Abstract

The utility model discloses a wall plate type ecological retaining wall bank protection structure. A reinforced concrete precast plate pile is arranged at the bottom of the side, adjacent to water, of an original slope in a hitting mode. A soft cushion layer is laid on the top of the precast plate pile, and a reinforced concrete base plate is cast. The top of the precast plate pile penetrates through the cushion layer and is embedded into the reinforced concrete base plate. Vertical connection steel bars are pre-buried in the top face of the reinforced concrete base plate, and a reinforced concrete retaining wall is cast on the vertical connection steel bars. The upper portion of the retaining wall is evenly provided with water draining channels. The retaining wall is of a wall plate type, the bottom end of the retaining wall is connected with the vertical connection steel bars of the reinforced concrete base plate, and horizontal connection steel bars are pre-buried in the bottom of the side, back to the water, of the original slope. Combined bolting and shotcrete are adopted in the original slope, and a rubble concrete layer and a plantation soil backfilled layer are sequentially arranged between the original slope and the retaining wall from bottom to top. The contact face between the inner wall of the retaining wall and the plantation soil backfilled soil layer, the contact face between the rubble concrete layer and the plantation backfilled soil layer and the contact face between the original slope and the plantation backfilled soil layer are paved with root separation films. The wall plate type ecological retaining wall bank protection structure has the advantages of being capable of optimizing the environment of a channel adjacent to a river and reducing water and soil losses, good in stability and easy and convenient to construct.

Description

A kind of wallboard type Ecological Retaining Wall bank protection structure
Technical field
The utility model relates to a kind of barricade bank protection structure, and more specifically, it relates to a kind of wallboard type Ecological Retaining Wall bank protection structure.
Background technology
Bank protection work causes soil erosion in order to prevent river bank because of current scour, controls river gesture, take engineering protection measure.The bank protection structure in traditional navigation channel, river mainly contains reinforced earth bank protection structure, grouts or placed rockfill bank protection structure, cast-in-situ concrete Form Gravity Breast Wall bank protection structure and precast concrete block bank protection structure etc., these bank protection structures are firm, durable, have been widely used in the bank protection work of riverbank, seashore.But also have many deficiencies, for example artificial trace is heavy, destruction ecological environment, and part bank protection structure weight, adds that the bearing capacity of foundation soil that borders on the river is low, and differential settlement etc. easily occurs.
At present, low for the bearing capacity of foundation soil that borders on the river, the problem that settlement after construction is large, can adopt to set sheet pile and improve bearing capacity of foundation soil mode and solve.Wherein sheet pile mainly contains reinforced concrete sheet pile and the large class of steel sheet pile two, though steel sheet pile has good watertightness in bank protection work near water, combination top wall-retaining structure is difficult to effectively reclaim while use and is perishable, and cost performance is not as good as reinforced concrete sheet pile.Except improve bearing capacity of foundation soil, alleviate superstructure load-bearing the differential settlement that can further prevent bank protection structure simultaneously.Wherein wallboard type retaining wall takes up an area few, structure is light, there is good effect, but conventional wall plate type retaining wall need pass through anchor pole drawknot, operation poor efficiency, and by artificialization, channelization completely, destroyed resource function and the ecological functions in navigation channel, also destroyed navigation channel, river biological chain, caused ecological deterioration simultaneously.Given this, in order to solve, existing shore protection barricade sedimentation is large, stability is not enough, destroy the shortcomings such as ecological environment, need badly at present invention a kind of can meet simultaneously stability strong, take into account land and water ecology, effective, the good in economic efficiency Ecological Retaining Wall bank protection structure of easy construction.
Summary of the invention
The purpose of this utility model is to overcome deficiency of the prior art, provides a kind of rational in infrastructure, easy construction, the wallboard type Ecological Retaining Wall bank protection structure that sedimentation is little, greening degree is high.
This wallboard type Ecological Retaining Wall bank protection structure, former side slope near water side bottom set reinforced concrete prefabricated board stake, prefabricated sheet pile top is laid flexible cushion and is also built reinforced concrete floor, prefabricated sheet pile stake top is run through bed course and is embedded in reinforced concrete floor; The pre-buried vertical connecting reinforcement of reinforced concrete floor end face, builds Reinforced Concrete Retaining Walls on it; Barricade top evenly arranges drainage channel, and described barricade is wallboard type, and bottom is connected with the vertical connecting reinforcement of reinforced concrete floor, and at the pre-buried horizontal connecting reinforcement in land side bottom; Former side slope adopts combined bolting and shotcrete, is provided with successively slabstone layer of concrete and plantation back fill course between former side slope and barricade from bottom to top, and lays root separation film barricade inwall, slabstone layer of concrete and former side slope three with the contact surface of plantation back fill course.
As preferably: the pre-buried horizontal connecting reinforcement in described barricade land side bottom is equidistant.
As preferably: described barricade near water side arranges plant Hanging Basket.
As preferably: described drainage channel is located at barricade top, plantation back fill course bottom, and gutter is set in drainage channel, and gutter arranges anti-filter geotextiles in land side end.
As preferably: described flexible cushion adopts rubble compacting to form, and thickness is 200mm~400mm.
As preferably: described prefabricated sheet pile is provided with inverted trapezoidal stake end cutting edge.
As preferably: prefabricated sheet pile stake top is run through flexible cushion and embedded 150mm~250mm in reinforced concrete floor.
The beneficial effects of the utility model are: the water that the gutter of (1) outsourcing anti-filter geotextiles is conducive to plant in backfill after barricade is discharged in time, reduce the lateral earth pressure of barricade, strengthen whole structural stability.(2) barricade near water side plant Hanging Basket is set, and plant herbaceous plant, both can purify water, regulate land and water ecology, have again environmental protection effect.(3) the pre-buried horizontal connecting reinforcement of wallboard type barricade, can strengthen the bonding strength of barricade and slabstone layer of concrete, improves the stress performance of barricade.In a word, adopt barricade bank protection structure described in the utility model can optimize the navigation channel environment that borders on the river, reduce soil erosion, and good stability, easy construction.
