Steel pipe pile guiding frame structure and construction method

Abstract

The invention discloses a steel pipe pile guide frame structure and a construction method. The steel pipe pile guide frame structure is used for guiding in the installation process of a steel pipe pile of a trestle and comprises two sets of supporting beams, at least one transverse beam, at least two pairs of guiding frames and a pair of supporting legs; the supporting beams are longitudinally arranged along the trestle; the transverse beams are transversely fixed to the top surfaces of the supporting beams along the trestle to form an integrated structure; each pair of guiding frames are oppositely arranged on the supporting beams for guiding in the process of lowering the steel pipe pile; the supporting legs are symmetrically arranged on the bottom surfaces of the supporting beams and supported on a trestle main transverse beam constructed in the foremost portion; the height of each pair of supporting legs can be adjusted, wherein the rear end of the integrated structure in the longitudinal direction of the trestle is hinged to two Bailey truss sets at the rear side of the trestle main transverse beam, and the integrated structure can be horizontal by adjusting the height of thesupporting legs. The steel pipe pile guide frame structure has the advantages of being suitable for long-period strong surge conditions without outside sea protection and the like, and can be widely applied to the technical field of water transportation engineering construction.

Description

technical field [0001] The invention relates to the technical field of water transport engineering construction. More specifically, the present invention relates to a steel pipe pile guide frame structure and construction method. Background technique [0002] During the piling operation of steel pipe piles, in order to ensure the coordinates and verticality of the pile body, it is necessary to set up a guide frame to limit the position of the steel pipe piles. And simple mobile three. The self-contained guide frame of the piling ship inserts and drives steel pipe piles by fixing it with the hull of the piling ship. Independent steel pipe piles form a frame for piling. The disadvantage of the guide frame of the piling ship is that, since it is integrated with the hull, it is easily affected by wind, waves and water depth, and the construction accuracy is difficult to guarantee, and it is not suitable for construction in shallow water or reef waters. The disadvantage of th...

Problems solved by technology

The disadvantage of the guide frame of the piling ship is that it is easily affected by wind, waves and water depth because it is integrated with the hull, and the construction accuracy is difficult to guarantee, and it is not suitable for construction in shallow water or reef waters

The disadvantage of the assembled guide frame is that because the tripod is fixed on one side of the piling platform with bolts, the platform is prone to linkage during piling, and the construction accuracy and the stability of the piling platform will be affected.

The disadvantage of the simple mobile guide frame is that additional auxiliary piles need to be installed, and the work efficiency is relatively low

[0003] The total length of the steel trestle bridge at CLP Hub Wharf in Pakistan is 1600m, the bridge width is 8m, and the total number of steel pipe piles reaches 600. The construction sea area has no soft covering layer, and the seabed is covered with uneven reefs. The hoisting of lifting equipment and the construction of steel pipe pile foundations have a great influence, and it is difficult to guarantee the verticality of pile foundations
