Description
Ecologically protective permeable dam 0503955
The invention relates to the field of permeable dams, and in particular to an ecologically protective permeable dam.
Background technology
Ecological permeable dam is a kind of artificial dam body built in polluted river by gravel and crushed stone, which is composed of clay rock layers and downstream coagulation zones.
Plants that can purify the water quality are arranged on the dam body, and the sewage can be purified to some extent by combining the principle of rapid infiltration and artificial wetlands principles. Ecological permeable dams are used to treat rural non-point source pollution. In plain areas with small hydraulic gradient and dense river networks, ecological permeable dams are built in reservoirs, lakes and rivers to form a buffer zone in the upstream. In the buffer zone, the sediment and nutritive salts in the water are promoted to settle by prolonging the hydraulic retention time, and at the same time, the nutritive salts are further absorbed and intercepted by large aquatic plants and algae, so as to reduce the content of nutritive salts, inhibit the overgrowth of algae, slow down the eutrophication process, improve the water quality, and have a good protective effect; ecological permeable dam has low construction cost and is widely used in various fields. However, when the permeable dam 1s put into use, because the permeable rock layer is loose, it is easy to fall and collapse due to excessive water pressure, shortening its service life, and over time, the upstream water will have precipitated pollutants, which makes it impossible to block the water flow from the rock layer to the downstream. In addition, when the water overflows the dam, it is easy to bring some suspended matter from the upstream to the downstream with the water flow, which affects the ecological environment of the downstream.
The main objective of the invention is to provide an ecologically protective permeable dam, which can effectively solve the problems in the background technology that the rock layer is easy to fall and collapse due to excessive water pressure, pollutants are blocked, and the downstream ecological environment is affected.
In order to achieve the above objective, the technical scheme adopted by the invention is as follows:
An ecologically protective permeable dam comprises a clay rock layer, and a downstream coagulation zone is fixedly installed on one side of the clay rock layer; the other side of the clay rock layer is fixedly provided with an upstream coagulation zone; a cement pipeline is fixedly installed through the clay rock layer, the downstream coagulation zone and the upstreak}505955 coagulation zone, the downstream coagulation zone is fixedly connected with the upstream coagulation zone through a junction coagulation zone; the outer surface of the upstream coagulation zone is fixedly provided with a fixed ring; an isolation zone is fixedly installed on the upper surface of the upstream coagulation zone; the upper surface of the clay rock layer is planted with vegetation; the lower surfaces of the downstream coagulation zone and the upstream coagulation zone are both fixedly provided with a fixed base.
Preferably, a downflow reinforcing mesh is fixedly installed inside the downstream coagulation zone; an upstream reinforcing mesh is fixedly installed in the upstream coagulation zone.
Preferably, the interior of the cement pipeline is filled with a rock zone, and both ends of the cement pipeline are fixedly provided with steel wire meshes.
Preferably, a junction reinforcing mesh is fixedly installed inside the junction coagulation zone, and both ends of the junction reinforcing mesh are fixedly connected with the downflow reinforcing mesh and the upstream reinforcing mesh respectively.
Preferably, a transmission rod is movably installed in the middle of the fixed ring; the lower end of the transmission rod is fixedly provided with a nylon brush; the upper end of the transmission rod is fixedly provided with a pull ring.
Preferably, both side surfaces of the isolation zone are fixedly provided with fixed piles; the lower end of the fixed pile is fixedly provided with an embedded block; an isolation net is embedded in the middle of the isolation zone; the lower surface of the isolation net is fixedly provided with a junction block.
Preferably, the surface of the fixed pile is provided with four groups of fixed screw holes.
Compared with the prior art, the invention has the following beneficial effects:
In the invention, the arranged cement pipeline can fix the loose rock zone by matching with the steel wire mesh when in use, so that the rock zone can be prevented from crashing when the water pressure is high, and the cement pipeline has good stability, under the force of the transmission rod and the pull ring, the arranged nylon brush can bring the dust and some domestic wastes deposited at the bottom layer to the surface layer to be cleaned with the water flow, so as to prevent the blockage of the barbed wire opening, thus achieving a good cleaning effect. The isolation zone can block some floating objects impacted from the upstream during use, and it can be cleaned by the staff to prevent it from entering the downstream and affecting the ecology, thus playing a better role in environmental protection.
