Embodiment 1

[0036] see Figure 1-5 , a kind of floating drilling platform, it includes the semi-storage barges 1 that are interconnected with each other by connecting cross-links 2, the interior of the cabin of the semi-storage barges 1 is provided with a load-bearing distribution beam 4, and the top of the load-bearing distribution beam 4 A platform surface 10 is provided; a crawler crane 3 is provided on the top of one of the semi-storage barges 1 , and a drilling rig 9 for drilling is provided on the platform surface 10 at the top of the other half-storage barge 1 . By adopting the above-mentioned floating drilling platform, the fast moving and positioning of the floating drilling platform can be realized, and the drilling operation efficiency of the platform can be improved.

[0037] Further, a counterweight 5 for maintaining the balance of the half-storage barge 1 is placed on the half-storage barge 1 . The level of the two half-storage barges 1 can be adjusted through the counterwe...

Embodiment 2

[0046] Adopt the construction method of the floating drilling platform described in any one of claims 1-9, it is characterized in that it comprises the following steps:

[0047] Step1: Connect the bow and stern of the two semi-storage barges 1 into a whole using the connecting system horizontal link 2, and the section steel of the connecting system horizontal link 2 is welded firmly with the keel of the semi-storage barge 1;

[0048] Step2: Install a crawler crane 3 on one of the semi-storage barges 1. The crawler crane 3 is laid with section steel and steel plate, and the crawler is fixed with the limit device 8, which is firmly connected with the cabin keel;

[0049] Step3: The other half of the barge 1 uses the counterweight 5 to level the platform, uses the Bailey beam base 11 to level the platform surface 10, and assembles Bailey beams on the Bailey beam base 11 to form a load-bearing distribution beam 4. Lay horizontal distribution beam steel and steel panels to form the...

Abstract

The invention provides a floating drilling platform and a construction method thereof. The floating boring platform comprises half-cabin barges interlinked by a coupling link, a load-bearing distribution beams are arranged in cabins of the half-cabin barges, and a platform layer is arranged at the top of each of the load-bearing distribution beams; a crawler crane is arranged at the top of one ofthe half-cabin barges while a drilling rig used for drilling is arranged on the platform layer of the top of the other half-cabin barge. By the arrangement, actual problems about an existing drillingmachine in great limitation of geographical conditions, difficult anchor positioning, requirement for additional heavy lifting equipment, high barge moving cost, failure in positioning and pile inserting of steel casing during drilling construction and the like can be effectively solved.

Description

technical field [0001] The invention belongs to the technical field of bridge construction, in particular to a floating drilling platform and a construction method. Background technique [0002] In the construction of bored pile foundation in bridge water, the drilling platform must be set. At present, the construction platform of deep-water bridge pile foundation mainly includes four types: steel pipe pile support platform, steel casing support platform, steel cofferdam support platform and floating platform; the construction foundation scheme of floating platform is a relatively mature scheme, and now Most of the traditional floating platform construction schemes used are large-scale barges as the carrier, and longitudinal beams and gantry running systems are assembled on the barges. However, in the process of actual use, the construction foundation of the above-mentioned traditional floating platform has the disadvantage of being greatly restricted by geographical condit...
