Abstract

The invention relates to a vehicle-mounted earth material freezing prevention and control system. The system comprises a tail gas collector (2) and a tail gas filter (3) which are arranged at a tail gas exhausting cylinder (1) of an earth material transporter, a gas pressurizer (7) which is communicated with the tail gas filter (3) and is arranged at the top surface of the vehicle head, and multiple dispersion pipes (5) which are communicated with the gas pressurizer (7) and are arranged inside the carriage. The dispersion pipes (5) are provided with multiple dispersion holes (9) for pressurized hot gas to disperse, and the dispersion holes (9) are provided with protection lids (10). According to the vehicle-mounted earth material freezing prevention and control system, in a transportation process, heat carried in the tail gas can be effectively utilized to raise the temperature of the earth material or defreeze the earth material, the vehicle-mounted earth material freezing prevention and control system is applicable to earth material freezing prevention and control in construction engineering in a cold area or a seasonal frozen soil area, the quality problems of engineering filling that the compactness, the permeability and the strength do not meet the requirements due to the frozen earth material are avoided, and the achievement of continuous construction in a low-temperature environment is guaranteed.

Description

technical field [0001] The invention relates to the field of soil freezing prevention and control, in particular to a vehicle-mounted soil freezing prevention and control system. Background technique [0002] Frozen soil is a kind of soil rock with a temperature below 0°C and contains ice. The water in the soil freezes into ice, causing the volume of the soil to expand, and the strength of frozen soil is much greater than that of unfrozen soil. When the temperature rises, the permafrost melts to form thawed soil. At this time, the volume of the soil shrinks, the strength will also decrease, and the permeability will increase. [0003] Seasonally frozen soil and permafrost are widely distributed in the northern and western mountainous and plateau cold regions of my country, accounting for about 70% of China's total land area. In recent years, with the active promotion of the western development, major projects related to energy, transportation, water conservancy, etc. are gr...
