Summary:The invention belongs to the field of tunnel engineering secondary linings, and particularly relates to a tunnel secondary lining width adjustable concrete end mold and an adjusting method thereof. The end mold comprises an inner side end mold and an outer side end mold which are mutually hinged, the inner side end mold is connected to a trolley mold, the outer side end mold is slidably connected to an extending plate, and the relative sliding direction is in the radius direction of the outer side end mold fan shape. Aiming at the problem in the prior art that a steel end mold cannot extend randomly to fix a back adhered water stop belt, as a result, the water stop belt cannot exert the effect of stopping water, the width of the end mold can be adjusted according to the width between a trolley mold and a primary support surface to effectively fix the back adhered water stop belt, and a required waterproof effect is achieved. Compared with the prior art, the problem of fixing the back adhered water stop belt i
