Description
Technical field
The present invention relates to a kind of anti-skid structures of rock-fill dams spillway on dam body, belong to hydraulic and hydroelectric engineering hydro-structure technology neck
Domain.
Background technology
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., epimere bottom plate is overlapped in aeration slot with hypomere bottom plate and chooses 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, concrete 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, considers from hydraulics merely, no
It will appear cavitation corrosion, aeration slot need not be set, a kind of flood that overflows as disclosed in the Chinese patent application No. is 2016214517893
Road.And it is current let out slot stacked tile type segmentation connection and need to utilize 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, enrockment in its vicinity roll need to use it is artificial
It is backfilling and compacted, is not easy to construct, weak link is easy tod produce in the area, such as application No. is 2005200147197 Chinese patent public affairs
The reinforced concrete face rockfill dam spillway on dam body opened.
Invention content
In order to solve the above technical problems, the present invention provides a kind of anti-skid structure of rock-fill dams spillway on dam body, the rock-fill dams
The anti-skid structure of spillway on dam body is not provided with aeration slot, reduces the difficulty of construction of spillway on dam body, while ensureing that enrockment fills close
Solidity avoids above-mentioned various problems.
The present invention is achieved by the following technical programs.
A kind of anti-skid structure of rock-fill dams spillway on dam body provided by the invention, including upper chute bottom slab, reinforced concrete anchors

Lower chute bottom slab is equipped in the side of upper chute bottom slab and lower chute bottom slab by junction of the edges of two sheets of paper bar connecting and lets out trough rim wall, the other side
Equipped with anti-skid foot；The slot transverse joint of letting out is fold-type, and the epimere for letting out slot transverse joint is vertically arranged in and lets out trough rim within the walls, lets out under slot transverse joint
Section is vertical with upper chute bottom slab, is arranged between upper chute bottom slab and lower chute bottom slab；One side of the anti-skid foot with above let out slot
Bottom plate connects, and another side is connect with lower chute bottom slab；The armored concrete anchor beam is connect by anchor lacing wire with lower chute bottom slab.
The anti-skid foot is the anti-skid foot of V-groove, and anti-skid foot is on one side vertical plane, is connect with upper chute bottom slab, another side
For horizontal plane, it is connect with lower chute bottom slab.
The length of side of the anti-skid foot horizontal plane is equal with the thickness of upper chute bottom slab, lower chute bottom slab.
The connecting portion on one side that the upper chute bottom slab is connect with anti-skid foot is filled with pitch.
The anchor lacing wire is that " [" shape, one end of anchor lacing wire and lower chute bottom slab reinforcement welding, the other end are inserted into reinforced concrete
In native anchor beam.
The surface of the anchor lacing wire is socketed with stainless steel tube, and there are gaps between anchor lacing wire and stainless steel tube.
Mortar is filled in the gap.
The junction of the edges of two sheets of paper reinforcing bar not with let out slot contraction joint contact.
The beneficial effects of the present invention are：
1. cancelling aeration slot structure, for small flow, the spillway required without cavitation prevention, structure is relatively easy；
2. upper and lower chute bottom slab upstream face flushes, flow condition is preferable；
3. construction investment can be reduced by reducing aeration slot and anti-skid plate.
