Embodiment 1
[0013] Such as figure 1 As shown, the construction process of the air-permeable layer without sand inclusions on the soft soil foundation:
[0014] ①Clear and level the surface of the soft soil foundation.
[0015] ② Arrange horizontal and vertical drainage facilities on the reinforced site to form a three-dimensional drainage system, arrange sealing membranes, use pumps and vacuum pumps to pump water along the drainage system, and carry out vacuum preloading for about 30 days to promote the soft soil foundation to partially consolidate. The degree of consolidation reaches more than 70%.
[0016] ③ Unloading, peel off the vacuum preloaded sealing film.
[0017] ④ Carry out strong compaction, heavy compaction or compaction construction.
[0018] Before dynamic compaction, heavy compaction or compaction reinforcement, a representative site should be selected for trial compaction to determine the construction technology and construction parameters of dynamic compaction, heavy ...
Embodiment 2
[0021] Such as figure 2 As shown, the construction process of the air-permeable layer with sand inclusions on the soft soil foundation:
[0022] ①Clear and level the surface of the soft soil foundation.
[0023] ②At the boundary of the reinforced site, for the sections with permeable and air layers within 10 meters underground, continuously lap the silt mixing piles and insert plastic sealing films to form a sealing wall for sealing.
[0024] ③ Arrange horizontal and vertical drainage facilities to form a three-dimensional drainage system, arrange sealing membranes, use pumps and vacuum pumps to pump water along the drainage system, and carry out vacuum preloading for about 30 days to promote the soft soil foundation to achieve partial consolidation. The degree reaches more than 70%.
[0025] ④ Unloading, peel off the vacuum preloaded sealing film.
[0026] ⑤ In order to ensure that the groundwater level will not rise during the process of dynamic compaction, heavy compact...
