Title:
FOUNDATION PIT RESCUE GROUTING TEMPERATURE CONTROL DEVICE AND APPLICATION METHOD THEREOF
Document Type and Number:
WIPO Patent Application WO/2021/073208
Kind Code:
A1
Abstract:
A foundation pit rescue grouting temperature control device and an application method thereof. The foundation pit rescue grouting temperature control device comprises a temperature controller (10), and a heating component and a temperature sensor (12) separately connected to the temperature controller (10). The temperature controller (10) controls the heating component to raise the temperature reached by a grouting pipe (20) according to a temperature of the grouting pipe (20) sensed by the temperature sensor (12), thereby increasing the temperature of polyurethane in the grouting tube (20) in a low temperature environment, improving a curing speed of the polyurethane in contact with moistures, and effectively solving the problem of slow curing speed of polyurethane for foundation pit rescue under the low temperature environment. In addition, because the temperature controller (10) can control a heating temperature and effectively control a heating time node, the danger of preheating the polyurethane in advance is avoided and the impact on the environment is reduced. In conclusion, the foundation pit rescue grouting temperature control device provided by the present invention has the properties of convenient operation, simple and quick installation and maintenance, safety, and a pollution-free property.
