Description
Technical field
This utility model relates to water conservancy equipment field, especially relates to a kind of field irrigation " u "-shaped concrete water-saving channel.
Background technology
China's water resource is poor, and using water wisely is state basic policy. In total water consumption, agricultural water accounts for more than 70%, and therefore, agricultural water conservation is the water-saving major part of China, has a high potential. Now, China's agricultural water conservation carries out sprinkling irrigation in a large number, drip irrigation high-efficiency water-saving mode, water-saving result is notable, but investment is very big, and use is limited in scope, popularizing area is less, the irrigation method in a large amount of farmlands, still based on channel, also has the field irrigation in some places even also adopting Tu Qu, field water utilization rate only about 50%. Waste substantial amounts of water resource. In recent years, under the promotion of China's water-saving policy, field irrigation field ditch adopts precast concrete " u "-shaped channel hydraulic pipeline on a large scale, irrigates effect and improves, and water-saving result is fairly obvious, one of main way of promotion having become as China's agricultural water conservation.
But, while extensive employing precast concrete " u "-shaped channel, also expose some problems, drastically influence the service life of water-saving result and channel. Mainly:
The structure problem of precast concrete " u "-shaped channel.
The precast concrete " u "-shaped channel currently used, form of fracture adopts 40mm equal thickness " u "-shaped structure, due to weight concrete weight, installation is protected for ease of building, only having 400mm length time prefabricated, weight is about 50kg, and cement mortar seam used at the scene by these prefabricated components, the wide 30mm of seam, connects into a field irrigation channel. Precast length is short, and Construction Joint is many, and work on the spot amount is big, is the primary structure problem of this precast concrete " u "-shaped channel. Existing U-shaped concrete canal single-unit length is short, from great, and be connected with each other and design without self sealss, and connecting sewing must be in the milk jointing encapsulation process, and site operation amount is big. And cause in canal that connecting sewing exceeds canal body and caused that water resistance increased, and filling can not be integrally forming with prefabricated canal due to connecting sewing, connecting sewing infiltration situation also ratio is more serious, causes losing on the way in water delivery process relatively more. In addition the factor such as northern area weather freeze thawing, the destruction of channel is serious, and service life is short.
The seam quality problem of precast concrete " u "-shaped channel.
Prefabricated concrete " u "-shaped channel component only has 400mm length, behind scene, connects with cement mortar structure seam, the wide 30mm of seam, and connecting sewing is a lot, and the cement mortar quality that scene is mixed and stirred is difficult to control, and structure seam leakiness is second-rate. These seams are through the freeze-thaw cycle in a winter, and just deform cracking, and much just come off breakage, and after using several years, whole piece channel all torsional deformations, badly damaged, water-saving ability is very poor, and some channel is accomplished by reprocessing or again building protecting, and causes very big waste.
The concrete quality problem of prefabricated " u "-shaped channel
The concrete strength of prefabricated " u "-shaped channel is C15, adopts compression molding. The prefabricated " u "-shaped channel component strength of this molding mode is relatively low, rough surface, voids and pits, leakiness. Such channel hydraulic pipeline ability is low, and impermeability is poor, and through freeze-thaw cycle in winter, xoncrete structure is just frozen to burst and is broken.
The precast concrete " u "-shaped channel connecting sewing currently used is many, and structural integrity is poor, and on-the-spot structure seam difficult quality controls, and prefabricated component concrete strength is low and of poor quality, and service life is short, is universal phenomenon.
Based on this, this utility model provides a kind of field irrigation " u "-shaped concrete water-saving channel to solve above-mentioned technical problem.
