Description
Technical field
The present invention relates to landslide disaster prevention engineering field more particularly to a kind of earth-retaining nets and landslide anti-slide pile-earth-retaining net
Joint retaining system.
Background technique
In China, because 70% region is mountain area, therefore landslide disaster generation density is big, and frequency is high, and China has become in the world
It is hundreds of millions of because being lost caused by landslide disaster every year by landslide one of the countries with the most serious ..., give the country and people's life
Property brings massive losses, generates serious social influence.In many landslide disaster prevention measures, since pile plate wall has antiskid
The advantages that effect is good is widely used in landslide control engineering.
Pile plate wall is to utilize antiskid by friction pile and retaining plate between piles a kind of joint prevention and treatment landslide structure dimerous
The elastic resistance of the following anchorage part stake surrounding soil of the intensity and sliding surface of stake body pushes away to balance the remaining landslide of sliding surface or more
Power makes landslide keep stablizing, then friction pile is connected by breast boards, the loose soil body between interception friction pile, and will
The soil pressure and thrust of inter-pile soil body pass to stable stratum by friction pile, to make the come down soil body and this control structure guarantor
It is fixed to keep steady.Due to the presence of breast boards, good sealing effect is played to inter-pile soil body or soft rock, is conducive to the long-term of landslide
Stablize.
However the breast boards structure type of traditional pile plate wall is upright full closeding state, project amount is big, and drainage effect is poor.
When slip mass it is aqueous it is abundant, landslide thrust body is huge when, current peg board wall construction due to there is a problem of that drainability is limited,
Generally requiring increasing structure design size can be only achieved the effect of the unstable slopes of supporting and retaining system, so as to cause engineering construction and its later period
Maintenance cost it is sufficiently expensive.
