[0017] The specific technical solutions of the present invention will be further described below with reference to the accompanying drawings, so that those skilled in the art can further understand the present invention, without limiting their rights.
[0018] refer to figure 1 and figure 2 , a sandless vacuum preloading soft soil foundation reinforcement method, through two stages to strengthen the soft soil foundation, the first stage is the pre-consolidation treatment of the shallow surface layer, when the bearing capacity of the shallow surface layer reaches the set value, the second stage is carried out Stage deep long slab vacuum preloading reinforcement treatment,
[0019] Specific steps are as follows,
[0020] The first stage of shallow surface pre-consolidation treatment: First, dig a pressure film ditch 1, lay a layer of woven cloth on the surface of the soft ground to provide bearing capacity for the subsequent laying of the vacuum pipe network, and then lay the...
