The invention relates to a circular
water delivery tunnel wall window-by-window layered pouring
system and a construction method. The circular
water delivery tunnel wall window-by-window layered pouring
system and the construction method are mainly suitable for circular
water delivery tunnel wall pouring construction. The layered pouring
system is composed of a main hopper, a main flow dividing
pipe, a second-level hopper, a secondary flow dividing
pipe, a third-level hopper, an upper grouting
pipe, a flow dividing string
barrel, a middle grouting pipe and a lower grouting pipe. The construction method mainly comprises the construction steps of construction preparation, needle beam formwork system installation, trolley walking, layered pouring system installation,
flange plate and groutingassembly installation, camera installation, tunnel side wall concrete pouring, tunnel vault concrete pouring, grouting system dismounting, demolding and lining maintenance. According to the circularwater delivery tunnel wall window-by-window layered pouring system and the construction method, lining side wall concrete enters a mold layer by layer and window by window, the defects of concrete segregation, aggregate accumulation, herringbone slope cold joints and the like are effectively avoided, the entity quality and the appearance quality of lining side wall concrete pouring are improved, the side wall pouring pipe replacing procedure is reduced, the labor intensity is lowered, and the pouring time is saved.
