Template sealing equipment for preventing root rot of water conservancy and hydropower engineering retaining wall

Abstract

The invention discloses template sealing equipment for preventing root rot of a water conservancy and hydropower engineering retaining wall. The equipment consists of a flexible tubular body, springs, cylinders, conical bodies, circular truncated cones and an adhesive body; the springs are uniformly distributed in the flexible tubular body; the lower ends of the springs are connected with the circular truncated cones in an inserting manner; the circular truncated cones are bonded with the flexible tubular body; the upper ends of the springs bear and are inserted in the cylinders; the conical bodies is welded on the cylinders, and penetrates through an upper side wall of the flexible tubular body; and the adhesive body is adhered to the flexible tubular body. The equipment is simple, novel and reasonable in structure, easy to manufacture, convenient to operate and high in practicability, can prevent generation of the common problem of root rot of a reinforced concrete retaining wall, and can realize good appearance effect, high quality and long service life of the reinforced concrete retaining wall.

Description

technical field [0001] The invention relates to the technical field of water conservancy and hydropower engineering, in particular to a template sealing device for preventing root rot of a retaining wall of a water conservancy and hydropower project. Background technique [0002] Concrete structures are applied to many projects, such as water conservancy and hydropower projects, housing construction projects, municipal projects, roads and bridges, ports, docks, nuclear power plants and other projects. Concrete retaining walls are often used in such projects, and reinforced concrete retaining walls A common problem of rotten roots often occurs. The common problem of rotten roots has not been solved so far. It not only affects the appearance of the project, but also seriously affects the structural quality and life of the project, and even causes catastrophic losses to people's lives and property. The reasons for this are as follows. First, the lower end of the formwork at the...

[0002] Concrete structures are applied to many projects, such as water conservancy and hydropower projects, housing construction projects, municipal projects, roads and bridges, ports, docks, nuclear power plants and other projects. Concrete retaining walls are often used in such projects, and reinforced concrete retaining walls A common problem of rotten roots often occurs. The common problem of rotten roots has not been solved so far. It not only affects the appearance of the project, but also seriously affects the structural quality and life of the project, and even causes catastrophic losses to people's lives and property. The reasons for this are as follows. First, the lower end of the formwork at the root of the reinforced concrete retaining wall is not tightly sealed and has serious grout leakage. The lower end of the formwork is a strip foundation. The only formwork sealing double-sided adhesive used during the construction of the project has no effect on the common root rot of the reinforced concrete retaining wall, because the strip foundation or the reinforced concrete raft or the top surface of the concrete structure is handmade, uneven and poor in precision; Second, the vibration time is short, and the gas in the reinforced concrete is not discharged; third, the reinforcement is dense, the concrete slump is small or the stone particle size is large; the fourth is human factors, etc.

After the root rot of the reinforced concrete retaining wall occurs, it can be seen that the appearance quality is poor, the compactness is poor, the steel bars are exposed, the wall seeps, the steel bars are corroded, and the design requirements cannot be met. In severe cases, it needs to be demolished and redone, resulting in heavy losses. The three factors have been resolved, and only the first factor that causes root rot is still bothering our engineering and technical personnel and construction teams
