Abstract

The invention discloses an intelligent temperature control electric heat tracing device for a concrete pump pipe in winter construction. The intelligent temperature control electric heat tracing device comprises an electric heating tape, a pressure sensitive adhesive tape, a thermal insulation material, an intelligent temperature control device and the concrete pump pipe, wherein the electric heating tape is wound on the concrete pump pipe and is fixed by pressure sensitive adhesive; a temperature sensor is tightly attached to the outer pipe wall of the concrete pump pipe; the thermal insulation material covers the concrete pump pipe; the two ends of the electric heating tape are connected with a power supply junction box and a tail end sealing junction box which are connected with the intelligent temperature control device; the intelligent temperature control device is connected with a 36V transformer, a distribution box, a leakage protection device and a 220V / 360V power supply junction box in sequence. The device solves the problems of heating and heat preservation for the concrete pump pipe during the winter construction period at severe cold areas, the heat loss of concrete during the concrete pumping process is reduced, the concrete pump pipe is prevented from being iced and blocked during water washing, and intelligent temperature control is realized, so that the labor cost is reduced; moreover, all materials can be utilized repeatedly, so that the material-saving, energy-saving and environment-friendly requirements for green construction are realized.

Description

Technical field [0001] The invention relates to the field of electric heating devices, in particular to an intelligent temperature control electric heating device for concrete pump pipes in winter. Background technique [0002] With the increasing prosperity of China’s construction industry, a large number of domestic urban commercial complexes have begun to be constructed. Under objective conditions such as the pursuit of profit maximization and the gradual reduction of construction period of construction contractors, construction projects are basically irrespective of seasons, regions, and day and night. Continuous construction. During winter construction in severe cold or cold regions, the problem of concrete pumping has become a key factor restricting the construction progress. However, when the traditional method uses thermal insulation materials to passively heat the concrete pump pipes, the temperature of the concrete under the condition of ultra-long-distance concrete pum...

Problems solved by technology

During winter construction in severe cold or cold regions, the problem of concrete pumping has become a key factor restricting the construction progress. When traditional methods use thermal insulation materials to passively insulate concrete pump pipes, the temperature of concrete under the condition of ultra-long-distance pumping of concrete The loss is large and the mold entry temperature cannot meet the specification requirements, and the phenomenon of concrete pump pipe blockage is prone to occur, which not only directly causes huge economic losses and delays in the construction period, but also causes problems in the construction quality of concrete structures. win-win goal
