Description
Technical field
The utility model relates to a kind of coastal reclamation area and irritates drainage technique, and row's irrigation canals and ditches are irritated in specifically a kind of coastal reclamation area.
Background technology
Enclose and cultivate and develop coastal beach land resources the important component part that is the territory comprehensive improvement, the water conservancy auxiliary construction is the basic industry of beach land resources comprehensive development and utilization.The retaining tide in new reclamation area removes stain, retaining water drainage etc. and all be unable to do without hydraulic engineering; Build production and economic development that essential water conservancy projects often can promote the reclamation area effectively well; Accelerate the comprehensive development speed of land resources. production capacity; Must solve the problem of salt, plate, sore, need one and support the process of cultivating.
After enclosing and cultivating, coastal reclamation area begins to build ejectment water system and corresponding conveyance system; And formation of land, lean on rainfall nature desalting soil, because of its mucky soil earth salt content is high, have strong corrosion property; And because of strong wind erosion and water erosion effect, soil erosion takes place very easily.The coastal new directly soil property irrigation canals and ditches of excavation only just deposited and the level land of periphery with elevation in 5 ~ 6 months.Supporting irrigation and drainage system with functions irrigation canals and ditches adopt traditional material and sectional form, and the concrete canal of salt tolerant alkali is the hard side slope, and easily because of yielding the damaging of coastal reclamation area soil, cost is also higher simultaneously.Closed drainage also be since closed drainage exist cost of production high, be prone to stop up, be prone to aging shortcoming, easy care not in process of production.These unfavorable factors have brought certain degree of difficulty for the water conservancy construction in new reclamation area.Therefore, need the cost novel filling row irrigation canals and ditches technology lower, applied widely of research, to satisfy the high area of salt alkali content such as the coastal reclamation area needs of irrigation and drainage smoothly.
Summary of the invention
The purpose of the utility model is to provide a kind of coastal reclamation area novel filling row irrigation canals and ditches technology; This technology can effectively solve coastal reclamation area drainage of soil irrigation canals and ditches side slope yielding, cave in and alluvial and the very serious problem of soil erosion; Have anti-seepage effect simultaneously, play the effect of carrying out the draining desalinization of soil by flooding or leaching and irrigation smoothly.
The purpose of the utility model realizes through following technical scheme:
Row's irrigation canals and ditches are irritated in a kind of coastal reclamation area, it is characterized in that: this filling row irrigation canals and ditches comprise hard baffle plate and flexible layer, and said hard baffle plate is arranged on the inboard and perpendicular to the ground of the row's of filling irrigation canals and ditches both sides side slope; Be arranged on the cross-section of river outer surface that irrigation canals and ditches are arranged in filling with the suitable flexible layer of cross-section of river shape of filling row irrigation canals and ditches; The two ends of flexible layer are connected with the top of hard baffle plate; Said flexible layer comprises lamina reticularis and geotechnological layer of cloth, and geotechnological layer of cloth is tiled in the outer surface of the cross-section of river of the row's of filling irrigation canals and ditches, and lamina reticularis is arranged on the geotechnological layer of cloth outside.
In the utility model, said hard baffle plate is applicable to the high areas of salt alkali content such as coastal reclamation area by salt tolerant corrosion resistance material engineering plastics, stainless steel or glass fiber reinforced plastic manufacturing.
Hard baffle plate and flexible layer connect through hasp; Flexible layer is fixed on through rivet tiling on the hacking levelling course of the cross-section of river of the row's of filling irrigation canals and ditches.Said geotechnological layer of cloth is vinyon cloth, polyvinyl chloride coating materials, gentle felt coating materials, malthoid coating materials or glass wool cloth coating materials.Hard baffle plate and rivet are fixed on flexible layer on irrigation canals and ditches soil property surface, form the filling row irrigation canals and ditches with certain intensity.The spacing M of fixing rivet confirms that according to the concrete soil in locality the fixing flexible layer gets final product.
The advantage of the utility model is: 1, adopt the hard baffle plate as stress surface; Adopt rivet that flexible layer will be fixed on the soil property surface, the lamina reticularis of flexible layer has certain hot strength, can resist the destruction of soil property irrigation canals and ditches distortion to the top layer; Geotechnique's rete prevents soil erosion of soil property irrigation canals and ditches and seepage; Play preventing erosion, avoid the irrigation canals and ditches alluvial, reach the effect of carrying out irrigation and drainage smoothly; 2, material therefor has corrosion resistance, is applicable to the high areas of saliferous alkali number such as coastal reclamation area; 3, flexible layer does not limit irrigation canals and ditches cross dimensions and form, and application is wide; 4, the utility model can reuse, and saves cost; 5, finish using recyclablely, do not influence local environment, pollution-free, have low-carbon (LC), environmental protection and sustainable characteristics.
The utility model is that the filling row irrigation canals and ditches of coastal reclamation area reclamation are new, applicable to the irrigation canals and ditches of different section size such as trapezoidal, U type and model.Satisfy the filling row irrigation canals and ditches requirement in the coastal reclamation area reclamation process.
