Embodiment Construction

[0004] A mechanical construction process for underwater concrete, the steps are as follows:

[0005] 1. Use a concrete forced mixer to forcibly mix high-performance underwater concrete.

[0006] 2. Import the mixed high-performance underwater concrete into the concrete powerful pump.

[0007] 3. Use a powerful concrete pump to pump the high-performance underwater concrete to the pouring base through the underwater conduit.

[0008] Compared with the existing underwater concrete pouring technology, the present invention has the following advantages: the use of high-performance underwater concrete with good dispersion resistance, good fluidity, fast setting time, high early strength, and rapid development of later strength, and the use of forced concrete The mechanized operation of mixing and high-power pumping greatly improves work efficiency, reduces labor intensity, and provides a new construction method for rapid and large-scale pouring of underwater concrete.

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 [0001] The invention belongs to the technical field of underwater concrete construction, and in particular relates to a mechanical construction method of underwater concrete. Background technique [0002] With the needs of the development of modern construction, the construction of hydraulic structures such as dams, reservoirs, bridges, pile foundations, marine engineering, etc., all involve the engineering technology of constructing concrete underwater. However, ordinary concrete is easily dispersed, causing concrete to segregate. Phenomenon, resulting in a sharp decline in concrete strength, underwater non-dispersible concrete currently on the market, due to the addition of conventional anti-dispersion agents, although the anti-scouring ability of cement paste is improved, the fluidity is hindered, and the concrete strength decreases. In the existing underwater concrete construction process, conventional concrete mixing and conveying equipment is mostly use...
