Abstract
The invention relates to a method for constructing an end wall of a subway station in a sandy gravel stratum. The method comprises the following steps of dividing the end wall into an inner layer andan outer layer, performing casting three times, firstly casting the inner layer of the end wall, providing a stable working surface for shed pipe construction, then casting the outer layer of the endwall, reinforcing the inner layer of the end wall by a pre-casting strip, constructing a pipe shed on the inner layer of the end wall, performing lap jointing of tight waterproof coiled materials, andfinally pouring a post-cast strip of the outer layer of the end wall outside a shed pipe construction area. The waterproof performance of the end wall waterproof coiled material can be guaranteed, and therefore the safety of a foundation pit is guaranteed.
