Drainage method of underground water pipe in dam concrete warehouse area

Abstract

The invention relates to a dam concrete cabin surface water accumulation hidden pipe discharge method. A water discharge main pipe is arranged in a preset region and is communicated with the upstream and the downstream of a dam, water discharge branch pipes are introduced to the left side and the right side of the dam body of the dam from the water discharge main pipe and are communicated with each dam block in a region, and a vertical water discharge branch pipe is connected onto the water discharge branch pipes of each dam block and is communicated with each concrete cabin position in each dam block. The dam concrete cabin surface water accumulation hidden pipe discharge method is characterized in that in the dam concrete casting construction process, the pre-buried water discharge pipenetwork continuously extends and expands to all concrete casting dam blocks along with the dam body concrete casting progress, each newly cast concrete cabin position in the dam region is fully covered, the water discharge problem of large-area accumulated water of the dam concrete cabin surface is solved, a dry ground construction environment condition is created for the concrete casting, the concrete casting quality is ensured, the construction interference is reduced, and the engineering civilization construction is realized.

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.
