Abstract
The utility model relates to a flow intercepting steel box structure which comprises container type steel structural empty boxes, an exhaust hole, a sand removing hole, a blowing filling hole, blowing filling sand and air bags. The two steel structural empty boxes are fixedly connected into integral structures of clamping buckles, the blowing filling sand is filled in the structures of the empty boxes, and the air bags used for leveling and water blocking are fixed at the bottom of the boxes. By adopting the steel box structure, the capability of resisting the flushing of water flow is greatly improved after the sand is filled and compacted. The flow intercepting steel box structure has high safety degree and can adapt to severe hydrologic conditions.
Description
Technical field
The utility model belongs to the closure work in corral (making ground or the embankment) engineering, is specifically related to a kind of Longkou closure structure and job practices thereof.
Background technology
In the tidal river or marine site when carrying out corral (make ground or embankment) engineering, must be through the most important link of whole engineering-carry out Longkou (mouthful door) closure work.Usually the closure body structure pattern that adopts has hydraulic reclamation packeted soil rib body and rock mound at present.At corral area big (the Longkou Kou Men turnover water yield is bigger), when mouthful door is big, if adopt conventional hydraulic reclamation packeted soil rib body to exist:
(1) no matter adopt flat, upright blocking up, when flow velocity was big, cloth bag was in place, the filling difficulty of construction is big;
When (2) adopting flat blocking up, mouthful door is big, and hydraulic reclamation engineering quantity waterborne is big, and construction and ship organize difficulty big;
(3) when closure requires to carry out in neap season, and must accomplish without any letup, otherwise in entering, spring tide, cloth bag is difficult to bear washing away of high flow rate, and the Longkou engineering is had great risk;
(4) under water during hydraulic reclamation, banketing can't compacting, and unit weight is less, and required section is often bigger, and closure intensity increases suddenly, need organize in a short time than adult, material, machine, and difficulty is bigger.
And adopt common rock mound:
When (1) flow velocity is big, must could satisfy the anti-impact requirement by the boulder particle diameter, strengthen buying, transportation, throw and fill out difficulty;
(2) adopt flatly when stifled, mouthful door is big, and it is big that engineering quantity is filled out in throwing waterborne, and construction and ship organize difficulty big;
(3) in the rock mound closure, before not holding one's breath, there is the problem of seepage stability all the time, in case unstability, the very big risk that there is comprehensive avalanche in the rib body, destroys by rush of water.
The utility model content
Technical problem to be solved in the utility model provides a kind of Longkou closure (damming) structure and job practices thereof, makes that construction adaptability is strong, reusable, easy construction is quick, economical.
In order to solve the problems of the technologies described above, the technical scheme that the utility model adopted is: a kind of steel box structure that dams, be used for Longkou steel case blast lifting closure, it comprises: steel work casing, the gas avert by prayers that is positioned at the some through holes on the steel work casing and is fixed in steel work casing bottom, it is characterized in that: described steel work casing is divided into two-layer up and down, promptly the 1st layer and the 2nd layer, be provided with some through holes on the steel plate between described the 1st layer and the 2nd layer, the relative both sides of described steel work casing are provided with opening.
As one of preferred version of the present utility model, the described steel box structure that dams comprises 2 interconnective steel work casings.
As one of preferred version of the present utility model, described steel work casing adopts buckle structure to connect.
As one of preferred version of the present utility model, the 1st layer and the 2nd layer of described steel work casing is equipped with sand.
Owing to adopted technique scheme, had following advantage:
1, owing to adopt the steel box structure, fill the sand ballast after anti-current scour ability improve greatly, can adapt to more abominable hydrologic condition, the degree of safety height.
2. closure material, one. be the steel case that can reuse, the 2nd, abundant and cheap silt particle, energy-conservation, economize material, environmental protection.
3, the steel box structure can adopt " container-type " empty van structure, is convenient to making, handling and stacking;
4, because the steel box structure can fill the sand ballast, possess stronger self-stability, therefore this novel structure has better compliance and feasibility;
5, adopt this closure steel box structure, the corresponding reduction of difficulty of construction, effective accelerating construction progress, duration shortening.
6, fine-tuning leveling steel case after the filling of gas avert by prayers also can play plugging function, and it is strong therefore to adapt to the out-of-flatness ability, states and can reduce water leakage.
7, after the closure, the recyclable utilization of steel box structure.
