Problems solved by technology

At present, in the field of construction engineering, in order to meet the requirements of compression resistance, pullout resistance, and thrust resistance, the general situation is to increase the length and diameter of the pile foundation to improve the pile foundation through a larger area and larger diameter. The overall strength and bearing capacity of the pile foundation will undoubtedly increase the workload and reduce the work efficiency, especially the substantial increase of the project cost.

Abstract

The invention provides a diameter-varied composite pile. The diameter-varied composite pile is characterized in that a diameter-varied pile body with increasing length and decreasing diameter from top to bottom is formed by 2 to 3 steel rebar concrete pile bodies; on the basis of the diameter-varied pile body, the periphery or the pile body of the diameter-varied pile body is formed in one of the following way or in the following combined ways of: (1) adding a group of cement soil piles around the diameter-varied pile body, (2) adding a carrier at the bottom end of the diameter-varied pile body and (3) adding a pulling-resistant carrier at the bottom end of the diameter-varied pile body. According to the diameter-varied composite pile, the crushing-resistant capacity, the pulling-resistant capacity, the bending-resistant capacity and shearing-resistant capacity are very strong and at the same time the building materials can be saved and the cost can be lowered; moreover, various combination ways are provided to meet different requirements of design and geology, so that the range of application is wide.

Description

technical field [0001] The application relates to the field of civil engineering, in particular to a variable-diameter composite pile. Background technique [0002] With the rapid development of science and technology in the field of construction, the requirements for the structure and foundation of buildings are getting higher and higher, coupled with the complexity of geological conditions, so more comprehensive, stronger and higher requirements are put forward for pile foundations, such as In addition to the designed vertical bearing capacity, the pile foundation is also required to have certain pullout resistance and horizontal thrust resistance. At present, in the field of construction engineering, in order to meet the requirements of compression resistance, pullout resistance, and thrust resistance, the general situation is to increase the length and diameter of the pile foundation to improve the pile foundation through a larger area and larger diameter. The overall s...
