Description

Technical Field

[0001] This invention belongs to the field of road construction technology and relates to a construction device and construction method for an inorganic thermal pipeline snow melting system. Background Technology

[0002] Most parts of my country experience varying degrees of snow and ice weather every year. Accumulated snow and ice on roads severely impact traffic flow and driving safety, making snow and ice removal a major concern. Currently, there are two main types of snow and ice removal methods: mechanical removal and melting. Mechanical removal requires snowfall and has a certain delay, while melting mainly involves spreading chemical agents on the road surface to lower the freezing point of the snow and ice, causing them to melt. However, melting agents have a significant impact on roadside green belts and groundwater after the snow and ice have melted.

[0003] To address the environmental damage caused by snow-melting agents and the delays in mechanical snow removal, and to improve the service life of roads, a new snow-melting system device and method are needed. Summary of the Invention

[0004] To address the problems existing in the prior art, a construction device and construction method for an inorganic thermal pipeline snow melting system are provided.

[0005] The technical solution adopted by this invention to solve its technical problem is:

[0006] This invention proposes a construction device for an inorganic thermal pipeline snow melting system, including a road, which consists of a pavement layer, a road base layer and a soil layer from top to bottom. The pavement layer has grooves, and a deep hole is formed at one end of each groove, extending down to the soil layer.

[0007] It also includes an inorganic heat pipe, which comprises a condensing section, an insulating section, and an evaporating section from top to bottom; wherein the condensing section is located in a groove, and the insulating section and the evaporating section are both located in a deep hole.

[0008] It also includes a positioning ring for positioning the inorganic heat pipe and a guiding mechanism. The positioning ring is equidistantly sleeved on the evaporation section, and the guiding mechanism is detachably inserted into the deep hole. The inorganic heat pipe is inserted into the guiding mechanism and slides downward until it is installed in the deep hole.

[0009] It also includes backfill molds for filling the grooves.

[0011] Preferably, the latching assembly includes latches connected to both sides of the fan-shaped surface. The latches have a U-shaped structure, and when the two latches are engaged, the positioning ring is frustum-shaped.

[0012] Preferably, the guiding mechanism includes a hollow frustum, the bottom of which is connected to an insertion tube, and the insertion block is inserted into a deep hole; it also includes a connecting insertion hole and a slot, the insertion hole and slot passing through the frustum and the insertion tube, and the inorganic heat pipe being slidably connected to the insertion hole and the slot; the side wall of the hollow frustum has at least one opening for placing a positioning ring.

[0013] Preferably, the backfill mold includes a steel frame, with a steel plate connected to the bottom of the steel frame, and the steel plate having a backfill slot adapted to the groove; handles are symmetrically connected to the upper surface of the steel frame.

[0014] This invention also proposes a construction method for an inorganic thermal pipeline snow melting system construction device, comprising the following steps:

[0015] S1: Locating and setting out the lines to determine the construction location;

[0016] S2: A groove is made at the location of the road surface layer, and a deep hole is made at one end of the groove, which is drilled down to the underground constant temperature layer.

[0017] S3: Deep hole inspection. If the inspection is successful, proceed to the next construction step. If the inspection fails, repeat step S2.

[0018] S4: Install the vertical end of the inorganic heat pipe into the deep hole. During the installation process, ensure that the inorganic heat pipe is centered and vertical. Continue to lower the inorganic heat pipe until the horizontal end of the inorganic heat pipe is embedded in the groove.

[0019] S5: Pour cement mortar into the deep hole until the bottom of the insulation section in the inorganic heat pipe is reached. Fill the deep hole with insulation material until the top of the insulation section is reached. Fill the groove with modified emulsified asphalt and asphalt sand and compact it until the road surface is smooth.

[0020] Preferably, in S4, to ensure that the inorganic heat pipe is centered and vertical during installation, a guide mechanism is used. The guide mechanism is inserted into the deep hole.

Detailed Implementation

[0036] Embodiments of the present invention are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0037] like Figure 1-8 As shown in the figure, this embodiment proposes a construction device for an inorganic thermal pipeline snow melting system, which includes:

[0038] A highway consists of a pavement layer, a road base layer, and a soil and rock layer from top to bottom. The soil and rock layer contains an underground constant-temperature layer. The pavement layer and road base layer together are 10m long, and the bottom of them is a soil and rock layer.

[0039] Several grooves 2 are made in the road surface layer. The grooves 2 are equally spaced and parallel, and the distance between each groove 2 is controlled at about 0.4m. The size of the groove 2 is 5m*5cm and the depth of the groove 2 is 5cm. A deep hole 3 is opened at one end of the groove 2. The bottom of the deep hole 3 reaches the soil layer. Specifically, an 8cm drill bit is used for drilling, and the final hole depth should reach 14m.

[0040] Inorganic heat pipe 1, from top to bottom, includes a condensing section, an adiabatic section, and an evaporating section. The condensing section is located in the groove 2, and the adiabatic section and the evaporating section are both located in the deep hole 3. Specifically, the inorganic heat pipe 1 is L-shaped, with the condensing section at its horizontal end and an overall length of 2.8m, and the adiabatic section plus the evaporating section at its vertical end and an overall length of 13.5m.

[0041] The base tube of inorganic heat pipe 1 should be a cold-drawn (rolled) seamless steel pipe, and the carbon steel pipe should be selected according to the provisions of "Seamless Steel Pipes for Low and Medium Pressure Boilers" (GB3087); the heat transfer capacity should be ≥170W / piece, the axial temperature difference should be less than 2°C, and the temperature uniformity should be good; the inner and outer walls should be reliably protected against corrosion. The outer wall corrosion protection adopts two oils and one cloth. The epoxy asphalt paint used should meet the requirements of "Epoxy Asphalt Anticorrosion Coating" (GB / T27806), and the alkali-resistant glass fiber mesh should meet the requirements of "Alkali-resistant Glass Fiber Mesh" (JC / T841). The thickness of the anticorrosion layer plus the paint film should be >0.2mm, and the paint film thickness of the condensing section should be >0.1mm. The outer anticorrosion surface should be free of bubbles, the glass fiber cloth should be evenly wrapped without wrinkles, burrs, or other defects, the coating should be uniform, and the adhesion should be firm. The inner wall should be treated with a chemical film-forming method; the angle requirement for the condensing section of the inorganic heat pipe is 1°~3°. The specific heating principle of the inorganic heat pipe 1 is as follows: The inorganic heat pipe 1 consists of a shell, core mesh, end caps, and sealing tubes. According to its operation, it can be divided into three parts: evaporation section, insulation section, and condensation section. The inorganic heat pipe 1 is filled with a saturated working fluid. The selection of the working fluid depends on the environment in which it is used. The freezing point must be lower than the lowest temperature of the environment. Common choices include Freon, methanol, ethanol, and water. The heat from the constant temperature layer under the soil layer is transferred to the evaporation section of the heat pipe. The heat is then transferred to the working fluid through the pipe wall. The working fluid vaporizes after being heated. Due to the pressure change, the vaporized working fluid passes through the insulation section to the condensation section. In the condensation section, due to the low temperature caused by the ice and snow covering the road surface, the vaporized working fluid undergoes a phase change and liquefies, thereby releasing heat to dissolve the ice and snow on the road. The liquefied working fluid returns to the evaporation section through the capillary action of the core mesh, completing one working cycle, thus realizing the transfer of energy.

[0042] It also includes a positioning ring 4 for positioning the inorganic heat pipe 1 and a guide mechanism 5. The positioning ring 4 is equidistantly sleeved on the evaporation section, and the guide mechanism 5 is detachably inserted into the deep hole 3. During the installation process, the inorganic heat pipe 1 is inserted into the guide mechanism 5 and lowered until the vertical end is installed in the deep hole 3.

[0043] Specifically, the positioning ring 4 is made of flexible material, such as plastic or flexible metal sheet. The positioning ring 4 includes a fan-shaped surface 43 with a thickness of 1.5cm. Several grouting ports 41 are provided on the fan-shaped surface 43. The grouting ports 41 are used for the downward flow of grout during grouting. The fan-shaped surface 43 has a locking assembly 42 on both sides. The locking assembly 42 can be connected by Velcro, snap fastener, or claw 421 to achieve detachable connection between the two sides of the fan-shaped surface 43. In this embodiment, the claw 421 is preferred. The snap fastener in this embodiment includes claws 421 connected to both sides of the fan-shaped surface 43. The claws 421 have a U-shaped structure. The claws 421 can be locked together. When the two claws 421 are locked together, the positioning ring 4 is in the shape of a frustum. At this time, the bottom diameter of the positioning ring 4 is 3.2cm. With the same diameter as inorganic heat pipe 1, the top of positioning ring 4 is 7cm. Positioning ring 4 is equidistantly fitted on inorganic heat pipe 1. The top of positioning ring 4 is supported in deep hole 3, so that inorganic heat pipe 1 always remains vertical and prevents it from deviating.

[0044] The guiding mechanism 5 includes a hollow frustum 51, with a tube 52 connected to the bottom of the hollow frustum 51. The tube 52 is inserted into the deep hole 3. It also includes a connected insertion hole 54 and a slot 55, which pass through the frustum and the tube 52. The inorganic heat pipe 1 is slidably connected to the insertion hole 54 and the slot 55. In this embodiment, the insertion hole 54 is a non-uniform diameter insertion hole 54, with a diameter of 3.5cm on the top surface of the hollow frustum 51, a diameter of 7cm on the bottom surface, a slot width of 3.5cm, an inner diameter of 7cm for the tube 52, and an outer diameter of 8cm for the tube 52, allowing it to be inserted into the deep hole 3. In actual construction, the inorganic heat pipe 1 is hoisted using a three-point method with a crane. During the installation of the inorganic heat pipe 1, its vertical end is aligned with the insertion hole 54, and then the inorganic heat pipe 1 is lowered so that its vertical end slides downward within the insertion hole 54. At least one opening 53 for placing the positioning ring 4 is opened on the side wall of the hollow truncated cone 51. In this embodiment, two openings 53 are opened to facilitate the placement of the positioning ring 4 from multiple angles. During the lowering of the inorganic heat pipe 1, the positioning ring 4 is placed on the inorganic heat pipe 1 through the opening 53. The inorganic heat pipe 1 is lowered, and after a certain distance, the inorganic heat pipe 1 is placed again through the opening 53. No positioning ring 4 is set within 1m below the top of the road surface layer until the inorganic heat pipe 1 is installed. After the installation is completed, the guide mechanism 5 can be pulled out from the deep hole 3 and used again at the next construction site.

[0045] It also includes a backfill mold 6 for filling the groove 2. The backfill mold 6 includes a steel frame 61, with a steel plate 62 connected to the bottom of the steel frame 61. The steel plate 62 has a backfill slot 63 that matches the groove 2. In this embodiment, the steel frame 61 is a rectangular structure with a length of 4m and a width of 50cm. The backfill slot 63 is a rectangular structure with the same size as the groove 2. Handles 64 are symmetrically connected to the upper surface of the steel frame 61. Specifically, the handles 64 are located in the two width directions of the steel frame 61. According to the construction requirements, after the inorganic heat pipe 1 is installed, the pit needs to be backfilled with asphalt sand. Because the slot is small and shallow, backfilling is difficult and can easily lead to incomplete backfilling and pollution of the surrounding completed asphalt pavement. Therefore, in order to ensure the backfilling quality, this backfill mold 6 is used, which facilitates construction, produces an aesthetically pleasing finished product, and ensures the backfilling quality.

[0046] This invention also proposes a construction method for an inorganic thermal pipeline snow melting system construction device, comprising the following steps:

[0047] S1: Locating and setting out the lines to determine the construction location;

[0048] After the flexible base course of the road surface is laid, the surveying station uses the layout diagram to measure and mark the positions of the deep holes and inorganic heat pipe 1. The deviation of the plane position should be controlled within 1cm.

[0049] S2: A groove 2 is opened at the location of the road surface layer layout until the road base layer is reached. A deep hole 3 is opened at one end of the groove 2 and drilled to the underground constant temperature layer.

[0050] Groove 2 is created using a QG500 high-efficiency grooving machine. Groove 2 is a 5*5cm rectangular groove. When creating groove 2, a sponge should be used to treat the grout to reduce contamination of the flexible substrate. After cutting, groove 2 is cleaned manually to ensure the groove depth meets the requirement of 5cm, the bottom is flat, and the slope is at least 1°. The bottom of the groove must be free of sharp stones and debris to avoid affecting the pipeline. After cleaning, a self-inspection is conducted. Once the self-inspection is passed, it is submitted to the supervising engineer for inspection.

[0051] After the construction of groove 2 is completed, drilling of deep hole 3 will commence. A Zhigao 452H drilling rig will be used on site, employing dry drilling. The rig is equipped with a cuttings collection system to minimize road surface pollution. Deep hole 3 is located at a lower elevation on the road's cross slope. Before drilling, the rig will be centered, and a spirit level will be used to check the verticality of the drill frame. To ensure the effectiveness of subsequent grouting and polyurethane filling, an 8cm drill bit will be used, with the hole depth exceeding the vertical length of the heat pipe by 0.5m, ultimately requiring a hole depth of 14m. During drilling, rubber pads will be placed under the drill rig tracks to prevent damage to groove 2, and tarpaulins will be laid to reduce road surface pollution.

[0052] S3: Deep hole 3 inspection. If the inspection is qualified, proceed to the next construction step. If the inspection is unqualified, repeat step S2.

[0053] After the completion of Deep Hole 3, the hole depth was checked using a measuring rope to ensure it met design and specification requirements. Following hole drilling, a portion of the boreholes were selected for ground temperature investigation using a digital thermometer with a transmission line length of 13.5m. Both ambient and borehole temperatures were measured. The results showed that at an ambient temperature of 26.6℃, the ground temperature was 14.9℃. Feedback from the design unit confirmed that this met design requirements, and the next step of construction could proceed. For boreholes that did not meet design requirements, step S2 was repeated, and the measurement was re-tested.

[0054] S4: Install the vertical end of the inorganic heat pipe 1 into the deep hole 3. During the installation process, ensure that the inorganic heat pipe 1 is centered and vertical. Continue to lower the inorganic heat pipe 1 until the horizontal end of the inorganic heat pipe 1 is embedded in the groove 2.

[0055] Before lowering the inorganic heat pipe 1, apply emulsified asphalt around the groove 2 and lay a layer of asphalt sand at the bottom of the groove. Use a 32mm diameter steel pipe to press the groove, ensuring that the inorganic heat pipe 1 is in close contact with the bottom asphalt sand. During the hoisting process, take care to protect the surface anti-corrosion layer of the inorganic heat pipe 1. Replace or repair any damaged layers. Vertically insert the inorganic heat pipe 1 into the deep hole 3 to the specified depth. After fixing, the allowable error in the horizontal position of the inorganic heat pipe 1 is ±10mm, and the allowable deviation in elevation is ±5mm. The inorganic heat pipe 1 is installed using a three-point hoisting method.

[0056] In S4, to ensure that the inorganic heat pipe 1 is centered and vertical during installation, a guide mechanism 5 is used. The guide mechanism 5 is inserted into the deep hole 3. During the lowering process, the vertical end of the inorganic heat pipe 1 is inserted into the guide mechanism 5 and then lowered. During the lowering process, the positioning ring 4 is sleeved on the inorganic heat pipe 1. The positioning ring 4 is sleeved on the inorganic heat pipe 1 at equal intervals, and is only sleeved on the evaporation section.

[0057] S5: Pour cement mortar into deep hole 3 up to the bottom of the insulation section in inorganic heat pipe 1. Fill deep hole 3 with insulation material. Polyurethane foam, preferably used in-situ, should be used to form the insulation material. The thermal conductivity of the insulation material should be ≤0.025 W / (m·K). If other insulation materials are used, they should meet the thermal conductivity requirements. Continue the insulation material up to the top of the insulation section. Fill groove 2 with modified emulsified asphalt and asphalt sand, compacting it until the road surface is smooth.

[0058] In S5, backfilling of groove 2 is carried out using backfill mold 6. Backfill mold 6 is placed above groove 2, and modified emulsified asphalt and asphalt sand are laid inside backfill mold 6. Modified emulsified asphalt used for coating the inner wall of groove 2 and filling gaps should meet the technical standards for modified emulsified asphalt in JTGF40-2004 "Technical Specification for Construction of Highway Asphalt C) Pavement". Subsequently, modified emulsified asphalt and asphalt sand are scraped and filled into the interior of groove 2. During the filling process, compaction tools are used to ensure that the interior of groove 2 is backfilled densely.

[0059] Specifically, grouting is first performed in the evaporation section. After the inorganic heat pipe 1 condensation section is fixed in the groove 2 and it is ensured that the inorganic heat pipe 1 is in close contact with the groove 2, cement mortar is backfilled into the evaporation section from bottom to top (the backfilling pressure should be 0.6~1MPa) to 1m below the deep hole 3, ensuring compaction. The cement mortar is preferably the grouting material for the precast box girder ducts, with a water-cement ratio of 0.28. The pressure reduction equipment used is a duct intelligent pressure reduction device. The duct intelligent pressure reduction device has good fluidity and expansion effect, ensuring that the banana leaf filling is dense while meeting the strength requirements of the design.

[0060] Following this, the insulation section will be constructed. The insulation section (the upper 1m of the vertical section) will use on-site polyurethane foam insulation. Hollow areas, incomplete foaming, shrinkage, breakage, insufficient density, and a soft, sponge-like consistency are strictly prohibited. The volumetric filling rate must be greater than 98%, the density greater than 35 kg / m³, and the thermal conductivity ≤ 0.025 W / (m·K) (refer to GB3399 for specific requirements). Before construction, polyurethane experiments will be conducted using 8cm and 3.2cm diameter PVC plastic pipes to simulate actual conditions. After cutting and compacting, polyurethane filling work can proceed.

[0061] Finally, the condenser section groove 2 was backfilled and repaired. The gap between the condenser section of inorganic heat pipe 1 and the groove was backfilled and compacted using modified emulsified asphalt and asphalt sand. The asphalt sand mix ratio is shown in Table 3.1 below:

[0062] Table 3.1 Mix Proportions for AC-5 Asphalt Concrete Production

[0063]

[0064] The backfilling of asphalt sand is carried out using backfill mold 6. Since the loose paving coefficient of asphalt sand is 1.25, the filling height should be 1cm higher when backfilling asphalt sand. Then, a small asphalt compactor is used for compaction to ensure the quality of backfilling.

[0065] Although embodiments of the invention have been shown and described, those skilled in the art will understand that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the claims and their equivalents.
