Composite reinforcing method for combining soft foundation light well point pipe with plastic drainage plate
A technology of plastic drainage boards and light well points, which is applied in infrastructure engineering, soil protection, construction, etc. It can solve the problems of muddy sites, spring soil, and the inability to reduce the water content of the silt interlayer soil, and achieve the water content of the soil. The effect of balance, short construction period, and cost-effective improvement

[0032] The specific process steps of this method are as follows (dynamic consolidation takes dynamic consolidation as an example):
[0033] Step 1: Excavate the drainage ditch
[0034] For large-area weak foundations, adopt light well plastic drainage point dewatering reinforcement technology, and then several communities can be set up in the area to be reinforced. Generally, a community is 5000~10000m 2 . Open trenches are excavated between the communities, and the open trenches between the communities are connected to each other to form a drainage network. A certain number of water collection wells are set at the junction of the open trenches, and the open ditch water is discharged into adjacent rivers by gravity or forced drainage.
[0035] Step 2: Arrange composite well points formed by light-weight well point pipes combined with plastic drainage plates (referred to as light well plastic drainage well points) and vacuum composite well points for dewatering
