Abstract

The invention discloses a mass concrete construction device and method in a marine environment, and the construction device comprises a bottom plate, a formwork erecting assembly and a partition assembly, wherein the surface of the bottom plate is provided with a positioning groove and a positioning ring; the formwork erecting assembly comprises formworks and fastening assemblies, and the multiple formworks are connected in an inserted mode to define a concrete pouring space; the partition assembly is located in the concrete pouring space, the partition assembly comprises a stand column, partition plates and a connecting rod, the stand column is vertically arranged on the positioning ring and located in the center of the concrete pouring space, the multiple partition plates are connected with one another and arranged on the periphery of the stand column in a surrounding mode, and the multiple connecting rods are correspondingly connected with the stand column and each partition plate, and a fixing rod is arranged at the joint of every two adjacent partition plates. According to the construction method, layered and partitioned pouring is adopted, the highest temperature of the concrete can be reduced, the internal and external temperature difference can be reduced, constraint between new concrete and old concrete can be reduced, and the construction method is suitable for temperature control anti-cracking measures in the marine environment.

Description

technical field

[0001] The invention relates to the technical field of material detection. More specifically, the present invention relates to a large-volume concrete construction device and construction method in a marine environment. Background technique

[0002] Affected by the temperature and temperature changes of itself and the surrounding medium, as well as the effect of foundation constraints, mass concrete often produces large restraint stresses in different parts, and cracks are easily generated, which not only affects the appearance and normal operation of the project, but also may affect the quality of the project. It is safe and shortens the life of the project. In the marine environment, the concrete used is more prone to temperature cracks due to the large amount of cementitious materials, high heat of hydration and large self-shrinkage of concrete. Therefore, there is an urgent need to provide a large-volume concrete construction device and construction meth...
