Abstract
The utility model discloses a large-gradient gravel rive bank protection structure comprising a bank protection structure and a protection apron, wherein the bank protection structure is vertically arranged, the protection apron is horizontally arranged, and the bank protection structure is vertically connected with the protection apron; the bank protection structure is a right-angled trapezoidal; the lower part of the bank protection structure is provided with a connection trough used for connecting the protection apron; one end of the protection apron is clamped in the connection trough; the distance between the lower end of the opening of the connection trough and the bottom surface of the bank protection structure is 0.5m. For the protection structure, the overall impact resistance is obviously strengthened, the protection structure can effectively avoid invasion of water flow on the bottom of a river bank; the overall stability is improved, the situations of breakage, displacement and the like are not easy to cause, so that the bank walls at two sides and a riverbed can be protected, but also the self protection structure can also be prevented from being damaged.
Description
Technical field
The utility model relates to the safeguard structure in riverbed, is specially the safeguard structure that riverbank, ovum gravel river falls in a kind of big ratio, belongs to river regulation hydraulic engineering technical field.
Background technology
In China's western mountainous areas many such rivers are arranged: bigger than falling (generally greater than 1%), riverbed are made up of the ovum gravel and ovum gravel covering layer thicker (being generally more than the 5m), flow velocity are bigger, so that its flow turbulence is strong, scour is very competent, that adds riverbed and riverbank can be relatively poor towards property, is easy to cause water front construction (flood wall, littoral highway etc.) damaged or destroyed by flood.
The erosion control structure that uses in river regulation at present mainly contains galvanized wire cage, shallow foundation groynes and soft raft etc.The galvanized wire cage is to be formed by cage of reinforcement and iron wire braiding; in practice, generally to stack two-layerly, first floor is deposited on the bed surface; the second layer is deposited under the bed surface; but because second layer galvanized wire cage river bottom protection width is less than normal, current easily wash away the outward flange of the second layer; cause subsiding of galvanized wire cage; and first floor galvanized wire cage is positioned on the riverbed, and end face is overcurrent not, makes it more limited to the protective effect on riverbank like this.Shallow foundation groynes and for example, it be when construction with foundation excavation after projected depth, build the groynes mask again, this shallow foundation groynes is applicable to that mainly the river course groundwater table is low, foundation excavation is the section easily, because its abutment scour depth is bigger, buried depth is darker, and it is poor to cause washing away the back self stability.Though the soft raft shock resistance is better, but because ease of connection each other loosening fracture in soft raft inside particularly when water impact is strong, will cause large-area destruction in case fracture takes place, and impact the downstream with river, cause bigger accident.
The utility model content
At the prior art above shortcomings, the purpose of this utility model is to provide that a kind of anti-impact force is strong, the river riparian protection structure of good stability.
The technical solution of the utility model: greatly than falling ovum gravel river riparian protection structure, it is characterized in that comprise bank protection structure and protection-apron, described bank protection structure vertically is provided with, protection-apron is horizontally disposed with, and bank protection structure is connected with protection-apron is vertical; Described bank protection structure is a right-angled trapezium, is provided with the link slot that is used to connect protection-apron in the bottom of bank protection structure, and an end of protection-apron is connected in the link slot.
Further, the spacing between the open lower end of described link slot and the bank protection structure bottom surface is 0.5m.
With respect to prior art, the utlity model has following beneficial effect:
1, the whole anti-impact force of shore protection obviously strengthens, and by the bank protection structure of straight wall type is set, makes current slow down washing away of shore protection, can effectively avoid the draw brush effect of current to the bottom, riverbank;
2, the resistance to overturning of safeguard structure is improved, because bank protection structure and protection-apron adopt and rectilinearly be connected and be reinforced concrete structure, is not easy to rupture, situation such as displacement, not only can protect the both sides bulkhead wall, and the while can also prevent from self to be damaged.
Description of drawings
Fig. 1 is the structure sectional view of the utility model safeguard structure;
Fig. 2 is the structure sectional view of the another kind of embodiment of the utility model.
Among the figure, 1-bank protection structure, 2-protection-apron, 3-link slot, 4-riverbed.
The specific embodiment
The utility model is described in further detail below in conjunction with the drawings and specific embodiments.
As shown in Figure 1, ovum gravel river riparian protection structure falls in a kind of big ratio, comprise bank protection structure 1 and protection-apron 2, described bank protection structure 1 is right-angled trapezium and vertical the setting, protection-apron 2 is the rectangular block shape structure and is horizontally disposed with, right-angle side bottom at bank protection structure 1 is provided with link slot 3, and the spacing between the open lower end of link slot 3 and bank protection structure 1 bottom surface is 0.5m, realizes in the link slot 3 being connected with bank protection structure 1 thereby an end of protection-apron 2 is connected to.
When safeguard structure of the present utility model was installed, bank protection structure 1 was fixed on the both sides, river course, and protection-apron 2 is fixed on the riverbed.Bank protection structure 1 highly is 3～5m usually, excavate downwards from the riverbed earlier before installing to the degree of depth that bank protection structure 1 can be set, re-lay bank protection structure 1, the riverbed of backfill part then, when reaching the aperture position of link slot 3, lay protection-apron 2 again in the riverbed, the thickness of protection-apron 2 is generally about 10cm, its width is decided according to the channel protection demand, fixes at casting cement more at last.
Referring to Fig. 2, in the utility model, bank protection structure 1 can also be a rectangular configuration, and link slot 3 is set on the limit of its vertical direction, then bank protection structure is fixed on the both sides, river course.
When safeguard structure is set, for the curve that adapts to the river course and consider bulking effect, normally with safeguard structure along the river the road water (flow) direction be provided with at interval, the length of every section safeguard structure is about 12m, reserve the flexible settlement joint of 2～5cm between safeguard structure at interval, flexible settlement joint is filled with pitch or other water-repellent substances.
Need to prove at last, above embodiment is only in order to illustrate the technical solution of the utility model but not the restriction technologies scheme, although the applicant has been described in detail the utility model with reference to preferred embodiment, those of ordinary skill in the art is to be understood that, those are made amendment to the technical solution of the utility model or are equal to replacement, and do not break away from the aim and the scope of the technical program, all should be encompassed in the middle of the claim scope of the present utility model.
