Description

Technical Field

[0001] The utility model relates to the technical field of cofferdams, in particular to a detachable water conservancy construction cofferdam. Background Art

[0002] Cofferdam refers to a temporary enclosure structure built in the construction of permanent water conservancy facilities in water conservancy projects. Its function is to prevent water and soil from entering the construction site of the building so that drainage can be done in the cofferdam, foundation pits can be excavated, and buildings can be built. It is generally used in hydraulic structures. Except as part of a formal building, the cofferdam is generally dismantled after use.

[0003] A Chinese patent with publication number CN217710788U discloses a detachable water conservancy construction cofferdam, which connects the mounting blocks on the cofferdam and the connecting bolts of the support plate together, and then fixes them with fixing nuts. After four support plates and four cofferdams are assembled, the outer grid frame is fixed to the assembled four support plates and four cofferdams, fixed by tightening screws and tightening nuts, and then the insertion rod is fixed to the bottom of the support plate. Finally, the assembled cofferdam is inserted into the construction area through the insertion rod.

[0004] The device uses an external mesh frame to reinforce the assembled cofferdam. Although it can improve the stability of the cofferdam structure itself, since the cofferdam needs to withstand the impact of water when installed in water, it is difficult to ensure the stability of the cofferdam in water by relying solely on four plug rods. In addition, the cofferdam is only installed on the support plate by means of protrusions, which makes the sealing between the cofferdam and the support plate poor and prone to water leakage. Utility Model Content

[0005] In view of this, the purpose of the utility model is to provide a detachable water conservancy construction cofferdam, which effectively solves the problem that after the existing cofferdam is installed in the water, it is difficult to ensure the stability of the cofferdam in the water by relying only on four plug rods, and the cofferdam is only installed on the support plate by means of protrusions, which makes the sealing between the cofferdam and the support plate poor and prone to water leakage.

[0006] In order to achieve the above-mentioned purpose, the technical solution adopted by the utility model is: a detachable water conservancy construction cofferdam, comprising:

[0007] At least four guardrails, one side of the guardrail is provided with a first connecting groove, the other side of the guardrail is fixedly connected with a first protrusion, and the four corners of the guardrail are provided with a first waterproof groove.

[0009] The sealing component can be detachably installed in a first groove formed by splicing two first connecting grooves or in a second groove formed by splicing the first connecting groove and the second waterproof groove.

[0010] The enclosure assembly can be detachably installed on the wall formed by the guardrail and the L-shaped upright poles to resist water impact on the guardrail and the L-shaped upright poles.

[0011] Further, the first connecting groove matches the first waterproof groove and the second protrusion, and the second connecting groove matches the first protrusion and the second protrusion.

[0012] Furthermore, the sealing assembly includes a filling block, to which a waterproof sticker is fixedly connected.

[0013] Furthermore, the enclosure assembly includes a reinforcement rod, a first connecting block is fixedly connected to the guardrail, a first socket is provided on the first connecting block, two second connecting blocks are fixedly connected to the L-shaped vertical rod, a second socket is provided on each of the two second connecting blocks, and the middle section of the reinforcement rod is plugged into the first connecting block and the second connecting block through the first socket and the second socket.

[0014] Furthermore, a limiting nut is threadedly connected to the reinforcement rod, a sleeve is slidably connected to the reinforcement rod, and a support rod is fixedly connected to the sleeve.

[0015] Furthermore, the bottom surface of the L-shaped vertical pole is fixedly connected with an insertion rod.

[0016] The beneficial effects of the above technical solution are:

[0017] The utility model forms a square cofferdam structure with the guardrail and the L-shaped vertical pole through the first protrusion, the first connecting groove, the second protrusion and the second connecting groove through the matching arrangement among the first connecting groove, the first protrusion, the first waterproof groove, the second protrusion, the second connecting groove and the sealing component. Under the action of the first waterproof groove, the second waterproof groove and the sealing component, the connection between the guardrail and the L-shaped vertical pole is waterproofly sealed again, which can effectively prevent water from seeping out from the gap between the guardrail and the L-shaped vertical pole or between the guardrails, and prevent the cofferdam from leaking. The cofferdam structure is reinforced again by using the enclosure component, which can not only improve the stability of the cofferdam structure itself, but also reconnect the cofferdam structure with the bottom of the water through the enclosure component, thereby enhancing the water impact resistance of the cofferdam structure.

[0024] Reference Figure 1-4 A detachable water conservancy construction cofferdam comprises at least four guardrails 1, at least four L-shaped uprights 7, a sealing assembly and a fencing assembly.

[0025] A first connecting groove 3 is provided on one side of the guardrail 1, a first protrusion 2 is fixedly connected to the other side of the guardrail 1, and first waterproof grooves 4 are provided at the four corners of the guardrail 1. The guardrail 1 is made of anti-corrosion material and has a long service life in water.

[0026] A second protrusion 8 is fixedly connected to one side of the L-shaped vertical rod 7, a second connecting groove 9 is opened on the other side of the L-shaped vertical rod 7, and second waterproof grooves 10 are opened at the four corners of the L-shaped vertical rod 7. The first connecting groove 3 matches the first waterproof groove 4 and the second protrusion 8, and the second connecting groove 9 matches the first protrusion 2 and the second protrusion 8.

[0027] When it is necessary to splice the guardrail 1 with the L-shaped upright 7, the guardrail 1 can be spliced ​​through the first protrusions 2 and the first connecting grooves 3 at both ends according to the required number of guardrails 1 to form a plate-like structure, and then the plate-like structure can be installed on the two L-shaped uprights 7 through the first protrusions 2, the first connecting grooves 3, the second protrusions 8 and the second connecting grooves 9.

[0028] The bottom surface of the L-shaped vertical pole 7 is fixedly connected with an insertion rod 13, and the bottom surface of the insertion rod 13 is a pointed end, so that the insertion rod 13 on the L-shaped vertical pole 7 can be inserted into the ground, thereby processing the L-shaped vertical pole 7 to be positioned underwater.

[0029] The sealing component can be removably installed in a first groove formed by splicing two first connecting grooves 3 or in a second groove formed by splicing the first connecting groove 3 and the second waterproof groove 10. The sealing component includes a filling block 14, and a waterproof sticker 15 is fixedly connected to the filling block 14. The filling block 14 can be inserted into the first groove formed by splicing the two first connecting grooves 3 or in the second groove formed by splicing the first connecting groove 3 and the second waterproof groove 10, so that the filling block 14 and the waterproof sticker 15 can be used to fill the gap generated when adjacent railings 1 are spliced ​​or the gap generated when the railing 1 and the L-shaped vertical pole 7 are spliced, thereby enhancing the sealing between the railings 1 and the railings 1 or the railings 1 and the L-shaped vertical pole 7.

[0030] The enclosure assembly can be detachably installed on the wall formed by the guardrail 1 and the L-shaped upright 7, and is used to protect the guardrail 1 and the L-shaped upright 7 from water impact. The enclosure assembly includes a reinforcement rod 16. A first connecting block 5 is fixedly connected to the guardrail 1, and a first socket 6 is provided on the first connecting block 5. Two second connecting blocks 11 are fixedly connected to the L-shaped upright 7, and a second socket 12 is provided on the two second connecting blocks 11. The middle section of the reinforcement rod 16 is plugged into the first connecting block 5 and the second connecting block 11 through the first socket 6 and the second socket 12.

[0031] The guardrail 1 is spliced ​​with the L-shaped vertical pole 7 to form a square cofferdam, and one end of the reinforcement rod 16 is passed through the first and second sockets 6 and 12 and inserted into the first connecting block 5 and the second connecting block 11 to form a planar guardrail, thereby improving the water resistance of the surface.

[0032] A limit nut 17 is threadedly connected to the reinforcement rod 16, and a sleeve 18 is slidably connected to the reinforcement rod 16. A support rod 19 is fixedly connected to the sleeve 18. The limit nut 17 is spirally moved on the reinforcement rod 16, and the two limit nuts 17 are respectively abutted against the two second connecting blocks 11, so as to fix the connection between the guardrail 1 and the L-shaped vertical pole 7, thereby enhancing the structural strength of the cofferdam structure itself. After the sleeve 18 is rotated on the reinforcement rod 16, the support rod 19 can be inserted into the ground, thereby supporting the cofferdam structure again.

[0033] Working principle: First, connect the head and tail of adjacent guardrails 1, that is, insert the first protrusion 2 into the first connecting groove 3 to form a plate-like structure. Then, according to the size of the required construction area, place L-shaped poles 7 at the four corners of the construction area, and insert the insertion rod 13 on the L-shaped pole 7 into the ground. Subsequently, insert the first protrusion 2 at one end of the plate-like structure into the second connecting groove 9, and install the other end of the plate-like structure on the second protrusion 8 through the first connecting groove 3, so that the guardrail 1 and the L-shaped pole 7 form a square cofferdam. Then, insert the filling block 14 into the first groove formed by the two first connecting grooves 3 or the second groove formed by the first connecting groove 3 and the second waterproof groove 10, so that the gaps generated when adjacent guardrails 1 are spliced ​​or the guardrails 1 can be filled with the filling block 14 and the waterproof sticker 15. The gap generated when splicing with the L-shaped vertical pole 7 is filled to enhance the sealing between the guardrail 1 and the guardrail 1 or the guardrail 1 and the L-shaped vertical pole 7. Finally, one end of the reinforcement rod 16 is passed through the first hole 6, the second hole 12 and the sleeve 18 and inserted into the first connecting block 5 and the second connecting block 11 to form a planar guardrail. Then the two limit nuts 17 are respectively abutted against the two second connecting blocks 11 to fix the connection between the guardrail 1 and the L-shaped vertical pole 7, thereby enhancing the structural strength of the cofferdam structure itself. After the sleeve 18 is rotated on the reinforcement rod 16, the support rod 19 can be inserted into the ground, thereby supporting the cofferdam structure again, which not only improves the stability of the cofferdam structure itself, but also enables the cofferdam structure to be reconnected to the bottom of the water through the enclosure assembly, thereby enhancing the water impact resistance of the cofferdam structure.
