Description

Technical Field

[0001] This invention relates to the field of municipal construction technology, and in particular to a construction device and method for connecting or repairing non-disruptive pipelines. Background Technology

[0002] With the continuous advancement of urbanization in my country, the scale of municipal drainage engineering construction is constantly expanding. To minimize the impact of upgrading existing municipal drainage pipelines on traffic, the environment, and the lives of surrounding residents, connecting existing pipelines to new drainage facilities is currently the main method for urban drainage system renovation. However, minimizing the impact of sewage leaks on the surrounding environment remains a significant construction challenge during the construction of connecting new drainage pipelines to existing ones, or during the repair of leaks in existing manholes and pipelines.

[0003] Construction work involving the connection of new drainage pipelines to existing drainage pipelines, as well as emergency repairs to existing manholes and pipelines, often employs methods such as sealing the manhole inlet, constructing temporary diversion wells, and pumping out accumulated water to create a dry working surface. However, this construction method has disadvantages such as occupying existing manhole space, poor sealing of existing pipelines, slow pumping out of accumulated water, significant impact on surrounding residents and the environment, and safety risks. Summary of the Invention

[0004] To overcome the shortcomings mentioned above, this invention aims to provide a construction device and method for connecting or repairing non-interrupted pipelines, which can effectively solve the problems of occupying existing manhole space, poor sealing effect of existing pipelines, slow drainage of accumulated water, interference with surrounding residents and the environment, and safety risks associated with the above construction methods.

[0005] To achieve the above objectives, the present invention provides a construction device for connecting or repairing non-interrupted flow pipelines, comprising:

[0006] A drainage pipe is installed that passes sequentially through a first pipe, a working chamber, and a second pipe. The first pipe is used to connect the upstream chamber and the working chamber, and the second pipe is used to connect the downstream chamber and the working chamber.

[0007] The sealing ring consists of a large end ring and a small end ring with an integrated coaxial design.

[0008] The first fastener and the second fastener, wherein the large end ring is detachably connected to the upstream end of the first pipe through the first fastener, and the small end ring is detachably connected to the inlet end of the drain pipe through the second fastener;

[0009] And a drainage assembly for draining water accumulated in the working chamber.

[0010] Furthermore, the end face of the large end ring near the small end ring abuts against the end face of the upstream end of the first pipe, and the outer wall of the large end ring is detachably connected to the outer wall of the upstream end of the first pipe through the first fastener.

[0011] The inlet end of the drain pipe is sleeved on the outer wall of the small end ring and is detachably connected via the second fastener.

[0012] Furthermore, it also includes a threading device for guiding the drainage pipe through the first pipe, the working chamber, and the second pipe in sequence.

[0013] Compared with the prior art, the present invention has at least the following advantages:

[0014] In use, firstly, the drainage pipe needs to be installed sequentially through the first pipe, the working chamber, and the second pipe; secondly, the inlet end of the drainage pipe is connected to the upstream end of the first pipe; finally, the accumulated water in the working chamber is drained, thus creating the required dry working environment in the working chamber, allowing for pipe network connection or repair work to be carried out. This invention, on the one hand, eliminates the need for temporary diversion wells during construction, reducing construction steps, improving construction efficiency, and causing no disturbance to surrounding residents or the environment, with no safety risks; on the other hand, it does not alter the flow of rainwater or sewage within the chamber and pipes, allowing the flow of rainwater or sewage within the chamber and pipes to be achieved without external force, offering energy-saving and environmentally friendly advantages; furthermore, because a drainage pipe is used for diversion, there is no need to seal the pipes during construction, solving the problems of excessive water flow, difficulty in sealing, and difficulty in pumping, effectively addressing the environmental pollution problem of sewage leakage.

[0015] This invention is highly operable, ensuring construction efficiency and quality, and is suitable for promotion and application. Its simple structure allows for quick and easy installation and dismantling, and it is recyclable and reusable, making it highly adaptable and meeting current societal requirements for green construction.

[0016] Another aspect of the present invention provides a construction method for connecting or repairing non-interrupted flow pipelines, characterized by comprising the following steps:

[0017] The drainage pipe is sequentially passed through the first pipe, the working chamber, and the second pipe. The first pipe is used to connect the upstream chamber and the working chamber, and the second pipe is used to connect the downstream chamber and the working chamber.

[0018] Connect the inlet end of the drain pipe to the upstream end of the first pipe;

[0019] Drain the accumulated water from the working well chamber;

[0020] Pipeline connection or repair work is carried out in the working chamber.

[0021] The drain pipe is removed from the first pipe, the working chamber, and the second pipe.

[0022] Furthermore, connecting the inlet end of the drain pipe to the upstream end of the first pipe includes: using a sealing ring to detachably connect the upstream end of the first pipe and the inlet end of the drain pipe respectively.

[0023] Furthermore, the sealing ring includes a large end ring and a small end ring designed as an integral coaxial unit; connecting the water inlet end of the drain pipe to the upstream end of the first pipe includes: detachably connecting the small end ring to the water inlet end of the drain pipe through the second fastener, and detachably connecting the large end ring to the upstream end of the first pipe through the first fastener.

[0038] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0039] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0040] Reference Figure 1-6In this invention, the upstream well chamber 1, the working well chamber 2, and the downstream well chamber 3 are all existing well chambers, and the first pipe 4 and the second pipe 5 are both existing drainage pipes. The working well chamber 2 is connected to the upstream well chamber 1 through the first pipe 4, and the working well chamber 2 is connected to the downstream well chamber 3 through the second pipe 5. Rainwater or sewage exists in the upstream well chamber 1, the first pipe 4, the working well chamber 2, the second pipe 5, and the downstream well chamber 3. This invention provides a construction device for connecting or repairing non-interrupted pipelines, addressing the shortcomings of conventional construction methods. It is applied to connecting new drainage pipelines to existing drainage pipelines and to emergency repairs of leaks in existing well chambers and pipelines, enabling construction in a dry working environment in the working well chamber 2. The specific structure includes a drainage pipe 9, a sealing ring 6, a first fastener 10, a second fastener 11, and drainage components.

[0041] The drainage pipe 9 is installed sequentially through the first pipe 4, the working chamber 2, and the second pipe 5. The drainage pipe 9 is preferably a flexible hose, used to guide the accumulated water in the upstream chamber 1 into the downstream chamber 3 and to ensure that the accumulated water does not flow into the working chamber 2. The sealing ring 6 includes a large end ring 601 and a small end ring 602 with an integral design. The axis of the large end ring 601 and the axis of the small end ring 602 are on the same straight line. The large end ring 601 is detachably connected to the upstream end of the first pipe 4 by the first fastener 10, and the small end ring 602 is detachably connected to the water inlet end of the drainage pipe 9 by the second fastener 11. Both the first fastener 10 and the second fastener 11 are preferably clamp structures. The drainage assembly is used to drain the accumulated water in the working chamber 2. The drainage assembly is preferably a sewage pump.

[0042] Preferably, the outer diameter of the large end ring 601 is greater than the outer diameter of the upstream end of the first pipe 4, and the difference between the outer diameter of the large end ring 601 and the outer diameter of the upstream end of the first pipe 4 is 1cm-2cm. When connected, the end face of the large end ring 601 near the small end ring 602 abuts against the end face of the upstream end of the first pipe 4, and the outer wall of the large end ring 601 and the outer wall of the upstream end of the first pipe 4 are detachably connected by the first fastener 10. The outer diameter of the small end ring 602 is less than the inner diameter of the inlet end of the drain pipe 9. When connected, the inlet end of the drain pipe 9 is fitted onto the outer wall of the small end ring 602 and is detachably connected by the second fastener 11.

[0043] Optionally, the present invention further includes a threading device 7, which is used to guide the drainage pipe 9 through the first pipe 4, the working chamber 2, and the second pipe 5 in sequence.

[0044] In use, firstly, the tow line is sequentially passed through the downstream well chamber 3, the second pipe 5, the working well chamber 2, and the first pipe 4 using the threading device 7 before entering the upstream well chamber 1. The threading device 7 uses a threader to connect the outlet end of the drain pipe 9 to the tow line. The tow line guides the drain pipe 9 and sequentially passes through the first pipe 4, the working well chamber 2, and the second pipe 5. The connection between the tow line and the outlet end of the drain pipe 9 is then disconnected. Secondly, the first clamp 10 and the second clamp 11 are hoisted using the hoisting device 8. The worker uses the second clamp 11 to detachably connect the small end ring 602 to the inlet end of the drain pipe 9, and uses the first clamp 10 to detachably connect the large end ring 601 to the upstream end of the first pipe 4. This allows the water in the upstream well chamber 1 to flow into the downstream well chamber 3 through the drain pipe 9, ensuring that the water does not enter the working well chamber 2. The drainage assembly can quickly drain the water from the working well chamber 2, creating a dry working environment. Next, pipeline connection or repair work is carried out in the working chamber 2. Finally, after the pipeline connection or repair work is completed, the connection between the large end ring 601 of the first fastener 10 and the upstream end of the first pipeline 4 is released, and the connection between the small end ring 602 of the second fastener 11 and the inlet end of the drain pipe 9 is released. The drain pipe 9 is then taken out through the first pipeline 4, the working chamber 2 and the second pipeline 5 in sequence using the hoisting device 8. The sealing ring 6 is then taken out from the upstream chamber 1 to complete the construction work.

[0045] Compared with the prior art, the present invention has at least the following advantages:

[0046] On the one hand, this invention eliminates the need for temporary diversion wells during construction, reducing construction steps, improving efficiency, and preventing rainwater or sewage leakage. It also avoids any disturbance to surrounding residents and the environment, posing no safety risks. On the other hand, it does not alter the flow path of rainwater or sewage within the well chamber and pipes. The flow of rainwater or sewage within the well chamber and pipes can be achieved without the need for external force such as sewage pumps, offering advantages in energy conservation and environmental protection. Furthermore, because drainage pipes are used for diversion, there is no need to seal the pipes during construction, solving the problems of excessive water flow, difficulty in sealing, and pumping difficulties, effectively addressing the environmental pollution problem caused by sewage leakage.

[0047] This invention is highly operable, ensuring construction efficiency and quality, and is suitable for promotion and application. Its simple structure allows for quick and easy installation and dismantling, and it is recyclable and reusable, making it highly adaptable and meeting current societal requirements for green construction.

[0048] Reference Figure 7Another aspect of the present invention provides a construction method for non-interrupted pipeline connection or repair, comprising the following steps: A drainage pipe 9 is sequentially passed through a first pipe 4, a working chamber 2, and a second pipe 5, wherein the working chamber 2 is connected to the upstream chamber 1 via the first pipe 4, and the working chamber 2 is connected to the downstream chamber 3 via the second pipe 5; rainwater or sewage exists in the upstream chamber 1, the first pipe 4, the working chamber 2, the second pipe 5, and the downstream chamber 3; the inlet end of the drainage pipe 9 is connected to the upstream end of the first pipe 4, after which rainwater or sewage flows from the drainage pipe 9 through the working chamber and into the downstream chamber; the accumulated water in the working chamber 2 is drained using a drainage assembly, thereby creating a dry working environment in the working chamber 2; pipeline connection or repair work is carried out in the working chamber 2; the drainage pipe 9 is removed from the first pipe 4, the working chamber 2, and the second pipe 5, and the water flow resumes its original path from the upstream chamber 1 into the working chamber 2, thus completing the drainage pipeline connection.

[0049] It should be noted that, in the above construction method, the drainage pipe 9 is preferably a flexible hose, and the drainage component is preferably a sewage pump.

[0050] Preferably, connecting the inlet end of the drain pipe 9 to the upstream end of the first pipe 4 includes: using a sealing ring 6 to detachably connect the upstream end of the first pipe 4 and the inlet end of the drain pipe 9 respectively.

[0051] Optionally, the sealing ring 6 includes a large end ring 601 and a small end ring 602 with an integrally molded design, the axis of the large end ring 601 and the axis of the small end ring 602 being on the same straight line. Connecting the water inlet end of the drain pipe 9 to the upstream end of the first pipe 4 includes: detachably connecting the small end ring 602 to the water inlet end of the drain pipe 9 by means of a second fastener 11, and detachably connecting the large end ring 601 to the upstream end of the first pipe 4 by means of a first fastener 10. Both the first fastener 10 and the second fastener 11 preferably use a clamp structure, and both the first fastener 10 and the second fastener 11 are installed using an excavator in conjunction with manual labor.

[0052] Preferably, the drain pipe 9 is sequentially passed through the first pipe 4, the working chamber 2, and the second pipe 5, including: using a threading device 7 to guide the drag line sequentially through the downstream chamber 3, the second pipe 5, the working chamber 2, and the first pipe 4 before entering the upstream chamber 1. The threading device 7 is a threader. The drain pipe 9 outlet end is connected to the drag line. The drag line guides the drain pipe 9 and sequentially passes through the first pipe 4, the working chamber 2, and the second pipe 5. After completion, the connection between the drag line and the drain pipe 9 outlet end is disconnected.

[0053] Specifically, the pipeline connection operation is carried out in the working chamber 2, including: connecting the first newly built pipeline (not shown in the figure) to the reserved opening or the broken opening in the working chamber 2, and sealing the wall of the working chamber 2 at the connection between the first newly built pipeline and the working chamber 2. After the first newly built pipeline is connected to the new drainage system, the first newly built pipeline is backfilled.

[0054] Optionally, pipeline repair work is carried out in the working chamber 2, including: removing the damaged pipeline connected to the working chamber 2 and replacing it with a second newly built pipeline (not shown in the figure), sealing the wall of the working chamber 2 at the connection between the second newly built pipeline and the working chamber 2, and backfilling the second newly built pipeline.

[0055] It should be understood that the damaged pipe, the first pipe 4, and the second pipe 5 are connected to the working chamber 2. The working chamber 2 is connected to another chamber through the damaged pipe. By using the drainage pipe 9 to introduce the accumulated water in the upstream chamber 1 into the downstream chamber 3, a dry working environment can be achieved in the working chamber 2, and the damaged pipe can be replaced.

[0056] Preferably, removing the drain pipe 9 from the first pipe 4, the working chamber 2, and the second pipe 5 includes: disconnecting the connection between the first fastener 10 and the large end ring 601 and the upstream end of the first pipe 4; disconnecting the connection between the second fastener 11 and the small end ring 602 and the inlet end of the drain pipe 9; removing the drain pipe 9 sequentially through the first pipe 4, the working chamber 2, and the second pipe 5; and removing the sealing ring 6 from the upstream chamber 1.
