DETAILED DESCRIPTION

[0040] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. The following embodiments are used to illustrate the present invention but are not used to limit the scope of the present invention.

[0041] In the description of the present invention, it should be noted that the terms "upper", "lower", "front", "back", "left", "right", "vertical", "inside", "outside", etc., indicating directions or positional relationships, are based on the directions or positional relationships shown in the accompanying drawings. They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction. Therefore, they cannot be understood as limitations on the present invention.

[0042] In the description of this utility model, it should be noted that, unless otherwise specified or limited, the terms "mounted," "connected," and "connected" should be understood in a broad sense. For example, they can refer to fixed connections, detachable connections, or integral connections; mechanical connections, electrical connections; and direct connections or indirect connections through an intermediary. Those skilled in the art will understand the specific meanings of these terms in this utility model based on the specific circumstances.

[0043] like Figures 1 to 3 As shown, the utility model provides a laying structure for glue liquid transmission, which includes a pipe trench 1, a first isolation layer 2, a second isolation layer 3, and a cover plate 4.

[0044] The pipe trench 1 is a long strip-shaped groove 5 , and an opening is provided at the top of the pipe trench 1 . The opening is also in the shape of a long strip and extends along the length direction of the pipe trench 1 .

[0045] The design of the long strip groove 5 effectively increases the bending, compression and tensile resistance of the material pipeline 6. This design makes the material pipeline 6 more stable when subjected to external forces, reduces the possibility of deformation of the material pipeline 6, and thus ensures smooth transmission of the fluid.

[0046] The pipe trench 1 can be constructed by prefabrication in a factory or by pouring concrete on site.

[0047] Precast concrete components are produced in factories, which allows strict control of various parameters during the production process to ensure the quality of the components.

[0048] Precast concrete components are assembled on site, which reduces the time for on-site pouring and curing and shortens the construction period.

[0049] Precast concrete components reduce the time and workload of construction at the construction site, and reduce pollution and impact on the construction site.

[0050] Precast concrete components reduce the time and workload of construction at the construction site, and reduce pollution and impact on the construction site.

[0051] During the construction process of cast-in-place concrete, the concrete is poured to form an integral structure, which can ensure the strength of the entire structure and is suitable for structural requirements of various complex shapes and sizes. Because the concrete is poured at the construction site, it can be trimmed and adjusted according to actual conditions.

[0052] Cast-in-place concrete has high compressive, tensile and shear strength, which can meet the structural strength requirements of buildings.

[0053] Cast-in-place concrete has the characteristics of water resistance, wind resistance, corrosion resistance, etc., which can ensure the service life of the building.

[0054] The top of the trench 1 refers to the portion of the trench 1 close to the floor. Setting the opening at the top of the trench 1 facilitates the placement of the material pipeline 6 and improves the laying efficiency of the material pipeline 6.

[0055] The size of the trench 1 is determined according to actual needs. Generally, the width and depth must be sufficient to accommodate the material pipeline 6 and the surrounding insulation and heat preservation materials, as well as maintenance space.

[0056] described Figure 1 The trench 1 is long and narrow, but in other embodiments, the shape of the trench 1 can be adjusted according to actual needs, and the direction of the material pipeline 6 can also be adjusted according to the actual slope; at the same time, the extension direction of the opening can also be adjusted with the shape of the trench 1.

[0057] The laying slope of the material pipeline 6 is based on the characteristics of the material. The viscosity is high and it is not easy to flow. Therefore, a certain slope is adopted to assist. Through mechanical calculation, the optimal angle is calculated according to parameters such as length, viscosity, pipe diameter, pressure, gravity, etc., thereby determining the slope.

[0058] Specifically, the appropriate inclination angle for conveying materials using a circular tube is determined by the characteristics of the material, the material and shape of the tube, and the conditions of use, and is closely related to whether it is dynamic or static.

[0059] When the material slides on the smooth plate, the inclination angle of the plate is required to be a ≥ P (P: friction angle of the granular material on the plate; e: reference coefficient value under different tube shapes and different material filling coefficients, greater than 1).

[0060] When the material flows in the pipe, the inclination angle of the pipe is required to be a≥ep. For example: when the material filling coefficient is 0.3, for a circular pipe: a≥p+(3°~5°); when the material filling coefficient is 0.5, for a circular chute: a≥p+(5°~7°).

[0061] The friction coefficient of the material against the pipe wall is different when it is sliding and stationary. Generally speaking, the dynamic friction coefficient is about 0.7 times the static friction coefficient. If the initial velocity of the material is very low or close to zero, the pipe inclination angle needs to be increased by 3° to 5° or more based on the above calculation.

[0062] The first isolation layer 2 and the second isolation layer 3 are provided between the groove 5 and the material pipeline 6 for heat insulation of the material pipeline 6 .

[0063] The first insulating layer 2 and the second insulating layer 3 together form a double-layer thermal insulation structure. This design can effectively reduce the heat exchange between the material pipeline 6 and the external environment, thereby improving the thermal insulation effect.

[0064] The groove 5 itself can also serve as a part of the heat preservation structure. By designing its shape and size, it can further reduce heat loss and improve the overall heat preservation performance.

[0065] The first isolation layer 2 and the second isolation layer 3 are filled or wrapped with two different materials. The first isolation layer 2 and the second isolation layer 3 can not only play a role in heat preservation, but also provide additional support for the material pipeline 6 to enhance its structural stability.

[0066] The cover plate 4 is disposed at the opening of the groove 5 to close the opening.

[0067] The provision of the cover plate 4 not only closes the opening of the groove 5 to prevent interference from the external environment, but also provides additional protection for the entire thermal insulation structure and enhances its structural stability.

[0068] In an optional embodiment of the present invention, the first insulating layer 2 is arranged outside the material pipeline 6 to keep the material pipeline 6 warm, which can effectively reduce the heat loss to the external environment through the material pipeline 6, thereby improving the insulation effect.

[0069] The first isolation layer 2 is arranged on the outer wall of the material pipeline 6 for heat preservation of the material pipeline 6 , and needs to have a certain thickness, which can be set to 200 mm according to actual needs, or other thicknesses.

[0070] The second isolation layer 3 is provided between the first isolation layer 2 and the groove 5 , and is used to seal the groove 5 and prevent gas from being deposited inside the groove 5 .

[0071] The provision of the second insulating layer 3 not only provides a sealing effect for the groove 5 , but also further reduces the heat exchange between the groove 5 and the external environment, thereby forming a more effective heat preservation system together with the first insulating layer 2 .

[0072] The order of the first isolation layer 2 and the second isolation layer 3 can be adjusted according to actual needs and is not limited to the specific order mentioned in this embodiment.

[0073] Before the heat insulation treatment is performed, the pipe trench 1 must be subjected to anti-corrosion treatment to prevent acid rain or materials from entering and affecting the material pipeline 6 .

[0074] In an optional embodiment of the present invention, the first isolation layer 2 is used to wrap the outside of the material pipe 6;

[0075] The first insulating layer 2 can effectively reduce the temperature loss inside the material pipeline 6, especially under extreme weather conditions (such as cold winter or hot summer), which helps to maintain the temperature of the medium inside the material pipeline 6 stable and improve energy utilization efficiency.

[0076] By reducing temperature fluctuations, the first insulating layer 2 can also reduce the stress and deformation of the material pipeline 6 caused by thermal expansion and contraction, thereby protecting the structural integrity of the material pipeline 6.

[0077] The second isolation layer 3 is filled between the first isolation layer 2 and the accommodation cavity formed by the groove 5 .

[0078] By filling the second isolation layer 3 , the voids in the accommodating cavity can be effectively reduced, and the overall sealing performance can be improved, which helps to prevent medium leakage and ensure the safe operation of the material pipeline 6 .

[0079] The second isolation layer 3 can also serve to isolate the external environment. It can prevent harmful substances such as water, moisture, and corrosive substances from penetrating into the vicinity of the material pipeline 6, thereby protecting the integrity and performance of the material pipeline 6.

[0080] In an optional embodiment of the present invention, the second isolation layer 3 is respectively connected to the outer periphery of the first isolation layer 2, the inner wall of the groove 5 and the inner wall of the cover plate 4, ensuring comprehensive sealing of the entire structure and effectively preventing interference from the internal medium of the material pipeline 6 or the external environment.

[0081] The connection between the second isolation layer 3 and multiple components enhances the connection strength of the entire structure, making the entire system more stable and reliable.

[0082] The second isolation layer 3 completely fills the outer periphery of the first isolation layer 2 and the inner wall of the groove 5 without any gap in between, which can better prevent gas deposition.

[0083] In an optional embodiment of the present invention, the thickness of the first isolation layer 2 is greater than the thickness of the second isolation layer 3 .

[0084] In order to meet the insulation requirement of -30 degrees Celsius, the thickness of the first insulating layer 2 is 200 mm, and the remaining space of the groove 5 is filled with a foaming agent, which can also be adjusted according to other conditions.

[0085] The thickness of the first isolation layer 2 and the thickness of the second isolation layer 3 can be adjusted according to actual needs and are not limited to the thickness in this embodiment.

[0086] The pipe trench 1 includes a bottom wall 11 and left and right side walls 12 that are integrally formed.

[0087] There is a distance between the material pipeline 6 and the inside of the bottom wall 11, which is used to set the pipeline support 7. At the same time, the first isolation layer 2 and the second isolation layer 3 are respectively set to ensure the thermal insulation protection effect.

[0088] A gap is set between the side of the material pipe 6 and the inside of the side wall 12, which is determined to be 300 mm based on actual experience.

[0089] The side wall 12 should have a certain depth to prevent the frozen soil layer from affecting the trench 1.

[0090] The space where the material pipeline 6 is located must be reasonably designed. If the space margin is too large, more heat will be lost, and it will be more difficult to take insulation measures, and the cost will also increase.

[0091] The distance between the upper portion of the material pipe 6 and the opening of the groove 5 can be set to 300 mm, and can also be set according to actual conditions.

[0092] The bottom wall 11 and the side wall 12 both have a thickness. To ensure that the trench 1 can withstand a larger load, the left and right side walls 12 are both set to a certain thickness, which may be 200 mm. The bottom wall 11 may be 200 mm thick, or different thicknesses may be set according to specific actual conditions.

[0093] Transverse steel bars 13 and longitudinal steel bars 14 are provided inside the bottom wall 11 and the side walls 12 to enhance the strength of the structure.

[0094] The transverse reinforcement 13 and the longitudinal reinforcement 14 can both be selected to have a diameter of 10 mm and be arranged at intervals of 150 mm. Different intervals can also be set according to specific actual conditions and different reinforcement diameters can be selected.

[0095] The pipe trench 1 is arranged on the upper part of the foundation structure 8 and is used to evenly transfer the load of the pipe trench 1 to the foundation to ensure the stability and safety of the entire structure.

[0096] There is a distance between the basic structure 8 and the outside of the bottom wall 11. The two sides of the basic structure 8 extend out of the outside of the bottom wall 11 by 100 mm, which can also be adjusted according to actual needs.

[0097] The base structure 8 can diffuse the load of the bottom wall 11 and reduce deformation of the foundation. Through its good bearing performance, the base structure 8 can evenly distribute the weight of the superstructure to the foundation, thereby reducing the risk of foundation settlement.

[0098] The foundation structure 8 can be made of C20 concrete with a thickness of 100 mm. The foundation structure 8 serves as an isolation layer to prevent direct contact between the soil and the superstructure, reducing the erosion of the building by moisture, chemicals, etc.; at the same time, it can also prevent harmful substances in the soil from eroding the foundation reinforced concrete, thereby extending the service life of the building.

[0099] When the water stability of the soil foundation is poor, the foundation structure 8 can effectively improve the water stability and frost heave resistance of the soil foundation.

[0100] In an optional embodiment of the present invention, the first isolation layer 2 is made of at least one of aluminum silicate rock wool or glass wool, and various thermal insulation materials such as slag wool, expanded perlite, ceramic fiber, aerogel, vacuum insulation board, calcium silicate board, etc. can also be selected.

[0101] The second isolation layer 3 is made of a foaming agent.

[0102] Aluminum silicate rock wool is an environmentally friendly thermal insulation material made from rock (such as basalt, dolomite, etc.) as the main raw material. It is melted at high temperature and a certain amount of binder is added. It is made into fibers on a high-speed centrifuge and then processed through double-sided pressurization, three-sided drying, and one-side surface tape.

[0103] Aluminum silicate rock wool has low thermal conductivity and can effectively prevent heat transfer; aluminum silicate rock wool is a non-flammable material that can effectively improve fire resistance; aluminum silicate rock wool has excellent chemical stability and is not easily corroded by acids, alkalis and other chemical substances; aluminum silicate rock wool does not cause pollution to the environment during production and use, and is an environmentally friendly thermal insulation material.

[0104] When using aluminum silicate rock wool, it should be ensured that it complies with relevant standards and specifications to ensure its quality and safety; during the installation process, care should be taken to maintain the integrity and continuity of the aluminum silicate rock wool to avoid damage or gaps; during use, the status of the aluminum silicate rock wool should be checked regularly and damaged or aging materials should be replaced in a timely manner.

[0105] Glass wool is a general term for fibrous silicate minerals that can be split into slender and flexible fibers and can be used. It is mainly made of glass as the main raw material. After high-temperature melting, it is made by centrifugal or blowing methods.

[0106] Because there are a large number of tiny pores inside the glass wool, the thermal conductivity of the still air in these pores is very low, so the glass wool has good thermal insulation properties.

[0107] Glass wool has good chemical stability and is not easily corroded by chemicals such as acids and alkalis. It can maintain its stable performance in a humid environment and will not become moldy or rot.

[0108] A foaming agent is a substance that can make the object form pores. It is divided into chemical foaming agents, physical foaming agents and surfactants. The main function of a foaming agent is to produce a large amount of foam. These foams have excellent properties and can meet the foaming technical requirements of various products.

[0109] The second isolation layer 3 may also be made of chemical foaming materials, azo compounds, sulfonylhydrazide compounds, nitroso compounds, carbonates (calcium carbonate, magnesium carbonate, sodium bicarbonate, etc.), water glass, silicon carbide, carbon black, etc.

[0110] Physical foaming materials, low-boiling-point alkanes, fluorocarbon compounds, compound physical foaming agents, etc. can also be selected. The materials are not limited to the materials listed above, and other types of materials can also be selected according to actual needs.

[0111] In an optional embodiment of the present utility model, the laying structure further includes a pipe support 7;

[0112] In order to improve the thermal insulation effect of the material pipeline 6, the pipeline support 7 is provided in the laying structure, such as Figure 2 shown.

[0113] The pipe support 7 includes a fixing portion and a supporting portion connected to each other;

[0114] The fixing portion of the pipe support 7 is located in the second isolation layer 3 and is fixed to the inner wall of the groove 5 .

[0115] The material pipeline 6 is effectively prevented from being displaced and shaken during operation. The pipeline support can be welded with a steel structure and can be fixed with bolts.

[0116] The supporting portion of the pipe support 7 passes through the first insulating layer 2 to support the material pipe 6. The second insulating layer 3 has a distance from the inner wall of the pipe trench 1, which reduces heat loss through the inner wall of the pipe trench 1, thereby improving the thermal insulation effect.

[0117] In an optional embodiment of the present invention, the pipe supports 7 are arranged at intervals along the length direction of the groove 5 .

[0118] To ensure the support effect and facilitate subsequent inspection and maintenance, such as Figure 3 As shown, the pipe supports 7 are arranged at intervals of 2 meters, and different intervals can also be set according to actual conditions.

[0119] The contact portion between the pipe support 7 and the material pipe 6 is an arc-shaped structure.

[0120] The curved structure can more effectively disperse and bear the weight and load from the pipeline. Compared with the straight structure, the curved structure has more advantages in mechanics and can better resist the force of external loads, thereby improving the load-bearing capacity of the entire support system.

[0121] The arc-shaped structure provides better support and fixing effects at the contact portion between the pipe support 7 and the material pipe 6. This structure can reduce deformation and displacement of the support caused by uneven force, thereby enhancing the stability of the entire support system.

[0122] The arc-shaped structure design makes the contact between the pipe support 7 and the material pipe 6 smoother and more uniform. This design can reduce the friction and wear between the support and the pipe, and extend the service life of the pipe support 7 and the material pipe 6; at the same time, the arc-shaped structure can also reduce the stress concentration phenomenon generated when the pipe is subjected to force, and further protect the pipe from damage.

[0123] The arc-shaped structure design makes the installation and disassembly of the pipe support 7 more convenient and quick. This structure can reduce the complexity and difficulty of the construction process and improve construction efficiency.

[0124] In an optional embodiment of the present invention, the cross-sections of the left and right sides of the cover plate 4 gradually increase from the upper portion to the contact portion of the pipe trench 1;

[0125] That is, the cross section from the upper part to the contact part of the pipe trench 1 gradually increases. This design not only enhances the load-bearing capacity of the cover plate 4, but also can prevent the intrusion of external factors such as rainwater to a limited extent.

[0126] The lower portion of the cover plate 4 is aligned with the outer portions of the left and right sides of the pipe trench 1, which can achieve a better covering effect.

[0127] In an optional embodiment of the present invention, the upper portion of the cover plate 4 is filled with an asphalt layer 15, and the asphalt layer 15 is consistent with the outdoor floor elevation;

[0128] The cover plate 4 is provided with a hook 16 , and the hook 16 protrudes from the asphalt layer 15 .

[0129] The pipe ditch 1 is outdoors and water will leak from the cover plate 4 on rainy days, so a water accumulation pit is set in the low-lying part of the pipe ditch 1.

[0130] In addition, waterproof felt paper is arranged on the cover plate 4 and covered with a layer of asphalt and soil to prevent the felt paper from falling off.

[0131] The cover plate 4 is provided with a hook 16 , and the hook 16 protrudes from the asphalt layer 15 .

[0132] The hook 16 can be set in a semicircular shape, and the hook 16 is used to lift the cover plate 4 to facilitate subsequent maintenance inside the trench 1.

[0133] The above description is merely a preferred embodiment of the present invention and does not constitute any form of limitation to the present invention. Although the present invention has been disclosed as above with preferred embodiments, it is not intended to limit the present invention. Any technician familiar with this patent can make some changes or modifications to equivalent embodiments with equivalent changes using the above-mentioned technical contents without departing from the scope of the technical solution of the present invention. The implementation schemes in the above embodiments can also be further combined or replaced.
