Problems solved by technology
[0003] The technical problem to be solved by the present invention is: the spud legs and spud cans of the existing drilling platform are closed by adopting the method of fixing the spud legs, horizontal support pipes, inclined support pipes and other components to the spud cans in sequence. It is long, and once the spud legs are welded to the spud cans, it is inconvenient to check the welding condition of the spud legs. A method for closing the spud legs and the spud cans of the drilling platform is provided.

[0030] Please combine Figure 1-2 It should be understood that a method for closing a drilling platform leg and a spud can comprises the following steps:
[0031] S0: fix the bracket 10 to the spud shoe;
[0032] S1: Divide a cutting area on the side of the bracket 10 close to the leg. Select the side of the bracket 10 close to the leg for the cutting area;
[0033] S2: Cut the cutting area to obtain a first bracket segment 11 for connecting with the pile leg, the remaining part after cutting the bracket 10 is the second segment 12 of the bracket, the first segment 11 of the bracket is connected with the bracket leg The second plate segment 12 can be assembled into a complete bracket 10;
[0034] S3: welding the first segment 11 of the bracket to the bottom of the leg;
[0035] S4: fixing the bottoms of the legs together through several horizontal support pipes;
[0036] S5: Fix the bottoms of the legs together through a number of inclined support pipes to obtain a whole ...

The invention discloses a folding method of pile legs and pile shoes of a drilling platform. The folding method comprises the following steps that firstly, the sides, close to the pile legs, of toggle plates are divided into a cutting area; secondly, the cutting area is cut to obtain first toggle plate segments used for being connected with the pile legs, the residual parts obtained after toggle plate cutting are divided into second toggle plate segments, and the first toggle plate segments and the second toggle plate segments can be spliced to form the integral toggle plates; thirdly, the first toggle plate segments are welded to the bottoms of the pile legs; fourthly, the bottoms of the pile legs are fixed together through a plurality of horizontal supporting pipes; fifthly, the bottoms of the pile legs are fixed together through a plurality of inclined supporting pipes, and a pile leg integral piece is obtained; sixthly, the pile leg integral piece is hoisted, and the first toggle plate segments on the pile leg integral piece can be matched with the second toggle plate segments on the pile shoes; and seventhly, the first toggle plate segments and the second toggle plate segments are welded and fixed. The folding method has the beneficial effect of saving work hours.
Description
technical field [0001] The invention relates to a method for closing pile legs and spud cans of a drilling platform. Background technique [0002] During the construction of the drilling platform, the pile legs and spud cans are usually connected by brackets, and then the pile legs are fixed together by horizontal support pipes and inclined support pipes. Due to the method of welding each component in sequence, the closing cycle is longer. Contents of the invention [0003] The technical problem to be solved by the present invention is: the spud legs and spud cans of the existing drilling platform are closed by adopting the method of fixing the spud legs, horizontal support pipes, inclined support pipes and other components to the spud cans in sequence. It is relatively long, and once the spud legs are welded to the spud cans, there is a defect that it is inconvenient to check the welding condition of the spud legs. A method for closing the spud legs and the spud cans of ...
