Abstract
Description
Technical Field
[0001] This utility model relates to the field of water conservancy engineering technology, specifically a cofferdam device for water conservancy engineering construction. Background Technology
[0002] Water conservancy engineering mainly studies the basic knowledge and skills of engineering hydrology, water conservancy engineering surveying, water conservancy reinforced concrete, hydraulic structures, engineering drawing, etc. In the field of water conservancy engineering, we carry out engineering planning and design, on-site construction, engineering budgeting, and maintenance and repair of water conservancy equipment. Nowadays, cofferdam construction is often used in water conservancy construction.
[0003] A cofferdam is a temporary retaining structure built in hydraulic engineering projects to construct permanent hydraulic facilities. Its function is to prevent water and soil from entering the construction site, allowing for drainage, excavation of the foundation pit, and construction of the structure. It is primarily used in hydraulic engineering structures and, unless part of a permanent building, is generally dismantled after use. The cofferdam's height is higher than the highest water level that may occur during the construction period.
[0004] In the prior art, utility model application number 2023230028867 discloses a cofferdam device for water conservancy engineering construction, including a steel plate cofferdam forming a ring. The steel plate cofferdam includes multiple bases, and each base has a slot in the middle along the vertical direction. Multiple plates are inserted into the slot, and a positioning block is provided in the middle of the bottom of the slot. A positioning groove is provided on the plate to cooperate with the positioning block. The positioning groove is slidably connected to the positioning block. An inclined part is provided at the bottom of the plate, and the inclined part is located on both sides of the bottom of the plate and the bottom of the positioning groove. This solves the problem that the existing integral type is large in size and weight, requiring large machinery to maintain normal use during construction, and cannot be partially assembled according to needs.
[0005] However, in practical applications, due to the depth of some river channels, the height of a single enclosure is insufficient to meet the usage requirements. Furthermore, it is not convenient to add more enclosures on top of the existing ones, and the upper part of the enclosures lacks support, resulting in poor stability, which requires improvement. Utility Model Content
[0006] The technical problem to be solved by this utility model is to overcome the above-mentioned technical defects and provide a cofferdam device for water conservancy engineering construction.
[0007] To solve the above problems, the technical solution of this utility model is: a cofferdam device for water conservancy engineering construction, including columns and multiple baffles, with splicing strips fixed to both sides of the baffles;
[0008] The baffle has ear plates symmetrically fixed to the middle of its inner side, and a horizontal plate is installed on one side of the column. Multiple positioning seats are fixed to the side of the horizontal plate away from the column. Two ear plates on the side of the two horizontally arranged baffles that are close to each other can be detachably connected to a positioning seat.
[0009] An I-shaped connector is provided between the two longitudinally arranged baffles. The two positioning grooves of the connector are provided with sealing strips, and the two adjacent connectors are detachably connected and fixed by connecting columns.
[0010] Furthermore, one of the splicing strips has multiple protrusions fixed to its side, and the other splicing strip has a groove on its side that matches the protrusions.
[0011] Furthermore, a U-shaped positioning frame that is snapped onto the outside of the column is fixed to the side of the horizontal plate. A positioning plate is provided on one side of the positioning frame, and both ends of the positioning frame are provided with bent portions. A screw that passes through the positioning plate is fixed to the bent portion, and a nut is fixed to the end of the screw.
[0012] Furthermore, the positioning seat has a slot that matches the ear plate, and the ear plate is installed on the positioning seat by bolts.
[0013] Furthermore, the connector and the baffle are staggered.
[0014] Furthermore, T-shaped positioning blocks are symmetrically fixed to both ends of the side of the connector, and positioning grooves that are adapted to the positioning blocks are opened at both ends of the connecting column. The connecting column is fixed to the outside of the positioning blocks by bolts.
[0015] Furthermore, a through hole is provided in the middle of the connecting post, and a positioning pin is inserted into the through hole of the connecting post located below.
[0016] Furthermore, the baffle includes a flat plate and an L-shaped plate, and two connecting pieces located between the two longitudinally arranged L-shaped plates are welded together after being chamfered.
[0017] The advantages of this utility model compared with the existing technology are as follows: This utility model can realize the assembly between the upper and lower baffles through the connector, and the baffles can be assembled upward according to the needs. One column, together with the horizontal plate and the positioning seat, can position and fix multiple baffles, improve the stability of baffle assembly, and has strong practicality.

Multiple protruding strips are fixed to the side of one splicing strip 3, and a groove matching the protruding strips is opened on the side of another splicing strip 3.
[0025] By setting the splicing strip 3, the sealing performance of the baffle 2 connection can be improved. When selecting the column 1, the height of the column 1 should be greater than the water depth.
[0026] The baffle 2 has ear plates 4 symmetrically fixed to the middle of its inner side. A horizontal plate 5 is installed on one side of the column 1. Multiple positioning seats 6 are fixed to the side of the horizontal plate 5 away from the column 1. Two ear plates 4 on the side of the two horizontally arranged baffles 2 that are close to each other can be detachably connected to a positioning seat 6. The positioning seat 6 has a slot that matches the ear plate 4. The ear plate 4 is installed on the positioning seat 6 by bolts. A U-shaped positioning frame 10 that is snapped onto the outside of the column 1 is fixed to the side of the horizontal plate 5. A positioning plate 11 is provided on one side of the positioning frame 10. Both ends of the positioning frame 10 have bent parts, and a screw 12 that passes through the positioning plate 11 is fixed to the bent parts. A nut is fixed to the end of the screw 12.
[0027] Two ear plates 4 on the side of the two baffles 2 that are close to each other are connected to a positioning seat 6. Multiple positioning seats 6 are connected to a column 1 through a horizontal plate 5. Thus, the column 1 can fix multiple baffles 2 in a fixed position.
[0028] A connecting member 7 with an I-shaped structure is provided between the two longitudinally arranged baffles 2. The connecting member 7 and the baffles 2 are staggered. Sealing strips 8 are provided in the two positioning grooves of the connecting member 7. The two adjacent connecting members 7 are detachably connected and fixed by connecting posts 9.

The connecting post 9 is fixed to the outside of the positioning blocks 13 by bolts. A through hole is opened in the middle of the connecting post 9. A positioning nail 14 is inserted into the through hole of the lower connecting post 9.
[0029] The connector 7 can be fixed to the bottom of the pit by the positioning nail 14, and the bottom of the connector 7 extends into the soil at the bottom of the pit, which can improve the stability of the bottom of the baffle 2; the two connectors 7 can be connected and fixed by the connecting column 9 in conjunction with the positioning block 13.
[0030] The baffle 2 includes a flat plate and an L-shaped plate, and two connecting pieces 7 located between the two longitudinally arranged L-shaped plates are welded together after being chamfered.
