Embodiment Construction
[0025] Such as figure 1 , 2 As shown in and 3, a pile with a hollow core slurry-solid-dispersion material is composed of a prefabricated pipe pile (1), a slurry-solid-dispersion material (2) and a slurry diffusion zone (3), and the interior of the prefabricated pipe pile (1) is filled with The grout (4), the prefabricated pipe pile (1) has a grouting hole (5) on the pile wall. The diameter of the pile body formed by the present invention is 500-700 mm, and the diameter of the prefabricated pipe pile (1) is 200-300 mm.
[0026] A construction method of a hollow core slurry solid-dispersion material pile, the construction steps of which are as follows:
[0027] The first step is to form a hole. The hole forming process of the grouted pile is basically the same as that of the general bored pile. Generally, a drilling rig is used to form a hole, and the natural pulping wall is used. When the hole wall is not easy to maintain, the artificial pulping wall is used. In engineerin...
