Problems solved by technology

The vibration wave generated by the vibrator propagates from one point to the surrounding, and the vibration intensity attenuates rapidly during the propagation process, so its effective reinforcement range is limited

Embodiment Construction

[0044] see figure 1 , figure 2 , image 3 , Figure 4 Shown:

[0045] An immersed tube excitation compaction method, which generates vibration waves in the soil layer through the tube body sunk into the foundation:

[0046] As the excitation source in the soil layer, the pipe body generates vibration waves in the soil layer through the vibration of the pipe body;

[0047] The forms of vibration waves include longitudinal waves, transverse waves and surface waves.

[0048] It strengthens and compacts the soil by means of vibration waves:

[0049] During the transmission process of the vibration wave, it will squeeze and shear the foundation soil, rearrange the soil particles, discharge the water and gas in the soil, and make the soil consolidate and compact, so as to achieve the purpose of strengthening the foundation soil ;

[0050] Part of the vibration wave propagates to the outside of the pipe body, and the soil within a certain range outside the pipe body is reinfo...

Abstract

Provided is a tube sinking and excitation compacting method. By means of the method, foundation soil which is loose and needs to be reinforced can be rapidly and effectively reinforced. The method includes the following steps of firstly, measuring and placing point positions; secondly, conducting tube sinking and excitation; thirdly, keeping vibration; fourthly, pulling and moving tubes; fifthly, reinforcing surface soil; sixthly, leveling places. The method has the advantages that the foundation soil which is loose and needs to be reinforced can be effectively reinforced, the aims of eliminating collapsibility, liquidation and self-weight consolidation settlement of the foundation soil, improving foundation stability and foundation bearing capacity, reducing uneven settlement deformation and the like can be achieved, construction is convenient, rapid, effective and low in manufacturing cost, no building materials are needed, no pollutant is generated in the construction process, and the method is environmentally friendly.

Description

technical field [0001] The invention relates to the technical field of foundation treatment, and relates to an immersed tube excitation compaction method and a foundation treatment technology for reinforcing loose and under-consolidated foundation soil. Background technique [0002] The ground treatment technology of the dynamic compaction method is to use a large crawler crane to freely drop a heavy hammer of a certain mass from a certain height to compact the soil strongly. The vibration wave generated by the rammer impacting the foundation soil squeezes the soft soil during the transmission process of the deep soil, so that the soil particles are rearranged, the water and gas in the soil are discharged, and the soil becomes dense, so as to achieve the reinforcement of the deep foundation soil the goal of. The vibration source of the dynamic compaction method is located on the surface, and the vibration intensity decays rapidly when the vibration wave is transmitted to th...
