Abstract
The utility model discloses a side slope drainage and protection structure, and belongs to the technical field of hydropower station foundation engineering. The side slope drainage and protection structure comprises a transverse catchwater dug under a side slope, a catchwater bottom plate paved at the bottom surface of the catchwater, and catchwater sidewalls arranged on two side walls of the catchwater, wherein one side, away from the side slope, of the catchwater is provided with a barricade, the top surface of the barricade is higher than the upper edge surface of the catchwater, and a plane with certain width is reserved between the catchwater and the barricade and is provided with a hardened layer. According to the technical scheme, the catchwater structure is arranged at the opening of a gully of the side slope, so running water and sundries from the gully can be effectively dispersed, in addition the barricade higher than the catchwater is arranged for further protection and isolation, and infrastructures under the side slope are enabled not to be damaged and polluted by sewage and the sundries flowing out of the gully of the side slope.
Description
Technical field
The utility model belongs to power station Foundation Design technical field, relates to gutter and the safeguard structure thereof at the side slope coombe exit or entrance of a clitch, a kind of power station, specifically relates to a kind of slope drainage and safeguard structure.
Background technology
Build among mountain more in the power station of China, and in construction period, engineering troop is stationed, and often has the infrastructure such as a lot of houses, warehouse, equipment and need to build or be parked near the region, level land of side slope.Through rain drop erosion year in year out, side slope face often can form either large or small coombe.Due to the formation complexity of coombe, in the time meeting with heavy rain and flood, generally all with the multiple foreign material such as silt, rock ballast, all converge in coombe under row, and flowing velocity is fast, impact force is large, easily damages being arranged near the infrastructure such as warehouse, house and power plant building the side slope coombe exit or entrance of a clitch, and surrounding enviroment are polluted.And general gutter is difficult to effectively evacuate the foreign material that side slope coombe is gone out, and easily alluvial, not easy to clean.
Utility model content
In order to address the above problem, the utility model provides a kind of slope drainage and safeguard structure, has reached the filth-discharging effect that intercepts water preferably.
The utility model is achieved by following technical solution.
A kind of slope drainage and safeguard structure, the catchwater abutment wall that is included in the horizontal catchwater excavating under side slope, the catchwater base plate that is laid on catchwater bottom surface and is arranged at catchwater two side, establish barricade at described catchwater away from side slope one side, the end face of described barricade is higher than gutter top edge face, between described catchwater and barricade, leave the plane of certain width, and establish hardened layer in this plane.
Described barricade is concrete structure, and its end face exceeds the top edge face 1.2～2m of catchwater.
Plane width between described catchwater and barricade is 0.6～1.2m; Between described catchwater and side slope, be provided with the passage that width is 1.5～3m.
The beneficial effects of the utility model are:
A kind of slope drainage described in the utility model and safeguard structure, by arrange catchwater structure at side slope coombe exit or entrance of a clitch place, can effectively evacuate flowing water and foreign material from coombe, and arrange and further protect and isolate higher than the barricade of catchwater, reached the effect that ensures the sewage foreign material damage and pollution that under side slope, each infrastructure is not overflowed by catchwater; Once catchwater in service invention alluvial can be cleared up by desilting equipment on the reserved passage in both sides, gutter, is convenient to Maintenance and Repair, and not can with live greening and the mutual interference of operational management phase in region under side slope; In addition, in the time occurring compared with great flood, barricade exceeds the structure of catchwater, has greatly increased the sectional area of drainage section, and drainability increases, and has improved its protection effect to the infrastructure such as warehouse, house of arranging on side slope lower platform.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
In figure: 1-catchwater, 2-catchwater abutment wall, 3-catchwater base plate, 4-hardened layer, 5-barricade, 6-side slope.
Detailed description of the invention
Further describe the technical solution of the utility model below in conjunction with accompanying drawing, but described in claimed scope is not limited to.
As shown in Figure 1, a kind of slope drainage described in the utility model and safeguard structure, be included in the horizontal catchwater 1 of 6 times excavations of side slope, be laid on the catchwater base plate 3 of catchwater 1 bottom surface and be arranged at the catchwater abutment wall 2 of catchwater 1 two side, establish the barricade 5 of concrete structure at described catchwater 1 away from side slope 6 one sides, the end face of described barricade 5 is higher than gutter 1 top edge face 1.2～2m, between described catchwater 1 and barricade 5, leave the plane that width is 0.6～1.2m, and in this plane, establish hardened layer 4, as walkway, between described catchwater 1 and side slope 6, establish the passage that width is 1.5～3m simultaneously, as equipment and the artificial channel of later stage desilting, strengthened appearance water sectional area simultaneously, in the time having super large flood and mud-rock flow to attack, can possess stronger drainability.
The material of catchwater base plate 3 and catchwater abutment wall 2 can be the plain concrete of C15～C20 strength grade, also can adopt stone masonry, but surface need adopt ordinary mortar to wipe one's face after stone masonry completes, gutter base plate 3 thickness 0.2～0.4m, gutter abutment wall 2 thickness 0.3～0.5m; Hardened layer 4 adopts the plain concrete construction of C15～C20 strength grade, thickness 0.2～0.5m; Barricade 5 adopts the plain concrete construction of strength grade >=C20, and cross section is the right-angled trapezium of the thick 0.3～0.5m in top, is slope away from catchwater 1 one sides, and slope is than 1:0.1～1:0.5.
When construction:
First,, along side slope 6 bottom transverse excavation catchwaters 1, then carry out the construction of catchwater base plate 3 and catchwater abutment wall 2; Then carry out concrete guard wall 5 and construct, last plane reserved between barricade 5 and catchwater 1 is laid hardened layer 4, and the plane between smooth catchwater 1 and side slope 6, completes construction.
Embodiment of the present utility model is not limited to above-described embodiment, within the various variations of making under the prerequisite that does not depart from the utility model aim all belong to protection domain of the present utility model.
