Abstract

The invention discloses a coastline soft foundation in-situ curing method and curing structure. The coastline soft foundation in-situ curing method comprises the following steps that S100, construction equipment is arranged; S200, surveying, setting out and positioning are conducted; S300, a solidified area is excavated; S400, in-situ curing operation is conducted; S500, a solidified foundation is backfilled; S600, side edge concrete encapsulation is conducted; and S700, shaping and maintenance are conducted. The invention further provides the coastline soft foundation in-situ curing structure which comprises a curing foundation pit, soil turning pits are dug in the two sides of the curing foundation pit, geogrids are laid in the center of the curing foundation pit, the curing foundation pit and the soil turning pits are filled with curing soil retaining walls, and a concrete envelope is laid at the corresponding positions of the outer sides of the top surfaces of the curing soil retaining walls. The curing method and structure can be effectively suitable for coastline soft foundation solidification of an ecological wetland section, the construction process and machinery are simple, the construction progress is fast, the construction quality is high, and the construction cost is low.

Description

technical field [0001] The invention relates to the technical field of coastline construction, in particular to an in-situ curing method and a curing structure for a coastline soft foundation. Background technique [0002] Commonly used soft foundation curing methods are vacuum preloading and backfilling. The vacuum preloading method is to mechanically insert drainage pipes into the mud pool, connect the drainage pipes and spread plastic film, pad sand with a thickness of 0.5 meters, then pump in seawater to form pressure, and then use a vacuum pump to pump air and drain water. Due to the large area of ​​reclamation sea mud for land reclamation (land), generally the area of ​​each mud pool is 500,000-1 million square meters, and the water content of sea mud is large, generally the water content is 45% to 50%. Fine, the particle diameter is generally below 2mm, and the sea mud depth is large, generally 4-6 meters. Vacuum preloaded intubation machines cannot be inserted into...
