Hollow drainage field ridge with field ridge sluice gate

Abstract

The invention relates to a hollow drainage field ridge with a field ridge sluice gate. The drainage field ridge on the side wall of a field ridge is built of brick stone, has sufficient drainage fall, can enable a tail section to flow into a branch canal or flow into a river below the transverse field ridge and is respectively arranged beside crossed field angles; and a sunk pit and a cover plate in the vicinity range outside the sluice gate at the tail end at the intersection of the field ridge with the sluice gate. The drainage field ridge has the advantages of rapidly draining irrigation water, stormwater and fierce water, reducing flood discharge pressure of an irrigation ditch, preventing crops from being drown, reducing the loss of nutrients in soil, being conductive to air permeation of the soil and growth of the crops, resisting stormwater erosion, controlling weeds on the border of a field, dual purposes as a drainage channel and an aisle ridge, preventing affecting serial irrigation operation of different pieces of the field, avoiding field immersion disputes and creating high-yield conditions for the crops; since soil is replaced with a bag sealed ointment-like plug body, water can be blocked without excavating a road, the water-blocking soil can be prevented from block a water channel, the plug body can automatically effectively tightly plug the sluice gate, thereby realizing rapid, labor-saving, time-saving and effort-saving plugging and removing; in addition, the plug body is stored on site and can be use at any time; and a concealed pipeline of a power grid underground is buried at the outer end of the wall of the ridge.

Description

technical field [0001] The invention relates to a field ridge with drainage function. Background technique [0002] Pingba Irrigation District has abundant water conditions, which are conducive to the development of economic production of vegetables in winter and spring. The development of this production is one of the main ways for farmers in Pingba Irrigation District to get rich. However, the terrain of Pingba is flat, and the drainage drop between fields and irrigation canals, or between fields and fields, is higher than the bottom level of the cultivated layer of fields or even has no drainage drop, and there is no drainage canal between irrigation canals; drainage and irrigation There are very few good fields that are convenient, especially for easy drainage. Most of the fields do not have the advantage of directly facing branch canals or river drainage, but must drain to irrigation canals. There is a lot of waiting time, and the drainage has to go to the source to cu...

Problems solved by technology

[0004] From the above design, it can be seen that Masonry and rectangular prefabricated pipes are used to form ridge gates, and the inner cavity has a drainage ditch whose designed total flow height is lower than the bottom level of the cultivated layer along the line. replace the soil ridges in the same direction between the ridges along the two irrigation canals, or the solid ridges with concrete surface , to overcome the lack of cross-sectional area of ​​the circular tube cavity and the consumption of building materials outside the tube, the most important thing is that the drainage drop is higher than the bottom level line of the cultivated layer and there is no drainage drop in the flat dam strip field or non-strip field Provide unimpeded drainage system with sufficient drainage head to prevent irrigation canal water from harming good fields along the line, timely discharge irrigation water, rainwater and irrigation canal soaking field water, and drain water from the system to avoid irrigation canal water from blocking the drainage outlet or mis-irrigating fields Blocking, avoiding blocking the irrigation mouth, it is necessary to wait for the field water to drain before proceeding, which wastes a lot of waiting time, and allows the irrigation canal to accept the drainage of the field when the irrigation canal needs to be connected in series. The river flows to other irrigation canals downstream, reversing the status quo of low-yield flooded fields and lower wet fields, promoting crop growth, drainage canals and aisles and ridges, avoiding delayed water closure or drainage damage to adjacent fields, affecting farming and causing disputes over soaked fields, and reversing soil ridges It is often attacked by frost, washed by heavy rain, and damaged by drought and cracks, resulting in long-term labor to repair the backward appearance of sick field ridges, and avoiding the role of perennial labor-intensive cleaning of weeds on the edge of the field; the cavity above the total flow height is designed to discharge heavy rain water, reducing the flood pressure of irrigation canals, and avoiding the flooding of large fields along the line by heavy rains and drowning crops, resulting in the loss of the season; The ridge gates along the line are respectively set on the two side walls of the field ridge next to the crossing field corners, corresponding to each other. , it plays the role of reducing the construction cost of the field ridge and saving the construction materials of the ridge body by using one sinkhole and a set of cover plates for multiple gates; At the crossing of the field ridge with a gate, there are sinkholes and covers beyond the vicinity of the gate at the end of the place , the sinkhole plays the role of depositing sundries that fall into the ditch by mistake, preventing them from entering the ditch (sediment will be washed away with water under the condition of water pressure and will not deposit), and ensuring the smooth flow of the ditch in the ridge. The cover plate is Outlets for regular clearing of sunken objects; The bottom of the ridge has a substructure beyond the side walls at both ends , to enhance the self-bearing capacity of the field ridge (that is, the drainage ditch) and avoid the deflection of the ridge body; The field ridge sinkhole section is composed of the bottom structure and brick masonry side walls plus a cover plate , to facilitate the balance of the ridge surface span between the upper and lower fields, to set several gates at both ends of the cross field corner, to set the cover plate retaining edge and squatting edge body; The remaining sections are a plurality of rectangular prefabricated pipes that are connected together on the underlying structure by cement mortar. The cross-sectional connection joints between the pipe bodies are connected by the cross-section joints, the inner end side wall barrier mold, and the cross-section connection gap of the barrier. Cement mortar is poured into the side wall of the inner end, so that the prefabricated pipe is densely packed along the bottom structure to form a whole , wherein the prefabricated pipe plays the role of prefabricating the required pipe materials in advance and increasing the laying speed, and the barrier mold is used to force the gap to be uniform and show the entire connection seam, which is convenient for pouring cement mortar into the seam and filling the seam tightly. , prevent the mortar from leaking and abdicating, save cement mortar and realize the high-quality purpose of effective airtight connection; There is an arch phenomenon under the top of the prefabricated tube inner cavity or rounding at both ends of the top ; Play the role of increasing the strength of the ridge cavity, especially increasing the compressive strength of the top structure, so as to reduce the design thickness of the cavity; The prefabricated pipe ridge body consists of a ridge body that is integrally built with a brick side wall and a cover plate with an arched phenomenon on the bottom surface. , play the role of taking local materials and using them, that is, consuming excess bricks; The drainage ditches within the scope of each field block of the ridge each have a section of sinking bend or arc-shaped sinking bend, each of which is located at the outer part of the downstream end of each sinkhole, and each of the bends The bottom of the top structure has a corresponding arc-shaped sinking part , which can not only increase the thickness of the top structure of the field ridge, ensure that the agricultural machinery crosses without breaking the top structure, but also does not reduce the cross-sectional area of ​​the inner cavity of the culvert; The top of the roof structure, the ridges on both sides of the center line are parallel to the ridges at the front and rear ends , play the role of water blocking and passing functions; On the ridge surface other than the two sides, there is a rounded or chamfered downhill that reaches the upper part of the field surface of the side wall, or the surface of the field surface is rough or has anti-skid stripes , to reduce the height of the side walls on both sides of the field ridge, facilitate the horizontal crossing of the field ridge by agricultural machinery, avoid damage to the lateral sides of the ridge surface, and become a special import and export section for agricultural machinery across the field ridge; The dislocation side body formed by the downhill and the side walls at the front and rear ends is a smooth side body with chamfered and rounded shapes, rough surface or non-slip stripes , its chamfering and rounding can smooth the dislocation side body, which is conducive to the oblique crossing of agricultural machinery, and the rough surface or anti-skid stripes can prevent slipping and slipping; The surface of its top structure is a slightly arched rough surface or a surface with non-slip stripes , play the role of preventing ridges from accumulating water and road slipping; Apply transparent long-lasting waterproof material to the outer surface above the ridge surface , to prevent the surface from absorbing heat, avoid high road temperature factors caused by frequent exposure to the hot sun, and sudden heavy rains that cause thermal expansion and contraction of the masonry ridge, and prevent water from frequently infiltrating into the interior of the surface, which will freeze and crack the masonry in winter The function of protecting the body from the above-mentioned invasion and allowing it to be used permanently; There is rounding at both ends of the bottom of the gate , which is beneficial to the blocking body to block the side gap of the gate; On the side walls at both ends near the middle section of the gate, there is a vertical rib respectively passing through a baffle barrier. , it plays the role of sealing the ointment-like blocking body in the barrie...
