Description
Technical field
The utility model belongs to water conservancy construction technical field, and in particular to a kind of dam structure of dam.
Background technology
Dam can be divided into concrete dam and earth and rockfill dam two major classes.Natural conditions of the type of dam according to dam site, Building wood
The Integrated comparatives such as material, construction site, water conservancy diversion, duration, cost are selected.Concrete dam is divided into 3 type of gravity dam, arch dam and buttress dam
Type.
1. gravity dam：Remain stable by the frictional force generated between dam body dead weight and basis to bear the thrust of water.Weight
The advantages of power dam is simple in structure, and construction is easier to, and durability is good, is suitable for carrying out high dam building on batholith, convenient for setting
Discharge structure.But gravity dam volume is big, and cement consumption is more, and the strength of materials fails to make full use of.
2. arch dam：It is for a space shell structure, domed in plane, it is convex to upstream, the effect using arch will be born
Horizontal load becomes axial compressive force and reaches two sides basement rock, and two sides skewback supports dam body, keeps dam stabilization.Arch dam has higher
Overload capacity.Arch dam is more demanding to ground and two sides rock, and also heavy force dam difficulty is big in construction.In two sides, batholith is hard complete
Whole Narrow Valleys dam site, particularly suitable for building arch dam.Generally the ratio of dam base thickness degree T and maximum height of dam H（T/H）It is less than
0.1 referred to as thin arch dam；It is known as arch dam between 0.1~0.3；It is known as gravity-arch dam between 0.4~0.6.If T/H values
When bigger, the effect of arch very little is bordering on gravity dam.
3. buttress dam：It is made of inclined capping and buttress.Buttress supports capping, and water pressure is transmitted to buttress by capping,
Ground is transmitted to by buttress again.Buttress dam is one of most economical reliable dam type, compared with gravity dam have small, low cost,
The advantages that ability of adaptation ground is stronger.By capping form, buttress dam can be divided mainly into 3 kinds：Capping is flat referred to as flat
Plate dam；Capping is the referred to as multiple-arch dam of arch；Capping is thickeied the referred to as round-head buttress dam formed by buttress upstream end.Buttress dam is generally
Concrete or reinforced concrete structure.Compare with gravity dam, buttress dam has following features：Upstream capping often make it is skewed,
Water can help to stablize dam body again on capping；Buttress dam component is thin, uniform internal stress, can give full play to the intensity of material；Branch
The lateral rigidity of pier is smaller, and the operating condition of buttress checks when design should be to lateral earthquake；Buttress dam is to foundation condition
Requirement heavy force height of dam.
Existing concrete dam is required to be redesigned according to actual conditions in actual building construction process.
Utility model content
The utility model is in order to solve the defects of prior art, to provide a kind of suitable for dam site control runoff area
65.2km2, 2480 ten thousand stere of Average Annual Runoff, averagely storage silt is 3.58 ten thousand tons for many years, and Suspended Sediment Discharge is
2.98 ten thousand tons, the dam structure for the dam that Sediment Transport amount is 0.6 ten thousand tons.
The utility model is achieved by the following technical solution：
A kind of dam structure of dam, dam body are trapezium structure, swum over to from dam downstream be followed successively by the areas rock ballast Gai Chong,
Clay bedding area, bedding material, Transition Materials, main enrockment, secondary enrockment and loose stone form, and are additionally provided in the dam body upstream bottom
Special material area；The height in the special material area is 3m, and bedding material is C25 concrete face slabs, thickness 2m；The Transition Materials are
M7.5 mortars, thickness 1.5-2m；Block clitter of the main enrockment by diameter less than 0.8m is built；The secondary enrockment
Built by the block clitter of a diameter of 0.8-1m, the thickness of the loose stone is 0.5-0.8m, the areas rock ballast Gai Chong and
The height of the laying height ＜ level of dead waters in clay bedding area.
The anti-flood wall of " L " shape is additionally provided at the top of dam body.
The diameter that mode is stone of piling up of the main enrockment is swum over to upstream from down and is sequentially increased.
The special material area is asphalt brick.
Compared with prior art, the utility model can be suitable for dam site control runoff area 65.2km2, average diameter for many years
2480 ten thousand stere of flow, averagely storage silt is 3.58 ten thousand tons for many years, and Suspended Sediment Discharge is 2.98 ten thousand tons, Sediment Transport
Amount is the dam structure of 0.6 ten thousand tons of conditions.The utility model is designed reasonably, material layout and proportioning are set all in accordance with process conditions
Meter can be good at the completing to intercept water and control flood of the task.The utility model also has the characteristics that construction is fast, fastness is good, uses
The dam structure of the utility model will not ensure that the safety of dam body there is a situation where infiltration in dam body.
