Description
Technical field
The utility model relates to a kind of anti-skid structures of rock-fill dams spillway on dam body, belong to hydraulic and hydroelectric engineering hydro-structure skill
Art field.
Background technique
Rock-fill dams spillway on dam body can effectively avoid bank slope formula spillway heavy excavation and issuable high slope treatment from asking
Topic, while construction investment is reduced, how to solve the problems, such as that its antiskid is particularly significant.
Slot segmentation mainly will be let out using aeration slot both at home and abroad at present, each section of bottom plate uses stacked tile type construction to connect in the longitudinal direction
It connects, i.e., upper section bottom plate and lower section bottom plate are overlapped in aeration slot and choose under bank and form transverse joint.Slot is let out for reinforcement to connect with rockfill,
A horizontal anti-slide slab is set on the top of every section of aeration slot, and level gos deep into enrockment dam body, then with the reinforcing bar for being surrounded by fines concrete, anchor
It is fixed in rockfill, specific structure is as shown in Figure 1；Its main feature is that by horizontal anchor structure by chute bottom slab " suspension " in enrockment
On the dam slope of downstream.
In the prior art, many medium and small project vent flows are small, and flow velocity is little, consider from hydraulics merely, no
It will appear cavitation corrosion, do not need setting aeration slot, one kind as disclosed in the Chinese patent application No. is 2016214517893 is overflow big vast
Road.And it is current let out slot stacked tile type segmentation connection need to be using aeration slot, therefore the effect of aeration slot fails to make full use of, and being arranged should
Structure can also improve difficulty of construction, while the anti-skid plate being arranged is thin-slab structure, and enrockment in its vicinity rolls need to be using artificial
It is backfilling and compacted, is not easy to construct, be easy to produce weak link in the area, such as application No. is 2005200147197 Chinese patent public affairs
The reinforced concrete face rockfill dam spillway on dam body opened.
Utility model content
