Description
Technical field
The present invention relates to one kind to block water dam, and in particular to drag-line is arranged before dam to bear pulling force to prevent dam in one kind
The dam overturned backward under the pressure effect of water, belongs to hydraulic engineering and technical field of civil engineering.
Background technique
World's dam develops towards higher thinner direction at present：There are 185 meters of height of dam of concrete gravity dam Three Gorges big
Dam, has 304 meters of height of dam of earth and rockfill dam to exert Lek dam at the arched concrete dam Jinping I dam for having 305 meters of height of dam.It may be said that highest
Dam also just just to have reached 300 meter levels other, and various dam types have the shortcomings that it respectively, as concrete gravity dam was being constructed
The bad control of temperature, dam body materials intensity cannot give full play in journey；Arched concrete dam requires high, formwork complexity to landform
Deng；Earth and rockfill dam anti-flood capacity is poor, dam embankment material is too many etc..
After over half a century since cable-stayed bridge in 1956 comes out, technology for cable-stayed bridges is developed on an unprecedented scale.The world at present
On the cable-stayed bridge of largest span that builds up be Russian island bridge, main span diameter is 1104 meters, is completed in July, 2012.Domestic
Changjiang River Main Bridge revive across 1088 meters.
Previous dam is all to take facility behind dam to prevent it from toppling backward, is prevented without building facility before dam
Only dam topples backward.The span of bridge is substantially improved in the appearance of cable-stayed bridge, and there are many cable-stayed bridge advantage, and previous dam does not all have
Have and the advantages of cable-stayed bridge is applied in dam.
Summary of the invention
The technical problem to be solved by the present invention is to：Technology for cable-stayed bridges in science of bridge building is applied in dam construction technique
To provide the dam of a kind of high dam body and thin dam body.
The technical solution that the present invention solves the problems, such as is：A kind of dam, including column, water retaining facing, ground, anchor pole, drag-line,
Seepage proof curtain.
Further, column is equally spaced in certain distance along axis of dam direction.
Further, water retaining facing is set between each adjacent two column, which is an entirety, face from top to bottom
The junction of plate and column is equipped with sealing.
Further, ground is set in each column corresponding dam front direction, is squeezed into the surrounding rock body of the ground certain
Ground is firmly fixed in surrounding rock body by the anchor pole of quantity.
Further, it is connected between column and ground with several drag-lines, when dam water storage, drag-line bears pulling force, by power
Pass to ground.
The beneficial effects of the invention are as follows：It saves dam concrete dosage, shorten construction period, each monolith independent action, when
One monolith do not interfered with when being destroyed other monoliths normally act on, before dam be arranged drag-line transmit pulling force material can be made strong
Degree gives full play to, is adaptable to landform geological conditions, the uplift pressure at dam bottom is small, formwork is simple, temperature stress is small, stream side downstream
To for Cable-Stayed Bridge Structure model, belong to statically indeterminate structure, overload capacity is strong, be not afraid of the unrestrained top of flood, dam can build it is higher more
It is thin.
Detailed description of the invention
Fig. 1 is cross sectional view of the invention.
Fig. 2 is plan view of the invention.
In figure：1, drag-line；2, water retaining facing；3, column；4, ground；5, anchor pole；6, seepage proof curtain.
Specific embodiment
The present invention will be further explained below with reference to the attached drawings.
As depicted in figs. 1 and 2, the present invention includes drag-line 1, and the direction of drag-line 1 is parallel with river direction, and one end is connected to
On ground 4, the other end is connected on column 3.Water retaining facing 2 is overlapped between two neighboring column 3.In the surrounding rock body of ground 4
Several anchor poles 5 are squeezed into, anchor pole head will expose certain length, be used to connect with ground.
Water retaining facing 2 can be made by the high-strength waterproof material such as steel construction, armored concrete, bituminous concrete.
The water retaining facing 2 and 3 junction of column are equipped with sealing.Dam can be reduced to multispan letter in axis of dam direction
Branch beam model carries out mechanical analysis, and each column 3 can be reduced to Flexural cantilever model and carry out mechanical analysis, and Parallel to the flow direction is by drag-line
1, the entirety that column 3 and ground 4 connect into can be reduced to " cable-stayed bridge " model and carry out mechanical analysis.
The cross section of the column 3 is T-shape, wants larger with the contact area of 2 junction of water retaining facing, in order to make two
The overlap joint of person is reliable, concentrates convenient for arranging sealing facility and preventing stress；In order to which the traffic of dam crest and equipment are installed, " T "
The cross section of type column 3 should have certain length in Parallel to the flow direction.
The cross section of the ground 4 is T-shape, and the top area connecting with drag-line 1 wants larger, is exactly in order to sufficiently sharp
The stabilization of ground 4 is maintained with the weight of silt in reservoir and water.
According to the topographic and geologic condition of Practical Project, the setting pattern of drag-line 1 mainly has fan type, harp type and radial pattern three
Kind.
According to the concrete condition of Practical Project, the pattern that water retaining facing 2 can be taken has：Flat, arch and round-head buttress dam formula.
The dam body bottom is equipped with seepage proof curtain 6.
