Description
Technical field: the utility model relates to irrigation and water conservancy concrete channel, i.e. concrete gap bridge elementary section.
Background technology: the development of managing along with intensive agriculture, agricultural machinery obtains to be applied more and more widely, and the agricultural machinery such as tractor, harvester comes and goes in great number in farmland, can repeatedly cross irrigation and water conservancy channel.Existing irrigation and water conservancy concrete channel is not passed a bridge, and agricultural machinery across channel, will can only pile up foreign material temporarily in channel, and if straw etc. is as passage, not only inconvenient, also due to the repeatedly spreading of agricultural machinery, concrete channel is usually damaged.
Utility model content: the purpose of this utility model is to provide a kind of concrete gap bridge elementary section of irrigation and water conservancy concrete channel, several elementary section combination is formed passes a bridge, and has both facilitated agricultural machinery to run over gap bridge, and has protected again concrete channel not rolled damage by agricultural machinery.
For this reason, the technical solution that the utility model proposes is, a kind of concrete gap bridge elementary section, mainly comprise the U-shaped elementary section of the end face opening be made up of reinforcing bar and concrete, a reinforcing bar is had at least in this U-shaped elementary section, in U-shaped elementary section, the shape of section is identical with section in the U-shaped canal of adjacent concrete with size, the end face of U-shaped elementary section, a concrete drain cover is had to be connected with two canal walls of U-shaped elementary section, thus form the concrete gap bridge elementary section closed in a cross section, every root reinforcing bar is made up of the two halves section of concave shape, and two halves section is positioned at same vertical plane, the recess of two halves section is relative, the top section phase mutual of the level of their tops overlaps, and be arranged in drain cover, the end section of the level that they are following also has the base plate overlapping and be arranged in U-shaped elementary section mutually.
As can be seen here, the utility model has had drain cover, be equivalent to bridge floor, the utility model is one section in the U-shaped canal of irrigation and water conservancy concrete, it is again a bridge block, the combination of several elementary section can make bridge floor have enough width, and the agricultural machinery such as tractor, harvester just can be conveniently by, also can not damage the U-shaped canal of concrete.
Below in conjunction with drawings and Examples, the utility model is further described.
Accompanying drawing illustrates, Fig. 1 is the partial top view including the U-shaped canal 1 of irrigation and water conservancy concrete of the present utility model;
Fig. 2 is A-A sectional view in Fig. 1.
Detailed description of the invention: embodiment 1 as shown in Figure 1 to Figure 2.The utility model is one section in irrigation and water conservancy channel in the U-shaped canal 1 of concrete.Concrete gap bridge elementary section is made up of reinforcing bar 4 and concrete 3, and before and after it, two walls and base plate form the U-shaped elementary section 2 of an end face opening, and the interior section configuration of U-shaped elementary section 2 is identical with section in the U-shaped canal of adjacent concrete 1 with size, thus can not increase water flowing resistance.The end face of U-shaped elementary section 2, a concrete drain cover 2a is had to be connected with two canal walls before and after it, thus form the concrete gap bridge elementary section closed in a cross section, drain cover 2a left and right directions width is identical with U-shaped elementary section 2 left and right directions width and flush, also can be more a little bit smaller than U-shaped elementary section 2 left and right directions width.Drain cover 2a fore-and-aft direction width is greater than U-shaped elementary section 2 end face fore-and-aft direction width, so drain cover 2a fore-and-aft direction width is greater than adjacent concrete U-shaped canal 1 end face fore-and-aft direction width, and drain cover 2a end face is higher than the end face of the U-shaped canal 1 of adjacent concrete.The wall thickness of concrete gap bridge elementary section can the wall thickness of canal 1 U-shaped with adjacent concrete identical, but with thicker be good, to increase the intensity of concrete gap bridge elementary section.A reinforcing bar 4 is had at least in each concrete gap bridge elementary section, every root reinforcing bar 4 is made up of the front and back two halves section of concave shape, and front and back two halves section is positioned at same vertical plane, the recess of two halves section is relative, the top section phase mutual of the level of their tops overlaps and is arranged in drain cover 2a, and the end section of the level that they are following also has the base plate overlapping and be arranged in U-shaped elementary section 2 mutually.For the concrete gap bridge elementary section that left and right directions width is larger, also by two even more reinforcing bars 4 be made up of front and back two halves section, and a rack can be bundled into by the arrangement of reinforcement at one group of interval.Embodiment 1 can be made in concrete prefabricated member factory, then farmland site assembly is transported to, be connected with the U-shaped canal 1 of adjacent concrete, as shown in Figure 1, a gap bridge is combined into by four concrete gap bridge elementary sections, certainly, the number of the concrete gap bridge elementary section of each gap bridge can increase and decrease, but its left and right directions width must ensure that the agricultural machinery such as tractor, harvester passes through smoothly.
As shown in Figure 2, there are opening 2b in the drain cover 2a central authorities of concrete gap bridge elementary section to embodiment 2, and also there are opening 2b in U-shaped elementary section 2 base plate central authorities, so each concrete gap bridge elementary section is divided into identical front and back two half block, the top section overlapped in each block and end section reinforcing bar 4 expose.Before and after this, two half blocks also can have been built in concrete prefabricated member factory, locate, build concrete at the scene as mould after then transporting to scene, farmland, are closed by upper and lower opening 2b, and front and back two half block is linked into an integrated entity, and all the other are all identical with embodiment 1, no longer repeat.Embodiment 2 is particularly suitable for the rural area of road conditions difference.
So-called left and right directions is the trend following the U-shaped canal 1 of concrete in Fig. 1; Fore-and-aft direction is the direction that canal 1 central plane U-shaped with concrete is vertical.
