Pile space oil continuous reinforced pile group system and construction method thereof

Abstract

The invention provides a pile space oil continuous reinforced pile group system and a construction method thereof. The pile space oil continuous reinforced pile group system comprises two and more foundation piles, a bearing platform, target layer pile space oil and non-target layer pile space oil; and the upper ends of the foundation piles are embedded in the bearing platform by a certain length, and are fixedly connected with the bearing platform, and the rest parts are buried in a pile space oil layer. The system adopts a foundation treatment technology to continuously reinforce the target layer pile space soil; and the reinforced target layer pile space soil forms a continuous high-strength whole in the horizontal direction to supply an excellent manual supporting layer to a pile group. The system can solve the problem of high or ultrahigh bearing force demand of a pile group foundation in a limited range by a lower manufacturing cost, such as large or superlarge foundations as bridges, wind power and petroleum platforms. The invention further provides the construction method of the pile space oil continuous reinforced pile group system.

Description

technical field [0001] The invention relates to the technical field of geotechnical engineering, in particular to a continuous reinforcement pile group system with soil between piles and a construction method thereof. Background technique [0002] As one of the most common types of deep foundations, the role of piles is to transmit various loads borne by the superstructure to the deep part of the foundation soil, so as to meet the bearing capacity requirements of buildings (structures). When the axial force of the upper structural column is relatively large, and the single pile and single column cannot meet the bearing capacity requirements, two or more foundation piles are often designed to jointly bear the load of the upper single column, and the cap is connected by two or more foundation piles and the pile top. Together they form the pile foundation. Caps are transitional components for load transfer between columns and piles. [0003] When the thickness of the Quaterna...

AI Technical Summary

Problems solved by technology

However, although this technology is feasible, there is a bottleneck in the side resistance provided by the soil between the piles, the increase in bearing capacity is limited, and the construction process is complicated and the cost is high
