Embodiment 1

[0060] The soft soil foundation of a sea reclamation project is treated, the soft soil layer is 20-25m thick, and the surface layer is 3-5m thick dredging fill. The design parameters of the soft soil foundation are shown in the table below.

[0061]

[0062] A method of applying aerosol to disturb the soft soil foundation, comprising the following steps:

[0063] (1) Vertical drainage channels: the ground treatment drainage channels are designed in accordance with the "Technical Specifications for Building Foundation Treatment", and the measurement and setting out are carried out according to the design, the soft soil foundation treatment area is determined, the site is leveled, and multiple vertical drainage bodies Drilling to the design depth, the top of the drainage body 1 exposes the surface layer of the soft soil foundation;

[0064] The drainage body adopts a plastic drainage board, the depth of the drainage body driven into the soft ground is 18m, and the specificati...

Embodiment 2

[0078] The treatment method to the soft ground is the same as that of Example 1, except that in step (1), the drainage body is a bagged sand well with a diameter of d w is 100mm, the drainage body is arranged in a square, and the effective drainage diameter of the drainage body is d e is 1.356m, and L is 1.2m. The permeability coefficient of the soft soil foundation treated by the method of the present invention increases by two orders of magnitude, the void ratio decreases, and the shear strength of the cross plate significantly increases. The changes of each parameter over time are basically the same as in Example 1.

[0079] After the entire area is sprayed, take out the casing, and in about 3-4 months, all indicators of the soft soil foundation meet the treatment requirements.

Embodiment 3

[0081] The treatment method for the soft soil foundation is the same as that of Example 1, except that in step (3), after the cushion layer and drainage ditches are set, the pile carrier is laid on the cushion layer, and then the punching process is used to pass through the pile carrier 1. The cushion layer is provided with a punching channel in the soft soil foundation to be treated; the depth of the punching channel is guaranteed to pass through the backfill and the cushion layer, and go deep into the soft soil foundation by 50cm, with a diameter of 10cm.

[0082] The heap carrier is preloaded, and the material is pond slag. The height of the heap is 3m, and the heap is divided into 2 times. The first layer is laid with 1.5m. %, and the degree of compaction is required to be >90%, and the total height of the backfill is calculated according to the bearing capacity requirements of the foundation treatment.

[0083] The permeability coefficient of the soft soil foundation trea...

Abstract

The invention discloses a method for using aerosol to disturb the soft soil foundation. After setting the drainage body, the cushion layer, the drainage ditch, the casing or the punching channel, the spray pipe is passed through the casing or the punching channel, and the The liquid or solid aerosol raw material in the aerosol generator is atomized to form an aerosol, which is injected into the soil with high pressure; On the other hand, a horizontal cutting surface with a small thickness is formed in the soil, and horizontal drainage channels are added to shorten the drainage distance and achieve the effect of rapid drainage. The method of the invention can accelerate the consolidation speed of the soil body, deepen the treatment depth of the soil body, and reduce the long-term creep of the soil body.

Description

technical field [0001] The invention relates to a foundation treatment method, which is suitable for treating soft soil foundations, in particular to a method for disturbing soft soil foundations by using aerosol, and belongs to the technical field of civil engineering. Background technique [0002] Soft soil is mostly distributed in the southeast coast of my country, and according to geological origin, soft soil is divided into: coastal environment deposition. Sea and land excessive environmental deposition (delta deposition), river environmental deposition, lake environmental deposition and swamp environmental deposition. With the production and development of human society and the continuous increase of population density, more and more soft soil will be used as the foundation of buildings. When soft soil is used as foundation or other purposes, it needs to be reinforced. Due to the properties of high water content, high void ratio and high flow plasticity of soft soil, ...
