Description

Technical Field

[0001] The utility model relates to the field of cofferdams, in particular to a combined movable cofferdam for embankment hazard removal and reinforcement. Background Art

[0002] A cofferdam is a temporary retaining structure used in water conservancy project construction to support permanent water conservancy facilities. Its purpose is to prevent water and soil from entering the building's construction site, allowing drainage, excavation, and construction within the cofferdam. It is typically used in hydraulic structures. Unless it is part of a formal structure, a cofferdam is typically dismantled after use. To ensure the economical reuse of cofferdams, modular mobile cofferdams are often used. These cofferdams serve both to prevent water and retain water, while also supporting the foundation pit walls.

[0003] When the existing combined movable cofferdam is assembled and installed, bolts, connecting rods and other components are usually used to assemble and connect multiple cofferdam components. During the assembly and connection, rubber pads and other sealing devices need to be padded at the joints to prevent water from penetrating the cofferdam through the gaps. Although this method can meet the conventional anti-seepage requirements, during the assembly period of the cofferdam or during the use of the cofferdam after assembly, if the cofferdam undergoes unexpected slight vibration or slight displacement, the water-blocking effect of the rubber pads and other sealing devices at the gaps will be greatly reduced, which will still lead to water penetration, resulting in the overall water-blocking effect of the combined movable cofferdam being unsatisfactory. Utility Model Content

[0004] The technical problem to be solved by the utility model is to provide a combined movable cofferdam for embankment hazard removal and reinforcement, which adopts a filling air bag that can be supplemented with gas to expand it to fill and block the gaps caused by accidental vibration displacement of the cofferdam.

[0005] The present invention is realized through the following technical scheme: The present invention proposes a combined movable cofferdam for embankment hazard removal and reinforcement, comprising a cofferdam component one and a cofferdam component two, wherein a slot is provided at the connection between the cofferdam component one and the cofferdam component two, the cofferdam component one and the cofferdam component two are matched through the slot, and the cofferdam component one and the cofferdam component two are bonded with rubber gaskets in the slot, and are characterized in that: the cofferdam component one and the cofferdam component two are both provided with a hollow chamber at the middle intersection of the slot, the hollow chambers on the cofferdam component one and the cofferdam component two are circular after combination, the cofferdam component one and the cofferdam component two are connected with filling airbags in the hollow chambers, the filling airbags also have airbag ends and connecting parts, and the filling airbags are connected with inflatable components through the connecting parts.

[0006] By adopting the above technical solution, the inflatable component can replenish gas for the filling airbag. When the cofferdam component one and the cofferdam component two are accidentally slightly vibrated or displaced, the filling airbag can expand with the replenishment of gas, thereby filling the gaps caused by the slight vibration or displacement, ensuring its water-blocking effect.

[0007] Furthermore, the inflatable component is an air pump.

[0008] By adopting the above technical solution, the air pump is equipped with a built-in waterproof power supply, which can efficiently replenish gas for the filling airbag.

[0009] Furthermore, the inflatable component is an air pressure tank.

[0010] By adopting the above technical solution, the air pressure tank contains high-pressure gas, and cooperates with the electronically controlled valve. When the air pressure in the filling airbag drops, the filling airbag can be replenished with gas.

[0011] Furthermore, the filling airbag is a cylindrical rubber airbag.

[0012] By adopting the above technical solution, the deformation and expansion of the filling airbag can better fit the hollow chamber.

[0013] Furthermore, a connecting pipe is inserted into one side wall of the end portion of the airbag, and one end of the connecting pipe is connected to an electronic pressure gauge.

[0014] By adopting the above technical solution, the electronic barometer can detect the air pressure change in the filling airbag.

[0015] Furthermore, the upper end of the cofferdam component 2 is fixedly installed with a bracket 1, the upper end of the cofferdam component 1 is fixedly installed with a bracket 2, the upper end of the bracket 1 is fixedly installed with a support, the supports are distributed in a triangular position, and the inflatable component is fixedly installed in the middle of the upper end of the support.

[0016] By adopting the above technical solution, the installation and connection of the inflatable component can be ensured to be stable.

[0017] Furthermore, support rods are fixedly installed on both sides of the end of the airbag.

[0018] By adopting the above technical solution, the stability of the filling airbag is increased.

[0019] Furthermore, the side walls of the cofferdam component 1 and the cofferdam component 2 are both connected to support rods through hinged seats. The support rods are telescopic rods, the lower ends of the support rods are hinged to a base plate, and the lower end of the base plate is fixedly connected to an insert block.

[0020] By adopting the above technical solution, the support rods can provide a supporting effect for the cofferdam component 1 and the cofferdam component 2.

[0021] Compared with the prior art, the present invention has the following beneficial effects:

[0022] The utility model provides an expandable filling and sealing structure consisting of a filling airbag, an airbag end, a connecting part, a connecting pipe, an electronic barometer and an air pump. During the combined connection period or the use period after the combination, when the cofferdam is subjected to unexpected slight vibration or slight displacement, the gap at the docking will be expanded. At this time, the filling airbag will flexibly deform and expand under the action of the internal stored air pressure, and can fill the expanded gap, thereby ensuring its water-blocking effect and making the overall water-blocking effect of the combined movable cofferdam more ideal.

[0030] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0031] First embodiment: Figure 1-Figure 5 As shown, a combined movable cofferdam for embankment risk removal and reinforcement in this embodiment includes a cofferdam component 1 and a cofferdam component 2, a notch is provided at the connection between the cofferdam component 1 and the cofferdam component 2, the cofferdam component 1 and the cofferdam component 2 are matched through the notch, and a rubber gasket 4 is bonded to the cofferdam component 1 and the cofferdam component 2 in the notch, characterized in that: the cofferdam component 1 and the cofferdam component 2 are both provided with a hollow chamber 5 at the middle intersection of the notch, the hollow chamber 5 on the cofferdam component 1 and the cofferdam component 2 is circular after assembly, and a filling airbag 6 is inserted in the hollow chamber 5 of the cofferdam component 1 and the cofferdam component 2, the filling airbag 6 further having an airbag end 601 and a connecting portion 602, the filling airbag 6 is inserted with an inflatable component through the connecting portion 602, the inflatable component is an air pump 8, and the filling airbag 6 is a cylindrical rubber airbag;

[0032] The hollow chamber 5 of the assembly stroke of the cofferdam component 1 and the cofferdam component 2 2 can block and constrain the filling airbag 6 therein, so that the filling airbag 6 can store a certain air pressure in the hollow chamber 5 without deformation. When the cofferdam component 1 and the cofferdam component 2 2 are accidentally vibrated or displaced, the sealing effect of their connection parts will be greatly reduced. At this time, the hollow chamber 5 will lose its blocking constraint on the filling airbag 6, and the filling airbag 6 will expand and change under the action of its own stored air pressure, so that it can fill the gap caused by the accidental vibration or displacement of the cofferdam component 1 and the cofferdam component 2 2, ensuring the water-blocking effect. The air pump 8 can be used to inject gas into the filling airbag 6 so that the filling airbag 6 stores an appropriate amount of air pressure to meet the kinetic energy requirements of the flexible expansion of the filling airbag 6.

[0033] like Figure 4As shown, a connecting tube 603 is inserted into one side wall of the airbag end 601, and one end of the connecting tube 603 is connected to an electronic barometer 604. The electronic barometer 604 can detect the air pressure change in the filling airbag 6 through the connecting tube 603, and can issue a warning message when the air pressure in the filling airbag 6 reaches the set upper limit or lower limit; when the gap between the cofferdam component 1 and the cofferdam component 2 2 is large due to accidental vibration or displacement, the filling airbag 6 has expanded and deformed under the action of the stored air pressure, and the air pressure inside it will decrease. When it decreases to the set lower limit, the filling airbag 6 will lose its sufficient tight sealing effect and will not be able to ensure its water-blocking effect. Therefore, when the electronic barometer 604 issues a warning message of the set lower limit, the staff can choose to start the air pump 8 to replenish gas for the filling airbag 6 to support the filling airbag 6 to continue to expand and deform and continue to complete the sealing effect, or they can choose to repair and adjust the cofferdam component 1 and the cofferdam component 2 2 in time.

[0034] like Figure 2 and Figure 3 As shown, a bracket 1 701 is fixedly installed on the upper end of the cofferdam component 2, a bracket 2 702 is fixedly installed on the upper end of the cofferdam component 1, and a support 703 is fixedly installed on the upper end of the support 703. The supports 703 are distributed in a triangular position, and the inflatable component is fixedly installed in the middle of the upper end of the support 703 to ensure that the installation and connection of the inflatable component are stable; support rods 605 are fixedly installed on both sides of the airbag end 601, and the support rods 605 can increase the stability of the filled airbag 6.

[0035] like Figure 1 As shown, the side walls of cofferdam assembly 1 and cofferdam assembly 2 2 are connected with support rods 3 through hinged seats 301. The support rods 3 are telescopic rods. The lower ends of the support rods 3 are hinged with base plates 302. The lower ends of the base plates 302 are fixedly connected with plug blocks 303. The support rods 3 can provide lateral support stability for cofferdam assembly 1 and cofferdam assembly 2 2.

[0036] Second embodiment: The difference from the first embodiment is that the inflatable component is an air pressure tank (not shown in the figure), which contains high-pressure gas and can be combined with an electric control valve. When the air pressure in the filling airbag 6 drops, the electric control valve can be opened and the air pressure tank can replenish gas for the filling airbag 6.

[0037] The above description of the disclosed embodiments will enable one skilled in the art to implement or use the present invention. Various modifications to these embodiments will be readily apparent to one skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention is not limited to the embodiments shown herein but is intended to conform to the widest scope consistent with the principles and novel features disclosed herein.
