Sand dredger filling construction method of soft soil foundation embankment

Abstract

The invention discloses a sand dredger filling construction method of a soft soil foundation embankment. The sand dredger filling construction method comprises the steps of: (1) cleaning the surface of an embankment dredger filling field; (2) measuring and lofting, and setting an elevation mark of the dredger filling construction in a dredger filling region; (3) performing the dredger filling work in a manner of segmenting and layering, to be specific, forming a cofferdam, establishing plastic water discharge plates, building construction roads, distributing grit blasting pipe lines, dredger-filling the embankment, constructing a drain opening, and constructing water collecting wells; and (4) performing stability observation and settlement observation on the dredge-filled sand land of the embankment. The sand dredger filling construction method disclosed by the invention has the advantages of solving the flatness problem of road area at coastal tidelands, rivers, fishponds and the like, performing roadbed filling of municipal administration by fully making use of the characteristics of abundant fin sand resource in the local area, reducing exploitation usage amount of the land resource, decreasing construction cost while guaranteeing construction quality of the roadbed, being simple, convenient, feasible, efficient and practical, increasing working efficiency, saving cost and creating conditions for advanced construction of the next procedure.

Description

technical field [0001] The invention relates to a municipal road embankment construction method, in particular to an embankment dredging and sand filling construction method for fish ponds, river gushes, and soft soil foundations along beaches. Background technique [0002] With the development and opening up of coastal areas, land as a scarce resource can no longer meet the needs of urban development. Most of my country's coastal coastlines are muddy coasts, especially the coastal areas, large rivers, and the vicinity of large river estuaries are flat, soft soil is widely distributed, and geological conditions complex. When constructing port projects in coastal areas, due to the low terrain and lack of backfill, land is often formed by dredging. How to properly deal with the dredger fill soft soil foundation can not only ensure the quality of the project, but also save investment, which plays a very important role in the construction of coastal areas and economic developmen...

AI Technical Summary

Problems solved by technology

[0003] The soft soil foundation is usually floodplain-beach landform, with many pools, thick silt layer, difficulty in building access roads, and shortage of soil sources

If the ordinary embankment filling method is used, it is necessary to build access roads and occupy farmland, the transportation cost is high, and it also pollutes the environment, the construction cost is high, and the construction period is long
