Design method of horizontal tube and culvert for check dam

Abstract

The invention discloses a method for designing a lying pipe and a culvert of a silt dam. The method comprises a design method for a lying pipe part and a design method for a culvert part, wherein the design method for the lying pipe part comprises the following: according to the formula of Q=mu A 2gH, cross section area of one or more than one water drain hole on each water drain step is calculated, and the design method for the lying pipe part also comprises the design for the sizes of a square lying pipe, a circular lying pipe and a stilling pool and the design for the thickness of a cover plate and the side walls; and the design method for the culvert part comprises the design for the culvert size and the design for the wall thickness and reinforcing bars. The whole design process is clear, and the design result is accurate.

Description

technical field The invention relates to a design method of a check dam waterproof structure, in particular to a design method of a check dam horizontal pipe and a culvert. Background technique Water release structures are an important part of check dam engineering. The water discharge structure of the check dam in the prior art generally consists of three parts: a water intake structure, a water discharge culvert, and an outlet energy dissipation section. Water intake structures usually use horizontal pipes or vertical shafts, and are connected to water discharge culverts through stilling basins. As shown in Figure 1 and Figure 2, the horizontal pipe is a kind of opening and closing equipment for segmental discharge of water, and generally adopts square masonry or circular reinforced concrete structure. The upper end of the horizontal pipe is provided with a ventilation hole 1, and a water discharge hole 2 is established every 0.4 to 0.5m (vertical distance) on the pipe,...
