Abstract
The invention discloses an interlocked wave-resistance protection slope precast block system and a construction method. The interlocked wave-resistance and protection slope precast block system comprises I-shaped precast protection slope blocks I (1) laid on a wave-resistance protection slope (3) with the gradient smaller than 1:2. The interlocked wave-resistance protection slope precast block system is characterized in that each precast protection slope block I (1) comprises flanges (1.1), a web (1.2), a groove section (1.3), flange inclined faces (1.4) and chamfers (1.5), wherein the flanges (1.1) are located at the upper end and the lower end of the precast protection slope block I (1), the web (1.2) is located in the middle of the precast protection slope block I (1), and the flange inclined faces (1.4) are located on transition sections between the flanges (1.1) and the web (1.2). The interlocked wave-resistance protection slope precast block system overcomes the defect that precast blocks are generally poured manually through a die in the prior art, and large gaps are liable to occur between the laid precast blocks. The interlocked wave-resistance protection slope precast block system has the beneficial effects that the small-size blocks are connected in a buckled manner, and other blocks cannot slide when a single block is damaged.

Application example
According to " rolling earth-rock dam design specification " (SL274-2001), mix having outseam
Solidifying soil or armoured concrete slab bank protection, when dam slope gradient Coefficient m=2～5, plate is made at buoyancy
Can press with lower stable plate thickness
In formula: η coefficient, assembled protection slab is taken 1.1；
hPCumulative frequency is the wave height of 1%, m；
LmMean wavelength, m；
B is long to plate along dam slope, m；
ρcThe density of plate, t/m3,
ρwThe density of water, t/m3；
The gradient coefficient on the mono-slope of m, if toe is equal to α, i.e. equal to cot α.
According to modular formula, in same engineering, under identical design conditions, t ∝ b-1/3, i.e.
Concrete revetment block thickness t and slope-protection block along dam slope to the long b of plate1/3It is inversely proportional to, namely slope-protection block
The biggest to the long b of plate along dam slope, thickness t is the least for slope-protection block.
Note: for same engineering, hP、Lm、m、ρc、ρw, η be identical, t ∝ b-1/3。
According to above-mentioned formula, bank protection thickness is bigger by b (along dam slope to plate length) impact；Through surveying
Calculate, use I shape prefabricated section of the present invention, long to plate because increasing along dam slope, reduce along dam
Axis direction width, its thickness can reduce nearly 20% than traditional hexagon prefabricated section, reduce accordingly
Construction investment.
Certain large reservoir earth and rockfill dam runs for many years, and former dry stone pitching structural failure is serious, need to enter
Row consolidation process.By force and it is prone to construction, design in view of concrete precast block bank protection durability
Propose to use the bank protection mode of the chain concrete precast block of I shape, this engineering prefabricated slope-protection block chi
Very little for length L=80cm, width E=30cm, highly D=20cm, edge of a wing length a=16cm, abdomen
Plate length b=32cm, web width f=18cm, edge of a wing surface width c=8cm, chamfering deep
Degree h=1cm, after enforcement, dam facing is smooth attractive in appearance, achieves extraordinary protection effect.
The gradient of groove corresponding at inclined-plane, the edge of a wing 1.4 excavation is less than 1:1；
If taking the hexagon prefabricated section of identical weight, prefabricated section perspective view is (such as figure
7).According to " rolling earth-rock dam design rule " (SL274-2001) appendix A .2.3 concrete
It is the length of side that bank protection thickness equations can be calculated the size of the hexagon prefabricated section meeting condition
R=25cm, thickness J=24cm, and the I shape prefabricated section thickness under equal design conditions only needs
20cm, in the case of slope-protection block weight is identical, meets same anti-impact anti-floating effect, bank protection
Block thickness reduces 20%.Simultaneously compared to hexagon slope-protection block, I shape slope-protection block uses sky
Between be engaged the flexible connection mode of interlocking, enhance the stability in the large of protective slope structure, it is possible to have
The external force such as effect opposing settlement deformation, frost heave, wave cut, earthquake are destroyed.
I shape is added up with hexagonal laying quantity required
| Slope-protection block form | Thickness (cm) | Surface area (m2) | Every 100m2Need slope-protection block quantity (block) |
| I shape | 20 | 1920 | 521 |
| Hexagonal | 24 | 1624 | 616 |
Wherein I shape prefabricated slope-protection block I needs cost about 10,000 yuan altogether, but six traditional limits
Shape slope-protection block needs about 10,000 5 thousand yuan, also demonstrates the economic valency of I shape prefabricated slope-protection block I
Value height, when the most large-area laying, has the prospect of well popularization.
Above-mentioned unspecified part is prior art.
