Description
Technical field
This utility model relates to a kind of cofferdam structure.
Background technology
Cofferdam refers in hydraulic engineering construction, and for building permanent water conservancy projects, that builds provisional encloses
Protection structure.Its effect be prevent water and soil enter building build position, in order at cofferdam internal drainage,
Excavation pit, builds building.Typically it is mainly used in waterwork, except as the one of formal building
Outside part, cofferdam is typically removed after being finished.When building harbour, for creating the dry construction condition of little scope,
I.e. need to make above-mentioned cofferdam structure.But compared to the lake of land, the current in bay are increasingly complex,
Current in bay are bigger to the impact of cofferdam structure, it is therefore desirable to a kind of resistance to impact of design is more preferable,
The higher cofferdam structure of intensity.
Utility model content
It is more preferable that this utility model has designed and developed a kind of resistance to impact, the higher cofferdam structure of intensity.
The technical scheme that this utility model provides is:
A kind of cofferdam structure, including:
Cofferdam main body, it is cascading by multiple packed layers, and in multiple packed layer soil packed layer and
Soil stone packed layer is intervally installed, and wherein, described soil stone packed layer is to be formed by multiple soil stone obturators,
Described soil stone obturator for by steel wire mesh bag built-in banket with stone made by；
Wherein, in the outside of described cofferdam main body, nestle up the lateral surface of described cofferdam main body and be provided with and cover
Cover the protective layer of the lateral surface of described cofferdam main body, described protective layer by being formed by multiple stone obturators,
Described stone obturator is for by made by a built-in rocking of steel wire mesh bag.
Preferably, in described cofferdam structure, the thickness of described soil packed layer is 20～30cm, described
The thickness of soil stone packed layer is 50～70cm.
Preferably, in described cofferdam structure, the thickness of described protective layer is 20～30cm.
Preferably, in described cofferdam structure, between adjacent two packed layers, also it is horizontally arranged with first
Stiffener, described cofferdam structure is additionally provided with the second reinforcement running through multiple packed layer from the top down,
Described first reinforcement and described second reinforcement are fixedly attached to one another.
Preferably, in described cofferdam structure, the steel wire mesh bag of described stone obturator is fixedly attached to
One end of lacing wire, described lacing wire fills in the main body of described cofferdam.
Cofferdam structure described in the utility model is made up, at cofferdam structure of soil packed layer and soil stone packed layer
Lateral surface be provided with a protective layer, this protective layer by being formed by multiple stone obturators, stone fill
Body is for by made by a built-in rocking of steel wire mesh bag.I.e. when the water impact cofferdam structure in bay
Time, water impact is in retaining layer, owing to the stone in stone obturator is in a kind of loose state,
It is easier to offset the impulsive force of current, and then provides protection for cofferdam main body.Cofferdam of the present utility model is tied
Structure is more resistant to impact, and intensity is more preferable.
Accompanying drawing explanation
Fig. 1 is the structural representation of cofferdam structure described in the utility model.
Detailed description of the invention
Below in conjunction with the accompanying drawings this utility model is described in further detail, to make those skilled in the art
Can implement according to this with reference to description word.
As it is shown in figure 1, this utility model provides a kind of cofferdam structure, including cofferdam main body 5, its by
Multiple packed layers are cascading, and in multiple packed layer soil packed layer 1 and soil stone packed layer 2 be each other
Interval is arranged, and wherein, described soil stone packed layer 2 is to be formed by multiple soil stone obturators, and described soil stone is filled out
Fill body for by banketing and made by stone steel wire mesh bag is built-in；Wherein, in described cofferdam main body
Outside, nestle up the lateral surface of described cofferdam main body and be provided with the guarantor of the lateral surface covering described cofferdam main body
Sheath 4, described protective layer 4 is by being formed by multiple stone obturators 3, and described stone obturator is served as reasons
Made by a built-in rocking of steel wire mesh bag.
In this utility model, soil packed layer and soil stone packed layer are intervally installed, to form bulk strength
Good cofferdam main body.This utility model the most all uses soil packed layer to make cofferdam main body, but still permissible
Cofferdam structure is kept to have good intensity.This is because, this utility model sets in the outside of cofferdam main body
Put protective layer, this protective layer essence be filled in steel wire mesh bag by stone in formed, i.e. stone is in phase
To loose state.When water impact on the protection layer time, the impulsive force of current can be in loose condition (of surface)
Stone offset, and then avoid cofferdam main body and bear the impulsive force of current.This utility model improves
The resistance to impact of cofferdam structure, reduces the cost of manufacture of cofferdam structure.
Preferably, in order to improve the bulk strength of cofferdam structure further, in described cofferdam structure,
The thickness of described soil packed layer 1 is 20～30cm, and the thickness of described soil stone packed layer 2 is 50～70cm.
Preferably, in order to preferably offset the impulsive force of current, strengthen the resistance to impact of cofferdam structure,
In described cofferdam structure, the thickness of described protective layer 4 is 20～30cm.
Preferably, in order to improve the bulk strength of cofferdam structure further, in described cofferdam structure,
Also be horizontally arranged with the first stiffener between adjacent two packed layers, described cofferdam structure be additionally provided with from
On downward through the second reinforcement of multiple packed layers, described first reinforcement and described second reinforcement that
This is fixed together.
Preferably, in described cofferdam structure, the steel wire mesh bag of described stone obturator is fixedly attached to
One end of lacing wire, described lacing wire fills in the main body of described cofferdam.
Although embodiment of the present utility model is disclosed as above, but it is not restricted to description and reality
Executing listed in mode utilization, it can be applied to various applicable field of the present utility model completely, for
For those skilled in the art, it is easily achieved other amendment, therefore without departing substantially from claim
And under the general concept that limited of equivalency range, this utility model is not limited to specific details and shows here
The legend gone out and describe.
