Embodiment Construction
[0030] Attached to the following Figure 1-2 This application will be described in further detail.
[0031] refer to figure 1 , A building foundation structure provided by the present application includes a foundation pit 1 opened at a designated position, wherein the designated position is an easy settlement area or an uneven settlement area obtained after evaluation by analysis of settlement monitoring data. The size of the excavation of foundation pit 1 is subject to the actual site, generally 5m × 5m is the scope of a foundation pit. A plurality of reinforcement holes 11 are continuously excavated at the bottom of the foundation pit 1 .
[0032] A plurality of reinforcement holes 11 are arranged in an array at the bottom of the foundation pit 1, the depth of each reinforcement hole 11 is preferably 1-1.5m, the diameter of the reinforcement hole 11 is controlled at 30-50cm, and each reinforcement hole 11 is inserted with a Reinforcing cylinder 2. The reinforcement cylind...

The invention relates to the field of house building construction, in particular to a house building foundation structure and a construction method thereof.The house building foundation structure comprises a foundation pit formed in the ground, a plurality of reinforcing holes are excavated in the bottom of the foundation pit, reinforcing cylinders are inserted into the reinforcing holes, the tops of the reinforcing cylinders extend to the position of a pit opening of the foundation pit, and anti-sinking protective cylinders inserted into the ground are arranged on the two sides of the foundation pit; a synchronous steel plate is arranged at the position of a pit opening of the foundation pit, the synchronous steel plate, the top of the reinforcing cylinder and the anti-sinking protective cylinder are welded and fixed, a backfill layer is arranged in the foundation pit, and the construction method comprises the following steps that S1, the foundation pit is excavated; s2, a reinforcing cylinder is inserted into the bottom of the foundation pit; s3, anti-sinking pile casings are inserted into the two sides of the foundation pit, and connecting rods are driven into the side walls of the foundation pit and penetrate through the anti-sinking pile casings; s4, a synchronous steel plate is laid on the top of the foundation pit, and the synchronous steel plate is fixedly welded to the anti-sinking protection cylinder, the reinforcing cylinder and the protection plate; and S5, a bottom reinforcing layer, a middle concrete layer and a top soil layer are sequentially backfilled into the foundation pit, and the advantage of sedimentation prevention is achieved.
Description
technical field [0001] The present application relates to the field of housing construction, in particular to a housing construction foundation structure and a construction method thereof. Background technique [0002] In the field of construction, a building generally includes a house structure and a foundation structure through which the house structure is built on the land. As the foundation of the house structure, the foundation structure is the guarantee of the overall strength of the house building. Therefore, the importance of the foundation structure cannot be overemphasized. [0003] In the related art, generally, the ground is drilled and the bored piles are backfilled for foundation reinforcement. This reinforcement method is relatively common, has high construction efficiency, and can ensure the strength of the foundation and the anti-settling effect to a certain extent. [0004] However, in some areas with uneven settlement, the single foundation construction m...
