Vacuum preloading reinforcement construction method applicable to underwater silt environment
The invention discloses a vacuum preloading reinforcement construction method applicable to an underwater silt environment. The vacuum preloading reinforcement construction method includes the following steps that a first layer of sand cover soft mattress is laid; plugboard construction is conducted; a level discharge pipe line is laid; a second layer of sand cover soft mattress is laid; geo-nonwoven cloth and a sealing membrane are laid; around reinforcement area sealing system construction is conducted; vacuumizing is conducted until dead load is finished. The vacuum preloading reinforcement construction method applicable to the underwater silt environment effectively solves the related problems encountered in engineering constructions of an inland river, an intertidal belt and an abyssal region, such as large excavation workload, a long construction period and high building cost of projects in an underwater excavation work and a bank slope treatment project of a long-piled wharf, large using amount of stones, a long construction period and high building cost of projects in reinforcing breakwater foundation construction adopting methods of overwater throwing-filling rock blocks, land pushing throwing-filling breakwater core rocks and explosion discharging slit backfilling rock blocks, and large excavation and filling amount in a traditional replacement method.
