Description
Technical field
The invention belongs to water power hydraulic engineering technical field, in particular to a kind of slag structure and slag method.
Background technique
During building water conservancy project dam, a large amount of waste is often generated.These wastes require region to dissolve.
At this point, some natural gullies would generally be selected as slag tip, some gullies thus need additionally to increase far from construction area
The expenses such as expropriation of land immigrant, environmental protection, long distance transportation.
Summary of the invention
It is an object of the present invention in view of the above shortcomings of the prior art, a kind of slag structure and slag method, In are provided
The open riverbed in dam site downstream carries out slag, can reduce the cost generated by slag.
In order to solve the above technical problems, the technical scheme adopted by the invention is that:
A kind of slag structure is structurally characterized in that including being located at level of tail water rubble spats below, is located at the level of tail water or more
Rubble slope protection, rubble of the rubble spats by partial size in rock ballast greater than Φ fill and formed, remaining rubble in rock ballast is formed
Rubble slope protection；Rubble slope protection surface is laid with armoured concrete slab.
It further, further include geotextiles, rubble spats is set in geotextiles.
Further, weeper drain is equipped between rubble slope protection and armoured concrete slab.
Further, weeper drain protrudes into rubble slope protection, and weeper drain outsourcing geotextiles.
It further, further include being set to set on weeper drain outer end for fixing the steel wire of weeper drain and geotextiles
The sand for being used to wrap up weeper drain of weeper drain inner end.
Based on the same inventive concept, the present invention also provides a kind of slag methods, its main feature is that the following steps are included:
Step A, for being located at level of tail water position below, the rubble using partial size in rock ballast greater than Φ fills to form rubble shield
Foot；For being located at the position of the level of tail water or more, fill to form rubble slope protection using remaining rubble in rock ballast；
Step B is laid with armoured concrete slab on rubble slope protection surface.
Further, in step, for being located at level of tail water position below, one layer of geotextiles are first laid with, then fill
Rubble spats.
It further, further include that weeper drain is set between rubble slope protection and armoured concrete slab.
It further, further include setting geotextiles in weeper drain outsourcing, wherein weeper drain protrudes into rubble slope protection.
Further, before step A further include: clear up downstream river course original ground.
The solution have the advantages that: 1, cinder field be arranged in downstream river course, can reduce the expropriation of land of cinder field and its linking-up road
With immigrant etc. expenses；2, engineering excavation area is closed on, waste haul distance is reduced；3, implement simple draining and its safeguard procedures, subtract
Cinder field engineering protection amount is lacked；4, by backfilling rock ballast on downstream riverbank, slope surface has been modified, security performance is improved.
Detailed description of the invention
Fig. 1 is one embodiment of the invention structural schematic diagram.
Fig. 2 is the enlarged drawing in the portion A in Fig. 1.
Fig. 3 is the enlarged drawing in the portion B in Fig. 2.
Wherein, 1- original ground；2- rubble spats；3- armoured concrete slab；4- geotextiles；5- weeper drain；6- rubble shield
Slope；7- steel wire；8- sand.
Specific embodiment
As shown in Figure 1 to Figure 3, slag structure of the present invention includes being located at level of tail water rubble spats 2 below, is located at downstream
Rubble slope protection 6 more than water level, rubble of the rubble spats 2 by partial size in rock ballast greater than Φ are filled and are formed, its in rock ballast
Remaining rubble forms rubble slope protection 6；6 surface of rubble slope protection is laid with 3 mask of armoured concrete slab.
Slag structure further includes geotextiles 4, and rubble spats 2 is set in geotextiles 4.
It is equipped with weeper drain 5 between rubble slope protection 6 and armoured concrete slab 3, carries out draining.
Weeper drain 5 protrudes into rubble slope protection 6, and 5 outsourcing geotextiles 4 of weeper drain.
Slag structure further includes set on 5 outer end of weeper drain for fixing the steel wire 7 of weeper drain 5 Yu geotextiles 4, if
In 5 inner end of weeper drain for wrapping up the sand 8 of weeper drain 5.
Slag method of the present invention the following steps are included:
1. a pair downstream river course original ground 1 is simply cleared up.Weeds and the Dangerous Rock Body etc. for removing slope surface, remove the covering of bottom surface
Layer.
2. carrying out slag to the open riverbed in downstream under the premise of not influencing safety.According to the physico mechanical characteristic of rock ballast
Select the slope ratio of slag, generally 1:1.5 ~ 1:3.
The outer surface of slag is placed under repair smooth.
For being located at level of tail water position below, one layer of geotextiles 4 are first laid with, then using in rock ballast in geotextiles 4
Rubble of the partial size greater than Φ fills to form rubble spats 2.For being located at the position of the level of tail water or more, remaining in rock ballast is utilized
Rubble fills to form rubble slope protection 6.Rubble spats 2 should meet the requirement of anti-impact, should fill closely knit, and exposed face need to be repaired flat
It is whole, keep the gradient straight.
The geotextiles 4 of 2 Suo Ya of rubble spats should go deep into certain depth in armoured concrete slab 3, be advisable with being no less than 1m.
3. the position more than the level of tail water is laid with armoured concrete slab 3 on 6 surface of rubble slope protection.Armoured concrete slab 3
Go deep into 1 ~ 2m in rubble spats 2.Weeper drain 5 is set between rubble slope protection 6 and armoured concrete slab 3.Outside weeper drain 5
Packet sets geotextiles 4, and wherein weeper drain 5 protrudes into rubble slope protection 6.
In 5 outer end of weeper drain 7 binding and fixing weeper drain 5 of steel wire and geotextiles 4,5 inner end of weeper drain sand 8
Package.
The embodiment of the present invention is described with above attached drawing, but the invention is not limited to above-mentioned specific
Embodiment, the above mentioned embodiment is only schematical, rather than limitation, those skilled in the art
