Underwater concrete mechanical construction method

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.

[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. Currently, the underwater non-dispersible concrete on the market, due to the addition of conventional anti-dispersion agents, although the anti-scourability of the cement paste has been improved, the fluidity is hindered and the concrete strength is reduced.

In the existing underwater concrete construction process, conventional concrete mixing and conveying equipment is mostly used, but with the advancement of science and technology, after the new high-performance underwater concrete is put on the market, these mechanical equipment can no longer meet the requirements of underwater concrete engineering. Therefore, it is imperative to develop new mechanical construction methods for underwater concrete
