Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings.

Example (b): referring to fig. 1, for utility model discloses a retaining wall with drainage function, including the foundatin plate 1 of bearing the weight of the wall body and prevent landslide slope fixed wallboard 2 and fix the infiltration layer 3 that is used for discharging the interior soil ponding of wall body between slope body and wallboard 2.

Referring to fig. 1 and 2, many pile foundations 11 have been pour in the ground base member soil horizon, and foundation plate 1 has been pour to pile foundation 11 top an organic whole, and foundation plate 1 is a flat rectangle reinforced concrete board of putting, and foundation plate 1 keeps away from the plane middle part on ground and opens along its length direction has one drainage canal 12, and pile foundation 11 can consolidate the soil of installation foundation plate 1, fixes the relative position of foundation plate 1 and ground simultaneously.

The wall plate 2 is poured above the foundation plate 1 and is positioned between the slope base body and the drainage channel 12, the wall plate 2 is a rectangular reinforced concrete plate, one side of the wall plate 2, which is far away from the soil to be retained, is uniformly provided with drainage grooves 25 facing the foundation plate 1 along the surface of the wall plate 2, the bottom ends of the drainage grooves 25 are communicated with the drainage channel 12 of the foundation plate 1, and the top end of the wall plate 2 is provided with a launder 24 communicated with the drainage grooves 25; in order to make the wall plate 2 have impervious effect, different grades of impervious concrete can be selected for pouring according to the rainwater amount in different areas when the wall plate 2 is poured, if the construction area is an area with large rainfall or always with running water, the concrete with high impervious grade should be selected, otherwise, the low grade of impervious concrete is selected.

Referring to fig. 2, for making wallboard 2 and foundatin plate 1 keep stable in structure, when pouring wallboard 2, make wallboard 2 and horizontal plane form an acute angle, pour gusset 21 between wallboard 2 and foundatin plate 1, gusset 21, foundatin plate 1 and 2 three of wallboard form the triangle-shaped structure, when this structure makes retaining wall's structure more stable, make retaining wall can bear bigger slope body pressure.

When the wall plate 2 is poured, a plurality of connecting pieces 23 are conveniently poured towards the slope base body along the length of the wall plate, and the connecting pieces 23 can be poured into T-shaped or L-shaped prefabricated pieces and other prefabricated pieces which form grooves with the surface of the wall plate.

In order to make the retaining wall have the purpose of preventing landslide and all have the afforestation effect simultaneously, it has the planting frame 26 that is used for planting the afforestation plant evenly to be fixed with on the surface that wallboard 2 opened drainage groove 25, and planting frame 26 is an inside cavity one end open-ended box body structure to be equipped with the through-hole that is used for leaking in the bottom, when installing planting frame 26, can make planting frame 26 fix in the outside of wallboard 2 through bolted connection's mode.

The water seepage layer 3 is fixed between the wall plate 2 and the slope matrix, and the water seepage layer 3 is formed by pouring concrete with a water seepage function, so that the water seepage layer 3 is reliably fixed on the wall plate 2.

The connecting piece 23 forms a groove with the surface of the wall board to firmly connect the water seepage layer 3 with the wall board 2, and meanwhile, the groove can accumulate the seepage water in the slope body.

In order to make the seepage water of the soil to be retained flow out of the wall plate 2, the bottom of a groove formed by the connecting piece 23 and the wall plate 2 is provided with an overflow hole 22, one end of the overflow hole 22 close to the seepage layer 3 is higher than the other end of the overflow hole 22, the connecting part of the wall plate 2 and the foundation plate 1 is also provided with the overflow hole 22, and the overflow hole 22 is communicated with a drainage groove 25; the overflow holes 22 arranged obliquely can prevent the flowing water from flowing backwards to the blocked soil through the overflow holes 22 to form accumulated water again when the flowing water flows through the outer surface of the wall plate 2.

The construction process of the retaining wall with the drainage function is as follows:

tamping ground base member soil and slope soil earlier, boring at the ground base member and digging a plurality of counter bores, place pile foundation 11's reinforcing bar in the counter bore, pile foundation 11's steel reinforcement cage eminence ground base member soil, set up the template at ground base member surface mounting foundation plate 1's steel reinforcement cage, concreting, shaping pile foundation 11 and foundation plate 1. Erecting a template of the wall plate 2 above the foundation plate 1, fixing the connecting piece 23 on the template, pouring concrete, and forming the connecting piece 23 and the wall plate 2 into a whole; and pouring water-permeable concrete between the surface of the slope matrix and the wall plate 2 serving as a template to form a water-permeable layer 3.

After this retaining wall is installed, 2 inboard infiltration by in the retaining soil of wallboard permeate water layer 3 infiltration to the ditch inslot that connecting piece 23 and wallboard 2 formed, ponding flows to drainage groove 25 through overflow hole 22, collects to the ditch 12 of foundatin plate 1 in through drainage groove 25.

When heavy rain or the outer wall surface of the retaining wall has running water for a long time, the running water flows into the drainage groove 25 through the running water groove 24 at the top of the wall plate 2, then is collected to the drainage channel 12 of the foundation plate 1 through the running water groove 24, and finally flows into a drainage system, and when the water amount in the drainage groove 25 is large, the overflow hole 22 forming an acute angle with the horizontal plane can reduce the water flow flowing through the drainage groove 25 and flowing back to the retained soil again.

The embodiment of this specific implementation mode is the preferred embodiment of the present invention, not limit according to this the utility model discloses a protection scope, so: all equivalent changes made according to the structure, shape and principle of the utility model are covered within the protection scope of the utility model.
