Embodiment Construction
[0036] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments, but the present invention is not limited to these embodiments.
[0037] like Figure 1 to Figure 8 As shown, a kind of pier concrete heat preservation and health maintenance equipment in low temperature season, including a heat preservation device and a steam supply device arranged around the pier formwork 5 outside the pier concrete. The thermal insulation device ensures that the concrete pier column and the pier column formwork form a closed environment, and provides suitable temperature conditions for the solidification and hardening of the pier column concrete. The steam device provides suitable temperature and humidity conditions for the hydration reaction of concrete.
[0038]The heat preservation device includes a heat preservation cylinder sleeved on the outside of the pier formwork 5, and the heat preservation cylinder include...

The invention discloses equipment for insulating and curing pier column concrete in low-temperature seasons, solving the problem that the curing effects of the existing concrete in winter are not ideal. The curing equipment comprises an insulation device and a steam supply device, wherein the insulation device comprises an insulation cylinder arranged outside a pier column formwork in a sleeving manner; the steam supply device comprises a steam generator and a vent pipe; the steam generator is arranged outside the insulation cylinder; one end of the vent pipe is connected with the steam generator and the other end is sealed; the vent pipe is wound around the outer side of the pier column formwork; and a plurality of steam outlet holes facing the inner wall of the insulation cylinder are formed in the vent pipe. The curing equipment can ensure the temperature and humidity of the surface of the pier column concrete to be relatively uniform by being utilized to cure the pier column concrete for winter construction.
Description
technical field [0001] The invention belongs to the technical field of highway and bridge construction, and in particular relates to a pier column concrete thermal insulation and health maintenance equipment in low temperature season. Background technique [0002] Many places in our country have long cold weather. Due to the constraints of the construction period, the concrete winter construction of many projects is inevitable. The construction of concrete in winter construction is safe, with high quality risks and low production efficiency. The quality after pouring will directly affect its performance. [0003] At present, there are many methods for concrete winter insulation and maintenance at home and abroad, usually including greenhouse method, thermal storage method, steam heating method, electrode heating method, electric heating model method, far-infrared heating method and so on. [0004] Among them, the greenhouse method is a common method for concrete maintenance...
