Problems solved by technology

However, if the muddy soil in the pit is not drained, it will easily lead to muddy ground in the foundation pit, subsidence of the excavator, deformation of the enclosure structure, and pollution of the environment due to excessive water content during transportation.
The existing dewatering method is to lay out pumping wells in the formation, and reduce the water head at the wellhead to generate hydraulic gradient precipitation. However, due to the poor permeability of muddy soil, drainage is difficult.
The above dewatering methods cannot effectively meet the dewatering requirements in the construction of muddy soil foundation pits, and it is urgent to study new dewatering techniques and methods to solve related problems

Embodiment Construction

[0030] The present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0031] Such as figure 1 , 2 , 3, a kind of muddy soil dewatering and dewatering system with ground excitation boosting and vacuum well is arranged in the foundation pit for dewatering and dewatering of muddy soil in the pit, including several vacuum drainage wells 31 arranged in the foundation pit and located in the foundation pit. The vibration booster between adjacent vacuum drainage wells 31, the vibration booster includes a vibrator 15 and a force transmission pipe 13 located at the bottom of the vibrator 15, the force transmission pipe 13 is a round pipe, and the lower part is inserted into the soil Among them, the vibration generated by the exciter 15 is transmitted to the deep muddy soil layer through the force transmission pipe 13 and generates excess pore pressure, which can increase the remote pore water pressure of the underlying ...

Abstract

The invention relates to a muddy soil unwatering and dewatering system with ground excitation and boosting matched with vacuum wells. The muddy soil unwatering and dewatering system comprises the multiple vacuum drainage wells arranged in a foundation pit and excitation and boosting devices arranged between the adjacent vacuum drainage wells; each excitation and boosting device comprises a vibration exciter and a force transmission pipe fitting arranged on the lower portion of the vibration exciter, wherein the force transmission pipe fitting is a round pipe, the lower portion of the force transmission pipe fitting is inserted into soil, vibration generated by the vibration exciter is transmitted into a deep muddy soil layer through the force transmission pipe fitting, super-pore pressure is generated, the far-end pore water pressure of the underlying muddy soil layer can be increased, and the drainage purpose is achieved. Compared with the prior art, by means of the manner of increasing the far-end water pressure and reducing the wellhead water pressure, the seepage hydraulic gradient is increased, solidification of muddy soil is accelerated, and the unwatering requirement of the muddy foundation pit can be rapidly met.

Description

technical field [0001] The invention belongs to the technical fields of geological engineering, geotechnical engineering, tunnel and underground construction engineering, and dewatering engineering, and in particular relates to a muddy soil dewatering and dewatering system and method using ground excitation and pressure boosting combined with a vacuum well. Background technique [0002] At present, during the construction of muddy soil foundation pits, due to the unique characteristics of high water content, high compressibility, high rheology, low strength, and low permeability of muddy soil, that is, three highs and two lows, it is difficult to drain water. However, if the muddy soil in the pit is not drained, it will easily lead to muddy ground in the foundation pit, subsidence of the excavator, deformation of the enclosure structure, and environmental pollution due to excessive water content during transportation. The existing dewatering method is to lay out pumping well...
