Description
Technical field
Cofferdam structure is the utility model is related to, more specifically to a kind of double ground-connecting-wall cofferdam structure.
Background technology
Because economic development is rapid, inland river transport rapid growth, the handling capacity and the volume of goods transported of many original ship lock need
Ask incompatible, be badly in need of the original ship lock of upgrading or enlarging second-line shiplock, reorganization and expansion construction often require that do not influence it is existing
The normal operation of ship lock.Lock construction generally requires cofferdam to ensure dry ground condition.
Traditional cofferdam mainly has two kinds, and one kind is earth rock cofferdam, and one kind is concrete cofferdam.Earth rock cofferdam weir crest width one
As be 4~12m, foundation ditch side slope ratio is 1:1.5~1:2.0, the outer side slope ratio of foundation ditch is 1:2.0~1:2.5, cause weir bottom width degree past
It is past very big.Earth rock cofferdam applies in general to the unrestricted engineering of plane figure.Concrete cofferdam typically requires to be laid in carrying
On the preferable ground of power, weir crest width is 3~7m, it is domatic can be vertical, space-consuming is little.But concrete cofferdam construction is in itself
Need to build Temporary Cofferdam, to provide dry ground condition.Temporary Cofferdam can typically take larger space.Traditional cofferdam or it is long-term or
Larger space can be all taken in short term, this may hinder the normal operation of a line ship lock, in some instances it may even be possible to cause a line ship lock to be stopped navigation.
Utility model content
The technical problems to be solved in the utility model is, there is provided one kind saves space, reduces to surrounding constructure influence
Double ground-connecting-wall cofferdam structure.
Technical scheme is used by the utility model solves its technical problem：Construct a kind of double ground-connecting-wall cofferdam knot
Structure, including rigid plate, the rigid plate top are provided with front vertical wall and rear wall, backfill are provided between front vertical wall and rear wall
Material, front vertical wall bottom are provided with drainpipe, and front vertical wall is arranged on the inside of foundation ditch, and rear wall is arranged on the outside of foundation ditch, the rigidity
Plate bottom is provided with front wall and rear wall, and front wall is arranged on the inside of foundation ditch, and rear wall is arranged on the outside of foundation ditch.
By such scheme, the front vertical wall and rear wall are arranged on the top of rigid plate, and front vertical wall is fixed with rigid plate to be connected
Connect, rear wall is fixedly connected with rigid plate.
By such scheme, after the front wall and rear wall is arranged on the bottom of rigid plate, and front wall is fixedly connected with rigid plate, after
Wall is fixedly connected with rigid plate.
By such scheme, the front wall and rear wall are arranged on underground, are underground structure.
By such scheme, the front wall, rear wall, front vertical wall, rear wall and rigid plate are reinforced concrete structure.
Implement double ground-connecting-wall cofferdam structure of the present utility model, have the advantages that：
1st, space needed for double ground-connecting-wall cofferdam structure of the present utility model is smaller, it is not necessary to heavy excavation, to surrounding buildingses
The safety of thing and the influence used are smaller；
2nd, the rigid plate in the utility model can completely cut off the transmission of backfill material weight stress, reduce front wall, the soil pressure of rear wall
Power, reduce front wall, the thickness or reinforcement ratio of rear wall, cost saving；
3rd, the front vertical wall lower end in the utility model is disposed with osculum, drains ponding in backfill material, reduces backfill material pair
The pressure of front vertical wall, rear wall, reduce front vertical wall, the thickness or reinforcement ratio of rear wall, cost saving；
4th, the backfill charge level layer in the utility model can lay pavement structure, be passed through for Construction traffic, public vehicles；
5th, the cofferdam structure in the utility model can be used as dash soil-baffling structure, at the same can also also serve as guide wall, every
Flow the permanent structures such as wall.
Brief description of the drawings
Below in conjunction with drawings and Examples, the utility model is described in further detail, in accompanying drawing：
Fig. 1 is a kind of floor map of double ground-connecting-wall cofferdam structure of the utility model；
Fig. 2 is A-A directions cross section in Fig. 1；
Fig. 3 is B-B directions vertical section in Fig. 1；
Fig. 4 is C-C directions vertical section in Fig. 1.
Embodiment
In order to which the technical characteristics of the utility model, purpose and effect are more clearly understood, it is detailed now to compare accompanying drawing
Illustrate specific embodiment of the present utility model.
As Figure 1-4, double ground-connecting-wall cofferdam structure of the present utility model includes rigid plate 1.
The top of rigid plate 1 is provided with front vertical wall 2 and rear wall 3, and backfill material 4 is provided between front vertical wall 2 and rear wall 3,
The bottom of front vertical wall 2 is provided with drainpipe 5, and drainpipe 5 is distributed along cofferdam axis by certain length.Front vertical wall 2 and rear wall 3
The top of rigid plate 1 is arranged on, front vertical wall 2 is fixedly connected with rigid plate 1, and rear wall 3 is fixedly connected with rigid plate 1, front vertical wall 2
It is arranged on 6 on the inside of foundation ditch, rear wall 3 is arranged on 7 on the outside of foundation ditch.The bottom of rigid plate 1 is provided with front wall 8 and rear wall 9, and front wall 8 is set
Put 6 on the inside of foundation ditch, rear wall 9 is arranged on 7 on the outside of foundation ditch, and front wall 8 is fixedly connected with rigid plate 1, and rear wall 9 is fixed with rigid plate 1
Connection.Front vertical wall 2, rear wall 3, rigid plate 1, front wall 8 and rear wall 9 are reinforced concrete structure.Front wall 8 and rear wall 9 are set
It is underground structure in underground, seepage proof curtain can be also served as, 10 is ground wherein in figure.
Space is smaller needed for the utility model, serves not only as foundation pit supporting construction, while also serves as the ground of Adjacent Buildings
Lower supporting construction, the influence to Adjacent Buildings are also smaller.Rigid plate 1 connects front wall 8, rear wall 9, front vertical wall 2 and stood afterwards respectively
While wall 3, the weight stress transmission of backfill material 4 is completely cut off, has reduced front wall 8, the soil pressure of rear wall 9.The bottom of front vertical wall 2 is set
The drainpipe 5 put, the ponding in backfill material 4 can be drained, the pressure of front vertical wall 2 and rear wall 3 can be reduced.Backfill material 4 can
Pavement structure is laid, is passed through for Construction traffic, public vehicles.The cofferdam structure, avoid traditional cofferdam structure space-consuming very
The shortcomings that big.To occupy little space, it is small to surrounding constructure influence the characteristics of, realize the functions such as dash, earth-retaining, antiseepage, supporting.
Meanwhile cofferdam structure can also serve as the permanent buildings such as guide wall, flow blocking wall, cost saving
Embodiment of the present utility model is described above in conjunction with accompanying drawing, but the utility model is not limited to
The embodiment stated, above-mentioned embodiment is only schematical, rather than restricted, this area it is common
Technical staff is not departing from the utility model aims and scope of the claimed protection situation under enlightenment of the present utility model
