Dam concrete cabin surface water accumulation hidden pipe discharge method

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.

Description

technical field [0001] The invention relates to a method for discharging accumulated water, in particular to a method for discharging underground water in the area of ​​a dam concrete warehouse. Background technique [0002] During the construction of a concrete dam project, surface washing, rain, concrete bleeding, etc. will cause the surface of the silo to accumulate water, forming many "puddles" or even "ponds" of different sizes on the silo surface, resulting in the inability to cover the newly poured water in time. Concrete not only affects the construction progress of the project and the quality of concrete pouring, but also affects the civilized construction on site. Therefore, the accumulated water should be drained before concrete pouring. Commonly used methods to remove water in warehouses mainly include: using small submersible pumps to pump water, manually using brooms to sweep, manually scooping water, using cotton yarn or rags to remove water, etc., but these ...

Problems solved by technology

Commonly used methods to remove water in warehouses mainly include: using small submersible pumps to pump water, manually using brooms to sweep, manually scooping water, using cotton yarn or rags to remove water, etc., but these methods are only suitable for dealing with a small area of ​​a single dam block For a dam with a certain scale, due to the large number of dam blocks and the large area of ​​the warehouse, a large amount of manpower and material resources need to be invested, and the time spent is also very long. These methods are labor-intensive, time-consuming, and expensive. very uneconomical

Especially for large-scale dam projects, the number of dam blocks is more, and the storage area is larger. It is very difficult to remove and discharge the accumulated water in the storage area of ​​the dam. Often, due to improper arrangements, we can only adopt the disorderly discharge method of "letting go" , the sewage floods everywhere, pollutes the construction operation environment, and greatly interferes with the follow-up process. As a result, each dam block is often repeatedly treated for accumulated water when preparing warehouses. Some of the accumulated water in the lower positions are extremely difficult to discharge, and the cost of treatment is very high.
