Abstract
The invention relates to a slope protection structure for reducing water and soil loss of a side slope and a construction method thereof. The invention aims to provide the slope protection structure for reducing the water and soil loss of the side slope and the construction method for the structure so as to prevent water on the surface of the side slope from flowing into and secondarily permeating the slope body and scouring the surface of the side slope, ensure the stability of the side slope and reduce the water and soil loss. The invention adopts the technical scheme that: the slope protection structure for reducing the water and soil loss of the side slope is provided with the side slope, and sash beams are arranged on the surface of the side slope. The slope protection structure is characterized in that: the sash beams are obliquely and crossly arranged and embedded into the side slope, and the top surfaces of the sash beams are flush with the slope surface; the top surfaces of the sash beams are provided with grooves along the length direction; and the bottoms of the sash beams are communicated with a drainage ditch formed at the foot of the slope. The slope protection structure is suitable for landslip treatment and side slope projects.
Description
Technical field
The present invention relates to a kind of protective slope structure and job practices thereof that reduces the side slope soil erosion, be applicable to landslide control and slope project.
Background technology
In landslide processing and slope project, underground water and surface water (comprising rainfall) are the key factors that influences stability of slope and cause soil erosion.For getting rid of underground infiltration, dewatering, general way is at the domatic drain hole that is provided with, with underground infiltration drainage to side slope surface or adopt the drainage pipeline networks ejectment; Infiltrate in the body of side slope slope for reducing surface water, general way is in side slope trailing edge periphery catchwater to be set, and draws the side slope upland water to cut.But drain hole row is caused the underground infiltration on side slope surface and the surface water on side slope surface itself, normally let alone, converge to the side slope sough and drain along the slope gravity flow.In the process of side slope surface water along slope gravity flow, possible secondary infiltrates in the sloping body of side slope, and along with the increase of the flow that confluxes, very easily causes slope wash, and then influence stability of slope and cause soil erosion.
Summary of the invention
The technical problem to be solved in the present invention is: at the problems referred to above, a kind of protective slope structure that reduces the side slope soil erosion is provided, and provide the job practices of this structure, being intended to avoid side slope surface water gravity flow secondary to infiltrate sloping body reaches washing away that cause on the side slope surface, guarantee stability of slope, reduce soil erosion.
The technical solution adopted in the present invention is: reduce the protective slope structure of side slope soil erosion, have side slope, be furnished with the sash beam on it is domatic, it is characterized in that: described sash beam inclination arranged crosswise and being embedded in the side slope, and its end face is with domatic concordant; At the end face of sash beam, be shaped on groove along its length direction; The bottom of sash beam is communicated with the gutter that the toe place is provided with.
Described sash beam is arranged with oblique 45 ° of square crossings.
The cross section of described groove is " V " font or " U " font.
Each seamed edge of described groove adopts rounding to handle.
The job practices of protective slope structure of the present invention may further comprise the steps:
A, at side slope surface according to sash beam appearance and size fluting, the groove of being opened is arranged with oblique 45 ° of square crossings;
B, sash beam adopt prefabricated or cast-in-place mode to make, and back portion makes groove, and each seamed edge of groove adopts rounding to handle;
C, the sash beam is embedded in the groove of being opened, and the position of conditioning box lattice beam, the sash top surface of the beam is flushed with domatic;
D, at the toe place gutter is set, sash beam bottom is connected with this gutter.
The invention has the beneficial effects as follows: the surface protection of sash beam is a side slope slope protection mode commonly used, and the present invention changes traditional sash beam surface protection mode, structure and arrangement to its sash beam improve: sash beam inclination arranged crosswise and being embedded in the side slope, its end face is with domatic concordant, the sash top surface of the beam is shaped on groove, and sash beam bottom links to each other with the gutter at toe place.Groove can intercept domatic water in each sash and be collected to the gutter and drain, thereby avoids side slope surface water gravity flow secondary to infiltrate sloping body and to washing away that cause on the side slope surface, both guaranteed the stable of side slope, has reduced soil erosion again.

The specific embodiment
Embodiment one:
As shown in Figure 1, present embodiment has side slope 1, for strengthening the steadiness of this side slope, is furnished with sash beam 2 on it is domatic.
As shown in Figure 1 and Figure 2, different with traditional sash beam protective slope structure, in the present embodiment, sash beam 2 inclination arranged crosswise (so-called " inclination ", be meant every sash beam horizontal by certain angle α, preferred oblique 45 ° of square crossings arrange, i.e. α among Fig. 1=45 °).The end face of sash beam is shaped on the groove 2-1 that the cross section is " V " font, and groove is offered along sash beam length direction, is used to intercept the water that confluxes on domatic, and each seamed edge of groove 2-1 adopts rounding to handle, in order to smooth overcurrent.Sash beam 2 is embedded in the side slope, and its end face imports in order to domatic water within the groove of sash beam smoothly with domatic concordant.Sash beam 2 lower ends are connected with the gutter 3 that the toe place is provided with, and make the domatic water that confluxes finally by the gutter ejectment.
The job practices of present embodiment is:
A, since sash beam 2 need to embed in the side slope 1, so at first on the side slope surface above the excavation place 4 according to sash beam appearance and size fluting, the groove of being opened is with oblique 45 ° of square crossings layout;
B, sash beam 2 adopt prefabricated or cast-in-place mode to make, system groove 2-1 on it, and each seamed edge of groove adopts rounding to handle;
C, sash beam 2 is embedded in the groove that step a opened, and the position of conditioning box lattice beam, the end face of sash beam is flushed with side slope surface;
D, at the toe place gutter 3 is set, sash beam bottom is communicated with this gutter 3.
The spacing of sash beam and the cross section of groove need to determine according to the side slope physical condition.
The operating principle of present embodiment is: because of side slope 1 has certain gradient, domatic water on it just can flow to the toe direction under action of gravity, in flow process, domatic water is through the sash beam 2 on domatic, because of the end face of sash beam flushes with domatic, current can enter in the groove 2-1 on the sash beam easily, because of being, sash beam 2 is in tilted layout, enter among the sash beam groove 2-1 water just along groove 2-1 to the toe diffluence, enter gutter 3, finally drain, form the drainage system on side slope surface by the gutter.
Embodiment two:
As Fig. 1, shown in Figure 3, the structure of present embodiment, job practices and operating principle are similar to embodiment one, and difference only is that the cross section of groove 2-1 is " U " font.Obviously, the section form of described groove 2-1 is not limited to embodiment one and embodiment two these two kinds of structures, also can adopt other geometries.
