Description

Technical Field

[0001] This utility model relates to the field of photovoltaic technology, and in particular to photovoltaic support for landfills. Background Technology

[0002] Currently, the common foundation types for ground-mounted photovoltaic (PV) systems in China include: ① independent concrete foundations; ② concrete strip foundations; ③ steel helical pile foundations; ④ micro-hole cast-in-place steel pipe pile foundations; ⑤ cast-in-place reinforced concrete pile foundations; and ⑥ precast concrete pipe pile foundations. Conventional slope PV systems use pile foundations to resist horizontal and pull-out forces. However, for landfill applications, pile foundations would damage the existing site cladding layer, and conventional independent concrete foundations cannot meet the load-bearing capacity and anti-slip requirements of PV systems.

[0030] Steel column 4, its bottom fixed to pier 3; and,

[0031] Photovoltaic module 5 is fixed to the top of steel column 4.

[0032] The photovoltaic support foundation applied to the landfill in this embodiment mainly consists of strip foundation 1, piers 3, and tie beams 2. The cast-in-place strip foundation 1 is used to increase the anti-slip coefficient μ between the bottom of the foundation and the soil, so as to meet the anti-slip requirements of the specifications without damaging the impermeable membrane at the bottom of the soil layer. The tie beams 2 are used to connect the strip foundation 1 to form a mesh structure, which increases the rigidity of the overall structure, reduces the impact of uneven settlement of the site, and ensures stability and safety.

[0034] In one embodiment, please refer to Figure 2 The tie beam 2 includes two parallel tie rods 21, and at least one support rod 22 connected to the tie rod 21 is provided between the tie rods 21.

[0035] In this embodiment, the adjacent strip foundations 1 are effectively connected by tie rods 21, and the multiple evenly arranged strip foundations 1 form a mesh structure, which increases the rigidity of the overall support structure, reduces the impact of uneven settlement of the site, and ensures stability and safety.

[0036] In one embodiment, please refer to Figure 2Both ends of the tie rod 21 extend into the interior of the strip base 1, and both ends of the tie rod 21 are provided with extensions 23 that form an angle with the main body.

[0037] Specifically, during construction, the extension 23 is integrally cast with the tie rod 21 by binding with steel bars.

[0046] In one embodiment, please refer to Figure 6 A diagonal brace 10 is provided between adjacent steel columns 4. The two ends of the diagonal brace 10 are detachably connected to the steel columns 4, and the diagonal brace 10 is in contact with the bottom of the photovoltaic module 5.

[0047] In this embodiment, the installation of the inclined tie beam 10 can further improve the overall structural strength of the photovoltaic support 5 and provide stable support for the photovoltaic module 5, thus ensuring overall stability.

[0048] In one embodiment, the steel column 4 has a slot, and the end of the cable beam 10 has a protrusion that matches the slot. The protrusion is fixed by a fastening bolt.

[0049] In this embodiment, the cable tie beam 10 and the steel column 4 are detachably connected, which improves the convenience of installation and transportation. Specifically, during installation, the protrusion at the end of the cable tie beam 10 is aligned with the slot on the steel column 4 and then fixed with fastening bolts.
