Abstract: Disclosed are a shield tunnel segment structure and a construction method thereof. The shield tunnel segment structure includes segment blocks sequentially spliced in a circumferential direction. Each segment block forms a closed annular segment structure, and outer diameters of adjacent annular segment structures gradually increase in an axial direction. At least two adjacent segment blocks of the same annular segment structure form an annular inner groove, and at least one segment block of the adjacent annular segment structures is provided with an inner bump which matches the annular inner groove. At least two adjacent segment blocks of the same annular segment structure form an annular outer groove, and at least one segment block of the adjacent annular segment structures is provided with an outer bump which matches the annular outer groove. The annular outer grooves and the annular inner grooves are staggered in the circumferential direction.

Abstract: Aqueous dispersions and uses for the same. The aqueous dispersion includes a component (a) of one or more ethylene-vinyl ester copolymers, a component (b) of one or more protective colloids, a component (el) of one or more nonionic surfactants, and a component (d) of one or more dispersants, selected from polycarboxylates. Where an amount of the component (b) and the component (c1) is less than or equal to 3.4 pphm, preferably between 1-3.4 pphm, more preferably between 2-3.1 pphm. Where the weight ratio of an amount of the component (b) to the component (el) is between 1.01-2 and an amount of the component (d) is less than or equal to 1 pphm. The component (b) is polyvinyl alcohol (PVOH).

Abstract: The present application relates to a curtain rod hanging structure, which includes a vertical rod and a hook body, the hook body is provided on the vertical rod, an installation groove is provided on the inner wall of the hook body, and an adjusting pad is detachably arranged in the installation groove and the adjusting pad is configured to hang the curtain rod. The present application realizes hanging curtain rods with different diameters by replacing the adjusting pad in the installation groove, eliminating the need of replacing the overall curtain rod hanging structure and providing the effect of facilitating the installation and high applicability.

Abstract: The present application provides a full light-shading curtain rod including a curtain hanging rod, an end of the curtain hanging rod is provided with a corner structure, and the corner structure is configured for guiding a curtain hung on the curtain hanging rod to turn. It further includes a screen curtain hanging rod, and the screen curtain hanging rod is mounted at a side of the curtain hanging rod facing a wall foundation. An end of the corner structure is detachably connected with a mounting disc, and the corner structure and the mounting disc form a mounting assembly for mounting the curtain hanging rod on the wall foundation. An end of the screen curtain hanging rod is provided with a connecting bracket, and the connecting bracket is connected with the mounting assembly.

Abstract: A bracket includes a base for external connection and a hooking part connected with the base, a bending portion of the hooking part forms a groove, a groove wall connected the groove with the base is provided with a mounting hole, the mounting hole is provided with a damping element, and a damping portion of the damping element is located in the groove.

Abstract: The present application relates to a grooved bracket, which includes a base body for external connection and a first hook part connected to the base body, the bent part of the first hook part forms a trench groove, the inner wall of the trench groove is provided with an embedded groove along the bent path of the first hook part, an embedded body is embedded in the embedded groove, and part of the embedded body exceeds the embedded groove and falls into the range of the trench groove. The present application has the effect that the rod is easy to install and not easy to fall off.
