Description

Technical Field

[0001] The utility model belongs to the technical field of pipe well covers, and particularly relates to a detachable temporary protection cover for a drain pipe well. Background Art

[0002] With the development of urban construction, there are more and more municipal public works in cities and towns. Temporary safety protection during the construction of rain and sewage wells and cable communication wells is particularly important. There is often a safety protection vacuum period from the installation of municipal rain and sewage, cable communication pipelines to the completion of the installation of rain and sewage well covers. To avoid water accumulation in the pipe well and high-altitude falling of construction workers at the construction site before the completion of the installation of the pipe well cover, a temporary protection cover needs to be set at the wellhead.

[0003] Existing temporary protection covers are often made of simple templates and directly placed at the wellhead. During the construction process, such temporary protection covers are extremely prone to problems such as incomplete closure and cover displacement due to bumps and bad weather such as strong winds, posing certain risks to the safety control of the construction site. Summary of the Utility Model

[0004] In view of the above problems in the prior art, the present application proposes a detachable temporary protection cover for a drain pipe well, which solves the problems of incomplete closure and cover displacement of traditional temporary protection covers due to bumps and bad weather such as strong winds.

[0005] The utility model proposes a detachable temporary protection cover for a drain pipe well, which includes two semi-circular covers. The two semi-circular covers are spliced to form a complete circular cover. One of the semi-circular covers is provided with a raised strip at the splicing seam; the raised strip overlaps on the other semi-circular cover; each semi-circular cover is internally provided with a hollow water storage bin, and a water injection hole communicated with the water storage bin is arranged at the end face of the semi-circular cover.

[0006] Further, the arc edges of the two semi-circular covers are provided with downward-extending extended edges.

[0007] The temporary protection cover is temporarily fixed to the drain pipe well wall through the extended edges, which can prevent the temporary protection cover from sliding and also prevent sundries from falling into the drain pipe well.

[0008] Further, a drain hole communicated with the water storage bin and a water stop plug for closing or opening the drain hole are arranged on the side wall of each semi-circular cover.

[0009] By draining water through the drain hole, the self-weight of the temporary protection cover can be freely adjusted to meet the usage conditions in various weather such as strong winds.

[0010] Further, a handle is arranged at the upper end of each semi-circular cover.

[0011] Further, each of the semi-circular covers includes a semi-circular top plate, a semi-circular bottom plate, a vertical sealing plate, and an arc-shaped sealing plate; both ends of the vertical sealing plate are connected to the head and tail of the arc-shaped sealing plate to enclose a semi-circular ring cavity; the semi-circular top plate closes the upper end of the semi-circular ring cavity, and the semi-circular bottom plate closes the lower end of the semi-circular ring cavity.

[0012] Further, the semi-circular top plates of the two semi-circular covers are spliced to form a splicing seam, and an upper seal is covered above the splicing seam; the upper seal is connected to one of the semi-circular top plates.

[0013] The beneficial effects of the present utility model include: using two semi-circular covers in combination and splicing to form a complete circular cover can avoid the problem that it is not easy to install and use when there is a height difference between the wellhead and the current road surface before the municipal roadbed is backfilled. When there are bad weather such as strong winds, or when vehicles and pedestrians pass by the wellhead frequently, a certain amount of water can be injected into the water storage chamber through the water injection hole to increase the self-weight of the temporary protective cover, avoiding displacement caused by mechanical equipment and construction personnel or being blown open by strong winds. Using the raised strips to cover the overlapping or splicing gaps not only increases the safety of the overlapping position of the temporary protective cover, but also can prevent rainwater from seeping into the pipe well during rainy days, causing inconvenience to construction.

[0019] The following further describes the present utility model in detail with reference to the drawings and specific embodiments.

[0020] As Figures 1-4As shown in the figure, the detachable temporary protective cover plate of the drainage pipe well of the present utility model includes: two semi-circular cover plates 1, and the two semi-circular cover plates 1 are spliced or overlapped to form a complete circular cover plate. One of the semi-circular cover plates 1 is provided with a raised strip at the splicing seam; the raised strip overlaps on the other semi-circular cover plate 1; the raised strip covers the overlapping gap, which not only increases the safety of the overlapping position of the cover plate, but also can prevent rainwater from seeping into the pipe well on rainy days, causing inconvenience to construction.

[0021] A handle 3 is provided at the upper end of each semi-circular cover plate 1. Through the handle 3, the semi-circular cover plate 1 can be easily taken.

[0022] A hollow water storage bin 6 is arranged inside each semi-circular cover plate 1. A water injection hole 4 communicating with the water storage bin is arranged on the end face of the semi-circular cover plate 1, and the water injection hole 4 is located at the upper end of the semi-circular cover plate 1.

[0023] In case of bad weather such as strong wind, or when there are frequent vehicles and pedestrians passing by the wellhead, a certain amount of water can be injected into the hollow water storage bin 6 of the cover plate through the water injection hole 4 to increase the self-weight of the protective cover plate, so as to avoid displacement caused by mechanical equipment and construction personnel or being blown open by strong wind.

[0024] Each semi-circular cover plate 1 includes a cover plate body 5, and the cover plate body 5 includes a semi-circular top plate, a semi-circular bottom plate, a vertical sealing plate and an arc-shaped sealing plate; both ends of the vertical sealing plate are connected to the head and tail of the arc-shaped sealing plate to enclose a semi-circular ring cavity; the semi-circular top plate is closed at the upper end of the semi-circular ring cavity, and the semi-circular bottom plate is closed at the lower end of the semi-circular ring cavity.

[0025] The two semi-circular cover plates 1 are closed by overlapping. One of the semi-circular cover plates 1 is provided with an upper sealing strip. When overlapping and closing, the upper sealing strip seals the joint to reduce rainwater seepage into the well. The two semi-circular cover plates 1 are both composed of the cover plate body 5, with a hollow water storage bin 6 arranged inside, a water injection hole 4 is respectively arranged at the upper end, and a drain hole 7 is arranged at the side. Handles 3 are respectively arranged on the upper parts of the semi-circular cover plates 1, and the sides are provided with extended edge wraps 2.

[0026] After the construction of the drainage pipe well is completed, the detachable temporary protective cover plate formed by overlapping the two semi-circular cover plates 1 can be placed on the drainage pipe well, and is temporarily fixed to the drainage pipe well wall through the extended edge wrap 2 to prevent the protective cover plate from sliding and also prevent sundries from falling into the drainage pipe.

[0027] When the designed cover plate is installed at the wellhead and the detachable temporary protective cover plate needs to be removed, first drain the water in the hollow water storage bin 6 completely through the drain hole 7, then separate the two semi-circular cover plates 1 by holding the handles 3, and then take them off and stack them centrally for storage and then transfer them to other drainage pipe wells for protection use.

[0028] If the temporary protective cover plate needs to be removed due to subsequent construction requirements, the permanent protective cover plate of the drainage pipe well must be constructed in time to prevent safety risks.

[0029] The above are only the preferred embodiments of the present utility model. The protection scope of the present utility model is not limited to the above embodiments. All technical solutions falling within the concept of the present utility model belong to the protection scope of the present utility model. It should be noted that for those of ordinary skill in the art, several improvements and refinements made without departing from the principle of the present utility model should also be regarded as within the protection scope of the present utility model.
