Description

A kind of structure of sloping breakwater

Technical field

The utility model relates to hydraulic structure, specifically is a kind of structure of sloping breakwater.

Background technology

Sloping breakwater is a kind of common hydraulic structure, and mask is the important component part of sloping breakwater, and mask is determining structural shape, cost and the degree of safety of section, and mask destroys and will cause levee body to damage.The traditional form sloping breakwater adopts the jackstone mask, and the employing header rectangular slab of stone that has is as mask, have simple in structure, easy construction, maintenance easily, advantage such as cost is lower, thereby be widely adopted.This ancient pattern is built the depth of water and little sea area, the waters of wave usually in, is advanced to the depths by the bank.In recent years because the needs of building and using, also to build sloping breakwater in the depth of water sea area that the wave is high, original mask pattern that adopts is because the deadweight of piece stone is little, can not satisfy the homeostasis requirement under wave hits, thereby various bigger concrete irregular blocks just arise at the historic moment as turning round king's word block etc., have replaced traditional structures such as ancient piece stone, the rectangular slab of stone gradually, bigger improvement has appearred in the mask pattern, and applicability is also more extensive.Existing a kind of barrier board of port works specification recommends, member yardstick are roughly about 1 times of the preceding wave height of dike, and the member yardstick is little, every independent stressed, and be lamina, and the unrestrained space that disappears is little, be applicable to the sea area that wave is little, or use as river bottom protection, actually rare as the example that the mole mask uses.

Its mask of the sloping breakwater of above-mentioned all patterns all is made up of independently single block separately in a word, the stability of mask and then the stability that is related to section all depend on whether stablizing of single block, if single block instability, mask instability then, and then section also can lose stable, even the safety that jeopardizes whole mole.Therefore, ground surface protection structure is most important for sloping breakwater.

The tradition sloping breakwater mainly is made up of sloping top wave wall, mask and sloping base concrete town pin piece three parts, and three's structure difference is stressed separately separately, and it is stable to rely on own wt to keep, and structure section is by single component stability control.Since wave hit its striking point of mole, force de frappe with dike before fluctuation in stage change, when water level was high usually, wave was just big, hitting power is also big, striking point is on top, the easiest unstability of wave wall.The wave striking point is near platform in an opposite direction during low water stage, the stressed least favorable of town's pin piece.Wave hits on mask during middle water level, involves 1 times of wave height scope up and down, all belongs to unfavorable stressed position.Under conditions such as certain wave, the depth of water, can not occur wave wall, mask and town's pin piece usually and be subjected to worst wave simultaneously and impact.Enough at section, be unlikely under the situation of whole unstability, structural instability or damage at first appear on wave wall, mask or the town's pin piece usually, and then cause the surface of a wound to enlarge, and cause more havoc.In a word, stressed separately because this structure three parts can not form integral body, thereby defeated in detail easily, this is one of defective of existing structure.

The utility model content

At the problems referred to above, it is more reasonable that the utility model aims to provide a kind of stress performance, section more economically, the structure of the sloping breakwater that whole structural stability and local stability are all higher.

For realizing this technical purpose, scheme of the present utility model is: a kind of structure of sloping breakwater, comprise wave wall, mask and town's pin piece, described mask is by crossbeam, longeron, the crisscross double-decker that is linked to be integral body of grade beam three parts, wherein, longeron is built on stilts, constitutes the unrestrained space that disappears between crossbeam, longeron, the grade beam; Described mask two ends up and down links to each other with wave wall, town's pin block respectively, and it is stressed jointly to constitute whole section mole.

As preferably, the double-decker of described mask is the integral body that per 20 meters one structural sections constitutes; The porosity in the described unrestrained space that disappears is 40%.

The structure of this programme makes wave wall, mask and town's pin piece Trinity, whole stressed, it is stressed and rely on deadweight to keep stable traditional design method to have changed single member, the block of sloping breakwater, be combined into a kind of brand-new sloping breakwater structural shape, have good integrity, anti-strike ability is strong, adopt fabricated construction, construction speed is fast, and engineering quantity is little, characteristics such as cost province.
