The invention is suitable for retaining waste debris in large-size and medium-size debris fields in hydraulic and hydroelectric engineering.
Description
Technical field
The present invention relates to pushing off the slag structure and the job practices thereof of a kind of Tu Shizhachang, be applicable to that the waste of big-and-middle-sized Hydraulic and Hydro-Power Engineering Tu Shizhachang is blocked.
Background technology
Produce a large amount of native rock ballasts in the development & construction project construction process, the wastes of blocking such as barricade (dry stone wall, stone masonry or concrete), reinforced gabion are set below the slag field usually.Not only draw materials require high, investment is big, and since barricade or reinforced gabion outward appearance with the view contrast is bigger on every side, unfavorable environmental protection.
Summary of the invention
The technical problem that the present invention will solve is: to the problems referred to above, a kind of convenience of drawing materials, reduced investment, native rock ballast field pushing off the slag structure that landscape effect is good are provided, and provide the job practices of this structure.
The technical scheme that the present invention adopted is: the pushing off the slag structure of a kind of Tu Shizhachang; This structural configuration is peripheral in native rock ballast field; It is characterized in that: this pushing off the slag structure comprises the drainage blanket that is layed on the severely-weathered layer in ground; Above the drainage blanket by take from the said native rock ballast field, the cubic meter of stone is not less than 60% the slag pushing off body that material forms through layered rolling of abandoning, its cross section is trapezoidal; Domatic upper berth, the said slag pushing off body upper reaches has thickness to be not less than the loaded filter of 50cm, and toe place, slag pushing off body downstream is provided with planting groove, and planting in the groove has plant.
The up stream slope ratio of said slag pushing off body is not more than 1: 1, and the slope, downstream is than being not more than 1: 1.5.
The job practices of above-mentioned pushing off the slag structure may further comprise the steps:
A) planning to build the ground of making pushing off the slag structure place, the covering layer of removing the surface digs down and forms a recessed base surface to severely-weathered layer;
B) in base surface, lay gravel and rubble, form drainage blanket;
C) abandon material in the screening native rock ballast field, require its cubic meter of stone to reach more than 60%;
D) the said material of abandoning of layered rolling, the slag pushing off body of formation trapezoid cross section;
E) establish the thick loaded filter of 50cm at least on domatic upper berth, the slag pushing off body upper reaches;
F) the excavation planting groove at toe place, slag pushing off body downstream is planted in the groove and is gone up plant.
In the step d), the said thickness layered rolling of abandoning material by every layer of 60～80cm.
The invention has the beneficial effects as follows: 1) main material of construction slag pushing off body is the material of abandoning in the native rock ballast field, draw materials conveniently, and reduced investment, and reduced the true reactor quantity of slag of slag field.2) slag pushing off body is rock structure and is provided with planting groove, plants in the groove and goes up plant, has improved the outward appearance of slag pushing off body, is beneficial to environmental protection.
Description of drawings
Fig. 1 is the elevation of embodiment of the invention band section.
Fig. 2 is the vertical view of the embodiment of the invention.
The specific embodiment
Like Fig. 1, shown in Figure 2; Present embodiment pushing off the slag structural configuration is in the periphery of native rock ballast field 8; It comprises the drainage blanket 2 that is layed on the severely-weathered layer in ground; Be provided with the slag pushing off body 4 of trapezoid cross section above the drainage blanket 2, this slag pushing off body is to be formed by material 3 (requiring its cubic meter of stone the to be not less than 60%) layered rolling of abandoning in the said native rock ballast field.There is rubble loaded filter 5 on domatic upper berth, the upper reaches of slag pushing off body 4, and the thickness of loaded filter generally is not less than 50cm.In order to improve the slag pushing off body outward appearance to utilize environmental protection, the toe place also is provided with planting groove 6 in the slag pushing off body downstream, serike 7 (be generally and climb up by holding on to plant) in the groove.
In addition, for guaranteeing the structure steadiness of slag pushing off body 4, the up stream slope ratio of general requirements slag pushing off body is not more than 1: 1, and the slope, downstream is than being not more than 1: 1.5.
The job practices of present embodiment is following:
A) planning to build the ground of making pushing off the slag structure place, removing its surperficial covering layer to severely-weathered layer, digging down and form a recessed base surface 1 (the foundation excavation line 1-1 that outmost two lines are respectively upstream and downstream among Fig. 2);
B) in above-mentioned base surface 1, lay gravel and rubble, form drainage blanket 2;
C) abandoning in the native rock ballast of the screening field expects 3, requires the cubic meter of stone to reach more than 60%;
D) abandon material by what 60～80cm thickness layered rolling filtered out, form the slag pushing off body 4 of trapezoid cross section, and will guarantee that the up stream slope ratio of slag pushing off body is not more than 1: 1, the slope, downstream is than being not more than 1: 1.5;
E) lay the rubble loaded filter 5 that 50cm is thick at least in the slag pushing off body upstream side, loaded filter part is overlapping with native rock ballast field 8, as the loaded filter hemline 5-1 among Fig. 2 be pressed in Tu Shizhachang below; The downstream hemline 8-1 of Tu Shizhachang is positioned at the vertical direction at loaded filter 5 middle parts.
F) the excavation planting groove 6 at toe place, slag pushing off body downstream, the planting groove cross section is for trapezoidal, and Fig. 2 middle and upper reaches side is the excavation sideline 6-1 of planting groove, and the downstream is planting groove cell wall 6-2.Plant 7 is climbed up by holding on in plantation in the planting groove.
