Abstract
The utility model provides a consequent slope mountain-by-mountain channel structure, be the closed reinforced concrete channel of rectangle including the cross-sectional area, closed reinforced concrete channel is arranged in proper order and is connected gradually along channel axis direction, and slope body department excavation of every section closed reinforced concrete channel both ends downside has cushion cap settling area, closed reinforced concrete channel canal body both ends are all fixed to be settled on the cushion cap of both ends downside, establish the expansion joint between canal body and the canal body. The conditions that the overall stability of a natural side slope of a mountain-climbing channel is poor, the slope gradient is large, the channel stability is poor due to geological conditions such as the direction of a channel axis and a rock stratum forward slope, management is inconvenient, the later-period operation cost is increased and the like are avoided. Belongs to the field of mountain-by channels in hydraulic engineering.
Description
Technical Field
The utility model relates to a consequent slope mountain-climbing channel structure belongs to the mountain-climbing channel field among the hydraulic engineering.
Background
The existing channel structure is mainly based on actual topography survey, different structure types are used according to different topography and geological conditions after a channel line is determined, the structure types mainly comprise trapezoidal, rectangular, U-shaped and composite structure types, a plurality of rectangular section types and stone-building trapezoidal sections are adopted in mountainside channels, but the existing channel structure type is easy to destabilize integrally by adopting the original structure type aiming at the topography conditions that the channel side slope stability is poor, the intersection angle between the channel axis and the rock stratum trend is small (namely a forward slope) and the like.
Disclosure of Invention
The utility model provides a consequent slope mountain-by-mountain channel structure: the situations of inconvenient management, increased later-period operation cost and the like caused by poor channel stability due to geological conditions such as poor integral stability of natural side slopes of mountain-by-pass channels, large slope gradients, small intersection angles between channel axes and the trend of rock strata (namely, a forward slope) and the like are avoided.
In order to solve the problems, the forward slope mountain-climbing channel structure comprises closed reinforced concrete channels with rectangular cross sections, the closed reinforced concrete channels are sequentially arranged along the axis direction of the channels and are sequentially connected, bearing platform arrangement areas are excavated at the slope body positions on the lower sides of the two ends of each section of closed reinforced concrete channel, bearing platforms are fixedly arranged at the bearing platform arrangement areas, and the two ends of each closed reinforced concrete channel are fixedly arranged on the bearing platforms on the lower sides of the two ends.
In the forward slope mountain-side channel structure, a steel plate is embedded at the upper end of the bearing platform, and the steel plate is transversely laid between the bearing platform and the closed reinforced concrete channel;
in the forward slope mountain-side channel structure, an expansion joint is arranged between two adjacent closed reinforced concrete channels, and a rubber water stop is embedded at the expansion joint along the circumferential direction;
in the forward slope mountain-side channel structure, a bearing platform is arranged at the lower side of the butt joint end of two adjacent closed reinforced concrete channels, and the butt joint ends of the two closed reinforced concrete channels are erected and arranged at the upper end of the bearing platform.
Compared with the prior art, the channel of the utility model does not need to be excavated along the axis of the channel, the channel only carries out local excavation on the position of the bearing platform, the conditions of cutting feet in the steep slope and the consequent slope are reduced, the excavation quantity of the whole channel is reduced, the conditions of instability in excavation and the like are avoided, the integral stability of the whole channel can be better controlled, and the closed rectangular section type can well avoid the upper rock masses of mountain-by-mountain channels from weathering and falling off and the surrounding branches and leaves from causing the silting of the channel in the operation process; the investment required by the structure size determined according to the structure settlement is saved compared with other types; the requirements of small occupied area, high safety, economy, practicality, difficult pollution of water flow and the like are met to a great extent.

Detailed Description
To further clarify the objects, technical solutions and advantages of the present invention, a more particular description of the invention will be rendered by reference to the appended drawings, which are illustrated in the appended drawings.
Examples
Referring to fig. 1 and 2, the embodiment provides a forward slope mountain-climbing channel structure, which includes a closed reinforced concrete channel 1 with a rectangular cross-sectional area, the closed reinforced concrete channel 1 is sequentially arranged along the channel axis direction and is sequentially butted, a bearing platform placing area is excavated at the slope body at the lower side of the two ends of each section of the closed reinforced concrete channel 1, the bearing platform placing area is excavated according to the terrain and geological conditions to avoid the cutting condition, a bearing platform 2 is arranged at the bearing platform placing area, a steel plate 3 is pre-embedded at the upper end of the bearing platform 2, the steel plate 3 is transversely laid between the bearing platform 2 and the closed reinforced concrete channel 1, the concrete construction is to pour and pre-embed the bearing platform 2 and the pre-embedded steel plate 3 after the excavation of the bearing platform foundation is completed, then the upper structure pouring construction is carried out, the excavation of the slope at the rest parts can not be carried out during the period, the two ends of the closed reinforced concrete channel 1 are fixedly arranged on, an expansion joint 4 is arranged between two adjacent closed reinforced concrete channels 1, a rubber water stop belt is embedded at the position of the expansion joint 4 along the circumferential direction, as shown in figure 1, a bearing platform 2 is arranged on the lower side of the butt joint end of the two adjacent closed reinforced concrete channels 1, and the butt joint end of each of the two closed reinforced concrete channels 1 is erected and arranged at the upper end of the bearing platform 2.
The channel is in a closed type, traffic can be used as a traffic channel through the top of the channel during operation, for example, the channel is steep and the forward slope section is longer, and a manhole can be arranged at the top of the channel according to actual conditions for convenience in later operation management.
The above description is only exemplary of the present invention and should not be taken as limiting the scope of the present invention, as any modifications, equivalents, improvements and the like made within the spirit and principles of the present invention are intended to be included within the scope of the present invention.
