Abstract

The utility model discloses a unit section of a farmland drainage canal, wherein a group of rib plates (2) perpendicularly connected with individual canal walls (1) to extend towards the outer sides of the canal and erected in the vertical direction is arranged on the canal walls (1) erected in the vertical direction on the left side and the right side respectively; moreover, the top faces of the rib plates (2) and the canal walls (1) on the left side and the right side are connected with a horizontal cover plate (3) respectively; the canal walls (1), the rib plates (2) and the cover plates (3) of each side are connected respectively and integrally; another group of columnar horizontal braces (4) parallel with the rib plates (2) is arranged between the cover plates (3) of two sides; and two ends of each horizontal brace (4) are connected with the cover plates (3) of the two sides respectively and integrally, so that the whole unit section is connected into a component. The unit section of the farmland drainage canal is good in stability and can effectively resist the extrusion force of soil on two sides of the canal; and therefore, the canal walls (1) of the two sides are difficult to collapse and fall.

Description

Farmland water drainage canal elementary section

Technical field: the utility model relates to a kind of farm irrigation facility, i.e. farmland water drainage canal.

Background technology: existing farmland water drainage canal still is Tu Qu a lot, promptly in the farmland, digs out a ditch and drains flooded fields.Paste the canal wall with precast plate, or it is just more and more to smear the farmland water drainage canal of canal wall with cement mortar.Even if but the adherent water drainage canal of precast plate; Both sides Qu Bi is equivalent to Yi Tiaoqiang separately, and stability is very poor, again because the water drainage canal degree of depth is bigger; Channel both sides soil extruding force is big; No matter be the adherent water drainage canal of Tu Qu or precast plate, both sides Qu Bi subsides, avalanche is difficult to avoid, and needs often cleaning finishing.

The utility model content: the purpose of the utility model provides a kind of farmland water drainage canal elementary section, and this elementary section good stability can effectively be resisted the soil extruding force of channel both sides, thereby both sides canal wall is difficult for subsiding avalanche.

For this reason; The technical solution that the utility model proposes is; A kind of farmland water drainage canal elementary section; Comprise the canal wall that high vertical such as the left and right sides is erect, one group of floor with the vertical vertical setting of extending to the channel outside of linking to each other of canal wall is separately all arranged on the canal wall of said each side, the floor of each group is equal at interval along channel length direction.Left and right sides floor end face and canal wall end face all are connected with the cover plate of a level, and the canal wall of each side, floor, cover plate link into an integrated entity respectively.Between two side cover plates, have one group of columnar water parallel with floor to support again, each horizontal brace evenly distributes along channel length direction, and the two ends of each horizontal brace link into an integrated entity with two side cover plates respectively, thereby the whole unit section is connected to become a member.

Therefore; The utility model has constituted a frame shape member; Not only canal wall in the left and right sides is connected with each other by horizontal brace; And also having one group of floor that extends laterally on every side canal wall, its stability greatly improves with the ability of resisting channel both sides soil extruding force, thereby both sides canal wall is difficult for subsiding, avalanche.

Below in conjunction with accompanying drawing and embodiment the utility model is further described.

Description of drawings: Fig. 1 is the front view of the utility model elementary section;

Fig. 2 is the vertical view after Fig. 1 lifts right side one angle cover plate 3;

Fig. 3 is the left view of Fig. 1;

Fig. 4 is the local longitudinal sectional drawing of horizontal brace 4 among Fig. 1;

Fig. 5 is the profile of Fig. 4.

The specific embodiment: embodiment 1 is extremely shown in Figure 3 like Fig. 1.Canal wall 1 grade in the left and right sides is high, erects with vertical.One group of rectangle floor 2 of erectting with the vertical of the canal wall 1 vertical extension outside channel that links to each other is separately all arranged on every side canal wall 1; Every group of floor 2 equates along channel length direction at interval; Spacing between adjacent two floors 2 is 1 meter; Can be greater or lesser, the number of every group of floor 2 is determined by the length of elementary section, but can not be less than 2.Rectangle floor 2 also can be up-narrow and down-wide trapezoidal, and stability is better.Can as shown in Figure 2ly all there be floor 2 rear and front end of elementary section, also can all not have, and can also an end has and the other end does not have.Both sides floor 2 end faces and canal wall 1 end face all connect the cover plate 3 of a level separately, and cover plate 3 has been arranged, and can pile up retaining wall above that.The width of every cover plate 3 generally equates with the thickness sum of floor 2 top width and canal wall, but also can be wideer or narrower.The canal wall 1 of each side, floor 2, cover plate 3 all link into an integrated entity.Between two side cover plates 3, there is one group to support 4 again with floor 2 parallel columnar waters, each horizontal brace 4 two ends links into an integrated entity with two side cover plates 3 respectively, thereby the whole unit section is connected to become a member.The section configuration of horizontal brace 4 is generally rectangle, and thickness is greater than the front and back width about it.Section configuration also can be polygon, prismatic, even circle, ellipse etc., but is good with rectangle.Horizontal brace 4 evenly distributes along channel length direction.So-called evenly distribution be meant that not only adjacent two horizontal braces 4 equate at interval, and each horizontal brace 4 is the center symmetric arrangement with elementary section fore-and-aft direction central plane all.The spacing of adjacent two horizontal braces 4 is 5 meters, also can be greater or lesser; The number of horizontal brace 4 depends on the length of elementary section, but can not be less than 2.

In addition, the both sides canal wall 1 of embodiment 1 also can not be that vertical is erect, and erects with V-shape.

To shown in Figure 3, the elementary section all around is symmetry all, but also can be all asymmetric like Fig. 1.

A plurality of elementary sections connect one section front and back adjacency for one section, have just constituted whole piece water drainage canal.Have seam between adjacent two elementary sections, this has stitched with regard to the one-tenth of nature the shrinkage joint.The longitudinal axis of elementary section can also be the curve of natural torsion, to adapt to the water drainage canal of curved course.

Embodiment 2 is extremely shown in Figure 5 like Fig. 1.The material of whole unit section is a concrete.All is furnished with reinforcing bar in the every horizontal brace 4 by routine; Like Fig. 4, shown in Figure 5; Rectangular cross section be distributed with 4 reinforcing bars 41 up and down, pricking by routine at the length direction of horizontal brace 4 again has one group of stirrup 42, the length of reinforcing bar 41 is greater than the span of both sides canal wall 1; And centered, be the center symmetric arrangement promptly with elementary section left and right directions central plane.Horizontal brace 4 has had the said structure reinforcing bar, has increased the intensity of horizontal brace 4, supports 4 by outside destroy to prevent water.Other parts of embodiment 2 are all identical with embodiment 1, no longer repeat.

After the water drainage canal builds up, filling soil between adjacent two floors 2, and at the bottom of canal, i.e. filling soil and compacting between the left and right sides canal wall 1, like this, the stability of the utility model will further improve with the ability of resisting channel both sides soil extruding force.
