Problems solved by technology

The steel pipe piles are connected by hinged tie rods, which have the following defects: 1. The hinged tie rods cannot correct the construction deviation of the steel pipe piles; 2. The load generated when the platform is walking or operating acts on different positions The size of the steel pipe piles is inconsistent, and the overall stability of the structure is not high; 3. The hinged connection rods have limited support and strengthening and stability for the steel pipe piles

Abstract

The invention discloses an inclined pile construction system based on a pile top pushing platform. The inclined pile construction system comprises a plurality of steel pipe piles, and the upper ends of the steel pipe piles are connected with pile top positioning pushing devices. The upper ends of the pile top positioning pushing devices are connected with a bearing work platform, and a guiding frame is disposed on the end portion of the bearing work platform. Horizontally arranged and axially retractable connecting rod assemblies are disposed between every two adjacent steel pipe piles. The inclined pile construction system is simple in structure and convenient to use, and can correct construction errors of the steel pipe piles within a certain range by directly arranging the axially retractable connecting rod assemblies at the piled steel pipe piles; and meanwhile, loads generated by walking or operation of the platform can be separated into more steel pipe piles by the connecting rodassemblies, the load of the single steel pipe pile is reduced, and the operating stability of the platform on the steel pipe piles is improved.

Description

technical field [0001] The invention relates to an inclined pile construction system, which belongs to the pile foundation construction technology, in particular to an inclined pile construction system based on a pile top pushing platform. Background technique [0002] At present, the construction of the pile top pushing platform is used for the straight pile foundation, and the connection mode between the platform and the vertical steel pipe pile, and between the steel pipe pile and the steel pipe pile is: the pile top positioning is used between the platform and the steel pipe pile Pushing device, the pile top positioning pushing device is set on the top of the steel pipe pile (see Chinese invention patent CN105442517A for the specific structure of the pile top positioning device). The steel pipe piles are connected by hinged tie rods, which have the following defects: 1. The hinged tie rods cannot correct the construction deviation of the steel pipe piles; 2. The load gen...
