Description

Technical Field

[0001] This utility model relates to the field of underground pipeline construction technology, and in particular to a construction device for water-carrying operation in a manhole flow channel. Background Technology

[0002] In municipal engineering, underground pipe networks, and drainage systems, inspection wells serve as access points for the pipe network, providing vertical access for pipe maintenance, dredging, and equipment replacement.

[0003] Inspection well chutes are typically semi-circular or U-shaped structures located at the bottom of the inspection well. They are used to reduce the resistance of water flow at pipe junctions and intersections, prevent the formation of eddies and stagnant water zones, and improve drainage efficiency.

[0004] However, during the construction of manhole chutes, it is usually necessary to dewater or block the upstream pipeline network, and then use formwork support for pouring. Construction with water shut off is not only costly, but also inefficient due to the alternation of drainage and construction, and it is not conducive to the concrete chute pouring and forming, resulting in unsatisfactory performance. Utility Model Content

[0005] The purpose of this utility model is to solve the above-mentioned problems by providing a construction device for manhole channel construction with water flow that does not require drainage construction, is easy to install and disassemble, and is conducive to the casting and forming of concrete channel.

[0019] The present invention will now be described in further detail with reference to the accompanying drawings. The drawings are simplified schematic diagrams, illustrating only the basic structure of the present invention, and therefore only show the components relevant to the present invention.

[0020] Please refer to Figure 1-4 A construction device for water-carrying operation in a manhole includes a manhole 1. On opposite sides of the manhole 1, there are original well pipes 2 that connect to the manhole. The ends of the original well pipes 2 are flush with the inner wall of the manhole 1. A detachable guide pipe 3 is provided between the two original well pipes 2. Concrete 5 is provided below the guide pipe 3. The height of the concrete 5 is flush with the axis of the original well pipe 2.

[0021] Since there is water flow inside the original well pipe 2, a guide pipe 3 is installed in order to pour concrete 5 to form a flow channel 6. When in use, both ends of the guide pipe 3 are inserted into the corresponding original well pipe 2. After insertion, the water flow in the original well pipe 2 flows through the guide pipe 3. At this time, the water in the inspection well is drained to pour concrete 5 or mortar masonry. After it solidifies, the guide pipe 3 is disassembled to form the flow channel 6; thus realizing the construction operation of the flow channel with water.

[0022] In this embodiment, the guide tube 3 has a cut 31 along its own length direction, wherein the cut 31 occupies 1 / 6 of the cross-section of the guide tube 3.

[0023] The setting of the cut 31 allows the guide pipe 3 to be matched with the original well pipe 2 of different diameters, thus increasing the range of applications. In addition, the setting of the cut 31 also facilitates disassembly. During disassembly, the guide pipe 3 can be squeezed at the cut 31, which allows the guide pipe 3 to be quickly separated from the concrete 5.

[0024] In order to make the guide pipe 3 fit with the original well pipe 2, the inner walls of the guide pipe 3 are respectively provided with annular telescopic airbags 4. The annular telescopic airbags 4 push the guide pipe 3 to contact the inner wall of the original well pipe 2.

[0025] The annular telescopic airbag 4 is provided with an inflation / deflation port 41, and a water inlet 42 is provided on one side of the inflation / deflation port 41.

[0026] After inflation at the inflation / deflation port 41, the annular telescopic airbag 4 expands and extends, thereby pushing the surrounding guide pipe 3 outward, so that the outer wall of the guide pipe 3 is tightly attached to the inner wall of the original well pipe 2, thus isolating the water flow from the channel construction surface and allowing the water flow to pass through the guide pipe 3; when the water flow is small, the water flow enters the guide pipe 3 from the water outlet 42; when the water flow is large, the water flow passes over the annular telescopic airbag 4 and enters the guide pipe 3; therefore, regardless of the water flow size, channel construction with water can be achieved.

[0027] Similarly, when it is necessary to disassemble the guide pipe 3, release the air at the air inlet 41 to cause the annular telescopic airbag 4 to contract. At this time, the guide pipe 3 will no longer be tightly attached to the inner wall of the original well pipe 2, and it can be pulled out and disassembled.

[0028] In order to improve the sealing degree between the guide pipe 3 and the original well pipe 2, the guide pipe 3 is also provided with a neutral silicone sealing ring 32 on the outer wall at both ends. When the guide pipe 3 deforms and extends, the sealing ring 32 is clamped and deformed by the guide pipe 3 and the original well pipe 2 to improve the sealing effect.

[0029] When in use, first insert both ends of the guide pipe 3 into the corresponding original well pipe 2, so that the water in the original well pipe 2 flows through the guide pipe 3; at this time, pour concrete below the guide pipe 3 (inside the inspection well 1); after the concrete 5 solidifies, remove the guide pipe 3, and the removal of the guide pipe 3 forms a flow channel 6. The cross-section of the flow channel 6 is semi-circular, and its inner diameter is consistent with the inner diameter of the original well pipe 2; so that the water in the original well pipe 2 flows through the flow channel.

[0030] Based on the above embodiments, the guide pipe 3 is preferably made of UPVC pipe, which has good corrosion resistance.

[0031] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
