Description

Technical Field

[0001] The utility model relates to the technical field of construction engineering, in particular to a multifunctional blocking cap for a drainage pipe well in a raft. Background Art

[0002] Pipe well dewatering is a commonly used dewatering method in construction projects. Usually, the dewatering cycle runs through the entire foundation development to the completion of backfill. The purpose of dewatering is not only to ensure the conditions for construction operations, but also to ensure that the buoyancy of groundwater does not damage the foundation structure.

[0003] During the sealing process, the traditional pipe well sealing method is sometimes unable to effectively seal the wellhead completely, resulting in basement water seepage in the later stage. In some areas, it cannot be discovered when the groundwater level is not high. When the groundwater level rises in the rainy season, because the pipe well is not completely sealed, the seeping groundwater spreads along various gaps in the basement floor, causing the basement to be damp, which in turn affects the functional use of the basement. Summary of the Invention

[0004] The technical problem to be solved by the utility model is to provide a multifunctional sealing cap for the drainage pipe well in the raft plate. The multifunctional sealing cap can realize the sealing of the drainage pipe well and the recycling and reuse of the pipe well, which can effectively improve the sealing efficiency and sealing quality of the pipe well. In addition, after adopting the multifunctional sealing cap, the pipe well can be converted into a construction water well, and combined with valves of different sizes, it can be suitable for different construction water use scenarios.

[0005] The technical solution adopted by the utility model to solve its technical problems is: to provide a multifunctional sealing cap for a drainage pipe well in a raft, including a sealing cap body, which is cylindrical, with the upper end of the sealing cap body sealed and the lower end open, a valve is provided in the middle of the upper end of the sealing cap body, and a plurality of water-stopping steel plates with downward-turned outer edges are sequentially provided on the circumference of the middle of the sealing cap body from top to bottom, and a circle of expansion water-stopping strips is arranged around the lower end of the water-stopping steel plate around the sealing cap body.

[0006] As a supplement to the technical solution described in the present invention, the blocking cap body and the water-stop steel plate are fixed by welding.

[0007] As a supplement to the technical solution described in the present invention, a valve connection port is provided in the middle of the upper end of the sealing cap body. The valve connection port is a threaded hole, and a valve is screwed onto the valve connection port.

[0008] As a supplement to the technical solution described in the present invention, there are two waterstop steel plates.

[0009] As a supplement to the technical solution described in the present invention, the waterstop steel plate is in a circular ring structure, and the outer diameters of the multiple waterstop steel plates gradually decrease from top to bottom.

[0010] Beneficial Effects: The utility model relates to a multifunctional plugging cap for a drainage manhole in a raft slab. A new multifunctional plugging cap is designed. After the plugging cap is effectively connected to the manhole, compared with traditional plugging measures, the downward-folding wings on both sides of the plugging cap can effectively change the water flow path, thereby achieving a waterproof effect. The water-expanding waterstop strips under the downward-folding wings can further enhance the waterproof effect. The utility model can not only effectively reduce water seepage after plugging, but also, after plugging, the valve placed on the top of the plugging cap can facilitate the use of the drainage manhole at the construction site, which is both environmentally friendly and saves project costs.

[0015] The present invention will be further described below with reference to specific embodiments. It should be understood that these embodiments are intended only to illustrate the present invention and are not intended to limit the scope of the present invention. Furthermore, it should be understood that after reading the contents of this invention, those skilled in the art may make various changes or modifications to the present invention, and that such equivalents also fall within the scope of the claims appended hereto.

[0016] The embodiment of the utility model relates to a multifunctional plugging cap for a drainage pipe well in a raft, such as Figures 1-3 As shown, it includes a sealing cap body 1, which is cylindrical, with the upper end sealed and the lower end open. A valve 2 is provided in the middle of the upper end of the sealing cap body 1, and a plurality of water-stop steel plates 4 with downward-turned outer edges are sequentially provided around the middle of the sealing cap body 1 from top to bottom. A circle of expansion water-stop strips 5 are arranged around the lower end of the water-stop steel plate 4 around the sealing cap body 1.

[0017] During the plugging construction process of the utility model, the plugging cap body 1 is first placed and connected to the drainage pipe well 8, and then the gap between the water-stop steel plate 4 around the plugging cap body 1 and the pipe well is filled with an expansion water-stop strip 5. After filling and fixing, the plugging cap body 1 and the pipe well are poured with micro-expansion anti-seepage concrete of C35 or above. Two circles of water-stop steel plates 4 with downward-turned outer edges are welded around the plugging cap body 1. After pouring the concrete, the water seeping out of the pipe well first passes through the water-expanding water-stop strip 5 when it encounters water, and then passes through the two water-stop steel plates 4 with downward-turned outer edges. This not only plays a role in blocking water, but also changes the water flow path that is not blocked by the expansion water-stop strip 5, thereby solving the problem of water seepage in the pipe well after plugging. After installation, please refer to Figure 1 As shown, a cushion layer 7 is provided below the raft 6 , a downdraft pipe well 8 is buried below the cushion layer 7 , and a multifunctional blocking cap is installed above the downdraft pipe well 8 .

[0018] The blocking cap body 1 and the water-stopping steel plate 4 are fixed by welding to ensure the stability of the connection between the two.

[0019] A valve connection port 3 is provided in the middle of the upper end of the sealing cap body 1. The valve connection port 3 is a threaded hole, and a valve 2 is screwed on the valve connection port 3. By replacing different variable valves, the connection of different water outlet pipe diameters can be achieved, so that the pipe well can be utilized during the non-precipitation period. Different pipe wells can cope with different construction water use scenarios.

[0020] There are two waterstop steel plates 4 ; the waterstop steel plates 4 are in an annular structure, and the outer diameters of the multiple waterstop steel plates 4 gradually decrease from top to bottom.

[0021] In the description of the present invention, it needs to be understood that the directions or positional relationships indicated by directional words such as "front, back, up, down, left, right", "horizontal, vertical, vertical, horizontal" and "top, bottom" are usually based on the directions or positional relationships shown in the drawings. They are only for the convenience of describing the present invention and simplifying the description. Unless otherwise specified, these directional words do not indicate or imply that the device or element referred to must have a specific direction or be constructed and operated in a specific direction. Therefore, they cannot be understood as limiting the scope of protection of the present invention; the directional words "inside and outside" refer to the inside and outside relative to the outline of each component itself.

[0022] For ease of description, spatially relative terms such as "above", "above", "on the upper surface of", "above", etc. may be used herein to describe the spatial positional relationship of a device or feature to other devices or features as shown in the figures. It should be understood that spatially relative terms are intended to include different orientations of the device in use or operation in addition to the orientation described in the figures. For example, if the device in the drawings is inverted, the device described as "above other devices or structures" or "above other devices or structures" will be positioned as "below other devices or structures" or "below other devices or structures". Thus, the exemplary term "above" can include both "above" and "below". The device can also be positioned in other different ways (rotated 90 degrees or in other orientations), and the spatially relative descriptions used here are interpreted accordingly.

[0023] In addition, it should be noted that the use of words such as "first" and "second" to limit components is only for the convenience of distinguishing the corresponding components. Unless otherwise stated, the above words have no special meaning and therefore cannot be understood as limiting the scope of protection of this utility model.
