Abstract
The utility model discloses a kind of ecological dam body structure pattern, described dam body is provided with arch top bottom continuous print He coupled, the arch top of described dam body is arranged between two parties on the bottom of described dam body, be provided with multiple uniform steam vent at the arch top of described dam body, be provided with multiple uniform relief hole in the bottom of the described dam body part be positioned at below arch top.Advantage of the present utility model: one is the strong adaptability of current, and flow-shape is very smooth-going, is conducive to the stability of engineering; Two is that the engineering guide functions of this invention is strong; Three is simple process, easy construction; Four is save the energy, saves material; Five is that inner space is comparatively large, is applicable to four large Chinese carp existence.In a word, the utility model can protect beach body from erosion damage, is conducive to again silt and falls to becoming silted up, mould beach volume morphing better, is applicable to beach body protection.
Description
Technical field
The utility model relates to Waterway Regulation technical field, is specifically related to a kind of ecological dam body structure pattern.
Background technology
The Scour and Accretion process that riverbed occurs under river bed change refers to nature situation and after building regulating structure, this Scour and Accretion process always can not be conducive to the activity in production of the mankind, on the contrary, huge destruction may be produced in many cases, therefore engineering measure must be taked to be controlled, namely this kind of engineering measure claims riverbed to renovate, and building used for regulation riverbed, is called riverbed regulating structure.Groynes is modal riverbed regulating structure.
The dam root of groynes connects with riverbank, and abutment stretches to the middle of the river, and the axis of dam or oblique orthogonal with water (flow) direction, forms T-shaped with riverbank in the plane.Groynes is the regulating structure laterally blocked water, and when the non-submerged spur dike of current, the narrow riverbed of its beam, improves flow velocity and wash away shoal; When after current submerged spur dike, then can cause cross current, horizontal training for sediment, increase fairway depth.In addition, groynes can also adjust the split ratio of braided stream, controls shunting, aggradation river shoal, protection riverbank, chooses main flow in case top rushes riverbank and dyke.
Dam body pattern is in the past single longitudinal gradient pattern.Building groynes can converging flow into main channel, protection bunding, but current also can be brought to be separated and the flow phenomenon of the series of complexes such as backflow.Dam body local is as abutment, dam root and flow-shape disorder of bypassing the dam site.Groynes also very easily causes damaged or destroyed by flood.Groynes damaged or destroyed by flood form is broadly divided into abutment damage, dam body damage, dam root damage and integral dam by damage position and damages four classes.Abutment damage mostly is foundation scouring and causes damage, and its general process is foundation scouring---slope failure---, and dam crest caves in.The form of dam body damage is more, and some is that the basis of dam body is washed and causes collapse of dam, and this type of damage form class is similar to abutment damage; Some genus dam facing block stone peels off to roll to lose and forms small gap, then expands again punching and deeply develops into large breach; Also have some to be that current directly wash away downstream slope, cause downstream slope to cave in damage.Dam root damage partly cause is that the sand-pebble of dam root and bank slope joining place is washed and causes and cave in; Some is that dam root section dam facing block stone peels off displacement one by one, forms shallow small gap, is expanded into large breach gradually in the future; Be then that the overflow of dam root place directly washes away footing in addition, basis is damaged by scour.The entirety damage of dam body, multiple local damage factor common combination acts on together often, or caused by single damage repaired in time and expand.Therefore strengthen the impact resistance of groynes, ensure that the stability of himself is very crucial.
Summary of the invention
The utility model provides a kind of ecological dam body structure pattern for solving in known technology the technical problem that exists, and this dam structure is applicable to beach body protection, and beach body can be protected from erosion damage, is conducive to again silt to fall to becoming silted up, and moulds beach volume morphing better.
The technical scheme that the utility model is taked for the technical problem existed in solution known technology is: a kind of ecological dam body structure pattern, described dam body is provided with arch top bottom continuous print He coupled, the arch top of described dam body is arranged between two parties on the bottom of described dam body, be provided with multiple uniform steam vent at the arch top of described dam body, be provided with multiple uniform relief hole in the bottom of the described dam body part be positioned at below arch top.
The diameter of described steam vent is 20cm.
The diameter of described relief hole is 24cm.
Advantage of the present utility model: one) be the strong adaptability of current, flow-shape is very smooth-going, is conducive to the stability of engineering; Two) be that the engineering guide functions of this invention is strong; Three) be simple process, easy construction; Four) be save the energy, save material; Five) be that inner space is comparatively large, be applicable to four large Chinese carp existence.
In sum, the utility model can protect beach body from erosion damage, is conducive to again silt and falls to becoming silted up, mould beach volume morphing better, is applicable to beach body protection.

Fig. 2 is the upward view of Fig. 1;
Fig. 3 is the lateral view of Fig. 1.
Detailed description of the invention
For summary of the invention of the present utility model, Characteristic can be understood further, hereby exemplify following examples, and coordinate accompanying drawing to be described in detail as follows:
Refer to Fig. 1 ~ Fig. 3, a kind of ecological dam body structure pattern, described dam body is provided with arch top bottom continuous print He coupled, the arch top of described dam body is arranged between two parties on the bottom of described dam body, be provided with multiple uniform steam vent 1 at the arch top of described dam body, be provided with multiple uniform relief hole 2 in the bottom of the described dam body part be positioned at below arch top.In the present embodiment, the diameter of described steam vent 1 is 20cm, and the diameter of described relief hole is 24cm.
Although be described preferred embodiment of the present utility model by reference to the accompanying drawings above; but the utility model is not limited to above-mentioned detailed description of the invention; above-mentioned detailed description of the invention is only schematic; be not restrictive; those of ordinary skill in the art is under enlightenment of the present utility model; do not departing under the ambit that the utility model aim and claim protect, can also make a lot of form, these all belong within protection domain of the present utility model.
