Embodiment

[0065] The order of setting up is to set up in four areas when setting up, step 100, set up a triangular area, then step 200, set up a channel, then step 300, set up a main chord suspension frame, and then step 500, set up an internal two-step frame (upper layer two Step frame and lower floor two-step frame), last step 600, set up protective railing and foot guard.

[0066] Step 100, setting up the triangular area also includes the following steps:

[0067] Step 101. First, erect the first layer of load-bearing steel pipes above the main chord pipe and the horizontal pipes, erect the first 6m load-bearing steel pipes starting from the horizontal pipes, and then erect three 6m steel pipes at intervals of 400mm from left to right along the direction of the horizontal pipes. Load-bearing steel pipes, 2 4.5m load-bearing steel pipes, 2 3.6m load-bearing steel pipes, 1 3m load-bearing steel pipes, 1 2.5m load-bearing steel pipes, 2 1.2m load-bearing steel pipes, 2 2.5m load-bearing...

Abstract

The invention discloses a building method for a scaffold used for drilling platform pile leg splicing. The building method for the scaffold used for drilling platform pile leg splicing includes the steps that a triangular region of drilling platform pile legs is built; a passage for the drilling platform pile legs is built; a main chord cantilevered frame of the drilling platform pile legs is built; an inner two-step frame of the drilling platform pile legs is built and is divided into an upper layer two-step frame and a lower layer two-step frame; protective railings and foot stopping plates of the drilling platform pile legs are built. The building method for the scaffold used for drilling platform pile leg splicing is high in safety and low in cost and saves time and labor, and the scaffold is easy to build.

Description

technical field [0001] The invention relates to the field of scaffolding, in particular to a method for erecting a scaffold for drilling platform pile legs. Background technique [0002] The pile leg is one of the key components of the jack-up drilling platform. The pile leg of the jack-up drilling platform is generally a triangular truss type, and the highest point of the pile leg is about 170 meters. For hoisting, a single pile leg must be divided into several sections according to the lifting capacity and other factors for hoisting, and the piles shall be connected at high altitude. Connection. The leg material, especially the rack material, is ultra-thick ultra-high-strength steel. It is difficult to weld and install, and it is prone to cracks and deformation. The requirements are high. The legs need to cooperate with the lifting mechanism and locking device, which requires high precision. The legs are the most important and most difficult structure of the platform. Th...
