A construction method for strengthening dredger-filled sand embankment

Abstract

The invention discloses a construction method for reinforcing a dredged sand embankment. A cement blanket water-repellent layer is horizontally laid on the bottom of the embankment, and a plurality of dredged sand reinforced layers are laid on the upper layer of the cement blanket water-resistant layer, and each layer of the dredged sand reinforced layer is Including the geogrid and the sand booth filled in the geogrid, the long cement blanket is prefabricated into equilateral and 120° cell strips, and the cell strips are placed in pairs along the embankment. Arranged symmetrically to form a regular hexagonal honeycomb geocell network, the geocell network is placed on the cement blanket at the bottom of the embankment, the geocell network is filled with sand stalls, and the filled sand stalls are rolled back and forth After the dredging sand is filled, static rolling and watering maintenance are carried out. This construction method belongs to physical reinforcement. While assisting in improving the strength of the dredged sand, it can also improve the overall stability of the embankment through the reinforcement connection, effectively preventing uneven settlement and Lateral deformation.

Description

technical field [0001] The invention relates to a construction method for reinforcing dredged sand embankment. Background technique [0002] At present, embankments at home and abroad are generally filled with earth and stone. The construction technology is mature, and the embankment construction quality is high and the stability is good. However, some special soil areas, such as coastal areas, are rich in island and reef resources, and the sea area contains a large amount of calcareous coral reef sand, which has large reserves, but the utilization rate is extremely low. At present, the country pays more attention to the development of land reclamation technology in the marine field, but most of them are land reclamation by dredging mud in coastal areas, and the technology of reclamation and reinforcement by dredging reef sand for remote islands is still immature. Generally, the cofferdam is filled by transporting earth and stone over long distances. On the one hand, it inc...

AI Technical Summary

Problems solved by technology

Generally, the cofferdam is filled by transporting earth and stone over long distances. On the one hand, it increases the project cost to a certain extent, and on the other hand, it causes a waste of local resources.
