Multifunctional vibrating air compressor pipe and construction method adopting same for soft soil foundation reinforcement

Abstract

The invention relates to air compressor reinforcement equipment. The air compressor reinforcement equipment comprises a vibrating hammer (2) and a vibrating air compressor pipe (9), wherein the vibrating air compressor pipe (9) is a seamless steel pipe; the vibrating hammer (2) is connected with the top of the vibrating air compressor pipe (9); a vibrating hammer center hole (1) of the vibrating hammer (2) and the vibrating air compressor pipe (9) are located in the same perpendicular line; a top end (3) of the vibrating air compressor pipe (9) is a closed valve; an air injection port (6) is formed in one side of the vibrating air compressor pipe (9); an air injection port valve (7) is arranged at the air injection port (6); a conical valve formed by multiple valve clacks (10) is arranged at the lower end of the vibrating air compressor pipe (9). When applied to soft soil foundation reinforcement construction, the air compressor reinforcement equipment mainly solves the problem that deep reinforcement of a soft soil foundation cannot be realized with an existing process and particularly silt soil and silt interlayer soil after reinforcement cannot meet various technical indexes required by design, the air compressor reinforcement equipment is high in operability, simple and practical and has quite board application prospect, and the technology is advanced.

Description

technical field [0001] The invention relates to a multi-functional vibrating air pressure pipe and a construction method for reinforcing soft soil foundations using the same, which is mainly used in soft soil foundation reinforcement methods, is suitable for rapid reinforcement treatment of soft soil foundations, and belongs to the technical field of foundation treatment. Background technique [0002] At present, in the process of strengthening large-area soft soil foundations, the "precipitation dynamic compaction method" is often used. By inserting well point pipes or plastic drainage boards, ditching open rows and other processes into the soft soil foundations that need to be reinforced, the groundwater reduction is greatly reduced. Under the condition of location, multi-pass dynamic compaction is used to achieve the purpose of soft soil foundation reinforcement. [0003] However, in the actual construction process, the impact energy of dynamic compaction on soft soil fou...

AI Technical Summary

Problems solved by technology

Since dynamic compaction requires high optimum water content of the soil, dynamic compaction in silt soil will not only fail to achieve the required reinforcement effect, but will damage the soil structure due to the poor permeability coefficient of the silt soil. Difficult to recover from silt
