Description
Technical field
The utility model belongs to water conservancy and hydropower technology, and in particular to a kind of rock.
Background technique
Rock-fill dams are applied more and more widely in hydraulic and hydroelectric engineering construction, but some engineerings, due to natural geology item
Part influence, local material is based on mud stone, if mud stone is given up at this time, by force find or the higher dam material of outsourcing intensity,
The increase of project amount and investment can be directly resulted in, and will increase the scale of Dumping Sites, environment is adversely affected.
Patent CN201420137258.1 discloses a kind of rock using mud stone dam material, belongs to power station base
Plinth field of engineering technology, upstream side are followed successively by transition zone, bed course and upstream slope-protection from inside to outside, the upstream apron layer and upper
Trip rock ballast loading layer is located at upstream side lower section, and the special bed course is located at bed course end, dam body rockfill area including drain rockfill area,
Mud stone rockfill area and hard rock rockfill area, the draining rockfill area are located under transition zone on one side, horizontal on one side to distinguish mud stone enrockment
At upper and lower two parts, lower part mud stone rockfill area is located on the dam foundation, and upper part mud stone rockfill area is located at the level of tail water or more
Dry section is equipped with loaded filter in the top and bottom of upper part mud stone rockfill area and downstream side.Mud stone is arranged in program proposition
It in dam body dry section, can fully be built a dam using mud stone, material used in mud stone rockfill area is mud stone entirely, it is well known that mud
Rock meets water easy disintegrating, softens and intensity is caused to decline and collapse, and especially mud stone rockfill area is close to the region of draining rockfill area, more
Be easy disintegration, cause in fact the independent arrangement of this mud stone be difficult to apply in practical projects.
How to efficiently use mud stone to build a dam and overcome its disadvantage, it is urgently to be solved to become hydraulic and hydroelectric engineering technical staff
Problem.
Utility model content
In view of the above-mentioned problems, the utility model is intended to provide, a kind of stability is good, highly-safe is built a dam using mud stone
Rock.
The technical solution that the utility model solves the problems, such as is: a kind of rock, be included in upstream side from inside to outside according to
Transition zone, bed course and the panel of secondary setting are equipped with main rockfill area in the downstream side of transition zone, and the downstream side against main rockfill area is set
There is secondary rockfill area, is equipped with the area Zeng Mo at the top of main rockfill area and time rockfill area；
The main rockfill area is mainly built up by hard rock, and the filler of secondary rockfill area is the blend composition of rock and mud stone；
The mud stone slag area after the downstream side of the area Zeng Mo and time rockfill area is equipped with dam, mud stone slag area downstream side is equipped with behind dam
Downstream protection slope；
Mud stone slag between transition zone downstream side and main rockfill area upstream side and behind main rockfill area, secondary rockfill area, dam
The chimney drainage area being connected to is equipped between area bottom and ground；
Mud stone slag area bottom is equipped with loaded filter behind main rockfill area, secondary rockfill area and dam.
Ground is passed to by main rockfill area after passing through bed course and transition zone due to most water ballast(ing)s in the main rockfill area of upstream
In base, it plays a supportive role to panel, it is desirable that it has enough compactness and necessary deformation modulus, therefore is preferably filled out using hard rock
It builds.
Downstream time rockfill area, it is smaller due to being influenced by water ballast(ing) far from panel, mud stone material can be made full use of, mud stone can be adopted
With strong, weak weathered mudstone, mud stone mixed ratio can be used 70%~100%.
Since different materials has been filled in primary and secondary rockfill area, it is also contemplated that the sedimentation in mud stone later period, uneven to reduce dam body
Even sedimentation improves anti-seismic performance, and the area Zeng Mo is arranged on primary and secondary rockfill area, and the new of weak weathering and gentle breeze can be used in the area Zeng Mo
Fresh hard rock.
Mud stone slag area behind dam, maximizing dissolve mud stone and protect the secondary heap in downstream at the same time as dam adverse grade ballast
Stone area stablizes safety.
Mud stone reclamation district is protected by chimney drainage area and loaded filter, significantly reduce dam body seepage failure can
It can, it is ensured that the security reliability of dam body.
Further, the main rockfill area is built up by the blend composition of hard rock and mud stone, mud stone ratio shared by main rockfill area
Example is less than mud stone ratio shared by secondary rockfill area.It, can be in main rockfill area hard rock when such case is suitable for that mud stone need to be dissolved
Appropriate blending mud stone, mud stone must be using weak weathering and the fresh mud stone of gentle breeze, and mixing proportion is no more than 30%.
Preferably, the top at the top and the area Zeng Mo of the chimney drainage area is contour.
Further, in panel upstream side, be successively arranged upstream clay bedding layer and mud from inside to outside against panel lower section
Rock waste loading layer.
Further, toe board is equipped at upstream face slope foot, on the ground positioned at panel periphery, in upstream face slope foot and toe
Plate junction is equipped with special bed course.Though special bed course described here has " special " two word, this noun belongs to this field
Technical term, there is no smudgy.
The remarkable result of the utility model is:
1. by the subregion arrangement of dam body and the blending of mud stone and hard rock, and effective filter material and draining knot is arranged
Structure is built a dam using mud stone to greatest extent while guaranteeing dam stability, overcome mud stone meet water easy disintegrating, softening and
The problem of causing intensity to decline and collapse, dam structure are stablized, such that mud stone is built a dam in practical engineering applications, subtract
Lack waste, reduces the destruction to environment.
2. excavated material and local materials can be efficiently used, solves engineering cubic metre of earth and stone equilibrium problem, reduce construction investment
And cost.
