Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the utility model is further illustrated.
As shown in Figure 1 to Figure 4, the combining structure of blocking of protecting for ditch water treatment and mud-rock flow of protecting for ditch water treatment and mud-rock flow described in the utility model, comprises checkdam 1 and the draining pipe culvert 2 be communicated with downstream river course checkdam 1 upper river; Also comprise interception dam 3, described interception dam 3 is positioned at the upstream of checkdam 1, and the one end on interception dam 3 is connected with edge, river course 4, and the other end extends in river course.Wherein the effect of checkdam 1 and draining pipe culvert 2 realizes the stop to cheuch river, for downstream provides temporary construction region; And the effect of tackling dam 3 is the solid matters for tackling in river, realize solid water shunting simultaneously.As the interception to mudstone when there is mud-rock flow, avoiding it directly to impact checkdam 1 place, therefore can reduce the percussion of mudstone to checkdam 1, and avoid mudstone to cause blocking to draining pipe culvert.
General, be respectively arranged with at least one interception dam 3 in both sides, river course, to make along on direction, river course, to the whole cross section in river course all there being corresponding interception dam dam body; Certainly, the concrete quantity of tackling dam 3 can set according to actual conditions.Usually, when being provided with multiple interception 3, what generally multiple interception dam 3 can be interlocked successively along the river course flow direction is arranged on both sides, river course; As shown in fig. 1.After being blocked by interception dam group multistage, mudstone solids reduces step by step, substantially can eliminate the harm of mud-rock flow to checkdam 1 when reaching checkdam 1 place.
In addition, the spacing a between adjacent two interception dams 3, generally according to actual conditions setting, spacing a is excessive, boundary of works area can be caused comparatively large, increase difficulty of construction; And spacing a is too small, then can reduce the blocking effect to mudstone.In addition, according to actual conditions, generally the spacing a between adjacent two interception dams 3 can be arranged equal or flow to direction spacing a along river course and reduce gradually; When being wherein set to flow to along river course the situation that direction spacing a reduces gradually, in the good situation of guarantee blocking effect, the distribution distance that interception dam 3 flows to along river course can be shortened as far as possible, can boundary of works area be shortened, reduction difficulty of construction.
In addition, general interception dam 3 comprises and stops section 31, and in order to ensure blocking effect, the section of stop 31 is flowed to vertical setting with river course, and as shown in fig. 1, will stop that one end of section 31 is connected with edge, river course 4, the other end extends in river course.On this basis, further, also can arrange the section of blocking 32, described stop section 31 and the section of blocking 32 connect into " L " shape; And described in the section of blocking 32 one end with stop section 31 on the one end extended in river course be connected, the section of blocking 32 other end extends towards upstream, river course.The effect of the section of blocking 32 mainly avoids the solid matters such as mudstone from stopping that the free end of section 31 flows out, and can strengthen the interception result of the 3 pairs of mudstones in interception dam.
