Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention is further described in detail with reference to the following embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the utility model and are not intended to limit the utility model.
The permeable concrete is added with a certain amount of additive, so that the cohesive force of cement paste and the adhesive force of the cement paste and aggregate are improved, the cement paste cannot block gaps of a concrete lower part structure due to slump, and the gaps are effectively formed, strengthened and uniformly distributed in the integral structure of the permeable concrete. The pervious concrete is prepared by uniformly mixing aggregate broken stones, pervious materials, cementing materials, cement, water and the like according to the definite portions and then paving; the pervious concrete consists of a surface layer and a cushion layer, and after the surface concrete is poured and formed and dried, the transparent sealing agent is coated in about 3 days, so that the durability and the attractiveness are enhanced, and the situation that the pores of the pervious concrete are polluted and blocked after time elapses is prevented.
Example one
As shown in fig. 1-2, in a revetment river bank, a vegetation layer 1, a drainage ditch 2 and a revetment layer 3 are sequentially arranged from a river bank to a river water 4, plants are planted on the vegetation layer 1, the drainage ditch 2 and the revetment layer 3 are formed by pouring and splicing pervious concretes, the revetment layer 3 is in contact with the river water 4, a plurality of planting holes 5 are arranged on the revetment layer 3, and submerged plants are planted in the planting holes 5; plant 5 trapezoidal settings in hole, plant 5 diameter of hole towards 4 directions of river is less than the diameter towards the bank direction, and the benthophyte grows in planting hole 5, because the diameter of planting hole 5 towards 4 directions of river is less than the diameter towards the bank direction, consequently can reduce the washing away of river to earth in planting hole 5, avoids earth to be washed away along with the river.
The upper edge of the drainage ditch 2 is obliquely arranged; the upper edge of the drainage ditch 2 close to one side of the river water 4 is lower than the upper edge of one side close to the river bank. When raining, because the relief height, the rainwater can flow into escape canal 2 along the river bank in, if the rainwater is great for escape canal 2 can't reach the effect of quick drainage, and the rainwater can be followed the lateral wall department of escape canal 2 and spilled over to river 4 direction, thereby flows into in river 4.
The height that escape canal 2 is close to 4 lateral walls of river is less than the height that is close to the bank lateral wall, escape canal 2 is close to the lateral wall and the revetment layer 3 of river 4 and is connected. The lateral walls on the two sides of the drainage ditch 2 are different in height, so that overflowing rainwater can flow to the direction of river water 4 quickly, and rainwater gathering near the river bank is avoided.
The bottom both sides of escape canal 2 are provided with drainage groove 9, drainage groove 9 arranges along the length direction of escape canal 2. If there are impurities in the drainage ditch 2, the water in the drainage ditch 2 can continue to flow along the drainage grooves 9, and the problem of poor drainage caused by the blockage of the impurities can be avoided.
Be provided with blocking structure on the bottom of escape canal 2, blocking structure salient in the bottom surface of escape canal 2, blocking structure blocks silt and debris in the escape canal 2 and flows to downstream direction. The setting of barrier structure can be with following the river bank direction and flow down debris or silt most and block, and when the water in escape canal 2 constantly flowed downstream, debris or silt can be because barrier structure, and the gathering is in barrier structure department, carries out the prefilter to the water in escape canal 2.
One embodiment of the blocking structure is a semicircular body 6, and the semicircular bodies 6 are arranged on the bottom of the drainage ditch 2 in a staggered manner, so that preliminary blocking of sundries or silt in water flow is formed.
Example two
The difference from the above embodiment is that, as shown in fig. 3, the blocking structure is a column 7, the column 7 is in a straight shape, a plurality of columns 7 are uniformly distributed on the bottom of the drainage ditch 2, and the length of the column 7 is equivalent to the width of the bottom of the drainage ditch 2; the cross section of the cylinder 7 is semicircular, trapezoidal or square, and water flowing in the drainage ditch 2 can be primarily blocked and filtered by blocking the cylinder 7 at each stage.
EXAMPLE III
The difference from the above embodiment is that, as shown in fig. 4, the blocking structure is a corrugated body 8, a plurality of corrugated bodies 8 are uniformly distributed on the bottom of the drainage ditch 2, and the total length of the corrugated body 8 after being bent for a plurality of times is equivalent to the width of the bottom of the drainage ditch 2; the cross section of the corrugated body 8 is semicircular, trapezoidal or square.
The blocking structure can also be selected from a circular arc shape according to actual conditions so as to form a block, and the specific shape can be selected according to the implementation mode.
The above-mentioned embodiments are preferred embodiments, it should be noted that the above-mentioned preferred embodiments should not be considered as limitations to the utility model, and the scope of protection of the present invention should be subject to the scope defined by the claims.
