Abstract
Description
Technical Field
[0001] This utility model relates to the field of agricultural greenhouse technology, specifically to a greenhouse foundation designed to prevent ground subsidence. Background Technology
[0002] Currently, greenhouse buildings commonly employ a structural form combining a centrally located independent foundation with surrounding strip foundations. This design can meet stability requirements under normal geological conditions. However, when encountering situations with insufficient foundation bearing capacity or uneven soil texture, the foundation structure is prone to uneven settlement. This settlement can lead to stress concentration, component deformation, and even cracking in the upper greenhouse structure, seriously affecting the building's safety and service life.
[0003] In existing technologies, isolated foundations require high local bearing capacity and are prone to differential settlement under soft soil conditions; while strip foundations can distribute loads, they are less adaptable to overall soil deformation. Traditional solutions often involve soil reinforcement or increasing the foundation area, but these methods suffer from high construction costs, long construction periods, and damage to the topsoil. Especially in seasonally frozen or soft soil areas, conventional foundation structures struggle to effectively control uneven settlement.
[0004] There is currently no effective solution to the above problems. Utility Model Content
[0005] In view of the above-mentioned technical problems in related technologies, this utility model proposes a greenhouse foundation that prevents ground subsidence, which can overcome the above-mentioned shortcomings of the prior art.
[0006] To achieve the above-mentioned technical objectives, the technical solution of this utility model is implemented as follows:
[0007] A greenhouse foundation designed to prevent ground subsidence includes several horizontally and vertically arranged pile foundations on a greenhouse foundation prone to settlement. The horizontally arranged pile foundations are connected by corresponding horizontal ring beams, and the vertically arranged pile foundations are connected by corresponding vertical ring beams. The vertical intersection of the horizontal and vertical ring beams is located in a localized area of high weight or a localized area of severe ground settlement. Corresponding local pile foundations are provided in four directions at each vertical intersection of the horizontal and vertical ring beams.
[0008] Furthermore, both the pile foundation and the partial pile foundation include independent column piers located below zero level. The lower part of each independent column pier is provided with cast-in-place steel pipe concrete piles, and the corresponding transverse ring beam or the vertical ring beam penetrates the corresponding pile foundation or the partial pile foundation.
[0009] Furthermore, both the transverse ring beam and the vertical ring beam are provided with a crushed stone pad layer at their lower parts.
[0010] Furthermore, the top surfaces of the transverse ring beam, the vertical ring beam, the pile foundation, and the partial pile foundation are flush.
[0011] Furthermore, the vertical intersection is at the same distance from the local pile foundation.
[0012] Furthermore, the distance between the vertical intersection and the local pile foundation is 1.5m.
[0013] The beneficial effects of this utility model are as follows: This utility model improves the bearing capacity by setting pile foundations on easily settled foundations, densifies the pile foundation arrangement in local load-bearing areas, and connects the pile foundations into an integral force-bearing system through ring beams. It effectively solves the technical problem that traditional greenhouse foundations are prone to uneven settlement under soft foundation conditions, and has great practical value.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model are within the protection scope of the present utility model.
[0022] like Figure 1-5 As shown in the embodiment of this utility model, a greenhouse foundation for preventing ground subsidence includes several horizontally and vertically arranged pile foundations 1 on the easily subsiding foundation of the greenhouse. The horizontally arranged pile foundations 1 are connected by corresponding horizontal ring beams 2, and the vertically arranged pile foundations 1 are connected by corresponding vertical ring beams 3. The vertical intersection of the horizontal ring beams 2 and the vertical ring beams 3 is located in a local area with heavy weight or a local area with severe ground subsidence. Corresponding local pile foundations 4 are provided in four directions at the vertical intersection of the horizontal ring beams 2 and the vertical ring beams 3.
[0023] In the embodiment, both the pile foundation 1 and the partial pile foundation 4 include independent column piers 5 located below the zero level. The lower part of the independent column pier 5 is provided with cast-in-place steel pipe concrete piles 6, and the corresponding transverse ring beam 2 or the vertical ring beam 3 penetrates the corresponding pile foundation 1 or the partial pile foundation 4.
[0024] In this embodiment, both the transverse ring beam 2 and the vertical ring beam 3 are provided with a crushed stone pad layer 7 at their lower parts.
[0025] In this embodiment, the top surfaces of the transverse ring beam 2, the vertical ring beam 3, the pile foundation 1, and the partial pile foundation 4 are flush.
[0026] In this embodiment, the vertical intersection is at the same distance from the local pile foundation 4.
[0027] In this embodiment, the distance between the vertical intersection and the local pile foundation 4 is 1.5m.
[0028] The column 8 is connected to the pile foundation 1 or a partial pile foundation 4 via the main column base plate 501 and anchor bolts 502. The transverse ring beam 2 and the vertical ring beam 3 have the same structure.
[0029] To facilitate understanding of the above-mentioned technical solutions of this utility model, the following detailed description of the above-mentioned technical solutions of this utility model is provided through specific usage methods.
[0030] In practical use, according to the greenhouse foundation for preventing ground settlement described in this utility model, it is required that a geological survey be carried out before the greenhouse is designed and constructed. For foundations prone to settlement, pile foundations are used to increase the bearing capacity. In areas with heavy local weight, pile foundation points are added, and the pile foundation points are connected by ring beams to form an overall load-bearing structure, which effectively solves the problem of foundation settlement.
[0031] At each independent column pier, a ∅325mm*9m steel pipe concrete cast-in-place pile is designed to extend 9 meters underground. Below ground level, a concrete pier with a length*width*height of 600*600*600 is designed, and embedded parts are embedded in the concrete pier. The column piers are connected by a 400*240 reinforced concrete ring beam. A crushed stone cushion layer with a width of 500 and a thickness of 200 is designed under the ring beam.
[0032] In areas of severe localized foundation settlement, an identical pile foundation is installed 1.5 meters away in four directions along the axis of each independent column pier. The independent column piers are connected by ring beams along the axis to form a unified load-bearing structure, which greatly eliminates uneven settlement.
[0033] In summary, by utilizing the above-mentioned technical solution of this utility model, the bearing capacity is improved by setting pile foundations on easily settled foundations, the pile foundations are densely arranged in local load-bearing areas, and the pile foundations are connected into an integral load-bearing system by ring beams. This effectively solves the technical problem that traditional greenhouse foundations are prone to uneven settlement under soft foundation conditions, and has great practical value.
[0034] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
