Description
Technical field
The present invention relates to ground bulkhead tech field more particularly to a kind of step-like ecological slope protection of reservoir area fluctuating zone and in fact
Applying method.
Background technique
With the successful water storage and operation of the key water control projects such as Three Gorges Dam, due to originals such as natural cause or reservoir operations
Cause, reservoir level can fluctuate in the range of more than ten meters even tens meters, form the region that reservoir area is periodically flooded and exposes the surface,
Referred to as reservoir area fluctuating zone.Some gradients are bigger, water flow is relatively more anxious, the serious region of wave cut, the vegetation of falling zone is held
It is subject to destroy, forms bare region, accelerate the deterioration and slope failure of falling zone rock and soil properties.
Traditional river, lake, reservoir etc. are mainly that plain pneumatically placed concrete layer or mortar flag stone etc. are " hard to the control measures of bank slope
Property " project post-evaluation measure, but these measures river basin ecological improvement in have significant limitations.Spray mixes or mortar flag stone side slope
Though having stronger water resistant stream scouring capability, once tiny breakage occurs in surface, surging directly to be contacted with bank soil,
The surge that impact slope surface generates when broken, it is in a saturated state in addition the soil body is by water long period of soaking, cause soil strength compared with
Low, surge can cause soil body particle to move, and gradually to external migration, soil moieties are molten in water body in addition
It solves, will be emptied to form huge " hole " inside long bank slope, and be unfavorable for stability of slope.In addition, plain pneumatically placed concrete layer or slurry
Building slabstone cannot be harmonious with surrounding landscape, does not meet the principle of river basin ecological tourism construction, thus is not suitable for big in reservoir area
Area application.
Recently as the mankind to the pay attention to day by day of ecological environment problem, by being given birth to traditional Riparian Zone bulkhead tech
State transformation has developed ecological treatment of slope measure and the ecological riparian zone constructing technology of " soft ".But for high steep
Or rock slope, plant growth medium is difficult to be attached to slope surface or growth substrate is easy to be taken away by wave cut, and plant is difficult
With growth.The ecological riparian zones constructing technologies such as gabion shore protection, net-bag type earthing shore protection are only applicable to hydrostatic basin bank slope or flow velocity
Bank slope smaller, flow is little.
Summary of the invention
The object of the present invention is to provide a kind of step-like ecological slope protection structures of reservoir area fluctuating zone, it is characterised in that: falling zone
On slope on, be provided with the horizontal platform terrace of several concretings.It is level-one slope between adjacent horizontal platform terrace.
One of concrete prefabricated straining beam of every level-one slope lower end setting.The concrete prefabricated straining beam lower section and horizontal bench
Face contact.The concrete prefabricated straining beam has several anchor holes passed through for anchor pole.By insertion anchor hole and squeeze into sloping inner
Anchor pole so that concrete prefabricated straining beam is fixed.
The top of the concrete prefabricated straining beam is laid with several vegetation form cellular concrete Prefabricated blocks.The vegetation type is more
The concrete prefabricated module in hole is the hollow concrete block of upper end opening.In the cavity of the vegetation form cellular concrete Prefabricated block
After inserting planting matrix and planting resistance to submerged plant, paving fills out one layer of sandstone.
Further, the vertical height difference between adjacent two-stage horizontal bench be 2~3 meters, horizontal platform terrace width be 0.7~
1.0 rice.
Further, the upper surface of the vegetation form cellular concrete Prefabricated block has baffle wall style.The resistance to submerged plant
Selected from Bermuda grass.
Further, the vegetation form cellular concrete Prefabricated block is staggeredly laid with, so that the fissure of displacement between upper and lower two layers.
The present invention also provides a kind of implementation methods of the step-like ecological slope protection structure of reservoir area fluctuating zone, which is characterized in that packet
Include following steps:
It is worth noting that slope vegetation protection technology and project post-evaluation technology are combined by the present invention, the excellent of the two is played
Gesture.On the one hand with the growth of plant, the fine cracks that rigid reinforcement measure occurs can be covered to a certain extent, are prevented by wave
Wave, which washes away, to be emptied to form increasing hole.On the other hand the erosion resistibility that rigid measure has can rely again for vegetation
The matrix of growth provides protection.The present invention not only ensure that the stabilization of falling zone Rock And Soil, but also realize the recovery of falling zone vegetation, reach
To the harmony of mankind's activity and natural environment.
S1: the cleaning of falling zone side slope: the Rock And Soil of reservoir area fluctuating zone side slope surface failure of rock is carried out to cut slope cleaning.
S2: prefabricated several segments beams of concrete.Prefabricated vegetation form cellular concrete Prefabricated block.
S3: a horizontal bench, adjacent level the construction of horizontal bench: are constructed every certain altitude on rock and soil slope
It is ground slope between step.Horizontal bench is to be cast on ground slope to be formed with cement.
S4: the construction of slope concrete anchor pole straining beam: being laid with prefabricated beams of concrete in each horizontal bench, these
Beams of concrete joins end to end, and forms the concrete prefabricated straining beam together in horizontal bench.
By setting anchor pole on the slope, one of horizontal concrete anchor rod straining beam is fixed in every level-one slope lower end.
S5: the construction of concrete prefabricated module on slope: every level-one slope is first laid with one layer of sandstone as bed course.
S6: it since the position of the mixed concrete anchor rod straining beam of slope bottom, is in turn laid with from the bottom up prefabricated
Vegetation form cellular concrete Prefabricated block.
6. a kind of implementation method of the step-like ecological slope protection structure of reservoir area fluctuating zone according to claim 5, special
Sign is: the vegetation form cellular concrete Prefabricated block is in staggered arranged distribution, avoids the formation of vertical straight joint.
Advantage and effect of the invention is:
(1) slope protection slope surface has been laid with prefabricated restoring vegetation concrete module, and block cavity kind is implanted with the water-fast plant dog flooded
Root of the tooth, block cavity can protect plant production matrix during water logging and be not flushed away, and can effectively store moisture content in the precipitation phase
With collection rainfall, guarantees plant growth, reach the ecological protection of slope protection and the aesthetic effect with environmental harmony.
(2) it is distributed between building block using alternating expression, makes building block not and will form vertical straight joint, overall stability can be enhanced；When
When surge impact slope surface, water (flow) direction, which need to be varied multiple times, just may pass through building block, can largely slacken kinetic energy of surging；
(3) because the effect for the graded sand building stones that the stromal surface of planting covers, further decreases kinetic energy of wave,
The scouring force of vegetation growth matrix is accordingly reduced；
(4) baffle wall style being arranged in building block can shorten water flow in the diameter flow path of slope table, further decrease and surge to bank slope
Destructive power.
(5) horizontal bench being arranged is conducive to the needs such as maintenance and pedestrian to slope surface and plant.
(6) slope protection module can be prefabricated, and construction when does not need big machinery, less using material, constructs easier,
Reduce cost.
