PURPOSE:To relieve the burden of a pouring work, by a method wherein a shutter or a guide port with a valve, which is connectable to a concrete feed pipe, is formed in the vicinity of the base of forms installed in water. CONSTITUTION:A shutter or a guide port 1 with a valve, which is connectable to a concrete feed pipe H, is formed in the vicinity of the base of forms M in water W, and a feed pipe H, connected to a concrete pump, is connected to the guide port 1. With a valve opened, concrete is pressed in, and water in the forms M is pushed up, in order, from the lower part to the upper part by means of poured concrete. Water in the forms M is drained from the upper part of the forms M, and after the interior of the forms M is full of concrete, the valve is closed and the feed pipe H is disconnected. This, since the end of the feed pipe H is secured to the forms M, eliminates a fear of the end of the feed pipe H being moved through a reaction force generated during press-in of the concrete, and permits a decrease in the burden of a concrete pouring work. |
