The present invention relates to a method for manufacturing a concrete block, comprising the steps of: measuring the planned alignment considering the horizontal alignment, slope and cant of a site on which railway tracks are to be laid; arranging a plurality of first temporary assembly supports corresponding to the measured horizontal alignment; installing first temporary rails on the first temporary assembly supports, and adjusting the slope and cant in between the first temporary rails to correspond to the measured slope and cant; installing a plurality of first molds on the first temporary rails, following along therewith, so that the slope and cant correspond to the measured slope and cant; installing a pair of second molds along the longitudinal direction of the first temporary rails, thereby closing off the upper lateral sides of the first molds; arranging, to the horizontal alignment, a plurality of second temporary assembly supports corresponding to the first temporary assembly supports, on the outer sides of the first temporary assembly supports; installing second temporary rails on the second temporary assembly supports so that a vertical alignment correspond to the vertical alignment of the on-site roadbed; pouring concrete; forming the concrete surface with a finisher moving along the second temporary rails; curing the concrete; and separating the cured concrete from the first and second molds, and subsequently turning the concrete over.

The invention discloses a horizontal seam U-shaped closed rib junction structure of an assembled shear wall structure, comprising an upper-layer outer wall prefabricated shear wallboard (1), a lower-layer outer wall prefabricated shear wallboard (2), an upper-layer inner wall prefabricated shear wallboard (16), a lower-layer inner wall prefabricated shear wallboard (17), U-shaped closed ribs (5),a horizontal reinforcing rib (6) and filled cast-in-place concrete (13), wherein the U-shaped closed ribs adopting the upper-layer outer wall prefabricated shear wallboard, the lower-layer outer wallprefabricated shear wallboard, the upper-layer inner wall prefabricated shear wallboard and the lower-layer inner wall prefabricated shear wallboard are staggered and are in lap joint to form an annular ring; the horizontal reinforcing rib is arranged in the annular ring to reliably connect the vertical reinforcing steel bars of the assembled shear wall; and the filled cast-in-place concrete of ahorizontal seam (7) realizes the purpose that the resistance to shear of the horizontal seam is equivalent to the cast-in-place concrete shear wall. The whole prefabricated assembled shear wall can be reliably connected with the shear wall and a floorslab, the whole prefabricated assembled shear wall performance can be ensured, and the horizontal seam U-shaped closed rib junction structure has the advantages of simple form and material conservation and is convenient to construct.

The invention discloses a combined type protection shed frame and a construction method thereof. The combined type protection shed frame is characterized in that a bearing structure located on the top surface of a bridge is arranged; the top surface of the bridge is taken as a bearing foundation by bearing longitudinal girders in the bearing structure; bearing cross girders crossing over the bridge are supported by the bearing longitudinal girders; a steel-structure frame located at the bottom part of the bridge is arranged; frame longitudinal girders in the steel-structure frame are suspended below the bearing cross girders through suspenders, and are located at both sides of the bridge; and frame cross girders in the steel-structure frame are suspended at the bottom parts of the frame longitudinal girders. The combined structure of the combined type protection shed frame disclosed by the invention is entirely borne on a bridge deck, and foundations do not need to be constructed at both sides of the existing railroad line, thereby, the on-site construction quantity of the existing railroad line is greatly reduced, the construction risk is lowered, the potential safety hazards areeliminated, and the interference on the normal operation of the existing railroad line is effectively reduced.
