Description

Technical Field

[0001] This utility model relates to the field of cofferdam device technology, and in particular to a cofferdam device for water conservancy construction. Background Technology

[0002] A cofferdam is a temporary water conservancy facility or retaining structure built in the construction of water conservancy projects to prevent water and soil from entering the construction site of the structure, so as to facilitate drainage, excavation of foundation pits, and construction of structures. It is generally used in hydraulic engineering structures.

[0003] Currently, existing hydraulic construction cofferdam devices typically consist of multiple interconnected fixed templates. However, these vertical panels have limited compressive strength and lack external protective devices. This allows impurities such as mud and sand in the water to impact the cofferdam, causing deformation and affecting its lifespan. Therefore, a new hydraulic construction cofferdam device is needed to address these issues. Utility Model Content

[0004] The purpose of this invention is to solve the problems mentioned in the background section.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A cofferdam device for hydraulic construction includes a cofferdam assembly. The cofferdam assembly includes four panels arranged in a U-shape. Adjacent panels are fixed at their corners by reinforcement members. Reinforcing members are provided inside the panels, and reinforcing plates are provided on the outer sides of the panels at positions that mate with the reinforcing members.

[0007] Preferably, the reinforcing member includes a frame that is fitted to the inner wall of the enclosure. The outer side of the reinforcing plate is fixed by passing through the enclosure and the frame sequentially through the through nail shaft. By passing through the reinforcing plate, the enclosure and the frame through the through nail shaft, multiple layers can be connected in series to form a whole. The frame and the reinforcing plate work together to reinforce the enclosure from the inside and outside, further improving the stability of the enclosure.

[0008] Preferably, the enclosure panel has an S-shaped multi-segment bending structure design, with the sides of two adjacent enclosure panels fitting together. Through the multi-segment bending structure design of the enclosure panel, the overall compressive strength of the enclosure panel can be reduced to a certain extent.

[0009] Preferably, the inner wall corner of the frame is provided with a plug in the slot, and the outside of the plug is connected to a corner plate. The plug can be inserted into the slot of the frame from top to bottom, thereby quickly completing the assembly of the corner plate.

[0010] Preferably, the corner plate has threaded nails inserted through through holes on its surface, and the threaded nails are inserted into the frame through threaded holes. The corner plate fits against the inner wall of the frame, and the installation of the corner plate can be reinforced by the threaded nails, thereby reinforcing the corners of the frame.

[0011] Preferably, a column is provided at the center of the sides of the upper and lower frames, and the upper and lower ends of the column are inserted into the slots of the frame through rectangular blocks. The column is installed between the two frames to reinforce the frame.

[0012] Preferably, the reinforcing component includes a reinforcing plate, which wraps around the outer corner of the enclosure. A insert plate is inserted into the side of the reinforcing plate through a slot, and a buckle plate is connected to the outside of the insert plate. The buckle plate is inserted into the surface of the enclosure through a bending groove. A long screw shaft is inserted into the side of the reinforcing plate through a through hole, and the end of the long screw shaft is inserted into the insert plate through a threaded hole. After the enclosure is assembled, the reinforcing plate can be fastened to the corner of the enclosure to reinforce the corner of the enclosure.

[0013] This utility model has at least the following beneficial effects:

[0014] 1. By setting up cofferdam components, the compressive strength is improved. Compared with the traditional structure, this device uses four bent cofferdam panels to enclose and connect, which can effectively improve the compressive strength and prevent local deformation when impurities such as mud and sand in the water impact the cofferdam panels, thus ensuring the strength of the cofferdam panels. The joint edges of two adjacent cofferdam panels are reinforced with fasteners, and the buckle plates are connected to the reinforcing plates by plugging, thereby achieving reinforcement at the corners of the cofferdam panels.

[0015] 2. By setting reinforcement components, the inner wall of the enclosure is reinforced. In this device, two frames are fixed to the inner wall of the enclosure by through nail shafts. Corner plates are installed at the corners of the frames by plugging. The cooperation between the frames and the corner plates can reinforce the sides and corners of the enclosure, further enhancing the compressive strength of the enclosure and ensuring its service life.

[0022] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0023] Reference Figure 1-4 A cofferdam device for water conservancy construction includes a cofferdam component 1, which includes four cofferdam panels 11 arranged in a U-shape. The corners of two adjacent cofferdam panels 11 are fixed by a reinforcement member 12. A reinforcing member 2 is provided inside the cofferdam panel 11, and a reinforcing plate 3 is provided on the outer side of the cofferdam panel 11 at the position where it is adapted to the reinforcing member 2.

[0024] The reinforcing component 2 includes a frame 21, which is attached to the inner wall of the enclosure 11. The outer side of the reinforcing plate 3 is fixed to the frame 21 by passing through the enclosure 11 in sequence via a through nail shaft 4.

[0025] The enclosure panel 11 has an S-shaped multi-segment bending structure design, with the sides of two adjacent enclosure panels 11 fitting together.

[0026] An insert block 23 is embedded in a slot at the corner of the inner wall of the frame 21, and a corner plate 22 is connected to the outside of the insert block 23.

[0027] The corner plate 22 has a threaded nail 24 inserted through a through hole on its surface, and the threaded nail 24 is inserted into the frame 21 through a threaded hole, so that the corner plate 22 fits against the inner wall of the frame 21.

[0028] A column 25 is provided at the center of the sides of the upper and lower frames 21, and the upper and lower ends of the column 25 are inserted into the slots of the frame 21 through rectangular blocks.

[0029] The reinforcement component 12 includes a reinforcement plate 121, which wraps around the outer corner of the enclosure 11. A plug plate 122 is inserted into the side of the reinforcement plate 121 through a slot, and a buckle plate 123 is connected to the outside of the plug plate 122. The buckle plate 123 is inserted into the surface of the enclosure 11 through a bending groove. A long rod screw 124 is inserted into the side of the reinforcement plate 121 through a through hole, and the end of the long rod screw 124 is inserted into the plug plate 122 through a threaded hole.

[0030] The reinforcing plate 3, the surrounding plate 11, and the frame 21 can be connected in series by the through nail shaft 4 to form a whole. The frame 21 and the reinforcing plate 3 can reinforce the surrounding plate 11 from the inside and outside, further improving the stability of the surrounding plate 11. The multi-segment bending structure design of the surrounding plate 11 can reduce the overall compressive strength of the surrounding plate 11 to a certain extent. At the same time, the bending groove of the surrounding plate 11 can reduce the impact area of ​​mud and sand, thereby reducing the impact force when local pressure is applied. When the diagonal plate 22 is installed, the insert 23 can be inserted into the slot of the frame 21 from top to bottom, thereby quickly completing the assembly of the diagonal plate 22. When the diagonal plate 22 is attached to the inner wall of the frame 21, the installation of the diagonal plate 22 can be reinforced by the threaded nail 24, thereby reinforcing the corners of the frame 21.

[0031] The column rod 25 is installed between the two frames 21 at the foot of the mountain to reinforce the frames 21, so that the upper and lower frames 21 can be connected to each other and effectively prevent local deformation of the enclosure 11 under pressure. After the enclosure 11 is assembled, the reinforcing plate 121 can be fastened to the corner of the enclosure 11 to reinforce the corner of the enclosure 11. At the same time, the insert plate 122 is inserted into the slot on the inner side of the reinforcing plate 121, so that the fastening plate 123 is embedded in the bending groove of the enclosure 11, thereby completing the assembly and reinforcement of the two enclosures 11. The long rod screw 124 passes through the reinforcing plate 121 and is inserted into the insert plate 122 to reinforce the connection between the insert plate 122 and the reinforcing plate 121.

[0032] Working principle: According to the appendix Figure 3 With appendix Figure 4 As shown, during use, the four enclosure panels 11 can be formed into an enclosing structure, so that the reinforcing plate 121 is fastened at the corner of two adjacent enclosure panels 11, and the insert plate 122 is inserted into the slot of the reinforcing plate 121 from top to bottom, thus completing the connection of the fastening plate 123. At this time, the fastening plate 123 can be inserted into the bending groove of the enclosure panel 11, thereby reinforcing the enclosure panel 11.

[0033] Secondly, according to the appendix Figure 1 With appendix Figure 2As shown, the frame 21 is installed inside the enclosure 11, and the reinforcing plate 3, enclosure 11 and frame 21 are penetrated by the through nail shaft 4, so that the three are integrated. The corner plate 22 is installed at the corner of the inner wall of the frame 21, and the insert 23 is snapped into the frame 21 through the slot. The threaded nail 24 can penetrate the corner plate 22 and be inserted into the frame 21, thereby reinforcing the corner of the frame 21.

[0034] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely principles of this utility model.
