Precast concrete hydrant protection body

Abstract

The invention discloses a precast concrete hydrant protection body which is composed of a protection body cover, a protection body pipe and a protection body base. The protection body cover is circular, is embedded in a prop in a pipe orifice of the protection body pipe and is flush with the pipe orifice; the protection body pipe is a solid-wall prefabricated concrete pipe, the upper end pipe wallis particularly thickened and gradually transits to the normal pipe wall thickness of the lower middle section, and the inner diameter of the pipe is the same up and down and is not changed; the lower end of the protection body pipe is mounted on the protection body base and in an annular limiting check ring; the protection body base is square, a round hole is reserved in the center of the protection body base to be used for allowing a water supply vertical pipe to penetrate through; the limiting check ring protrudes out of the bottom plate by a certain height and is concentric with the reserved round hole, a certain gap is formed between the limiting check ring and the installed protection body pipe, and cement mortar is filled in the gap to fix the protection body pipe and the protection body base into a whole. According to the precast concrete hydrant protection body, the wall thickness of the upper end is locally and particularly increased, and the double effects of warning and protection are achieved; the buried part at the middle lower end is normal in wall thickness, the use requirement is met, and the material cost is not additionally increased.

Description

technical field [0001] The invention belongs to the technical field of farmland water conservancy, and in particular relates to a prefabricated concrete water supply hydrant protection body. Background technique [0002] At present, my country's farmland water conservancy and water-saving irrigation technology is being widely promoted, and low-pressure pipeline technology is one of them. In this irrigation method, water is delivered through underground horizontal water delivery pipes, and a standpipe is vertically separated to the ground at a certain height at intervals, and a water supply control device is installed for water delivery to the ground. There is a concealed plastic water supply control device, which is installed on the top of the water delivery riser, called the lower water supply cock body, buried at a certain depth below the ground, and connected to the upper cock body to realize the water outlet function. In order to create a working space for the plastic l...

Problems solved by technology

In order to solve this problem, the usual method: 1. Thicken the wall pipe as a whole, but the production, transportation and installation costs increase; 2. Install a prefabricated concrete retainer on the exposed part of the ground, but this will increase the production cost. And the installation cost, and because it cannot be integrated with the protective tube, the combination is loose, it is easy to sink, and the application effect cannot be guaranteed

2. The body protection tube and the base of the existing similar products are stacked together up and down, which can only play an anti-settling effect. Once the upper part of the body protection tube encounters an external force, because the body protection tube and the base are separated, there is no effective combination , the standpipe is easy to tilt and shift, the protection function is lost, and the safety of the lower bolt body of the water supply hydrant is affected
