Description

A kind of town and country river course slope protection system
Technical field
The invention belongs to town and country river regulation field, more particularly to a kind of town and country river course slope protection system.
Background technology
At present, new socialist countryside is the strategic decision of one, China.In the past few years, constantly pushing away with new countryside construction Enter, town and country assume an entirely new aspect, and regional economic development and living standards of the people are substantially improved.China's water resource enriches, many Regional water system is in great numbers, and river is numerous.It is new for the long-acting management socialism that is distributed in the town and country river course such as village, small towns on a large scale One vital task of rural development.The long-acting management in town and country river course, it is related to able to resisting flood and drought, environmental protection, water body safety and water conservancy The content of many aspects such as engineering application, to carry out this work, it is necessary to the cooperation of multiple departments of government and all sectors of society with Coordinate;The long-acting management work in town and country river course is carried out, is preserved the ecological environment, maintains natural equilibrium, promotes human society and natural ring The inevitable choice of border harmonious development.
With the enhancing of environmental consciousness, the theory of ecological revetment gradually forms, in order to fully demonstrate the design of ecological revetment Theory, on the basis of safety and stability is met, bank protection structure will consider to be advantageous to the growth of river course aquatic animal, plantses, profit as far as possible Decomposed with the aquatic animals and plants in river course or absorb pollutant, and then play the catharsis to water body.Ecological revetment It is the artificial shore protection with conservation of nature, it can reduce shore protection pollutant and enter the pollutant between river course, have again certain Bank protection effect and flood fighting effect.
Shore protection mainly uses following scheme at present:
Scheme one, geotechnological grid grassed slope, it has low cost but is easily stored destruction and biological damage, antiscour by people Ability;Scheme two, pitched work, including dry stone pitching and stone masonry bank protection, pitched work are typically gathered materials on the spot, fully profit With local resources, because block stone rough surface is uneven, is rubbed between water body big, certain wave damping effect, this kind can be played Slope protection plan does not apply to mechanically actuated, is influenceed greatly by local material, building stones size, and bank protection thickness difficulty or ease are guaranteed, stone masonry Will be domatic completely enclosed, completely cut off domatic contacting between water body, ecology and landscape effect are poor, and it is big that the program has difficulty of construction With the construction period it is long the problems such as;
The prefabricated interlocking segment bank protection of scheme three, concrete, cost is high, but good integrity, and intensity is high, and itself is influenceed by stormy waves current It is small, can mechanized construction, but to levee slope deform adaptability it is poor;
Scheme four, non-fine concrete grass planting bank protection, using concrete protective frame and mould is also served as on periphery, nothing is filled in centre Sand concrete is molded, only cement and coarse aggregate and composite fertilizer, and to high alkalinity ring in Portland cement concrete pore Border is transformed, and the program adapts to current scour and the ability of uneven settlement of foundation is poor, and difficulty or ease meet hydraulic engineering to shield The requirement on slope.
In addition, the typically no sewage network in town and country river course, rainwater arbitrarily discharge, arterial drainage construction criteria is low, water conservancy bar Part is poor, causes river channel sedimentation to block serious, and river channel erosion is serious, once run into rain heavily when river water level it is higher, some areas Rainwater row does not go out, and forms waterlogging;For river course dust alleviation work by many effect of natural conditions, operating type is numerous, common are The modes such as the water surface (touring) is manually salvaged, water surface machinery is kept a public place clean, bank (touring) is manually salvaged and interception floating object is salvaged;Respectively Planting operating type has its feature, but does not solve the problems, such as rural floater in river pollution fundamentally;Town and country river course floats The periphery rainwater that is derived partly from of thing flows to the stalk mixed during river course, leaf, house refuse, polybag etc..It is existing Slope protection plan can not effectively intercept above-mentioned debris and enter river course with rainwater.
There is provided one kind for this present invention and can effectively intercept above-mentioned debris and enter river course with rainwater, adaptation current scour and ground The ability of base differential settlement is strong, difficulty of construction is small and the construction period is short, can place of production metaplasia production, field-installed town and country river course Bank protection system and method for paving.
The content of the invention
The present invention for solution known technology present in technical problem provide one kind can effectively intercept above-mentioned debris with Rainwater enters river course, and the ability for adapting to current scour and uneven settlement of foundation is strong, difficulty of construction is small and the construction period is short, can Place of production metaplasia production, field-installed town and country river course slope protection system.
The present invention is adopted the technical scheme that to solve technical problem present in known technology:
A kind of town and country river course slope protection system;It is characterized in that:Including the bank protection body along the domatic laying in river course, positioned at bank protection body The enclosing body that top is laid along river course edge;The bank protection body is mated formation by protection slope panel to be formed, and the enclosing body is by shore protection enclosing Monomer and collecting-tank series connection, which are mated formation, to be formed;The protection slope panel is included on two groups of opposite faces of panel body, the panel body Buckling groove and fastening tenon provided with mutual cooperation;
The shore protection enclosing monomer includes enclosing body, and the enclosing body includes horizontal segment and slope section, the level Water transport channel is prefabricated with transverse direction in section;The lower surface of the slope section of the shore protection enclosing monomer is provided with buckling groove or fastening Tenon;Intake chamber is provided with the upper surface of horizontal segment, the intake chamber is provided with removable grate plate;
The collecting-tank is disposed between several shore protection enclosing monomers, and with adjacent shore protection enclosing monomer Water transport channel connects;The collecting-tank includes pregroove marks, and the both ends of pregroove marks are provided with and both sides shore protection enclosing monomer water transport channel The inlet opening of connection, drainage channel is being provided with along slope direction;The top of the collecting-tank is provided with detachable grate plate;Catchmenting The detachable installation filter screen in pond internal drainage passway position.
The present invention can also use following technical measures:
The horizontal segment of the enclosing body and the lower surface of slope section and/or the lower surface of protection slope panel are provided with support and positioned It is raised.
One end of the water transport channel is provided with taper positioning assembly bench, the center of taper positioning assembly bench be provided with it is defeated The centre bore of aquaporin connection;The other end of water transport channel is provided with coordinates taper concave surface, taper concave surface with taper positioning assembly bench Center connected with water transport channel.
