Abstract
The invention belongs to the technical field of underwater concrete mechanical construction and particularly relates to a full-mechanic underwater concrete construction method. According to the method, high-performance underwater concrete, a concrete mixer, a concrete conveying pump and an underwater guide pipe are included. The mechanic construction system effectively solves the technical problem of underwater construction with the high-performance underwater concrete. The method includes the following steps that the concrete mixer stirs the high-performance underwater concrete with strong force, and then guided into the concrete conveying pump and pumped to a pouring base plane through the underwater guide pipe to finish a pouring process of the underwater concrete. According to the method, mechanical work is adopted, the construction efficiency is greatly improved and the construction period is shortened.
Description
Technical field
The invention belongs to the technical field of underwater concrete construction, be specifically related to a kind of mechanical execution method of underwater concrete.
Background technology
Needs along with modernization construction development, the construction of hydraulic architecture such as dam, reservoir, bridge, pile foundation, ocean engineering etc., all relate to the concrete engineering of constructing under water, yet ordinary concrete very easily disperses, make concrete produce segregation phenomenon, and cause the sharply decline of concrete strength, non-dispersible underwater concrete in the market, due to admixture conventional anti-dispersant, although improved the erosion resistibility of cement slurry, but mobility is obstructed, concrete strength declines.In existing underwater concrete construction process, conventional concrete-agitating and the conveying equipment of many employings, but along with scientific and technical progress, after novel high-performance underwater concrete is put on market, these plant equipment cannot meet the construction needs of underwater concrete engineering, and the mechanical execution method of therefore researching and developing novel underwater concrete is imperative.
Summary of the invention
The present invention is in order to solve a construction technology difficult problem for novel high-performance underwater concrete, a kind of mechanical execution method of underwater concrete is provided, by adopting forced concrete mixer, the mechanized construction method that powerful powerful delivery pump and corresponding conduit are under water set up is carried out concrete construction casting under high-performance water.
The specific embodiment:
A mechanical execution technique, step is as follows:
1, with concrete forced mixer, high-performance underwater concrete is carried out to action of forced stirring.
2, the high-performance underwater concrete being stirred is imported in concrete strengthening pump.
3, with concrete strengthening pump, high-performance underwater concrete is delivered to and built basal plane through catheter pump under water.
The relatively existing underwater concreting technology tool of the present invention has the following advantages: use has fine anti-dispersiveness, good fluidity, time of setting is fast, early strength is high, later strength development high-performance underwater concrete rapidly, adopt forced action type to stir simultaneously, the do mechanization operation of high-power pumping, operating efficiency is provided greatly, reduce labor intensity, for quick and large area, build underwater concrete a kind of novel job practices is provided.
Claims (5)
1. the mechanical execution method of a underwater concrete, it is characterized in that this job practices is employing concrete mixer, concrete pump, conduit forms under water, its step is for first carrying out strong stirring with concrete mixer to high-performance underwater concrete, after allowing, import again concrete pump, finally by catheter pump under water, deliver to and build basal plane, complete building of underwater concrete.
2. the mechanical execution method of a kind of underwater concrete according to claim 1, it is characterized in that described underwater concrete is for being difficult under water dispersion, good fluidity, time of setting is fast, early strength is high, and later strength develops high-performance underwater concrete rapidly.
3. the mechanical execution method of a kind of underwater concrete according to claim 1, is characterized in that described concrete mixer is forced mixer.
4. the mechanical execution method of a kind of underwater concrete according to claim 1, is characterized in that described concrete pump is powerful delivery pump
5. the mechanical execution method of a kind of underwater concrete according to claim 1, is characterized in that described conduit is under water the conduit of metal or other hard material.
