[0002] Construction on water is easily affected by water level fluctuations. Traditional construction methods are chosen when the water level is low and the work surface is exposed. However, construction becomes impossible when the water level rises, limiting the working time. Alternatively, cofferdams can be built around the structure, but this involves large-scale projects, significant impacts on the surrounding natural environment, and high costs. Utility Model Content

[0003] In response to the aforementioned technical problems of being unable to construct after the water level rises, the large scale of cofferdam construction projects, the impact on the natural environment, and the high cost, this utility model provides a pile foundation micro-cofferdam cover.

[0004] This utility model provides a miniature cofferdam cover for a pile foundation. The miniature cofferdam cover for a pile foundation includes: a pile foundation, an outer shell including at least two outer shell parts, the outer shell parts being detachably connected around the pile foundation, and a water-stop membrane in the shape of a strip, which is arranged around the pile foundation with its bottom end lower than the bottom of the outer shell. The outer shell parts are provided with a fixing clip, which includes a screw rod and a fixing end movably connected to the screw rod. The fixing end moves closer to the pile foundation under the push of the screw rod. The edge of the outer shell parts is provided with a connecting hole and a water-stop strip.

[0005] The micro-cofferdam cover for pile foundations provided by this utility model may also have the following feature: the outer shell surrounds the pile foundation to form a cylinder or cuboid.

[0006] The micro cofferdam cover for pile foundations provided by this utility model may also have the following features: the outer shell includes a base plate and a surrounding plate, the surrounding plate is arranged around the outer edge of the base plate and forms an upward-facing working space.

[0007] The micro cofferdam cover for pile foundation provided by this utility model may also have the following features: ribs are provided on the inner and outer surfaces of the outer shell, and the fixing clip is provided on the inner rib of the outer shell near one end of the pile foundation.

[0012] The beneficial effects of this utility model are as follows:

[0013] This utility model discloses a micro-cofferdam cover for pile foundations, comprising a pile foundation, an outer shell, and a water-stop membrane. The outer shell includes at least two outer shell segments, which are detachably connected around the pile foundation. The water-stop membrane, in the form of a strip, is arranged around the pile foundation, with its bottom end positioned lower than the bottom of the outer shell. A fixing clip is provided on the outer shell segment, comprising a threaded rod and a fixing end. The fixing end is movably connected to the threaded rod, and the fixing segment moves closer to the pile foundation under the push of the threaded rod. Additionally, connection holes and water-stop strips are provided at the edges of the outer shell segment. Based on this micro-cofferdam cover for pile foundations, the outer shell segments surround the pile foundation, isolating it from water in the surrounding environment and providing space for water-based operations. Furthermore, a water-stop membrane is provided at the bottom of the outer shell, which isolates water at the contact point between the outer shell and the pile foundation, preventing external water from flowing into the outer shell from the connection point, thereby ensuring the dryness and safety of the internal space of the outer shell. Moreover, the multi-segment connection method of the outer shell segments facilitates the transportation and installation of the outer shell. Furthermore, the shell structure, which can be completed in two halves, involves fewer structural components, making it easy to assemble and saving on the cost of the cofferdam.

[0014] In addition, the outer casing includes a base plate and a surrounding plate. The surrounding plate is arranged around the outer edge of the base plate to form an upward-facing working space. This working space can provide working space for the water-based operations of the pile foundation, as well as support for the auxiliary structures of the pile foundation.

[0015] In addition, ribs are provided on both the inner and outer surfaces of the outer casing to enhance its structural strength. A fixing clamp is located on the inner rib of the outer casing near the pile foundation, allowing the fixing end to clamp the pile foundation by pushing it.

[0016] Furthermore, the upper end of the waterstop extends upwards to above the bottom inner side of the outer casing. When the upper end of the waterstop extends above the bottom inner side of the outer casing, the fixing end can simultaneously clamp the waterstop and the pile foundation. Additionally, the lower end of the waterstop is fixed by a clamping plate, which is connected to the bottom of the outer casing. Extending the waterstop into the outer casing further prevents water from flowing into the outer casing from the gap between the pile foundation and the outer casing, ensuring a dry environment within the working space.

[0022] To make the technical problems solved, technical solutions, and beneficial effects 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] In this embodiment, the micro-cofferdam cover for pile foundations is applied to pile foundations used in water operations. By encircling the pile foundation, a micro-cofferdam is formed, providing a working environment for water operations.

[0024] like Figures 1-5 As shown, the micro-cofferdam cover for the pile foundation includes a pile foundation 10, an outer shell 20, and a waterstop membrane 30.

[0025] The installation of pile foundation 10 is underway in the water area.

[0026] The outer casing 20 includes at least two outer casing segments 21. The outer casing segments 21 are detachably connected. Each outer casing segment 21 includes a base plate 211 and a surrounding plate 212. The lower end of the surrounding plate 212 surrounds the outer edge of the base plate 211, and the upper end extends upward to form a baffle. The base plate 211 and the surrounding plate 212 are integrally formed from plastic or metal. In addition, to enhance the structural strength of the outer casing segment 21, the upper end of the base plate 211 is provided with multiple ribs 213 radiating outward from the center of the base plate. The outer surface of the surrounding plate 212 is provided with multiple horizontally and vertically arranged ribs 214.

[0027] The outer edge of the outer casing 21 is provided with screw holes and a water-stop strip 22 is attached. The outer casing 21 is detachably connected by screws or interference fit.

[0028] Multiple fixing clips 23 are provided on the ribs 213 of the base plate 211. The number of fixing clips 23 corresponds to the number of ribs 213 on the base plate 21, and they are respectively provided on the ribs 213 at the end away from the surrounding plate 212 (i.e. the end close to the pile foundation 10).

[0029] The fixed clamp 23 includes a lead screw 231 and a fixed end 232. The lead screw 231 is a rotary handle lead screw, and the fixed end 232 is movably connected to the front end of the lead screw 231. Rotating the lead screw 231 can push the fixed end 232 forward.

[0030] The waterstop membrane 30 is a strip of a certain width, which is set up overlapping end to end around the pile foundation 10.

[0031] The installation process of the micro-cofferdam cover for this pile foundation is as follows:

[0032] The two-part outer shell 21 is wrapped around the outside of the pile foundation 10 and connected through screw holes on the outer edge of the outer shell 21. Through the encirclement of the outer shell 21, and utilizing the structural characteristics of the base plate 211 and the surrounding plate 212, an upward-opening working space is formed. This working space provides space for water-based operations on the pile foundation and supports for surrounding auxiliary structures. The encircled outer shell 21 forms a cylinder or cuboid around the pile foundation 10. In this embodiment, the two-part outer shell 21 surrounds the pile foundation 10, forming a cylinder around the pile foundation 10, thus isolating the pile foundation 10 from external water sources.

[0033] The waterstop membrane 30 is then wrapped around the pile foundation 10, positioning it between the pile foundation 10 and the outer shell 20. The upper end of the wrapped waterstop membrane 30 extends upwards above the base plate 211. Then, using the screw rod 231, the fixing end 232 is pushed forward, clamping and fixing the waterstop membrane 30 to the pile foundation 10. The lower end of the waterstop membrane 30 is located below the base plate 211, extending outwards and fixed with the clamping plate 31. The clamping plate 31 is then connected and fixed to the base plate 211 with fastening screws 32.

[0034] The micro-cofferdam cover for pile foundations according to the above embodiments includes a pile foundation, an outer shell, and a waterstop membrane. The outer shell includes at least two outer shell segments, which are detachably connected around the pile foundation. The waterstop membrane, in the form of a strip, is arranged around the pile foundation, with its bottom end positioned lower than the bottom of the outer shell. A fixing clip is provided on the outer shell segment, the clip including a threaded rod and a fixing end. The fixing end is movably connected to the threaded rod, and the fixing segment moves closer to the pile foundation under the push of the threaded rod. Additionally, connection holes and waterstop strips are provided at the edges of the outer shell segment. Based on this micro-cofferdam cover for pile foundations, the outer shell segments surround the pile foundation, isolating the pile foundation from the water in the surrounding environment and providing space for water-based operations. Furthermore, a waterstop membrane is provided at the bottom of the outer shell. This waterstop membrane isolates water at the contact point between the outer shell and the pile foundation, preventing external water from flowing into the outer shell from the connection point, thereby ensuring the dryness and safety of the internal space of the outer shell. Moreover, the multi-segment connection method of the outer shell segments facilitates the transportation and installation of the outer shell. Furthermore, the shell structure, which can be completed in two halves, involves fewer structural components, making it easy to assemble and saving on the cost of the cofferdam.

[0035] In addition, the outer casing includes a base plate and a surrounding plate. The surrounding plate is arranged around the outer edge of the base plate to form an upward-facing working space. This working space can provide working space for the water-based operations of the pile foundation, as well as support for the auxiliary structures of the pile foundation.

[0036] In addition, ribs are provided on both the inner and outer surfaces of the outer casing to enhance its structural strength. A fixing clamp is located on the inner rib of the outer casing near the pile foundation, allowing the fixing end to clamp the pile foundation by pushing it.

[0037] Furthermore, the upper end of the waterstop extends upwards to above the bottom inner side of the outer casing. When the upper end of the waterstop extends above the bottom inner side of the outer casing, the fixing end can simultaneously clamp the waterstop and the pile foundation. Additionally, the lower end of the waterstop is fixed by a clamping plate, which is connected to the bottom of the outer casing. Extending the waterstop into the outer casing further prevents water from flowing into the outer casing from the gap between the pile foundation and the outer casing, ensuring a dry environment within the working space.

[0038] Obviously, those skilled in the art can make various modifications and variations to this application without departing from the spirit and scope of this application. Therefore, if such modifications and variations fall within the scope of the claims and their equivalents, this application also intends to include such modifications and variations.
