Abstract
The invention discloses a method for treating the drifting of sandbars and relates to a river treatment technology. The sandbars of different sizes in the river drift backwards along with the flushing of the river water so as to cause migration of buildings and fields and the like on the sandbars; and the sandbars drift leftwards and rightwards so as to cause drifting of the sandbars towards the main navigation channel and further influence the navigation of a ship. The technical scheme of the invention is as follows: a plurality of baffles are inserted into the front end as well as the left side and right side at the front end of the sandbars, so that the problems of drifting backwards, leftwards and rightwards of the sandbars and the like are solved.
Description
Technical field
The present invention relates to the river management technology.
Background technology
The shoal that differs in size is arranged in rivers, because the unstability that the factors such as the flow direction of the size of current, water have caused river to flow, shoal can produce the drift of two kinds of forms: first kind, it is drift backward, the front end of shoal (being the direction that river washes away), under the impact of river, silt constantly runs off; The rear end of shoal then is that silt is constantly increasing.This consequence can cause building on the shoal, field, forest etc. constantly with moving behind the shoal and move.Second kind, it is left and right drift, this also is because the not influence of equal factor of the size of river, the flow direction, current wash away the left side (or right side) of shoal unevenly, caused shoal (or left) drift to the right, this consequence can cause the change in river course, particularly shoal can influence the navigation of boats and ships when the main channel drift.
Summary of the invention
The objective of the invention is: propose a kind of method of administering the shoal drift.
The technical solution adopted in the present invention (or its design principle) is: insert several plate washers (as Fig. 1) at the front end of shoal and the left and right side of front end, this plate washer in the river surface part, is gone into the river bed from the river surface straight cutting; In the shoal part, also insert the same degree of depth.Just constitute a groove between two plate washers, when river rushes at shoal, be entrained in the silt in the river, just " filling out " goes in the groove.Shown in the figure one be plate washer when just having inserted silt " fill out " situation when going into groove; It shown in the figure two situation that silt " is filled out " has expired groove.When silt " fill out " expired groove after, the silt of Liu Ruing is just dirty with river again.
Characteristics of the present invention are: because the effect of plate washer is arranged, shoal is drift backward neither, also can left and right sides drift.
Description of drawings
Fig. 1 is: one of schematic diagram is vertical view (silt when plate washer has just inserted " is filled out " situation when going into groove).
Fig. 2 is: two of schematic diagram is vertical view (silt " is filled out " situation behind the full groove).
Fig. 3 is: the schematic diagram of specific embodiment is vertical view.
Among the figure: (1) shoal; (2) plate washer; (3) support frame plates; In addition,---→ be current and water (flow) direction.
The specific embodiment
3 this embodiment is described in conjunction with the accompanying drawings.Insert several plate washers (2) at the front end of shoal and the left and right sides of front end, this plate washer (2) in the river surface part, is gone into the river bed from the river surface straight cutting, can insert under the river bed 0.2-1.00 meters again; In the shoal part, insert the same degree of depth too.Just constituted a groove between two plate washers (2), several plate washers (2) have just constituted several grooves.The width of each plate washer (2) is between 0.2-1.00 meters, and length is between 1-10 meters.Front end at shoal also has a support frame plates (3), equally also is to go into the sandy soil from the Shamian Island straight cutting, 1-5 meters of its degree of depth; The degree of depth perhaps suitable and plate washer inserts.This support frame plates (3) is connected with each plate washer (2).Like this, when water slug plate washer (2), because the effect that has plate washer (2) to be connected with support frame plates (3), plate washer (2) just is unlikely to be dashed dilapidatedly by water.
Therefore, can consider form, plate washer (2) is cast in support frame plates (3) with steel concrete.Certainly, during construction, at first dig out deep trouth, the following and left and right sides of deep trouth is kept apart with sheet material (plank, pigment plate etc.), forms the space, and the reinforcing bar of weaving in the space again is poured into concrete at last.
Claims (4)
1. a method of administering the shoal drift comprises plate washer (2), support frame plates (3), it is characterized in that: insert several plate washers (2) at the front end of shoal and the left and right side of front end, and be several; Insert support frame plates (3) simultaneously.
2. the method for improvement shoal according to claim 1 drift is characterized in that: plate washer (2), in the river part, go into the river bed from the river surface straight cutting; In the shoal part, also insert the same degree of depth.
3. the method for improvement shoal according to claim 1 drift is characterized in that: support frame plates (3), at shoal, insert the sandy soil from Shamian Island.
4. the method for improvement shoal according to claim 1 drift is characterized in that: each plate washer (2) is connected with support frame plates (3).
