Example Embodiment
[0019] Example 1
[0020] A curing method for rapidly forming a hard shell layer on the surface of a storage yard, the method includes the following steps:
[0021] (1) Start the sludge curing machine 4, and mix and stir the sludge and the curing material (lightweight materials such as EPS particles, broken rubber particles, etc. can also be added);
[0022] (2) After mixing, use the excavator 5 to lay on the surface of the yard;
[0023] (3) After the solidified silt is laid and hardened (about 1 to 2 days), manual or light paving machinery can drive up the hard shell layer, and then lay it forward in sequence until the entire silt yard is full.
Example Embodiment
[0024] Example 2
[0025] A curing method for rapidly forming a hard shell layer on the surface of a storage yard, the method includes the following steps:
[0026] (1) Start the sludge curing machine 4, and mix and stir the sludge and the curing material (lightweight materials such as EPS particles, broken rubber particles, etc. can also be added);
[0027] (2) After mixing, use the mud pump 6 to lay on the surface of the yard;
[0028] (3) After the solidified silt is laid and hardened (about 1 to 2 days), the construction personnel can walk on the surface of the hard shell layer laid before, and then extend the mud pump mud pipe forward and lay it in sequence until the entire silt storage yard Paved.
Example Embodiment
[0029] Example 3
[0030] A curing method for rapidly forming a hard shell layer on the surface of a storage yard, the method includes the following steps:
[0031] (1) Sprinkle the solidified material on the silt surface manually or mechanically,
[0032] (2) Use the in-situ sludge curing machine 8 to mix and stir the sludge and the curing material 7 on the spot;
[0033] (3) After the solidified sludge is stirred and hardened (about 1 to 2 days), the manual or light in-situ curing machine can drive up the hard shell layer laid in front, and then lay it forward in turn until the entire silt yard is full .
