Embodiment Construction
[0043] The caisson process is used on land, and the soil within the sinking range of the caisson must be removed. The removal method can be mechanical removal or other methods.
[0044] The invention provides a method for using high-pressure water to wash the soil under a box into mud, and then pumping the mud away, so that the caisson continuously sinks in place as the soil layer under the box drops.
[0045] With this method, you must first determine whether there are obstacles in the soil layer in the range, see Picture 10 The method of judgment is as follows: In addition to drilling to understand the condition of the soil layer, a probe point is made every 1.5 meters to form a well-shaped distribution. The probe can be used to insert the iron rod, manual hammer penetration, or other mechanical detection methods. If it is found that there are large boulders or other obstacles in the sinking area of the caisson, the treatment methods are as follows: a. First carry out undergr...
