The concrete block offered by the utility model has the efficacies of preventing the scouring of river revetment, strengthening beds, protecting coasts, breakwater for harbours, etc. The utility model has the advantages of simple structure, convenient construction, high stability, high void ratio (about 60%) and practicability.

Description

The seashore river construction is protected the positive hexagon hollow triangle block of base with the wave absorption energy dissipating

The utility model relates to a kind of seashore river construction wave absorption, the base concrete piece is protected in energy dissipating.

At present, China's seashore river construction wave absorption energy dissipating protects that base usually adopts is to play timber, heap sand hill or directly cast method such as concrete block on basal plane, and existing these methods are in its actual effect and be subjected to certain limitation on service time.

The purpose of this utility model is to provide a kind of soundness good; void content is big; easy construction, value-for-money, and can reach and prevent that energy dissipating, wave absorption that the rivers and creeks shore protection is washed away, consolidates the purpose of riverbed and protection seashore, bay, mole from protecting base with positive hexagon hollow tripod concrete block.

For achieving the above object, the utility model is by the pin (1) of three five prisms, and links three five trunks (2) of above-mentioned each pin and be integral, and forms the big space of a hexagonal cylindricality in the middle of whole and the concrete block (referring to Fig. 1 to Fig. 4) that constitutes.Just edges and corners can reserved steel bar when casting outward for each pin of this concrete block.When reality was used, above-mentioned concrete block is the monomer of structure as a whole, adopted suitable arrangement, amassed frame modes such as folded according to concrete mode of occupation, protected the purpose of base to reach the wave absorption energy dissipating.

Advantage of the present utility model is: one, because each major part of this concrete block all is formed with the event of corner angle, the mutual friction of each major part heightens, and when construction, cast because of showing field boundary, but reserved steel bar in each pin, be integral (as Figure 11) and per three concrete blocks are connected to each other, and make all concrete block integral body that high soundness be arranged, two, the concrete block surface roughness is big, void content is big (more than 60%) also, and therefore, wave dissipation effect of the present utility model is quite big, void content represents that greatly promptly the concrete block that is used relatively reduces, and is favourable to the reduction of engineering cost.

Accompanying drawing 19 is for after the utility model concrete block is positioned at the gravel riverbed regular period, between its pin and the situation schematic diagram of space gravel buildup.

Introduce several embodiment of the present utility model below in conjunction with accompanying drawing:

Embodiment one: the long-pending folded method of the random throwing of the mode of occupation first of base concrete piece is protected in the wave absorption energy dissipating, is about to long-pending arbitrarily brokenly the folding to bring into play of most concrete blocks and eliminates wave, consolidates effects such as basis;

Embodiment two: the wave absorption energy dissipating protect the base concrete piece mode of occupation its two are the long-pending folded methods of rule, be about to the assortment regularly of most concrete blocks and use.From economic point of view, the size of visual flow velocity wave power, protected bunding important etc. and decision are selected for use as the thin assortment of Fig. 5, Fig. 6 or are selected close assortment as Fig. 7 for use.Fig. 8, Fig. 9 are one of the regularly arranged example of two layers of the utility model concrete blocks, can add the concrete block layer of folded same soundness above it more arbitrarily, and purposes is very wide.

When generally settling the obstruction as concrete block one class in marine or korneforos; (arrow among Figure 16 is represented current or do not had the impact direction of wave) its front will be scraped out pothole (shown in dotted line) by middle brush as shown in figure 16, and this is the common common wandering first step of concrete block; yet; wash away when carrying out; the concrete block of the utility model then as shown in figure 17; it inserts the direction malleable not that makes concrete block in this pothole on the contrary in the face of lower end of current one leg; be difficult for wandering simultaneously; increase soundness; being in its next-door neighbour's trunk part of this state again connects airtight the lining of formation tabular and big lining efficient is arranged with seabed or riverbed gradually; for the seabed; the protection in riverbed is quite effective, and simultaneously the energy of current can its coarse and corner angle be subdued in the space of end and centre on concrete block three both feet.In addition when placing the big rivers and creeks of riverbed particle, because the space between concrete block, will make gravel buildup that the upstream sweeps away therebetween, as the situation of Figure 18 and Figure 19.

For reaching the effect of above-mentioned mode of occupation, this type of concrete block just satisfies following designing requirement and does following consideration:

(1) concrete block must not be subjected to current or wave impact and is shifted or wandering, promptly must have good soundness, especially, not only must make each individuality have good soundness, while, also Ying Yu was when majority amasss folded the use, each concrete block can be eaten mutually close and increase stability and unlikely scattering, as with Fig. 5, when mode shown in Figure 6 is used, the soundness of special requirement concrete block individuality, and with the use situation of Fig. 8, double-deck regularly arranged method shown in Figure 9, its soundness depends on then that eating mutually of concrete block closed and mutual friction etc.

(2) if when being main with effect such as reduce water velocity and prevent that the riverbed from being washed away, the surface roughness and the riverbed lining efficient that are concrete block have suitable effectiveness, for effect of energy dissipation, the void content that concrete block surface roughness and concrete block pile up is big, all belongs to effectively and water flow dynamic energy is absorbed in the space.

(3) be used in the rivers and creeks and protect base, during groynes, because the rivers and creeks, upstream mostly has inconvenient traffic, large tonnage crane often can't enter the building site, so texturally should be suitable for showing field boundary and cast and be advisable, so not only can save the inconvenience that expenses of labour more can overcome landform.

(4) be used in the rivers and creeks, during groynes,, then still can mend to pile during as arrangements of Fig. 7 in the future and increase, reach energy dissipating, the effect of carrying water because washing away of current cause concrete block to sink gradually.

(5) must make the size shape of concrete block each several part balanced mutually, can dispose the worry of also not having breakage arbitrarily during construction.Simultaneously, the model that must make concrete block is simply in the hope of easy constructions such as the casting of concrete and the demouldings.

The positive hexagon hollow tripod concrete block of base is protected in wave absorption provided by the utility model, energy dissipating, can satisfy above-mentioned terms and conditions and requirement.
