Description

Technical Field

[0001] This utility model relates to the field of drainage technology, and in particular to a seepage prevention structure for water supply and drainage in building engineering. Background Technology

[0002] In today's rapidly developing construction engineering field, water supply and drainage systems are one of the core infrastructures that ensure the normal operation of buildings and the quality of life for residents, and their importance is self-evident. With the acceleration of urbanization and the continuous innovation of building technology, buildings are showing significant characteristics such as diversified functions, complex structures, and large scale. New types of buildings, such as large transportation hubs, super high-rise intelligent buildings, and integrated medical facilities, are constantly emerging, which brings unprecedented challenges to the water supply and drainage systems of building engineering.

[0003] On the one hand, different functional areas have vastly different requirements for water quality, quantity, pressure, drainage methods, and treatment, necessitating highly flexible and precisely adaptable water supply and drainage systems. On the other hand, increasing societal focus on building energy conservation, environmental protection, and sustainable development compels water supply and drainage systems to fully consider the rational use of water resources, efficient energy conservation, and minimal environmental impact throughout their entire lifecycle, from design and material selection to construction and operation management. Simultaneously, the wave of intelligentization is sweeping the construction industry. Leveraging cutting-edge technologies such as the Internet of Things, big data, and artificial intelligence to achieve intelligent monitoring, automatic control, and remote management of water supply and drainage systems has become a key development direction for improving system operating efficiency, reducing maintenance costs, and ensuring safe and stable water supply and drainage. In this complex and diverse context, building engineering water supply and drainage technology is continuously breaking through traditional limitations, making great strides towards integration, intelligence, and green development.

[0004] Patent document CN215669878U discloses a seepage-proof structure for water supply and drainage pipes in building engineering, including a water supply and drainage pipe, a seepage-proof sleeve, a float, and a pumping pipe. A limit plate is installed on the outer wall of the water supply and drainage pipe, and an installation box is installed on the right side wall of the drainage pipe. Conductive plates are symmetrically arranged on the left and right side walls of the inner cavity of the installation box via springs. Two conductive plates are attached to each other, and wires are installed on the other side of each conductive plate. One end of one of the wires is connected to a battery. When there is a large amount of seepage between the water supply and drainage pipe and the seepage-proof sleeve, the float raises the buoy rod, at which point the conductive sleeve is positioned between the two conductive plates. This allows the battery to be connected to a pump via wires, and the seepage is discharged through the pumping pipe. When the water level drops, the float lowers the buoy rod, and the insulating sleeve is positioned between the two conductive plates. Disconnecting the power supply to the pump stops its operation, achieving automatic discharge, which is convenient and quick.

[0005] As in the prior art of the aforementioned patent, the aforementioned anti-seepage sleeve discharges water through a water pump. However, the device does not consider how to handle the water after it has been pumped out. Furthermore, the water pump, conductive sheet, and battery require regular maintenance, resulting in high maintenance costs. Utility Model Content

[0006] The purpose of this utility model is to provide a seepage prevention structure for water supply and drainage in building engineering, so as to solve the above-mentioned shortcomings in the prior art.

[0007] To achieve the above objectives, the present invention adopts the following technical solution: a seepage prevention structure for water supply and drainage in building engineering, comprising two drainage pipes, which are connected by a flange connection assembly, and a seepage prevention sleeve is fitted at the connection point of the two drainage pipes. A sealing element is fixedly installed between the seepage prevention sleeve and the two drainage pipes, and a return pipe is installed between the seepage prevention sleeve and one of the drainage pipes.

[0008] As a further description of the above technical solution: an absorbent cotton layer is fixedly installed inside the seepage-proof sleeve. The absorbent cotton layer has a cavity and a through groove. The cavity is opened at the flange connection assembly, and the through groove is opened on one side of the cavity and connected to the return pipe.

[0009] As a further description of the above technical solution: the return pipe includes a discharge pipe, a bend pipe and an inlet pipe. The discharge pipe is connected and installed at the bottom end of the seepage-proof sleeve. The inlet pipe is disposed inside one of the drainage pipes and is parallel to the water flow direction. The bend pipe is used to connect the inlet pipe and the discharge pipe.

[0010] As a further description of the above technical solution: the flange connection assembly includes flanges fixedly installed on two drain pipes, and bolts and nuts are respectively provided on the two flanges, and the bolts and nuts are threadedly connected.

[0011] As a further description of the above technical solution: a liquid level alarm is fixedly installed at the bottom of the seepage-proof sleeve, the sensing end of the liquid level alarm is located inside the through groove, and a one-way valve is installed inside the bend of the return pipe.

[0012] As a further description of the above technical solution: the bottom end of the seepage-proof sleeve is connected to a drain pipe, and the bottom end of the drain pipe is threaded with a sealing cap.

[0013] This utility model provides a seepage-proof structure for water supply and drainage in building engineering. It has the following beneficial effects: by installing a seepage-proof pipe at the connection, when water seeps out from the connection of the drainage pipe, the seepage-proof sleeve can first catch the seepage water, and then let it flow into the return pipe, where it is first stored inside the return pipe. When there is a lot of seepage water, it can flow back into the drainage pipe through the return pipe, thereby realizing the return operation of seepage water.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0024] Reference Figure 1-5A seepage-proof structure for water supply and drainage in building engineering includes two drainage pipes 1 connected by a flange connection assembly. A seepage-proof sleeve 2 is fitted at the connection point of the two drainage pipes 1. A sealing element 3 is fixedly installed between the seepage-proof sleeve 2 and the two drainage pipes 1. A return pipe 4 is installed between the seepage-proof sleeve 2 and one of the drainage pipes 1. Seepage is prone to occur at the joint of the drainage pipes 1. By installing a seepage-proof pipe at the connection point, when water seeps out from the connection point of the drainage pipe 1, the seepage-proof sleeve 2 can first catch the seepage water and then let it flow into the return pipe 4, where it is first stored inside the return pipe 4. When there is a lot of seepage water, it can flow back into the drainage pipe 1 through the return pipe 4, thereby realizing the return operation of the seepage water.

[0025] As a preferred technical solution in this embodiment, an absorbent cotton layer 8 is fixedly installed inside the seepage-proof sleeve 2. The absorbent cotton layer 8 has a cavity 9 and a through groove 10 respectively. The cavity 9 is opened at the flange connection assembly, and the through groove 10 is opened on one side of the cavity 9 and connected to the return pipe 4. The absorbent cotton layer 8 can absorb the seepage water, slow down the seepage speed, and increase the timeliness of emergency repairs.

[0026] As a preferred technical solution of this embodiment, the return pipe 4 includes a discharge pipe 401, a bend pipe 402, and an inlet pipe 403. The discharge pipe 401 is connected and installed at the bottom end of the seepage-proof sleeve 2. The inlet pipe 403 is disposed inside one of the drain pipes 1 and is parallel to the water flow direction. The bend pipe 402 is used to connect the inlet pipe 403 and the discharge pipe 401. The water flowing into the return pipe 4 is discharged through the discharge pipe 401, enters the bend pipe 402, and then enters the inlet pipe 403, thereby realizing the return flow into the drain pipe 1.

[0027] As a preferred technical solution of this embodiment, the flange connection assembly includes flanges 11 fixedly installed on two drain pipes 1, and bolts 13 and nuts 12 are respectively provided on the two flanges 11, and the bolts 13 and nuts 12 are threadedly connected.

[0028] As a preferred technical solution in this embodiment, a liquid level alarm 5 is fixedly installed at the bottom of the seepage-proof sleeve 2. The sensing end of the liquid level alarm 5 is located inside the through groove 10. A one-way valve 16 is installed inside the bend 402 of the return pipe 4. The liquid level alarm 5 can sense the amount of water seeping out of the seepage-proof sleeve 2 and send an alarm signal to the outside, so that maintenance personnel can perform maintenance on time. The one-way valve 16 ensures that water can only flow in one direction from the return pipe 4 into the drain pipe 1.

[0029] It is worth mentioning that the liquid level alarm 5 is existing technology, and how to disassemble the anti-seepage sleeve 2 and how to repair it are not problems that this utility model needs to solve, so they will not be described in detail.

[0030] As a preferred technical solution in this embodiment, a drain pipe 6 is connected to the bottom end of the seepage-proof sleeve 2, and a sealing cap 7 is threaded onto the bottom end of the drain pipe 6; by opening the sealing cap 7, the water inside the seepage-proof sleeve 2 can be drained, which facilitates subsequent maintenance.

[0031] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
