Description

Technical Field

[0001] This utility model belongs to the field of drainage blind pipe technology, and in particular relates to a heat-insulating drainage blind pipe based on a vacuum insulation board. Background Technology

[0002] In the fields of civil engineering, underground structures and slope protection, drainage blind pipes are a key underground drainage facility widely used in tunnel lining, behind retaining walls, roadbeds and foundations to collect and channel groundwater, reduce pore water pressure, prevent leakage and erosion, and ensure the stability and durability of engineering structures.

[0003] Document CN222251815U discloses a drainage blind pipe structure, including a drainage blind pipe assembly. The outer wall of the assembly is covered with geotextile, a connecting component is installed on one side, and a second partition plate is installed on the inner wall. The assembly includes a pipe with a connecting block at its front end and an annular insert on one side. A first sealing ring is glued to one side of the annular insert. This improved drainage blind pipe structure enhances the sealing performance of the connection gap between two sets of drainage blind pipes, preventing sludge-containing water from directly entering the drainage pipe through the connection gap and causing blockage. Simultaneously, the second partition plate divides the pipe interior into four spaces, reducing water seepage from the bottom of the pipe, thus reducing drainage efficiency. However, in practical use, conventional drainage blind pipes lack necessary insulation structures and are unsuitable for low-temperature environments. Therefore, further improvements are needed. Utility Model Content

[0004] The purpose of this invention is to address the problem that conventional blind drain pipes in the prior art lack the necessary insulation structure and are difficult to apply to low-temperature environments, and to propose an insulated blind drain pipe based on a vacuum insulation board.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A heat-insulating drainage blind pipe based on a vacuum insulation panel includes a blind pipe body, an inner layer connected inside the blind pipe body, a heat insulation layer connected to the outer surface of the blind pipe, and a protective layer provided outside the heat insulation layer.

[0006] As a further description of the above technical solution: The outer periphery of the insulation layer is connected to a plurality of reinforcing rings arranged in a linear array, and the reinforcing rings are disposed between the protective layer and the insulation layer.

[0007] As a further description of the above technical solution: The insulation layer is made of vacuum insulation material to reduce heat loss.

[0008] As a further description of the above technical solution: The protective layer is a cushioning material or a reinforcing protective layer, used to enhance the overall strength.

[0009] As a further description of the above technical solution: The inner layer is coated with a waterproof membrane.

[0010] As a further description of the above technical solution: The main body of the blind tube is a porous tube made of polymer material.

[0011] In summary, due to the adoption of the above technical solution, the beneficial effects of this utility model are: 1. By setting an insulation layer made of vacuum insulation material on the outer surface of the blind pipe body, the rate of heat loss from the internal fluid to the external cold environment is greatly reduced. This effectively prevents problems such as pipe blockage or cracking caused by internal water freezing in winter, ensuring the smooth and long-term stable operation of the drainage system. It is especially suitable for harsh environments such as high altitude and frozen soil.

[0012] 2. The protective layer set outside the insulation layer provides solid physical protection for the relatively fragile vacuum insulation board, which can resist external impacts and pressures such as backfill soil and construction equipment, prevent the insulation layer from breaking and failing, and extend the service life of the blind pipe.

[0013] 3. By adding a linear array of reinforcing rings between the protective layer and the insulation layer, the ring stiffness and longitudinal bending resistance of the blind pipe are further enhanced, making it less prone to deformation or flattening when subjected to large soil loads, thus ensuring the stability of the drainage space.

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0017] Please see Figures 1-2 This utility model provides a technical solution: a heat-insulating drainage blind pipe based on a vacuum insulation board, comprising a blind pipe body 3, an inner layer 4 connected inside the blind pipe body 3, a heat insulation layer 5 connected to the outer surface of the blind pipe, a protective layer 1 provided outside the heat insulation layer 5, and multiple reinforcing rings 2 arranged in a linear array connected to the outer periphery of the heat insulation layer 5, the reinforcing rings 2 being disposed between the protective layer 1 and the heat insulation layer 5, the heat insulation layer 5 being a vacuum insulation material used to reduce temperature loss, the protective layer 1 being a buffer material or a reinforced protective layer 1 used to enhance overall strength, the inner layer 4 being coated with a waterproof membrane, and the blind pipe body 3 being a porous pipe made of polymer material.

[0018] The specific parameters of this blind drain pipe are as follows: Working principle: When this insulated drainage blind pipe is laid in the roadbed of a cold region, groundwater flows through the main body 3 and inner layer 4 of the blind pipe. In winter, the external ambient temperature can drop to below -30℃. Due to the extremely low thermal conductivity of the insulation layer 5, it forms an efficient thermal barrier, which greatly hinders the transfer of cold energy from the roadbed soil to the pipe and the loss of heat from the water inside the pipe to the outside. This allows the temperature of the water flowing inside the pipe to always be maintained above the freezing point, thereby effectively preventing blockage of the drainage pipe due to freezing and ensuring the smooth flow of the drainage system. At the same time, because the main body 3 of the blind pipe has high compressive and puncture resistance, combined with the outer protective layer 1, it can withstand the pressure of the backfill soil and the extrusion of gravel from the roadbed, ensuring the integrity of the drainage blind pipe and maintaining its superior insulation performance for a long time.

[0019] 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.
