Salivary flow ice prevention and management structure in cold zone

Abstract

The invention relates to a salivary flow ice prevention and management structure in a cold zone. The structure is characterized in that heat-insulation plates are laid below an earth filling layer of a slope crest and on a slope surface and the upper middle portion of a drainage ditch, the corresponding heat-insulation plate is connected with the slope surface by anchor rods, a buffering layer is formed in the middle of the drainage ditch by geotextile and fine sand, a surface permeable layer is formed on the top of the drainage ditch by hexagonal hollow bricks and crushed stone, soil with grass seeds is placed in the hexagonal hollow bricks of the slope surface, and an ecological side slope is formed. The heat-insulation plates are laid below the earth filling layer of the slope crest and on the slope surface and the upper middle portion of the drainage ditch, shallow water in an upslope direction flows down along the inner side of the heat-insulation plate of the slope surface, is gathered in the drainage ditch and is drained by the drainage ditch. Surface water is drained via the surface permeable layer. Accordingly, the salivary flow ice prevention and management structure guarantees that an underground drainage line cannot be completely frozen in winters, and salivary flow ice is prevented.

Description

technical field [0001] The invention relates to a structure for preventing saliva ice in cold regions. It is suitable for the prevention and control of salivary ice in excavation engineering sections in cold regions. Background technique [0002] Most of my country's land area is in the cold region. Excavation works in cold regions are very likely to form slope-shaped saliva ice, which endangers the safety of buildings and transportation. The reason for the formation of this disaster is that the excavation cut off the groundwater migration path, so that the water that originally flowed underground flows out on the slope, and slope-type saliva ice is formed in cold climate conditions. [0003] Traditional salivary ice prevention technologies include: hidden pipes, blind ditches, intercepting ditches, ice retaining walls, ice retaining dams, overexcavation, etc. The over-excavation measures will greatly disturb the environment. In recent years, a multi-outlet drainage syst...

Problems solved by technology

In recent years, the multi-outlet drainage system, heat preservation water collection well and heat preservation water outlet have been developed. The above measures have serious defects in the prevention and control of slope ice.
