Description

Technical Field

[0001] The invention relates to the technical field of municipal sewage and drainage engineering, and in particular to a quickly installed slot-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

[0011] Furthermore, a concave water flow trough parallel to the length direction of the supporting groove is provided on the top surface of the bottom plate corresponding to the position of the pipe supporting seat, and the inner wall of the concave water flow trough is an arc surface.

[0012] Furthermore, the cross section of the slot-type pipe interface is in an inverted U shape or approximately in an inverted U shape.

Thus, features defined as "first" and "second" may explicitly or implicitly include one or more of the features.

For example, they may refer to fixed connections, detachable connections, or integral connections; they may refer to direct connections or indirect connections through an intermediate medium; they may refer to internal communication between two components or an interaction between two components. Those skilled in the art will understand the specific meanings of the above terms in the present invention based on specific circumstances.

[0030] The technical solutions provided by various embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0031] like Figures 1 to 5 As shown, the quick-installation slot-type drainage well of this embodiment includes a well body 1 with a hollow interior, and a slot-type pipe interface 2 with a hollow interior and an open bottom that can be suspended on the pipe to be installed is provided through the bottom end of the well wall of the well body 1. The slot-type pipe interface 2 protrudes and extends to the interior and / or exterior of the well body 1, and a sealing material injection port 3 that passes through the inner and outer walls of the slot-type pipe interface 2 is provided on the wall of the slot-type pipe interface 2 corresponding to the internal position and / or external position of the well body 1.

[0032] Specifically, according to requirements, the bottom end of the slot-type pipe interface 2 is flush with the bottom end of the well wall of the well body 1. In this embodiment, two corresponding slot-type pipe interfaces 2 are provided through the bottom end of the well wall of the well body 1, and the slot-type pipe interfaces 2 protrude and extend into the interior of the well body 1.

[0033] Among them, the slot-type pipe interface 2 can protrude and extend to the outside of the well body 1. Through the setting of the slot-type pipe interface 2, the well body 1 can be directly suspended on the pipe. When connecting and installing with the pipe 13, the pipe 13 can be first connected as a whole in the foundation pit after excavation to form a complete pipeline, and then the bottom opening of the slot-type pipe interface 2 is aligned with the pipe 13 at the pre-installation position of the drainage well, and then the slot-type drainage well is directly lowered so that the slot-type pipe interface 2 is suspended on the pipe, and then it can be backfilled, which can free up working surface and space for other ground construction projects. After backfilling, concrete is injected into the bottom of the well body 1 to seal the bottom opening of the well body 1, and then both sides of the pipe are filled with concrete. The pouring height is about half of the pipe height, and then the sealing material is poured into the installation gap between the inner wall of the slot-type pipe interface 2 and the outer wall of the pipe.

[0034] According to the needs, the sealing material can be a fluid sealing material, a foamed sealing material, a powdered sealing material or concrete. The installation gap between the pipe and the inner wall of the slot-type pipe interface 2 is sealed by pouring the sealing material. Before delivery or when it is raised upward, a skylight is cut out in the upper half of the pipe in the well and it can be put into use. There is no need to cut the pipe at the slot-type drainage well.

[0035] At this time, the setting of the slot-type pipe interface 2 abandons the original connection method and sealing method between the pipe and the drainage well, and realizes the installation method of excavation, laying, installation and backfilling, freeing up construction work surface and space for simultaneous cross-construction projects, greatly speeding up the overall construction progress of the project. In addition, the sealing method between the pipe and the well body 1 is simple, convenient, easy to understand and learn, easy to implement and operate, and the sealing quality is guaranteed. No sealing ring is required during the installation process and it is suitable for pipes of different sizes and models within a certain range. It has strong adaptability, and during the installation process, there is no need to use fire to bake the heat shrink tape to seal the slot-type drainage well and the pipe. Not only does it avoid the safety hazards of fire accidents, but it also does not need to repeatedly lift the pipe and the drainage well to bake the bottom and circumference of the pipe, shortening the installation time and reducing the labor intensity of the installation operation.

[0036] In addition, since the pipeline is laid as a completed pipeline, there is no need to accurately measure the cutting size between the pipeline and the drainage well during the laying process, which reduces the number of work items and links, thereby reducing pauses and waiting in the laying process, simplifying the laying work content, and greatly speeding up the laying speed. Finally, since the pipeline does not need to be cut and the pipeline has no broken ends, there are fewer leakage points, the integrity of the pipeline is not weakened, the sewage in the pipeline flows faster and smoother, and the probability of dirt deposition and clogging in the pipeline can be reduced to a minimum. The setting of the sealing material filling port 3 is more conducive to construction personnel pouring sealing material into the installation gap between the pipeline and the inner wall of the slot-type pipeline interface 2 to seal the installation gap.

[0037] Specifically, according to needs, the sealing material filling port 3 can be set at the top position of the slot-type pipe interface 2. The sealing material poured from the sealing material filling port 3 can be more evenly filled in the installation gap between the pipe and the well body 1, thereby ensuring good sealing.

[0038] Preferably, the length of the slot-type pipe interface 2 protruding from the inside or outside of the well body 1 is at least 5 centimeters, or 5 times the wall thickness of the well body 1. When the sealing material completely fills the slot-type pipe interface 2 and the outer wall of the pipe, the sealing layer formed by the sealing material wrapped around the outside of the pipe is longer, which can better ensure the sealing performance of the pipe. Furthermore, the slot-type pipe interface 2 protrudes 10 centimeters into the interior of the well body 1.

[0039] like Figure 1 、 Figure 2 、 Figure 3 and Figure 5 As shown, the cross-section of the slot-type pipe interface 2 is an inverted U-shape or an approximately inverted U-shape, and the inner wall surface of the slot-type pipe interface 2 is an inverted U-shaped surface composed of a circular arc-shaped top surface and vertical planes on both sides. Since the pipeline is generally circular, and the cross-section of the slot-type pipe interface 2 is an inverted U-shape or an approximately inverted U-shape design, when the slot-type pipe interface 2 is suspended on the pipeline, the gap between the pipeline and the inner wall of the slot-type pipe interface 2 is smaller, and the sealing material pouring port 3 is provided on the top wall of the slot-type pipe interface 2. When the sealing material is poured into the sealing material pouring port 3 at the top of the slot-type pipe interface 2, the sealing material can better fill the installation gap between the pipeline and the well body 1, further improving the sealing performance.

[0040] like Figure 1 、 Figure 2 、 Figure 3 and Figure 5 As shown, the inner end of the inner wall and / or the outer end of the inner wall of the slot-type pipe interface 2 extend inward to form an inverted U-shaped sealing material rib 4 that can be inserted and buckled on the outside of the pipe to be installed. At this time, the inner end and the outer end of the inner wall of the slot-type pipe interface 2 respectively extend inward to form an inverted U-shaped sealing material rib 4 whose inner edge can be inserted and buckled in the trough on the outside of the corrugated pipe to be installed. Since most of the existing drainage pipes are corrugated pipes, through the setting of the inverted U-shaped sealing material rib 4, when the slot-type pipe interface 2 is suspended on the corrugated pipe, the inner edge of the sealing material rib 4 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 body 1. In addition, due to the presence of the sealing material rib 4, 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 slot-type pipe interface 2.

[0041] like Figure 2 、 Figure 3As shown, a ridge 5 and / or groove is provided on the inner wall of the well body 1 near the bottom of the inner wall. Specifically, an annular ridge 5 is provided on the inner wall of the well body 1 near the bottom of the inner wall along the circumference of the inner wall of the well body 1. In other embodiments, an annular groove may be provided on the inner wall of the well body 1 near the bottom of the inner wall along the circumference of the inner wall of the well body 1.

[0042] At present, in order to prevent the drainage well from settling or tilting during use, a concrete platform is generally poured at the bottom of the drainage well in advance when the drainage well is installed. After the concrete platform solidifies, the drainage well is placed on the concrete platform. Since the pouring and solidification of the concrete platform require a certain amount of time, this invisibly increases the installation time of the drainage well. By providing a ridge 5 or a groove on the inner wall of the well body 1 near the bottom end of the inner wall, there is no need to pour the concrete platform in advance during installation and use. After the well body 1 and the pipeline are connected and placed in the buried pit, concrete is directly poured into the bottom of the well body 1 until the concrete overflows the ridge 5 or the groove. After the concrete solidifies, a concrete layer is formed that wraps the ridge 5 or fills the groove. The concrete layer, the well body 1 and the pipeline are fixedly connected together, which not only ensures that the well body 1 will not settle or tilt during later use, but also increases the ring stiffness of the well body 1, thereby improving the structural strength of the entire slot-type drainage well. When installing the slot-type drainage well, there is no need to pour a concrete platform at the bottom to prevent settling or tilting, thereby further accelerating the installation efficiency.

[0043] Specifically, there are at least two slot-type pipe interfaces 2, two of which are arranged opposite each other, and at least one of which is provided with a blind plate on its inner wall at a position corresponding to the wellbore wall, thereby isolating the internal space of the slot-type pipe interface 2. The provision of the blind plate allows users to choose whether to remove the blind plate to open the slot-type pipe interface 2 according to specific needs, thus providing high adaptability.

[0044] Optionally, the well body 1 and the slot-type pipe interface 2 are an integrated structure formed by a single mold or casting; or, the well body 1 is formed by splicing at least two modules, at least one module is provided with a slot-type pipe interface 2, and each module provided with a slot-type pipe interface 2 and the slot-type pipe interface 2 provided on the module are an integrated structure formed by a single mold or casting. According to requirements, the well body 1 and the slot-type pipe interface 2 are an integrated structure formed by a single mold or casting, which can make the well body 1 have strong structural strength and strong pressure-bearing capacity. In other embodiments, the well body 1 can be spliced ​​by two modules, each module is provided with a slot-type pipe interface 2, and the module and the slot-type pipe interface 2 thereon are an integrated structure formed by a single mold or casting.

[0045] like Figures 1 to 5As shown, the quick-install slot-type drainage well of this embodiment also includes a base plate 6, and the lower end of the well body 1 sits on the base plate 6. A pipe support seat 7 is provided on the top surface of the base plate 6 corresponding to the position of the slot-type pipe interface 2. A supporting groove 8 with an upward opening and a concave bottom is formed on the pipe supporting seat 7, and a space for placing the pipe to be installed is formed between the inner wall of the slot-type pipe interface 2 and the inner wall of the supporting groove 8.

[0046] After the pipe 13 is laid to the position of the pipe support seat 7, the pipe 13 is cut and placed in the supporting groove 8 of the pipe support seat 7, and the slot-type pipe interface 2 of the well body 1 is aligned with the pipe 13 and lowered so that the well body 1 is stuck on the pipe. The lower end of the well body 1 and the bottom plate 6 are sealed together by adhesive. At this time, the pipe is located between the inner wall of the slot-type pipe interface 2 and the inner wall of the supporting groove 8 to form a pipe placement space, which can then be backfilled. After backfilling, the sealing material is poured between the inner wall of the slot-type pipe interface 2 and the outer wall of the pipe to seal the installation gap between the outer wall of the pipe and the slot-type pipe interface 2 and the bottom plate 6. That is, by setting the bottom plate 6, there is no need to pour concrete into the well body 1 to exceed or meet the technical requirements of the concrete cushion layer, which reduces the on-site construction project links. Each link is completed in a visible state, the quality of the construction links is easy to control, which can speed up the overall construction project and also ensure the quality of the overall project.

[0047] In addition, the provision of the pipe support seat 7 further reduces the installation gap between the outer wall of the pipe and the slot-type drainage well. The sealing material injected from the sealing material injection port 3 can better seal the installation gap between the pipe and the slot-type drainage well. At the same time, the provision of the bottom plate 6 can increase the paving area of ​​the well foundation pit cushion layer in unstable geological conditions. While the cushion layer is being poured, the well bottom plate 6 is cast into the concrete cushion layer, exposing the upper surface of the bottom plate 6. The well body 1 and pipe are then installed according to the above-mentioned construction method. This can provide the well body 1 with a more stable well foundation, making the operation of the entire sewage system more stable.

[0048] like Figure 1 、 Figure 2 、 Figure 3 and Figure 5 As shown, a pipe supporting insert 9 is installed on the top of the pipe supporting seat 7 corresponding to the position of each sealing material rib 4, and the bottom of the pipe supporting insert 9 corresponding to the position directly above the supporting groove 8 is in contact with or close to the inner wall of the supporting groove 8. A downwardly concave semicircular pipe placement groove is provided on the top of the pipe supporting insert 9. The pipe supporting insert 9 is in contact with or close to the corresponding sealing material rib 4, and a circular or approximately circular pipe installation space is formed between the projections of the sealing material rib 4 and the pipe supporting insert 9 along the length direction of the slot-type pipe interface 2.

[0049] When the pipe is in the groove of the well body 1, the pipe support plate 9 is fixed on the well body 1, and the pipe support plate 9 is fixed on the well body 1. When the pipe is in the groove of the well body 1, the pipe support plate 9 is fixed on the well body 1, and the pipe support plate 9 is fixed on the well body 1. When the pipe is in the groove of the well body 1, the pipe support plate 9 is fixed on the well body 1. When the pipe is in the groove of the well body 1, the pipe support plate 9 is fixed on the well body 1. When the pipe is in the groove of the well body 1, the pipe support plate 9 is fixed on the well body 1

[0050] In addition, since the pipe support plug-in plate 9 and the pipe support seat 7 are inserted and installed together, the pipe support plug-in plate 9 with pipe placement grooves of different radii can be prefabricated in advance, and the appropriate pipe support plug-in plate 9 can be selected according to the outer diameter of the actually installed pipe. It has strong applicability. In particular, when the installed pipe is a corrugated pipe, the inner ring wall of the pipe placement groove and the sealing material retaining edge 4 can be respectively inserted into the trough on the outside of the corrugated pipe to position the corrugated pipe and prevent it from being offset from the well body 1 during installation.

[0051] like Figures 1 to 5 As shown, a concave water flow trough 11 parallel to the length direction of the supporting groove 8 is provided on the top surface of the bottom plate 6 corresponding to the position of the pipe support seat 7, and the inner wall of the concave water flow trough 11 is a circular arc surface, and a mounting groove 12 is provided on the top surface of the bottom plate 6. The bottom end of the well body 1 and the bottom end of the slot-type pipe interface 2 are both seated in the mounting groove 12, and the pipe support seat 7 is located in the mounting groove 12.

[0052] According to the needs, the recessed water flow trough 11 is higher than the supporting trough. During installation, the height of the recessed water flow trough is higher than or flush with the height of the inner wall of the bottom of the pipe. The setting of the water flow trough further accelerates the flow rate of sewage, avoids clogging inside the well body 1, reduces the number of maintenance times for the user, and reduces maintenance costs. An installation groove 12 is provided on the bottom plate 6, and the lower end of the well body 1 sits in the installation groove 12. Injecting adhesive into the installation groove 12 can seal the installation gap between the well body 1 and the bottom plate 6, further improving the installation efficiency and ensuring the sealing effect between the well body 1 and the bottom plate 6.

[0053] 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.
