Description

Technical Field

[0001] This utility model relates to thermal storage structures, specifically to a honeycomb-shaped underground thermal storage tank structure. Background Technology

[0002] The statements herein provide only background information related to this invention and do not necessarily constitute prior art.

[0003] Currently, underground thermal storage ponds mostly adopt rectangular or polygonal designs. During construction, traditional concrete support piles, water-stop curtains, and internal supports are often used in combination for foundation pit excavation, followed by internal structure backfilling.

[0004] While existing thermal storage tank structures can perform basic thermal storage functions, they present the following technical problems regarding thermal stress concentration:

[0005] Because of the bending angles in the walls of rectangular or polygonal structures, the bending angles are affected by the temperature of the internal heat storage medium, resulting in significant thermal stress concentration in the walls of the rectangular or polygonal structures. To improve the service life of the structural components, larger dimensions and a higher steel reinforcement content are required. Utility Model Content

[0006] The purpose of this invention is to provide a honeycomb-shaped underground thermal storage tank structure that can at least solve one of the above-mentioned technical problems.

[0007] To achieve the above objectives, this utility model proposes a honeycomb-shaped underground thermal storage tank structure, comprising several circular thermal storage tank units arranged in a honeycomb pattern, several support piles evenly distributed on the side walls of the circular thermal storage tank units, a cement-soil wall covering the support piles, and a capping plate installed on the top of the support piles.

[0008] Further configured, the circular thermal storage tank unit includes a first thermal storage tank unit located at the center.

[0009] Further configured, the second thermal storage tank units are distributed in a cross shape along the first thermal storage tank unit.

[0010] A further configuration involves setting up a third thermal storage unit outside the second thermal storage unit.

[0011] Further configuration involves setting the first section of the sidewall of the circular thermal storage tank unit on the inner side of the unit.

[0012] A further configuration is provided where a second sidewall of the thermal storage tank unit is located below the first sidewall of the thermal storage tank unit and on the inner sidewall of the circular thermal storage tank unit.

[0013] Further configuration involves setting a first excavation pit baseline at the bottom of the individual thermal storage tank.

[0014] Further configuration: the bottom line of the first excavation pit is flush with the bottom of the first section of the side wall of the thermal storage tank unit.

[0015] Further, a second excavation baseline is set at the bottom of the individual thermal storage tank.

[0016] Further configuration: the bottom line of the second excavation pit is flush with the bottom of the second section of the side wall of the thermal storage tank unit.

[0017] The beneficial effects of one or more of the above technical solutions:

[0018] The circular thermal storage tank, supporting piles, and cement-soil walls involved in this utility model are all arranged in a honeycomb pattern, which makes full use of geometric advantages to evenly distribute external forces, reduce thermal stress concentration, and overcome the disadvantage of large structural size and reinforcement caused by temperature stress when the components are of the same size.

[0024] The specific implementation of this embodiment will now be described with reference to the accompanying drawings.

[0025] Reference Figure 1This utility model proposes a honeycomb-shaped underground thermal storage tank structure, including several circular thermal storage tank units 1 arranged in a honeycomb pattern. The honeycomb arrangement fully utilizes geometric advantages to evenly distribute external forces and reduce thermal stress concentration. Several support piles 2 are evenly distributed on the side walls of the circular thermal storage tank unit 1. The support piles 2 are not limited to steel pipe support piles, steel profile support piles, prestressed pipe piles, concrete piles, etc., but are preferably steel pipe support piles. The support piles 2 are covered with a cement-soil wall 3. A capping plate 4 is set on the top of the support piles 2. The capping plate 4 is made of reinforced concrete. All support piles 2 are anchored into the capping plate 4. The capping plate 4 has reserved openings at the location of the thermal storage tank unit 1, which divides the entire thermal storage tank into multiple thermal storage tank units 1. The arrangement can be a 3×3 honeycomb arrangement. The net distance between the thermal storage tank units 11 is 3-5m to ensure uniform heat distribution.

[0026] The circular thermal storage tank unit 1 includes a first thermal storage tank unit 5 located at the center, second thermal storage tank units 6 distributed in a cross shape along the first thermal storage tank unit 5, and a third thermal storage tank unit 7 located outside the second thermal storage tank unit 6. The thermal storage tank unit 1 adopts a cylindrical reinforced concrete structure, and the diameter of the cylinder can be selected according to the site and volume requirements.

[0027] A first section of sidewall 8 is provided inside the circular thermal storage tank unit 1. A second section of sidewall 9 is provided below the first section of sidewall 8 and located on the inner sidewall of the circular thermal storage tank unit 1. The first and second section of sidewalls enclose the concrete of the cement-soil wall 3 to further increase its strength.

[0028] A first excavation baseline 10 is set at the bottom of the thermal storage tank unit 1, flush with the bottom of the first section of the side wall 8 of the thermal storage tank unit 1. A second excavation baseline 11 is set at the bottom of the thermal storage tank unit 1, flush with the bottom of the second section of the side wall 9 of the thermal storage tank unit 1. The setting of the first excavation baseline 10 and the second excavation baseline 11 facilitates the positioning of the height of the first section of the side wall 8 and the second section of the side wall 9 of the thermal storage tank unit 1.

[0029] The construction process involves the following steps:

[0030] Step 1: Construct all cement-soil mixing walls 3, and insert support piles 22 while the cement-soil mixing walls 3 are still in a fluid state.

[0031] Step 2: The concrete capping plate 44 at the top of the construction piles must cover the tops of all the support piles 22.

[0032] Step 3, as follows Figure 2 As shown, the first batch of thermal storage tank units 15 are constructed first, then the thermal storage tank units 16 are constructed from the inside out, and finally the corner thermal storage tank units 17 are constructed.

[0033] Furthermore, thermal storage tank units 15, 16, and 17 were all constructed using the reverse construction method, such as... Figure 3 As shown, the construction of the thermal storage tank unit 1 includes the following steps:

[0034] Step 1: Excavate the soil to the bottom line 10 of the first excavation pit of the thermal storage tank unit 1, with an excavation height of 4-5m, preferably 5m.

[0035] Step 2: Construct the first section of the side wall 88 of the single thermal storage tank, with a side wall thickness of 400-600mm, preferably 500mm.

[0036] Step 3: Excavate the soil to the bottom line 11 of the second excavation pit of the thermal storage tank unit 1, with an excavation height of 4-5m, preferably 5m.

[0037] Step 4: Construct the second section of the side wall 99 of the thermal storage tank unit. The side wall thickness is 400-600mm, preferably 500mm.

[0038] Step 5: Construct the remaining structural components of the thermal storage tank unit 1.
