[0003] Hydropower stations located in high altitude areas of the plateau have severe climate characteristics such as large temperature difference, strong ultraviolet rays, cold and dry climate, frequent freezing and thawing, and long winter break.

[0027] A concrete pier 2 is directly cast integrally on the structural roof slab 1, and an embedded part 5 is arranged on the top surface of the concrete pier 2; a lead-out tower 3 is installed above the embedded part 5 and fixed with bolts 4 and the embedded part 5; a waterproof structure 6 is laid on the surface where the concrete pier 2 and the structural roof slab 1 intersect.
[0028] Therefore, the utility model provides a plateau high altitude outlet tower structure with a roof waterproof node structure. The outlet tower is not directly fixed on the reinforced concrete roof, but by pouring a concrete pier 2 on the structural roof floor 1, and installing the outlet tower 3 on the concrete pier 2, thereby reducing the adverse effect of the outlet tower 3 on the structural roof floor 1, and then by adding a waterproof structure 6, the waterproof performance of the roof is guaranteed to avoid the danger to the electrical equipment in the house. In addition, the outlet tower 3 and the embedded parts 5 on the concrete pier 2 are installed by bolts 4, so as to facilitate the installation and construction of the outlet tower 3, reduce the construction difficulty, and improve the construction efficiency.
[0029] As a specific implementation structure, such as Figure 2 As shown, the waterproof structure 6 includes a first waterproof layer 601, a thermal insulation layer 602, a slope layer 603, a leveling layer 604, a second waterproof layer 605, an isolation layer 606, a protective layer 607 and an outer surface layer 608;
[0030] A first waterproof layer 601 is laid on the side wall of the concrete pier 2 and the surface of the structural roof slab 1, and a thermal insulation layer 602 is laid outside the first waterproof layer 601; the thermal insulation layer 602 includes a horizontal thermal insulation layer 6021 located outside the structural roof slab 1 and a vertical thermal insulation layer 6022 located outside the side wall of the concrete pier 2; a slope layer 603 is laid outside the horizontal thermal insulation layer 6021; a leveling layer 604 is laid outside the vertical thermal insulation layer 6022 and the slope layer 603; A second waterproof layer 605 is laid outside the flat layer 604; the second waterproof layer 605 includes a horizontal second waterproof layer 6051 located outside the structural roof slab 1 and a vertical second waterproof layer 6052 located outside the side wall of the concrete pier 2; an isolation layer 606 is laid outside the horizontal second waterproof layer 6051; a protective layer 607 is laid outside the isolation layer 606; an outer surface layer 608 is laid together by the vertical second waterproof layer 6052, the protective layer 607 and the upper outer surface of the concrete pier 2.
[0031] Specifically, the first waterproof layer 601 is laid on the side wall of the concrete pier 2 and the surface of the structural roof slab 1, and specifically includes a horizontal first waterproof layer 6011 laid on the surface of the structural roof slab 1 and a vertical first waterproof layer 6012 laid on the side wall of the concrete pier 2. The first waterproof layer 601 can be one of polyurethane waterproof coating, polymer cement waterproof coating, self-adhesive polymer modified asphalt waterproof membrane, and elastomer modified asphalt waterproof membrane.
[0032] The insulation layer 602 is laid outside the first waterproof layer 601, and specifically includes a horizontal insulation layer 6021 laid outside the horizontal first waterproof layer 6011, and a vertical insulation layer 6022 laid outside the vertical first waterproof layer 6012. The insulation layer 602 can be one of a modular polystyrene foam board, an extruded polystyrene foam board, and a rigid polyurethane foam board. The thickness of the insulation layer 602 is not less than 30 mm.
[0033] The slope layer 603 is used to achieve functions such as roof drainage, so it does not need to be laid on the side wall of the concrete pier 2, but only needs to be laid outside the horizontal insulation layer 6021. The slope layer 603 is 30mm thick LC5.0 lightweight aggregate concrete at the thinnest point, with a slope of 2%.
[0034] The leveling layer 604 needs to be laid on the side wall of the concrete pier 2 and the surface of the structural roof slab 1 at the same time. Therefore, the leveling layer 604 is laid outside the vertical insulation layer 6022 and the slope layer 603. Specifically, the horizontal leveling layer 6041 is laid outside the slope layer 603, and the vertical leveling layer 6042 is laid outside the vertical insulation layer 6022. The leveling layer 604 uses 20mm thick DS M15 mortar.
[0035] The second waterproof layer 605 needs to be laid on the side wall of the concrete pier 2 and the surface of the structural roof slab 1 at the same time to achieve the waterproof function. Therefore, the horizontal second waterproof layer 6051 is laid outside the horizontal leveling layer 6041, and the vertical second waterproof layer 6052 is laid outside the vertical leveling layer 6042. In order to further enhance the waterproof performance, an additional waterproof layer 6053 can also be laid at the intersection of the horizontal second waterproof layer 6051 and the vertical second waterproof layer 6052. The second waterproof layer 605 is a 2mm thick LEAC acrylic polymer cement waterproof coating plus a 1.5mm thick LEAC acrylic polymer cement waterproof coating, wherein the 2mm thick LEAC acrylic polymer cement waterproof coating has a dedicated reinforcement cloth built in, and the 1.5mm thick LEAC acrylic polymer cement waterproof coating has a dedicated reinforcement cloth built in. Therefore, in order to enhance the tensile force of the waterproof coating LEAC waterproof layer, each waterproof layer is added with a carcass reinforcement cloth during construction, referred to as a dedicated reinforcement cloth (≥70g / ㎡).
[0036] The horizontal and vertical parts of the additional waterproof layer 6053 shall not be less than 250mm.
[0037] Furthermore, the second waterproof layer 6052 in the vertical direction is fixedly connected to the concrete pier 2 by means of nails and pressure strips.
[0038] Since the structural roof slab 1 needs to bear the weight of personnel, while the concrete pier 2 does not have this requirement, an isolation layer 606 is only set on the surface of the structural roof slab 1. Specifically, the isolation layer 606 is laid on the surface of the second waterproof layer 6051 in the horizontal direction, and the isolation layer 606 is 20mm thick M15 mortar.
[0039] Similarly, since the structural roof slab 1 needs to bear the load of personnel, while the concrete pier 2 does not have this requirement, a protective layer 607 is only set on the surface of the structural roof slab 1. Specifically, the protective layer 607 is laid on the surface of the isolation layer 606. The protective layer 607 is 40mm thick C20 fine stone concrete, with cold-drawn φ8 bidirectional @150 inside, a partition joint width of 20, and DSM15 mortar (1:3 cement mortar) filled inside, and the vertical and horizontal spacing is not more than 10m.
[0040] The outer surface layer 608 is laid on the side wall of the concrete pier 2 and the surface of the structural roof slab 1. Specifically, the outer surface layer 608 is laid on the second waterproof layer 6052 in the vertical direction, the protective layer 607 and the upper outer surface of the concrete pier 2. The outer surface layer 608 specifically includes: a vertical outer surface layer 6082 laid outside the second waterproof layer 6052 in the vertical direction, a horizontal outer surface layer 6081 laid outside the protective layer 607, and an outer surface layer 6083 laid on the upper outer surface of the concrete pier 2. The outer surface layer 608 can be a LEAC polymer color coating decorative layer. Through the outer surface layer 608, the equipment foundation and the roof are closed to ensure the waterproof quality.
[0041] The utility model provides a plateau high-altitude outgoing line tower structure with a roof waterproof node structure, which has the following advantages:
[0042] 1. The concrete pier is set on the structural roof slab, and the outlet tower is set on the concrete pier to reduce the adverse effect of the outlet tower on the structural roof slab, and then the waterproof structure is installed to ensure the waterproof performance of the roof; in addition, the embedded parts on the outlet tower and the concrete pier are installed by bolts, which facilitates the installation and construction of the outlet tower, reduces the construction difficulty and improves the construction efficiency.
[0043] 2. Laying waterproof structure on the surface of concrete piers and structural roof slabs can prevent water leakage at the intersection of the structural roof slabs and concrete piers, and further improve the waterproof performance of the structural roof slabs.
[0044] 3. The waterproof structure is provided with two waterproof roll layers, namely the first waterproof layer and the second waterproof layer, and the horizontal part and the vertical part of the waterproof roll are protected by the protective layer and the outer surface layer respectively, which can effectively prevent the waterproof roll from being exposed to the external environment, and from hollowing, falling off or being damaged due to wind and sun, and the service life of the waterproof roll is longer.
[0045] 4. The LEAC polymer colored decorative layer is used as the outer surface layer. It has good adhesion and is easy to construct. It is suitable for a variety of heterogeneous base surfaces and has stronger construction performance for detailed nodes such as equipment foundations.
[0046] 5. An insulation layer and an isolation layer are arranged from bottom to top between the horizontal part of the waterproof membrane and the protective layer, which can prevent the external environmental temperature factors such as the hot summer and the cold winter from affecting the waterproof membrane, causing damage to the waterproof membrane and shortening its service life.
[0047] 6. The waterproof layer adopts LEAC acrylic polymer cement waterproof coating, which is a product composed of high molecular acrylic cement modified special emulsion and cement-based powder. It covers three composite technologies, namely, the composite of inorganic materials and organic materials, the composite of chemical network structure and physical network structure, the composite of double network interpenetration and double network integration, and the composite of waterproof coating and waterproof roll material. Its construction is a coating method, and after molding, it is a roll material structure. LEAC acrylic polymer cement waterproof coating has the advantages of full adhesion without water, no overlap, and reliable sealing of various special-shaped surfaces, as well as the advantages of roll materials with high tensile force, good crack resistance and high construction efficiency. The comprehensive physical and mechanical indicators of LEAC acrylic polymer cement waterproof coating are far higher than those of traditional waterproof materials such as SBS and polyurethane; the tensile force of 2.0mm thick can reach 2292N / 50mm, which is 2.8 times that of SBS roll material. Under full adhesion conditions, it can resist a maximum crack of 10mm and a settlement deformation of 12mm. Heat resistance can reach 240℃, no flow for 0.5 hours, and no flow for 4 hours at 100℃. Resistant to UV aging and can be used under long-term exposure to sunlight.
[0048] Therefore, the utility model provides a plateau high altitude outlet tower structure with a roof waterproof node structure, and the outlet tower is set on the concrete pier located on the structural roof floor, which is convenient for the installation and construction of the outlet tower, reduces the construction difficulty, and improves the construction efficiency. At the same time, it reduces the adverse effects of the outlet tower on the structural roof floor, ensures the waterproof performance of the roof, and ensures the stable operation of the power system. The adopted roof waterproof node structure has the advantages of anti-ultraviolet, high temperature resistance, weather resistance, etc., has fewer construction processes, prevents the waterproof roll from hollowing and falling off, and has the advantage of good waterproof performance.
[0049] The above is only a preferred embodiment of the present invention. It should be pointed out that ordinary technicians in this technical field can make several improvements and modifications without departing from the principle of the present invention. These improvements and modifications should also be considered as the protection scope of the present invention.
