Most preferred embodiment of the present invention

With reference to the accompanying drawings, with way of example preferred embodiment of the present invention is described.

In the embodiment of the invention that Fig. 1 to Fig. 5 shows, the present invention is applied to form on the concrete block of the one-tenth ranks of filling sand wall, this filling sand wall is used to form the square face in the pond in water pump type dam, Fig. 1 forms the vertically three-dimensional view of the wall that bankets on surface of pond in the water pump type dam, this dam pond is piled up with the concrete block of the one-tenth ranks of first embodiment of the invention and constituted; Fig. 2 is a sectional view of the concrete block of these one-tenth ranks; Fig. 3 carries out diagram to the production stage of said soil block; Fig. 4 be show the carbon fiber thigh adhere in detail water-soluble with on the view of situation; Fig. 5 is the explanation to the effect of carbon fiber wire.

The concrete block 10A of these one-tenth ranks has the structure shown in Fig. 1 and 2, promptly by several thousand to several ten thousand superfine (for example, diameter is several microns to tens microns) flexible carbon fiber wire 15 is bundled into carbon fiber thigh thread 14, within a predetermined distance 14 heeling-ins of carbon fiber thigh thread on the surface of the flat rectangular type block 12 that the concrete by compactness forms to form an integral body.Though carbon fiber thigh thread 14 is by on the concrete block of heeling-in all one-tenth ranks in Fig. 1, but in the accompanying drawings, 14 of fiber strand threads only are illustrated as to become on the concrete block 10A of ranks in a part, and the fiber strand thread 14 in other soil block 10A has then omitted in the drawings.

In order to produce this soil block 10A, at first, shown in Fig. 3 (a), concrete is placed in the type frame 16 and reaches preset thickness.Then, as shown in Figure 4, with the end clips of carbon fiber thigh thread 14 be banded can be water-soluble mode in 17 and 17, the thigh thread non-individual body W that strand thread 14 is arranged within a predetermined distance continuously form an integral body.Then, shown in Fig. 3 (b), many gang thread non-individual body W with equidistant with the carbon fiber thigh thread of erectting 14 and be placed on downside can water-solublely be with 17 and be maintained in the type frame 16, and then put into the concrete of compactness.When concrete becomes when solid-state, be with 17 to be dissolved in fully in the concrete and to have disappeared, and carbon fiber thigh thread 14 is just formed on block 12 surfaces by heeling-in equidistantly, thus, produced as among Fig. 1 and 2 with a concrete block that becomes ranks of label 10A representative.

Secondly, the concrete block 10A that uses into ranks as a wall that bankets, is illustrated with the situation of the perpendicular that forms pumping type Tu Qu pond.

So that carbon fiber thigh thread 14 modes towards the pond are piled up concrete block 10A thereon along the outside of spine 30.Therefore, as shown in Figure 5, carbon fiber thigh thread 14 extends approximately perpendicular to concret block 12, at its end then owing to the weight of itself becomes hang.In atmosphere, carbon fiber wire 15 is keeping the bunchy state to a certain extent, but in water, and carbon fiber wire 15 disperses between mutually between every and is fusiform deployed condition, and swings pasture and water or the algae along with current or fluctuation resemble.Reason thus, consider carbon fiber often the positively charged microorganism then tend to electronegative, so always the trend that demonstrates of the carbon fiber wire below horizontal plane 15 is that the microorganism that lives in the water is deposited thereon.And because carbon fiber wire 15 scatter in water and swings, they have many chances to contact with microorganism, so they can have microbe deposition.Therefore, thus carbon fiber wire 15 has machine biomembrane deposition and water is purified.When the water plant seed that swims in water is deposited on the carbon fiber wire 15, just promoted the aquatic plants growth that germinates, the breeding by water plant spreads and demonstrates green state.

The horizontal plane on the surface, pond in pumping formula dam, it highly has the great changes of several meters difference, but the carbon fiber wire 15 that is positioned near the horizontal plane place always is under the environment of the supply that can obtain water, so the microorganism in air or in the water is deposited on the carbon fiber wire easily.Therefore, when the seed of the water plant that floats over horizontal plane was deposited on the carbon fiber wire and germinates, they just were used as nutrients and can tachyauxesis to the corpse of microorganism, thereby the dark green state of plant growing is provided.

Fig. 6 and Fig. 7 have shown second embodiment of the present invention.Fig. 6 is a sectional view that becomes the concrete block of ranks, Fig. 7 be show amplification around the bottom of carbon fiber thigh thread sectional view.
