Abstract
The utility model discloses a kind of arch dam table hole Segment gate bearing and top of arch dam tie-beam integrated structure, the Segment gate comprising Arch Dam, table hole overflow weir body and be arranged on the overflow weir body of table hole or support beam, supporting traverse is furnished with the Segment gate hinged-support for hinged Segment gate, and described supporting traverse is a part for Arch Dam.The utility model utilizes the three-dimensional-structure feature of arch dam, top of arch dam crossbeam or traffic structure and table hole supporting traverse is organically combined, and supporting traverse is not only as Segment gate braced structures on the one hand, but also takes into account table hole dam crest traffic; Supporting traverse is as an arch dam part on the other hand, arc door thrust can be distributed to two sides dam abutment by arching, alleviate the effect to gate pier, effectively improve the stress distribution of gate pier, avoids stress to concentrate, extends the metal construction life-span; In addition, because supporting traverse Bottom Altitude is high higher than water surface curve, therefore washing away of release floodwatering flow can be avoided.
Description
Technical field
The utility model belongs to Hydraulic and Hydro-Power Engineering dam technical field, relates to arch dam table pore structure and arranges, particularly relate to a kind of arch dam table hole Segment gate bearing and top of arch dam tie-beam integrated structure.
Background technology
In Hydraulic and Hydro-Power Engineering, table hole Segment gate braced structures generally adopts and arrange independent bracket as bearing on gate pier, and this seat structure subjects to release floodwatering flow and washes away, unfavorable to structure itself, and corrosion metals structure; When the arc door thrust that bearing bears is larger, neck produces stress and concentrates, and causes bracket, pier rehabilitation.Main in actual applications exist following deficiency:
(1) because arc door bearing and arch dam top cross-bar are independently arranged, locational space is very limited, cannot arrange bearing and top of arch dam crossbeam simultaneously; Part engineering adopts cancellation arch dam crossbeam only to arrange bearing, then owing to causing arch dam top arch to effect poor without arch to connection without more than table hole, add arch dam bottom stress;
(2) because arc door thrust directly acts on bearing/gate pier, neck produces stress and concentrates, and causes bracket, gate pier structure design difficulty very big, needs to configure a large amount of reinforcing bar, thus cause construction cost to increase.
Utility model content
The purpose of this utility model is to overcome the deficiencies in the prior art, a kind of arch dam table hole Segment gate bearing and top of arch dam tie-beam integrated structure are provided, this braced structures utilizes the architectural feature of Arch Dam, adopt supporting traverse structure as the braced structures of arch dam table hole Segment gate, replace conventional arched gate support, thus when avoiding the arc door thrust of bearing at bearing larger, neck produces stress and concentrates, and causes the phenomenon of bracket, pier rehabilitation.
The utility model is achieved by following technical solution.
A kind of arch dam table hole Segment gate bearing and top of arch dam tie-beam integrated structure, comprise Arch Dam, table hole overflow weir body and be arranged at the Segment gate on the overflow weir body of table hole, it also comprises supporting traverse, and supporting traverse is furnished with the Segment gate hinged-support for hinged Segment gate.
Described supporting traverse is a part for Arch Dam.
The Bottom Altitude of described supporting traverse is higher than water surface curve.
The beneficial effects of the utility model are:
Compared with prior art, braced structures described in the utility model is applicable to arch dam, this structure utilizes the three-dimensional-structure feature of arch dam, top of arch dam traffic structure and table hole supporting traverse are organically combined, supporting traverse is not only as Segment gate braced structures on the one hand, but also takes into account table hole dam crest traffic; Supporting traverse is as an arch dam part on the other hand, arc door thrust can be distributed to two sides dam abutment by arching, alleviate the effect to gate pier, effectively improve the stress distribution of gate pier, avoids stress to concentrate, extends the metal construction life-span; In addition, because supporting traverse Bottom Altitude is high higher than water surface curve, therefore can avoid washing away of release floodwatering flow, have broad application prospects.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
In figure: 1-Segment gate, 2-supporting traverse, 3-shows hole overflow weir body, 4-Segment gate hinged-support, 5-Arch Dam.
Detailed description of the invention
The technical solution of the utility model is further described below in conjunction with accompanying drawing, but described in claimed scope is not limited to.
As shown in Figure 1, a kind of arch dam table hole Segment gate bearing and top of arch dam tie-beam integrated structure, the Segment gate 1 comprising Arch Dam 5, table hole overflow weir body 3 and be arranged on table hole overflow weir body 3, it also comprises supporting traverse 2, support beam 2 is the braced structures of Segment gate 1, be again arch dam top connecting cross beam, as dam crest traffic, supporting traverse 2 can also be furnished with the Segment gate hinged-support 4 for hinged Segment gate 1.Braced structures described in the utility model is used in arc door 1 structural configuration of arch dam table hole, the supporting traverse 2 of Arch Dam 5 is adopted to replace traditional peripheral hardware Segment gate seat structure, Segment gate 1 is seated on overflow weir body 3, Segment gate hinged-support 4 is arranged on supporting traverse 2, as the braced structures of Segment gate thrust, described supporting traverse structure 2 is a part for Arch Dam 5.
The Bottom Altitude of described supporting traverse 2 is higher than water surface curve.Can effectively avoid washing away of release floodwatering flow like this.
