Embodiment 1
[0020] A method for preparing a road / site foundation under a silty soft soil environment, comprising the following process steps:
[0021] 1) Spread the curing agent evenly on the working area in the muddy soft soil;
[0022] 2) For the operation area where the curing agent has been sprayed in step 1), use an excavator to excavate the silty soft soil in the operation area until the foundation trench is formed, and make the silt on the excavator during each excavation process Mix soft soil and curing agent evenly;
[0023] 3) Lay the silty soft soil mixed with curing agent in step 2) into the foundation groove layer by layer; each time a layer of silty soft soil is laid, it is rolled and formed by rolling equipment;
[0024] 4) When the thickness of the multi-layer silty soft soil in step 3) reaches the set thickness, cover and maintain the silty soft soil in the foundation trench through the film.
[0025] The method for preparing the road / site foundation under the silty sof...
Embodiment 2
[0027] As an improvement of the present invention, in the step 2), the volume of the muddy soft soil excavated in each excavation process of the muddy soft soil in the operation area by the excavator is the same. By adopting the above technical solution, it is possible to effectively control the mixing effect of the muddy soft soil and the curing agent through the quantitative excavation treatment of the muddy soft soil, thereby improving the overall curing effect of the muddy soft soil.
[0028] The remaining features and advantages of this embodiment are the same as those of Embodiment 1.
Embodiment 3
[0030] As an improvement of the present invention, the method for preparing the road / site foundation under the muddy soft soil environment includes the following process steps:
[0031] 2.1) On the working area in the silty soft soil, excavate the silty soft soil in the working area with an excavator until the foundation trench is formed; for each excavated silty soft soil, pass the curing agent through The pipeline is injected into the corresponding silty soft soil, and the mixing with the silty soft soil is completed;
[0032] 2.2) Lay the silty soft soil mixed with curing agent in step 2.1) into the foundation trench layer by layer; every time a layer of silty soft soil is laid, it is rolled and formed by rolling equipment;
[0033] 2.3) When the thickness of the multi-layer silty soft soil in step 2.2) reaches the set thickness, cover and maintain the silty soft soil in the foundation trench through the film.
[0034] By adopting the above technical solution, it is possib...
