Description

Doubie-column type wave eliminating block

The utility model belongs to the basic building block class in harbour or the waterway construction engineering, and it is specifically related to a kind of structure of novel doubie-column type wave eliminating block.

Protective such as mole, shore protection engineering occupies an important position in port construction, also occupies very high ratio in engineering construction cost.Therefore all be very important as the structure of the wave eliminating block of basic building block, hydraulic characteristic(s), the stability piled up, its crucial content is the unrestrained performance that disappears in its hydraulic characteristic(s).Kind surplus the wave breaker block that is used for the vertical type bulkhead wall at present has ten, the common WAROK that Japan is arranged and the sky power wave eliminating block in Taiwan, and the sky power piece in Taiwan be in the eighties on the basis of the various Dewave blocks that disappear of Japan through repeatedly producing a kind of new improved form behind the experimental study, its performance various wave eliminating blocks of Japan all makes moderate progress, but in recent years along with port construction constantly to maximize, deep waterization and towards the area development of natural conditions difference, existing many blocks have exposed in the disappear defective and the deficiency of aspects such as unrestrained performance, stability and intensity.

The purpose of this utility model is not enough specially to propose this programme-------doubie-column type wave eliminating block, it has novel structure, the advantage of unrestrained superior performance, material saving and good stability disappears for what overcome that aforesaid wave eliminating block commonly used remains.

By as above design, the doubie-column type wave eliminating block that this programme provided is characterised in that: it is the geosynclinal block of rectangle, at openend and middle part one pillar is arranged respectively, all has half slotted hole of symmetry on the sideline on the two sides of frid up and down.

In this programme, the cross section of its geosynclinal block openend pillar is a Long Circle, and its long axis direction is vertical with the center line on rectangle block length limit, and the cross section of bilge cod is a Long Circle in the geosynclinal block, and its long axis direction is parallel with the center line on rectangle block length limit.The corresponding data of two half slotted holes that the major diameter of two half slotted holes of leaving at last frid and minor axis are all left less than frid down.

Adopt this programme can embody following superiority: 1. this doubie-column type wave eliminating block is through piling up the quaywall that can make harbour as basic building block, shore protection or mole are used, the opening of flute profile is met outwardly to wave when piling up, complete rear portion connects the landing field, the boundary line of levels geosynclinal block interlaces when piling up, and to arrange the difference half-block wide, bottom is rebasing with the underwater level land of special square, neatly pile up the formation quaywall layer by layer continuously closely, because every wave eliminating block is all below 30 tons, as long as the bottom surface is carried out and be connected its stability behind with land is well, compare in stability with sky power piece, all have on application life and the economic benefit significantly and improve; 2. each wave eliminating block is piled up continuously, former and later two pillars are except having the supporting role the cell body opening in the block, cooperate with the semicircle orifice of cell body top and bottom and to have formed the unrestrained chamber that promptly disappears, the space that communicates about quaywall inside communicates up and down, wave rushes at the bank and enters the unrestrained chamber that disappears, at the vortex of unrestrained indoor generation level and the vertical vortex of disappearing, form and impact and friction, make it to have consumed most wave energy, obtained the good unrestrained effect that disappears, to the measurement of reflected energy, the reflectance factor of this doubie-column type wave eliminating block is lower than day index of correlation of power piece to warp before bank; 3. this wave eliminating block modern design uniqueness surfaces and partly gives sensation attractive in appearance and enjoyment; 4. it has that performance is good, simple in structure, modern design is unique through the practical proof of preproduction, is worth of widely use.

Fig. 6 is the structural representation of doubie-column type wave eliminating block when being used for bulkhead wall.

Fig. 7 is the ordered state figure when piling up.

Fig. 8 is the outside drawing of the sky power piece in the prior art.

The embodiment of existing accompanying drawings this programme.This doubie-column type wave eliminating block is the rectangle geosynclinal block of reinforced concrete prefabricated one-tenth, at the opening part and the middle part of cell body one pillar is arranged respectively, all has half slotted hole of symmetry on two sidelines of cell body upper and lower plates.The major diameter of the semicircle orifice of leaving on the following frid and minor axis are all greater than the numerical value of slotted hole on the last frid.In the cross section of cell body opening part pillar is Long Circle, and the center line on the long limit of its long axis direction and rectangle block is perpendicular, and the cross section of bilge cod also is a Long Circle in the cell body, the long limit of its major axis and block central lines.In order can withstand shock to increase its life-span and to keep its complete morphology, on the face of heading sea of frid up and down, make bigger chamfering, in order to increase intensity at the ribs of also having done projection before and after the perforation down between frid upper supporting column and drop end.

During use, its drop end is connected with the soil on bank, below rebasing with special square, each wave eliminating block is neatly piled up closely, the boundary line on the long limit of each interlayer wave eliminating block interlaces and arranges the phase difference of half length of side, ready-made like this quaywall inside just formed and communicated up and down, about the unrestrained chamber that promptly disappears, the space that communicates, the feasible unrestrained chamber that disappears communicates with the external world between the pillar in quaywall front, when wave rush at the bank enter disappear the wave indoor, form and laterally reach vortex up and down, consume a large amount of wave energy through impacting, rubbing, caused the unrestrained effect that well disappears.The big I that planar survey reflects unrestrained energy before quaywall obtains reflectance factor, and after measured: the reflectance factor that regular waves obtains in doubie-column type wave eliminating block is 0.40～0.76, and the regular wave reflectance factor of day power wave eliminating block is 0.52～0.78; The reflectance factor that irregular wave action obtains in doubie-column type wave eliminating block is 0.49～0.78, and the reflectance factor of day power wave eliminating block is 0.66～0.80, and the visible topmost unrestrained performance that disappears is better than day index of power wave eliminating block.In addition, all greater than sky power wave eliminating block, and all there is bigger plane the top and bottom of block to doubie-column type wave eliminating block in single block weight and void content, and therefore stability is also given prominence to.The pilot sample of this programme has proved that through experiment and strict detection the product of this programme has aforesaid every advantage, is worthy of promotion and application.
