Description
Technical field
The utility model belongs to hydraulic engineering field, and in particular to a kind of concrete prefabricated block, the utility model also relate to
And a kind of assembling interlock type protection-apron for being mainly used for fine soil plain area stream bed or field ditch foot guard.
Background technology
Washed away for a long time in flow, artificial dredging the effects that under, stream bed, soil property field ditch continue incision, are worn under serious threat
The normal operation of the engineerings such as shallow embedding pipeline, optical cable.To avoid the underground installations such as pipeline, optical cable buried depth deficiency or local exposure, palpus
Lay stream bed, field ditch bottom protection against erosion, incision engineering.
At present, stream bed, field ditch foot guard engineering in general are using underground anti-scour wall, flow surface, mortar laid stone lining, jackstone
Protection-apron, gabion etc., using very extensive in terms of the line projects such as railway, highway, oil-gas pipeline administer the damaged or destroyed by flood of stream road.
It facts have proved：Underground anti-scour wall is applied widely, and protection effect is good, and stronger stream road Flood disaster is acted on for punching
Regulation effect is especially pronounced, but project cost is higher, and Construction on Environment is affected, especially fine earth Plain Bao Shui areas, base
It is larger to cheat excavation, Yield rainfall relation, based process difficulty.Flow surface, mortar laid stone lining are suitable for basicly stable stream bed, field ditch
Foot guard, although project cost is relatively low, construction is simple, easy-maintaining, resistance to deformation, frost heaving resistant poor performance, it is fragile, it is whole
Protection effect is poor.Jackstone protection-apron is suitable for relatively stable stream bed, field ditch, resistance to deformation, frost heaving resistant performance and energy dissipating effect
Fruit is good, and project cost is relatively low, but may increase difficulty of construction because block stone grain diameter is larger, and part is fragile.Gabion is applicable in
In washing away the stream bed relatively strong, basis is weak, field ditch foot guard, resistance to deformation, frost heaving resistant performance and effect of energy dissipation are good, and
Construction is simple, but project cost is higher, and part is fragile, and runtime maintenance cost is higher.
Fine soil plain area landform is gentle, and damaged or destroyed by flood development in stream road is faint, but groundwater level depth is shallower, stream bed, field ditch
Bottom rock-soil body mostly in saturation state, easily liquefy by vibration.Stream bed, the dredging of field ditch part and its slow incision may
Lead to the underground shallow burieds engineering such as pipeline, optical cable buried depth deficiency, even exposure.For above-mentioned rough sledding, using underground anti-scour wall,
Its foundation trench excavates, Yield rainfall relation difficulty is larger, and abundant underground water seriously affects construction quality；Using flow surface, mortar laid stone lining,
Because of stream bed, field ditch base foundation is weak, ground body water content is high, leads to constructional difficulties and fragile；Using jackstone protection-apron with
Gabion, volume is larger, blocks stream road and field ditch, reduces discharge section area, influences flood passage and overcurrent.Therefore, it is necessary to
A kind of simple and practical stream bed of utility model design or field ditch foot guard engineering and construction method.

Further, concrete prefabricated block is formed by once-pouring of concrete, and in square, length of side A is generally 30
~100cm, thickness H are generally 5~10cm.
Further, stiffener is completed by a reinforcement fabrication, is closed around forming one with bar connecting hole in one
The entirety of conjunction.
The technical solution that the utility model is taken by above-mentioned second technical problem of solution is as follows：A kind of assembling interlock type shield
It is smooth；It is characterized in that：By be laid on stream bed or field ditch bottom and large number of concrete prefabricated block upper and lower, left and right
It is mutually permanently connected and forms.
Further, connection reinforcing bar passes through the bar connecting hole of adjacent two block concretes prefabricated block, mixed by adjacent two pieces
Solidifying soil prefabricated block is fixedly connected.
Compared with prior art, the beneficial effects of the utility model are：It is surrounded by concrete precast block body along block
Stiffener, not only increases the intensity of block, and constitutes continuous bar connecting hole；Concrete prefabricated block can shift to an earlier date
It is prefabricated, the convenient, short time limit of combination installation interlock type protection-apron construction；Interlock type protection-apron is assembled by large number of concrete precast block
Composite assembly is interconnected to constitute, and flexible characteristic is notable on the whole, has stronger antiscour, resistance to deformation, frost heaving resistant thaw collapse
Can, the whole succinct, low engineering cost of protection-apron, protection effect are good, to stream road flood discharge capacity, surface disturbance, vegetation deterioration etc.
The influence of natural geological environment is slight, adapts to the various rivers, raceway groove, field ditch foot guard of fine soil plain area distribution, especially often
Year property flowing water or underground water exposure area's shallow embedding engineering protection.
