Description
Technical field
The present invention relates to water conservancy and hydropower equipment technical field, particularly relate to a kind of power transmission stool.
Background technology
Concrete Face Rockfill Dam take rockfill as supporting construction, and surperficial concreting panel is as the loose rock dam of leakage preventing structure at its upstream, is called for short rock or face dam.Concrete Face Rockfill Dam its belong to earth and rockfill dam type.
Concrete Face Rockfill Dam grows up after the sixties.Sloping core (or panel) loose rock dam impervious body is positioned at rockfill upstream, and material has earth material, steel concrete, bituminous concrete, timber etc.The antiseepage soil body can be placed on rockfill upstream, also can arrange thicker heap rock layers on native sloping core.Concrete Face Rockfill Dam is primarily of rockfill and seepage control system composition, and namely specifically Concrete Face Rockfill Dam is generally made up of following structure: namely concrete slab (or being called for short panel), toe board, bed course, transition zone, main rockfill area, secondary rockfill area form (as shown in Figure 1).
But, because 300m level conventional panels dam exists a lot of technical problem: for 300m level Concrete Face Rockfill Dam, because dam increases, panel plagioclase increases, water pressure increases, if the form of structure of the panel that follows conventional lines, upper deck panels to the cumulative stress of lower floor's panel by corresponding increase, this will worsen the stress state of lower floor's (particularly bottom) panel, and counter plate material property will propose higher requirement.Secondly, dam increase cause dam body filler be out of shape increase, the distortion that dam body is larger will cause the corresponding increase of distortion of its attachment panel, thus extruding between generation panel, bend, fracture, faulting of slab ends, the distortion such as to tear, add the acting in conjunction of water pressure load, the panel power transmission supporting system on conventional panels dam more and more not very heavy burden.
In addition, as can be seen from both at home and abroad built, design in the panel arrangement of the 150m ~ 300m level face dam built or plan to build, current conventional method is all mat formation " Transition Materials+bedding material+panel+local bedding material " successively at main rockfill upstream dam facing, be aided with the joint seal design between panel and location plate seepage prevention design again, the entirety defining conventional panels dam prevents blending water-retaining structure.Conventional panels dam is all be supporting construction with rockfill, using concrete slab as leakage preventing structure.And due to the tired block mode of concrete slab upper and lower deck panels from bottom to top, lower floor's panel in fact also becomes the supporting construction of upper deck panels.The disadvantage that conventional panels dam exists is exactly the tired block support pattern of upper deck panels pressure deck panels.Under gravity, panel successively superposes will the stress of panel be caused to worsen along the weight component of dam facing, and increases with dam body height, and water pressure and deadweight component increase, and panel force-bearing situation causes anxiety.
I takes charge of and proves through large quantity research subsequently, propose a kind of panel support structure mentality of designing being adapted to 300m level face dam newly, namely in adjacent any two pieces of panel partitioned organizations: upper deck panels (i.e. upper strata concrete slab), a kind of load transfer device is designed between lower floor's panel (i.e. lower-layer concrete panel), and be fixed in loose rock dam through anchor structure, and then improve upper deck panels, (the deadweight component being parallel to panel namely utilizing load transfer device to be born by concrete slab is delivered on anchor structure the stressing conditions of lower floor's panel, and then by anchor structure, stable fixing is implemented to concrete slab).
