Abstract
The utility model discloses a bearing steel plate earth-rock combination cofferdam structure which comprises a cofferdam body and a banket, wherein the cofferdam body comprises an internal structure and an external structure. The bearing steel plate earth-rock combination cofferdam structure has the advantages of high strength, fine stability, scouring resistance and impermeability, and is applicable to the technical field of hydraulic and hydroelectric engineering.
Description
Technical field
The utility model belongs to the Hydraulic and Hydro-Power Engineering technical field, relates to a kind of cofferdam structure, particularly a kind of steel plate soil stone combined cofferdam structure of holding.
Background technology
Along with progress, the development of city of society, engineering construction is more and more, and some engineerings will be crossed over zones such as river or straits.Normally carry out in order to construct, we just need build the cofferdam in water.But existing cofferdam form tends to during construction period and operation, take place the cofferdam to collapse and phenomenon such as cofferdam infiltration.The particular problem that present stage exists:
(1) bottom, cofferdam is impacted by seawater, and well damage causes the cofferdam loss of strength;
(2) impervious wall seeps water easily, and concrete breaks, damages under building stones impact;
(3) construction is chaotic, and the construction period is long, construction period accident take place frequently.
The utility model content
The purpose of the utility model is to overcome above-mentioned technological deficiency, provides that a kind of intensity is big, good stability, erosion control and the impervious steel plate soil stone combined cofferdam structure of holding.Its technical scheme is:
A kind of steel plate soil stone combined cofferdam structure of holding; Said cofferdam structure is divided into cofferdam main body and spats 12 two parts; Wherein the cofferdam main body is made up of internal construction and external structure again, and internal construction mainly is an impervious wall, and external structure comprises zone 7,8,9,10,11.
The side slope gradient outside the outer side slope gradient of above-mentioned spats and the cofferdam >=1: 1.5, wherein zone 1 and zone 2 interior grade of side slope >=1: 1.4.
Further preferred, zone 1,2,5,6 is the building stones that cut into a mountain, and zone 3,4 is the building stones that cut into a mountain of particle diameter≤10cm.
Above-mentioned spats zone 12 and zone 7,8,9,10,11 are the piece stone of 100-150kg.
Above-mentioned impervious wall is built-in steel board concrete wall, and the impervious wall top is to regional 5 tops, and lower end mud to the cofferdam is inner.
Compared with prior art, the beneficial effect of the utility model is:
1. the utility model holds steel plate soil stone combined cofferdam structure when having strengthened seepage prevention of cofferdam property, has improved cofferdam stability;
2. when the technical scheme of the utility model strengthens cofferdam stability is the reduction of erection time condition to be provided, and then has reduced construction costs;
3. the utility model cofferdam raw material are clearer and more definite, all are conveniently to obtain the building stones that cut into a mountain, for construction provides convenience;
4. the utility model construction is simple, for shortening the construction period condition is provided.
Description of drawings
Fig. 1 is the structural representation of the utility model.
The specific embodiment
Below in conjunction with the accompanying drawing and the specific embodiment the utility model is done explanation in further detail.
With reference to Fig. 1; A kind of steel plate soil stone combined cofferdam structure of holding, said cofferdam structure is divided into cofferdam main body and spats 12 two parts, and wherein the cofferdam main body is made up of internal construction and external structure again; Internal construction mainly is an impervious wall, and external structure comprises zone 7,8,9,10,11.The outer side slope gradient in spats zone 12 and the outer side slope gradient in cofferdam >=1: 1.5, wherein zone 1 and regional 2 interior grade of side slope >=1: 1.4.Zone 1,2,5,6 is the building stones that cut into a mountain, and zone 3,4 is the building stones that cut into a mountain of particle diameter≤10cm.Spats 12 and zone 7,8,9,10,11 are the piece stone of 100-150kg.Impervious wall is built-in steel board concrete wall, and the impervious wall top is to regional 5 tops, and lower end mud to the cofferdam is inner.
The construction of the utility model is following:
1) at first set up pontoon bridge, utilize pontoon bridge successively step-by-step accurately jettisoning and meet zone 1 and the regional 2 places building stones that cut into a mountain, wherein outer side slope >=1: 1.5, interior side slope >=1: 1.4.
2) utilize pontoon bridge, accurately jettisoninging of step-by-step meets the building stones that cut into a mountain in zone 3, the particle diameter≤10cm of building stones, and wherein regional 3 elevations are for being higher than seabed or river bed 3-4m.
3) utilize the groover fluting of position shown in the A in the drawings, and build the built-in steel plate concrete impervious wall that holds, it highly arrives regional 3 tops;
4) utilize pontoon bridge, accurately jettisoninging of step-by-step meets the building stones that cut into a mountain in zone 4, and its top elevation is for being higher than seabed or river bed 6-7m, and its side slope is than >=1: 1.5.
5) utilize pontoon bridge, accurately jettisoninging of step-by-step meets the building stones that cut into a mountain in zone 5 and zone 6, the about 2m of its thickness, its side slope than with regional 4 side slope than consistent.
6) utilize the groover fluting of position shown in the B in the drawings, in step 3), on the basis of impervious wall, continue the built-in steel plate concrete impervious wall that holds of building, it highly reaches till regional 5 tops, guarantees that it maintains an equal level with design climax water level at least.
7) utilize pontoon bridge, step-by-step is jettisoninged accurately and is met the building stones that cut into a mountain in spats zone 12 and zone 7,8,9,10,11 successively, and the said building stones that cut into a mountain are the piece stone of 100-150kg, and wherein each regional side slope is than >=1: 1.5.
The above; Be merely the preferable specific embodiment of the utility model; The protection domain of the utility model is not limited thereto; Any technician who is familiar with the present technique field is in the technical scope that the utility model discloses, and the simple change of the technical scheme that obtains or equivalence replacement all fall in the protection domain of the utility model with may be obvious that.
