Digital constant-temperature control concrete ultra-low-temperature construction maintenance system

Abstract

The invention discloses a digital constant-temperature control concrete ultra-low-temperature construction maintenance system, which comprises a sliding template, a data collecting device, a wireless transmission device and a heating control device, wherein a heat insulation shed is arranged on the outer periphery of the sliding template, a steel plate hanging frame is arranged at the lower part of the sliding template, four electronic heating quilts are suspended on the steel frame hanging frame, the four electronic heating quilts are surrounded into a barrel-shaped sealing head insulation cover, each electronic heating quilt is respectively and sequentially formed by connecting a high-intensity glass fiber layer, a heat tape and a heat insulation cotton layer from inside to outside, a plurality of temperature sensors are arranged on each electronic heating quilt, and all temperature sensors and heat tapes are respectively connected with the data collecting device, the wireless transmission device and the heating control device. Good heating and heat insulation effects can be realized, and the heat loss during the concrete casting can be effectively prevented. When the environment temperature is minus 30 DEG C, the temperature on the surface of the concrete can be enabled to be higher than 5 DEG C, so the cold damage and the crack occurrence on the surface of the concrete can be prevented, and the casting quality of bridge piers can be ensured.

Description

technical field [0001] The invention relates to a digital constant temperature control concrete ultra-low temperature construction and maintenance system. Background technique [0002] At present, the pouring construction of bridge pier concrete cannot be carried out in the low temperature environment in winter. The main reason is that in winter, the temperature is low and the wind speed is fast, which makes the temperature difference between the inside and outside of the concrete larger; when the temperature difference between the inside and outside exceeds 25 degrees, cracks will appear on the surface of the concrete, which directly affects the quality of the bridge piers. SUMMARY OF THE INVENTION [0003] The purpose of the present invention is to provide a digital constant temperature control concrete ultra-low temperature construction and maintenance system, which can play a good role in heating and heat preservation, and can effectively prevent heat loss during concr...
