Improved structure of soft ground with lattice type bulkhead for prevention of uneven settlement and leakage of leachate and its construction method

摘要

The present invention relates to an improvement of a soft ground of a wetland or a marsh such as a muddy pile accumulated in a river or a canal such as a waterway, especially a landfill by a dredge of a coastal dredge (reclaimed land), and a reservoir such as a reservoir and a reservoir, The present invention relates to an improved structure of a soft ground having lattice type barrier ribs for preventing settlement and leakage of leachate, and a method of constructing the same. The embedding zone (11) is divided into several unit areas (12) A partition wall 16 having a spacing of preferably 30-50 m, which is partitioned at regular intervals according to the soil condition according to the zones 12, is continuously installed and mixed with cement and mixed solidifying agent in the field soil of the gritted soft ground The agitated modified soil is laid down on the bottom layer 17 and the slope layer 18 as the secondary structure to form a solidification treatment layer and the inside of the partition 16 as a separate structure integrally constructed with the bottom layer 17 By assembling a box-shaped reinforced structure 19 made of a synthetic resin net 20 and filling the modified soil with the formwork, the self-strength of the anchored structure is increased to improve the supporting force against the upper load, And a lattice type partition wall for preventing uneven settlement and leakage of leachate by integrally forming all of the following structures, and an improved construction method of the soft ground.
