Abstract
The invention relates to the field of hydraulic engineering, in particular to an engineering method for preventing the ditch bank slope from collapsing. The technical scheme of the invention is as follows: water seepage pipes which are parallel to the ditch are respectively buried at two sides of the ditch bank slope, and the burying height of each water seepage pipe is slightly higher than the height of the routine water level of the ditch; a sand filtering layer is wrapped outside each water seepage pipe; the distance between each water seepage pipe and the ditch bank slope at the corresponding side is 5-10m; and a drainage slope between each water seepage pipe and the plane is 0.05-0.3 percent. According to the invention, moisture in soil can be effectively collected and drained by the water seepage pipes buried at two sides of the ditch bank slope, and scouring of seepage waterflow to the ditch bank slope is thoroughly solved. The engineering method provided by the invention has the advantages of scientific and reasonable design, low early-stage once investment, simpleness in construction, low maintenance cost and long-term benefit and is a brand-new engineering method incomparable to the traditional engineering methods.
Description
Technical field
The present invention relates to the hydraulic engineering field, be specifically related to a kind of engineering method that prevents that the stream bank slope from caving in.
Background technology
Draw in the water conservancy construction engineerings such as (row) water, irrigation and alkaline land improving what relate to, the excavation and the maintenance in stream (or claiming the river course) are absolutely necessary.The stream of particularly new excavation is owing to lack the necessary protection measure, usually because the side osmosis of moisture in the soil; Cause stream bank slope earth to cave in; It is stifled to cause the bottom, stream to become silted up, and the lighter influences the discharge capacity in stream, and weight person causes stream forfeiture drain function.Existing for this reason engineering method be the bank slope in the stream carry out revetment or through the plantation vegetation reinforce.Dual mode be to be to block up at all.Wherein, this mode one of revetment is that early investment is big, later maintenance cost is high, the 2nd, be difficult to effect a radical cure the stifled problem of silt that infiltration brings; Channel excavation initial stage plantation vegetation lacks precondition, and promptly bank slope lacks firm soil basis, so vegetation is difficult to survival.
Summary of the invention
The object of the invention is exactly the defective that exists to existing construction technology, and the engineering method that the stream bank slope caves in that prevents that a kind of early investment is few, the later maintenance expense is low, long-term stability is moved is provided.
Its technical scheme is: the embedding soakaway trench parallel with the stream of bank slope both sides difference in the stream, the embedding height of soakaway trench is a little more than the daily height of water level in stream.
Also comprise in the such scheme: said soakaway trench external packets is wrapped with the filter sand layer, and the stream bank slope spacing of soakaway trench and respective side forms the drainage gradient between 0.5-3 ‰ between soakaway trench and the horizontal plane between 5-10 rice.
Soakaway trench at interval 100-300 rice is provided with and observes well and draw the mouth of a river, forms the drainage gradient between 0.5-3 ‰ between every section soakaway trench after at interval and the horizontal plane, draws the mouth of a river and introduces the stream through drainage pipe or introduce among row's ditch vertical with the stream.
Method of the present invention at first adopts " dredging " from design theory; Promptly through being embedded in the soakaway trench of bank slope both sides, stream; Can effectively compile with drainage soil in moisture; Thoroughly solve side and ooze the washing away of stream bank slope, this design has been broken in traditional engineering method and " block up ", and promptly stifled or vegetation is blocked up through revetment.Design science of the present invention thus is reasonable, has once to drop into early stage lowly, and construction is simple, and maintenance cost is few, long-term advantage of being benefited, be the current engineering method incomparable brand-new engineering method.Experiment confirm, its early investment is merely 1/tens of existing revetment method, and after bank slope formed vegetation, later maintenance cost was very little.
Description of drawings
Fig. 1 is the cross-sectional configuration sketch map of an embodiment of the present invention.
The specific embodiment
Below in conjunction with accompanying drawing and embodiment the present invention is done further elaboration.
Embodiment 1, and a kind of engineering method that prevents that the stream bank slope from caving in is the difference embedding soakaway trench parallel with the stream 4 in bank slope 2 both sides in the stream, and the embedding height of soakaway trench is a little more than the daily height of water level 1 in stream.
Embodiment 2, technical at embodiment 1, and said soakaway trench 4 external packets are wrapped with filter sand layer 3, and the spacing a of the stream bank slope 2 of soakaway trench 4 and respective side forms the drainage gradient between 0.5-3 ‰ between soakaway trench 4 and the horizontal plane between 5-10 rice.
Embodiment 3; On the basis of embodiment 2; Soakaway trench 4 100-300 rice at interval is provided with the observation well and draws the mouth of a river, forms the drainage gradient between every section soakaway trench 4 behind the interval and the horizontal plane between 0.5-3 ‰, and drawing-off water is introduced the stream through drainage pipe and perhaps introduced in the externally drained system.
Among the present invention program, soakaway trench can be that bellows or cement ooze pipe, and the size of its caliber is confirmed according to the height of the height of bank slope, gradient, stream day ordinary water level; Observe well and draw being provided with of the mouth of a river according to field condition, as the river course of routine, gutter can 300 meters between left and right at a distance from being provided with, can suitably be provided with flexibly like alkaline land improving according to field piece situation; The drainage gradient can be smooth and easy flows naturally and gets final product to satisfy percolating water; The embedding height of soakaway trench had both considered a little more than the daily height of water level in stream that the following bank slope of the daily water surface generally can not cave in, also be for fear of the river course water reverse osmosis to soakaway trench.
