Abstract

The utility model relates to the field of hydraulic energy engineering, in particular to an overhead U-shaped channel. The overhead U-shaped channel is formed by a U-shaped groove, a supporting top frame, round expansion joints, a groove-shaped expansion joint, a transverse underframe, a longitudinal underframe, a support chip and a water stop sheet; the overhead U-shaped channel adopts an overhead underframe; each two adjacent sections of overhead U-shaped channels are connected by clamping grooves of the overhead U-shaped channels; the support chips and dowels are arranged at the corresponding positions; the longitudinal underframe and the transverse underframe are directly paved on the ground; the round expansion joints are arranged at both ends of the U-shaped channel; the groove-shaped expansion joint is arranged between the round expansion joints; along the length direction of the U-shaped channel, water outlets are distributed at both sides of the channel; and trash racks and gates are respectively at the front and rear positions of the water outlets. The overhead U-shaped channel is simple to construct, has removability and is easy to popularize.

Description

The U-shaped channel of overhead type

Technical field

The utility model relates to hydraulic engineering field, the particularly U-shaped channel of a kind of overhead type.

Background technology

Although widely used U-shaped channel has near the optimal hydraulic section at home at present, the water delivery sediment transport, the opposing basic native frost heaving failure ability stronger, globality is better, take up an area less, the characteristics such as labor and material saving, but compare itself with the U-shaped channel that this paper recommends and still had some problems, because practical at present U-shaped channel excavates or fills ground according to the orographic condition needs, so engineering construction still accounts for some soils, it is subjected to the constraint of orographic condition larger in addition, landform is more uneven, and corresponding construction volume is also larger.Although compare the ability that the channel section channel has certain native frost heaving failure of opposing base with rectangle, trapezoidal section canal, it still is subjected to the impact of basic native frost heaving failure and underground water.Now widely used U-shaped channel adopts concrete cast-in-situ to build mode basically, and this construction relates to a variety of constructional materialss, if the works area does not possess the condition of gathering materials on the spot, engineering construction is brought difficulty.In addition, the constraint of construction climate condition.Because channel directly is connected with ground, so although adopt certain measures of preventing water, along with the aging federation generation Seepage of channel, and the utilization rate of reduction channel water.

Summary of the invention

The purpose of this utility model is to provide a kind of overhead type U-shaped channel, the technical problem that exists to solve the various channels of present use.

the purpose of this utility model is achieved in that a kind of overhead type U-shaped channel, it is by U-lag 1, support upper frame 2, circular expansion coupling 3, flute profile expansion coupling 4, horizontal underframe 5, vertical underframe 6, support chip 7, sealing piece 8 consists of, overhead type U-shaped channel adopts the overhead type underframe, each section overhead type U-shaped channel is connected by its draw-in groove, use support chip and pin in the corresponding position, vertically underframe 6 and horizontal underframe 5 are directly on the ground, circular expansion coupling 3 is arranged in the two ends of U-shaped channel, flute profile expansion coupling 4 is arranged therebetween, length direction along the U-shaped channel, lay out the mouth of a river in channel both sides, and arrange respectively trashrack and gate at the front and back position place of delivery port.

Use the beneficial effect of novel overhead type U-shaped channel to be: on the material of building, new breakthrough to be arranged, be that novel overhead type U-shaped channel does not re-use the materials such as cement, sandstone, and mainly use the materials such as glass fiber reinforced plastic (or UPVC plastics) and double-layer rubber skin, there has been variation the form of construction work aspect, be that overhead type U-shaped channel does not basically need excavation or fills ground, directly on the ground, be not subjected to the impact of basic native frost heaving failure and underground water, the constraint of engineering construction climate, geographic and geomorphic conditions is less, and construction is simpler.The U-shaped channel is made by a series of batch production processes, and its surface is very smooth, and roughness is very little, and the water delivery transportability of sediments is stronger.Overhead type U-shaped channel directly on the ground, be convenient to dismounting, can reuse elsewhere, this just greatly reduces the construction investment of response, and the time and labour saving is because adopting built on stilts mode, so obviously raise at the bottom of canal, advantage can direct supporting drip irrigation equipment whereby, and water-saving result is obvious, improves water use efficiency.

The specific embodiment

a kind of overhead type U-shaped channel, as Fig. 1, Fig. 2, shown in Figure 3, it is by U-lag 1, support upper frame 2, circular expansion coupling 3, flute profile expansion coupling 4, horizontal underframe 5, vertical underframe 6, support chip 7, sealing piece 8 consists of, overhead type U-shaped channel adopts the overhead type underframe, each section overhead type U-shaped channel is connected by its draw-in groove, use support chip and pin in the corresponding position, vertically underframe 6 and horizontal underframe 5 are directly on the ground, circular expansion coupling 3 is arranged in the two ends of U-shaped channel, flute profile expansion coupling 4 is arranged therebetween, length direction along the U-shaped channel, lay out the mouth of a river in channel both sides, and arrange respectively trashrack and gate at the front and back position place of delivery port.Adopt overhead type U-shaped channel, basically need not excavate or banket, vertically underframe and horizontal underframe directly are layered on the ground, and underframe is connected by circular, flute profile expansion coupling with the support upper frame, and expansion coupling has the effect of regulating height, employing double-layer rubber sealing piece 8 between each section U-lag simultaneously.
