The invention discloses a waterproof structure suitable for a green assembled soil nailing wall, comprising a waterproof skin layer, a reinforced protective layer, soil nails, a waterproof mechanism and a green assembled surface layer. The waterproof mechanism is composed of a drain pipe and a water stopper. It is composed of a rubber ring. The green prefabricated surface layer, soil nails and waterproof mechanism are combined into one to form a waterproof green prefabricated soil nail wall. This protective structure enables the overall waterproof function of waterproofing inside the slope and leaking water outside the slope. achieve while reducing soil erosion on slopes. The invention has the characteristics of simple and quick installation, especially for the protection of water-containing gravel and sand layers, and the effect is more obvious than the traditional technology. Stable installation improves soil protection between piles and provides flatness requirements for the next process.
Description
Technical Field
The invention relates to the technical field of constructional engineering, in particular to a waterproof structure suitable for a green assembly type soil nailing wall.
Background
The traditional processes such as traditional spraying and mixing masonry protection play a role in protecting slopes, but the spraying and mixing masonry has poor protection effect on gravel layers, the gravel layers are generally loose and have strong water-rich property, soil bodies among piles are easy to lose, and finally the protection among the piles is failed, so that cavities appear.
Disclosure of Invention
The present invention has been made to solve the above-mentioned problems, and an object of the present invention is to provide a waterproof structure suitable for a green fabricated soil nailing wall.
In order to achieve the purpose, the invention provides the following technical scheme: including green assembled surface course, soil nail, outlet pipe and stagnant water rubber ring, its characterized in that: the green assembled surface layer, the soil nails, the water drain pipes and the water stop rubber rings are combined into a whole to form a side slope stress waterproof system, and the side slope waterproof system is adopted to realize the overall waterproof functions of water inside a slope and water outside the slope, and reduce the water and soil loss of the slope surface.
Preferably, the green assembled surface layer consists of a waterproof skin layer and a reinforced protective layer.
Preferably, the waterproof skin layer is a waterproof roll.
Preferably, the reinforced protective layer is formed by combining a reinforced layer and a protective layer, the reinforced layer is made of a high polymer composite material, and the protective layer is made of a green, light and flexible material.
Compared with the prior art, the invention has the beneficial effects that: the invention has the characteristics of simple and quick installation, and has more obvious effect compared with the traditional process particularly for the protection of water-containing gravel and sand layers. The stable installation improves the soil body protection between the piles and provides the requirement of flatness for the next procedure.

FIG. 1 is a schematic view of the structure of the present invention.
FIG. 2 is a cross-sectional view of the structure of the present invention.
In the figure: 1-waterproof skin layer, 2-reinforced protective layer, 3-water drain pipe, 4-water-stopping rubber ring, 5-soil nail and 6-green assembled surface layer.
Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Referring to fig. 1-2, the present invention provides a technical solution: comprises a green assembled surface layer 6, soil nails 5, a water drain pipe 3 and a water stop rubber ring 4, wherein the green assembled surface layer 6, the soil nails 5, the water drain pipe 3 and the water stop rubber ring 4 are combined into a whole to form a slope stressed waterproof system,
the green assembled surface layer 6 is composed of a waterproof skin layer 1 and a reinforced protective layer 2, the green assembled surface layer 6 can achieve the function of preventing the streaming, and water in the soil layer is discharged through the drain pipe 3.
The waterproof skin layer 1 is a waterproof roll.
The reinforced protective layer 2 is formed by combining a reinforced layer and a protective layer, the reinforced layer is made of a high polymer composite material, and the protective layer is made of green, light and flexible materials.
Further, the green assembled surface layer 6 is used in combination with lightweight filler. The light filling material is mainly a light material, can be a light filling foam material, can be closely combined with a soil layer and a surface layer, and can prevent water and soil in the soil layer between piles from permeating and losing.
The working principle of the invention is as follows: in the construction process, the foundation pit needs to be excavated in layers, the excavation depth needs to be combined with construction requirements, when the layered excavation depth reaches 2-3m, a base layer between piles needs to be cleaned, expansion bolts are driven into the base layer at equal intervals, the diameters of the expansion bolts can be selected to be 12-20mm according to stress requirements, the drawing force of the expansion bolts with the diameters of 12mm can reach 35.6kn, then the waterproof skin layer 1 and the reinforced protective layer 2 are vertically paved in sequence, the waterproof skin layer 1 is prevented from being damaged by the bolt heads, the flexible wrapping can be carried out on the waterproof skin layer 1, gaps existing behind the reinforced protective layer 2 can be filled with light fillers, and the flatness of the surface layer of the reinforced protective layer 2 is ensured. And (5) 1-2d after the installation and the laying are finished, the self-standing condition can be achieved, and the second layer of construction is carried out.
It will be evident to those skilled in the art that the invention is not limited to the details of the foregoing illustrative embodiments, and that the present invention may be embodied in other specific forms without departing from the spirit or essential attributes thereof. The present embodiments are therefore to be considered in all respects as illustrative and not restrictive, the scope of the invention being indicated by the appended claims rather than by the foregoing description, and all changes which come within the meaning and range of equivalency of the claims are therefore intended to be embraced therein. Any reference sign in a claim should not be construed as limiting the claim concerned.
