Embodiment Construction

[0032] see figure 1 , the present invention provides a steel pipe concrete mixed pile foundation. The steel pipe concrete mixed pile foundation includes a steel pipe concrete structural pile and a reinforced concrete structural pile; the steel pipe concrete structural pile and the reinforced concrete structural pile are sequentially connected from top to bottom to form an integral pile foundation; The concrete-filled steel pipe structural pile is placed above the zero point of the bending moment of the overall pile foundation; the reinforced concrete structural pile is placed below the zero point of the bending moment of the overall pile foundation; label.

[0033] in:

[0034] The concrete-filled steel pipe structure pile includes equal-diameter steel pipes 1, reduced-diameter steel pipes 2, and diameter-increased steel pipes 3; the equal-diameter steel pipes 1 are connected with the diameter-increased steel pipes 3 through the reduced-diameter steel pipes 2 to form an overa...

Abstract

The invention belongs to the technical field of bridge pile foundation engineering and relates to a concrete filled steel tube composite pile foundation and a construction method. The concrete filledsteel tube composite pile foundation comprises a concrete filled steel tube structural pile and a reinforced concrete structural pile. The concrete filled steel tube structural pile and the reinforcedconcrete structural pile are connected from top to bottom in sequence to form an integral pile foundation. The concrete filled steel tube structural pile is located above the zero point of the bending moment of the integral pile foundation. The reinforced concrete structural pile is located below the zero point of the bending moment of the integral pile foundation. The mark of concrete filled upin the reinforced concrete structural pile is lower than that of concrete filled up in the integral pile foundation. The concrete filled steel tube composite pile foundation and the construction method provided by the invention have the advantages that construction is convenient, the anti-seismic performance is good, the bearing capacity is high, and the construction difficulty and the construction cost can be lowered.

Description

technical field [0001] The invention belongs to the technical field of bridge pile foundation engineering, and relates to a steel pipe concrete mixed pile foundation and a construction method, in particular to a mixed structure pile foundation in which a steel pipe concrete member and a reinforced concrete member are combined to be stressed together and a construction method thereof. Background technique [0002] In areas with high seismic fortification intensity, especially in bridge projects with deep water, large scour hydrological conditions and weak stratum geological conditions, pile foundations, as an important part of bridge engineering, have extremely high requirements for seismic performance. The superstructure loads are efficiently transferred to the foundation and also resist the horizontal loads caused by earthquakes. The pile foundation is located underwater or underground, and it is extremely difficult to repair once it is damaged. [0003] At present, bridge...
