Mudjack pipe frame for steel pipe pile and layout method of mudjack pipe frame

Abstract

The invention discloses a mudjack pipe frame for a steel pipe pile and relates to the field of bridge engineering construction. The mudjack pipe frame comprises a plurality of mudjack pipe frame sections connected with each other, wherein each of the mudjack pipe frame sections comprises a frame body; a plurality of mudjack pipes are arranged on the frame body; a high-pressure hose is arranged between the mudjack pipes of every two adjacent mudjack pipe frame sections and communicates with the mudjack pipes of the two mudjack pipe frame sections; and the frame bodies of the two mudjack pipe frame sections are connected. The mudjack pipe frame is convenient to mount and dismantle, high in construction efficiency, safe and reliable and saves manpower and material resources.

Description

technical field [0001] The invention relates to the field of bridge engineering construction, in particular to a grouting pipe frame for steel pipe piles and a laying method thereof. Background technique [0002] With the development of bridge science and technology and the application of large-scale mechanical equipment in the construction process, steel pipe piles with longer pile lengths, larger pile diameters and shear rings are widely used in bridge structures as a load-bearing pile foundation. middle. In order to give full play to the role of the bearing layer at the tip of the steel pipe inclined pile, it is usually necessary to grout at the bottom of the pipe pile to improve the ultimate bearing capacity of the steel pipe pile. [0003] For the layout of such large-scale steel pipe pile grouting pipe racks with long pile length, large pile diameter and shear force ring, the grouting pipe rack includes the frame body and multiple grouting pipes. For piles, it is nec...

Problems solved by technology

[0003] For the layout of such large-scale steel pipe pile grouting pipe racks with long pile length, large pile diameter and shear ring, the grouting pipe rack includes the frame body and multiple grouting pipes. For piles, it is necessary to lay out grouting pipe racks in sections in steel pipe piles. The segments of traditional grouting pipe racks are connected by full welding. The pipe is welded. This welding method not only makes the installation of the grouting pipe frame troublesome, time-consuming and laborious, but also requires the operator to enter the steel pipe pile to cut the grouting pipe frame when removing the grouting pipe frame. great security risk
