Embodiment Construction
[0046] The present invention will be described in further detail below with reference to the accompanying drawings and specific preferred embodiments.
[0047] like figure 1 As shown, a valve type concrete sheet pile hole forming device includes a steel formwork 10 and a valve type pile shoe 30 .
[0048] The center of the steel formwork is provided with a pouring cavity 13 with a rectangular section, and the length-width ratio of the rectangular section of the pouring cavity is increased.
[0049] The top of the steel formwork or the top of the side wall is provided with a concrete pouring sprue 11 .
[0050] like figure 2 As shown, several stiffening plates 12 are preferably uniformly distributed on the outer wall of the steel formwork along the circumferential direction, and both the steel formwork and the stiffening plates are preferably high-strength steel plates. Each reinforced slab is preferably arranged vertically, so the overall rigidity of the steel formwork can...
