The utility model discloses a sunshade for urban subway construction. The sunshade comprises a support skeleton formed by multiple steel pipes in an intercrossed welded manner. A protective panel is riveted to the support skeleton. Telescoping support rod pieces supporting the support skeleton are movably connected with four corners of the support skeleton. Each of the telescoping support rod pieces comprises an inner sleeve, an outer sleeve and an adjusting inserting pin. Multiple through adjusting holes are axially arranged in the inner sleeve at intervals. A through fixed hole is arranged in the outer sleeve. The adjusting inserting pins penetrate the fixed hole and the adjusting holes so as to fixedly connect the outer sleeve and the inner sleeve. Via the arrangement of the telescoping support rods, the height of the whole sunshade is adjustable so as to met construction environment requirements. While the original sun and rain shading function is ensured, novel, attractive and practical effects are achieved, and the sunshade coordinates with the surrounding environment of a construction plant. The supervision departments and owners highly appraise the sunshade, and better social benefit is gained.
