Abstract
The utility model discloses a kind of dam body water draining structure improving loose rock dam shock resistance, comprise dam body, described dam body comprises downstream dam facing, described dam body also comprises a vertical drainage body and a horizontal drainage body, described vertical drainage body is positioned at the axis of dam place of described dam body, one end of described horizontal drainage body is connected with the bottom of described vertical drainage body, its other end extends to described downstream dam facing, and the top of described vertical drainage body is lower than normal pool level, its Bottom Altitude and downstream river course water level adjoining.The utility model by arranging vertical drainage body and horizontal drainage body near the axis of dam; protection enrockment region, downstream; prevent downstream enrockment under seismic damage extreme case to reach capacity state, strengthen the drainage performance of dam body simultaneously, prevent dam body upstream enrockment saturated.
Description
Technical field
The utility model relates to loose rock dam technical field, particularly relates to a kind of dam body water draining structure improving loose rock dam shock resistance.
Background technology
During Rockfill Dam fills, be solve earthworks calculation problem, reach optimal design, time dam body downstream of being everlasting fill slightly poor stockpile.When experience earthquake conditions, the situation such as panel damage, sealing partial failure may be caused, and then form large seepage, may reach capacity at the enrockment in dam body downstream under extreme case, and then threaten safety of dam body.
Utility model content
The utility model mainly to solve in prior art existing technical problem, thus provides a kind of and prevent rockfill area, upstream and rockfill area, downstream is saturated, strengthen the dam body water draining structure of the raising loose rock dam shock resistance of the drainage performance of dam body.
Above-mentioned technical problem of the present utility model is mainly solved by following technical proposals:
The dam body water draining structure of raising loose rock dam shock resistance of the present utility model, comprise dam body, described dam body comprises downstream dam facing, described dam body also comprises a vertical drainage body and a horizontal drainage body, described vertical drainage body is positioned at the axis of dam place of described dam body, and one end of described horizontal drainage body is connected with the bottom of described vertical drainage body, and its other end extends to described downstream dam facing, and the top of described vertical drainage body is lower than normal pool level, its Bottom Altitude and downstream river course water level adjoining.
Further, the both sides of described vertical drainage body are also provided with upstream transition district and downstream transition district, and described downstream transition district is positioned at the top of described horizontal drainage body.
Further, the width of described vertical drainage body and horizontal drainage body is 3-6m.
Further, described vertical drainage body and horizontal drainage body are filled by water discharging body material and form, and described water discharging body material particle size is 30-60cm.
Compared with prior art; the utility model has the advantage of: by arranging vertical drainage body and horizontal drainage body near the axis of dam; protection enrockment region, downstream; prevent downstream enrockment under seismic damage extreme case to reach capacity state; strengthen the drainage performance of dam body simultaneously, prevent dam body upstream enrockment saturated.
Accompanying drawing explanation
In order to be illustrated more clearly in the utility model embodiment or technical scheme of the prior art, be briefly described to the accompanying drawing used required in embodiment or description of the prior art below, apparently, accompanying drawing in the following describes is only embodiments more of the present utility model, for those of ordinary skill in the art, under the prerequisite not paying creative work, other accompanying drawing can also be obtained according to these accompanying drawings.
Fig. 1 is the structural representation of the dam body water draining structure of raising loose rock dam shock resistance of the present utility model.
Detailed description of the invention
Below in conjunction with accompanying drawing, preferred embodiment of the present utility model is described in detail, to make advantage of the present utility model and feature can be easier to be readily appreciated by one skilled in the art, thus more explicit defining is made to protection domain of the present utility model.
Consult shown in Fig. 1, the dam body water draining structure of raising loose rock dam shock resistance of the present utility model, comprise dam body 1, dam body 1 comprises downstream dam facing 2, and dam body 1 also comprises vertical drainage body 3 and a horizontal drainage body 4, and vertical drainage body 3 is positioned at the axis of dam 5 place of dam body 1, one end of horizontal drainage body 4 is connected with the bottom of vertical drainage body 3, its other end extends to downstream dam facing 2, and the top of vertical drainage body 3 is lower than normal pool level 8, its Bottom Altitude and downstream river course water level 9 adjoining.Wherein, vertical drainage body 3 generally adopts vertical slope ratio, also can put slope according to physical condition and arrange.
The both sides of vertical drainage body 3 are also provided with upstream transition district 6 and downstream transition district 7, and downstream transition district 7 is positioned at the top of horizontal drainage body 4.Upstream transition district 6 and downstream transition district 7 are set mainly for the protection of vertical drainage body 3.The width of vertical drainage body 3 and horizontal drainage body 4 is preferably 3-6m.Vertical drainage body 3 and horizontal drainage body 4 are filled by water discharging body material and form, and water discharging body material particle size is 30-60cm, and is evenly distributed, and the fine particle content simultaneously controlling to be less than 0.0075mm is no more than 5%.For preventing the discrete of particle in work progress, every layer is filled and can metal die or other modes be taked to limit in scene.
The utility model by arranging vertical drainage body and horizontal drainage body near the axis of dam; protection enrockment region, downstream; prevent downstream enrockment under seismic damage extreme case to reach capacity state, strengthen the drainage performance of dam body simultaneously, prevent dam body upstream enrockment saturated.
Above, be only detailed description of the invention of the present utility model, but protection domain of the present utility model is not limited thereto, any change of expecting without creative work or replacement, all should be encompassed within protection domain of the present utility model.Therefore, the protection domain that protection domain of the present utility model should limit with claims is as the criterion.
