Description
Technical field
The utility model relates to construction of hydropower plant, refers to the large span adhesive tape conveyor trestle keeping the natural overcurrent form of coombe especially.
Background technology
Nearly ten years, China's hydroelectric project major part concentrates on deep mountain valleys area, southwest, and general sandstone stock ground, dam main raw material(s) supply place or Preservation for Aggregate Production System position are comparatively far away apart from dam construction district, need build special long distance adhesive tape conveyor sand transportation building stones.Adhesive tape conveyor paddy gully along the line is grown thickly, and adhesive tape conveyor needs frequent leap mountain valley coombe.It is steep that southwest narrow valley region coombe generally has ditch depth slope, and the large even association mud-rock flow secondary disaster of run-off in rainy season occurs, and dry season with the feature that larger crosscut wind produces, has a negative impact to the safe operation of adhesive tape conveyor again.Phase of the executing Preservation for Aggregate Production System in the black East Germany power station of my institute's design, all there is above-mentioned geographic and geomorphic conditions in the adhesive tape conveyor participating in the sand transportation building stones of the Pubugou Hydropower Station, imperial opening power station etc. of the Jinping Hydroelectric Power Station of sandstone system, Xiangjiabahydropower project, Xi Luo Du reservoir, power station, white crane beach and Da Gang Mountain power station and the design of other unit.Guarantee that adhesive tape conveyor is safe and reliable, the span structure of adhesive tape conveyor as far as possible directly should cross over coombe, therefore the selection across groove structure form is very important, and on the selection of transporter overall plan, it determines that impact is comparatively large, be the controlling project of adhesive tape conveyor design.
According to statistics in above-mentioned engineering, sealing-tape machine supply line circuit longest distance is 39Km, and the shortest is 4.5Km, needs the span scope crossing over coombe on the way between 30 ~ 60m, the coombe degree of depth 20 ~ 90m.Wherein the coombe span of 60m is far beyond the conventional adhesive tape conveyor structural span of current domestic water electrical engineering.And existing adhesive tape conveyor girder truss span is generally within 24m, 30m is comparatively rare with upper span.
And the large span sealing-tape machine of conventional art generally needs to arrange the structure such as column, buttress sub-truss beam in coombe.Support the flow section area that structure not only reduce coombe, also can form stop to advancing of mud-rock flow, and then the safe operation of adhesive tape conveyor is had a negative impact.
Utility model content
The purpose of this utility model is to overcome that the deadweight of existing large span trestle is excessive, high cost and the large span adhesive tape conveyor trestle of the natural overcurrent form of maintenance coombe that provides.
The utility model realizes by following technical scheme:
Keep the large span adhesive tape conveyor trestle of the natural overcurrent form of coombe, comprise the tower foundation and girder truss be located in coombe both sides; Described tower foundation is fixed on ground by inner side anchor pole group; Described tower foundation arranged outside has strainer basis; Described strainer basis is fixed on ground by outside anchor pole group;
Described girder truss two ends are hinged with the described tower foundation of both sides respectively, and described girder truss is across coombe; Rubber conveyer is provided with in described girder truss; Described girder truss length is 50-70m;
Described tower foundation is provided with pylon; Described pylon top is provided with pulley; Described strainer basis is provided with strainer, and described strainer basis is connected with one end of some wire rope by described strainer; Described wire rope and described pulley are slidably matched; Described girder truss is made up of some sections of girder truss standard knots, and adjacent described girder truss standard knot is connected by connection segment frame; Described connection segment frame is provided with wire rope hole; The other end of described wire rope is connected with described wire rope hole.
Described girder truss height is 2-2.5m.
Maintenance channel is provided with in described girder truss.
Preferably, described girder truss length is 50-70m.
The utility model utilizes the pylon being fixed on coombe two sides, adopts wire rope inclined-pulling girder truss.To the large-span truss beam of coombe two sides be supported in, by the oblique pull of several wire rope be connected with beam, for span structure provides multiple fulcrum, single beam be become continuous beam on many supports.Wire rope is fixed on the anchor beam on bank by strainer after then being altered course by the pylon being arranged in coombe two sides.
The utility model proposes and use adhesive tape conveyor to transport leap large span coombe sand material, the adhesive tape conveyor trestle adopted is by the mode of wire rope inclined-pulling girder truss, namely wire rope one end is connected with girder truss, and the other end is fixed on the ground of two sides after being altered course by the pylon being arranged at coombe two sides.Without the need to arranging the structure of any lattice beam in coombe, keeping the natural overcurrent mode of coombe, being specially adapted to southwestern narrow valley region coombe.It is steep that southwest narrow valley region coombe generally has ditch depth slope, the feature that the large even association mud-rock flow secondary disaster of run-off in rainy season occurs.
Trestle truss depth of beam is comprehensively determined according to span size, stressed size and technological requirement etc.The rise-span ratio of general simple truss beam gets 1/12 ~ 1/15.For 60m span, truss deck-molding h=5 ~ 4m.Adopting the mode of wire rope inclined-pulling girder truss across coombe adhesive tape conveyor trestle, is 2m by the height reduction of girder truss, corresponding rise-span ratio 1/30.The girder truss cross dimensions of design meets technique Clearance requirement, without the need to because of span size, stressed size and increase deck-molding.Meanwhile, girder truss height is reduced to 2m by 5 ~ 4m, greatly reduces the steel using amount of web member, diagonal web member and montant, has good economy.
Girder truss profile height is little, is made up of multiple standard knot.Structure and component simple, light, easily transport, be convenient to oblique pull method assembled, be easy to install, reinforce and reconstruction.Not by landform and the impact in season.The junction of wire rope and each standard knot of girder truss arranges connection segment frame, can arrange stiffener easily in steel pipe, to ensure the Strength Safety of junction.Wire rope permissible stress is very high, and connecting structure between girder truss is succinct, convenient, to girder construction without any weakening.Wire rope and girder truss supporting the use on the adhesive tape conveyor trestle crossing over coombe, accomplish to make the best use of everything very easily.
