Horizontal drainage system for consolidating soft foundation and construction method of horizontal drainage system

Abstract

The invention discloses a horizontal drainage system for consolidating a soft foundation. The horizontal drainage system comprises a drainage cushion layer laid on the foundation, a plurality of vertically arranged vertical drainage plates and a plurality of vertically arranged vertical water collecting pipes; the vertical drainage plates and the vertical water collecting pipes are arranged in a staggered manner, and the vertical drainage plates and the vertical water collecting pipes are uniformly distributed in the foundation; the upper ends of the vertical water collecting pipes protrude out of the surface of the foundation, and the rest parts of the vertical water collecting pipes are buried in the foundation; and the upper ends of the vertical drainage plates protrude and extend into the drainage cushion layer, and the rest parts of the vertical drainage plates are buried in the foundation. The vertical plastic drainage plates and the vertical water collecting pipes are arranged in the foundation, and meanwhile, horizontal plastic drainage plates and horizontal connecting pipes are arranged, so that the consolidation drainage efficiency is greatly improved, and the system has the advantages of being environmentally friendly (saving resources), low in cost and short in construction period (factory modular production and field installation).

Description

technical field [0001] The invention relates to the technical field of drainage systems, in particular to a horizontal drainage system for consolidating soft foundations and a construction method thereof. Background technique [0002] The drainage consolidation method is often used in the soft foundation consolidation process. The drainage consolidation method is to vertically implant drainage (filter) water channels within the scope of the soft foundation to be treated, and then pile up a certain level of piles on the top to squeeze out After the water in the compacted soil penetrates into the drainage (filter) channel, it is discharged from the horizontal sand cushion to achieve the purpose of stabilizing the soft foundation. Traditional drainage consolidation methods include vacuum preloading, surcharge preloading, and vacuum combined surloading preloading. The principle is to embed plastic drainage boards (belts) with water filtering functions into the soft and fluid pla...

AI Technical Summary

Problems solved by technology

[0003]The traditional drainage consolidation method has many disadvantages: 1. The sand cushion must be used, but the construction cost is high due to the lack of sand resources; 2. The sand cushion is in the During the construction process, secondary pollution will be caused due to cross operations. The originally clean sand will be polluted once after being paved (contaminants include soil carried by mechanical equipment), and will be polluted again when laying plastic drainage boards, making the sand cushion The water permeability performance is greatly reduced; 3. It is difficult to pave the sand cushion
