The utility model discloses simple structure, firm durable, the prevention of seepage performance is good, its construction convenience, the raw materials is easily obtained, low cost, even masonry intercepting ditch because of the basic deformation takes place the rivers in fracture, the ditch still can not the infiltration, avoid the side slope to receive the flowing water to erode, fully improve the stability and the security of side slope.
Description
Technical Field
The utility model belongs to the technical field of civil engineering technique and specifically relates to a can resist prevention of seepage intercepting ditch structure that basis warp.
Background
In civil engineering, the slope top intercepting ditch is a common slope intercepting and draining measure. The commonly used intercepting drain has two structures of mortar rubble and cement concrete. After the side slope is excavated, the slope body must generate certain unloading deformation, and because the deformation gradually occurs, the cut-off ditch is subjected to a long basic deformation period after being built. For a soil or gravel soil slope, if the slope body deforms to cause the cut-off ditch to crack, ditch water can quickly seep downwards to cause great adverse effect on the slope stability.
Disclosure of Invention
In order to solve the influence that the ditch underwater seepage caused side slope stability behind the intercepting ditch fracture, the utility model provides a can resist prevention of seepage intercepting ditch structure that the basis warp, specifically can take following technical scheme:
can resist prevention of seepage intercepting ditch structure that basis warp, cross section including offering on the slope is the trapezoidal ditch body, the ditch is internal to have set gradually:
the anti-seepage layer is a composite geotextile which is laid on the surface of the ditch body in a folding mode and coated with a waterproof film;
the buffer layer is a gravel cushion layer laid on the composite geotextile;
and the consolidation layer is a grouted rubble or cement concrete pouring layer poured on the gravel cushion layer.
The surface area of the composite geotextile is 1.2-1.5 times of the surface area in the ditch body.
The waterproof film is a polyvinyl chloride or polyethylene film.
The thickness of gravel bed course is 10 cm.
The utility model provides a can resist prevention of seepage interception ditch structure that basis warp, simple structure, it is firm durable, the prevention of seepage performance is good, its construction convenience, the raw materials is easy, low cost, even masonry interception ditch because of the basis warp the rivers in fracture, the ditch still can not the infiltration, avoid the side slope to receive the flowing water to erode, fully improve the stability and the security of side slope.

Fig. 1 is a schematic structural diagram of the present invention.
Detailed Description
The embodiments of the present invention will be described in detail with reference to the accompanying drawings, and the embodiments of the present invention are based on the technical solutions of the present invention and are described in detail, but the present invention is not limited to the following embodiments.
As shown in figure 1, can resist prevention of seepage intercepting ditch structure that basis warp, include that the cross section of excavation is trapezoidal ditch body on soil property or rubble slope, ditch body bottom surface and side compromise, level and smooth, clean, then set gradually barrier layer 1, buffer layer 2 and consolidation layer 3 in the ditch body. Specifically, the impermeable layer 1 is a composite geotextile which is laid on the surface of the ditch body in a folding mode, and the surface of the composite geotextile is coated with a polyvinyl chloride or polyethylene waterproof film, so that the geotextile has the advantages of corrosion resistance, low temperature resistance, creep resistance, long service life and the like, and has the most important advantages of good tensile strength and elongation rate and can adapt to the deformation of the foundation of the intercepting ditch. In addition, the surface area of the composite geotextile is about 1.2-1.5 times of the surface area in the groove body, the geotextile can be laid in a folded state, the geotextile is prevented from being in a tension state when being laid, meanwhile, the geotextile can be fully prevented from being torn when the groove body deforms and cracks, the seepage-proofing performance is ensured, and the adverse effect on the side slope when the groove body seeps underwater is avoided. The buffer layer 2 is a gravel cushion layer with the thickness of about 10cm, which is laid on the composite geotextile, and can slow down the cracking of the bonding layer 3 to a certain extent when the slope body deforms. The consolidation layer 3 is a grouted rubble or cement concrete pouring layer which is built on the gravel cushion layer, is firm and firm, and can resist water flow scouring and prevent running water from seeping downwards.
To sum up, the utility model discloses a structure of just gentle combination can fully guarantee that the flowing water of masonry intercepting ditch still keeps not oozing after the basis warp the fracture, avoids the side slope to receive flowing water to erode, fully improves the stability and the security of side slope.
