Title:
METHOD FOR DISCHARGING WATER FROM DAM CONCRETE PLACING AREA VIA CONCEALED PIPE
Document Type and Number:
WIPO Patent Application WO/2012/163266
Kind Code:
A1
Abstract:
A method for discharging water from a dam concrete placing area via a concealed pipe, comprising: arranging a primary water discharge pipe in a predetermined area to communicate the upstream and the downstream of the dam; laying secondary pipes for water discharge from the main water discharge pipe to the left side and the right side of the dam body to communicate with each dam block in the area; and connecting vertical tertiary pipes for water discharge from the secondary water discharge pipes on each dam block to communicate with each concrete placing space in the dam block. By adopting the method for discharging water from the dam concrete placing area via the concealed pipe, during the concrete pouring construction process of the dam, the embedded water discharge pipe network extends and expands to all poured concrete dam blocks with the progression of the dam body concrete pouring, thereby completely covering each new concrete pouring space within the dam area, solving the problem of large-area water deposit on the dam concrete placing area, creating a dry construction environment for concrete pouring, ensuring concrete pouring quality, reducing construction interference, and achieving civilized construction.
