Description

Technical Field

[0001] The present application relates to the technical field of water supply and drainage for construction projects, and in particular to a segmented drainage pipe structure for building construction. Background Art

[0002] With the continuous emergence of high-rise buildings, the importance of their drainage systems has become increasingly prominent. Traditional drainage pipes mostly adopt integrated or simple connection methods. When facing high-rise buildings, due to the characteristics of high floors, large water volume, and high water pressure, problems such as poor drainage, leakage at connections, and difficult maintenance are prone to occur. Therefore, how to improve the efficiency and stability of high-rise building drainage systems has always been a research focus in this field.

[0003] Conventional solutions include increasing the pipe diameter to increase drainage volume, using pipe materials that are more resistant to high pressure, and strengthening the sealing of joints. Although these methods can improve the drainage effect to a certain extent, there are still some shortcomings. For example, increasing the pipe diameter will take up more building space and the cost is relatively high; high-pressure resistant materials are often expensive and may not be able to meet the drainage needs of all high-rise buildings; although strengthening the sealing of joints can reduce leakage, there is still a certain risk of leakage under the action of long-term high-pressure water flow. In summary, the defects of the existing technical solutions mainly lie in the failure to combine the characteristics of high-rise buildings well for targeted design, resulting in difficulty in significantly improving drainage efficiency and stability, and the maintenance cost is also high.

[0004] To this end, the present application provides a segmented drainage pipe structure for building construction. Utility Model Content

[0006] To achieve the above-mentioned objectives, the present application provides the following technical solutions: a segmented drainage pipe structure for building construction, comprising a pipe body, the pipe body comprising several groups of pipe ends, two groups of first flanges fixedly installed on the outer ring of the pipe end, and connecting parts fixedly installed at both ends of the pipe end, the cross-section of the connecting part is trapezoidal, a connecting piece is connected between the two groups of pipe ends, connecting grooves matching the connecting part are provided on both sides of the connecting piece, two groups of second flanges are fixedly installed on the outer ring of the connecting piece, bolts are connected between the connecting grooves and the first flanges, and the small-mouth end of the connecting part is close to the connecting piece, a protective fastener is arranged between the pipe end and the connecting piece, and two groups of composite rubbers are arranged on the inner ring of the protective fastener, and the interior of the two groups of composite rubbers are filled with water-swellable glue.

[0007] By adopting the above technical solution, during installation, multiple pipe ends are first arranged in the order in which they need to be connected, and then a connector is placed between adjacent pipe ends, and the connecting groove of the connector is aligned with the connecting portion of the pipe end. Since the cross-section of the connecting portion is trapezoidal, it is convenient for the connecting portion to be inserted into the connector, thereby improving the connection efficiency. Then, a composite rubber is placed between the connector and the pipe end. The water-swelling rubber can automatically expand and fill the gap under the action of high-pressure water flow, thereby ensuring the sealing of the connection. The connecting groove and the first flange are fastened together by bolts to achieve the connection between the connector and the pipe end, which is convenient for installation and disassembly. Finally, the entire drainage pipe system is pressure tested to ensure that no leakage occurs. Among them, since the pipe body is composed of several groups of pipe ends, the length and diameter of each section can be flexibly adjusted according to actual needs, which is conducive to better adapting to the drainage needs of high-rise buildings and reducing occupied space. At the same time, the stable connection between the connecting groove and the second flange and the water-swelling rubber make the connection have better stability and sealing, effectively preventing leakage.

[0008] As a preferred technical solution of the present application, guide grooves are provided inside the plurality of groups of pipe ends. The guide grooves are distributed in a spiral shape, and the depth of the guide grooves gradually increases along the direction of water flow.

[0009] By adopting the above technical solution, the guide grooves are distributed in a spiral shape, and the groove depth of the guide grooves gradually increases along the direction of water flow. Such a design can effectively guide the water flow in a spiral shape, increase the contact area between the water flow and the inner wall of the pipe, and thus improve the drainage efficiency.

[0010] As a preferred technical solution of the present application, the protective fastener includes two groups of protective shells, which are respectively installed on the outer walls of the two groups of composite rubbers. Both ends of the protective shells are fixedly connected with connecting parts, and a screw is threadedly connected between the two adjacent groups of connecting parts.

[0011] By adopting the above technical solution, two sets of adjacent connecting parts are fixed by screws, and the protective shell is used to protect the composite rubber from corrosion by the external environment.

[0012] As a preferred technical solution of the present application, an inspection pipe is fixedly connected to one side of the pipeline end, and an inspection cover is threadedly connected to one end of the inspection pipe away from the pipeline end.

[0013] By adopting the above technical solution, the inspection cover is threadedly connected to the inspection pipe, which makes it easy to disassemble the inspection cover and facilitates the staff to inspect and repair the inside of the pipeline end through the inspection pipe.

[0014] As a preferred technical solution of the present application, two groups of valves are installed inside the tube body, and the two groups of valves are respectively located at the inlet and outlet of the tube body.

[0016] As a preferred technical solution of the present application, a plurality of groups of anti-slip strips are fixedly installed on the outer ring of the connecting member, and the anti-slip strips are evenly distributed along the outer ring of the connecting member.
