The steel-pipe pile cap overwater bottom-hanging device as claimed in claim 1, wherein the positioning frame comprises an inner cylinder and an outer cylinder which are vertically and coaxially sleeved, and a reinforcing mesh which connects the inner cylinder and the outer cylinder, the upper edge and the lower edge of the inner cylinder are both horizontally turned towards the axis of the inner cylinder, the upper edge and the lower edge of the outer cylinder are both horizontally turned away from the axis of the outer cylinder, the reinforcing mesh is provided with the positioning holes, wood blocks are annularly arranged on the inner side of the inner cylinder and the outer side of the outer cylinder, and the horizontal thickness of each wood block is larger than the turning width of the inner cylinder and the outer cylinder.
5. The steel-pipe pile cap water bottom-hanging device of claim 1, wherein the length ratio of the cubic column to the cylinder is 1: 3.
6. The construction method of the steel pipe pile cap water bottom-hanging device according to claim 1, characterized by comprising the steps of:
the method comprises the following steps that firstly, a sliding sleeve is sleeved on a cubic column from top to bottom and is in contact with a ring blocking piece, four clamping columns of a balancing stand are respectively inserted into the cubic columns of four hanging bottom pieces of a hanging bottom mechanism, and a pair of right-angled trapezoid elastic blocks of an elastic lock arranged on the clamping columns horizontally extend into through holes to enable the clamping columns to be connected with the cubic column, so that the assembly of the hanging bottom mechanism and the balancing stand is completed;
step two, arranging a positioning frame at the periphery of the steel pipe pile, and moving the bottom hanging mechanism and the balance frame assembled in the step one by a hoisting device through a hoisting rib, so that cylinders of four bottom hanging pieces are respectively inserted into four positioning holes of the positioning frame and are fixed from the lower end of the cylinder through nuts, and the assembly of the bottom hanging mechanism, the balance frame and the positioning frame is completed to form a supporting system;
thirdly, laying battens, boards and multilayer boards above a positioning frame of the supporting system from bottom to top in sequence, and adjusting the positions of nuts on the cylinders to enable the upper surfaces of the multilayer boards to be in contact with the lower surfaces of the ring stoppers to form a pile cap suspended bottom template;
separating the sliding sleeves of the four bottom hanging pieces from the located cubic columns, controlling the sliding sleeves to slide upwards, enabling the right-angled trapezoidal elastic blocks of the pair of elastic locks arranged on the clamping columns to retract from the through holes when the sliding sleeves slide upwards, and continuing to slide upwards until the pair of magnetic suction cups are adsorbed on the lower surfaces of the four balance beams;
and fifthly, pouring reinforced concrete on the pile cap suspended bottom template to finish the overwater pile cap suspended bottom.
