 5 is inclined-plane, can reserve operating space, constructability for construction.
Also comprise anchor pole 6, described anchor pole 6 one end anchors in crag 1, and one end is fixed in overarm 2.Anchor pole 6 is used for being connected to overarm 2 with crag 1 machine and reinforcing.
Three row's anchor poles 6 are had from gutter to overarm 2 lower surface 5 directional spreding.The arrangement of three row's anchor poles 6 can be that overarm 2 is more firm with the connection of crag 1.
Described overarm 2 is segmental structure.Overarm 2 is convenient to section construction for segmental structure.
Structural joint 7 is provided with between described adjacent two sections of overarms 2.Structural joints 7 between adjacent two sections of overarms 2 can to expand with heat and contract with cold leaving space for overarm 2, prevent overarm 2 from damaging because of variations in temperature.
Structural design adopts crag hanging beam method for designing to carry out, and mainly drafts cross dimensions according to engineering actual landform, feature and adjusts by bracket theoretical test formula, then carries out steel bar stress 8, fixing anchor bar 6, the sliding stability Calculation of shearing resistance.Design principle carries out structural analysis by the Reinforced Concrete Corbels on scar, disregards cohesive force between concrete and scar, only considers the frictional force caused by normal pressure; Top anchor pole 6 is considered by axial tension component, only bears axial tension, does not bear shearing force; Bottom anchor pole 6 is not considered to bear outer lotus, is only used as additional fixing.Supporting needed for adjoining rock stability is separately considered to bear by system combined bolting and shotcrete.For ensureing cable trough structural safety, crag overarm 2 adopts three row's anchor poles 6 to reinforce, and anchor pole 6 size is determined according to calculating.
