Problems solved by technology

The above-mentioned drainage consolidation method has a very long construction period, usually six months to one year to complete, so the construction cost is very high and the efficiency is very low
[0004] The above drainage consolidation method is only suitable for large area construction
Moreover, since the height of the piled load is limited, it cannot be ap...

Embodiment 1

[0156] The treatment method of backfilling and placing reinforced module pressure-bearing pile composite foundation structure is as follows:

[0157] 1) Reference Figure 28 , Use a hoist 18 to hoist the modular soil pressure forming device 19 to the current construction area.

[0158] 2) Reference Figure 29 , The modular soil pressure forming device 19 applies vibration pressure to the soil, and the self-weight of the modular soil pressure forming device 19 applies longitudinal static pressure to the soil; the impact hammer 13 applies longitudinal impact to the soil The vibration device 15 causes the device 19 to vibrate, and then applies high-frequency lateral pressure to the soil; the above three combined forces act on the soil to fully compress the soil, and the moisture in the soil is reinforced The body 5, the filter device 4 and the water guiding channel 203 on the convex body reach the water collection chamber 5, and then are drawn out through the pumping pipe 10. The pum...

Embodiment 2

[0164] Reference Figure 32 , The treatment method of backfilling and placing reinforced module pressure-bearing pile composite foundation structure is as follows:

[0165] 1) The crane hoists the modular soil pressure forming device to the current construction area.

[0166] 2) The modular soil pressure forming device performs compression, compaction, drainage and consolidation of the soil to form a pit. The bottom of the pit forms a shaped soil structure corresponding to the shape of the pressure forming module.

[0167] 3) The crane hoists the modular soil pressure forming device to the next construction area, and repeat step 2) until all construction areas are processed.

[0168] 4) Backfill a layer of sand and gravel aggregate 43-2 in the forming pit, then set up a filter device 65 with water filtration and circulating purification functions, and then lay sand and gravel aggregate 43-2 until the pit is filled, and 0.8~1M above the ground.

[0169] 5) Reshape and compact the backfi...

Embodiment 3

[0171] The treatment method of backfilling and placing reinforced module pressure-bearing pile composite foundation structure is as follows:

[0172] 1) Reference Figure 33 , The crane hoists the modular soil pressure forming device to the current construction area.

[0173] 2) The modular soil pressure forming device performs compression, compaction, drainage and consolidation of the soil to form a pit. The bottom of the pit forms a shaped soil structure corresponding to the shape of the pressure forming module.

[0174] 3) Cement concrete 66 is backfilled in the forming pit and vibrated with a vibrator to improve the density. The connecting member 52 is buried when the concrete is in a fluid state. The connecting member 52 is used to connect upper devices, such as light rails, iron towers, wind energy or solar energy devices, and the like.

[0175] 4) The crane hoists the modular soil pressure forming device to the next construction area, and repeat steps 2) and 3) until all const...

Abstract

The invention discloses a processing method of a bearing pile composite foundation structure via a backfilling disposing reinforcement module. The method is characterized by comprising the following steps, carried out on an undisturbed soil foundation or processed foundation, that 1) a modularized soil pressurizing and forming device carries out pressurizing compaction drainage and consolidation on the soil to form a pit; and 2) the molded pit is backfilled with at least one selected from A) modified soil, B) a granular material, C) concrete and D) a reinforcing tube bag wrapping the granularmaterial. The modularized soil pressurizing and forming device comprises a top rack, a pressurizing and molding module and a soil intensity detector, and the pressurizing and molding module comprisesprotruded bodies. The soil is extruded for drainage and molded rapidly, and the processing method is suitable for process reinforced composite foundations of coastal reclamation, roads and railways, airports, harbor stockyards, trestles, slope protection, dams, industrial and civil construction and the like.

Description

Technical field [0001] The invention relates to the field of foundation reinforcement treatment, in particular to the field of soft soil foundation reinforcement treatment, in particular to a method for backfilling and placing reinforced module pressure-bearing pile composite foundation structures. Background technique [0002] The soil structure is generally composed of a mixture of solids, liquid water and air. The different mixing ratios of various substances produce unequal pressure-bearing capacity. When the pressure is greater than the pressure of the soil, the pressure will cause side shift and compression. Settlement requires an artificial change in the mixing structure ratio of the undisturbed soil. Under the action of applied pressure, the density of solid particles in the soil is increased. The drainage material in the soil is used to discharge liquid water and The air channel changes the mixing structure of the soil to continuously increase the proportion of solids co...
