Embodiment Construction

[0035](1) Carry out detailed investigation and analysis first, grasp the load standards and design requirements of the proposed site and roads and other above-ground facilities, and clarify the grade standard of the proposed site treatment and reinforcement (including the indicators required by the design). At the same time, be familiar with the engineering geological survey data of the proposed site and the technical conditions for the formation of the dredged sand layer, recognize the characteristics of the soil properties, grasp the treatment depth and treatment range, and formulate appropriate control standards for intensity.

[0036] (2) Reasonably design the proposed construction site and apply the construction process of this construction method, and carry out specific analysis of the specific site, so that the organic matching process can be matched to the number, which is more realistic.

[0037] (3) Design an experimental construction scheme applying this construction...

Abstract

The present invention relates to a forced drainage combined type dynamic consolidation method. It is characterized by that said invention adopts a mutually-matched and flexible combination of two reinforcement methods of network light-type well-point forced drainage method and low-energy dynamic consolidation method to effectively apply prestress to soft ground soil skeleton, namely, repeatedly apply dynamic stress and static stress to soil skeleton so as to accelerate the drainage consolidation of soil mass. The invented method is applicable to reinforcement of soft foundation.

Description

1. Technical field [0001] The invention belongs to the category of soft ground reinforcement treatment methods, and is particularly suitable for treating new-born land soft foundations dredged and filled with silt and fine sand layers interspersed with saturated soft clay, and even new-born land soft grounds dredged and filled with riprap. It is a fast, cheap and efficient new construction method for soft ground treatment. 2. Background technology [0002] In recent years, most of the proposed sites for the construction of deep-water port container terminal yards and roads in the world have used the new land soft foundation formed by riprapping rocks, silting and sand blowing, and land reclamation and reclamation. Therefore, the soft foundation must be seriously reinforced to meet the load requirements of the construction of heavy port wharves. The traditional surcharge preloading method and overload preloading method and other drainage consolidation methods make the port c...
