Embodiment Construction

[0015] In order to make the technical problems, technical solutions and advantages to be solved by the present invention clearer, the following will describe in detail with reference to the drawings and specific embodiments.

[0016] The present invention provides a permeable foam concrete pile composite foundation aiming at the problems of large pile self-weight and poor water permeability in the existing various composite foundations.

[0017] like figure 1 , figure 2 and image 3 As shown, the permeable foam concrete pile composite foundation consists of a pile body 1, a pile cap 2 and a mattress layer 3, the pile cap 2 is arranged on the top of the pile body 1, and the mattress layer 3 is arranged above the pile cap 2.

[0018] like Figure 4 As shown, a road project in a certain area carries out reinforcement treatment to weak ground, adopts the permeable foam concrete pile composite ground provided by the present invention. In order to make the subgrade meet the bea...

Abstract

The invention provides a permeable foam concrete pile composite foundation, which belongs to the technical field of civil engineering. The foundation includes a pile body, a pile cap and a cushion layer, the pile cap is located on the top of the pile body, and the cushion layer is located above the pile cap. The material of the pile body is permeable foam concrete. The composite foundation of the permeable foam concrete pile reduces the self-weight of the pile body, enhances the water-permeable capacity of the pile body, and forms a longitudinal drainage channel, thereby reducing the settlement caused by the self-weight. Accelerate the consolidation of the foundation soil, effectively improve the bearing capacity of the composite foundation, control the settlement of the foundation after construction, and shorten the construction period. At the same time, due to the characteristics of light weight and water permeability, the composite foundation of the present invention can achieve the same treatment effect with smaller-sized piles, reduce construction and material consumption, effectively control engineering costs, and obtain better economic benefits.

Description

technical field [0001] The invention relates to the technical field of civil engineering, in particular to a permeable foam concrete pile composite foundation, which is suitable for reinforcing weak foundations. Background technique [0002] At present, in the construction of road engineering, the form of composite foundation is often used to strengthen the soft foundation. Among them, the pile foundation can transfer load to the deep soil layer and is widely used. At present, the piles commonly used in composite foundations have large pile materials and poor water permeability, which is not conducive to the full bearing capacity of the foundation soil. The pile itself is prone to large settlement and the foundation is consolidated slowly. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a permeable foam concrete pile composite foundation, so as to overcome the shortcomings of large pile deadweight and poor water ...
