[0036] Example 1
[0037] Such as figure 1 As shown, the present invention discloses a construction process for deep and thick soft foundation treatment, which is characterized in that the construction process adopts a plastic drainage board 3 for deep pretreatment, and then a cement mixing pile 4 is used for secondary shallow reinforcement treatment. Specifically includes the following steps:
[0038] Calculation of foundation treatment parameters:
[0039] In this process, the upper silt is reinforced with cement mixing pile 4, and the settlement control of deep silt is treated with plastic drainage board 3. The calculation mode is divided into the upper soft soil layer using composite foundation reinforcement area, and the lower soft soil layer is the drainage preloading treatment area. The specific foundation bearing capacity and settlement of different reinforced soil layers are calculated as follows:
[0040] Settlement calculation:
[0041] The settlement of the foundation is b...
Example Embodiment
[0058] Example 2
[0059] This embodiment is based on the construction process steps described in embodiment 1, taking the Gangbei Road (West Section) project in Xiamen as the construction object for implementation verification.
[0060] The road is classified as an urban arterial road with a total length of 1.445km. The original geomorphic unit of the road section is a bay beach. There is generally a deep soft foundation over 12m, and the deepest silt is about 20m. The original design adopts CFG pile treatment to deal with deep penetrating silt , The plane layout adopts equilateral triangle layout, the spacing is 1.4m, the average processing depth is about 18m, and the average cost per square meter is about 630 yuan. After the process of the present invention is adopted, the average treatment depth of the plastic drainage board 3 is 18m, and the plane layout adopts a 1.2m interval and a regular triangle arrangement. The cement mixing pile 4 undergoes a secondary treatment depth of...
