Description

Technical Field

[0001] This utility model relates to the technical field of waterproof inspection wells for heating pipelines, specifically a waterproof inspection well for heating pipelines. Background Technology

[0002] Since the introduction of prefabricated insulated direct-buried heating technology in my country in the late 1970s, it has been rapidly promoted in the country's heating industry and has gradually replaced underground pipe trench laying. With the continuous research and development of insulation structures and materials for direct-buried heating pipelines, direct-buried laying of high-temperature steam pipelines has also been gradually realized. Inspection chambers for valves, axial compensators, and drainage devices in various sections of the pipeline network must also be waterproofed to prevent groundwater from seeping into the chambers and corroding valves, pressure reducers, compensators, and other pipe fittings and their insulation layers. Direct-buried heating pipelines require strict waterproofing performance. However, the outer protective layer of direct-buried heating pipelines has a certain degree of elasticity, which makes waterproofing at pipe penetration points in the manholes ineffective, easily leading to groundwater infiltration. Furthermore, direct contact between the pipe and the wall at the pipe penetration point causes heat loss, which is inconsistent with the goals of building a modern energy-saving society. The space reserved for pipe penetrations also poses significant difficulties for waterproofing and drainage construction.

[0003] The existing heating pipeline waterproof inspection wells are constructed with brick-concrete structures. These structures have numerous construction joints, most of which lack waterproofing measures. The existing waterproofing measures consist of simply applying mortar mixed with waterproofing agent to the inner surface of the well walls. This waterproof mortar is only suitable for areas with low soil moisture around the well and has a short service life and poor waterproofing effect. Therefore, there is an urgent need to design a new type of waterproof inspection well for heating pipelines to solve these problems. Summary of the Invention

[0004] The purpose of this utility model is to provide a waterproof inspection well for heating pipelines, in order to solve the problems mentioned in the background art regarding the existing waterproof inspection wells for heating pipelines. The original heating well chamber structure adopts a brick-concrete structure, which has many construction joints and most of the construction joints are not waterproofed. The waterproofing measures for the well chamber are simply to apply mortar mixed with waterproofing agent to the inner surface of the well wall. The waterproof mortar is only suitable for places with low soil moisture around the well chamber and has a short service life and poor waterproofing effect.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a waterproof inspection well for a heating pipeline, comprising: a main well chamber, wherein a waterproof structure is provided inside the main well chamber, and a main and auxiliary well structure is provided outside the main well chamber. The waterproof structure includes a heating pipeline, which is installed through the main well chamber. A water-stop sleeve is installed inside the main well chamber, and a flexible sealing ring is provided at the connection between the water-stop sleeve and the main well chamber. The heating pipeline is sleeved inside the water-stop sleeve, and a flexible sealing ring is provided at the connection between the water-stop sleeve and the heating pipeline.

[0006] Preferably, the exterior of the main well chamber is provided with SBS waterproof membrane.

[0007] Preferably, the main well chamber has an installation groove at its upper end, a well cover is installed at the upper end of the installation groove, a handle is fixedly connected to the bottom end of the well cover, and a rubber ring is fixedly installed at the upper end of the installation groove.

[0008] Preferably, a handle is fixedly connected to the upper end of the manhole cover.

[0009] Preferably, the main and auxiliary well structure includes an auxiliary well chamber located outside the main well chamber. An exhaust pipe is installed outside the heating pipe, with the end of the exhaust pipe furthest from the heating pipe installed inside the auxiliary well chamber. A pipe valve is installed on the heating pipe.

[0010] Preferably, a drainage pipe is fixedly connected to the outer wall of the auxiliary manhole.

[0011] Compared with the prior art, the beneficial effects of the present invention are:

[0012] 1. This waterproof inspection well for heating pipelines is equipped with a waterproof structure. A water-stop steel plate is installed at the joints of the main well chamber, preventing water seepage that can easily occur when using brick-concrete well chambers with waterproof mortar. Water-stop sleeves are installed where the heating pipes pass through, and all connections are sealed with flexible sealing materials to prevent water from the surrounding area from seeping into the main well chamber. SBS waterproof membrane is installed on the bottom slab and side walls of the main well chamber to prevent water from the surrounding soil from seeping into the main well chamber. An inner cover is added to the bottom of the trench on the main well chamber to prevent groundwater from flowing in. This design effectively prevents rainwater, groundwater, and seepage from the surrounding area from entering the main well chamber. This design ensures that when the waterproof inspection well for heating pipelines is in use, it effectively prevents water from the surrounding area from seeping into the main well chamber and causing damage, avoiding corrosion of valves, pressure reducers, compensators, and other pipe fittings and their insulation layers, thus improving the practicality and waterproofing effect of the device.

[0013] 2. This waterproof inspection well for heating pipelines features a main and auxiliary well structure. When using this type of inspection well, a main and auxiliary well design is employed. An auxiliary well chamber is located outside the main well chamber. The heating pipes and valves are installed inside the main well chamber, while the vent pipe is installed inside the auxiliary well chamber. When the valves are opened to release air, a large amount of water is generated. The vent pipe then introduces the released air into the auxiliary well chamber, where the water remains. A submersible pump is used to remove the water from the auxiliary well chamber, preventing water accumulation in the main well chamber. A drainage pipe conveniently removes the accumulated water from the auxiliary well chamber. This design, employing a main and auxiliary well configuration, introduces the water generated by the venting of the water-stop sleeve into the auxiliary well chamber, preventing corrosion of valves, pressure reducers, compensators, and other fittings and their insulation layers inside the main well chamber. This improves the practicality and protective properties of the device. Attached Figure Description

[0020] Please see Figure 1-4 One embodiment provided by this utility model:

[0021] A waterproof inspection well for a heating pipeline includes: a main well chamber 111, a waterproof structure 2 installed inside the main well chamber 111, and a main and auxiliary well structure 3 installed outside the main well chamber 111. The waterproof structure 2 includes a heating pipeline 211, which runs through the main well chamber 111. A water-stop sleeve 212 is installed inside the main well chamber 111, and a flexible sealing ring is provided at the connection between the water-stop sleeve 212 and the main well chamber 111. The heating pipeline 211 is fitted inside the water-stop sleeve 212. A flexible sealing ring is provided at the connection between the water-stop sleeve 212 and the heating pipe 211. With this design, when using the waterproof inspection well of the heating pipe, a water-stop steel plate is installed at the joint of the main well chamber 111, which can avoid the phenomenon of water seepage at the joint that is easy to occur when applying waterproof mortar mixed with waterproof agent to the brick-concrete well chamber. In addition, a water-stop sleeve 212 is installed at the passage of the heating pipe 211, and the connection is sealed with flexible sealing material to prevent water around the well chamber from seeping into the main well chamber 111 along with the heating pipe 211.

[0022] Furthermore, an SBS waterproof membrane 213 is installed on the outside of the main well chamber 111. Through this design, by installing the SBS waterproof membrane 213 on the bottom plate and side walls of the main well chamber 111, water from the surrounding soil can be prevented from seeping into the main well chamber 111.

[0023] Furthermore, an installation groove 214 is provided at the upper end of the main well chamber 111, and a well cover 215 is installed at the upper end of the installation groove 214. A handle 216 is fixedly connected to the bottom end of the well cover 215, and a rubber ring is fixedly installed at the upper end of the installation groove 214. Through this design, by adding an inner cover 217 at the bottom end of the installation groove 214 on the main well chamber 111, the flow of ground water into the main well chamber 111 is prevented, thereby completely solving the problem of rainwater from the well, ground water, and seepage water around the main well chamber 111 entering the interior of the main well chamber 111.

[0024] Furthermore, a handle 216 is fixedly connected to the upper end of the manhole cover 215. With this design, the handle 216 fixedly connected to the upper end of the manhole cover 215 can be easily opened.

[0025] Furthermore, the main and auxiliary well structure 3 includes an auxiliary well chamber 311, which is located outside the main well chamber 111. An exhaust pipe 313 is installed outside the heating pipe 211, and the end of the exhaust pipe 313 away from the heating pipe 211 is installed inside the auxiliary well chamber 311. A pipe valve 312 is installed on the heating pipe 211. With this design, when using the waterproof inspection well of the heating pipe, a main well and auxiliary well design is adopted. The auxiliary well chamber 311 is set outside the main well chamber 111, the heating pipe 211 and the pipe valve 312 are installed inside the main well chamber 111, and the exhaust pipe 313 is installed inside the auxiliary well chamber 311. When the pipe valve 312 is opened to release air, a large amount of water will be generated. At this time, the exhaust pipe 313 will introduce the released air into the auxiliary well chamber 311. The generated water is stored inside the auxiliary well chamber 311. The water in the well chamber is pumped away by a submersible pump, so that water will not accumulate inside the main well chamber 111.

[0026] Furthermore, a drain pipe is fixedly connected to the outer wall of the auxiliary well chamber 311. Through this design, the drain pipe can conveniently drain the water accumulated inside the auxiliary well chamber 311.

[0027] Working principle:

[0028] When using this waterproof inspection well for heating pipes, a water-stop steel plate is installed at the joint of the main well chamber 111 to avoid the phenomenon of water seepage at the joints that is prone to occur when applying waterproof mortar to brick-concrete well chambers. In addition, a water-stop sleeve 212 is installed at the penetration point of the heating pipe 211, and the connection is sealed with flexible sealing material to prevent water around the well chamber from seeping into the main well chamber 111 along with the heating pipe 211. By installing SBS waterproof membrane 213 on the bottom plate and side walls of the main well chamber 111, water from the surrounding soil can be prevented from seeping into the main well chamber 111. By installing an inner cover 217 at the bottom of the groove 214 on the main well chamber 111, ground water can be prevented from flowing into the main well chamber 111, thus completely solving the problem of rainwater from the well, ground water, and seepage water around the main well chamber 111 entering the main well chamber 111.

[0029] When using this waterproof inspection well for heating pipeline, a main well and auxiliary well design is adopted. An auxiliary well chamber 311 is set outside the main well chamber 111. The heating pipeline 211 and pipeline valve 312 are installed inside the main well chamber 111, and the vent pipe 313 is installed inside the auxiliary well chamber 311. When the pipeline valve 312 is opened to release air, a large amount of water will be generated. At this time, the vent pipe 313 will introduce the released air into the auxiliary well chamber 311. The water generated is stored inside the auxiliary well chamber 311. The water in the well chamber is then pumped away using a submersible pump, which will not cause water accumulation inside the main well chamber 111. The drain pipe can easily drain the water inside the auxiliary well chamber 311. The operation is then completed.
