Description
Technical field
The present invention relates to field of road more particularly to a kind of cutting stereoscopic protectives with high polymer grouting reinforcement waterproof
The construction method of structure.
Background technology
Pavement structure is directly exposed among air, undergos the influence of natural environment, the intensity and stabilization of pavement structure
Property depend greatly on the humidity of local environment, excess surface water caused by rainfall and underground water intrusion can all make road surface
Disease is generated, there are many factor for forming disease, and the effect of underground water is one of its principal element.The danger of underground water road pavement structure
The main performance of evil：First, causing purt mud at the seam of cement concrete pavement and curb, traffic safety is influenced, it is strong to reduce road surface
Degree；Second is that erosion of the underground water to bituminous paving so that pitch causes disease from stone surface peeling, influences the pavement usage longevity
Life；Third, under Moving Loads caused purt mud and high pressure water wash away cause sub-surface bearing capacity decline.Therefore road surface
The Lock gate of well-formed is not only pavement strength and the important guarantee of stability, and can be that prolonging service life of pavement is created
Make advantage.
Road project is closely related with natural environment, and project scale is big, project is more, involves a wide range of knowledge, and native stone fills out digging
A large amount of native stone bare side slopings that engineering is formed, destroy existing vegetation, are affected to local environment, previous generally use
Simple engineering protection, it is a series of that these engineering measures result in original vegetation destruction, soil erosion, landslide, slope instability etc.
Ecological environment and engineering problem.
In order to ensure the stabilized soil pavement of cut slope, protection is carried out for cut slope and reinforcing is necessary engineering
Technical measures.As the raising of category of roads reduces highway distress to safeguard normal communications and transportation, it is ensured that traffic safety is protected
It holds highway with natural environment to coordinate, the protection and reinforcing of cut slope are equally of great significance.
In the prior art, for the construction of cutting, there are following main problems：
1, cutting water burst is a kind of relatively common geological disease form of expression, and cutting water burst can corrode pavement structure, make
Obtaining pavement strength reduces, and influences service life of road surface.The measure of existing waterproof is mainly laid with compound water-proof or composite earth
The measures such as work film, hot asphalt or concrete.But these common methods can not have the function that long-term waterproof.Composite water-proof
The seam of plate or composite geotextile often becomes penetrating passage；Meanwhile the quality control requirement of hot asphalt is very high, price is not
It is luxuriant and rich with fragrance；Concrete is fragile material, slightly breathing, is easy for cracking, loses waterproof action.
2, the soil body mainly is fixed using exterior protection structure for the protection of High Cut Slope in the prior art, does not examine
Consider side slope structure itself to be reinforced, this mode is difficult big high, and fastness and stability are unsatisfactory.
Invention content
