Description

Technical Field

[0001] The utility model belongs to the technical field of construction engineering, and more specifically, particularly relates to a combined mesh foundation structure for soft soil. Background Art

[0002] Soft soil refers to fine-grained soil with high natural water content, large porosity, high compressibility and low shear strength deposited in coastal areas, lakes, valleys and riverbanks. It has the characteristics of high natural water content, large natural porosity, high compressibility, low shear strength, small consolidation coefficient, long consolidation time, high sensitivity, high disturbance, poor permeability, complex layered distribution of soil layers, and large differences in physical and mechanical properties between layers. Due to the low strength and large amount of hidden settlement of soft soil, it often brings great harm to road projects. If it is not handled properly, it will have a great impact on the construction and use of highways. In order to build structures on soft soil foundations, it is necessary to adopt a reinforced structure of the foundation to prevent settlement after the building is built.

[0003] The prior art mostly uses the method of building foundation piles to strengthen the soft soil layer. This solution is simple to implement and has low construction cost, but its structure still has defects. Since the upper part of the foundation pile is still soft soil, it is easy to tilt, which leads to a decrease in the overall foundation stability.

[0004] Therefore, in view of this, the existing structure and deficiencies are studied and improved, and a combined mesh foundation structure for soft soil is provided, in order to achieve a more practical purpose. Utility Model Content

[0005] In order to solve the above technical problems, the utility model provides a combined mesh foundation structure for soft soil, so as to solve the problem that the soft soil foundation in the prior art is easy to tilt because the upper part of the foundation pile provides lateral force with soft soil.

[0006] The purpose and effect of the combined mesh foundation structure for soft soil of the utility model are achieved by the following specific technical means:

[0007] A combined mesh foundation structure for soft soil, comprising:

[0008] An array of multiple foundation piles is arranged in a soft soil layer, a gravel paving layer is paved on the upper periphery of the foundation piles, a reinforced concrete frame is arranged on the upper part of the foundation piles, and a fence is wrapped around the periphery of the foundation piles.

[0009] Furthermore, the gravel paving layer is paved with granite crushed stones.

[0010] Furthermore, the enclosure is built with bricks, and the outer surface of the enclosure is covered with waterproof material.

[0011] Furthermore, the height of the enclosure is H, H≥2m.

[0012] Furthermore, the waterproof material adopts polymer modified asphalt waterproof membrane or synthetic polymer waterproof membrane.

[0013] Furthermore, it also includes a drainage mechanism, which includes an annular tube arranged at the bottom of the foundation pile, a drainage pipe with one end connected to the annular tube, and a water pump connected to the other end of the drainage pipe; a plurality of water filtering holes are arranged on the upper part of the annular tube.

[0014] Compared with the prior art, the utility model has the following beneficial effects:

[0015] 1. The utility model increases the anti-tilt ability of the foundation pile by laying a gravel paving layer on the periphery of the foundation pile and wrapping a fence around the gravel paving layer, and is easy to construct and has high applicability.

[0016] 2. At the same time, the utility model is provided with a drainage mechanism, which collects accumulated water by arranging an annular pipe at the bottom of the foundation pile, and the drainage pipe extends into the bottom of the annular pipe, and then the water is pumped out by a water pump, so that the moisture content of the soft soil layer is reduced, thereby increasing the anti-subsidence ability of the soft soil layer.
