The invention discloses a tool type guiding pile-sinking device which comprises supporting anchor piles, wherein a guiding pile-sinking platform is supported on the supporting anchor piles; the guiding pile-sinking platform comprises a first layer platform and a second layer platform; the second layer platform is connected with the first layer platform; a guiding pile-sinking platform adjusting mechanism is arranged between the first layer platform and the top of the supporting anchor pile; a pile-holding mechanism for the supporting anchor pile is arranged on the first layer platform; a plurality of port position-adjusting mechanisms are arranged on and connected with the second layer platform; the port position-adjusting mechanisms are arranged on the second layer platform along the circumference; the pile-holding mechanism comprises supporting bases arranged on the first layer platform; a plurality of hydraulic cylinders are horizontally arranged on the supporting base; and the hydraulic cylinders are arranged along the circumference. Multiple direction adjustment is adopted; the multiple adjustment for the guiding pile-sinking platform and steel tube piles can be realized during a guiding pile-sinking construction process of bridge steel tube piles; and the tool type guiding pile-sinking device provided by the invention is used for ensuring the relative position precision of steel tube pipes while realizing the L / 400 vertical precision of single pile.
Description
technical field [0001] The invention belongs to the construction technology of bridge pile foundations, in particular to a guided pile sinking device for bridge steel pipe piles. Background technique [0002] Piling positioning of steel pipe piles is a key step in bridge construction. With the continuous innovation of bridge construction technology, the construction method of prefabricated cap pier body has emerged as the times require, which has higher requirements for the positioning accuracy of steel pipe piles. The traditional steel pipe pile guiding and positioning frame generally can only achieve the vertical accuracy of a single pile L / 100 to L / 200, and the relative position accuracy of the piles is difficult to guarantee, which cannot meet the construction process requirements of the prefabricated cap pier body. Contents of the invention [0003] The object of the present invention is to provide a tool-type guided pile sinking device capable of realizing precise g...
