Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of greenhouse foundation systems, specifically a greenhouse foundation system. Background Technology
[0002] Existing agricultural greenhouses cannot use concrete for their foundations because concrete would pollute the soil. In permafrost regions, the cyclical expansion and contraction of the soil during winter and spring thaw pose a serious threat to the stability of greenhouse foundations. Traditional foundation treatment methods often fail to effectively address the effects of permafrost, leading to structural damage and impacting agricultural production. Utility Model Content
[0003] To address the aforementioned problems, i.e., the issues raised in the background art, this utility model proposes a greenhouse foundation system, comprising a compacted soil layer, a foundation frame, and pile foundations. The shape of the compacted soil layer is consistent with the projected shape of the greenhouse ground. The pile foundations penetrate the compacted soil layer and extend into the soil stabilization layer. The foundation frame is positioned above the compacted soil layer and is connected to the pile foundations. The foundation frame is configured as at least one set, and each set of the foundation frame is configured to have a shape consistent with the projected shape of the greenhouse ground. At least one set of vertically placed frost-resistant boards is embedded inside the compacted soil layer, and each set of frost-resistant boards is arranged in close contact to form a shape consistent with the projected shape of the greenhouse ground.
[0004] A further feature of this invention is that a rammed earth slope is provided above the rammed earth layer, the rammed earth slope is located in the shaded area of the greenhouse, and the rammed earth slope is located outside the outermost group of the foundation frame.
[0005] A further feature of this invention is that adjacent sets of frost-proof plates are staggered, and the frost-proof plates are located inside the outermost set of foundation frames.
[0006] A further feature of this invention is that the pile foundation is made of angle steel, and the angle steel is fixedly connected to the foundation frame.
[0007] A further feature of this invention is that the pile foundation uses a ground stake, which is fixedly connected to the foundation frame.
[0008] A further feature of this invention is that the outer wall of the grounding rod is provided with barbs or threads.
[0009] The beneficial technical effects of this utility model are as follows: the frost-proof board effectively isolates the frozen soil from the impact of the frozen soil on the soil inside the greenhouse, ensuring the stability of the foundation; the mutual compression stress between the compacted soil layer and the frost-proof board enhances the overall strength of the foundation; the pile foundation penetrates deep into the stable layer, providing strong bearing capacity and preventing foundation settlement; the compacted soil slope increases the stability of the wall surface, prevents cold air intrusion, and improves the heat preservation performance of the greenhouse.

[0014] Preferred embodiments of the present invention will now be described with reference to the accompanying drawings. Those skilled in the art should understand that these embodiments are merely illustrative of the technical principles of the present invention and are not intended to limit the scope of protection of the present invention.
[0015] This invention proposes a greenhouse foundation system. A foundation system with an area larger than the ground projection of the greenhouse to be erected is installed. First, a trench is dug in the ground. Then, frost-resistant boards 3 are vertically placed and filled in the trench. Excess soil is then filled into the gaps, and the ground is compacted to form a compacted soil layer. This compacted soil layer 1 and the frost-resistant boards 3 create mutual compressive stress. Next, piles 5 are inserted, extending into the stable layer below the frozen soil layer. Finally, the foundation frame 4 is connected on the ground to form the shape of the greenhouse's ground projection. For the connection, the connection method can be bolted or welded. Then, the pile foundation 5 is connected and fixed to the foundation frame 4. Then, the greenhouse frame is erected on top of the foundation frame. The number of foundation frames 4 needs to be determined according to the number of layers required for the greenhouse. For example, for a double-layer greenhouse, two sets of foundation frames 4 are required. After the greenhouse is erected, a compacted soil slope 2 is laid on the shaded side of the greenhouse. The compacted soil slope 2 fits closely to the erected greenhouse wall to increase the stability of the wall and prevent cold air from entering the greenhouse through the ground gaps in winter.
[0016] The foundation frame 4 is generally made of angle steel or square steel. When the pile foundation 5 is made of angle steel, the angle steel can be welded to the foundation frame, or holes can be drilled in both for bolt connection. When the pile foundation 5 is made of ground stake, holes can be drilled in the bottom surface of the foundation frame 4, and then connected and fixed by connectors or welding. The ground stake can be directly welded to the side of the foundation frame 4.
[0017] The number of piles 5 needs to be determined according to the properties of the ground soil. If the ground soil is loose and prone to cracking, the density of piles 5 needs to be increased to improve the firmness of the compacted soil layer 1. If the ground soil is dense and sticky, the density of piles 5 can be reduced accordingly.
[0018] The purpose of installing the frost-proof board 3 is first to isolate the frozen soil from the impact of the frozen soil on the soil inside the greenhouse. Generally, XPS or EPS insulation boards are selected. Through the mutual compression between the compacted soil layer 1 and the frost-proof board 3, the frost-proof board 3 has a certain elastic deformation ability. In the event of frost heave, the frost-proof board 3 can be compressed to prevent the foundation from heaving and damaging the greenhouse. It can also expand after the frozen soil melts and water is lost, ensuring the density of the compacted soil layer. At the same time, it works in conjunction with the pile foundation 5 inserted into the stabilizing layer to ensure the stability of the greenhouse foundation.
[0019] Although the present invention has been described with reference to preferred embodiments, various modifications can be made to it and components can be replaced with equivalents without departing from the scope of the present invention. In particular, the technical features mentioned in the various embodiments can be combined in any manner as long as there is no structural conflict.
