Description

Technical Field

[0001] The present application relates to the technical field of ground source heat pumps, and more specifically, to a pipeline fixing device and an underground pipe system. Background Art

[0002] The underground pipe system includes vertical buried pipes and horizontal buried pipes. The construction process is that after the vertical well is drilled, multiple groups of vertical buried pipes are installed in the well at intervals, and then horizontal buried pipes are used to connect the vertical buried pipes in series, and then they are connected to the heat pump unit after being aggregated.

[0003] In areas with good geology, horizontal trenches can be excavated after the vertical buried pipe construction is completed. After the horizontal trench is formed, 300mm of fine sand is laid in the horizontal trench, and then the water pipes are laid. After the horizontal buried pipes are connected to the vertical buried pipes, fine sand is used for backfilling. The fine sand covers the horizontal buried pipes by at least 200mm, and then the original soil is used for backfilling to zero or under the basement floor.

[0004] However, in areas with poor geology, such as construction sites with high groundwater levels, horizontal trench excavation can be difficult during construction. This can lead to mud backflow or trench collapse before the horizontal pipes are fully installed, preventing proper installation. Furthermore, in construction sites where mud is predominant, horizontal trench formation is difficult and backfill or basement floor pouring must be completed quickly. This places higher demands on the difficulty and timeliness of buried water pipe installation, which conventional installation solutions cannot meet.

[0005] Therefore, a pipeline fixing device and an underground pipe system are needed to solve the above problems. Utility Model Content

[0006] In view of this, the purpose of this application is to propose a pipeline fixing device and an underground pipe system to solve the problems existing in traditional technologies.

[0007] Based on the above purpose, the present application provides a pipeline fixing device, comprising:

[0008] At least two assembly layers are stacked, and fixing grooves are provided on at least one side surface of adjacent assembly layers, and the fixing grooves arranged opposite to each other enclose a cavity for accommodating the pipeline.

[0009] Optionally, a plurality of the fixing grooves are provided on each of the assembly layers, and the plurality of the fixing grooves are spaced apart in sequence along the width direction of the assembly layer, and each of the fixing grooves is provided through the length direction of the assembly layer.

[0010] Optionally, the assembly layer includes a first assembly layer and / or a second assembly layer, the fixing groove is provided on one side surface of the first assembly layer, and the fixing grooves are provided on both opposite side surfaces of the second assembly layer.

[0011] Optionally, a positioning structure is provided on the assembly layer.

[0012] Optionally, the positioning structure includes a positioning groove and a positioning connecting pin; the positioning groove and the fixing groove are both arranged on the same side of the assembly layer, and the opposite ends of the positioning connecting pin are respectively connected to the relatively arranged positioning grooves of adjacent assembly layers.

[0013] Optionally, a breaking structure is provided on the assembly layer, and the breaking structure is located between two ends of the assembly layer.

[0014] Optionally, the breaking structure and the assembled layer plate are an integrally formed structure.

[0015] The present application also provides an underground pipe system, comprising:

[0016] A plurality of pipe fixtures as described above;

[0018] Optionally, the connecting member includes a three-way connecting pipe, the two opposite ends of the three-way connecting pipe are respectively connected to the adjacent medium pipes, and the three ends are connected to the external pipeline through the third end.

[0019] In addition, optionally, the buried pipe system further comprises: an external fixing member, through which adjacent pipe fixing devices are fixed and integrated into an integral structure.

[0020] As can be seen from the above, the pipe fixing device and underground pipe system provided by the present application have the following advantages compared with the prior art: placing the pipe between the assembly layers can provide a fixing effect for the pipe, and during the construction process, the pipe will not be displaced, affecting the connection with other pipes; at the same time, relative to the shape of the pipe, it is easier to construct outside the assembly layer.

[0031] To make the objectives, technical solutions, and advantages of this application more clearly understood, the present application is further described below in conjunction with specific embodiments and with reference to the accompanying drawings. Identical parts are denoted by the same reference numerals. It should be noted that the terms "front," "rear," "left," "right," "up," and "down" used in the following description refer to directions in the accompanying drawings. The terms "inward" and "outward" refer to directions toward or away from the geometric center of a particular component, respectively.

[0032] Figure 1 This is a schematic diagram of a pipe fixing device used in a specific embodiment of the present application. Figure 2 for Figure 1 Exploded view of the pipe fixture shown. Figure 3 for Figure 2 A side view of the pipe fixture is shown. Figure 4 for Figure 2 A perspective view of the pipe fixture is shown. Figure 5 for Figure 2 The enlarged view of the assembled laminate is shown in FIG. Figures 1 to 5 As shown, the pipe fixing device includes at least two assembled layers 10 .

[0033] The pipe fixing device 100 includes at least two assembly layers 10, which are stacked. A fixing groove 11 is provided on at least one side surface of the adjacent assembly layers 10, and the oppositely arranged fixing grooves 11 enclose a cavity 12 for accommodating the pipe.

[0034] The pipe is placed in the cavity 12 formed by the fixing groove 11 of the adjacent assembly layer plates 10. A plurality of pipes can be assembled on the adjacent assembly layer plates, and the assembly layer plates and the pipes are placed at a designated position as an integral structure.

[0035] The aforementioned pipe fixing device, placed between the assembly panels, secures the pipes. During construction, the pipes do not shift, potentially impacting their connection to other pipes. Furthermore, given the pipe's shape, construction is easier outside the assembly panels. Even in areas with poor geology, rapid prototyping with the assembly panels prevents mud backflow or trench collapse, allowing for rapid backfill or pouring outside the assembly panels. The use of the pipe fixing device facilitates quick on-site connections, reduces protection requirements, shortens construction time, and streamlines construction steps.

[0036] In one embodiment of the present application, the pipe fixing device 100 includes a plurality of assembly layers 10, such as 5, and the plurality of assembly layers 10 are stacked in sequence. The assembly layers 10 have a fixing groove 11 on at least one side facing the adjacent assembly layer 10. For example, the top or bottom assembly layer can have a fixing groove 11 on only one side surface, and the assembly layer located in the middle can have a fixing groove 11 on both the upper and lower surfaces. The fixing grooves 11 on the two adjacent assembly layers 10 enclose a cavity 12 for accommodating the pipe.

[0037] During on-site construction, after the excavator has initially cleared the silt and formed the trench, the integrated pipe fixture 100 can be placed in place to achieve quick on-site connection. This eliminates the need for laying fine sand in the trench and backfilling it with fine sand for protection, significantly reducing construction time and steps. It also avoids situations where the trench is difficult to excavate and form, leading to mud backflow or trench collapse before the horizontal pipe is installed. By adopting the above-mentioned pipe fixture, the above-mentioned technical problems can be effectively solved, achieving quick on-site connection, reducing the difficulty of protection, shortening construction time, and saving construction steps.

[0038] The number, location, and arrangement of the fixing grooves on the assembly panels can be customized based on specific operating conditions. For longer and more numerous pipes, each assembly panel can optionally be equipped with multiple fixing grooves, spaced sequentially along the width of the panel, with each groove extending through the length of the panel. By customizing the location and shape of the fixing grooves, the assembly panels can be fully utilized, allowing more pipes to be integrated within a limited space.

[0039] In one embodiment of the present application, the assembly layer 10 can be manufactured and formed by an extrusion process, and the specifications, quantity and position of the fixing grooves 11 can be set according to different needs. For example, the assembly layer 10 with an extruded board factory prefabricated integral molding structure can be prefabricated on the assembly layer 10 according to different needs. The fixing grooves 11 can also be prefabricated in combination with the mainstream pipe specifications in the project. For example, the outer diameter of the de63PE (polyethylene, Polyethylene, abbreviated as PE) pipe is 63mm, and the diameter of the fixing groove 11 on the assembly layer 10 is 70mm. Each assembly layer 10 has a semicircular fixing groove 11 with a depth of 35mm. After the two assembly layers 10 are assembled, a cavity 12 with a diameter of 70mm can be formed. The de63PE pipe is wrapped in the cavity 12, and the assembled pipe fixing device 100 can form an integral structure. The pipe fixing device 100 can be applied to the horizontal buried pipe system in the ground source heat pump system, and can also be applied to the vertical buried pipe system.

[0040] The specifications, quantity and position of the fixing grooves 11 on each assembly layer 10 can be set according to different requirements. In one embodiment of the present application, there are multiple fixing grooves 11, and the sizes of the fixing grooves 11 can be the same, or different, or at least partially the same and partially different.

[0041] For example, each assembled layer 10 is provided with 8 fixing grooves 11, each fixing groove 11 has a diameter of 70 mm, and each assembled layer 10 has a semicircular fixing groove 11 with a depth of 35 mm. After assembling two assembled layers 10, a cavity 12 with a diameter of 70 mm can be formed. For another example, each assembled layer 10 is provided with 8 fixing grooves 11, wherein a portion of the fixing grooves 11 has a diameter of 70 mm and another portion of the fixing grooves 11 has a diameter of 80 mm. After assembling two assembled layers 10, a cavity 12 with a diameter of 70 mm and a cavity 12 with a diameter of 80 mm can be formed, thereby adapting to pipes of different diameters.

[0042] Optionally, the assembly layer 10 includes a first assembly layer and / or a second assembly layer. The first assembly layer has a fixing groove 11 on one surface, and the second assembly layer has fixing grooves 11 on both opposing surfaces. Typically, one first assembly layer is used at the top and bottom, and multiple second assembly layers are used in the middle. By combining different types of assembly layers, different assembly effects can be achieved to meet different assembly requirements.

[0043] In one embodiment of the present application, the number and size of the assembled layers 10 can be set according to different requirements. The number and specifications of the assembled layers 10 in each pipe fixture 100 can be prefabricated according to the requirements of different working conditions. For example, the assembled layers 10 at different positions can be respectively called cover plates, interlayer plates and bottom plates. Figure 2 ,by Figure 2 Taking the position in the figure as an example, the assembly layer 10a located at the top position is the first assembly layer, which can be called the cover plate, that is, the cover plate is the top of the pipe fixing device 100. The assembly layer 10c located at the bottom position is the first assembly layer set in mirror symmetry, which can be called the base plate, that is, the base plate is the bottom of the pipe fixing device 100. The assembly layer 10b located between the cover plate and the base plate is the second assembly layer, which can be called the interlayer plate. The cover plate, the interlayer plate and the base plate are combined into a finished pipe fixing device 100, and the number of interlayer plates can be adjusted according to the number of pipe arrangement layers, and the on-site assembly is flexible. The assembly layer 10 can be customized, and the number of fixing grooves 11 of each assembly layer 10 can be customized according to on-site requirements, and the number of assembly layers of each assembly layer 10 can be adjusted arbitrarily according to on-site conditions.

[0044] The dimensions of each assembled layer 10 can be customized according to different requirements. For example, the length of the entire assembled layer 10 can be a 4m module, and the specific length can be customized according to site needs. The cover plate can be provided with a fixing groove 11 only on the side facing the base plate, and the position of the fixing groove 11 can be set according to requirements. Similarly, the base plate can be provided with a fixing groove 11 only on the side facing the cover plate. The interlayer plate can be provided with fixing grooves 11 on both sides, and can be provided on both the side facing the cover plate and the side facing away from the cover plate.

[0045] To ensure the assembly accuracy and overall stability between adjacent assembly layers 10 , optionally, a positioning structure 20 is provided on the assembly layer 10 .

[0046] In one embodiment of the present application, the assembly layer 10 has a positioning structure 20 on the side with the fixing groove 11. The positioning structure 20 can achieve rapid positioning and fixing of the assembly layer 10 during assembly, avoiding misalignment of the assembly layer 10 and difficulty in pipe installation.

[0047] In order to reduce the difficulty of assembly and increase the speed of assembly, optionally, the positioning structure 20 includes a positioning groove 21 and a positioning connecting pin 22; the positioning groove 21 and the fixing groove 11 are both arranged on the same side of the assembly layer 10, and the opposite ends of the positioning connecting pin 22 are respectively connected to the relatively arranged positioning grooves 21 of the adjacent assembly layer 10.

[0048] In one embodiment of the present application, the positioning structure 20 includes a positioning slot 21 that can be used in conjunction with a positioning connecting pin 22. For example, multiple positioning slots 21 are pre-set on each assembly layer 10, such as positioning slots 21 at each of the four corners of the assembly layer 10, four positioning slots 21 on a single side, and eight positioning slots 21 on both sides. The positioning slots 21 can be sized to meet different needs, such as 20 mm in depth and 20 mm in diameter. When used in conjunction with the positioning connecting pin 22 for positioning, they can achieve rapid positioning and fixation between the assembly layers 10 during assembly.

[0049] The positioning connecting pins 22 do not need to be additionally provided and can be integrally formed with part of the assembled layer plate 10. The positioning connecting pins 22 can be directly set on the assembled layer plate 10, such as setting positioning grooves 21 and positioning connecting pins 22 on the diagonal lines of the four corners of the assembled layer plate 10, two positioning grooves 21 and two positioning connecting pins 22 are set on one side, and four positioning grooves 21 and four positioning connecting pins 22 are set on both sides.

[0050] In one embodiment of the present application, the positioning connecting pin 22 can be a cylindrical connecting pin made of PE material, with a height of 40 mm and a diameter of 18 mm, which can achieve rapid positioning and fixation when assembling the layer boards 10.

[0051] According to different requirements, the positioning structures 20 are arranged at the edge positions of both ends of the assembly layer 10; or the positioning structures 20 are arranged at intervals from the fixing grooves 11 to make the connection between adjacent assembly layer 10 more stable.

[0052] To facilitate the adaptability of the pipe fixture device 100 to various working conditions, in one embodiment of the present application, a break structure 30 is optionally provided on the assembly panel 10, located between the ends of the assembly panel 10. The location and number of break structures 30 can be adjusted according to different needs. For example, a single assembly panel 10 is 4 meters long, and a break structure 30 is reserved 2 meters in the middle of the assembly panel 10. The break structure 30 can be broken on-site to adjust the length of the assembly panel 10 to meet construction length requirements. Manual cutting of the length can also be performed on-site using a cutting machine.

[0053] In order to facilitate construction workers to quickly find the position of the express structure and also facilitate the construction workers to perform the breaking operation, in one embodiment of the present application, among the multiple assembly layers 10, the breaking structure 30 on the assembly layer 10 located at the edge is recessed in the surface of the assembly layer 10. Construction workers can intuitively see the recess on the assembly layer 10, or by touching the recess on the surface of the assembly layer 10, they can quickly find the position of the express structure. At the same time, the construction workers can operate along the recessed position to achieve the breaking operation of the assembly layer 10.

[0054] To reduce the number of manufacturing steps, the break structure 30 and the assembly layer 10 are optionally integrally formed. The assembly layer 10 can be manufactured by extrusion, and the break structure 30 is formed during the extrusion process, thereby reducing the number of manufacturing steps and reducing production costs.

[0055] Figure 6 This is a schematic diagram of the underground pipe system provided in a specific embodiment of the present application. Figure 6 As shown, the underground pipe system includes a pipe fixing device 100 and a medium pipe 200.

[0056] The buried pipe system includes: a plurality of pipe fixing devices 100 and medium pipes 200 as described above. The medium pipes 200 are arranged in the cavity 12 of the pipe fixing device 100, and adjacent medium pipes are connected through connectors.

[0057] The medium pipe 200 is installed on the pipe fixture 100. The medium pipes 200 on adjacent pipe fixtures 100 are connected via connectors 300. The medium pipe 200, including but not limited to PE materials, can be connected to the connectors 300 via electrofusion. After the connection is completed, the gaps between the pipe fixtures 100 are backfilled with fine sand to form a backfill layer 500. After all pipe fixtures 100 are connected and the gaps are backfilled, the outside is backfilled with original soil. Once the backfill reaches the predetermined elevation, civil construction can begin, greatly accelerating the construction schedule.

[0058] To facilitate communication with the external pipeline 400, the connector 300 optionally includes a three-way connecting pipe 301. The opposite ends of the three-way connecting pipe 301 are respectively connected to the adjacent medium pipes 200, and the third end of the three-way connecting pipe 301 is connected to the external pipeline 400. The three-way connecting pipe 301 can realize the connection between two adjacent medium pipes 200 and the external pipeline 400 such as a vertical buried pipe.

[0059] To further ensure the overall stability of the buried pipe system, the buried pipe system also includes external fixings 40, which secure adjacent pipe fixtures 100 together and integrate them into a single structure. External fixings 40 include, but are not limited to, cable ties. After multiple assembly panels 10 are assembled to form the pipe fixture 100, they are tied together with specialized cable ties to achieve an integrated structure. This facilitates on-site transport of the entire pipe fixture 100 and ensures the stability of the assembly between the assembly panels 10.

[0060] From the above description and practice, it can be seen that the pipe fixing device 100 and the buried pipe system provided by the present application have the following advantages compared with the existing technology: placing the pipe between the assembly layers can provide a fixing effect for the pipe, and during the construction process, the pipe will not be displaced, affecting the connection with other pipes; at the same time, relative to the shape of the pipe, it is easier to construct outside the assembly layer. Even in areas with poor geology, rapid molding with the assistance of the assembly layer can avoid mud backflow or pipe trench collapse problems, quickly form backfill, or pour outside the assembly layer. The use of a pipe fixing device helps to achieve quick connection on site, reduce the difficulty of protection, reduce construction time and save construction steps.

[0061] Those skilled in the art should understand that the above description is only a specific embodiment of the present application and is not intended to limit the present application. Any modifications, equivalent replacements, improvements, etc. made within the scope of the present application should be included in the scope of protection of the present application.
