A processing method on the basis of the tower crane

1. In front floor mat concrete tower crane  earthwork excavation, so Taki top elevation below the bottom end elevation 120mm, which is reserved for settlement.
   2. Press the tower crane foundation construction tower construction plans until after a certain intensity installation crane.
   3. Taki four weeks cushion concrete construction. Taki top with clayey soil cover 100mm, add a touch of 20mm mortar, the entire pad on the same elevation level.
   4. According to the drawings floor, floor muscle (double two-way) are passing through the bottom section of the tower crane; the paint when poured concrete floor, rust cleaned, and the welding of this section standard section waterproof plate poured in concrete.
   5. Standard sections can be cut from the floor over time removed.

The only disadvantage of the above approach is to cut off a section standard section. Do not stay if cut standard section, then pouring the concrete floor of the tower location is not poured until the Chai Wan crane then pouring this concrete, but this resulted in the floor construction joints, while there may be a large number of groundwater infiltration in the basement during construction, waterproofing need to make sure, otherwise not conducive to the construction and safety. By Taki Regardless natural foundation or pile, this approach will adapt. The company has a total of two towers have two podium engineering application of this approach, the effect is very satisfactory.
