Description

Technical Field

[0001] This utility model belongs to the field of cofferdam technology and relates to a construction cofferdam device. Background Technology

[0002] A cofferdam is a temporary retaining structure built in water conservancy projects to construct permanent water 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 within the cofferdam. During construction, a cofferdam is typically composed of multiple sets of baffles joined together.

[0003] According to the inspection institute, Chinese patent CN222666848U discloses a cofferdam device for water conservancy engineering construction, including a pile column. Reinforcing mechanisms are provided on both sides of the pile column to improve the overall structural stability. After the pile column is inserted into a designated position, a cover plate is installed in a sliding track on the pile column via a first slider. After installation, the cover plate automatically sinks under its own weight to cover the mud and sand at the insertion point of the pile column, reducing the erosion of the pile column support by flowing water and preventing the pile column from being exposed and causing a decrease in stability. In rivers with relatively rapid flow, counterweight rocks can be placed on the inner wall of the top frame of the cover plate to further improve the stability of the pile column. By creating a hollow groove on the water-retaining side of the pile column, when the water flow impacts the pile column, it will preferentially squeeze the elastic plate, reducing the potential energy of the water and minimizing damage to the pile column through the deformation of the elastic plate. However, in the above patent, the first and second sliders are only slidably connected to the sliding track without a locking structure during use. When impacted by water flow, ground settlement, or external force collisions, the slider is prone to shift along the slideway, causing the reinforcement position of the cover plate and tie rod to deviate, weakening the support effect on the pile. At the same time, the lower part of the cover plate of the reinforcement mechanism does not have a structure connecting it to the riverbed, and the bottom of the pile only has a wedge plug, lacking a gripping structure, making it easy to loosen and shift under repeated impacts from the river water.

[0004] Therefore, this utility model provides a construction cofferdam device to solve the above problems. Utility Model Content

[0005] In view of the problems existing in the prior art, this utility model discloses a construction cofferdam device. The technical solution adopted is as follows: a cofferdam baffle is provided, the left half of the cofferdam baffle has a set platform on the front and rear side walls respectively, the right side wall of the cofferdam baffle is fixedly provided with a slot, the lower part of the cofferdam baffle is uniformly arrayed with ground anchors, the upper end of the right half of the front side wall of the cofferdam baffle is fixedly provided with a screw sleeve, an adjusting screw is screwed into the screw sleeve, the left and right sides of the front side wall of the baffle at the lower part of the screw sleeve are fixedly provided with L-shaped slots, and a reinforcing support component is movably inserted between the left and right L-shaped slots.

[0006] As a preferred embodiment of this utility model, a rectangular groove is formed at the top of the cofferdam baffle; by forming a rectangular groove, the weight of the cofferdam baffle is reduced and its portability is improved.

[0007] As a preferred embodiment of this utility model, through holes are respectively opened at the middle part of the upper edge of the sink and the middle part of the upper edge of the slot, and fixing bolts are screwed into the through holes on the front and back of the right side.

[0008] In a preferred embodiment of this utility model, the sinking platform matches the slot; the left and right adjacent cofferdam baffles are connected by the corresponding sinking platform and slot.

[0009] As a preferred embodiment of this utility model, the circumferential sidewall of the ground anchor has a number of upwardly inclined barbs evenly arranged from top to bottom; by opening the barbs, it is easier to hammer the ground anchor into the riverbed, thereby increasing the friction between it and the riverbed and preventing the cofferdam baffle from loosening after being impacted by the river water.

[0010] As a preferred embodiment of this utility model, the reinforcing support assembly includes a T-shaped slider that is slidably inserted between the left and right L-shaped slots. A triangular reinforcing rib is fixedly connected to the front side wall of the T-shaped slider, and a support plate is fixedly connected to the lower part of the triangular reinforcing rib. Conical spikes are evenly arrayed on the lower part of the support plate. By using the reinforcing support assembly, it is convenient to reinforce and support the backwater side of the cofferdam baffle, thereby improving its stability during use.

[0011] The beneficial effects of this utility model are as follows: By quickly connecting the left and right adjacent cofferdam baffles together through the sinking platform and slot, pressure is applied to the top of the cofferdam baffles, and the bottom ground anchor is hammered into the riverbed. Under the action of the barbs, the stability after insertion into the riverbed is further improved. At the same time, the tops of the left and right adjacent cofferdam baffles are connected by fixing bolts, which, together with the lower ground anchor, improves the stability between adjacent cofferdam baffles. In addition, by adjusting the screw rod, the vertical relative position between the reinforcement support component and the cofferdam baffle can be adjusted according to the unevenness of the riverbed. This can effectively limit the position of the reinforcement support component, improve its flexibility, and improve the stability of the support. Attached Figure Description

[0018] like Figures 1 to 4 As shown, the construction cofferdam device of this utility model adopts the following technical solution: It includes a cofferdam baffle 1. The left half of the cofferdam baffle 1 has sinkholes 11 on its front and rear side walls. The right side wall of the cofferdam baffle 1 has a fixed slot 12, with the sinkholes 11 matching the slots 12. Ground anchors 2 are evenly arranged in an array at the lower part of the cofferdam baffle 1. The circumferential side walls of the ground anchors 2 have a plurality of upwardly inclined barbs 21 evenly arranged from top to bottom. A screw rod sleeve 13 is fixedly installed at the upper end of the right half of the front side wall of the cofferdam baffle 1. An adjusting screw rod 3 is screwed into the screw rod sleeve 13. The left and right sides of the front side wall of the baffle at the lower part of the screw rod sleeve 13 are relatively fixedly arranged... An L-shaped slot 14 is provided. A rectangular sinkhole 15 is opened downward from the top of the cofferdam baffle 1. Through holes 16 are opened at the middle part of the upper edge of the sinkhole 11 and the middle part of the upper edge of the slot 12. Fixing bolts 17 are screwed into the through holes 16 on the right side. A reinforcing support assembly 4 is movably inserted between the left and right L-shaped slots 14. The reinforcing support assembly 4 includes a T-shaped slider 41 that is slidably inserted between the left and right L-shaped slots 14. A triangular reinforcing rib 42 is fixedly connected to the front side wall of the T-shaped slider 41. A support plate 43 is fixedly connected to the lower part of the triangular reinforcing rib 42.

[0019] The working principle of this utility model is as follows: In use, the adjacent left and right cofferdam baffles 1 are inserted into the corresponding slots 12 through the corresponding sinkers 11, and the T-shaped sliders 41 of the corresponding reinforcing support components 4 are slidably inserted into the left and right L-shaped slots 14 from the bottom, applying downward pressure to the top of the cofferdam baffles 11, forcing the bottom anchors 2 to drill into the bottom of the riverbed. The fixing bolts 17 are inserted into the corresponding through holes 16 to achieve a tight connection between the two adjacent cofferdam baffles 1. Then, according to the uneven terrain of the riverbed on the back side of the cofferdam baffles 1, the adjusting screw 3 is rotated, and the bottom of the adjusting screw 3 is pressed downward to tighten the reinforcing support components 4, so that the cone 44 at the bottom of the support plate 43 is inserted into the riverbed, forming a stable support and reinforcement effect. Other cofferdam baffles 1 are spliced ​​and installed one by one in the same way to achieve the effect of a cofferdam.
