Problems solved by technology

[0004] However, in the above-mentioned related technologies, only the gravity of heavy objects can be used to drain the soft soil foundation, so as to realize the consolidation and compaction of the soft soil foundation soil, and this generally takes half a year of construction time, and the construction period is long

Embodiment Construction

[0042] The following is attached Figure 1-6 The application is described in further detail.

[0043] The embodiment of the present application discloses a soft ground reinforcement method, comprising the following steps:

[0044] S1, refer to figure 1, open a vertical cylindrical foundation hole 1 on the horizontal foundation;

[0045] S2, refer to figure 1 and figure 2 , install a cylinder 2 in the foundation hole 1, the cylinder 2 is arranged coaxially with the foundation hole 1, and one end of the cylinder is arranged in close contact with the bottom of the foundation hole 1, the cylinder 2 includes an outer column 22 and an inner column 23, the outer column 22 It is hollow cylindrical and the upper and lower ends are open, the inner column 23 is cylindrical, the inner column 23 and the outer column 22 are coaxially arranged, and the outer side of the inner column 23 is close to the inner side of the outer column 22, and the outer side of the inner column 23 is fixed ...

Abstract

The invention relates to the field of building construction, in particular to a soft soil foundation reinforcing method. The soft soil foundation reinforcing method comprises the steps that a plurality of base holes perpendicular to the main bearing direction of a foundation are formed in the foundation; columns are hoisted in the base holes; water pumps are arranged in the columns, and pipelines at outlet ends of the water pumps are mutually connected through vacuum pipes to form a pipeline structure; a sealing structure is arranged on the foundation; a vacuum pump is arranged on the pipeline structure; a water-gas separator is arranged between the outlet end of the pipeline structure and the vacuum pump; the liquid outlet end of the water-gas separator is fixedly connected with a water storage tank; and after water in soil of the foundation is pumped till the consolidation degree of the soil meets the construction requirement, inner columns are taken out of the base holes through a crane, prefabricated concrete columns are hoisted on the inner sides of outer columns, and finally the outer side of the foundation is filled and leveled up for reinforcement treatment. The method has the effect of reducing the consolidation time of a soft soil foundation.

Description

technical field [0001] The application relates to the field of building construction, in particular to a method for strengthening soft ground. Background technique [0002] Soft soil foundation refers to the soft soil mainly composed of clay and silt and other fine particles, organic soil with large pores, peat, and loose sand. subsidence of the ground. [0003] In order to prevent the settlement of the soft soil foundation, the relevant technologies usually use pre-stacking enough heavy objects such as rockfill or soil pile on the soft soil foundation, and pre-press the foundation to make the soil consolidate and compact, so as to strengthen the soft soil foundation. Shorten the preloading construction time, set up sand wells, plastic drainage pipes, etc. in the soft soil foundation for drainage, so as to accelerate the clay consolidation process. [0004] However, in the above-mentioned related technologies, only the gravity of heavy objects can be used to drain the soft...
