Electric inflatable concrete formwork sealing device

Abstract

An electric inflatable concrete formwork sealing device comprises an airbag and an air delivery pipe. One end of the air delivery pipe is adhered with the airbag. The electric inflatable concrete formwork sealing device is simple in structure, good in sealing effect and high in practicability.

Description

technical field [0001] The invention relates to the technical field of concrete engineering, in particular to an electric inflatable concrete formwork sealing device. Background technique [0002] Concrete structures are applied to many projects, such as road and bridge projects, municipal engineering, water conservancy projects, housing construction projects, ports, docks and nuclear power plants, etc. These projects often use concrete retaining walls during construction, and concrete retaining walls The common problem of rotten roots often occurs in the wall, and the common problem of rotten roots is the most troublesome problem for engineers and technicians and 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 affects people. catastrophic loss of life and property. The reasons for this are as follows. First, when pouring the concrete retaining wall, the formwo...

[0002] Concrete structures are applied to many projects, such as road and bridge projects, municipal engineering, water conservancy projects, housing construction projects, ports, docks and nuclear power plants, etc. These projects often use concrete retaining walls during construction, and concrete retaining walls The common problem of rotten roots often occurs in the wall, and the common problem of rotten roots is the most troublesome problem for engineers and technicians and 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 affects people. catastrophic loss of life and property

The reasons for this are as follows. First, when pouring the concrete retaining wall, the formwork at the root is not tightly sealed and the grout leakage is serious. The lower end of the formwork is a strip foundation, and the gap between the concrete or the top surface of the concrete and the formwork is difficult Sealing, resulting in grout leakage, the only formwork sealing double-sided adhesive used during construction, and the double-sided adhesive sealing of the formwork has no effect on the common problem of concrete water retaining and root rot, because the top surface of the strip foundation or the concrete raft foundation is Handmade, uneven and poor precision; second, the vibration time is short, and the gas in the concrete is not discharged; third, the steel bars are dense, the concrete slump is small, or the particle size of the stone is large; fourth, human factors, etc.

After the root rot of the 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, and the steel bars are corroded. Not only do they fail to meet the design requirements, but in severe cases, they need to be demolished and redone. At present, the latter three factors It has been solved, only the first factor that causes root rot is still perplexing our engineering and technical personnel and construction teams
