Specifically, the first tube 211 has a diameter of 620/600mm, a length of 7625mm, and eight tubes 210 each have a diameter of 640/620/600mm. It should be noted that the through and the opposite insertion of the four-way tube 210 and the first tube 211 are internally knotted to form glue, the hand is pasted on the outside, the width of the hand pasted cloth is 330mm, and the thickness is 10mm.
After the eight first pipe bodies 211 are connected together through the four-way pipes 210, the pipeline of the middle part 21 is continuously built, one end of each first pipe body 211, which is far away from the four-way pipe 210, is connected with a second pipe body 212 through a first sleeve pipe 213, and the second pipe body 212 is connected with the frame part 22, so that the middle part 21 is in a cross structure; the number of the second tubes 212 is eight, the diameter is 620/600mm, and the length is 7992mm. The first ferrule 213 is eight in number, 640/620mm in diameter and 1560mm in length.

Wherein each node needs to draw a diagonal to determine its relative position. The horizontal plane reference is based on the center. The raw material pipe fittings are marked with serial numbers, and the size of each pipe is corresponding to the size of the pipe. Because the pipeline is a winding process, the pipeline has large and small diameters, and the center of the pipeline is used as the standard when the elevation is measured. When the pipelines are hand-pasted, the diameters of two ends of a joint are processed to be the same, and then hand-pasting is carried out, wherein the width of the hand-pasting is not less than 15cm, the hand-pasting thickness between large pipelines is 10mm, and the hand-pasting thickness is 5mm when small pipelines exist.
After the floating pipe of the middle layer 52 is built, the annular base 40 is installed, the annular base 40 comprises a circular pipe 41, installation stand pipes 42 and reinforcing ribs 43, the circular pipe 41 is connected to the floating pipe of the middle layer 52 through a plurality of installation stand pipes 42, the reinforcing ribs 43 are distributed on the circular pipe 41 in a criss-cross mode to form an installation platform for connecting the bait bin 50, wherein saddle mouths at two ends of the installation stand pipes 42 can be cut and ground at an assembly site.
After the annular base 40 is installed, installation of the primary conduits of the walkway layer 30 may then be performed. Wherein the walkway layer 30 is connected to the floating pipe of the middle layer 52 through a plurality of upper pillars 31. The number of the upper columns 31 is one hundred and ninety, both ends of the upper columns 31 are saddle-mouth shaped, one end of each upper column 31 is connected with a large pipe with the diameter of 620mm of the floating pipe of the middle layer 52, namely, one end of the upper column 31 is connected on the first pipe body 211, the second pipe body 212, the third pipe body 2210 and the fourth pipe body 2220, the other end faces upwards to be used for being connected with the pipeline of the pavement layer 30, and part of redundant pipeline at the connection part with the annular base 40 needs to be cut off. The upper vertical pipe is positioned importantly, infrared rays are used necessarily, the opening of a saddle opening in the upper opening direction is ensured to be in the center of the pipe, and the next step of installation is difficult. The saddle mouths of the upper columns 31 arranged in a straight line also need to be in the same direction, so a jig is needed during processing, the direction needs to be well controlled, and the installation is extremely difficult. When the upper vertical pipe is installed, part of the upper vertical pipe can be fixed firstly, and the custom problem of an installer is mainly seen.
The pavement layer 30 comprises an outer frame 32 and an inner frame 33, and the inner frame 33 is connected to the inner side of the outer frame 32 through a second short pipe; wherein, the total length of the outer frame 32 is 36m, and comprises four side pipes which are sequentially connected end to end, each side pipe comprises four step pipes which are sequentially connected, the outer frame is formed by splicing sixteen step pipes, and the bend angle is directly connected by cutting at 45 degrees; interior frame 33 is including a plurality of sidelines of end-to-end connection in order and connect in the connecting pipe of the inboard of a plurality of sidelines in crisscross form, and the quantity of sideline is eight, and the quantity of connecting pipe is twelve. The number of the second short pipes in the step layer 30 is more, and the number of the second short pipes is one hundred and ninety two, so that the workload of hand pasting is extremely large, omission is avoided, and material reduction by stealing work is avoided. After the middle and upper layers are installed, the middle and upper layer components are lifted upwards by 2000mm by using two cranes, twelve portal frames are arranged below the middle and upper layer components, and the heights of the portal frames are determined to be on the same level by using an infrared level meter. Note that: the portal frame is formed by welding at least more than 14# channel steel, and the ground for placing the portal frame needs to be firm. The safety measures must be perfected during the lifting process. The hoisting must be done with the crane, can not be drawn with the calabash, because the calabash tonnage is not enough, and a plurality of calabash atress can not calculate, easily the incident appears. The portal frame is balanced as much as possible and cannot deviate too much. After the portal frame is finished, steel pipe frames are required to be built at the four corners and the cross joint (the middle position of each side) for reinforcement, and the construction of the steel pipe frames does not influence the bottom construction as much as possible. The center positions of the lifted middle layers are on the same horizontal plane, and the difference cannot exceed 5mm. The portal frame can not be positioned at the hand-pasted position and can be staggered as much as possible. The middle and upper layers are limited horizontally on the portal frame to prevent the displacement of strong wind. The lower part of the portal frame must be fixed to prevent collision and collapse.
And then a lower-layer buoy 10 can be installed, wherein the lower-layer buoy 10 comprises a bottom layer outer frame 11 and a bottom layer middle straight pipe 12, the bottom layer outer frame 11 is approximately rectangular, the bottom layer middle straight pipe 12 is connected to the inner side of the bottom layer outer frame 11, and two ends of the bottom layer middle straight pipe are respectively connected with two opposite sides of the bottom layer outer frame 11.
