Embodiment Construction

[0055] A construction method on saturated soft ground, comprising the following steps:

[0056] (1) Construction preparation stage

[0057] For the saturated soft soil foundation, the working cushion must be done first, so that the reinforcement work can be carried out;

[0058] (1) Working cushion

[0059] The working cushion is composed of two processes of laying brambles and filling dry soil. The method is as follows: lay the brambles first, choose the flexible brambles of the year, and spread two layers in order on the surface of the saturated soft soil. Lap 200mm between them, and use 14~16# lead wires to bind firmly at a distance of 500mm, and the gaps between layers should be staggered; then fill with dry soil, if there is no dry soil or construction in rainy season, fill with mountain soil or earth and stone chips, the thickness is not large Less than 450mm; filling can only be carried out manually with a trolley;

[0060] (2) Spread the filter layer

[0061] The m...

Abstract

The invention provides a construction method for water-saturated soft soil foundations. The method comprises the steps of construction preparation, clay heavy curtain pile sealing wall construction, drain board insertion, pipe network laying and equipment installation, film pressing ditch digging, film sealing and pre-pressing. Compared with the conventional soft soil foundation processing methods such as dynamic compaction consolidation and powder-jetted piles, the method has the advantages of low production cost, remarkable consolidation effect, short construction period, energy conservation, environmental protection and low noise.

Description

technical field [0001] The invention relates to a soft soil foundation construction method. Background technique [0002] Low consolidation degree of saturated soft soil foundation, long construction period, and environmental pollution have always been difficult problems in the construction of soft soil foundation consolidation degree, which have become the main factors affecting the service life of saturated soft soil foundation. Contents of the invention [0003] The object of the present invention is to provide a water-saturated soft soil foundation construction method with remarkable reinforcement effect, shortened construction period, energy saving and environmental protection, and low noise. [0004] Technical solution of the present invention is: [0005] A construction method for saturated soft soil foundation is characterized in that it comprises the following steps: [0006] (1) Construction preparation stage [0007] For the saturated soft soil foundation, th...
