The invention discloses a U-shaped steel composite support structure for a deep dynamic pressure soft rock roadway and a construction method of the U-shaped steel composite support structure. The U-shaped steel composite support structure comprises anchor rods, anchor cables, a U-shaped steel support, a uniform pressure relief course, an inverted arch and supporting stand columns. The construction method comprises the steps that firstly, the anchor rods and the anchor cables are driven into surrounding rock; secondly, the U-shaped steel support is erected; and thirdly, the uniform pressure relief layer is arranged between the U-shaped steel support and the roadway surrounding rock, wherein the uniform pressure relief layer comprises a polyester fiber net, filling bodies and a rebar net. If the surround rock where the roadway is located is much broken, the number of surrounding rock grouting equipment can be increased; if a floor heave phenomenon occurs in the roadway, the number of inverted arches can be increased; and if the vault and the two sides of the roadway are intense in ground pressure and deform greatly, the number of supporting stand columns can be increased. The uniform pressure relief layer is additionally arranged on the basis of a common U-shaped steel support structure, the setting load of the support structure is increased through a pressure relief effect of the uniform pressure relief layer, and a high deformation buffering capability is achieved; and meanwhile, a plurality of selectable measures are provided, and the U-shaped steel composite support structure and the construction method thereof can adapt to different stratum conditions, can save the cost, and are remarkable in economic benefit.

Triangulated shells can be free-formed but are uneconomical compared to translational shells that can only be flat. Scale-trans shells are limited in terms of number and arrangement of the openings. The present invention provides a free-formed, custom-tailored shell surface and a regularly shaped, mass-produced shell surface that can be assembled fairly evenly from advantageously quadrangular mesh elements having coplanar node points. The flexibility of a triangle net of shell pieces in a large scale is combined with the evenness of a quad net for meshes in a small scale, whereby triangular meshes at the shared side of adjoining square nets are combined in pairs to give irregular quadrangular meshes having coplanar vertices. The inventive shell is especially suitable for use as an energy-saving building such as a weekend home, emergency shelter, cupola of an observatory, roof of a building or an inner courtyard, as the shell of a large multi-story building or as a sports hall or factory building. It is also suitable as a part of a vault, and as a complex shell consisting of a single continuous surface for exhibition or station buildings. Parts of a Bohemian dome, cushion-roof, Isler shell or blob can be combined within any individual shell.
