庶聲shù — the common many; gives the sound
IFT庶 shù → 遮 zhē — the retroflex onset shifts sh- to zh- within its family, and the final opens
A step (辶) plus 庶 (shù) for the sound — 說文 reads it 遏, to bar. To move across and stand in the way is to block, to cover: 遮蔽, 遮擋; to put up between the sun and yourself is 遮陽. The onset slid from shù to zhē.
