Problems solved by technology

However, in the process of actual use, the above-mentioned traditional floating platform construction foundation has defects that are greatly restricted by geographical conditions. When water transportation such as reservoir areas and dam areas is underdeveloped, and large barges cannot enter, this floating platform construction plan cannot be used. Meet construction requirements

Abstract

The invention discloses a floating drilling platform used for bridge construction and a construction technology thereof. The floating drilling platform comprises a floating supporting platform, a temporary fixing device used for temporarily fixing the floating supporting platform, and a hoisting system distributed on the floating supporting platform; the floating supporting platform comprises horizontal floating bodies, a horizontal supporting framework and horizontal steel plates, wherein the horizontal floating bodies are formed by assembling a plurality of small floating boxes; lowering through holes used for lowering steel casings are arranged on the horizontal steel plates; and the lowering passages are correspondingly reserved on the horizontal supporting framework and the horizontal floating bodies. The construction technology of the floating drilling platform comprises the steps of: firstly, assembling the floating supporting platform; secondly, shifting the floating supporting platform; thirdly, temporarily fixing the floating supporting platform; fourthly, lowering the steel casings; fifthly, constructing drilling piles; and sixthly, constructing base slabs in water. The floating drilling platform and the construction technology disclosed by the invention have the advantages of reasonable design, convenience for construction, low construction cost, good using effect, and capability of solving the problems of large restriction of geographical conditions, incapability of driving drilling pile foundations, incapability of positioning and inserting-piling the steel casings and the like of the traditional floating platform.

Description

technical field [0001] The invention belongs to the technical field of bridge construction, and in particular relates to a floating drilling platform for bridge construction and a construction process thereof. Background technique [0002] The main bridge of Qujiang Extra Large Bridge is (48+4×80+48)m prestressed concrete rigid frame continuous beam, and the main pier foundation piers of the prestressed concrete rigid frame continuous beam along the bridge direction are 28# pier to 34# pier #pier, of which 28# pier and 34# pier are separation piers, and the 5 main piers of 29# pier to 33# pier are all located in the river water of the canal (that is, piers in the water), and are designed as high pile caps. During the actual construction, the height of the caps of the 5 main piers from Pier 29# to Pier 33# is 5.0m, and the height of the added platform is 2m, and the plane size of the cap is 26m×19.6m, and the plane size of the added platform is 14.2×12.2m. The height of the ...
