Example Embodiment
[0027] Example 1: Such as figure 1 As shown, a double-row pile supporting structure that can make full use of the basement space is composed of front row piles 1, back row piles 2, crown beam I3, crown beam II4, connecting beam I5, water-stop curtain pile 6, basement 7, Engineering pile 8, plain concrete 9, layered rammed fill 10, negative basement bottom plate 12, negative two-story basement bottom plate 13, and connecting beam Ⅱ 14. The front row of piles 1 has crown beam I3 on the top of the pile, and the rear row of piles The top of the pile 2 is equipped with crown beam Ⅱ4, the top of the front row of piles 1 and the back row of piles 2 are connected by connecting beam Ⅰ5, and the soil behind the back row of piles 2 is equipped with water-stop curtain piles 6. The site is leveled according to the design Construction of all engineering piles 8, pour a connecting beam Ⅱ14 on the top of the pile 1 after the removal, and pour the connecting beam Ⅱ14 and the basement bottom p...
Example Embodiment
[0042] Example 2: Such as figure 1 As shown, it is basically the same as Example 1, and the difference:
[0043] A construction method of a double-row pile supporting structure capable of making full use of the basement space. The length of the front row of piles 1 can be designed to be greater than the length of the rear row of piles 2.
Example Embodiment
[0044] Example 3: Such as figure 1 As shown, it is basically the same as Example 1, and the difference:
[0045] A double-row pile supporting structure that can make full use of the basement space. The pile bodies of the front row piles 1 and the rear row piles 2 are arranged in a T-shaped array and are spaced apart from each other.
