Description

Technical Field

[0001] The invention relates to the technical field of tunnel insulation, and specifically discloses a novel honeycomb structure thermal insulation material and application thereof in cold region tunnels. Background Art

[0002] In recent years, with the rapid development of my country's economic construction, infrastructure such as roads, railways and tunnels have gradually extended to cold regions with extremely harsh climatic conditions, and the construction and number of railway tunnels in perennial or seasonal frozen soil areas have increased rapidly. Traditional cold-region tunnel insulation materials have problems such as heavy weight, poor insulation effect, and difficulty in processing and forming.

[0003] For example, the invention patent with patent application number 201410079350.1 discloses an antifreeze and heat-insulating tunnel in cold regions, including a tunnel primary lining, a tunnel waterproof board, a tunnel secondary lining and a fireproof board, wherein a gap is arranged between the tunnel secondary lining and the fireproof board, and an inflatable bag is also included, wherein the inflatable bag is arranged in the gap; a sealed inflatable bag is used to replace the traditional polyurethane insulation material, and the thermal conductivity of the sealed gas is about one-half of that of the polyurethane insulation material of the same thickness. The low thermal conductivity of the sealed gas is utilized to fill the sealed inflatable bag with gas, and the bag is arranged between the tunnel secondary lining and the fireproof board. When the existing cold region tunnel insulation is used to insulate the tunnel, the temperature inside the tunnel can be effectively protected from temperature loss because the inflatable bag is used to insulate the inside of the tunnel, but the structural strength of the insulation layer is weak and the plasticity is strong, which reduces the overall structural strength of the tunnel and easily leads to tunnel collapse. Summary of the invention

[0004] In view of this, the purpose of the present invention is to provide a new type of honeycomb structure thermal insulation material and its application in cold region tunnels, so as to solve the technical problem that when the existing cold region tunnel insulation is used for insulation, the structural strength of the insulation layer is weak and the plasticity is strong, which reduces the overall structural strength of the tunnel and easily leads to tunnel collapse.

[0005] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: a novel honeycomb structure thermal insulation material, comprising several groups of protective sleeves, wherein there is a matching sleeve between every two adjacent groups of the protective sleeves, one end of the matching sleeve is fixedly connected to the protective sleeve by bolts, and a connecting mechanism for fixing the protective sleeve and the matching sleeve is arranged between the other end of the matching sleeve and another group of the protective sleeves; several groups of honeycomb thermal insulation mechanisms for thermal insulation are arranged in the several groups of the protective sleeves, the honeycomb thermal insulation mechanisms include a first honeycomb panel and a second honeycomb panel, and the first honeycomb panel and the second honeycomb panel are both composed of several groups of honeycomb holes; the honeycomb holes are filled with phase change microcapsules, a thermal reaction layer and a hydrophilic porous layer in sequence, the outer surface of the hydrophilic porous layer is coated with a hygroscopic coating layer, a fixing frame is arranged in the honeycomb holes, and the phase change microcapsules are clamped in the fixing frame. The tunnel is insulated by the first honeycomb panel and the second honeycomb panel. The honeycomb structure material has the characteristics of light weight and high strength, and the honeycomb structure material has low thermal conductivity and good thermal insulation, which greatly reduces the convective heat exchange and heat conduction of the environment, and can maintain performance in a low temperature and high humidity environment. The honeycomb pores contain phase change microcapsules, thermal reaction layers and hydrophilic porous layers, which can further improve the thermal insulation effect of the thermal insulation layer.

[0006] Furthermore, the connection mechanism includes a connection sleeve, which is located between the matching sleeve and the protective sleeve; the matching sleeve is fixedly connected with a plurality of groups of first connection seats, the protective sleeve is fixedly connected with a plurality of groups of connection columns, and the plurality of groups of the first connection seats and the plurality of groups of the connection columns are respectively clamped on both sides of the connection sleeve; and a fixing component is arranged between the plurality of groups of connection columns and the plurality of groups of the first connection seats. Through the connection mechanism, two adjacent groups of protective sleeves are connected and fixed, so that the plurality of groups of fixed sleeves form a whole, ensuring the structural strength of the tunnel support, and at the same time enabling the honeycomb insulation mechanism to be spread throughout the tunnel, thereby protecting the tunnel.

[0007] Furthermore, the fixing assembly includes a fastening bolt, which is inserted into the first connecting seat, and one end of the connecting column is fixedly connected with a hexagonal block, and the hexagonal block is clamped on the fastening bolt; the first fixing slot and the connecting column are both provided with connecting slots, and the two groups of connecting slots are connected, and a connecting block is clamped in the connecting slot, and the connecting block is fixedly connected to the connecting sleeve by bolts; the connecting block and one end of the connecting slot cross section are both trapezoidal. The two adjacent groups of protective sleeves are fixed by the fastening assembly, and when the fastening assembly connects the two groups of protective sleeves, the position of the protective sleeves can be adjusted at the same time, so that the two groups of protective sleeves are more tightly connected. At the same time, since one group of protective sleeves is only a shell when connected, it is more convenient to move the protective sleeves.

[0008] Furthermore, the honeycomb heat preservation mechanism includes two groups of first honeycomb panels and two groups of second honeycomb panels, the two groups of the first honeycomb panels and the two groups of the second honeycomb panels form an arch; the bottom ends of the two groups of the first honeycomb panels are provided with a third connecting plate, and a plurality of groups of fourth clamping blocks are fixedly connected below the first honeycomb panels, and the plurality of groups of the fourth clamping blocks are clamped on the third connecting plate. The two groups of the first honeycomb panels and the two groups of the second honeycomb panels can fit the protective shell, thereby playing a role in heat preservation of the tunnel, and the protective shell is only used to protect the honeycomb panels to prevent the honeycomb panels from being eroded by soil, thereby reducing the service life of the honeycomb panels.

The first protective frame and the second protective frame are used to protect the first honeycomb panel and the second honeycomb panel. Since the first honeycomb panel and the second honeycomb panel are arched, the forces received by the first honeycomb panel and the second honeycomb panel when subjected to force are not perpendicular to the first honeycomb panel and the second honeycomb panel. The first honeycomb panel and the second honeycomb panel have unique structures, and the strength of the side force is much lower than the strength of the front force. In order to ensure that the first honeycomb panel and the second honeycomb panel can exert their complete structural strength, the first honeycomb panel and the second honeycomb panel are protected by the first protective frame and the second protective frame, and the inclined force is converted into a force perpendicular to the first honeycomb panel and the second honeycomb panel.

[0010] Furthermore, a locking mechanism is provided between each two adjacent groups of the honeycomb heat preservation mechanisms, and the locking mechanism includes two groups of first connecting plates and two groups of second connecting plates, the two groups of the first connecting plates and the two groups of the second connecting plates form an arch, the second connecting plates are provided with second clamping blocks, and the second clamping blocks are clamped in the first connecting plates; the first connecting plate is located between two adjacent groups of the first honeycomb plates, and the first honeycomb plates are provided with a plurality of groups of first clamping blocks, and the plurality of groups of the first clamping blocks are clamped on the first connecting plate; the second connecting plate is located between two adjacent groups of the first protective frames, and the first protective frames are provided with a plurality of groups of first clamping blocks, and the plurality of groups of the first clamping blocks are clamped on the second connecting plate. The locking mechanism is used to fix two adjacent groups of honeycomb heat preservation mechanisms, so that the plurality of groups of honeycomb heat preservation mechanisms form a whole, can insulate the tunnel, and enhance the structural strength of the honeycomb heat preservation mechanism.

[0011] Furthermore, every two adjacent groups of the first protection frames are in contact with the corresponding first connecting plates, and every two adjacent groups of the second protection frames are in contact with the corresponding second connecting plates; the first protection frame and the second protection frame are fixedly connected to the first connecting plate and the second connecting plate by bolts; the third connecting plate is in contact with the corresponding first protection frame, the first protection frame is fixedly connected to the third connecting plate by bolts, the third connecting plate is provided with a third clamping block, and the third clamping block is clamped in the corresponding first connecting plate. The first protection frame and the second protection frame are fixedly connected to the locking mechanism, so as to cooperate with the locking mechanism to surround the honeycomb insulation mechanism, thereby protecting the honeycomb insulation mechanism and ensuring that the honeycomb insulation mechanism can be stressed in an ideal state.

[0012] Application of a novel honeycomb structure thermal insulation material in cold region tunnels, characterized in that it comprises the following steps: S1: The staff first moves the protective cover, the first honeycomb panel, the second honeycomb panel, the first protective frame, the first connecting plate, the second connecting plate and the second protective frame into the tunnel, and then installs the two groups of first honeycomb panels on the two groups of third connecting plates, and then installs the two groups of first connecting plates on the two groups of third connecting plates, fixes the first honeycomb panels, and then installs the two groups of second connecting plates on the two groups of first connecting plates, and then fixes the two groups of second connecting plates with bolts, and then installs the two groups of second honeycomb panels on the two groups of second connecting plates; S2: The staff installs the two groups of first connecting plates on the other ends of the two groups of third connecting plates, and then installs the two groups of second connecting plates on the two groups of first connecting plates, and fixes the two groups of second connecting plates with bolts. At this time, the two groups of first honeycomb panels and the two groups of second honeycomb panels are fixedly connected, and the staff fixes the first protection frame and the second protection frame on the two groups of first connecting plates and the two groups of second connecting plates with bolts, and protects the first honeycomb panels and the second honeycomb panels with the first protection frame and the second protection frame. The staff reciprocates until the protective cover is filled with the first honeycomb panels and the second honeycomb panels, and then the staff installs the matching cover on the protective cover with bolts; S3: Then the staff installs the connecting sleeve on the installed matching sleeve, and the staff inserts the fastening bolts into the first connecting seat and the first fixing groove, and fixes the protective sleeve and the matching sleeve by the fastening bolts; S4: The staff then installs another set of protective covers in the first connecting seat, inserts the connecting column into the first fixing groove, and then inserts the connecting block into the connecting groove. The staff moves the protective covers to the designated position through the connecting block, and fixes the connecting block and the connecting cover with bolts, and repeats this process until the installation of the entire tunnel is completed.

[0013] The working principle and beneficial effects of this solution are: When in use, it can be installed between the primary support and the secondary lining, or on the surface of the secondary lining, to form a honeycomb material insulation layer; in high-altitude and cold areas, one layer can be installed between the primary support and the secondary lining, and another layer can be installed on the surface of the secondary lining to form a double-layer insulation structure.

In terms of production methods, honeycomb structural materials can be produced and installed in a modular manner, which is more suitable for on-site construction and maintenance in tunnels. Unique connection mechanisms can also be designed to ensure the stability and durability of the honeycomb structure in tunnel applications. BRIEF DESCRIPTION OF THE DRAWINGS

[0022] The application of a new type of honeycomb structure thermal insulation material in a cold region tunnel includes the following steps: S1: The staff first transports the protective cover 101, the locking mechanism and several groups of honeycomb insulation mechanisms into the tunnel, and then the staff places two groups of third connecting plates 211 at the designated position, and then respectively clamps several groups of fourth card blocks 213 on the two groups of first honeycomb plates 201 into the corresponding fourth card slots 214. At this time, the first honeycomb plates 201 and the third connecting plates 211 are initially fixed, and then the staff respectively installs the two groups of first connecting plates 206 on the two groups of third connecting plates 211, so that one group of third card blocks 212 The first honeycomb panel 201 is mounted on the first connecting plate 206, and the first card blocks 205 on the first honeycomb panel 201 are respectively mounted in the first card slots 207.

The staff then moves the two groups of second connecting plates 208 so that one end of the two groups of second connecting plates 208 is in contact, and then fixes the two groups of second connecting plates 208 with bolts.

[0023] S2: Then the staff installs the two groups of second honeycomb panels 202 on the second connecting plate 208 respectively, so that the several groups of first card blocks 205 on the second honeycomb panels 202 are clamped in the second connecting plate 208. At this time, one end of the second honeycomb panel 202 contacts with the other group of second honeycomb panels 202, and the other end of the second honeycomb panel 202 contacts with the corresponding first honeycomb panel 201. Then the staff installs the two groups of first connecting plates 206 on the other end of the third connecting plate 211, and then installs the two groups of second connecting plates 208 on the two groups of first connecting plates 206, and fixes the two groups of second connecting plates 208 with bolts. At this time, the two groups of locking mechanisms are respectively located on both sides of the honeycomb insulation mechanism, and the locking mechanism fixes the two groups of first honeycomb panels 201 and the two groups of second honeycomb panels 202.

[0024] S3: The staff moves the first protective frame 203 to contact with the first honeycomb panel 201, and then fixes the first protective frame 203 to the first connecting plate 206 and the third connecting plate 211 by bolts, and then the staff moves the second protective frame 204 to contact with the second honeycomb panel 202, and fixes the second protective frame 204 between the two groups of second connecting plates 208 by bolts, and at the same time, the first protective frame 203 and the second protective frame 204 are fixedly connected by bolts, and then the staff moves the fixed honeycomb insulation mechanism into the protective cover 101, and then the staff continues to install the honeycomb insulation mechanism and the locking mechanism until the protective cover 101 is full of the honeycomb insulation mechanism, and then the staff moves the matching sleeve 102 to align the matching sleeve 102 with the protective cover 101, and then moves the matching sleeve 102 to contact with the protective cover 101, at this time, the matching sleeve 102 is sleeved on one end of one group of honeycomb insulation mechanisms, and then the staff fixes the protective cover 101 and the matching sleeve 102 by bolts.

[0025] S4: When it is necessary to continue laying the protective cover 101, the staff first moves the connecting mechanism and another set of protective covers 101 into the tunnel, and then the staff installs the connecting cover 104 on the mating cover 102 that has been installed. At this time, the first connecting seat 103 is located in the second fixing groove 306, and then the staff inserts the fastening bolt 301 into the first connecting seat 103 and the first fixing groove 303. At this time, the protective cover 101 and the mating cover 102 are fixedly connected by the fastening bolt 301.

[0026] S5: Then the staff installs another set of protective covers 101 in the first connecting seat 103, and inserts the connecting column 304 into the first fixing groove 303. At this time, the hexagonal block 305 is clamped in the hexagonal groove 302. Then the staff inserts the connecting block 307 into the connecting groove 308, and moves the protective cover 101 to the specified position through the connecting block 307, so that the protective cover 101 fits with the connecting sleeve 104. The staff fixes the connecting block 307 and the connecting sleeve 104 with bolts. At this time, the protective cover 101 and the connecting sleeve 104 are fixedly connected. The staff continues to install the honeycomb insulation mechanism, and repeats this process until the installation of the entire tunnel is completed.

[0027] When implementing: When installing the connecting block 307, the staff first moves the connecting block 307 into the connecting groove 308, and the inclined surface of the connecting block 307 contacts the inclined surface of the connecting groove 308. Then the staff moves the connecting block 307 into the connecting groove 308. At this time, since the protective sleeve 101 is not completely in contact with the connecting sleeve 104, the connecting block 307 cannot be completely mounted in the connecting groove 308. At this time, the staff uses a hydraulic cylinder or other device to push the connecting block 307 to slide in the connecting groove 308. Since the cross-sections of the connecting block 307 and the connecting groove 308 are inclined, when the connecting block 307 slides in the connecting groove 308, the connecting block 307 can drive the protective sleeve 101 to move toward the connecting sleeve 104. When the protective sleeve 101 contacts the connecting sleeve 104, the connecting block 307 is completely located in the connecting groove 308. At this time, the staff fixes the connecting block 307 and the connecting sleeve 104 with bolts, thereby fixing the protective sleeve 101 and the connecting sleeve 104.

[0028] Honeycomb structure thermal insulation materials can be installed between the primary support and the secondary lining, or they can be installed on the surface of the secondary lining to form a honeycomb material insulation layer. In high-altitude and cold areas, a layer can be installed between the primary support and the secondary lining, and another layer can be installed on the surface of the secondary lining to form a double-layer insulation structure. This method uses honeycomb structure materials because they are lightweight and high-strength, and the honeycomb structure materials have low thermal conductivity and good thermal insulation properties, which greatly reduces environmental convective heat transfer and heat conduction, and can maintain performance in low temperature and high humidity environments to prevent performance degradation caused by environmental changes. Secondly, honeycomb materials can be designed with honeycomb structures of specific geometric shapes to maximize thermal insulation effects and structural strength. In terms of production methods, honeycomb structure materials can be produced and installed in a modular manner, which is more suitable for on-site construction and maintenance in tunnels. Unique connection mechanisms can also be designed to ensure the stability and durability of the honeycomb structure in tunnel applications.

[0029] Phase change microcapsules 402 can change phases (solid, liquid, gas) at a specific temperature and can provide latent heat. The process of changing the phase of a substance is called a phase change process. At this time, the phase change material absorbs or releases a large amount of latent heat, thereby generating a cold storage or heat storage function. When the temperature in the honeycomb hole 401 is too low, cold storage is performed, and when the temperature in the honeycomb hole 401 is too high, heat storage is performed, thereby playing a role in heat preservation.

[0030] The main purpose of the thermal insulation layer in cold-region tunnels is to maintain the original thermal condition of the surrounding rock and prevent damage due to frost heave and thaw settlement. By laying thermal insulation materials, the freezing of the tunnel lining and surrounding rock in cold seasons and the melting in warm seasons can be reduced, thereby reducing the freeze-thaw cycle and keeping the tunnel warm.

[0031] The hydrophilic porous layer 404 has excellent hygroscopicity and moisture retention, thanks to its porous structure and the choice of hydrophilic materials. When the porous layer absorbs water, water molecules fill the pores to form a continuous water film. This water film plays a key role in thermal insulation because it can effectively hinder the transfer of heat. Specifically, water has a high thermal conductivity, but in a porous structure, due to the tortuosity of the pores and the continuity of the water film, the heat transfer path is greatly extended, thereby slowing down the heat transfer rate and thus insulating the tunnel.

[0032] When the humidity is high, the hygroscopic coating layer 405 can absorb excess moisture and release moisture when the humidity is low, thereby keeping the coating and the substrate dry, thereby cooperating with the phase change microcapsules 402, the thermal reaction layer 403 and the hydrophilic porous layer 404 to ensure the heat insulation effect, thereby ensuring that a constant temperature can be maintained in the tunnel.

[0033] The above is only an embodiment of the present invention, and the common knowledge such as the known specific structure and characteristics in the scheme is not described in detail here. It should be pointed out that for those skilled in the art, several modifications and improvements can be made without departing from the structure of the present invention, which should also be regarded as the protection scope of the present invention, and these will not affect the effect of the implementation of the present invention and the practicality of the present invention.
