Description
Technical field
The utility model relates to that side slope is anti-, draining field, especially a kind of slope drainage structure.
Background technology
Water is the key factor causing slope instability, can cause following adverse effect: the water in the body of (1) slope will cause slope body structure deadweight to increase, and side slope sliding force is corresponding increase also; (2) water in the body of slope can reduce the physical and mechanical property of slope body structure, reduces slope stability; (3) in the body of slope, underground water generation hydrostatic pressure, penetration etc. affects slope stability." control slope first to harness the river ", for slope project, usually top-priority is process for water, namely how to prevent rainwater and domatic water from entering to blend how to reduce the inner groundwater table of slope body.
At present, conventional discharge structure is for arrange catchwater in the domatic upper end of Slope body, and body domatic lower end in slope is provided with gutter, and the slope body between catchwater and gutter is domatic is provided with layer of concrete, and layer of concrete place is provided with multiple slope and shows drain hole.Such structure is due to the setting of top catchwater, and domatic water more than protective range is truncated carrying-off, and can not continue dirtyly affects slope stability again; Due to the setting of domatic closed concrete layer, slope table water (being caused by rainfall etc.) in protective range cannot be infiltrated again; The setting of slope table drain hole, can discharge the underground water of slope surface, make slope surface be in the state of drainage, can not weaken because of underground water; Domatic water in protective range can be drained by body lower end, slope gutter in time.But, this slope drainage structure only shows the process of underground water to domatic water and slope, the underground water darker for the inner buried depth of slope body does not then process, when side slope deep under ground has Upon Slope Stability to play the structural plane of controlling, the stability of side slope will worsen by influence on groundwater, cause damage.
Utility model content
Technical problem to be solved in the utility model is to provide a kind ofly internally can descend water to carry out the slope drainage structure of ejectment to side slope.
The utility model solves the technical scheme that its technical problem adopts: slope drainage structure, comprise slope body, the domatic upper end of body, described slope is provided with catchwater, body domatic lower end in slope is provided with gutter, slope body between catchwater and gutter is domatic is provided with layer of concrete, layer of concrete place is provided with many row slopes table drain hole, also comprise multiple drainage tunnel, first internal drainage hole, it is inner that drainage tunnel is positioned at slope body, and be arranged in order from top to bottom, connected by the first internal drainage hole between adjacent drainage channel hole, the top of each drainage tunnel is provided with a second suitable internal drainage hole, second internal drainage hole becomes the angle outside dip slope relative to suitable drainage tunnel, second internal drainage hole is arranged on drainage tunnel and slope is shown between drain hole.
Further, the two ends outlet of drainage tunnel lays respectively at side slope protection scope with on outer slope.
Further, the cross sectional shape of drainage tunnel is gateway opening type.
The beneficial effects of the utility model are: arrange drainage tunnel in Slope body inside, drainage tunnel is preferably arranged on the place that the inner Upon Slope Stability of side slope plays controlling, the first internal drainage hole is provided with between drainage tunnel, effectively drainage tunnel is blocked with the underground water of body inside, inner slope, and drained by drainage tunnel; The second internal drainage hole is provided with above drainage tunnel; second internal drainage hole is arranged on drainage tunnel and slope is shown between drain hole; underground water between drainage tunnel and protected slope being shown drains into drainage tunnel place; then drained by drainage tunnel; thus make the outside of side slope and the inner state being all in drainage; reduce because the inner underground water of side slope is on the impact of slope body structure physical property, improve the stability of side slope.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Mark in figure: catchwater 1, gutter 2, layer of concrete 3, slope table drain hole 4, internal drainage hole 7, drainage tunnel 5, first internal drainage hole 6, second.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described in further detail.
As shown in Figure 1, slope drainage structure, comprise slope body, the domatic upper end of body, described slope is provided with catchwater 1, body domatic lower end in slope is provided with gutter 2, slope body between catchwater 1 and gutter 2 is domatic is provided with layer of concrete 3, layer of concrete 3 place is provided with many row slopes table drain hole 4, also comprise multiple drainage tunnel 5, first internal drainage hole 6, it is inner that drainage tunnel 5 is positioned at slope body, and be arranged in order from top to bottom, connected by the first internal drainage hole 6 between adjacent drainage channel hole 5, the top of each drainage tunnel 5 is provided with a second suitable internal drainage hole 7, second internal drainage hole 7 is relative to the angle outside suitable drainage tunnel 5 one-tenth dip slope, second internal drainage hole 7 is arranged on drainage tunnel 5 and slope is shown between drain hole 4.
Concrete, body domatic upper end in slope is provided with catchwater 1, body domatic lower end in slope is provided with gutter 2, slope surface between catchwater 1 and gutter 2 is provided with layer of concrete 3, layer of concrete 3 is provided with many row slopes table drain hole 4, domatic water beyond side slope protection scope can be blocked by catchwater 1, and gutter 2 can by the orderly ejectment of domatic water within the scope of side slope protection; Due to the setting of domatic closed concrete layer 3, slope table drain hole 4, within the scope of side slope protection, domatic water cannot infiltrate, and the underground water of exterior portion position, slope also will be discharged, and exterior portion position, slope rock mass will be in drainage state all the time.In body inside, slope, drainage tunnel 5 is set, drainage tunnel 5 is preferably arranged on the place (finding by reconnoitring) that the inner Upon Slope Stability of side slope plays controlling, the first internal drainage hole 6 is provided with between drainage tunnel 5, effectively drainage tunnel 5 is blocked with the underground water of body inside, inner slope, and drained by drainage tunnel 5; The top of each drainage tunnel 5 is provided with a second suitable internal drainage hole 7; second internal drainage hole 7 is the angle outside dip slope relative to suitable drainage tunnel 5; second internal drainage hole 7 is arranged on drainage tunnel 5 and slope is shown between drain hole 4; underflow between drainage tunnel 5 and protected slope being shown is to drainage tunnel 5 place; then discharged by drainage tunnel 5; thus make the outside of side slope and inside all keep drainage state; reduce because the inner low water of side slope is on the impact of side slope physical property, improve the stability of side slope.
Particularly, the two ends outlet of drainage tunnel 5 is positioned at side slope protection scope with on outer slope, can substantially by inner underground water ejectment, because drainage tunnel 5 outlet is positioned at beyond side slope protection, drainage tunnel 5 construct with protective range within layer of concrete 3 and slope show drain hole 4 and construct and do not interfere with each other, difficulty of construction is less.Drainage tunnel 5 cross sectional shape adopts gateway opening type, and crown is gateway opening type, and structure is more stable.
