Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is further illustrated.
As shown in Figure 1, it is the metope 1 that orthohexagonal prism concrete precast block 2 is formed that the utility model mainly comprises by bottom surface, described each prefabricated section 2 has three to relative side, the two pairs of sides are provided with the through hole 22 of through prefabricated section 2 wherein, described through hole 22 is positioned at the center of place end face, and each prefabricated section 2 is connected together by the reinforcing bar 6 interted between described through hole 22.Adopt bottom surface to be the concrete precast block 2 of orthohexagonal prism to be because the prefabricated section of this shape to be layered on overall structure together more stable, the stressed of all directions can be born, also more attractive in appearance, with four distortion or the concrete of other shapes does not then reach such effect.Prefabricated section is just layered on together and is connected and fixed by cement mortar as a whole by traditional protective slope structure usually, construction is complicated, waste time and energy, and this kind of all-in-one-piece protective slope structure flexibility is poor, once after the inhomogeneous deformation on basis exceedes certain value, often there is the destructions such as crack, even there will be entirety and to collapse phenomenon.As shown in Figure 2, the utility model adopts reinforcing bar 6 by each prefabricated section 2 cross-under together, and make whole metope 1 be provided with cage of reinforcement, overall structure is more stable and be provided with certain flexibility, can adapt to the distortion on basis, there will not be entirety to collapse.If breakage has appearred in prefabricated section, owing to there being cage of reinforcement, so repair also more convenient.
As shown in Figure 4, the size thickness of prefabricated section 2 and the thickness of reinforcing bar 6 are because considering according to domatic size, gradient and residing environment, through hole on prefabricated section 2 22 decides according to the diameter of reinforcing bar 6, because each prefabricated section 2 can intert cross one another two reinforcing bars 6, so the place crossed in centre should be greater than the diameter sum of two reinforcing bars 6, for convenience of making, so directly the diameter of through hole 22 is set to the twice slightly larger than reinforcing bar 6 diameter.
As shown in Figure 3, consider and domaticly interiorly may have some immersions, if immersion can not be discharged in time and may be caused the distortion of domatic matrix or cause soil erosion, so need to arrange some drain holes 21 on metope 1.In order to simplify working procedure, just drain hole 21 can be carried out when making concrete precast block 2, only need place a prefabricated section 2 with drain hole 21 in position just when laying then.In order to make drainage effect reach best, drain hole 21 should be located at the center position of prefabricated section 2 and run through whole prefabricated section 2, like this can be through with the through hole 22 of interspersed reinforcing bar 6 by drain hole 21, and current also can collect along through hole 22 discharges again.
Conveniently interspersed reinforcing bar 6 between each prefabricated section 2, the profile of prefabricated section 2 can be arranged to bottom surface is orthohexagonal frustum, when laying by bottom surface less for prefabricated section 2 upward.So between each prefabricated section 2, just have certain gap, conveniently can observe the position of reinforcing bar 6, be convenient to interting of reinforcing bar 6.More convenient when carrying out jointing with cement mortar 3 pairs of gaps in addition, and make to connect between each prefabricated section more stable.
Object gap between prefabricated section 2 being adopted to cement mortar 3 jointing is not to be connected and fixed as a whole by each prefabricated section 2, and just suitable connection, whole metope 1 is made to have certain globality and stability, outward appearance is also more good-looking simultaneously, when matrix deforms time, the gap place of metope 1 just there will be crack, these cracks can not be caused great impact to metope 1 but be conducive to the observation to bank protection deformed shape, improve to make or repair.Cast-in-situ concrete adjustment block 4 edge sealing is adopted in the surrounding of metope 1; and the key-wall 5 adopting stone masonry to build by laying bricks or stones in periphery is fixed; these two measures are all the protections to metope 1 surrounding; make border more smooth with concrete adjustment block 4 edge sealing; outside reinforces with key-wall 5 again, makes the structure of whole metope 1 more stable.
As shown in Figure 5, below described metope 1, be provided with sand-gravel cushion 7, described sand-gravel cushion 7 adopts nature aggregate making, and sand material maximum particle diameter is not more than 2/3 of cushion thickness, and bed course paves rear watering, and uses utensil compacting.Sand-gravel cushion 7 mainly plays draining, prevents domatic immersion from impacting metope.
