Description

Technical Field

[0001] The present invention relates to the technical field of municipal sewage and drainage engineering, in particular to a quickly installed bracket-type drainage well. Background Art

[0002] Drainage wells are set up to facilitate the installation and maintenance of urban sewage discharge systems. They are generally located at pipe intersections, bends, places where pipe diameters or slopes change, and at certain intervals on straight pipes to facilitate the inspection of ancillary structures.

[0003] Currently, the most commonly used finished drainage wells are all made of PE plastic. The connecting seals between the pipe and the drainage well are all rubber products. The drainage well and the pipe are connected in this order: well, pipe, well, in this order. For example, when connecting the starting well to the pipe, first put a rubber sealing ring on the outside of the pipe, then use a tensioner to pull the pipe with the sealing ring into the water outlet interface of the starting well. After pulling it in, wrap it with heat shrink tape at the interface. After wrapping it, heat shrink tape is heated with fire to shrink it to meet the sealing requirements. The method for connecting the second well to the pipe is as follows: when the pipe is connected to the water inlet of the second well, put a rubber sealing ring on the outside of the pipe, then use a tensioner to pull the second inspection well toward the pipe, pull the drainage end of the inspection well into the pipe, and then wrap it with heat shrink tape at the interface. After wrapping it, bake it with fire to shrink the heat shrink tape and seal the interface. The connection method between the outlet of the second well and the pipe is the same as the installation method of the starting well. Other pipes and wells are connected in this way. Before backfilling, the connected pipes and wells must be wrapped with fine sand to prevent stones, rocks and sharp objects from damaging the well body. Backfilling can only be done after wrapping.

[0004] During the construction and installation of sewage treatment projects, since drainage wells are mostly made of PE plastic, the connection between the sewage pipe and the manhole is sealed with a rubber seal, which is then wrapped with heat shrink tape. The heat shrink tape is then baked to shrink and seal the joint. This complex process slows down project progress. Furthermore, the pipe diameters required by each work section often vary, and the pipes and drainage wellheads often do not match. Different models of drainage wells and seals are required, significantly increasing the difficulty of the connection and sealing project and making it difficult to ensure the quality of the installation seal. The seals connecting the drainage well and the pipe are all made of rubber. Rubber products are easily affected by ambient temperature and are prone to hardening, loss of toughness, damage during installation, and loss of physical properties. This makes it difficult to ensure the stable operation of the sewage system during use. Construction personnel must also be proficient in installation and sealing methods. The installation process also requires the use of liquefied petroleum gas as a fire source, which poses a major fire safety hazard during construction. During backfilling, the well body must be surrounded with fine sand.

[0005] Therefore, there is an urgent need for a drainage well that is quick to install, efficient and reliable, sturdy and durable, highly adaptable, has a large well body space, is simple and easy to operate, and has more stable physical properties and system operation of the well body and the connecting sealing parts. It does not require the well body to be wrapped with fine sand during backfilling and has no special requirements for backfill soil. Summary of the Invention

[0006] The purpose of the present invention is to provide a quick-install bracket-type drainage well, which can effectively solve the problems of existing drainage wells when docking and installing with pipelines, such as long installation time, low efficiency, poor adaptability, poor sealing between the pipeline and the well body, high technical requirements for installation workers, and potential fire safety accidents during the installation process.

[0007] In order to solve the above technical problems, the present invention adopts the following technical solutions:

[0008] A quick-install bracket-type drainage well of the present invention includes a well seat, wherein the well seat has a well cavity with a closed bottom and an open top, and the top of the side wall of the well cavity is provided with an opening for accommodating a pipe, which is through-through and open at the top, and the inner wall of the opening extends toward the outside of the well seat and / or the inside of the well seat to form a pipe bracket.

[0009] Furthermore, the inner wall of the opening and the inner wall of the pipe bracket together constitute the inner wall of the supporting interface, and the inner end and / or outer end of the inner wall of the supporting interface extend inward to form a U-shaped or approximately U-shaped pipe clamping rib, and slots are respectively provided on both sides of the pipe clamping rib. The upper opening of the pipe clamping rib is plugged with a plug-in plate through the slots on both sides, and the bottom of the plug-in plate is provided with an upwardly concave arched groove, and a circular or approximately circular pipe placement channel is formed between the inner wall of the groove and the inner wall of the pipe clamping rib, and a sealing material-filled space is formed between the pipe clamping rib, the plug-in plate, the inner wall of the supporting interface and the outer wall of the pipe.

[0010] Furthermore, the pipe is a corrugated pipe, the inner edge of the pipe positioning rib is inserted into the trough on the outside of the corrugated pipe, and the inner wall of the groove is inserted into the trough on the outside of the corrugated pipe to position the corrugated pipe.

[0011] Furthermore, the length of the pipe bracket is at least 5 cm or 5 times the wall thickness of the well seat.

[0012] Furthermore, the inner wall surface of the opening is U-shaped or approximately U-shaped, and the pipe bracket is a U-shaped or approximately U-shaped structure formed by the inner wall of the opening extending toward the outside of the well seat and / or extending toward the inside of the well seat.

[0013] Furthermore, the upper end of the opening is higher than the top of the pipe that can be placed in the opening.

[0014] Furthermore, an extension plate is provided on the top of the pipe bracket, and the extension plate is inserted and installed on the top of the pipe bracket or is integrated with the pipe bracket. The top of the extension plate is higher than the top of the pipe that can be placed in the opening.

[0015] Furthermore, the well seat and the pipe bracket are an integrated structure formed by one-time molding or casting.

[0016] Furthermore, an upper well body with a hollow interior is assembled on the top of the well seat, and a mounting groove is provided on the top of the well seat. The lower end of the upper well body sits in the mounting groove, and the upper well body is sealed and assembled on the well seat by adhesive.

[0017] Furthermore, the well seat is in a basin shape or approximately in a basin shape, the upper well body is in a truncated cone shape or approximately in a truncated cone shape, and reinforcing ribs are provided on the bottom and outer side wall of the well seat.

[0019] The quick-install bracket-type drainage well of the present invention has a compact structure design. When connecting the pipes, the pipes can be directly placed on the openings and the pipe brackets without moving the well seat, which greatly speeds up the installation efficiency of the drainage well. At the same time, the quick sealed connection with the pipe can be completed by injecting sealing material into the openings and the pipe brackets. The entire process does not use rubber parts for sealing, avoiding the shortcomings of rubber parts that are hardened and easily damaged due to cold weather, resulting in uncertain sealing effects and hidden leakage points that are difficult to repair.

[0029] The technical solutions provided by various embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0030] Example 1

[0031] like Figures 1 to 3 As shown, the quick-install bracket-type drainage well of the first embodiment includes a well seat 1, which has a well cavity with a closed bottom and an open top. The top of the side wall of the well cavity is provided with an opening 2 for accommodating a pipe, which is through-through and open at the top. The inner wall of the opening 2 extends toward the outside of the well seat 1 and / or toward the inside of the well seat 1 to form a pipe bracket 3.

[0032] Among them, the inner wall of the opening 2 can extend into the inside of the well seat 1 to form a pipe bracket 3. At this time, through the setting of the opening 2 and the pipe bracket 3, when connecting and installing the pipeline, the drainage well is first placed on the well base, and then the pipeline is placed directly in the opening 2 from top to bottom. At this time, the pipeline is supported on the pipe bracket 3, and then the wellbore or the upper section of the well seat 1 is sealed and installed on the top of the well seat 1, and then the opening 2 and the pipe bracket 3 are filled with sealing materials, such as concrete or anti-seepage concrete, and then backfilled.

[0033] In this embodiment, by setting the opening 2 and the pipe bracket 3, there is no need to move the well seat 1 when connecting with the pipeline, which reduces the operation links and speeds up the pipeline installation speed. After pouring concrete sealing material into the opening 2 and the pipe bracket 3, the well seat 1 can be backfilled, realizing an installation method of excavation, laying, installation and backfilling, freeing up construction work surface and space for simultaneous cross-construction projects, and greatly speeding up the overall construction progress of the project. In addition, the sealing method between the pipeline and the well seat 1 is simple, convenient, easy to implement, and the sealing quality is guaranteed. During the installation process, no rubber sealing ring is required and it is suitable for pipelines of different sizes and models within a certain range. It not only avoids the rubber sealing ring from hardening and being easily damaged due to cold weather, resulting in uncertain sealing effect, but also overcomes the shortcomings of hidden and difficult to repair leakage points. It also has strong adaptability. During the installation process, there is no need to use fire to bake the heat shrink tape to seal the bracket-type drainage well and the pipeline. This not only avoids the safety hazards of fire accidents, but also eliminates the need to repeatedly lift the pipeline and the bracket-type drainage well to bake the bottom and circumference of the pipeline, shortening the installation time and reducing the labor intensity of the installation operation.

[0034] Specifically, the upper end of the opening 2 is higher than the top of the pipe that can be placed in the opening 2. When the pipe is placed in the opening 2 and the opening 2 and the pipe bracket 3 are filled with sealing material, the sealing material can completely wrap the outer wall of the pipe, reducing the chance of leakage to a minimum.

[0035] Preferably, the length of the pipe bracket 3 is at least 5 cm or 5 times the wall thickness of the well seat 1. If required, the inner wall of the opening 2 extends outward from the well seat 1 to form the pipe bracket 3. The pipe bracket 3 is 10 cm long. In this case, when the sealing material fills the pipe bracket 3 and the outer wall of the pipe, the sealing layer formed by the sealing material and wrapped around the outside of the pipe is longer, which can better ensure the sealing performance of the pipe.

[0036] Furthermore, the inner wall surface of the opening 2 is U-shaped or approximately U-shaped, and the pipe bracket 3 is a U-shaped or approximately U-shaped structure formed by the inner wall of the opening 2 extending toward the outside of the well seat 1 and / or extending toward the inside of the well seat 1. In this case, the inner wall surface of the opening 2 is a U-shaped surface composed of a circular arc-shaped top surface and two vertical planes on both sides, and the pipe bracket 3 is a U-shaped structure formed by the inner wall of the opening 2 extending toward the outside of the well seat 1. Since pipes are generally circular, when the pipe is placed on the opening 2 and the pipe bracket 3, and concrete sealing material is poured into the opening 2 and the pipe bracket 3, the sealing material can better fill the gap between the pipe and the inner wall of the opening 2 and the inner wall of the pipe bracket 3, thereby better sealing the pipe and the drainage well together.

[0037] like Figure 2 、 Figure 3 As shown, the inner wall of the opening 2 and the inner wall of the pipe bracket 3 together constitute the inner wall of the supporting interface, and the inner end and / or outer end of the inner wall of the supporting interface extend inward to form a U-shaped or approximately U-shaped pipe retaining edge 5. According to the needs, the inner end and outer end of the inner wall of the supporting interface respectively extend inward to form a U-shaped pipe retaining edge 5 whose inner edge can be inserted into the trough on the outside of the corrugated pipe placed in the opening 2. Since most of the existing drainage pipes are corrugated pipes, through the setting of the U-shaped pipe retaining edge 5, when the corrugated pipe is placed in the opening 2, the inner edge of the pipe retaining edge 5 can be stuck in the trough on the outside of the corrugated pipe, thereby positioning the corrugated pipe and preventing the corrugated pipe from shifting relative to the well seat 1. In addition, due to the presence of the pipe retaining edge 5, it can block the sealing material when pouring the sealing material, so that the sealing material is better filled between the outer wall of the pipe and the inner wall of the supporting interface.

[0038] like Figure 2 、 Figure 3 As shown, slots 6 are provided on both sides of the pipe retaining rib 5. Insert plates 7 are inserted into the upper opening 2 of the pipe retaining rib 5 through the slots 6 on both sides. An upwardly concave arcuate groove 8 is provided at the bottom of the insert plate 7. A circular or approximately circular pipe placement channel is formed between the inner wall of the groove 8 and the inner wall of the pipe retaining rib 5. Depending on the needs, the insert plate 7 is a rectangular plate with an arcuate groove 8 at the bottom. The two sides of the insert plate 7 are respectively inserted into the slots 6 on the two sides of the pipe retaining rib 5. During installation, the corrugated pipe is placed on the pipe retaining rib 5, and then the insert plate 7 is inserted into the pipe retaining rib 5. The inner wall of the groove 8 can be inserted into the outer trough of the corrugated pipe to position the corrugated pipe.

[0039] In this embodiment, through the arrangement of the pipe retaining rib 5 and the plug-in plate 7, when the pipe is installed in the pipe placement space formed by the aforementioned two, a sealing material-filled space is formed between the pipe retaining rib 5, the plug-in plate 7, the inner wall of the supporting interface and the outer wall of the pipe, which can further facilitate the sealing of the installation gap between the pipe and the inner wall of the supporting interface by the sealing material. In addition, since the plug-in plate 7 and the pipe retaining rib 5 are installed together by plugging, the plug-in plates 7 with grooves 8 of different radii can be prefabricated in advance, and the corresponding plug-in plates 7 can be selected according to the outer diameter of the actually installed pipe, which has strong applicability.

[0040] Specifically, the well seat 1 and the pipe bracket 3 are an integrated structure formed by one-time molding or casting, so that the overall structure has strong strength and strong pressure bearing capacity.

[0041] At the same time, an upper well body 9 with a hollow interior is assembled on the top of the well seat 1. The inner cavity of the upper well body 9 is connected to the well cavity of the well seat 1 to form a combined well cavity that is connected from top to bottom. Specifically, a mounting groove 11 can be provided on the top of the well seat 1. The lower end of the upper well body 9 is seated in the mounting groove 11. The upper well body 9 can be quickly and sealedly assembled on the well seat 1 using an adhesive. The upper well body 9 seals the upper end of the opening 2 through the upper well body 9, facilitating the complete sealing of the opening 2 using the sealing material.

[0042] Preferably, the well base 1 is in a basin shape or approximately in a basin shape, and the well body is in a truncated cone shape or approximately in a truncated cone shape. Reinforcing ribs 10 are provided on the bottom and outer wall of the well base 1. The well base 1 is in a basin shape and the well body is in a truncated cone shape. After being assembled, the drainage well has a strong pressure-bearing capacity and a large internal cavity space. The provision of the reinforcing ribs 10 can enhance the structural strength of the well base 1 and ensure its service life.

[0043] Example 2

[0044] like Figure 4 As shown, the difference between the second embodiment and the first embodiment is that an extension plate is provided on the top of the pipe bracket 3, and the extension plate is inserted and installed on the top of the pipe bracket 3 or is integrated with the pipe bracket 3. The top of the extension plate is higher than the top of the pipe that can be placed in the opening 2.

[0045] Among them, the extension plate is inserted into the top of the pipe bracket 3. According to needs, a slot 6 is provided on the top of the pipe bracket 3, and the bottom end of the extension plate is inserted into the slot 6 to realize the plug-in connection with the pipe bracket 3. Through the setting of the extension plate, when the inside of the pipe bracket 3 is filled with sealing material, the sealing material can completely wrap the pipe, thereby reducing the chance of pipe leakage, and is also conducive to completely sealing the opening 2 through the sealing material.

[0046] The embodiments described above are merely descriptions of preferred embodiments of the present invention and are not intended to limit the scope of the present invention. Without departing from the spirit of the present invention, various modifications and improvements made to the technical solutions of the present invention by persons skilled in the art should fall within the scope of protection defined by the claims of the present invention.
