Description

Technical Field

[0001] The utility model belongs to the field of large-scale cross-season heat storage, in particular to an anti-seepage and heat preservation system of a large-scale cross-season heat storage concrete pool. Background Art

[0002] Inter-seasonal heat storage technology is a technology that stores the heat energy collected during the non-heating season in a large-capacity heat storage body, extracts it during the heating season, and inputs it into the heating network for heating. It can solve the problem of seasonal mismatch between heat sources and heat demand, and provide a new technical route for replacing coal with clean energy.

[0003] According to relevant research on inter-seasonal heat storage, the larger the volume of the inter-seasonal heat storage body, the lower the heat storage cost per unit volume. If large-scale inter-seasonal heat storage is carried out, the investment and construction costs of inter-seasonal heat storage will be significantly reduced, and a low-carbon heating model that can truly be commercially operated will be realized.

[0004] At present, large-scale inter-seasonal heat storage bodies mostly use large excavated pools. However, large excavated pools have the disadvantages of large floor space and high heat loss from the top cover. Therefore, the utility model provides a concrete pool anti-seepage and heat preservation system suitable for large-scale inter-seasonal heat storage. Utility Model Content

[0005] The utility model aims to solve the problems of anti-seepage and thermal insulation of large-scale cross-seasonal heat storage water bodies and the problem of large heat loss on the top of large excavated water pools, thereby providing an anti-seepage and thermal insulation system for large-scale cross-seasonal heat storage concrete water pools, which greatly reduces the footprint, improves the efficiency of the heat storage system, avoids easy disturbance of the temperature layer of the excavated water pool, and avoids water accumulation on the top.

[0006] To achieve the above-mentioned purpose of the utility model, the utility model provides a large-scale cross-season heat storage concrete water pool anti-seepage insulation system, characterized in that it includes a water pool, a bottom anti-seepage layer, a cushion layer, an air insulation layer, a top anti-seepage insulation layer, a side wall anti-seepage insulation layer, and a side wall anti-seepage layer; the water pool includes a bottom plate, a side wall, a partition wall, a pillar, a support plate, and a top plate, all of which are reinforced concrete structures. The water pool is divided into a number of compartments by partition walls, and a row of support columns is arranged in the middle of each water pool compartment along the length direction. A support plate is arranged on the top of the support column to form a plate-column structure with the concrete top plate of the water pool; an air insulation layer is arranged above the water surface and below the water pool top plate; a top anti-seepage insulation layer is arranged on the outer side of the top plate, and a side wall anti-seepage insulation layer is arranged on the upper part of the outer side of the side wall; the top anti-seepage insulation layer includes a vapor barrier layer, a slope layer, an insulation layer, a leveling layer, an anti-seepage layer, and a protective layer arranged from the inside to the outside. The side wall anti-seepage and heat-insulating layer comprises a vapor barrier layer, a heat-insulating layer, a leveling layer, an anti-seepage layer and a protective layer which are arranged from the inside to the outside.

[0007] Furthermore, the pool depth is 5m-20m, the width of a single compartment is 10m-15m, and the capacity of a single compartment is 5000m 3 -3×10 4 m 3 .

[0008] Furthermore, the slope of the slope finding layer is 1%-2%.

[0009] Furthermore, the thickness of the air insulation layer is 10cm-30cm.

[0010] Furthermore, the protective layer is a paint protective layer, a fine stone concrete protective layer or a block material protective layer.

[0011] Furthermore, the side wall anti-seepage and thermal insulation layer is replaced by a vapor barrier layer and a protective layer.

[0012] Furthermore, it also includes a photovoltaic bracket and a solar photovoltaic component. The photovoltaic bracket and the solar photovoltaic component are arranged on the upper side of the top plate of the pool to construct a photovoltaic power generation system.

[0013] Compared with the existing anti-seepage and thermal insulation system of excavated pools, the positive effects of the utility model are:

[0014] (1) The pool adopts concrete structure, which greatly reduces the floor space and is particularly suitable for areas with limited land use.

[0015] (2) The pool wall, bottom plate and top plate form a closed system with no open space on the top, which greatly reduces the heat dissipation on the top and improves the efficiency of the heat storage system.

[0016] (3) The water pool is divided into strips, and each water pool can be independently operated and separated into different temperature zones, thus avoiding the disadvantage that the temperature layer of the excavated water pool is easily disturbed.

[0017] (4) An air insulation layer is set above the water surface to further reduce the heat dissipation at the top and improve the efficiency of the heat storage system.

[0018] (5) A slope leveling layer is set on the top surface of the pool to effectively drain atmospheric precipitation and avoid the problem of water accumulation on the top.

[0019] (6) The large-scale hot water storage tank occupies a large area, and a photovoltaic power generation system is installed on the top, which effectively utilizes the project land. BRIEF DESCRIPTION OF THE DRAWINGS

[0027] In order to better understand the purpose, structure and function of the utility model, the following is a further detailed description of the anti-seepage and thermal insulation system of a large-scale cross-seasonal heat storage concrete water pool of the utility model in conjunction with the accompanying drawings.

[0028] The utility model is suitable for a concrete water pool anti-seepage and thermal insulation system for large-scale cross-seasonal heat storage, comprising: a water pool 1, a bottom anti-seepage layer 8, a cushion layer 9, an air thermal insulation layer 10, a top anti-seepage and thermal insulation layer 11, a side wall anti-seepage and thermal insulation layer 12, and a side wall anti-seepage layer 13.

[0029] Pool 1 is a strip-divided concrete pool. The size and capacity of a single pool should be determined according to the needs of the heat storage system. For a large-scale cross-seasonal heat storage system, the pool depth should be 5m-20m, the single-cell width should be 10m-15m, and the single-cell capacity should be 5000m. 3 -3×10 4 m 3 .

[0030] The pool includes a bottom plate 7, a side wall 2, a partition wall 3, a support plate 4, a support plate 5, and a top plate 6, all of which are reinforced concrete structures. The pool is divided into a plurality of compartments by the partition wall. A row of support columns is arranged in the middle of each compartment along the length direction. A support plate is arranged on the top of the support column to form a plate-column structure with the concrete top plate of the pool. An air insulation layer 10 is arranged above the water surface and below the top plate of the pool. The thickness of the air insulation layer 10 is preferably 10cm-30cm.

[0031] The concrete of the pool should be impermeable concrete. The impermeability grade is determined according to the depth of the water body in the pool and the depth of the groundwater outside the pool, and should not be lower than P8. The thickness of the pool bottom plate and side wall is determined according to the load and design conditions. The temperature load and temperature cracks should be considered in the analysis and calculation. For pools with a depth greater than 5m, the side walls and partitions should adopt variable or trapezoidal cross-sections to reduce the amount of work and reduce the cost.

[0032] A top anti-seepage insulation layer 11 is provided on the outside of the top plate 6, and a side wall anti-seepage insulation layer 12 is provided on the upper part of the outer side of the side wall. The top anti-seepage insulation layer 11 includes a vapor barrier layer 14, a slope layer 15, an insulation layer 16, a leveling layer 17, an anti-seepage layer 18, and a protective layer 19 arranged from the inside to the outside.

[0034] On the outside of the top plate 6, a slope layer is arranged on the vapor barrier 14. The slope of the slope layer 15 is preferably 1%-2% to discharge the top rainwater and ice and snow melt water. The slope layer material is preferably selected from lightweight materials, such as pool mud perlite, etc., to reduce the load.

[0035] On the top surface of the pool, an insulation layer 16 is arranged above the slope layer 15. The insulation material and thickness of the insulation layer can be determined according to the results of the system heat storage efficiency calculation. On the side of the pool, an insulation layer 16 is arranged outside the vapor barrier 14. The thickness and height of the insulation layer 16 are determined according to the results of the heat storage system analysis and calculation.

[0036] When it is calculated that the side of the pool does not need an insulation layer 16, a protective layer 19 is provided on the vapor barrier layer 14. The protective layer 19 can be a paint protective layer, a fine stone concrete protective layer or a block material protective layer. At this time, the side wall anti-seepage layer 13 includes the vapor barrier layer 14 and the protective layer 19.

[0037] In the area where there is an insulation layer on the top and side of the pool, a cement mortar leveling layer 17 is arranged above the insulation layer, and the thickness is preferably 20mm.

[0038] In the area where there is an insulation layer on the top and side of the pool, an anti-seepage layer 18 is laid above the leveling layer. The anti-seepage layer 18 is a waterproof roll material. The waterproof roll material should be a weather-resistant material, which is determined according to the climatic conditions of the project location. If the project location is a high-latitude area, a low-temperature resistant material should be selected.

[0039] In the area where there is a thermal insulation layer on the top and side of the pool, a protective layer 19 is arranged on the anti-seepage layer 18, which can be a paint protective layer, a fine stone concrete protective layer or a block material protective layer.

[0040] Photovoltaic brackets and solar photovoltaic modules are constructed on the upper side of the pool roof to build a photovoltaic power generation system. The model and layout of the photovoltaic modules are designed according to the specific project.

[0041] The specific construction process of this utility model:

[0042] (1) Based on the analysis and calculation results of the heat storage system, the volume and burial depth of the water pool are determined, and the water pool compartment layout plan is determined, and the strip-divided reinforced concrete water pool 1 is constructed.

[0043] (2) Before constructing the pool bottom plate 7, a cushion layer 9 is laid, and a bottom anti-seepage layer 8 is laid on the cushion layer 9.

[0044] (3) Construct the pool bottom plate 7, side wall 2, support 4, partition wall 3, support plate 5 and top plate 6 in sequence.

[0045] (4) A waterproof membrane vapor barrier layer 14 is laid on the top plate 6 and the side wall 2 of the pool. The waterproof membrane should be made of high temperature resistant material.

[0046] (5) A slope leveling layer 15 is constructed on the top surface of the pool to drain rainwater and melted ice and snow.

[0047] (6) A thermal insulation layer 16 is constructed on the upper part of the slope layer 15 on the top surface of the pool and on the outside of the side wall 2.

[0048] (7) A cement mortar leveling layer 17 is constructed in the areas where the thermal insulation layer 16 is provided on the top and side surfaces of the pool.
