Abstract

A bamboo row for extinguishing wave is characterized in that a plurality of bamboo rough heads and thin heads are staggered, a bamboo row single body is formed by mutually binding cross beams of large stiffness, a plurality of bamboo row single bodies are paprallelly connected to form a bamboo row tape along the length direction of the bamboo. When arranged on the waterborne, the length direction of the bamboo is perpendicular to the wave direction, and the bamboo row tape is positioned under the water through an anchorage cable.

Description

A kind of wave bamboo raft that disappears

Technical field

The utility model relates to the unrestrained utensil that disappears that uses when lake ecological is repaired carrying out, particularly a kind of wave bamboo raft that disappears.

Background technology

Comparatively serious eutrophication phenomenon has appearred in the most of lakes of China, especially the lake eutrophication of middle and lower reach of Yangtze River area serious threat continuous development of society economy, government drops into the control that substantial contribution is used for eutrophication, carried out the control that external source is polluted, but because the eutrophic lake majority that China occurs is a shallow lake, be subjected to wind wave action comparatively strong simultaneously, not only the lake aquatic plant is produced physical damnification, also easily cause bed mud to take place to suspend again, reduce water transparency, increase the water pollutant load, so the lake eutrophication regulation effect is not obvious, it is bigger that lake aquatic vegetation recovers difficulty.Therefore reduce lake stormy waves intensity and just become the precondition that lake ecological recovers.So far, the unrestrained measure of taking both at home and abroad to disappear is mainly builds a dam, and this obviously is against in the lake protection, therefore must develop the unrestrained measure that disappears that is with Chinese characteristics.Construction such as prior art CN02110776.9 and running cost are higher, and some can not utilize in the lake, particularly to the zone of some waves that need disappear temporarily, and inconvenience especially.

Summary of the invention

The purpose of this utility model is at above deficiency, and a kind of wave that disappears that provides is used bamboo raft, utilizes buoyancy and the gravity of self, and by the relative motion of mao bamboon in water and the bamboo raft, rubbing of generation examined and the corrugated breakage, and the wave on surface, lake is eliminated.。

The purpose of this utility model is achieved in that a kind of wave bamboo raft that disappears, it is characterized in that many mao bamboons are tied up between mutually and constitute the bamboo raft monomer, again a plurality of bamboo raft monomers are become the bamboo raft band along the length direction connect in series of mao bamboon, when being arranged at the water surface, the length direction of mao bamboon is vertical with next unrestrained direction, and the bamboo raft band is positioned the bottom with anchor cable.Many thick heads of mao bamboon and thin head preferably are staggered.The bamboo raft monomer can be long 5 meters by the 90-100 root, and average diameter is that the mao bamboon of 8.5-9cm is tied up formation by the big crossbeam of rigidity between mutually.

Advantage of the present utility model and effect: utilize the buoyancy of gravity, inertia and the water body of bamboo raft self, cause and water body between relative motion, impel wave breaking, reach and eliminate the wave purpose; Easy construction, low price is removed easily, and China's bamboo resource is abundant, draws materials conveniently.Be applicable to lake, reservoir, the reduction of embankment wave.

Description of drawings

Fig. 1 is the utility model overall construction drawing.

The specific embodiment

Referring to Fig. 1, can the 90-100 root is long 5 meters, average diameter be that 8.5-9cm, thick head and thin staggered mao bamboon are tied up by the big crossbeam 5 of rigidity between mutually and constitute about 10 * 5 meters bamboo raft monomers 1, again a plurality of bamboo raft monomers are become the bamboo raft band along the length direction of mao bamboon with No. 8 galvanized wire connect in series, the prolongation of bamboo raft band is with the disappear regional extent size variation of wave of need.Wherein can be with the big mao bamboon of several diameter 12-14cm hardness, big distance between girders 0.6-0.7m along the crossbeam 2 of the length direction of bamboo raft.All fasten footpath 22mm nylon anchor line 3 always tying up a little of four jiaos of mao bamboons of bamboo raft and beam with the cross method.Anchor can be 1m * 1m * 1m reinforced concrete block or for squeezing into 25cm * 25cm * 5m concrete pile 4 of bed mud 0.5m-0.8m, a pre-buried diameter 1cm reinforcing bar U detains when the casting reinforced concrete block.According to required unrestrained water depth and the position of disappearing, anchor and anchor line connected with U type ring and triangle guard circle be thrown in the water, then anchor line and bamboo raft are coupled together, form the bamboo raft band.The length direction of mao bamboon with come unrestrained direction 6 vertical.

Claims

1, a kind of wave bamboo raft that disappears, it is characterized in that many mao bamboons are tied up between mutually and constitute the bamboo raft monomer, more a plurality of bamboo raft monomers are become the bamboo raft band along the length direction connect in series of mao bamboon, when being arranged at the water surface, the length direction of mao bamboon is vertical with next unrestrained direction, and the bamboo raft band is positioned the bottom with anchor cable.

2, the wave that disappears according to claim 1 is used bamboo raft, it is characterized in that thick head of many mao bamboons and thin head are staggered.

3, the wave that disappears according to claim 1 and 2 use bamboo raft, it is characterized in that the bamboo raft monomer is long 5 meters by the 90-100 root, average diameter be the mao bamboon of 8.5-9cm by the big crossbeam of rigidity, tie up formation between mutual.
