Problems solved by technology

[0003] The current soft foundation treatment method is relatively simple in operation, has construction limitations and hidden dangers in the construction and use of later buildings, and the construction period is long, the treatment cost is high, the soft foundation treatment effect and operation efficiency are insufficient, and the treatment completion degree needs to be further improved; therefore, We propose a soft ground treatment method

Embodiment 1

[0036] see figure 1 Shown: the present invention is a kind of soft ground treatment method, comprises the following steps:

[0037] Step 1: Smooth the surface of the soft base area 4. The operation needs to remove large pieces of soil and foreign matter, so that it will not cause the use of the operating cylinders to be inclined;

[0038] Step 2: first place the soil loosening cylinder 1 and fix it, including fixing the bottom end of the soil loosening cylinder 1 to the soil layer and the side end to the soil layer;

[0039] Step 3: Use the drill bit 10 to drill down, use the stirring rod 11 to break up the drilled soft soil during the drilling process, drill the drill bit 10 to the depth of the foundation construction during operation, turn on the drive motor 8, and drive the stirring rod 11 to run , stir and disperse the drilled soft soil;

[0040] Step 4: Turn on the heating bar 13 to heat the dispersed soft soil and evaporate the water vapor on the surface;

[0041] Ste...

Embodiment 2

[0047] Such as Figure 2-5 As shown: in this scheme, the soil loosening cylinder 1 is first installed on the operating surface of the soft foundation area 4, and the drill bit 10 is installed inside the soil loosening cylinder 1, and the drill bit 10 is used to drill down into the soft soil layer, and the telescopic shaft 12 is used to drill down to the depth At the same time, install the drive motor 8 on the upper end of the loose soil cylinder 1, fix it with the fixing piece 9, turn on the drive motor 8, drive the stirring rod 11 through the drive shaft to stir the soft soil, and drill the soft soil. Loosen, open the heating bar 13 connected to the inner side of the loose soil cylinder 1, and the soft soil scattered by the heating bar 13 is heated to evaporate the moisture on the surface of the soft soil to form water vapor evaporation;

[0048] After the completion, carry out the secondary operation, take out the loose soil cylinder 1 and place the vacuum cylinder 2, instal...

Abstract

The invention discloses a soft foundation treatment method, and relates to the technical field of soft foundation treatment. The soft foundation treatment method comprises the following steps that S1, surface leveling is conducted on the superficial surface of a soft foundation; S2, a soil loosening cylinder is placed and fixed; S3, a drill bit is used for downward probing, and a stirring rod is used for scattering drilled soft soil; S4, the scattered soft soil is heated, and water vapor on the surface is evaporated; S5, a vacuumizing barrel is placed, and vacuumizing operation is conducted through a vacuumizing pipe; S6, a pressing and filling cylinder is placed, and the surface of the soft foundation is compacted through a compacting plate; S7, after the independent operation areas of all the operation cylinders are completed in sequence, position movement continues to be conducted in the soft foundation operation area; S8, a sealing plate is installed; and S9, the soft foundation treatment method is completed. According to the soft foundation treatment method, the three stages of operation cylinders are used for conducting surface treatment on the soft foundation, the soft soil hardening operation is completed, and the soft foundation treatment effect and treatment efficiency are improved.

Description

technical field [0001] The invention relates to the technical field of soft ground treatment, in particular to a soft ground treatment method. Background technique [0002] Soft foundation treatment is also called soft foundation treatment, soft soil foundation reinforcement treatment, if the foundation is not strong enough before construction, in order to prevent accidents such as building instability caused by foundation sinking and cracking after construction, it is necessary to treat the soft foundation to make it settle It is the process of becoming strong enough to improve the consolidation degree and stability of the soft foundation to meet the design requirements. Soft foundation treatment is widely used in my country's coastal areas and inland areas, especially in some areas of reclamation. Generally, surveys are required before construction. Then carry out soft foundation treatment, otherwise there will be great risks and future troubles; [0003] The current soft f...
