Multi-point stress vibrating-punching combined compacting method

Abstract

This invention applies a combined method of vibration and striking rolling and squeezing of multi-point forced vibration to compact loose sand ground base, among which, the combined squeezing method applies a pre-force action to the loose sand bone, namely, a vibration and striking force is applied to urge the saturated loose sand earth to generate a pre-deformation and pre-sink to let the processed basic earth meet the deforming requirement of the project in the usage stage. To the filled sand ground base for a strengthening port, its pre-force standard is controlled in the sphere of 0.85~0.65 and the vibration-squeezed compact work is finished within 1-7days after the vibration and striking.

Description

1. Technical field [0001] The invention belongs to the category of soft ground reinforcement treatment methods, and is particularly suitable for the treatment of loose sandy soil foundations, even saturated silt and fine sand foundations, in large-area new dredging and reclamation land areas on the banks of ports. It is a fast and efficient dredging-fill loose-sand soft foundation treatment method without filler. 2. Background technology [0002] There are hundreds or even thousands of ground treatment and reinforcement methods at home and abroad. For the treatment of loose sandy soil foundations in large areas of new dredging and land reclamation on the banks of ports, the traditional treatment methods mostly use surcharge preloading and overloading preloading methods. , but the processing cycle is too long and cannot meet the requirements of rapid port construction in recent years. Common construction methods such as vibrating and rolling methods are available, but the ef...

Problems solved by technology

CN03115076.4 relates to a non-filler vibrating process, but it is limited to a specific process, and cannot fundamentally apply the force-giving principle to the foundation soil to solve the problem, and there is no complete theoretical system support for the treatment design and construction. Treatment effects and benefits are subject to high restrictions
