Technical Field
The invention belongs to the technical field of river bank drainage, and particularly relates to an integrated kerbstone double-filtration drainage device and a construction method.
Background
Under the ecological river course design trend, more and more river course embankments adopt compound side slopes, set up the level platform of parent above the normal water level, the side slope adopts soft bank slopes such as ecological turf bank protection more above the platform, and the bank slope below the platform is stereoplasm side slopes such as stereoplasm concrete, grout stone. The slope of the turf slope is generally slow, the water coming from the turf slope is slow, but the problems of water flow scouring, water and soil loss, unsmooth drainage and the like exist.
The intercepting ditches are transversely and longitudinally arranged along the berm to perform centralized drainage in the prior art, and if the intercepting ditches are not designed, water and soil loss and muddy water pollution to the berm can be caused if the incoming water directly and oppositely washes the berm, so that the landscape effect is influenced, the operation cost is increased, and the like. If set up special catch basin, the double-walled face of its catch basin all adopts concrete placement, does not filter the rivers that collect, and catch the basin at present and collect all rivers together, carries out the drainage through setting up a drain pipe, can cause rivers drainage unsmooth like this, has impurity in the rivers simultaneously, blocks up the drain pipe easily, forms ponding, increases sanitation personnel's work load, produces serious influence to the river course view.
Disclosure of Invention
The invention aims to provide an integrated kerbstone double-filtration drainage device and a construction method, so that the integrated kerbstone has the function of a cut-off ditch, water flow is subjected to double filtration by arranging a plumbous gabion wall and a first reverse filter layer, the plumbous gabion wall is filtered relative to large-particle soil and sundries in the water flow, the first reverse filter layer is used for filtering sand soil and impurities in the water flow, and the problems of poor river channel landscape, large soil and water cleaning workload and high soil and water cleaning cost caused by the fact that water flow erodes a turf side slope, impurities exist in the water flow and the water flow is not smoothly discharged due to the fact that the water flow washes the turf side slope at present can be solved.
In order to achieve the purpose, the technical scheme adopted by the invention comprises the following steps:
an integrated kerbstone double-filtration drainage device comprises a plumbous silk gabion wall vertically arranged at the slope foot of a turf slope, an integrated kerbstone positioned between the plumbous silk gabion wall and a road surface, a drainage pipe positioned in the integrated kerbstone and a first inverted filter layer covering the drainage pipe;
the vertical height of the lead wire gabion wall is higher than that of the turf side slope, and the lead wire gabion wall and the turf side slope form a first filtering cavity;
the integrated curb comprises an inclined component and a vertical component, wherein one end of the inclined component is connected with the bottom of the plumbous gabion wall 1, the other end of the inclined component is connected with the bottom of the vertical component, and the end, connected with the bottom of the plumbous gabion wall 1, of the inclined component is higher than the end, connected with the bottom of the vertical component, of the inclined component;

In the intercepting drain adopted in the prior art, the double-wall surface of the intercepting drain is poured by adopting concrete, the collected water flow is not filtered, and the condition that sundries in the water flow block the intercepting drain is easily caused; according to the scheme, the lead wire gabion wall is arranged at the slope toe of the turf side slope, when water flows through the turf side slope, large-particle soil and sundries in turf are filtered by the lead wire gabion wall, the water flows can be smoothly collected into the integrated curb, a large amount of large-particle soil and sundries cannot exist in the curb, the workload of sanitation workers is large, and the working efficiency of the sanitation workers is influenced; meanwhile, the water and soil loss of the turf side slope is reduced.
In this scheme, the vertical height that adopts to set up the plumbous silk gabion wall is higher than the vertical height of turf side slope, can effectually avoid under the big condition of turf side slope discharge, rivers directly wander through plumbous silk gabion wall, cause the rivers direct entering integration curb of taking debris.
Secondly in this scheme, still set up first anti-filter layer in integration curb, this first anti-filter layer carries out the secondary filter to the rivers that converge into integration curb, filters littleer sand and soil and impurity in the rivers, when guaranteeing that rivers converge into the drain pipe, can not cause the drain pipe to block up, has also guaranteed that this rivers that converge into the river can not cause the pollution to the river water.
Finally, the inclined direction of the inclined component of the integrated kerb is set, so that water can smoothly flow into the first inverted filter layer when the flow of the water flowing into the integrated kerb is low, and the smoothness rate of the water flow is ensured; the accumulated water in the integrated kerbstone can not be generated, and the serious influence on the river landscape can be generated.
Further, the first inverted filter layer comprises a non-woven geotextile and broken stones; the diameter of the crushed stone is less than or equal to 5 cm; through the first anti-filter layer that nonwoven geotechnological cloth and rubble combine to form, can filter tiny sand and soil and impurity, guarantee the clear and limpid degree of rivers.
Furthermore, the lead wire gabion wall comprises a gabion woven by lead wires mechanically and stones filled in the gabion and having different shapes and sizes; adopt the not consistent stone of shape size, can increase the area of contact of stone in the gabion, increase the area of contact of rivers and stone, reduce the flow area of rivers, guarantee better filtration rivers.
Further, the drain pipe is arranged at the bottom of the vertical component and is obliquely arranged; the drain pipe is arranged at the bottom of the vertical member, the first inverted filter layer covers the drain pipe, the drain pipe is well wrapped, and meanwhile, the bottom surface of the first inverted filter layer is closely contacted with the top surface of the inclined member, and no gap exists; can ensure that when the water flow rate of the water which flows into the integrated kerb is less, the water can also flow into the river through the first inverted filter layer and the water discharge pipe.
Further, the inclination direction of the drainage pipe is the same as that of the turf side slope 4.
Further, the drain pipe adopts
The PVC pipe of (1);
furthermore, the number of the drain pipes is not less than 1, and the drain pipes are arranged at intervals along the river course direction.
In the prior art, a drainage pipe is arranged in a catch basin, so that when the flow of water flow is high, the water flow extends to the road surface to form accumulated water on the road surface; therefore, the adoption sets up a plurality of drain pipes in this scheme can carry out better drainage to the rivers that collect in the integration curb, solves only to set up a drain pipe in the current catch basin, and the drainage of formation is not smooth, probably can make rivers spread to the road surface, forms the problem of road surface ponding.
Further, the interval distance of the drain pipes is 100 cm.
Furthermore, the integrated kerbstone is made of precast concrete; the precast concrete can reduce the construction cost and is simple to manufacture.
