Abstract
The utility model discloses a hole type flood discharge structure, which comprises an approach channel, wherein the tail end of the approach channel is connected with a contracted section through a control section, a pressure free hole type flood discharge groove section is connected at the tail end of the contracted section, and an energy dissipater is connected at an outlet of the pressure free hole type flood discharge groove section. With the adoption of the technical scheme, the hole type flood discharge groove is adopted to replace the conventional open cut flood discharge groove, and the engineering construction difficulty and the excavated volume are greatly reduced, so that the hole type flood discharge structure is more suitable for complex narrow and steep geologic and topographical conditions.
Description
Technical field:
The utility model belongs to the water delivery engineering technical field, particularly a kind of hole formula flood discharge structure.
Background technology:
Along with The development in society and economy, the water resource demand further strengthens, and hydraulic engineering is faced with complicated geology orographic condition, and engineering arranges that difficulty is big.For in narrow river valley, building high dam, further investigation of earial drainage building and technological innovation are guaranteed the engineering safety operation and are given full play to benefit, seem still for important and urgent.Conventional flood spillway all adopts structure built by opencut method, for the more precipitous landform of two sides massif, can bring high slope to handle, and not only the difficulty of construction of engineering is bigger, and excavated volume is also bigger.
The utility model content:
The technical problem that the utility model will solve is: provide that a kind of difficulty of construction is less, excavated volume is less, be suitable for the hole formula flood discharge structure of complicated narrow, precipitous geology orographic condition, to overcome the deficiency of prior art.
The utility model is to constitute like this: it comprises approach channel 1, and the end of approach channel 1 is connected with contraction section 3 after control section 2, has or not pressure hole formula flood discharging groove section 4 in 3 terminal connections of contraction section, does not have and presses the outlet of hole formula flood discharging groove section 4 to be connected with energy dissipater 5.
Owing to adopted technique scheme; The utility model and prior art are relatively; The utility model adopts nothing to press hole formula flood discharging groove section to replace conventional structure built by opencut method, has significantly reduced engineering construction difficulty and excavated volume, is suitable for complicated narrow, precipitous geology orographic condition more.
Description of drawings:
Fig. 1 is the structural representation of the utility model;
Fig. 2 is the structural representation that the nothing of the utility model is pressed hole formula flood discharging groove section;
Being labeled as of accompanying drawing: the 1-approach channel, the 2-control section, 3-contraction section, 4-do not have the hole of pressure formula flood discharging groove section, 5-energy dissipater.
The specific embodiment:
Below in conjunction with accompanying drawing and embodiment the utility model is further described.
The embodiment of the utility model: the structure of the utility model is as shown in Figure 1; It comprises existing approach channel 1 structure; The end of approach channel 1 is connected contraction section 3 (approach channel 1, control section 2 and contraction section 3 can adopt cut and cover tunneling) after control section 2; Do not have the import of pressing hole formula flood discharging groove section 4 (nothing presses the structure of hole formula flood discharging groove section 4 as shown in Figure 2, and it is the structure of hole shape passage in the country rock) in 3 terminal connections of contraction section, do not having the outlet connection energy dissipater 5 who presses hole formula flood discharging groove section 4.
The embodiment of the utility model is not limited to the foregoing description, and the various variations of under the prerequisite that does not break away from the utility model aim, making all belong to the protection domain of the utility model.
