Description

Technical Field

[0001] This utility model relates to the field of drainage pipe protection technology, and in particular to a protective device for laying municipal drainage pipes. Background Technology

[0002] Drainage pipes are mainly responsible for draining rainwater, sewage, and agricultural irrigation. Drainage pipes are divided into plastic drainage pipes, concrete pipes, and reinforced concrete pipes. Urban drainage systems are engineering facilities systems that treat and remove urban sewage and rainwater. They are a component of urban public facilities and are mostly buried underground.

[0003] Currently, when laying double-wall corrugated pipes, a common type of municipal drainage pipe, the ends of two double-wall corrugated pipes are usually plugged together. However, during on-site construction, some double-wall corrugated pipes may be damaged by collisions during transportation or installation, causing deformation at the joints. This deformation can prevent the pipes from being properly aligned during installation, requiring manual correction of the pipe ends, which increases the difficulty of the operation. Therefore, this invention provides a protective device for laying municipal drainage pipes to meet this need. Utility Model Content

[0004] The technical problem to be solved by this utility model is to provide a protective device for laying municipal drainage pipelines. By setting a first support ring, a connecting plate and a second support ring to support the end of the double-wall corrugated pipe body, the problem of deformation of the end interface of the double-wall corrugated pipe due to collision during transportation or laying and hoisting can be solved.

[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution:

[0006] A protective device for laying municipal drainage pipes includes a protective sleeve fitted onto a double-walled corrugated pipe body. The protective sleeve includes a first support ring, a connecting plate, and a second support ring. The two ends of one side of the connecting plate are fixedly connected to the first support ring and the second support ring, respectively. The first support ring, the connecting plate, and the second support ring form a U-shaped structure.

[0007] Optionally, a reinforcing frame is fixedly connected to the outer wall of the first support ring.

[0008] Optionally, the reinforcing frame includes transverse reinforcing ribs and longitudinal reinforcing ribs, the longitudinal reinforcing ribs being equidistantly distributed around the first support ring, the transverse reinforcing ribs being fixedly connected to the longitudinal reinforcing ribs, and one end of the longitudinal reinforcing ribs extending to the outer wall of the connecting plate.

[0009] Optionally, the inner wall of the first support ring is fixedly connected with a plurality of annularly distributed reinforcing plates, and a connecting ring is fixedly connected to the middle of the plurality of reinforcing plates.

[0010] Optionally, the reinforcing plate has a first weight-reducing hole in the middle, and the first support ring has a plurality of second weight-reducing holes distributed in an annular pattern in the middle.

[0011] Optionally, the reinforcing frame and the second weight-reducing hole are staggered.

[0012] Optionally, a first guide ring is fixedly connected to one side of the first support ring, and a second guide ring is fixedly connected to one side of the second support ring. The side cross-sectional views of the first guide ring and the second guide ring are both arc-shaped. The first guide ring and the second guide ring are both bent away from the double-walled corrugated pipe body. The bending directions of the first guide ring and the second guide ring are opposite. The first guide ring and the second guide ring form an octagon.

[0013] Optionally, the width of the second support ring is smaller than the width of the first support ring.

[0014] Compared with the prior art, this utility model has at least the following beneficial effects:

[0015] In the above scheme, by setting a protective sleeve, the first support ring, the connecting plate and the second support ring form a U-shaped structure, so that the first support ring, the connecting plate and the second support ring support the end of the double wall corrugated pipe body by sleeve, increasing the structural strength of the end of the double wall corrugated pipe body, so that the end of the double wall corrugated pipe body is not easily deformed during transportation or hoisting installation, and it is convenient for operators to connect and install the two double wall corrugated pipe bodies.

[0016] The first and second guide rings guide the double-walled corrugated pipe body when the first and second support rings are sleeved with it, helping the double-walled corrugated pipe body to be sleeved with the first and second support rings in sequence, thus facilitating the use of the first and second support rings.

[0024] The protective device for laying municipal drainage pipelines provided by this utility model will be described in detail below with reference to the accompanying drawings and specific embodiments. It should also be noted that, in order to make the embodiments more detailed, the following embodiments are the best and preferred embodiments, and those skilled in the art can also use other alternative methods to implement some known technologies; moreover, the accompanying drawings are only for more specific description of the embodiments and are not intended to specifically limit this utility model.

[0025] It should be noted that the use of terms such as "an embodiment," "an embodiment," "an exemplary embodiment," and "some embodiments" in the specification indicates that the described embodiment may include a specific feature, structure, or characteristic, but not every embodiment necessarily includes that specific feature, structure, or characteristic. Furthermore, when a specific feature, structure, or characteristic is described in connection with an embodiment, implementing such a feature, structure, or characteristic in conjunction with other embodiments (whether explicitly described or not) should be within the knowledge of those skilled in the art.

[0026] Generally, terms can be understood at least partly from their use in context. For example, depending at least partly on the context, the term "one or more" as used herein can be used to describe any feature, structure, or characteristic in a singular sense, or a combination of features, structures, or characteristics in a plural sense. Additionally, the term "based on" can be understood not necessarily to convey an exclusive set of factors, but rather, alternatively, depending at least partly on the context, to allow for the presence of other factors that are not necessarily explicitly described.

[0027] It is understood that the meanings of “on”, “above”, and “above” in this utility model should be interpreted in the broadest manner, such that “on” not only means “directly on” something, but also includes the meaning of being “on” something with an intervening feature or layer, and that “above” or “above” not only means “on” something, but also includes the meaning of being “on” something without an intervening feature or layer.

[0028] Furthermore, spatially related terms such as “below,” “under,” “lower,” “above,” and “upper” are used herein for convenience to describe the relationship of one element or feature to one or more other elements or features, as illustrated in the accompanying drawings. Spatially related terms are intended to cover different orientations in the use or operation of the device other than those depicted in the accompanying drawings.

[0029] like Figures 1 to 3As shown, an embodiment of this utility model provides a protective device for laying municipal drainage pipelines, including a protective sleeve 1 fitted onto a double-wall corrugated pipe body 5. The protective sleeve 1 includes a first support ring 2, a connecting plate 3, and a second support ring 4. The two ends of one side of the connecting plate 3 are fixedly connected to the first support ring 2 and the second support ring 4, respectively. The first support ring 2, the connecting plate 3, and the second support ring 4 form a U-shaped structure, so that the first support ring 2, the connecting plate 3, and the second support ring 4 support the ends of the double-wall corrugated pipe body 5 by fitting it onto the double-wall corrugated pipe body 5, increasing the structural strength of the ends of the double-wall corrugated pipe body 5. This makes it less likely for the ends of the double-wall corrugated pipe body 5 to deform during transportation or hoisting installation, and facilitates the docking and installation of two double-wall corrugated pipe bodies 5 by operators. A reinforcing frame 10 is fixedly connected to the outer wall of the first support ring 2. The reinforcing frame 10 includes transverse reinforcing ribs and longitudinal reinforcing ribs. The longitudinal reinforcing ribs are distributed equidistantly in a ring around the first support ring 2. The transverse reinforcing ribs are fixedly connected to the longitudinal reinforcing ribs, which increases the support strength of the first support ring 2. The reinforcing frame 10 also extends to the outer wall of the connecting plate 3 through one end of the longitudinal reinforcing ribs, increasing the strength of the first support ring 2 and the connecting plate 3. Several ring-shaped reinforcing plates 6 are fixedly connected to the inner wall of the first support ring 2. A connecting ring 7 is fixedly connected to the middle of the reinforcing plates 6, which strengthens the second support ring 4 and further improves the structural strength of the protective sleeve 1. This better protects and supports the end of the double-wall corrugated pipe body 5, providing more stable support for the end of the double-wall corrugated pipe body 5 and reducing the possibility of deformation of the end of the double-wall corrugated pipe body 5 during transportation or hoisting. By making the width of the second support ring 4 smaller than that of the first support ring 2, when the protective sleeve 1 is fitted with the double-wall corrugated pipe body 5, the first support ring 2 first makes a preliminary fit with the double-wall corrugated pipe body 5, and then makes a secondary fit with the second support ring 4. This reduces the difficulty of fitting and makes it easier to take out the double-wall corrugated pipe body 5 and use it.

[0030] As one implementation method in this embodiment, such as Figure 2 and Figure 3As shown, a first weight-reducing hole 8 is provided in the middle of the reinforcing plate 6, and several annularly distributed second weight-reducing holes 9 are provided in the middle of the first support ring 2. This allows the first weight-reducing hole 8 to reduce the weight of the reinforcing plate 6, and the second weight-reducing holes 9 to reduce the weight of the first support ring 2, thus reducing the weight during hoisting and transportation. The reinforcing frame 10 and the second weight-reducing holes 9 are interleaved to prevent interference, ensuring normal operation. A first guide ring 11 is fixedly connected to one side of the first support ring 2, and a second guide ring 12 is fixedly connected to one side of the second support ring 4. The first guide ring 11 and the second guide ring 12... The side sectional views of 2 are all arc-shaped. The first guide ring 11 and the second guide ring 12 are both bent away from the double-walled corrugated pipe body 5. The bending directions of the first guide ring 11 and the second guide ring 12 are opposite. The first guide ring 11 and the second guide ring 12 form an octagon, so that the first guide ring 11 and the second guide ring 12 can guide the double-walled corrugated pipe body 5 when the first support ring 2 and the second support ring 4 are sleeved with the double-walled corrugated pipe body 5, so as to help the double-walled corrugated pipe body 5 to be sleeved with the first support ring 2 and the second support ring 4 in sequence, which facilitates the use of the first support ring 2 and the second support ring 4.

[0031] The working principle of the technical solution provided by this utility model is as follows:

[0032] In use, the first support ring 2 and the second support ring 4 are connected to the ends of the double-wall corrugated pipe body 5, so that the ends of the double-wall corrugated pipe body 5 are sequentially sleeved with the first support ring 2 and the second support ring 4. The first support ring 2, the connecting plate 3 and the second support ring 4 form a U-shape, so that the first support ring 2, the connecting plate 3 and the second support ring 4 support the ends of the double-wall corrugated pipe body 5 by sleeve, increasing the structural strength of the ends of the double-wall corrugated pipe body 5, so that the ends of the double-wall corrugated pipe body 5 are not easily deformed during transportation or hoisting and installation, and it is convenient for operators to connect and install the two double-wall corrugated pipe bodies 5.

[0033] By setting a first support ring 2, a first guide ring 11, a second support ring 4, and a second guide ring 12, the first guide ring 11 and the second guide ring 12 can guide the double-wall corrugated pipe body 5 when the first support ring 2 and the second support ring 4 are sleeved with the double-wall corrugated pipe body 5, so as to help the double-wall corrugated pipe body 5 to be sleeved with the first support ring 2 and the second support ring 4 in sequence, which facilitates the use of the first support ring 2 and the second support ring 4.

To provide the public with a thorough understanding of this utility model, specific details are described in detail in the following preferred embodiments; however, those skilled in the art will fully understand this utility model even without these detailed descriptions. Furthermore, to avoid unnecessary confusion regarding the essence of this utility model, well-known methods, processes, procedures, components, and circuits are not described in detail.

[0035] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
