Detailed Description

The present invention will be further explained with reference to the drawings attached to the specification.

As shown in fig. 1 to 5, the assembled cofferdam comprises a cofferdam body 10, an inserting part 20 and a first sealing part 30, and each part and the relationship among the parts are explained in detail as follows:

the end of the cofferdam plate body 10 is provided with a first groove 11, preferably, both ends of the cofferdam plate body 10 are provided with first grooves 11. The weir plate body 10 comprises a keel 12, aluminum plates or alloy plates 13 and a filling component 14, the keel 12 is arranged at the end part of the weir plate body 10 at least, the keel 12 positioned at the end part of the weir plate body 10 is provided with a first groove body 11 and a lower end connecting piece 15, the aluminum plates or the alloy plates 13 are respectively fixed on the front end surface and the rear end surface of the keel 12, and the filling component 14 is filled between the two adjacent keels 12 and the aluminum plates or the alloy plates 13.

The cofferdam plate body 10 is made of the aluminum plate or the alloy plate 13, the alloy plate is preferably made of aluminum alloy, preferably, the keel 12 is also made of aluminum or aluminum alloy, the aluminum or aluminum alloy is lighter than a steel plate in weight, the overall quality of the cofferdam plate body 10 is much lighter than that of a steel sheet pile in the prior art, and the aluminum or aluminum alloy cannot be corroded after meeting water, so that the service life of a product is guaranteed easily.

Further, the filling member 14 is disposed inside the weir plate body 10, and the filling member 14 is advantageous for securing the strength of the weir plate body 10. Preferably, the filling member 14 is an aluminum honeycomb or an aluminum alloy honeycomb, which has the advantages of light weight and good strength and is made of the same material as the aluminum plate or the alloy plate 13, so that electrochemical corrosion between the filling member 14 and the aluminum plate 13 due to the difference in material does not occur.

The keel 12 is also arranged in the middle of the slice body 10. The middle and end portions are provided with such keels 12 so that the strength of the slice body 10 is ensured, preferably the keels 12 are formed by casting, and for cost reduction, the keels 12 in the middle and the keels 12 in the end portions are made by using the same secondary mould, i.e. each keel 12 has said first groove.

One end of the lower end connecting member 15 is fixed to the lower end of the aluminum or alloy plate 13. The lower end connecting member 15 is preferably made of aluminum or an aluminum alloy, and after the lower end connecting member 15 is fixed to the lower end of the aluminum plate or the alloy plate 13, the lower end connecting member 15 forms a seal with the aluminum plate or the alloy plate 13, for example, the lower end connecting member 15 is fixed to the lower end of the aluminum plate or the alloy plate 13 by welding. The other end of the lower end connecting piece 15, which is used for being inserted into the mud, is conical, and the lower end connecting piece 15 with the structure not only is convenient to be inserted into the mud, but also is labor-saving when being pulled out of the mud, namely, the lower end connecting piece 15 has the advantage of being easy to insert and pull out.

An upper end connecting piece 16 is further fixed at the upper end of the cofferdam plate body 10, and the upper end connecting piece 16 and the keel 12 are made of the same structure and material. Thus, after the keel 12, the aluminum plate or alloy plate 13, the lower end connector 15 and the upper end connector 16 are connected (all by welding), a cavity is formed between the parts, and the filling member 14 is installed in the cavity.

The second groove bodies 21 are arranged on the inserting part 20, and in this embodiment, it is preferable that the second groove bodies 21 are arranged at both ends of the inserting part 20, so that the inserting part 20 preferentially forms an i-shaped structure, and thus, both ends of the inserting part 20 can be assembled with the end portion of one of the weir plate bodies 10.

After the end of the cofferdam plate body 10 is inserted into the second groove 21, an accommodating cavity a is formed between the cofferdam plate body 10 and the inserting member 20, and the first sealing member 30 is arranged in the accommodating cavity a to seal the joint of the cofferdam plate body 10 and the inserting member 20. The first sealing member 30 is a capsule filled with a gas or liquid medium, and preferably, the capsule is made of rubber.

In this embodiment, the sealing structure formed by the first sealing member 30 to the cofferdam plate body 10 and the inserting member 20 is adopted, and since the first sealing member 30 adopts a capsule filled with a gas or liquid medium, the first sealing member of such a structure can be tightly attached to the inner wall surface of the accommodating cavity a, and has an advantage of good sealing effect. Because the weir plate body 10 is firstly jointed with the inserting part 20, although water is accumulated in the accommodating cavity A, after the capsule is put into the accommodating cavity and is filled with gas or liquid medium, the water in the accommodating cavity A is extruded out of the accommodating cavity A by the extrusion force generated by the gas or liquid medium, the capsule is continuously expanded and deformed along with the continuous filling of the medium, and finally the capsule is jointed with the inner wall surface of the accommodating cavity A, so that the capsule and the inner wall surface of the accommodating cavity A have the advantage of good sealing effect.

The cofferdam plate is characterized by further comprising a second sealing part 40, the second sealing part 40 is arranged on the outer wall of the end part of the cofferdam plate body 10 and/or the inner wall of the first groove body 11, and the cofferdam plate body 10 and the second groove body 21 are further sealed through the second sealing part 40. The second sealing member 40 is rubber. By the second sealing member 40, the sealing performance is further improved, and the pressure of water acting on the first sealing member 30 is reduced, so that the safety of the first sealing member 30 is ensured.

Finally, it should be noted that: the above embodiments are only preferred embodiments of the present invention to illustrate the technical solution of the present invention, not to limit the same, and not to limit the scope of the present invention; although the present invention has been described in detail with reference to the foregoing embodiments, it should be understood by those skilled in the art that: the technical solutions described in the foregoing embodiments may still be modified, or some or all of the technical features may be equivalently replaced; the modifications or the substitutions do not make the essence of the corresponding technical solutions depart from the scope of the technical solutions of the embodiments of the present invention; in addition, will the technical scheme of the utility model direct or indirect application is in other relevant technical field, all including on the same reason the utility model discloses an in the patent protection scope.
