Detailed Description

It should be noted that, in the present invention, unless otherwise explicitly specified or limited, the terms "mounted," "connected," "fixed," and the like are to be construed broadly, and may be, for example, fixedly connected, detachably connected, or integrally connected; they may be directly connected or indirectly connected through an intermediate, and those skilled in the art can understand the specific meaning of the above terms in the present invention according to the specific situation.

In the present invention, the terms "upper", "lower", "left", "right", "top", "bottom", "inner", "outer", and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the drawings, and are only for convenience of description and simplification of description, but do not indicate or imply that the device or element referred to must have a specific orientation, be constructed in a specific orientation, and be operated, and thus, should not be construed as limiting the present invention.

The utility model relates to a slope keeps off native combined member mainly includes that base 1 that is used for burying in the soil below the road bed that fig. 5-7 are shown and that fig. 8-9 are shown to be used for setting up in the side slope outside in order to prevent soil outward collapse keeps off native wallboard 2, and wherein, base 1 and fender native wallboard 2 are the prefab. As shown in fig. 5 and 8, a gap 1a and/or a through hole for the plant root to pass through is formed on the base 1, a tenon 2a is arranged at the bottom end of the retaining wall plate 2, a mortise 1b is correspondingly formed on the base 1, and the tenon 2a is correspondingly inserted into the mortise 1b, so that the retaining wall plate 2 is vertically fixed above the base 1 (as shown in fig. 2).

The construction and assembly method of the slope soil retaining combined member is simply introduced as follows, and the specific operation mode is as follows: the method comprises the steps of firstly burying a base 1 in soil, then backfilling partial soil above the base 1 and tamping to ensure that a mortise 1b is exposed outside, then hoisting a retaining wall board 2, inserting a tenon 2a at the bottom end of the retaining wall board into the mortise 1b, and finally filling soil above the base 1 and tamping to be basically level with the top end of the retaining wall board 2. Because the utility model discloses a modular structure, each component can adopt regular shape (for example flat), is convenient for pile up the transportation, and it is more convenient that the component is protected to the job site hoist and mount than Z type also, and the efficiency of construction is higher, and construction cost is lower. In addition, the retaining wall panel 2 disposed outside the side slope can also play a role of preventing the soil from collapsing outward. It is worth mentioning that, after the slope soil retaining combined member is adopted, under the condition that the floor space is not increased, since the width of the backfill area at the top of the slope (namely, the outer side of the road shoulder 5) is increased, the increased area can be used for increasing the width of the road surface 4 (the original road shoulder 5 can be moved outwards to the backfill area, so that the width of the road surface 4 is increased) and the width of the green belt 6. See fig. 3, under the same circumstances of area (i.e. bottom width is the same in the figure), the right side dotted line has a wider road surface 4 width with the outer fringe parallel and level of curb 5 in the figure, and obviously the lower part has adopted the utility model relates to a road of side slope retaining combined member has a wider road surface 4 width, in addition, see fig. 4 and show, under the same circumstances of area (i.e. bottom width is the same in the figure), the left side dotted line is the same with the left edge parallel and level of greenbelt 6 in the figure, obviously, the lower part has adopted the utility model relates to a road of side slope retaining combined member has a wider greenbelt 6 width. Finally, because the utility model discloses offer the breach 1a and/or the through-hole (the through-hole is not shown in the drawing) that supply the root system of plant to pass down on base 1 for the root system of plant can pass base 1 and grow down, consequently can plant bigger plant (for example arbor) in the soil layer covered above base 1, further promote the afforestation effect of bank one side.

As a preferred structure, as shown in FIG. 5, the middle section of the base 1 is narrowed relative to the two ends, so that notches 1a for the plant roots to pass through downwards are formed at the left and right sides of the narrowed part, and mortises 1b are formed at the end of the base 1. The narrowing of the central section of the base 1 to form the notch 1a has the following advantages: 1. the area of the gap 1a can be made large enough to be more beneficial to the growth and development of the plant root system. 2. After filling and tamping, the base 1 is more difficult to be separated from the soil, and the stability is better.

In view of weight reduction and cost saving, as shown in fig. 7, the cross section of the base 1 is in an isosceles trapezoid shape, and the thickness of the base 1 at the left and right edges is gradually reduced. Further, as shown in fig. 9, the thickness of the retaining wall plate 2 becomes gradually thinner from the bottom end upward.
