Description

Technical Field

[0001] This application relates to the field of cofferdam technology, specifically a new type of cofferdam device for water conservancy construction. Background Technology

[0002] 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.

[0003] When using existing cofferdams, steel plates need to be installed on the inner side of the cofferdam for support and fixation. However, the length of the steel plates is inconvenient to adjust. If the steel plates are too long, they are inconvenient to install. If the steel plates are too short, the support is not stable enough, thus affecting the stability of the cofferdam.

[0004] Therefore, there is an urgent need for a new type of cofferdam device for water conservancy construction to solve the problem that it is not convenient and stable to install steel plates on cofferdams. Utility Model Content

[0005] To address the shortcomings of existing technologies, this application provides a novel cofferdam device for water conservancy construction, which has the advantage of improving the stability of the cofferdam and solves the problem that it is not convenient and stable to install steel plates on the cofferdam.

[0006] To achieve the above objectives, this application provides the following technical solution: a novel cofferdam device for water conservancy construction, comprising an outer baffle, an inner baffle, a concrete partition, and a support column. Several sets of the outer baffles are spliced ​​together to form an outer plate, and several sets of the inner baffles are spliced ​​together to form an inner plate. The support column is cast inside the concrete partition and extends out of the bottom of the concrete partition. The concrete partition is cast in a groove formed between the outer baffle and the inner baffle. A support mechanism is provided on the inner side of the inner baffle, and a fixing mechanism is provided on the outer side of the outer baffle.

[0007] The support mechanism includes a fixed plate, a support base, a threaded sleeve, and a support rod. The fixed plate is fixedly connected to the inner side of the inner baffle by screws. The support base is fixedly connected to the inner side of the fixed plate by screws. One end of the threaded sleeve is rotatably connected to the inner side of the support base. The other end of the threaded sleeve is threadedly connected to one end of the support rod. The other end of the support rod is welded to the inner side of another set of support bases.

[0008] By adjusting the elongation of the threaded sleeve, the threaded sleeve and the support rod support the fixed plate and the support seat, allowing the fixed plate and the support seat to be stably supported on the inner side of the inner baffle. The support of the four sets of support rods and threaded sleeves makes the inner side of the cofferdam more stable, improves the strength of the cofferdam, and makes the water conservancy construction workers safer on the inner side of the cofferdam.

[0009] Preferably, a baffle is welded to the outer surface of the support rod, and a plurality of bolts are installed on the top of the threaded sleeve, the bolts passing through the threaded sleeve and extending into the interior of the support rod.

[0010] Preferably, the support rod consists of two parts: a smooth rod body and a threaded rod body.

[0011] Preferably, the outer side of the fixing plate is an arc-shaped surface that matches the inner arc-shaped surface of the inner baffle.

[0012] Preferably, the fixing mechanism includes a fixing plate, a second support base, a plug rod, and a limiting plate. The fixing plate is welded to the outside of the outer side of the outer baffle. The second support base is fixedly connected to the outside of the fixing plate by screws. The plug rod passes through the inside of the second support base. The three sets of limiting plates are welded to the outside of the bottom of the plug rod and are evenly distributed.

[0013] Preferably, a plurality of bolts are installed on the outer side of the support base two, and the bolts two penetrate the support base two and extend into the interior of the insert rod.

[0014] Preferably, the inner side of the fixing plate is an arc-shaped surface that matches the arc-shaped surface of the outer side of the outer baffle.

[0015] In summary, this application includes at least one of the following beneficial effects:

[0016] 1. This new type of cofferdam device for water conservancy construction involves installing outer and inner baffles on the outside during installation. A concrete interlayer is poured between the outer and inner baffles, and support columns are inserted into the ground to support the cofferdam. Simultaneously, by rotating the support rods, the threaded sleeves extend, allowing the fixing plate and support seat to stably support the inner side of the inner baffle. The support of four sets of support rods and threaded sleeves makes the inner side of the cofferdam more stable, improves the strength of the cofferdam, and makes it safer for water conservancy construction workers inside the cofferdam.

[0017] 2. In this new type of cofferdam device for water conservancy construction, during the installation of the outer baffle, the insert rod is pushed downward by the pile driver, so that the insert rod can drive the limiting plate to be inserted into the ground. The outer baffle is supported by the support seat and the fixing plate, making the outer baffle more stable, thereby improving the stability of the cofferdam. Attached Figure Description

[0023] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0024] Please see Figure 1-4 A novel cofferdam device for water conservancy construction includes an outer baffle 1, an inner baffle 2, a concrete partition 3, and a support column 4. Several sets of outer baffles 1 are spliced ​​together to form an outer plate, and several sets of inner baffles 2 are spliced ​​together to form an inner plate. The outer baffles 1 and inner baffles 2 are installed underground to form two partitions, an inner and an outer one. The concrete partition 3 is poured between the outer baffles 1 and the inner baffles 2 to improve the waterproofness of the cofferdam. At the same time, the support column 4 is inserted into the ground to support the cofferdam. The support column 4 is poured inside the concrete partition 3 and extends out of the bottom of the concrete partition 3. The concrete partition 3 is poured into the groove formed between the outer baffles 1 and the inner baffles 2. A support mechanism is provided on the inner side of the inner baffle 2, and a fixing mechanism is provided on the outer side of the outer baffle 1.

[0025] Specifically, the support mechanism includes a fixed plate 111, a support base 112, a threaded sleeve 113, and a support rod 114. The fixed plate 111 is fixedly connected to the inner side of the inner baffle 2 by screws. The support base 112 is fixedly connected to the inner side of the fixed plate 111 by screws. The outer side of the fixed plate 111 is an arc-shaped surface that matches the arc-shaped surface of the inner side of the inner baffle 2. One end of the threaded sleeve 113 is rotatably connected to the inner side of the support base 112. The other end of the threaded sleeve 113 is threadedly connected to one end of the support rod 114. The other end of the support rod 114 is welded to the inner side of another set of support bases 112. A baffle 116 is welded to the outer surface of the support rod 114. The support rod 114 consists of two parts: a smooth rod body and a threaded rod body. Several sets of bolts 115 are installed on the top of the threaded sleeve 113. The bolts 115 penetrate the threaded sleeve 113 and extend into the interior of the support rod 114.

[0026] With the above technical solution, when the cofferdam is installed, by rotating the support rod 114, the support rod 114 drives the threaded sleeve 113 to extend. When the support rod 114 extends to a suitable length, the workers use bolts 115 to fix the support rod 114. With the support of the support rod 114 and the threaded sleeve 113, the fixing plate 111 and the support seat 112 are stably supported on the inner side of the inner baffle 2. The support of the four sets of support rods 114 and threaded sleeves 113 makes the inner side of the cofferdam more stable, improves the strength of the cofferdam, and makes the workers in water conservancy construction safer on the inner side of the cofferdam. The baffle plate 116 can limit the position of the support rod 114.

[0027] Specifically, the fixing mechanism includes a fixing plate 211, a second support base 212, a plug rod 213, and a limiting plate 214. The fixing plate 211 is welded to the outside of the outer baffle 1. The second support base 212 is fixedly connected to the outside of the fixing plate 211 by screws. The inner side of the fixing plate 211 is an arc-shaped surface that matches the arc-shaped surface of the outer side of the outer baffle 1. The plug rod 213 passes through the inner side of the second support base 212. Three sets of limiting plates 214 are welded to the bottom outer side of the plug rod 213 and are evenly distributed. Several sets of bolts 215 are installed on the outer side of the second support base 212. The bolts 215 pass through the second support base 212 and extend into the inside of the plug rod 213.

[0028] With the above technical solution, during the installation of the outer baffle 1, the insert rod 213 is pushed downward by the pile driver, so that the insert rod 213 can drive the limiting plate 214 to be inserted into the ground. When the insert rod 213 moves to the appropriate position, the workers use bolt 215 to fix the position of the insert rod 213. The outer baffle 1 is supported by the support seat 212 and the fixing plate 211, making the outer baffle 1 more stable, thereby improving the stability of the cofferdam.

[0029] In use, by adjusting the extension length of the threaded sleeve 113, the threaded sleeve 113 and the support rod 114 support the fixed plate 111 and the support seat 112, so that the fixed plate 111 and the support seat 112 are stably supported to the inside of the inner baffle 2. The support of the four sets of support rods 114 and threaded sleeve 113 makes the inner side of the cofferdam more stable, improves the strength of the cofferdam, and makes the water conservancy construction workers safer inside the cofferdam.
