Description

Technical Field

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

[0002] With the rapid development of society and economy, water conservancy projects have become one of the most important projects for my country's economic development. Water conservancy projects are engineering projects built to control and regulate surface water and groundwater in nature to achieve the purpose of eliminating harm and promoting benefits. Cofferdam devices refer to temporary retaining structures built in water conservancy projects to construct permanent water conservancy facilities. The function of cofferdam devices is to prevent water and soil from entering the construction site of the building so as to facilitate drainage, excavation of foundation pits, and construction of buildings. They are generally used in hydraulic structures. Except when used as part of a formal building, cofferdam devices are generally dismantled after use. The height of the cofferdam device is higher than the highest water level that may occur during the construction period. In the existing technology, cofferdams are usually wall structures formed by stacking sandbags or boards. Although they can effectively block water flow, when the water flow suddenly increases, due to the influence of the stacked connection of the cofferdam, it will be subject to greater impact force and may tilt or collapse, affecting the construction progress.

[0003] For example, a water conservancy construction cofferdam device disclosed in Chinese patent literature (publication number: CN219470983U) uses a reinforced component. When the cofferdam is blocking water, the cone-shaped body at the lower end of the plug is first inserted into the ground. Then, the rotating rod is rotated, and one end of the rotating rod squeezes the T-shaped block. Therefore, the inclined plate has a horizontal force. However, because the T-shaped block and the T-shaped groove are matched and matched, the inclined plate squeezes the outside of the fixed frame, thereby providing a supporting force for the cofferdam and stabilizing the cofferdam, preventing the entire cofferdam from collapsing.

[0004] However, it only provides support for the enclosure, and the connection between the reinforcement component and the ground is only fixed by inserting a cone. The connection stability with the ground is low. When the water flow impact force is large, the single cone is easy to loosen from the ground, which can easily cause the reinforcement component to detach from the ground and thus cause the enclosure to collapse.

[0005] Therefore, we propose a cofferdam device for hydraulic construction. Utility Model Content

[0006] The purpose of this invention is to address the shortcomings of existing technologies. Currently, the outside of the fixed frame is compressed by an inclined plate to provide support for the enclosure. However, the connection between the reinforcement component and the ground is only achieved by inserting a cone. When the water flow impact force is large, the single cone is prone to loosening from the ground, which can easily cause the reinforcement component to detach from the ground and lead to the collapse of the enclosure.

[0007] To achieve the above objectives, the present invention adopts the following technical solution:

[0008] A cofferdam device for hydraulic construction includes a base plate. Connectors arranged in a rectangular array are fixedly connected to the upper surface of the base plate. A surrounding plate is movably inserted into the inner wall of each adjacent connector. A connecting plug is fixedly connected to one side surface of the surrounding plate. A limiting block is movably inserted into the inner wall of the connecting plug. A support rod is fixedly connected to one side surface of the limiting block. A reinforcing block is fixedly connected to one end of the support rod. A tapered insert is fixedly connected to the lower surface of the reinforcing block in a symmetrical arrangement.

[0009] The inner wall of the reinforcement block is provided with a ground reinforcement device, and the ground reinforcement device includes a reinforcement sleeve, the outer surface of which is movably inserted into the inner wall of the reinforcement block.

[0010] Preferably, a tapered insert is fixedly connected to the lower end of the reinforcing sleeve, and an annular striking block is fixedly connected to the upper surface of the reinforcing sleeve, with the lower surface of the annular striking block in contact with the upper surface of the reinforcing block.

[0011] Preferably, a lifting rod is fixedly connected to the inner wall of the annular striking block, and through grooves distributed in an annular array are opened on the outer surface of the reinforcing sleeve. An installation plate is fixedly sleeved on the inner wall of the reinforcing sleeve.

[0012] Preferably, a lead screw is mounted on the inner wall of the mounting plate via a bearing. One end of the lead screw is fixedly connected to a drive turntable, and the outer surface of the other end of the lead screw is threadedly connected to a threaded sleeve. The outer surface of the threaded sleeve is fixedly connected to symmetrically distributed guide blocks.

[0013] Preferably, the inner wall of the guide block is movably sleeved with a guide rod, one end of each of the two guide rods is fixedly connected to the lower surface of the mounting plate, the lower end of the threaded sleeve is fixedly connected with a conical extrusion block, and the inner wall of the reinforcing sleeve is fixedly connected with a fixed seat arranged in a ring array.

[0014] Preferably, a reinforcing rod is movably sleeved on the inner wall of the fixing seat, one end of the reinforcing rod extends into the interior of the through groove, and the other end of the reinforcing rod is fixedly connected to an extrusion ball, the outer surfaces of the plurality of extrusion balls being in contact with the outer surface of the conical extrusion block.

[0015] Preferably, a return spring is movably sleeved on the outer surface of the reinforcing rod, one end of the return spring is fixedly connected to one side surface of the fixed seat, and the other end of the return spring is fixedly connected to the outer surface of the extruded ball.

[0016] Compared with the prior art, the beneficial effects of this utility model are:

[0017] In this utility model, the ground reinforcement device achieves the effect of moving the conical extrusion block in conjunction with the extrusion ball to drive the reinforcing rod to be inserted horizontally into the ground. This, combined with the vertical insertion of the conical insert and the reinforcing sleeve, generates a crisscrossing gripping force with the ground. This avoids the problem of a single vertical insertion easily loosening and detaching from the ground when there is a large impact from the water flow, thereby improving the stability of the support panel.

[0028] Example 1

[0029] like Figure 1-5 As shown, this utility model provides a technical solution: a cofferdam device for water conservancy construction, including a base plate 1, with connectors 2 arranged in a rectangular array fixedly connected to the upper surface of the base plate 1, and a surrounding plate 3 movably inserted into the inner wall of each adjacent connector 2, and a sealing gasket provided between the connector 2 and the surrounding plate 3 for sealing and preventing water seepage, with a connecting plug 4 fixedly connected to one side surface of the surrounding plate 3, and a limiting block 5 movably inserted into the inner wall of the connecting plug 4, with a support rod 6 fixedly connected to one side surface of the limiting block 5, and a reinforcing block 7 fixedly connected to one end of the support rod 6, and tapered inserts 8 arranged symmetrically connected to the lower surface of the reinforcing block 7;

[0030] The inner wall of the reinforcing block 7 is provided with a ground reinforcement device, and the ground reinforcement device includes a reinforcing sleeve 9, the outer surface of which is movably inserted into the inner wall of the reinforcing block 7.

[0031] Example 2

[0032] like Figure 1-5As shown, this utility model provides a technical solution: a conical insert 91 is fixedly connected to the lower end of the reinforcing sleeve 9, and an annular striking block 92 is fixedly connected to the upper surface of the reinforcing sleeve 9. The lower surface of the annular striking block 92 contacts the upper surface of the reinforcing block 7. The annular striking block 92 facilitates striking by external hammers and striking equipment, thereby facilitating the insertion of the reinforcing sleeve 9 into the ground for fixation in conjunction with the conical insert 91.

[0033] The inner wall of the annular striking block 92 is fixedly connected to a lifting rod 93. The outer surface of the reinforcing sleeve 9 is provided with through grooves 94 arranged in an annular array. The inner wall of the reinforcing sleeve 9 is fixedly fitted with an installation plate 95. The lifting rod 93 serves to facilitate lifting and disassembly in conjunction with an external crane.

[0034] A lead screw 96 is mounted on the inner wall of the mounting plate 95 via a bearing. One end of the lead screw 96 is fixedly connected to a drive turntable 97, and the other end of the lead screw 96 is threadedly connected to a threaded sleeve 98. The outer surface of the threaded sleeve 98 is fixedly connected to symmetrically distributed guide blocks 99. The drive turntable 97 serves to facilitate the rotation of the lead screw 96.

[0035] The inner wall of the guide block 99 is movably fitted with guide rods 910. One end of each guide rod 910 is fixedly connected to the lower surface of the mounting plate 95. The lower end of the threaded sleeve 98 is fixedly connected with a conical extrusion block 911. The inner wall of the reinforcing sleeve 9 is fixedly connected with fixed seats 912 arranged in a ring array. The cooperation between the guide block 99 and the guide rods 910 serves to limit the rotation of the threaded sleeve 98 and guide its lifting and lowering.

[0036] A reinforcing rod 913 is movably sleeved on the inner wall of the fixed base 912. One end of the reinforcing rod 913 extends into the interior of the through groove 94, and the other end of the reinforcing rod 913 is fixedly connected to a compression ball 914. The outer surfaces of the multiple compression balls 914 are in contact with the outer surface of the conical compression block 911. The reinforcing rod 913 is inserted laterally to the outside through the through groove 94, thereby enhancing the grip.

[0037] A return spring 915 is movably sleeved on the outer surface of the reinforcing rod 913. One end of the return spring 915 is fixedly connected to one side surface of the fixed seat 912, and the other end of the return spring 915 is fixedly connected to the outer surface of the extrusion ball 914. The return spring force of the return spring 915, through the cooperation of the fixed seat 912, drives the reinforcing rod 913 to return and retract.

[0038] The ground reinforcement device enables the conical extrusion block 911 to move and extrude the extrusion ball 914 to drive the reinforcing rod 913 to be inserted horizontally into the ground. This, combined with the vertical insertion of the conical insertion block 91 and the reinforcing sleeve 9, creates a crisscrossing gripping force with the ground. This prevents the single vertical insertion from easily loosening and detaching from the ground when the water flow impact is large, thereby improving the stability of the support for the enclosure panel 3.

[0039] The working process of this utility model:

[0040] Step 1: Insert the limiting block 5 into the ground via the connecting plug 4. Move the limiting block 5 downwards to allow it to move and drive the tapered plug 8 below the reinforcing block 7 through the support rod 6 for initial limiting and fixing. Then, insert the reinforcing sleeve 9 into the interior of the reinforcing block 7 via the tapered plug 91. During insertion, the ring-shaped hammer can be used to strike the ring-shaped hammer block 92, which facilitates the insertion of the reinforcing sleeve 9 into the ground through the cooperation of the tapered plug block 91. Stop striking when the ring-shaped hammer block 92 contacts the top of the reinforcing block 7.

[0041] Step two: At this time, the drive turntable 97 drives the lead screw 96 to rotate clockwise. The rotation of the lead screw 96 drives the threaded sleeve 98 to move downward through the guide rod 910 and the guide block 99. The downward movement of the threaded sleeve 98 drives the conical extrusion block 911 to move downward and extrude the extrusion ball 914. After being extruded, the extrusion ball 914 extrudes and contracts the return spring 915. Through the guidance of the fixed seat 912, one end of the reinforcing rod 913 extends out of the through groove 94 and inserts laterally into the ground. In this way, the crisscrossing gripping force improves the support stability of the enclosure 3.

[0042] Step 3: During dismantling, the drive turntable 97 drives the lead screw 96 to rotate counterclockwise. The counterclockwise rotation of the lead screw 96 drives the conical extrusion block 911 to rise and reset through the threaded sleeve 98. At this time, the reset spring 915, through the extrusion ball 914, drives the reinforcing rod 913 to retract and move, thereby causing the reinforcing rod 913 to retract and detach from the inserted ground. After detachment, the external crane equipment hooks the lifting rod 93 to move upward, thereby causing the reinforcing sleeve 9 and the conical insert 91 to detach from the inserted ground.

[0043] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
