Example Embodiment
[0044] Example 1
[0045] The invention provides a lattice type composite wellbore structure, specifically as follows Figure 1 to Figure 6 As shown, it includes an outer wellbore and an inner wellbore 1, the number of the outer wellbore is multiple, and the plurality of outer wellbores are connected in sequence from top to bottom. 1 is arranged in the outer wellbore and the outer wall and the inner wall of the outer wellbore are integrated by concrete; in this embodiment, the outer wellbore is prefabricated on a non-construction site, and after the prefabrication is completed, it is directly pulled to the construction site for hoisting, and the inner wellbore 1 is on the construction site. The construction is completed directly after hoisting the outer side of the outer shaft.
[0046] Specifically, the outer wellbore is composed of at least two first barrel walls 3 and two second barrel walls 4, and the first barrel walls 3 and the second barrel walls 4 are arranged at inte...
Example Embodiment
[0066] Example 2
[0067] like Figure 7 to Figure 9 As shown, in order to reduce the difficulty of hoisting, in this embodiment, at least four steel lattice columns 12 on the top and bottom of each outer wellbore extend outward to form the plug-in ends 14, and also include a plurality of crown beams 16, crown The top and bottom surfaces of the beam 16 are provided with at least four mounting holes 17 that are matched with the plug-in ends 14, and a crown beam 16 is provided between the upper and lower adjacent two outer wellbores. The end 14 and the mounting hole 17 are connected to the crown beam 16 , and the rest of the structure is the same as that of Embodiment 1, and will not be repeated here. The height of the crown beam 16 is lower than the height of the outer wellbore. During the hoisting process, the plug end 14 and the installation hole 17 are easier to quickly and accurately locate and plug each other, which improves the hoisting efficiency. At the same time, the ...
