Embodiment Construction

[0031] The construction process flow chart and key points of operation of the present invention are described in detail.

[0032] Operation points:

[0033] Construction preparation:

[0034] 1. Install the greenhouse: the size of the greenhouse depends on the volume of the curing concrete, and scaffolding is used to build the skeleton and reinforce it. Use plastic sheets and tarpaulins for covering and reinforcement (use plastic sheets on the inside and tarpaulins on the outside), so that a closed space is formed inside the tarpaulin, and maintenance is carried out in the closed space, and the liquefied water and hot steam will not be lost.

[0035] 2. Distribution of steam pipes in the greenhouse: The curing effect directly depends on the distribution of steam pipes in the greenhouse, and the steam pipes are laid vertically in the air. It can effectively make the steam circulate in the closed space, so as to quickly increase the temperature in the space. The steam pipe is...

Abstract

The invention relates to curing of concrete in winter or a low-temperature environment, in particular to a construction method for curing the concrete in winter by an all-automatic electric steam generator. The all-automatic electric steam generator controls water quantity and heating time in a furnace pipe mainly through a set of automatic control devices; electrical heating tubes in the furnacepipe are continuously heated to generate steam without stop; a steam outlet is externally connected with a heat preservation rubber tube having a breather hole, and hot steam is sent into an enclosedspace which needs to be cured; and the hot steam moves up, so that temperature and humidity in the enclosed space rise, and the goal of concrete curing is achieved. The construction method is suitablefor curing engineering construction performed in winter or the low-temperature environment, and mainly comprises curing performed on concrete structures under the conditions of large difference in temperature between day and night and low temperature (below zero).

Description

technical field [0001] The invention relates to the maintenance of concrete in a low-temperature environment in winter, in particular to a construction method for winter maintenance of concrete with a full-automatic electric steam generator. Background technique [0002] In winter construction, the ambient temperature drops, the moisture contained in soil, concrete, mortar, etc. freezes, and building materials are prone to brittle cracks, which brings many difficulties to construction. At present, concrete curing in low-temperature environment in winter generally adopts coal-fired steam curing. Coal-fired steam will inevitably bring about environmental protection problems, and the cost of coal-fired steam curing is also high. Contents of the invention [0003] Aiming at the problem of concrete maintenance in low-temperature environment in winter, the present invention selects electric heating steam curing to ensure concrete strength and various performances, and is specifi...
