[0002] Building energy consumption is increasing, particularly in building heating and cooling systems. To reduce building energy consumption, more and more new technologies are being used to lower the energy consumption of heating and cooling systems, such as underground energy structure technology.

[0003] Underground energy structure technology can establish heat exchange channels between buildings and underground soil, directly burying heat exchange pipes inside diaphragm walls, pile foundations, etc., forming an underground heat exchanger together with the underground engineering structure. This provides cooling for the building in summer and heating in winter, reducing the use of electrical equipment and effectively lowering building energy consumption. However, this technology requires simultaneous construction of diaphragm walls and pile foundations, resulting in high construction costs and complex procedures. Furthermore, the placement of heat exchange pipes within these load-bearing structures may affect their structural performance and jeopardize building safety.

[0004] Therefore, it is necessary to propose new measures to overcome the above-mentioned shortcomings. Summary of the Invention

[0035] This utility model provides a heat pipe wire bundle anchor rod. As a novel anchor rod, it not only anchors underground structures but also transfers underground heat through the excellent thermal conductivity of the heat pipe, thus playing a role in heat conduction. Specifically, as... Figure 1 The anchor bolt includes an anchor bolt body 7, a wire bundle 1, a heat pipe 4, and an anchor block 5.

[0036] The heat pipe 4 is axially installed inside the anchor rod body 7 and located on the central axis of the anchor rod body 7, extending along the length of the anchor rod body. The outer shell C of the heat pipe 4 is made of metal, and the interior has a liquid wick D and a vacuum chamber E, which is divided into an evaporation heat absorption section A, an insulation section F, and a heat dissipation and condensation section B.

[0037] The wire bundle 1 is composed of multiple strands of steel wire twisted together, axially arranged inside the anchor rod body 7, and evenly distributed around the outer periphery of the heat pipe 4. The ends of the wire bundle 1 are exposed at the ends of the anchor rod body 7 and are anchored by the anchor block 5.

[0038] Multiple isolation rings 2 are installed inside the anchor rod body 7. Each isolation ring 2 is a metal circular plate, perpendicular to the axial direction and evenly arranged along the axial direction, with a central hole and an outer peripheral hole. A heat pipe 4 is inserted into the central hole of the isolation ring 2, and a steel wire bundle 1 is inserted into the outer peripheral hole of the isolation ring 2. The diameter of the isolation ring 2 is equal to the inner diameter of the anchor rod body 7. The outer periphery of the isolation ring 2 is close to the inner wall of the anchor rod body 7, and is confined within the anchor rod body 7 by friction, or it can be directly fixed to the inner wall of the anchor rod body 7.

[0039] Multiple clamping rings 3 are installed inside the anchor rod body 7. Each clamping ring 3 is a metal circular plate, perpendicular to the axial direction and evenly arranged along the axial direction. Each clamping ring 3 has a central hole and an outer peripheral hole. The central hole of the clamping ring 3 corresponds axially to the central hole of the isolation ring 2. A heat pipe 4 is inserted into the central hole of the clamping ring 3, and a steel wire bundle 1 is inserted into the outer peripheral hole of the clamping ring 3. The diameter of the clamping ring 3 is smaller than the inner diameter of the anchor rod body 7.

[0040] The isolation rings 2 and clamping rings 3 are arranged alternately. The steel wire bundle 1 passes through the outer peripheral hole of the isolation ring 2, and its two ends pass through the outer peripheral holes of the two clamping rings 3 respectively and are tied.

[0041] The anchor bolt body 7 has an anchoring section 10 at its end, which is made of multiple strands of steel wire bundle 1 twisted together and threaded. The anchoring section 10 passes through the anchor block 5 with an opening, and the nut 6 is screwed into the anchoring section 10 and tightened to achieve the anchoring effect. In addition, the various isolation rings 2 and clamping rings 3 are connected as a whole by cross-arranged ribs 9.

[0042] The construction method of the above-mentioned heat pipe wire bundle anchor bolts, such as Figure 2 It has the following steps:

[0043] S1: Align multiple bundles of steel wires, straighten them, ensure that each bundle is of equal length, and tie them together at the ends in a circumferential manner to form a steel wire bundle 1.

[0044] S2: Repeat S1 to obtain multiple bundles of steel wire 1. Pass a sufficient number of bundles of steel wire 1 through the wires in the order of clamping ring 3-isolation ring 2-clamping ring 3, ensuring that there are no fewer than three clamping rings 3 and isolation rings 2.

[0045] S3: Pass the heat pipe 4 through the center hole of the clamping ring 3 and the isolation ring 2, and secure it. Ensure that the heat pipe 4 touches the top area of ​​the anchor rod 7, but does not exceed the anchoring end of the anchor rod 7.

[0046] S4: Apply lubricant to the center hole where the heat pipe 4 passes through the clamping ring 3 and the isolation ring 2 to ensure that the heat pipe can rotate at the center hole and prevent it from being broken by stress.

[0047] S5: Drill holes into the surrounding rock on the wall at the construction site, and clean the holes of any debris or mud and water. If the holes are wet, rinse them with clean water until clean water flows out. For several holes, use an air compressor to clean them.

[0048] S6: With the anchor head at the bottom of the hole, slide the prepared anchor rod into the pre-drilled hole.

[0049] S7: Insert the grouting pipe tightly into the borehole, and anchor the anchor rod by grouting. Set the anchor block 5 and nut 6 outside the borehole for pull-out anchoring of the anchor rod.

[0050] Anchoring methods:

[0051] M1: Weld the anchor joint end 10 and thread it to facilitate the installation of nut 6.

[0052] M2: Before tightening nut 6, perform a tensile test on the anchor rod and observe whether the wire bundle is loose to ensure the stability of the anchor rod.

[0053] M3: Tighten nut 6 to the maximum extent and check the anchoring stability of the entire anchoring device.

[0054] M4: Apply cement grout or a false external protective cover to the exposed portion of the anchorage joint end 10 to protect the anchorage end.

[0055] Specifically, bottom-hole grouting is used to ensure the grout in the rock strata is full. The anchor grouting pump is adjusted to ensure it is securely connected and operating normally, meeting the required grouting pressure. The grouting pipe of the anchor grouting pump is inserted into the pre-set bottom of the hole, and the pump is turned on. Note that the grouting pipe needs to be slowly pulled out while grouting. The tail of the anchor rod is inserted into the grouted hole with the bottom facing out. The head of the anchor rod is fixed to one side of the underground structure using anchor block 5 and nut 6 for stability. After the grout has solidified, the grouting pipe is pulled out.

[0056] After the underground space 8 is completed and put into use, the structure of this utility model can play a heat exchange role:

[0057] When the indoor temperature is high, the liquid at the bottom of the heat pipe inside the anchor rod at the top of the underground space building is heated, causing it to evaporate. The vapor reaches the condensation section at the top of the heat pipe, where it undergoes a condensation and heat dissipation process, transferring the heat to the rock layer. The condensed liquid is subject to gravity and automatically flows back to the evaporation section at the bottom of the heat pipe, where it is heated and evaporates again. This continuous cycle transfers the heat of the underground space to the surrounding rock, achieving the purpose of heat dissipation for the underground space building.

[0058] When the indoor temperature is low, the coolant at the bottom of the anchor heat pipes on both sides of the underground space evaporates due to the high temperature of the underground rock strata, carrying the heat into the underground space building. When the steam reaches the top, it is condensed back into coolant and flows back to the bottom along the heat pipe wall, continuously circulating to carry the heat of the rock strata into the underground space building, thereby achieving the effect of heating the underground space building.

[0059] The above-described specific examples are for illustrative purposes only and are not intended to limit the scope of this invention. Those skilled in the art to which this invention pertains can make various simple deductions, modifications, or substitutions based on the concept of this invention.
