Description

Technical Field

[0001] This utility model relates to the field of building construction technology, specifically to a building construction foundation pit support structure. Background Technology

[0002] In the construction process, foundation pit support is a crucial link in ensuring construction safety and project quality. With the continuous development of urban construction, the scale and height of buildings are increasing, and the requirements for foundation pit support structures are also becoming more stringent.

[0003] Traditional foundation pit support structures suffer from insufficient stability. When faced with complex geological conditions and large foundation pit depths, traditional support structures are prone to deformation and collapse, failing to effectively ensure construction safety. For example, in soft soil geology, the bearing capacity of foundation pit support is low, and the support structure cannot provide sufficient anchoring force, leading to excessive soil deformation or even collapse. Utility Model Content

[0004] The technical problem to be solved by this utility model is to provide a support structure for building construction pits, addressing the shortcomings mentioned in the background art.

[0005] To solve the above-mentioned technical problems, the technical solution provided by this utility model is: a building construction pit support structure, including a main support column structure, wherein the main support column structure includes a front support structure, a middle support structure and a rear support structure.

[0006] The front support structure includes multiple first concrete piles, the middle support structure is a middle main concrete slab structure, and the rear support structure includes multiple second concrete piles.

[0007] The front support structure, middle support structure and rear support structure are all provided with a concrete cap beam structure at the top, and the multiple first concrete piles are provided with multiple concrete waist beam structures from top to bottom.

[0008] Furthermore, an auxiliary concrete slab structure is cast between each pair of the concrete cap beam structure and the multiple concrete waist beam structures.

[0009] Furthermore, the concrete cap beam structure is provided with multiple reinforced concrete column structures that penetrate the concrete waist beam structure and the main concrete slab structure.

[0010] Furthermore, the outer sides of the multiple second concrete piles are spirally arranged.

[0011] Furthermore, the distance between the concrete waist beam structure and the concrete cap beam structure mentioned above is greater than 1.5m and less than 2.5m, and the distance between any two of the concrete waist beam structures mentioned above is greater than 1m and less than 1.5m.

[0012] The advantages of this utility model for constructing a foundation pit support structure compared to existing technologies are as follows: This utility model, through a front support structure, a middle support structure, and a rear support structure, combined with a concrete cap beam structure and multiple concrete waist beam structures, can ensure the overall stability of the foundation pit support structure.

[0017] The present invention will now be described in further detail with reference to the accompanying drawings.

[0018] Combined with appendix Figure 1-3A foundation pit support structure for building construction includes a main support column structure. The main support column structure comprises a front support structure, a middle support structure, and a rear support structure. The front support structure includes multiple first concrete piles 1. The middle support structure is a central main concrete slab structure 3. The rear support structure includes multiple second concrete piles 2. A concrete cap beam structure 4 is provided at the top of the front, middle, and rear support structures. Multiple concrete waist beam structures 5 are provided from top to bottom for the multiple first concrete piles 1. The main structure consists of the front, middle, and rear support structures. In actual operation, the first concrete piles 1 and second concrete piles 2 are excavated in a uniformly distributed manner. After the excavation of the pouring hole is completed, concrete is poured to form the structure. After the first concrete pile 1 and the second concrete pile 2 are poured, the middle trench of the main concrete slab structure 3 is excavated between the first concrete pile 1 and the second concrete pile 2. After the excavation is completed, concrete is poured again to form the front support structure, the middle support structure and the rear support structure. After the pouring is completed, the concrete cap beam structure 4 is poured together on the top of the front support structure, the middle support structure and the rear support structure. After the concrete cap beam structure 4 is formed, the foundation pit is excavated. After the foundation pit is excavated to the position of the highest concrete cap beam structure 4, the second concrete pile 2 is poured to form the concrete cap beam structure 4. Then the concrete cap beam structure 4 is excavated and poured in sequence until the appropriate depth is reached.

[0019] A secondary concrete slab structure 7 is poured between each pair of the concrete cap beam structure 4 and the multiple concrete waist beam structures 5. That is, the main support and waterproof concrete are set between each pair of the concrete cap beam structure 4 and the multiple concrete waist beam structures 5 to ensure the long-term use of the foundation pit as a whole.

[0020] The concrete cap beam structure 4 is provided with multiple reinforced concrete column structures 6 that penetrate the concrete waist beam structure 5 and the main concrete slab structure 3, as shown in the figure. The reinforced concrete column structure 6 is generally set between two first concrete piles 1 or two second concrete piles 2, and the angle with the horizontal is generally less than 45° and greater than 30° to ensure the overall strength of the support structure. Generally, after pouring the concrete cap beam structure 4, holes are drilled in the concrete cap beam structure 4 to penetrate the main concrete slab structure 3, and then steel bars are rolled in the holes before pouring, to ensure the overall strength of the operation.

[0021] The outer side of the multiple second concrete piles 2 is spirally arranged. During actual pouring, the second concrete piles 2 can be drilled in an outer spiral manner to form irregular concrete piles, which can prevent sinking when the soil is relatively soft.

[0022] The concrete waist beam structure 5 at the top is set with a distance greater than 1.5m and less than 2.5m from the concrete crown beam structure 4. The distance between any two of the concrete waist beam structures 5 is greater than 1m and less than 1.5m. By setting the spacing, the overall strength and stability of the support structure can be further guaranteed.

[0023] The present invention and its embodiments have been described above. This description is not restrictive, and the accompanying drawings are only one embodiment of the present invention; the actual structure is not limited thereto. In conclusion, if those skilled in the art are inspired by this description and design similar structures and embodiments without departing from the inventive spirit of the present invention, such designs should fall within the protection scope of the present invention.
