Problems solved by technology

The traditional drilling platform generally adopts the structural form of steel pipe driven piles combined with the connection system. The steel pipe driven piles need to be inserted one by one, and then the connection system between the piles is installed. The construction efficiency is low, and the steel pipe piles are stable in the marine environment. There is a big problem with the stability, prone to inverted piles and misalignment, and the follow-up construction is quite troublesome

Embodiment Construction

[0025] The present invention will be further described in detail below in conjunction with the drawings and embodiments.

[0026] See figure 1 As shown, the present invention provides a self-leveling device 100 for a drilling platform, which includes a casing 1, a supporting pile 2, a distribution beam 3, a connector 4, and an adjustment mechanism 5.

[0027] The casing 1 is a steel casing, and a support 11 is fixed on its outer wall. The support 11 in the present invention is fixed at the top of the casing 1 by welding.

[0028] The supporting pile 2 can move back and forth in the casing 1, and a backing beam 21 is fixed on the outer wall of the supporting pile 2. The backing beam 21 in the present invention is fixed to the end of the supporting pile 2 by welding.

[0029] The pad beam 21 is located between the support 11 and the distribution beam 3, and the support 11, the pad beam 21 and the distribution beam 3 can be detachably connected to the connecting piece 4. The connecting pi...

Abstract

The invention discloses a drilling platform self-leveling device and a construction method thereof, and relates to the field of bridge construction. The drilling platform self-leveling device comprises a casing pipe, a supporting pile, a distributive girder and a connecting part, wherein the supporting pile can reciprocate in the casing pipe, a support is fixed to the outer wall of the casing pipe, a template beam is fixed to the outer wall of the supporting pile and located between the support and the distributive girder, and the support, the template beam and the distributive girder are all detachably connected with the connecting part. The drilling platform self-leveling device further comprises an adjusting mechanism with one end fixed to the supporting pile and the other end fixed to the distributive girder, and the adjusting mechanism can stretch and retract between the supporting pile and the distributive girder. The drilling platform self-leveling device is convenient to mount and capable of improving construction efficiency, and a smooth drilling platform can be established on the sea surface without reference targets.

Description

Technical field [0001] The invention relates to the field of bridge construction, in particular to a construction method for self-leveling and installation of a drilling platform. Background technique [0002] With the development of bridge technology, bridge construction has moved from large rivers to the ocean world. In the face of a complex ocean environment, building a bridge foundation is the key to the success or failure of bridge construction. The traditional drilling platform generally adopts the structural form of steel pipe driven pile combined with connection system. The steel pipe driven pile needs to be inserted one by one, and then the connection system between the piles is installed. Its construction efficiency is low, and the steel pipe pile is stable in the marine environment. There is a big problem in performance, and the phenomenon of falling piles and deviation is easy to occur, and subsequent construction is quite troublesome. The integrally installed drilli...
